Zotero inserts the reference list and styles it with the “Bibliography” style (which has doubleline spacing), while the template uses the “References” style (which is more compact). If you manually apply the “References” style, it will get undone when Zotero refreshes the reference list.
Here is how I’ve fixed the reference list formatting, by modifying the styles.
That will change Zotero’s “Bibliography” style to match the correct style in the template. Importantly, that will make the reference list take up the correct amount of space, so you know how close you are to the page limit!
You can see more about the reasons for the dispute from UCU, and from Edinburgh’s own Staff Student Solidarity Network.
For me, one of the main reasons is the way that pay has been eroded since 2009 (which happens to be around the time I started working for the University of Edinburgh).
This chart will be familiar to colleagues in the School of Mathematics, since I stuck it up in our common room above the sink! It shows the starting salary for a Lecturer, and for a Reader (the next grade up), and how these have been increased each year by employers since 2009. I picked these job titles as examples, but the same pattern is true for other types of roles too.
The chart also shows what would have happened if employers increased the salaries each year to keep track with inflation (the RPI version of it):
The key things I take from this chart are:
So – pay has been gradually eroded over the past decade or so, to such an extent that university staff are now effectively demoted by one grade on the salary scale.
If all university staff were demoted by one grade overnight, I’m pretty sure there would be outrage! That’s what I feel looking at this data, showing that we’ve been demoted gradually over many years.
The current dispute is about the pay increase for 2022/23. UCU has asked for an increase of RPI+2% for that year, which would go only a little way to closing the gap. Employers have imposed an increase of 5% and refuse to discuss it any further.
A second reason for me taking part in the strike is to show my disappointment with senior management. I know I’m not alone in this – in the recent Staff Engagement Survey, just 23% of staff agreed with the statement “I have confidence in the university leadership”. In the College of Science and Engineering (where I work), it was just 12% of staff.
The dispute about pay is a national one, and our Principal, Peter Mathieson, has pointed to the affordability of pay increases across the university sector as a reason for not supporting inflationmatching pay rises for his staff.
I reached out personally to the Principal on 30th May to ask:
You point to how some institutions may be unable to afford a larger pay increase than the subinflationary one that has been imposed. What are you doing as a leader in the sector to resolve this? Our sector should be strong enough to support pay rises in line with inflation!
I’ve not asked permission to share his reply, so I won’t – but in essence it was: “what do you propose?” I found this shocking. I thought he was supposed to be providing the strategic leadership, in return for his £400k+ salary! It’s not even like this is a oneoff issue that could have caught management by surprise – as the chart shows, it’s a systemic issue. Why are management content to do nothing about this year after year?
Senior management have also turned down an opportunity to stop the strikes in week 2 of our semester. The local UCU branch offered to cancel the strikes in return for restoring pay that had been withheld from colleagues taking part in the marking and assessment boycott (and who are now being asked to complete the marking since the boycott has ended). The offer from UCU was refused by management. Meanwhile management are painting a different picture for students (emphasis mine):
Those words sound hollow to me, in light of management’s decision to refuse UCU’s offer on 18 September – which has the effect of knocking out 5 working days when colleagues could be getting on with teaching semester 1 courses and dealing with the backlog of marking.
If you’re a student, please let University management know what you think by emailing the Principal, Peter Mathieson (principal@ed.ac.uk) and/or VicePrincipal Students, Colm Harmon (Colm.Harmon@ed.ac.uk).
If you’re a colleague who’s not already in UCU, it’s never too late to join the union!
]]>Roles of eassessment in course design
Q27. How can formative eassessments improve students’ performance in later assessments?
Q28. How can regular summative eassessments support learning?
Q29. What are suitable roles for eassessment in formative and summative assessment?
Q30. To what extent does the timing and frequency of eassessments during a course affect student learning?
Q31. What are the relations between the mode of course instruction and students’ performance and activity in eassessment?
I’m sure that I’ve not explored the full potential of all the Moodle quiz options, but here are some examples of settings that I use in my Fundamentals of Algebra and Calculus course.
For the course materials within FAC, I have put all the feedback settings to the max, including the option to redo individual questions:
The “scores” on those quizzes really don’t matter for anything, and actually most students never even submit the whole quiz to be graded, since they can see the results questionbyquestion as they go through.
Each week there is an assessed quiz that contributes to the students’ grades (see below) – but before they can take that quiz, they need to score at least 80% on the week’s Practice Quiz.
