Lewin was famous for his physics lectures at MIT, particularly when they were posted online. The most iconic moment in his course was when he let a big pendulum off in front of him. The point was that it didn't swing back and smash<br />
him in the head, because of energy conversation.<br />
<br />
<br />
<br />
<br />
<br />
<br />
The book is enjoyable, but also a bit strange. It starts out with popular real world physics, but the second half is about his research into X-ray astronomy mostly using ballons. The last chapter is about Modern Art. He is a big collector and he has worked with some artists. I liked the way he used in the end chapter the metaphor "ways of seeing" to unify his interests in art and physics.<br />
<br />
I was disappointed that there were not a lot of discussion of his teaching methods. It does look as though he was an inspirational teacher. In the book he reported that he gave out flowers, when he displayed Maxwell's equations on the screen. Students wrote to him to say they remember the flowers, if nothing else from the course. Students liked the demos as well.<br />

So we are always looking for ways to build in methods to make sure our teaching equips the students with useful jobs skills. One person suggested developing a system for the students to create a portfolio of their skills.<br />
<br />
Last week I read the book "<a href="https://www.amazon.co.uk/Staying-Ahead-Work-portfolio-attitudes/dp/1857032985/ref=sr_1_1?s=books&ie=UTF8&qid=1468179073&sr=1-1&keywords=Staying+ahead+at+work">Staying ahead at work</a>" by Karen Mannering. The subtitle of the book was: "How to develop a winning portfolio of work skills and attitudes?"<br />
<br />
The book was more focused on people already working in a company and helping them get a promotion or a new better job. So there was a lot of stuff about getting a mentor, or a coach,<br />
and the importance of networking. She also suggested writing an "<a href="https://www.kent.ac.uk/careers/sk/skillsactionplanning.htm">action plan</a>" to plan for career development and advancement. It was not particularly useful for students at University.<br />

The book contained a set of chapters about teaching problem solving in diffferent subjects, such as:<br />
<ul>
<li>Biology</li>
<li>Chemistry</li>
<li>Medicine</li>
<li>Programming</li>
<li>Mathematics</li>
<li>Physics</li>
<li>Trouble shooting (finding problems in machines).</li>
</ul>
I teach physics and mathematics, this involves trying to get the students to solve problems.<br />
The aim of the book was to see if there were generic methods of solving problems, which are useful for all subjects. In the end I didn't see any conclusion that there was a universal method of solving problems in any domain.<br />
<br />
There was much discussion about the differences between the problem solving skills of experts and novices. Also there was issues about much information the students needed before they started trying to solve problems. Experts would experiment a bit more before they started to calculate. At the end of the solution of the problem, experts would think about better ways of solving the problems.<br />
<br />
The way that TAs explained solutions to problems didn't help students to learn better problem solving techniques. <br />

This module was one of the new Plymouth Plus immersive modules, where the students take a 20 credit module, which last year would have been taught over a year, is now taught in a single month. The students only take this module in the month. So it is essentially a bootcamp for quantum mechanics and astronomy.<br />
<br />
An important part of the content of the module is Astronomy. As part of the practical sessions in the module we used the Immersive Vision Theatre on campus. I was in charge of this part of the course. It was a bit of strain to develop new material for the two sessions every week. One important issue is how to make the sessions interactive, so that the students actually do something, rather than just passively watch.<br />
<br />
Dr. Helen Goodall from Marjon reviewed one of the teaching sessions in the planetarium.<br />

One possible system to give questions to the students is to use a system such as <a href="http://www.socrative.com/">socrative</a>.<br />
This allows students to use smart phones or tablets to answer multiple choice questions. One<br />
important issue is that not everyone will have a smart phone, so the system should allow students with no phone to contribute. This is an important diversity issue, because not everyone will be able to afford a smart phone, or they may not like them. Socrative allows tests to be downloaded. See the example below, which I created.<br />

