Anyone have a GOOD gen chem lab on colligative properties?

Submitted by Cameron Gren / University of North Alabama on Thu, 07/11/2013 - 13:32
We do a freezing point depression experiment (naphthalene in cyclohexane from Beran), but it just doesn't work! We have cu down on the amount of solute, but the students just cannot obtain consistent data! I'm about ready to scrap it, but I would really like them to do SOMETHING with colligative properties in lab. Any suggestions would be most welcome!

Novel instructional methods for studying the chemistry of main group elements?

Submitted by BoB LeSuer / The College at Brockport, SUNY on Wed, 07/10/2013 - 13:57

I am looking for some suggestions on innovative strategies for introducing the chemistry of main group elements to students.  Our Inorganic Chemistry class is a pre-pchem lecture and lab and I'll be using the 5th edition of Miessler/Fischer/Tarr.  (And a big thank you goes out to the authors, who have finally accepted to include at least a little bit of redox chemistry in the text.)  My issue arises with Chapter 8 (and the like), which in my opinion boils down to "read these sections, memorize these facts, quiz Monday".

Howdy all,

Awesome time at the workshop this week.  We saw an abundance of awesome chemistry, inorganic related clothing.

Sapling Learning Online Homework

I am planning to incorporate Sapling Learning online homework in my Foundations of Inorgnaic Chemistry class and my Advanced Inorganic CHemistry class. I've not used this program before, and am on the steep side of the learning curve. If you have an established course that I can adapt, that would be great. Also, I will be authoring questions as I need. Id love to crowd-source authoring of questions so that I'mnot just relying on my own perspective. Thanks!

Symmetry or kinetics?

I teach a one-semester upper-division course where, as we all know, tough decisions need to be made.  I have always taught symmetry, but it has become apparent that our students enter their senior year weak in kinetics, so I am considering swapping out symmetry/group theory for a more advanced treatment of kinetics and mechanisms.  This pains me, because these two topics are are two of my favories.  Then again, so is everything else...

Thoughts?

Supplemental Instruction questions

Submitted by Joanne Stewart / Hope College on Wed, 06/05/2013 - 14:33

We are planning to pilot a Supplemental Instruction (SI) program in one of our general chemistry sections this fall (2013). We plan to use undergraduate supplemental instructors who will attend class and lead supplemental discussion sections for small groups of students. We are familiar with the literature on SI and we have some experience with PLTL, but we still are anxious about the logistics of setting this up.

Favorite Podcasts?

Thanks to everyone for the blog recommendations. I'm also looking for some good podcast recommendations for the walk to work? Do you have any favorites? Like Keith I'm a huge fan of Chemistry in its element (http://www.rsc.org/chemistryworld/podcasts/). I'm thinking of using these when I go back to teaching Inorganic Chemistry I in Spring 2014.

Favorite blogs?

As I was reading Kyle's post on the conversation on the Andre the Chemist blog, that go me thinking a bit about chemistry blogs and the fact that the academic year is finally over. Does anyone have good recommendations for "must read" (or even pretty good) blogs about chemistry and related subjects? I'd like to try and get in some good reading habits over the summer.