For the Practice Quiz, students can have an unlimited number of attempts – but there is no way to replace individual questions. Instead, students need to complete the whole quiz and submit it to get their score at the end (as preparation for the way it will work in the assessed quiz).
Each week there is a “Final Test” quiz that contributes to the students’ grades. Scores of over 80% are a “Mastery” result, and students need to get at least 7 Mastery results across the 10 weeks to pass the course. The grading scheme is a bit more complicated than that; you can see the full details in my paper about the course design and my post about how to set it up in the Moodle gradebook.
Having the requirement to score at least 80% on the Practice Quiz (which typically has very similar tasks to the Final Test) means that students should be wellprepared to succeed.
The Final Test itself uses more restrictive settings to control when feedback is available, since I wanted to avoid having worked solutions circulating while other students have yet to complete the quiz. In particular, the “general feedback” (i.e., worked solution) and “right answer” are only available after the quiz is closed:
There is only 1 attempt allowed at this quiz, with a time limit of 90 minutes from when the quiz is opened. Students need to complete each week’s quiz by a regular deadline. However, if students don’t meet the Mastery threshold, there is a resit version that becomes available the next day (again, set up using the “restrict access” feature so that it only appears for students who need it).
As I mentioned, I’ve only scratched the surface of what’s possible with the Moodle quiz settings. I know other colleagues have set up quizzes where students can make multiple attempts, and the grade is based on the average of the attempts (so as to incentivise trying hard on the first attempt, but allowing for students to improve if they’re not happy with a bad first attempt). It’s also possible to set penalties within questions, so that you can use the interactive quiz mode (like the course materials example above): that allows students to redo an individual question if they’re not happy with the score, but possibly with a penalty (again, to encourage students to take the first attempt seriously).
]]>Our students have a “University User Name” (UUN) which is an S followed by a 7digit number (e.g. “S1234567”), which can be used to link different datasets together. I need to replace these identifiers with new IDs, so that the resulting datasets have no personal identifiers in them.
I’ve written a simple R script that can read in multiple .csv files, and replace the identifiers in a consistent way. It also produces a lookup table so that I can deanonymise the data if needed. But the main thing is that it produces new versions of all the .csv files with all personal identifiers removed!
]]>One approach to this is to ask proof comprehension questions after giving the proof, but I’ve also tried writing some sequences of questions that lead the students through the proof in a scaffolded/structured way.
Here’s a simple example, of a sketch proof of the Fundamental Theorem of Calculus:
Students can’t see the next part of the proof until they give an answer. Once they have submitted their answer, the next part is revealed:
I’ve used this approach in other places in the course, sometimes with more than one step.
The way to do this in Moodle is by having the quiz settings set to “Interactive with multiple tries”:Then using the little padlock symbols that appear at the righthand side between questions on the “Edit questions” page:
After clicking the padlock, it changes to locked to indicate that students must answer the first question to see the second:
I’ve not done any serious evaluation of this approach, but my intuition is that it’s a good way to direct students’ attention to certain parts of a proof and encourage them to be more active in their reading.
]]>All the Unit Tests are set up as Moodle quizzes, and I needed a way to compute the number of tests completed as Mastery level (and at Distinction level) for each student.
To make matters more complicated, there are 4 different versions of each Unit Test:
Each subsequent attempt replaces the result of previous ones – e.g. if a student with a Mastery result on the first attempt decides to take the Unit Test (Extra Resit) to try to get a Distinction, then they will lose the Mastery result if they do not reach the 80% threshold.
To set this up in the Moodle gradebook, I have given each of the variants an ID, with the pattern:
(where n is the week number).
Then I have added a calculated grade item called “Number of Mastery results”, with a complicated formula to determine this. It is the sum of 10 terms like this:
ceil([[W1FTRD]]/32)*floor([[W1FTRD]]/25.5)+(1ceil([[W1FTRD]]/32))*(ceil([[W1FTR2]]/32)*floor([[W1FTR2]]/25.5)+(1ceil([[W1FTR2]]/32))*floor(max([[W1FT]],[[W1FTR]])/25.5))
where this snippet computes the number of Mastery results in week 1 (i.e. it will return 0 or 1).
Note that the 25.5 appears throughout this expression because that is the threshold for 80% on these tests.
ceil([[W1FTRD]]/32)*floor([[W1FTRD]]/25.5)
means “if they took the Resit Diet version, then use their score on that to decide if they got a Mastery result”(1ceil([[W1FTRD]]/32))*(...)
means “if they didn’t take the Resit Diet version, then use their other scores to decide”This is all quite complicated, I know! It has grown up over time, as the FTR2 and FTRD versions were added after I first set up this approach.