The course feeds into various engineering degrees. When I look out to the audience I don't see many women students. it could be that there are less than 10% female students. I am not sure what I can do to improve this. I try to be careful to not use any sexist language, or use any examples that depend on gender. (This is not too hard when we study electrons and atoms).<br />
<br />
It looks like there are professional societies, whose main purpose is encourage girls to study engineering. See for example: <a href="http://www.wes.org.uk/">The Women's Engineering Society.</a>CraigMcNeilehttp://www.blogger.com/profile/00292137283015549566noreply@blogger.comtag:blogger.com,1999:blog-1805096721914791199.post-41688029853072077502016-03-24T08:04:00.003-07:002016-03-24T08:05:18.530-07:00Reviewing a lecture by a senior member of the school. (UKPSF K2 K3 K5 A5)It is departmental policy in the School of Computing, Electronics and Mathematics at Plymouth University, that every staff member review another person's teaching, and their teaching is also reviewed. Typically, people watch other people's lectures.<br />
<br />
This year I reviewed a lecture by a senior member of the school. As I said in the discussion part of the PGCAP course at Marjon, I find it difficult to give advice to senior members of the school. Of course, it is useful to see the teaching styles of other staff members:<br />
<br />
Below is what I wrote. The most useful thing for me, is that I should make<br />
it clear to the students how to use the material in the course. This is<br />
particularly important in the course I teach in the foundation year.<br />
<br />
<br />
<b>What aspects of practice were identified through the peer review<br />process and the subsequent discussion that may be of interest /<br />relevance to colleagues in the School?</b><br />
It was useful to see a very interactive lecture, made possible by the<br />
existence of a booklet of notes. There were a lot of questions from<br />
the students. I liked the way the lecturer told the students how to write notes and get the<br />
most out of the lectures. <br />
<br />
<b>What developmental or enhancement needs were identified through the<br />peer review process?</b><br />
There were some slight problems with the presentation systems at the<br />
beginning of the lecture (mostly caused by me.) It would be better if<br />
this didn't happen. It is not a big deal, but it would make the lecture look more professional. <br />
<br />
<b>Any other comments / points raised that you wish to capture please<br />note these in the section below:</b><br />
Although it was a great lecture -- it was essentially revision of <br />
material taught at a school. Perhaps it would be helpful to the students to make use of<br />
the revision and support material from the <a href="http://www.mathcentre.ac.uk/">mathcentre</a>.<br />

(UKPSF: A3 A4)This last semester I have been teaching in a computer lab with a lecturer and another person. The students are given problems to do in either the computer algebra package called Maple, or the numerical package: Matlab. If the students have problems I go over and help them. I believe that this is giving feedback to the students. However, it is not clear that the classification scheme used by the PGCAP people would regard my activities as formative assessment, or providing feedback.<br />
<br />
The lecturer collected, from students who wanted to, some of their programs. He promised to give them feedback on them. It is nor clear how effective this type of feedback is. He could only check that the format of the programs accords to his style guide. For example, he could check that the program has enough comments.<br />

The Itunes University is one way to deliver content to the students in format that is suited to the ipad mini. Last week, <a href="https://www.plymouth.ac.uk/staff/nicholas-outram">Dr Nick Outram </a>presented a tutorial on using the <a href="http://tyenca.weebly.com/itunes-u-course-manager.html">ItunesU course manager. </a> to create courses.<br />
<br />
It looked like a convenient way to deliver notes to the students. I don't like the way pdf documents are displayed on the Ipad. It looked like a good way to combine video and text in a more coherent way than the Moodle system we use to store all of our teaching material.<br />
<br />
There was a way to input mathematics into the Ibooks system using standard latex format. Looking online afterwards, it is not clear how complete the coverage of latex syntax is. Also there is a lot of material in latex format. It looks difficult to convert a big latex document to Itunes format. I believe that the students could annotate the documents.<br />
<br />
Nick had used the Itunes course manager for a number of courses. It had been popular with the students.<br />
<br />
I think I might use this course in the new mathematical programming module, which I am teaching next year. One of my tutorial students told me he was disappointed that the Ipads were not used more.CraigMcNeilehttp://www.blogger.com/profile/00292137283015549566noreply@blogger.comtag:blogger.com,1999:blog-1805096721914791199.post-67953625991727010182016-03-23T07:54:00.002-07:002016-03-24T05:07:25.994-07:00Do styles of learning exist? (UKPSF: K3,K5)I recently attended an interesting talk by one of the third year student's at Plymouth. The talk was based on her experiences on a placement teaching in a school. <br />
She used some ideas of "styles of learning" in her teaching. This was impressive, because I don't believe that there is any theory taught in that module.<br />
<br />
I have a book called "<a href="http://www.amazon.co.uk/Martial-Arts-Instruction-Educational-Communication/dp/159439024X/ref=sr_1_1?ie=UTF8&qid=1453407607&sr=8-1&keywords=Martial+Arts+Instruction">Martial Arts Instruction</a>" by Lawrence Kane. He uses the <a href="https://en.wikipedia.org/wiki/Myers%E2%80%93Briggs_Type_Indicator">Myers-Briggs MBTI</a> indicators to classify students. I am a bit doubtful about this, because the underlying basic idea came from psychoanalysis such as Jung. In the first chapter he breaks learners into auditory, kinesthetic and visual learners. However, he doesn't provide any references, but just assumes that this classification is true.<br />
<br />
For example , a <a href="https://en.wikipedia.org/wiki/Kinesthetic_learning">kinesthetic </a>learner prefers to learn by touching. It might be clear how to teach elementary mathematics by a tactile method. For example a student could count out objects when they are learning about addition. It is less clear how to learn about more abstract topics, such as complex numbers and partial differential equations. In the book "<a href="http://www.amazon.co.uk/Why-Dont-Students-Like-School/dp/047059196X/ref=sr_1_1?ie=UTF8&qid=1458744481&sr=8-1&keywords=why+do+children+hate+school">Why Don't Students Like School?: A Cognitive Scientist Answers Questions About How the Mind Works and What It Means for the Classroom,</a>" by Daniel T. Willingham, he points out that given that the idea is<br />
for the student to convert a concept into an internal cognitive schema, then the learning style may have little influence on learning of abstract concepts.<br />
<br />
There is paper called: <a href="https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjIyKXMqM3LAhWDRBQKHRV3AqIQFggcMAA&url=http%3A%2F%2Fwww.itslifejimbutnotasweknowit.org.uk%2Ffiles%2FLSRC_LearningStyles.pdf&usg=AFQjCNGCSR_0MU94XRuxCO5F4461ZK2wTQ&sig2=i_h_9_upAD-vdaNBZhiyVA&bvm=bv.117218890,d.ZWU">should we be using learning styles</a> which reviews the evidence for learning styles. It is a long paper, but seems to be a comprehensive review. It is also very readable. The key points I got out of it were:<br />
<br />
<ul>
<li>If students do learn with different learning styles, then because Plymouth University is committed to teaching a diverse range of students, then this should be taken into account.</li>
<li>There are a wide range of different theories about learning styles to choose from. It is not clear which theory is best, or even if a theory is correct.</li>
<li>There are no good empirical studies which test the different learning style models.</li>
<li>One way to determine your learning style is to take a questionnaire. There are commercial companies, which create these questionnaire. There is a lot of money to be made. Particularly, if these methods are used to hire people.</li>
<li>It can be a problem, if student is "diagnosed" as one type of learning. For example, if they decide they are a kinesthetic learner, then they may just assume that they will learn nothing from a set of lectures.</li>
<li>Even if a teacher finds out that a class of students has many different learning styles then somehow the teacher should teach the same material in many different ways to appeal to the spectrum of the classes learning styles.</li>
<li>Rather than focusing on what learning style a student has, it is probably much better to get the student to think about the way they learn -- to try and optimize the process. </li>
</ul>
<br />
My conclusion is that there needs to be much better studies of the effectiveness of the different learning style models, before I need to use them. <br />

