Chemistry: Challenges and Solutions

A video-based instructional series in chemistry with accompanying website for high school and college classes. 13 half-hour programs, online text, course guide, interactive lessons, historical timeline and periodic table.

Chemistry: Challenges and Solutions teaches general chemistry concepts using real-life challenges in energy, materials development, biochemistry, and the environment.

The course zeroes in on essential topics that are generally taught in introductory chemistry, providing a strong foundation for learners to pursue further study in science or a liberal-arts education. Videos include dramatic demonstrations of key principles, interviews with scientists who are doing current research related to these fields, animations, and clear explanations. Each video is hosted by a different working chemist – together, they show a diversity of chemistry professionals and the challenges chemistry is addressing for society. The on-line text covers key concepts with clear text and illustrations, while interactive labs provide simulations of chemical processes online.

Series produced in 2014 by the Harvard Smithsonian Center for Astrophysics. As of the time of publication, episodes stream at the Annenberg Learner website.

Teachers Pay Teachers is now TPT

Once upon a time there were Digital Video Discs (or was it Disks?) and/or Digital Versatile Discs. No more. Now there are DVDs. What do the apparent initials stand for? They don't stand for anything. The discs are simply DVDs.

I believe that once upon a time, there was Physics Education Technology. Now there is PhET.

I'm sure more examples abound. Now we can pour one out for Teachers Pay Teachers. The service isn't going away. It's now simply TPT. The initialism had been in common use for years, and the company's leaning into it.

The rebranding is not universally welcome in the physics teaching community. The American Association of Physics Teachers' official journal, The Physics Teacher, has been published since 1963, and is often referred to as TPT.

I do not foresee either institution changing their practices out of deference to the other. We've survived multiple meanings for ATM, CD, CRT, EMT, etc.. We'll power through this duplication.
