CHEM 351 PODCASTS

The aim is to create podcasts of important topics and concepts to act as supplements to the lecture materials in order to help students review and learn the subject matter.  Remember that the subject matter is very visual, and therefore they are probably best used with your lecture notes or the pages on the ORGANIC CHEMISTRY ONLINE materials.

I have experimented with live (in lecture recordings) and office recordings in an attempt to find a feasible and efficient process. This means the sound quality may vary as I walked around in lecture.

If there is topic you think you would like a podcast on, these please let me know. Try to give an outline of what you think it should cover rather than just a title.

Here is a list of / links to the CHEM 351 PODCASTS available to date :