However, it is clear that I can't depend on having a whiteboard available to me in rooms I am scheduled to teach in.<br />
<br />
There are some studies of the effect of using the whiteboard versus an interactive whiteboard.<br />
<ul>
<li>For example, <a href="http://pubs.acs.org/doi/abs/10.1021/ed074p262">this paper</a> discusses writing on the whiteboard in relation to the cognitive structure of the students. </li>
<li>There are some studies of comparing using the white board versus an interactive white board. For example, <a href="http://www.edweek.org/dd/articles/2010/01/08/02whiteboards.h03.html">here </a> and <a href="http://www.ascd.org/publications/educational-leadership/nov09/vol67/num03/Teaching-with-Interactive-Whiteboards.aspx">here </a>. </li>
</ul>
There are some <a href="https://www.teachingenglish.org.uk/article/using-board">hints</a> about using the whiteboard.

The topics are essentially electromagnetism and a bit of quantum theory. I mostly use slides to present the material, but I like to work problems on the white board. Unfortunately, this year I am in a room with no board. There is a visualizer, where I can write on the screen. Unfortunately, I can't actually see the screen very well, because it is on the wrong side of the podium. My handwriting is not good and the poor set up of the visualizer is making things worse. One of the students complained to me about my handwriting.<br />
<br />
I want to try to use my Ipad, the department gave me, to project from the Ipad to the screen. One possible App is called: <a href="http://explaineverything.com/support/tutorials/ios/">Explain Everything.</a> I have not yet got a cable to connect my Ipad, but I have been playing with the above App. One of the students asked if I was going to make any podcasts.<br />
Below is my first podcasts.<br />

