Student access a different approach
Last year we wrote the study guide which is basically an online textbook with hundreds of animations. Since then I have been making it even more interactive by adding hundreds of multiple choice questions interspersed in the text. They are not typical IB paper 1 questions they are specifically written to ensure that a student has understood the main point of the text. This is particularly good for revision but could be used as the basis for a teacher led course. I use the activities for my student centred course and keep the interactive textbook for revision purposes, it is therefore convenient to keep it separate from the weekly assignments. Students can access the textbook without me setting it but then I wouldn't be able to track their progress. So I have made a new group called Interactive textbook. The whole textbook is assigned in this group so student can easily navigate and choose the topic they wish to revise. If they do this their efforts are not left unnoticed since I can track their activity on my dashboard.
Note: These pages are set up differently to the usual mc quizzes. Students can reveal answers question by question instead of at the end. They also have the possibility to save and come back to finish.