Also, when I first implemented this, our version of Moodle did not support “if” statements – since the Moodle grade calculations can now make use of “if” statements, this calculation could be greatly simplified.
]]>This year I’m supervising three undergraduate projects, and I’ve asked them to use the APA style for referencing in their reports.
It took me a while to find a way of doing this in LaTeX that I was happy with, so to smooth the path for my students I shared this version of the project template, where I’d made all the necessary changes to implement APA style:
https://www.overleaf.com/read/yjkyzmpmkcdm
The key parts are as follows.
In the preamble:
% formatting of hyperlinks \usepackage{url} \usepackage{hyperref} \usepackage{xcolor} \hypersetup{ colorlinks, linkcolor={red!50!black}, citecolor={blue!50!black}, urlcolor={blue!80!black} } % Use biblatex for references  change style= as appropriate \usepackage[natbib=true,backend=biber,sorting=nyt,style=apa]{biblatex} \renewcommand*{\bibfont}{\fontsize{10}{12}\selectfont} % add your references to this file \addbibresource{references.bib}
At the end of the document:
\printbibliography{}
And make sure to add references.bib to your project, with all the bibtex references. I’ve found Mybib.com a really useful tool for this, though I mainly use Zotero as my reference manager (and this can import easily into Overleaf).
]]>This post is focused on the first of these. Developing students’ abilities to read proofs is something that is not often done explicitly – there may be an assumption that students will pick it up by osmosis. There is some research into how to help students to develop these abilities (e.g., Hodds et al.. 2014), and a key part of this is having a good way to measure students’ level of comprehension of a given proof.
MejiaRamos et al. (2012) give a framework for assessing proof comprehension, with 7 different types of questions that can be asked:
Local  Holistic 


You can see some more detail about these different categories in a recent talk by Pablo.
The framework is helpful when trying to write questions to assess students’ understanding of a given proof, as it gives ideas for different types of questions you can ask.
A few years ago, I used this framework to put together some multiplechoice proof comprehension questions for our Year 3 course, Honours Analysis.
My experience of these is that students found them quite hard – the mean score was around 75%, so they are not trivial for students to answer.

Based on that, here’s an easy way to take a screenshot as a PDF:
For the page I was saving, I found that setting the paper size to A2 gave good results. I also set Margins to “Custom” and made the page slightly narrower. I think you just need to play around with the page size, scaling and margins until you are happy.
I also used the developer tools window to tidy up the page a little, e.g. deleting some irrelevant navigation boxes, and instructoronly tools.

]]>4*(cos(pi/3)+i*sin(pi/3))
an answer of 4*(cos((1/3)*pi)+i*sin((1/3)*pi))
would be marked incorrect!
The issue was that:
I was using the EqualComAss answer test to check whether the student answer (ans1) was equal to the model answer (ta1), and this was failing in the cases above.
The solution I came up with is to add some code to the feedback variables box at the top of the PRT, to replace cos and sin with alternate versions so that Maxima can’t simplify the expressions to cartesian form. I can then use ev(…,simp) to make use of simplification when comparing the expressions:
form_ans1:subst([cos=COSINE, sin=SINE], ans1); form_ta1:subst([cos=COSINE, sin=SINE], ta1); proper_form:is(ev(expand(form_ans1form_ta1),simp)=0);
This will ensure that COSINE(pi/3) and COSINE((1/3)*pi) will cancel out, thanks to the simplification being turned on.
But since Maxima doesn’t know anything about COSINE, it can’t cancel out COSINE(pi/3) and COSINE(5pi/3) (as it would do with cos) if students give their answer with the wrong value for the principal argument.
It was then just a case of replacing the test for EqualComAss(ans1,ta1) in the PRT with a test that AlgEquiv(proper_form, true), and regrading. Out of ~160 attempts this picked up 8 students who deserved full marks!
Update (08/11/2021): One year on, and STACK now has a new feature which makes it easier to grade these answers correctly! The new EqualComAssRules answer test lets you add a list of different algebraic rules so that two answers should count as equivalent if they differ only by those rules – e.g. x and 1*x.
To fix this question, it’s enough to change the first PRT node to the following, using the “Test options” box to specify the list of algebraic rules:
ATEqualComAssRules(ans1, ta1, [ID_TRANS,NEG_TRANS,DIV_TRANS,INT_ARITH]);]]>