He is also worried by the separation of research and teaching. <br />
<br />
People like this type of Education model for Universities, because it<br />
involves research with undergraduate students and stresses liberal<br />
arts values.<br />
<br />
It is never clear how accurate the scholarship is of Humboldtian educational values are. I have read the paper: <a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1465-3435.2006.00258.x/abstract"><span style="background-color: white; color: black; display: inline; float: none; font-family: "arial" , "lucida grande" , "geneva" , "verdana" , "helvetica" , "lucida sans unicode" , sans-serif; font-size: 14px; font-style: normal; font-variant: normal; font-weight: bold; letter-spacing: normal; line-height: 14px; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px;">Bachelor of What, Master of Whom? The Humboldt Myth and Historical Transformations of Higher Education in German-Speaking Europe and the US</span> </a>by Mitchel Ash. This paper looks as the author has a better grasp of the material than many people in the PGCAP community.<br />
<br />
Mitchel claims that the principles below are the basic ideas of the Humboldtian educational values.<br />
<ul>
<li><b>Freedom of teaching and learning.</b> Students had as much right to choose their instructors and subjects as professors had to decide what and how they taught.</li>
<li><b>The unity of teaching and research.</b> He thought that learning is a collaborative enterprise, in which ‘the professors are not there for the students, but rather both are there for science.<b> </b></li>
<li><b>The unity of science and scholarship.</b><b> </b></li>
<li><b>The primacy of ‘pure’ science over specialized professional</b><b> training. </b></li>
</ul>
<ul>In his article Mitchel notes that Humboldt's writings on education were unpublished, so were not very influential for a long time, because no one knew about them. His writings were only rediscovered at the end of the 19th century and were used as motivation to reform a system, he had helped to found. The article claims that PhDs were only started to be awarded at the end of the 19th century. Also, it should be remembered that this educational system loosely based on Humboldt's idea, was run, when only 1% of the population attended University, rather than the mass education system we have now.</ul>
In the USA, there are small liberal arts colleges, where students have to take a few science courses when they take humanity courses. Similarly, science students have to take some humanity classes. It looks as though these colleges were influenced bu Humboldt, but since his writings were unknown, Mitchel thinks that this is unlikely. The undergraduate degree seems to have been invented in the USA, so undergraduate degrees did not exist in Germany in the 19th Century.<br />
<br />
The paper ends with a discussion of the Bologna process on trying to create a common standard of University education across Europe.<br />
<br />
Given that Humboldt's ideas, if they existed at all, only worked for a University with only 1% of the population, in a system where there were no undergraduate degrees.<br />

Last year, in my course on foundation level physics was reviewed. The lectures were on the topic of <a href="https://en.wikipedia.org/wiki/Alternating_current">alternating current .</a> The lectures notes I am using have been used for over 5 years and were not written by me. Normally they contain many inline exercises that the students can work through in class.<br />
<br />
Unfortunately, the lectures on alternating current didn't contain many inline exercises. Also I started the lecture with a long review of what we did in the previous lecture. I didn't put in too much detail in the review, because that had been covered in the first lecture on the topic. The reviewer didn't like the lecture too much, because it wasn't very interactive. Also he wanted more background information for the review material.<br />
<br />
I am going to rewrite some of the material on the alternating current. I have started to use a set of web based simulation codes called <a href="https://phet.colorado.edu/en/simulations/category/physics">PHET </a>from the University of Colorado. In principle these can be used to explore questions with the students. One direction the work on reviewing alternating current can go, is to look at Electromagnetic waves. The simulations are designed using ideas from Physics Education Research. For example, they use "think aloud" techniques to find out how the students approach problem solving.<br />
<br />
One way to understand electromagnetic waves is to first start with waves on a string, so this simulation can be used.<br />
<br />

The University is keen for students to be involved in research. However, the background to my research requires an understanding of quantum field theory and Lie group theory, as well as expertise in high performance computing. We don't teach these subjects at Plymouth, so the students don't have the background knowledge.<br />
<br />
The professional bodies for mathematics <a href="http://www.qaa.ac.uk/publications/information-and-guidance/publication/?PubID=2952#.VsNkMClhRyt">has a document </a>describing what mathematics undergraduates should learn on a degree. Actually it is the <a href="http://www.qaa.ac.uk/about-us">quality assurance body</a> in the UK. The document is actually very vague to what knowledge and skills is expected to be learned by the students. The statement about the level of knowledge is interesting. <br />
<br />
<blockquote class="tr_bq">
An important further source of diversity is, in many cases, the influence of the<br />
research and professional interests of academic staff. While undergraduate programmes in mathematics, statistics and operational research are not generally expected to reach the<br />
frontiers of knowledge, it is a stimulating experience for a learner to be taught a subject by someone who is an active researcher or professional in the field. The choice of material presented in mathematics, statistics and operational research programmes, while mainly determined by its educational value, is nevertheless often influenced in detail by the research and professional interests of the academic staff.</blockquote>
When I was talking to a colleague about this, he told me that no one really believes that undergraduate students can not do research into mathematics, but what we can do is <a href="https://www.plymouth.ac.uk/your-university/teaching-and-learning/guidance-and-resources/research-informed-teaching">research informed teaching. </a><br />
This is consistent with the above quote from the subject benchmark. <br />

