OER Lecture Materials - So Far They Don't Impress Me Much!

I mentioned a while back that the dept. is migrating to using Open Educational Resources (OER) texts this coming Fall. I'm all for it because the texts are quite reasonable and it will save the students a lot of money when their textbooks are free.

I'll be teaching two different courses that use to different OER texts out of OpenStax. I'm so freaking glad that I looked at the so-called lecture materials that accompanied each of these texts early this month because I would have been in a panic mode if I were to start preparing just 2 weeks before classes start! This is because the PowerPoint lecture materials are nothing more than a collection of the figures from the texts. That's it!

My first reaction when I first opened them was "What the......?"

Then blood drained from my face because I realized that I had to produce the lecture notes from scratch for both classes! And I had 3 weeks to do that!

Now you could tell me that I can just copy the lecture presentations from the same course that I had taught previously. True, but I want to stick with the content of the texts that the students will be using, especially in going over the same examples, using the same notations and format, etc. I want to use the same symbols for the various quantities that we will be using, so that the lecture presentation is consistent with the text. So I can't just copy old lecture notes verbatim, and I certain have to change the examples to match the examples in the text.

But even that is not that easy. My PowerPoint presentations often have links, animation, and other interactive stuff that are specific to that text and course. We were using Pearson's Mastering Physics, and I used quite a number of their videos to illustrate various physics principles. I can't use that anymore because those are copyrighted to Pearson and to be used only with their material. This means that I have to redo the animation and find new videos to include in the lecture presentation.

I did a Google search online to see if there are lecture notes using these two textbooks. There are, but all the ones that I have encountered so far are in PDF, meaning that I could not modify them to suit my needs.

Ugh! This semester is going to be a nightmare! I hate not already be prepared by this time!

This is why you haven't seen a lot of blog posts from me these past few weeks. Sigh....
