Developing student learning goals and assessments for VIPEr learning objects

Submitted by Joanne Stewart / Hope College on Sat, 06/20/2009 - 07:47
Description

All VIPEr learning objects are supposed to include clear student learning goals and a suggested way to assess the learning. This "five slides about" provides a brief introduction to the "Understanding by Design" or "backward design" approach to curriculum development and will help you develop your VIPEr learning object.

First Look at Coordination Complexes

Submitted by Anthony L. Fernandez / Merrimack College on Sun, 09/06/2020 - 15:08
Description

When transitioning into inorganic chemistry from organic chemistry, students are surprised by the complexity of metal complexes. To ease this transition, students are asked to look at the crystal structure of a coordination complex [(+/-)cis-dichloro-bis(ethylenediamine)-cobalt(III) chloride monohydrate], make some observations about what they see, and provide a list of questions that they would like answered. Students usually note that there are atoms/ions that are "floating" and are seemingly unattached to anything else in the structure.

d-Orbital games

Submitted by Patricia Stan / Taylor University on Mon, 08/17/2020 - 12:55
Description

This is a great site for chemistry fun while you learn. They have multiple games, most free if you want to print your own.The card game that I am using is 18.  It is played like 21 or blackjack but uses metal centers and ligands to get to 18.  A fun way to teach 18 e- rule and familiarize students with ligands. My husband suggests using Dove squares instead of the optional benzene "chips" for "betting" which I think will make it very competitive.

Slap count also teaches counting 18 electrons.

Chemistry Icebreakers

Submitted by Anne Bentley / Lewis & Clark College on Sat, 08/15/2020 - 22:37
Description

We have developed a set of icebreaker activities that could be used at any course level, either in an online video chat or in a classroom. These are based on the popular Mad Libs game in which some words are left out of a story and players are asked to provide words to fill in the blanks without knowing much about the story. We've provided an introduction to the game, definition of typical parts of speech that are requested (ie, adverb, noun, adjective, etc), and three starter activities.

Jahn-Teller effect, theory and examples

Submitted by Adam Johnson / Harvey Mudd College on Thu, 08/06/2020 - 18:44
Description

At a recent SLiThEr workshop, a request was put out for an introduction to the Jahn-Teller effect. I had already prepared several slides showcasing single crystal X-ray data for my class this spring so I put this together with some additional examples from my lab and the literature.  Single crystal XRD data is presented to support the claims.

Easy and Inexpensive Conversion of Lab Safety Goggles to Face Shields

Submitted by Amanda Reig / Ursinus College on Thu, 08/06/2020 - 13:30
Description

In the time of COVID-19, a need for additional PPE in the form of face shields was deemed required for safe laboratory work when in the presence of other students and faculty.  An inexpensive method was devised to convert standard laboratory safety goggles into a face shield through the use of commercially available plastic report or presentation covers (sometimes called binding covers). This LO describes the fabrication process along with chemical compatibility and flammability testing of the purchased plastic sheets.

A cobalt hydroformylation catalyst tribute to Malcolm Green

Submitted by Chip Nataro / Lafayette College on Mon, 07/27/2020 - 20:00
Description

In this paper (Llewellyn, Green and Cowley, Dalton Trans. 2006, 4164-4168) the synthesis and characterization of two cobalt compounds with an N-heterocyclic carbene ligand (IMes) are reported. the first, [Co(CO)3(IMes)Me] was prepared by the reaction of [Co(CO)3(PPh3)Me] with IMes. The second compound, [Co(CO)3(IMes)COMe] is formed by the addition of Co to the first.

This is a short set of slides I use to introduce aspects of coordination chemistry for my foundation level inorganic chemistry class. 

Demonstration of Hard-Soft Acid-Base Theory: An Ion-Exchanger for Recovery of Rare Earth Metals

Submitted by Gary L. Guillet / Georgia Southern University Armstrong Campus on Wed, 07/08/2020 - 08:19
Description

The article from The Journal of the American Chemical Society by M. Kanatzidis et al describes a new ion-exchange material (FJSM-SnS) that shows high selectivity for rare-earth metals (REE) and very fast adsorption kinetics.  A number of techniques are used to characterize the properties of the compound that students may not be very familiar with but the article presents in an accessible way.

The reciprocal interview: A strategy for the first day of class

Submitted by Brad Wile / Ohio Northern University on Wed, 07/01/2020 - 12:54
Description

The reciprocal interview is a first day of class strategy described by Hermann and Foster,1 centered around changing classroom norms. The instructor begins by interviewing students about their goals and expectations for the course, before later turning these around as reasonable expectations of the students. In essence, this is a strategy to invite students to think about the course in a business-like environment, and view their expectations and the instructor expectations as originating from the same set of motivations.