In the earlier course, they are given written notes, like a mini text book for the course. I do put my slides on Moodle. And now I have started taping the course with the new lecture capture system, which has been installed in some of the lecture rooms, here at Plymouth University.<br />
In this post, I discuss some of the issues, with this feedback from the students.<br />
<br />
I was an undergraduate student in the middle 80s and a graduate student in the early 90s. The lecturer would write on the board and we would copy that down. I can only remember one person who used computer made slides. He claimed he had some kind of shoulder problem, so he couldn't write on the board. I really enjoyed his lectures, but that was because they were on group theory. Essentially us students would copy from the board the notes.<br />
<br />
When I first presented some lectures at Liverpool, I was given some notes with a bit of theory in them and some examples. I would write them on the board and the students would copy them down. I did some small experiments with latex slides for a couple of weeks, but it was too much work to prepare. When I was a tutor at Glasgow for the second year physics students, I noticed that most lecturers were putting slides on Moodle.<br />
<br />
However, at Plymouth, for the first course, I was given a booklet of notes. It wasn't very clear what I was meant to do with it. The students would get the notes and then I would write them on the board as well. Now that I watched a couple of staff lecture, it is clearer what is happening. The lecturer, presents some examples and a bit of theory, in a similar manner to what is in the notes. But the notes are the definitive copy of the material. There is always some interactive part of the class, where a basic problem is set.<br />
<br />
Last year, I talked to teaching staff at Liverpool and Edinburgh. They are still presenting material in the traditional write on the board model.I was told, that some of the staff in the Mathematical Sciences Department at Liverpool, were told by students, that they prefer the black board methods over powerpoint.<br />
<br />
What I don't like about the use of the notes, is the presentation material is not always logically presented. The lectures have always been engaging, but in one I watched, the entire class had problems solving a very basic question.<br />
<br />
The course I am teaching has never had a course booklet, so I don't have time to write a book.<br />
I will try and write something based on the basic equations needed in the course.<br />
<br />

We are using a planetarium on campus for the lab sessions. Actually, it is called the Immersive Vision Theater. See the picture below: <br />

<br />
<br />
<br />
This is the first time. This course has been run, so we have no experience with using the planetarium for teaching. I did a quick literature search and found this paper:<br />
<a href="http://link.springer.com/article/10.1007%2Fs10956-014-9516-6">The Effect of Planetariums on Teaching Specific Astronomy Concept</a>s<br />
<br />
The paper uses a multiple choice test on groups of students, who did and did not, have access to the planetarium. They found that there was a statistical improvement in 3D thinking for the students who had access to a planetarium compared to those who were taught in a classroom.<br />
<br />
On reflection I will use some of the multiple choice questions coupled with the demonstrations in the planetarium.CraigMcNeilehttp://www.blogger.com/profile/00292137283015549566noreply@blogger.comtag:blogger.com,1999:blog-1805096721914791199.post-5808270040462657022016-02-02T14:23:00.000-08:002016-03-24T05:19:49.648-07:00Notes from a physics education meeting (UKPSF: K1, K2, K5)Just before Christmas, I attended a meeting in London about Physics<br />

The meeting was organized by the <a href="https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjU4JKdjtrKAhXCvRoKHSASD_0QFggfMAA&url=http%3A%2F%2Fwww.iop.org%2Factivity%2Fgroups%2Fsubject%2Fhed%2F&usg=AFQjCNFJB83RpxEbN7lNDPZ6NmFJMmcBsQ&sig2=BIFUef6RsFTCzK_m0RbbqQ&bvm=bv.113034660,d.d24">PhysicsEducation group of the IOP. </a> The meeting was really about people<br />
trying to start to do research into Physics education, rather than to<br />
disseminate the results for people trying to teach. Do I intend to do<br />
Physics Education research at the moment? Well no, but I still enjoyed<br />
the meeting. Part of the reason I am not interested is that I need to<br />
do more background reading on research methods.<br />
<br />
During the questions and the few lectures, there were some discussions<br />
about traditional physics research versus physics education research.<br />
There was very little jargon from the PGCAP / HEA communities. I don't<br />
think I remember anyone talking too much about "reflection" and peer<br />
learning, and the other silver bullets loved by the HEA people.<br />
<br />
The starting talk was a discussion of what PER is? The first thing<br />
suggested was to write a question. The example given was whether there are<br />
gender differences in problems solving. However, there was some<br />
discussion about whether the first thing would be to write down<br />
the motivation for the question.<br />
<br />
There was a lot of discussion about trying to understand what the<br />
students were thinking There was some discussion of research methodologies. Do we need to use<br />
techniques from social sciences? <br />
<br />
In a comment, someone noted that Nottingham Universities once had a<br />
time with no exams in the 4th year. One guy claimed the students were<br />
much better as PhD students.<br />
<br />
Many people have used open book exams. There was a feeling that the<br />
students found them harder than normal exams.<br />
<br />
There was an idea called<a href="https://en.wikipedia.org/wiki/Triangulation_%28social_science%29"> triangulation. </a><br />
This is where more than one technique is used to assess a method. <br />
<br />
Also Ross mentioned a technique where students articulated what they<br />
did. Someone noted that this may actually change what may be measured.<br />
<br />
<br />
One person noted that, in the past when students worked on<br />
Fermi problems, the students would actually try to do the<br />
back of the envelope calculations. However, students will<br />
now try to estimate problems, such as "how many piano tuners<br />
are needed in Sydney?", by firing up google. (Actually this is what<br />
I do as well). As one person pointed out, this is actually a<br />
legitimate technique. A textbook was recommended<br />
College Physics by <a href="http://www.amazon.co.uk/College-Physics-Eugenia-Etkina/dp/0321715357/ref=sr_1_8?s=books&ie=UTF8&qid=1454451345&sr=1-8&keywords=College+physics">Eugena Ethina.</a> However, this turned out to be very<br />
expensive at 160 pounds.<br />
<br />
Some PER journals:<br />
<br />
European Journal Of Physics<br />
American Journal of Physics<br />
Physical Review Special edition<br />
<br />
There will be a new journal for physics education. The journal is<br />
revived from an old HEA journal. New directions will be<br />
restarted. It will be a positive experience, where the referees help<br />
the authors improve the paper, rather than just reject.<br />
<br />
What I learned from the meeting was that there are social sciences techniques for evaluating teaching techniques. I have purchased a couple of books, so I can learn about them. <br />

