SLiThEr #52: Warming up for Inorganic- Helping students remember what we think they should already know

Submitted by Taylor Haynes / California Polytechnic, San Luis Obispo on Tue, 07/18/2023 - 15:15

Join us on Thursday July 27th at 4 PM EST for our 52nd Slither!

Sarah St. Angelo from Dickinson College will share some of her strategies for helping students remember concepts and skills from prior coursework that they "should" remember before her junior/senior inorganic course. Student-led review presentations, LMS-based warm-up topics and quiz, and a rapid collaborative recollection of models of bonding help Sarah's students remember important ideas and take ownership of their learning from early in the semester.

Description

This literature discussion on the Hot Paper communication in Chemistry, A European Journal; highlights the first examples of borepinium and borfluorenium cations whose optical properties can be tuned and also the very first reported example of thermochromism in these cationic species. R. J. Gilliard, Chem. Eur. J. 2019, 25, 12512. https://doi.org/10.1002/chem.201903348

A Strategy for Group Discussions of a Literature Paper: Roles That Rotate and Foster Different Skills

Submitted by Laurel Goj Habgood / Rollins College on Wed, 06/21/2023 - 12:12
Description

The "Lit Masters" concept is inspired by and adapted from one of my colleagues, Jenn Manak, in our education department. Students who are novices to reading the literature often are overwhelmed when assigned a paper to read and may struggle in group discussions. The strategy is to assign students to a semester-long group with designated roles for each paper that require them to produce a low-stakes artifact prior to class. During class time groups discuss the paper and it is followed with a debrief. 

Under pressure: Structure and bonding in actinide complexes (Arnold)

Submitted by Amy Price / UC Berkeley and Lawrence Berkeley National Laboratory on Fri, 05/26/2023 - 15:24
Description


This literature discussion focuses on a 2022 Nature Comm paper looking at the reasons behind the pyramidal structures of tri-coordinate f-element complexes. There is plenty to discuss in terms of bonding and coordination geometries in metal complexes, and the effects of pressure on coordination geometry.

Synthesis and Characterization of Aluminum Complexes of Redox-Active Pyridyl Nitroxide Ligands (Graves/Schelter)

Submitted by Shirley Lin / United States Naval Academy on Mon, 05/08/2023 - 08:32
Description

This literature discussion focuses on a Inorg. Chem. article that describes a series of Pt complexes that exhibit competitive reductive elimination reactions to form either an sp2-sp3 bond or an sp3-sp3 bond. One of the complexes also contains a C-C agostic interaction with the metal. The questions are written to be addressed by students in a foundation-level inorganic course.
