Symmetry Questions

Submitted by Joseph Keane / Muhlenberg College on Fri, 01/08/2016 - 15:12

The D5h character table lists 2 S53 operations.  My background in group theory is (obviously) not the strongest.  I would have told my students to list 2 S52 operations, as consistent with the listed 2 C52 operations.  Is there a short explanation of why S53 is the prefered notation for the improper rotations?  When I first introduce this notation, I tell them that we try to minimize the value of the superscripts, thus, for instance, C3 rather than C62 in D

LFSE

Submitted by Marites (Tess) Guinoo / University of St. Thomas on Mon, 12/07/2015 - 12:45

I noticed that different books have a different sign convention for LFSE.  The new editions of Miessler, Shriver and Housecroft uses the negative energy convention (- delta o + paring energy), while the older edition of Shriver and Huheey uses the positive energy convention (+ delta o - pairing energy).  

I'm curious, how do you teach LFSE? the negative or positive convention?

Which one is a better approach to the LFSE?  Do you know of a literature reference for this?

very small class

Submitted by Adam Johnson / Harvey Mudd College on Thu, 10/15/2015 - 15:26

So, it appears that I will have 5 or possibly 6 students in my inorganic class. The smallest I've ever had this class is more like 10-12. Any thoughts or tips on teaching a class this small? I don't feel like lecturing will work (my organometallics class is regularly <10 and I don't lecture much there, instead I do this). 

This fall I am teaching gen chem with an emphasis on case studies and small group problem solving. I'm guessing I will try something like that...

Great Expectations: The Undergraduate Inorganic Curriculum

Submitted by Barbara Reisner / James Madison University on Sun, 08/30/2015 - 12:58

The results of the Survey on the Undergraduate Inorganic Curriculum are now (well, probably 24 hours from now) available in Inorganic Chemistry (http://dx.doi.org/10.1021/acs.inorgchem.5b01320). 

In the paper we've presented the results of the survey, our interpretation, and our preliminary recommendations. However, we believe that these results merit a community discussion and hope that you'll share your perspective on the undergraduate inorganic curriculum in this space on VIPEr.

Electronic resources for Gen Chem: Sapling homework and Openstax textbook

Submitted by David Laviska / Seton Hall University on Mon, 08/24/2015 - 14:31

Does anyone have thoughts to share (good or bad) on either or both of these resources? I will be teaching Gen Chem I and II at Rider University this year and we are adopting these teaching tools. The textbook is available free and therefore represents a significant cost savings for the students (https://openstaxcollege.org/textbooks/chemistry). I have looked through the book and it seems to be pretty solid, but haven't used it for teaching yet.

"Other" Resources Used for Teaching Inorganic Chemistry - Results from the 2013 Survey

Submitted by Barbara Reisner / James Madison University on Wed, 06/10/2015 - 14:27

The 2013 Inorganic Curriculum Survey asked respondents about the resources they used when they teach inorganic chemistry. The choices included inorganic chemistry textbooks, activities from the Journal of Chemical Education, articles from the primary literature (e.g., JACS, Inorg. Chem.), demonstrations, online homework, online resources, podcasts, videos, Wikipedia, and other. About 20% of respondents selected "other" and provided information about these resources.

Anyone with experience (good or bad) with Smartwork homework system?

Submitted by Hilary Eppley / DePauw University on Thu, 05/28/2015 - 16:29

In our introductory class, we've periodically used Sapling online homework system.  We are looking at a new book for the fall that comes with the Smartwork homework system which seems quite a bit like Sapling.  Anyone have any experience with both and can talk about the differences and pros/cons other than price?

Grading Multiple Choice Exams

Submitted by Amanda Reig / Ursinus College on Sat, 04/25/2015 - 23:30

We are a small school with relatively small classes.  My exams (for any course/level) typically contain at most 10 multiple choice questions.  However, we are now administering the ACS exams as final exams for many of our courses.  Since I started, we have always graded these by hand using self-generated answer sheets where students write in their choice (no bubble filling).  For multiple reasons, we think we need a more efficient (and accurate) system.

Integrating Literature Discussions into the Syllabus

Submitted by Anne Bentley / Lewis & Clark College on Mon, 04/20/2015 - 13:41

I describe the various ways that I've incorporated literature discussion learning objects (LOs) into my inorganic course in a BITeS blog post. I'm curious to hear more about what others have done.  Do you sprinkle discussions throughout the course?  (At the end of each section? How many?) Do you save them all for the end? Do your students work on articles individually or do you prefer to have the whole class read articles together?

Of course there isn't a one-size-fits-all solution....