I got the original notes from the people who taught it four years ago. I am now adding a summary at the beginning and a summary at the end. I have added a few more questions in the notes. I thought I was utilizing some of the ideas from <a href="http://www.compadre.org/per/">Physics Education research. </a><br />
<br />
But now when I look at the results, my notes are starting to look like one of those big American text books on physics, such as <a href="http://www.amazon.co.uk/University-Physics-Modern-Hugh-Young/dp/1292100311/ref=sr_1_1?s=books&ie=UTF8&qid=1454274994&sr=1-1&keywords=young+physics">University Physics with Modern Physics </a>by Young et al. There is always a summary of basic equations, and little boxes with equations. These textbooks essentially contain all topics in an introductory course in Physics. I don't remember using that kind of text book, when I was a undergraduate student at Imperial College. Each lecture would recommend different more specialized textbooks, such on waves.<br />
<br />
It could be that the British way of using books is used, because the level of the courses was higher, so a large comprehensive book didn't contain enough information. My understanding is that, these big introductory courses were unpopular with the students.

He found that the most useful thing that the student had learned on their mathematics degree was a familiarity with the spreadsheet package Excel. I had the same experience.<br />
<br />
We do teach some Excel to the students, but because the staff don't like to use it, apart from entering marks, we don't perhaps teach as much as we should. Excel is really rubbish at plotting histograms, so that biases me against it. Also a useful data analysis package only existed for Windows.<br />
<br />
My colleagues suggested that we look into getting the students to take some exam to get Excel certification. Now that I have done a quick web search, I see that Microsoft actually off a number of <a href="https://www.microsoft.com/en-gb/learning/default.aspx">certification exams. </a> I have seen a University in the USA off certification in the SAS statistical language, but we don't use it because it is expensive. It is not clear to me that a University department should be also be certifying students in Excel. It might be hard to organize. It is not clear how to pay for the student's exam. Also the exams are taken at special places.<br />

The subject is on electrostatics and a starting to look at currents in electricity. So the first example is rubbing amber and it becoming charged.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://www.newtonsapple.org.uk/wp-content/uploads/2013/06/rubbing-amber-with-fur.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://www.newtonsapple.org.uk/wp-content/uploads/2013/06/rubbing-amber-with-fur.jpg" height="320" width="293" /></a></div>
<br />
This was know to ancient Greeks. This is a good way to introduce charge. However, I don't fully understand the mechanism, behind how the charge is separated. The mechanism is not discussed in any standard textbooks. It looks as though the physics is called: <a href="https://en.wikipedia.org/wiki/Triboelectric_effect"><b>triboelectric effect. </b> </a><br />
This is what the great Feynman says:<br />
<br />
<blockquote class="tr_bq">
Yet in all our long and involved discussion we have never explained why it is that<br />
when we rub a piece of amber we get a charge on it. So you see, this physics of ours<br />
is a lot of fakery -- we start out with the phenomena of lodestone and amber, <br />
and we end up not understanding either of them very well.</blockquote>
To really understand the basic physics of static electricity requires that the students know about atoms. I will briefly discuss atoms and things later on in the course, so now is probably not a good time to add much more detail.<br />
<br />
When I read a few chapters of <a href="http://www.amazon.co.uk/Five-Easy-Lessons-Strategies-Educational/dp/0805387021/ref=sr_1_1?s=books&ie=UTF8&qid=1454155141&sr=1-1&keywords=five+easy+lessons">Five easy lessons</a> by Knight, I see that from Physics Education Research, that many students really only learn the algorithmic nature of the electricity problems. They don't really understand physical principles, such as charge conservation. Also, from the<br />
research quoted in the book -- they don't really understand important things such that an insulator can get charged. <br />
<br />
When I was <a href="http://www.compadre.org/per/per_reviews/volume1.cfm">reading a paper called Matter and Interactions</a> by Chabay et al<b><i>. </i></b>they claim that the syllabus needs to be made more modern. And that the atomic theory should be used more. They have written a text book, where they use a more modern approach to physics and not this is complementary to physics education research. <br />

