Recently my Higher pupils sat their Computing prelim. In previous years I have gone through the marking scheme question by question, describing the ‘best answer’ where possible and highlighting which my students answered a particular question well. Unfortunately their peers rarely see these answers, so have to rely on what I say or put on the board.
This year as I marked the prelim I created a spreadsheet showing how many marks each candidate gained for each question (using the CloudOn service for iPad). I do this to help me highlight areas of development when discussing prelim performance with individual students, but this year used it to help create a document the whole class could use:
Part of the document, shared with students via our Edmodo group
The document replaced the marking scheme and allowed them to see the ‘best answer’ as written by their peers. There was one occasion where no student managed to achieve full marks for a particular question so I selected the best answer from the class and added some suggestions for improvement.
It was very easy to create using the Pages app for iPad and, although a little time-consuming on my part, took as long as going through that section of the prelim with the class. The advantage here is that I know all pupils have a permanent and consistent revision aid and I can use it when working with individual pupils on their areas of development. I also hope to use it next year to prepare students for their prelims by getting them to assess other student answers.
I entered the questions into the Pages app first, then used my spreadsheet to identify which student answer to add into the document. Taking photographs of their written answer using the iPad rear camera was so simple thanks to the ‘tap to focus’ feature and I was then able to crop the image quickly in Pages. The document auto-saves, which was very useful later in the process as the iPad ran out of memory a few times and crashed the Pages app. It caused a nervous moment the first time it happened but, once I was confident no information had been lost from my document, I put up with the inconvenience until all questions were associated with an image of a pupil answer.
Exporting the document from Pages as a PDF file was a straight-forward process, however the file size was a whopping 40MB! The file can be sent to a variety of apps as a Pages file, PDF or Word document. Uploading that size of document from a home Internet connection takes a long time, especially galling when I compressed the file on a desktop PC to 1.4MB using Adobe Acrobat. If anyone has worked out how to compress PDF files on the iPad I’d love to hear from you.
Once complete I shared the document with the class via Edmodo. I immediately made use of it by setting homework with similar questions. The average score in that homework was over 30% higher than their prelim score. In a few cases it was over 50% up! Obviously you have to take into account the fact they had access to their textbooks and the Internet while completing the homework task, but I feel that this type of document has definite value in improving student attainment.
