Feedback from the S207 revision day

Visible to anyone in the world

My staff tutor for S207, Sally Jordan, attended the session, and she kindly provided the following comments on the session:

I know that planning was a bit of an issue – very many thanks for all you had done and for coming so well prepared. I felt that the balance of activities on the day was good.

There was a lovely friendly atmosphere throughout. I felt that you did the right thing in rearranging the furniture, but I was slightly surprised to see that the rearrangement gave us two rows – in such an otherwise informal setting, it would have seemed very strange had some of the students sat on a row in front of the others. I’d be interested to know what seating arrangements you generally prefer for tutorials – I quite like getting students working in groups around small tables, though I know that can be a problem if you’re making lots of use of Powerpoint. I appreciated the name labels and the fact that we all introduced ourselves at the beginning.

The dayschool started nicely on time (and ran to time all day) and I liked the way the agenda was shared with the group. I might have asked right at the beginning if there was anything else they’d like to cover (this sort-of happened – there was a pause and the students seemed very happy with what you had planned). I’d also normally suggest sending the tutorial plan to the students beforehand, either by group email or by posting to the tutor group forums – that gives them chance to add topics for discussion. However, I do appreciate that there would have been several difficulties with this approach on this occasion, and it is also perhaps less appropriate for a revision session than for other tutorials.  The students did get a choice later in the day, which was lovely, and they had the confidence to ask for an explanation of lenses (which you and Robert between you explained quite well).

The first activity (the matching of terms to their definitions) was lovely and getting students to attempt to write a definition first was very sensible and worked well. I’ve always considered this part of the S207 exam to be the most difficult and I haven’t changed my mind as a result of yesterday!


From here we moved onto the discussion of ‘silly mistakes’. I thought this was a good idea, though I might has included fewer examples relating to vector notation and more other things (you could perhaps have given an answer to an incorrect number of sig figs or with incorrect units? – or is that more appropriate for S104 than S207?).

After the summary of Book 2 topics, we moved into the first set of examples and I think these worked extremely effectively to build the students’ confidence in their ability to answer exam questions. With you, Robert, Alan and me all having an opinion as to the best way of tackling the problems I was slightly anxious that the students would be confused, but actually I think these three students will have benefitted from seeing a variety of approaches.

After lunch and Robert’s introduction to the S207 exam and the discussion of  exam and revision strategy,  I really liked the fact that you gave the students the choice of either returning to the examples in your Powerpoint or working through an old exam paper -  and didn’t they do the exam paper well!  After giving them a sensible length of time, you and Robert discussed the questions with them – lovely.

All in all then, an excellent day. You, Robert and Alan have different but complementary styles and your collective knowledge of the subject matter and experience of teaching shone through!

S104 tutorial - book 7 and revision

Visible to anyone in the world
Members of the group have asked for some time during the next tutorial on revision and exam preparation. I will also need to cover some Book 7 "Quarks to quasars" content.

The tutorial is planned for fairly early in the the book 7 work, so I will focus on atomic and nuclear structure. We have touched on these topics earlier in S104, so there should be a good degree of familiarity.

I looked at an old TMA and decided to base much of the session on two topics: energy levels, spectra and hydrogen-like ions, and on nuclear reactions and decays. I prepared a Word document for me to use, with the questions and answer notes, and with some illustrative material from S104 and S282. 

In case we get through that fairly quickly, I printed off some handouts for my Hubble expansion activity. I devised this activity at the start of S104, as one of the 'offical' tutorial resources.  It would be useful if we can do this activity, because it links very well with the cosmology online discussion I have just initiated on the forum.

I then worked though the S104 specimen exam paper to familiarise myself with the contents. I will recommend that in the exam students do the Part B question first (presumably a graph), then the computer-marked Part A questions. The two longer questions from Part C should be left until last. I think it should be reasonable for people to aim to get through the exam in around two hours. After doing Part B and Part A I suspect most people will have reached or be close to their 40% pass mark.

I also printed out the short questions from an old S103 end of Course Assessment. We can work through some of these in the tutorial.

Elluminate for Astronomy exam resit tutorial

Visible to anyone in the world
Edited by Dave Edwards, Monday 8 April 2013 at 10:16

I have been asked to provide two one-hour long Elluminate sessions for students resitting their S282 'Astronomy' exam.

I will follow my original proposal for the task. This was a skill based first session:

Revision skills
Exam technique
Maths skills
And a summary of key physical principles.

My intention was to build a discussion oriented session. As students may not have started revision I do not think quizzes are appropriate. However, some of the examples will lend themselves to asking students to spend a few minutes looking for information or solving problems.

I drafted an outline plan on a sheet of paper. then I started to work on PowerPoint, reusing an introductory screen on using Elluminate.

I used a pdf copy of a module book to extract one page and annotate that with my Tablet PC to illustrate the idea of using diagrams and annotating the module book. this was difficult to do - I had trouble extracting a copy of the page from the huge book. I found a copy of the appropriate chapter only, and managed to delete the other pages.

I also wanted to illustrate the use of spray diagrams. I used a chapter summary section to prepare a hand written spray diagram. I then scanned this in, rotated it and inserted it into the PowerPoint. The quality was poor. I tried to improve the legibility of the diagram but did not manage to find an appropriate tool. It would be too time-consuming to prepare the diagram electronically, so I decided to accept the slide as it stood.

I used an extract from an old exam question to create an exercise on writing. Simlarly for a maths skills example I used an old TMA question part, and the excellent example answer I had supplied to students.

To help me discuss the the revision period I took a hand-drawn diagram from an S282 handout I have often provided to students.

Then I prepared a list of key ideas (extending over four slides)by skimming through the book.

While working through the preparation I kept in mind the need to have dark colours and large text and images so maximise legibility in Elluminate.

I also adapted the first screen to place on the Elluminate site, in the hope that I can encourage students to use their mircophone.


All this work took about six hours.