(UKPSF A1 A2 K1)I am just starting to teach a foundation year module called Physics II to the students. This is the second time I taught the course. So here are my thoughts on improvements.<br />
<br />
<ul>
<li>I would like to add more applications. I have been reading about batteries and more about medical application of radiation. These are always good for motivation. With my better understanding of cognitive load theory, I need to make sure that the applications are clearly separate from core course material.</li>
<li>I showed a few videos last time. I think it is better to download the videos from youtube if that is possible. The adverts and banners get in the way. I like the videos because they replace physics demonstrations, that we don't have. Also in the end of the course I used explicit questions, to focus their attention on the explicit thing I wanted them to think about.</li>
<li>The lecture motes had some inbuilt exercises. I need to add more particularly with the new 2 hour long lectures.</li>
<li>The students seemed to like the two mock tests that I ran. I provided solutions, but I could make the solutions more useful, by linking back to lecture material. Also I will add instructions on how to use the feedback in the self marking.</li>
<li>There is no white board in the lecture theatre, so I am going to have to use the visualizer, when I write the odd solution to problems.</li>
</ul>
I wonder if there is a literature on how to effectively use videos in lectures.<br />
<br />
I am sure that more things will occur to me as time progresses....

I didn't make a presentation, but just did a basic "show and tell."
The main comments I got were about integration with online course management systems such as <a href="https://moodle.org/">moodle</a> What I was told was that there is a common system to integrate different educational technologies together called <a href="http://scorm.com/">SCORM.</a> When I had a quick look at the web page for SCORM, I see it was invented in the USA, because of the many different educational technologies. The technology education market is huge and worth many billions of dollars. This explains why the government got involved in the creation of standards to get educational software to talk together. It also stops "vendor lock in."<br />
<br />
SCORM is something the technology people at the University would have to install, so that may take sometime. Interestingly enough the MapleTA system I use doesn't use SCORM to talk to Moodle.<br />
<br />
One person (a national teaching fellow), at the meeting, told me that she used a similar (non free system) to check that students had watched the videos, when she was teaching using the flipped classroom. This system integrated with Moodle via SCORM. I now see that a SCORM plugin is already installed in Moodle at Plymouth University.<br />
<br />
Why is this important for students? It makes it easier for the students to log into the system, because with SCORM, they could in principle use the single sign in to login.

