@mrlouieevans @MrTSci409 @olicav Benefits of visualiser over board:
1. Face the class - keep an eye on pupils
2. Can permanently store all of your 'board work' (use an exercise book) - great for revision
3. Pre-prepare & reveal diagrams like with PowerPoint*
4. Can show worksheets, exams annotation & pupil work

@mrlouieevans @MrTSci409 @olicav *but unlike powerpoint, encourages use of simplified hand-drawn diagrams of concepts which cannot be done as easily on PowerPoint. Obviously use pre-existing diagrams if you can't draw them better.

5. Use live-dual coding on pre-prepared / partially completed diagrams

@mrlouieevans @MrTSci409 @olicav 6. Cover up & reveal for quick & easy retrieval practice
7. Show practical experiments to the whole class without everyone getting up & crowding
8. Take videos of procedures & loop video during practice
9. Model exactly how to show working out/answer on a page identical to pupil

@mrlouieevans @MrTSci409 @olicav 10. Answering questions live while feeding back automatically gives pupils as much time to correct their answers as it takes you to write them in.
11. Can clearly see you using a ruler/scalpel/paintbrush - any specific equipment you use in your subject.

@mrlouieevans @MrTSci409 @olicav 12. Encourages more rapid questioning as you draw/annotate/write, because you are facing your pupils.
13. Pupils can see you thinking, reflecting & pointing to important parts of diagrams as you answer their questions. Makes for easier natural questioning & dialogue in classroom
