Last Session

📥  Uncategorized

Finished testing the fixes made to questions in response to 1st year feedback. I also managed to fix a few errors in the thermodynamics questions using the answer booklet. As this is probably my last session I've uploaded all my PHP files and XML files, and have also zipped my public_html folder and added it to Moodle.

I've enjoyed my time on the project and it has been valuable experience doing some programming - and helping next year's undergraduates with their maths skills. Before I leave permanently I have a few suggestions if the project continues next year:

Peer review of questions: getting everyone to test questions as we go would reduce obvious errors like missing hints/feedback/typos. It was a lot easier modifying mistakes for recent questions than coming back to something that was done 6 months ago.

MathJax: developing a function that transforms a mathematical string e.g. 5.5 mol^-1 into the correct MathJax would be very helpful. A fair amount of my time was spent debugging errors in MathJax syntax, along with PHP syntax errors caused by the % wildcard.

PHP templates: I found my PHP template for a question immensely useful as it meant all I had to do was modify one function and a few variables, rather than manually editing XML in fprintf calls. It would be good to use something like this as standard as it would be much easier to understand code written by different people.

Spent the day editing some of the questions I have already done, I was unsure as to what I should do for some of the questions however.

Fixed the errors highlighted by the feedback, and reuploaded the relevant php files. Also finished the word document, containing the php file name, XML file name, and the text from one of the questions.

Tidied up questions according to 1st year feedback - a lot of the comments such as missing hints were due to incorrect configuration of a quiz so it appeared worse than it was. Next week will finish off the tidy-up by verifying the fixes have worked properly.

Continued on with thermodynamics questions. Next week will likely involve more of the same, and testing the previously completed questions against the answer booklet.

Tidied up the categories already uploaded, and recreated test quizzes of the questions. Came across an error in the kinetics question, which used rounded values to create an incorrect answer. I will attempt to fix this in the next session, and list the questions I've previously coded.

Completed two more kinetics questions that work very well, have also almost completed a third to do with half lives, sadly though I got kicked out of 3S and the computers in the library seem to be struggling with what I need, thankfully though I did complete my 3 hours before being removed.

Finished a question on the Arrhenius equation, had multiple difficulties with it so sadly couldnt complete as much as i wanted to today.

Still ive set up the ground work for the next question in my kinetics category and this one should be a lot easier to put together.