<a href="http://www.sigma-network.ac.uk/calendar/beyond-mathcentre-electronic-resources-for-maths-assessment-and-support/">Beyond mathcentre: electronic resources for maths assessment and support </a> at the University of South Wales in Cardiff. This is part of the Sigma network, which is a network of lectures in Mathematics based in the South West of England.<br />
<br />
The first talk was by <i>Embedding computer-aided assessment and other electronic resources in the curriculum</i>, <a href="http://www.brunel.ac.uk/%7Emastmmg/" target="_blank">Martin Greenhow</a> from Brunel University. He had his own computer aided assessment system. It didn't use a computer algebra system as a back end, so he was using multiple choice questions. He thought that the multiple choice questions was good for the students. It was better motivation, if a student gets 2/10 on a multiple choice than getting 0/10 on a mathematical quiz.<br />
He spent a lot of time making the mathematical problems relevant. For example his system was used for teaching nurses how to measure out the correct amount of medicine. He had learned about the correct doses of various pills. This<a href="http://www.ncbi.nlm.nih.gov/books/NBK2656/"> report g</a>ives information about errors about medication. It claims that 7000 deaths occur annually, because of medication problems. Some of these problems are not due to arithmetic issues, but miss-identification of the doctors written notes.<br />
<br />
Martin was a big believer in using SVG (scalable vector graphics) for figures, because the students could easily resize them. This is useful for students who have vision or reading problems. Like everyone else he was using, or planning to use, <a href="https://www.mathjax.org/">mathjax </a>for displaying mathematics.<br />
<br />
He found that the students really liked the detailed feedback he provided. He also tried to find the common errors that the students made and then he would provide detailed feedback to help them. He used the phrase mal-rules for mathematical mistakes the students were making. See <a href="http://onlinelibrary.wiley.com/doi/10.1207/s15516709cog1403_4/abstract">this paper </a>from a cognitive perspective.<br />
<br />
He talked to me about the entropy of questions. Also he mentioned the idea of <a href="https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=0ahUKEwj95qbRocfKAhXjtYMKHRYTBNMQFggqMAE&url=http%3A%2F%2Fmcs.open.ac.uk%2Fjhm3%2FOtherPapers%2FChrisSQuestionSpaces04.pdf&usg=AFQjCNF4zUSsRq7OgFvkP7IL2-WBYiQOYA&sig2=F5LnIoujHCYV6NvdohmaGg&bvm=bv.112454388,d.amc">question-space</a> from <a class="fl" href="https://www.google.co.uk/search?biw=1203&bih=640&tbm=bks&q=inauthor:%22Chris+Sangwin%22&sa=X&ved=0ahUKEwj95qbRocfKAhXjtYMKHRYTBNMQ9AgIKDAA">Chris Sangwin </a><br />
to try to quantify the number of mistakes the students could make.<br />
<br />
Martin also used project students to help author questions and the feedback. Writing such detailed questions is a lot of work.<br />
<br />
He also seemed to claim that if a woman's name was used in a word question, then more female students would get the correct answer. So he designed the questions to take into account diversity.<br />
<br />
He liked the idea of computer aided assessment and exams. The students relaxed when they saw the exam questions, because they had been trained on the algebra system. If they had done no work, or cheated on the assessment systems, then they got a low mark on the exam.<br />
<br />
So what did I learn from it. Now that I see what people are doing, they are clearly in the lead in providing detailed feedback to students. The students like the feedback, when it is tailored to their<br />
mistakes. I will have to look again at the feedback possibilities in the commercial computer algebra system I use (<a href="http://www.maplesoft.com/products/mapleta/">MapleTA</a>). <br />
<br />

I am not really set up to use pod casting, where I write mathematics on a tablet. See this example by a colleague.<br />
<br />
<br />
<br />
One of the local PGCAP people told me they thought Martin stopped video and then asked the students to do some questions. This turned out to be a misunderstanding.<br />
<br />
It turned out that it is possible to embed questions into videos. See <a href="https://docs.google.com/document/d/1U9zcjXnZY4KIxmRjJ8gPZPXYzoqUP6qRsqz4mZ19Vrk/edit">this example </a>I have made<br />
using <a href="https://edpuzzle.com/">edpuzzle. </a><br />
<br />
I really liked what I saw of edpuzzle. There is an equation editor, which seems to use latex to create the questions. There is only the possibility of making multiple choice questions, but that should be fine. you.<br />
<br />
It was easy to:<br />
<ul>
<li>crop the video (a similar system to the editor in youtube)</li>
<li>add a question at a point in the time line of the video.</li>
<li>add audio commentary at various points in the timeline</li>
</ul>
The main disadvantage is that the students must log into the system with a google email or another type of account. This is done so that the student's mark's can be recorded. This is good, because it lets me see who has taken the test. But it is bad, because some of the students may not want to register.<br />
<br />
It is a useful tool, if I want to comment on a video made by another person. The ability to add audio clips is very useful, because I may want to make a comparison between the video and something I have covered in the class.<br />
<br />

The event was aimed at teachers who teach mathematics at A-level. In the past, I have taught an introductory course on calculus and complex numbers. It is never very clear what knowledge of mathematics the students have when they passed A-level mathematics. Indeed I went to one course in Birmingham, where the consus views of the new lecturers present was that you could not assume any mathematics knowledge for students coming into University with A level mathematics.<br />
<br />
The A-level mathematics courses are being redesigned. The module system is being scrapped. This is where the A-level is broken into modules and the students have to pass each module. There is an exam at the end of maybe each semester. In the new system, the modules are scrapped and the content is taught linearly. This can only be a good thing, because it seems that students sometimes assume that they can forget material once they pass the module, rather than build up on top of material.<br />
<br />
The new syllabus had an amazing amount of stuff in it. It would be great, if we could get more students with further mathematics.<br />
<br />
It wasn't totally clear when the new A level will be taught, but it could be that we don't see any new students until 2019. We will have to wait and see whether the students are better prepared. It was also interesting to get an insight into what the teachers were thinking. <br />
<br />
How does it help my teaching? It would be good, if we could start a course by revising reminding them about material we have previously taught them. This is slightly complicated, because there are four different exam boards.CraigMcNeilehttp://www.blogger.com/profile/00292137283015549566noreply@blogger.com
