Anyone has any comments on the exercises/ questions posted on Khan Academy webpage?

Will students in Hong Kong benefit from doing these exercises?

As there is no videos for Geography, I just browse some of the related topics under "Biology", e.g. Photosynthesis. In my opinion, I think that these videos are useful when teaching concepts which involves:
ReplyDelete1. "step-by-step procedures/ flow charts", e.g. nitrogen cycle, carbon cycle, photosynthesis, weathering, water cycle
2. lots of "annotated diagram" for better understanding, e.g. formation of coastal and fluvial landforms, seasons, plate movements, soil profiles
Benefits of students in Hong Kong:
1. More visual and audio enjoyment in class
2. Lessons become more interactive and interesting when compared with blackboard writing
3. Enhance students' understanding in some difficult concepts, e.g. soil profile and plate movements through animations
4. Students are able to draw "annotated diagrams" effectively (it's one of the requirements in the HKDSE examination)
