The presentations themselves contain minimal information as they are intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file for an idea of the aesthetic and level of detail in the presentation.
I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.
**These presentations are based on the IB Biology Course Guide and do not follow any textbook
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
