OCR Computer Science A Level H446 based on Heathcote chapters

Author rank 20
Author: Colin Hamilton at William Ellis School
This course is based on the Heathcote A level Computing book (PG Online) written for OCR H446.

It countains 3 SPAs, which encourage students to really understand and evaluate a topic. To run an SPA in the classroom:
  1. Assign as normal.
  2. When students are ready, click the Start button in the Assignments list. Make sure you have enough time; an SPA cannot be stopped half way through. You can adjust the time allowed at the start point, but not after.
  3. Students will work through a 3-step process of write|judge|vote.
  4. When they are finished, you can access their answers from the Assignments list. Answers are ranked by the process but these ranks do not correlate direct to grades. 


Structured Peer Assessment intro for students on Vimeo (also on YouTube here).

Show this 2:15 orientation video to your students before they start.

After the exercise, find the responses listed at Assignments Tab->Results->Short text responses  

SPAs work best with open questions that invite evaluation and explanation. They are not suitable for testing rote-learned facts. When assigning, please draw students' attention to the judgement criterion: the teaching point is actually subtly encoded in this.
