Feedback

Part way through the module, and again at the end of it, I give over part of a class to anonymous feedback: what is working, what is not, and anything else you want to tell me. Every round is kept on this page, newest first, exactly as it was written and with my response to it, so the record builds up year on year.

I publish it for two reasons. The first is that you can see the feedback is read and acted on rather than collected and filed. The second is that the comments tell you what the people who sat in your seat found hard, which is useful when you are working out how to study.

Responses appear as they were submitted, including the typos. A few are cut short because the polling tool limits how much can be typed into one answer.

Mid-module feedback, 2026/27

Collected in class on 23 October 2026, in week 4 of the module. Fifty-seven of you answered the first question, 39 the second and 17 the third. Thank you.

What works

Forty-seven of the 73 comments on what works name the activities: the games keep the room awake, and several of you say that playing a game first and meeting the theory afterwards helps with the theory. Twenty-eight mention the website, the notes, the worked solutions or the video walkthroughs. The enthusiasm, the questions in class and the bribentives all get a mention too. None of that is changing.

What does not work

One theme dominates, and it is a fair one. Thirty of the 47 comments on what has not worked are about the mathematical content: the definitions, the theorems and the notation in the notes, how much of them appears in class, and how clearly the game we have just played connects to them. Several of you put it as "sometimes it feels like we just play games", and several more said that the subgame perfection class, where we played the Traitors and then wrote the centipede game out on the board, was a good mix.

Twelve comments ask for more exam-style work in class and a clearer statement of which proofs and definitions are examinable. Six are about the games themselves, mostly that the rules are not clear enough when you play in pairs. Five ask for resources: the slides, a version of the notes you can download and annotate, more past papers, and better handwriting in the videos. Three are about the room, which I will get back to below.

What I am doing

  1. Every class will end on the notes. Each slide carries the numbered section of the textbook it is reading, and the last slide will summarise them into one table, marks what is examinable, and says what to read before the next class.
  2. More of each class will be spent turning the game into notation, the way the subgame perfection class did.
  3. When an examinable theorem comes up, I will say so in class and point at the list of examinable theorems.
  4. The slide decks are on the site already, linked at the foot of every topic page, so you can read them before class and keep them afterwards. I will not be uploading the versions I annotate live.
  5. I will add a summary of rules of each game slide to stay on screen while you play it, so you are not working from memory once you are in pairs.
  6. The notes are linked as a PDF you can download and annotate, at the foot of every topic page.
  7. Last year's exam paper is on the Assessment page.

Single comments worth answering

Most of what follows was said by one person, which does not make it less worth answering.

If you could sometimes chuck up a definition or a theorem on the slides.

Every slide now names the numbered section of the notes it is reading, and the last slide of each class gathers them into one table.

It is unclear what I am meant to be taking away from each lecture. Perhaps a speedy summary would help?

That same closing slide is the summary, and it ends with what to read before the next class.

You have mentioned some topics on the website are not in the exam, can you mention which ones are not?

The schedule is the examinable list: if a topic is not on it, it is not in the exam. The Assessment page lists the theorems whose proofs you need on top of that.

Is there any way of downloading the notes to a device so I can annotate?

Yes. The whole textbook is available as one PDF, linked at the foot of every topic page. One warning: the PDF is a snapshot, so any typos and small mistakes in it stay in it. I fix those in the web version as they are found, so check there if something looks wrong.

Please can you upload the PowerPoints used in class.

They are already on the site, linked from every topic page, so you can read a deck before class as well as after.

Any more past exams available from previous years?

Last year's paper is now on the Assessment page.

Maybe more quiz questions, the short form ones at the end of lectures.

I will keep this in mind. I had intended for the quizzes to be simple things for you to do if you had 5 minutes but they did work well during the traitors session. When we have time I will do a quizz in class.

Could you try making notes in the notes app with your pen? A scrolling board is easier to follow than an infinite whiteboard.

A fair point. I will run the next example class that way.

I have not done discrete maths before and the notation at the start did not make much sense.

You were not the only one. Every symbol we use is defined in chapter 2 of the notes, utility included, before anything is built on it. I hope you feel like you can ask me if you're ever unsure.

The handwriting in the videos is like reading ancient greek: beautiful but I do not know what it means.

Fair. I will try and do better next time.

I personally dislike 2.26 because the tables are an odd shape. I think it is unclear how many people are meant to fit on a table which discourages people from making space for others.

I should admit that I like the room. It is one of the few teaching spaces where everybody can see everybody else and where a game can spread across the floor, which is most of why this module is taught the way it is. That does not make it a good room to write in, and the tables really are an odd shape. Somebody also asked about the temperature in there, which is a fair question.

I like your approach to class q/a in the way that each response is genuinely appreciated even if it's wrong, it encourages engagement.

Thank you, and thank you to everybody who answers in class. A wrong answer out loud is worth more than a right one kept quiet: it tells me exactly where to go next, and the person who offers it has done the whole room a favour. That is not changing, so keep putting your hand up.

Honeydew melon, Lidl bakery items, KitKats and fruit have all been proposed as bribentives. Noted.

The balance I am not changing is the order: activity first, theory second. The games are not a break from the content, they are the thing the content is about, and the feedback above is what tells me the join needs to be tighter.
