nanoCHAts: Informal conversations about teaching

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

Anion Coordination Chemistry (Bowman-James)
Description

Ligands can bind to anions, just as they do to metal ions, and Bowman-James developed these analogies as well as many examples of selective anion binding ligands.  This short slide decks gives background to her work as well as some relevant introductory material.

reaction of PPh3 with elements--the COVID edition
Description

This is a research-like laboratory experience based on the one posted by Brad Wile (linked below). My students are mostly juniors and have had 2 semesters of organic. This spring they are taking the inorganic laboratory virtually, so I wanted to give them a more exploratory lab experience. Their job will be to watch the YouTube videos to see the synthesis and isolated products, and then propose characterization methods they want to employ to identify both the identity and purity of the compounds.

Development of Expanded Porphyrins (Sessler)
Description

The LO focuses upon classic articles describing the synthesis and characterization of the first "texaphyrin" compounds.

This LO is part of a special VIPEr collection honoring the 2021 ACS National Award recipients in the field of inorganic chemistry. Jonathan L. Sessler was the recipient of the Ronald Breslow Award for Achievement in Biomimetic Chemistry for the discovery of expanded porphyrins, molecular recognition via base-pairing, pyrrole-based anion binding, and demonstrating the power of this biomimetic chemistry in drug discovery.

The Organometallic Chemistry Behind the Polymer of Squares (Chirik)
Description

The discussion covers a 2021 publication by the Chirik group (Nature Chemistry, 2021, DOI: 10.1038/s41557-020-00614-w) which details the discovery of a new way to polymerize butadiene through iron-catalyzed [2+2] cycloadd

Resolution of Werner complexes -- the COVID edition
Description

This is a classic experiment that has been revised and updated numerous times over the years. The experiment can be found in Girolami, Rauchfuss and Angelici, 3rd edition, but that edition removed some purification steps that were present in the earlier edition which has plagued generations of my students with poor resolution of the enantiomers. Marion Cass published a J. Chem. Educ. article in 2015 that included a pH determination and added back in the recrystallization step. This allowed my students to achieve higher yields and greater resolution in Spring 2020.

Linkage Photoisomerization of SO2 Bound to Osmium
Description

In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.

SLiThEr #7: Assessment Using Literature Discussions

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 17:55
Description

This is the seventh SLiThEr () in the series. In this presentation/discussion, Dr. Shirley Lin explains how she used a literature discussion with students to assess their learning and knowledge. This was for a upper-division senior seminar course. In particular, she discusses questions at various levels of Bloom's Taxonomy. She also explains how to use concepts from Chemical Education Research to really dig down and assess student knowledge. 

SLiThEr #4: Flipping Undergraduate Inorganic Chemistry: Effect on Diversity and Inclusivity

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 15:09
Description

This is the 4th in the series of SLiThErs (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable). This was presented by Dr. Caroline Saouma on how flipping her inorganic chemistry course helped diversity and inclusivity. This ties in very well with SLiThEr #3, which was on flipped classrooms as well (https://www.ionicviper.org/web-resources-and-apps/slither-3-flipping-yo…). 

SLiThEr #1: Creating online inorganic chemistry labs

Submitted by Kyle Grice / DePaul University on Tue, 12/29/2020 - 14:29
Description

This is the link to the first SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable), presented by Kyle Grice and Hosted by Chip Nataro. The SLiThEr was recorded and posted on YouTube (see the web resources link). 

This particular roundtable focused on the teaching of a Junior/Senior-level inorganic chemistry laboratory completely online. Kyle presented on what he did in Spring 2020 when he had to pivot quickly to a fully remote modality with only a week or so of planning.
