Flipped Class Module - Lewis Structures of Industrially and Environmentally Relevant Molecules
Submitted by Jack F Eichler, University of California, RiversideEvaluation Methods:
1) Performance on the pre-lecture online quiz
2) Performance on the in-class activity (clicker scores or hand-graded worksheet)
Evaluation Results:
Students generally score on average 70% or higher on the pre-lecdure quiz, and on average 70% or more of students correctly answer the in-class clicker questions.
Description:
This is a flipped classroom activity intended for use in a first semester general chemistry course. Students are expected to have prior knowledge in identifyng the difference between molecular and ionic compounds, understanding the conceptual framework for how covalent bonds form, and how to draw Lewis dot symbols for atoms, and how to determine the number of valence electrons for atoms.
.
The activity includes:
1) pre-lecture learning videos that guide students through learning how to draw valid Lewis structures, determining how to caculate the formal charge for atoms in molecular compuonds/Lewis structures, and using formal charge to determine which Lewis structure is most stable if multiple Lewis structures are possible for a given molecule;
2) pre-lecture quiz questions; and
3) an in-class activity that requires students to apply their knowledge of chemical bonding in drawing Lewis structures.

Learning Goals:
Students should be able to:
a) draw Lewis structures of molecular compounds;
b) determine the formal charge of atoms in molecular compounds;
c) use formal charge to predict the most stable Lewis structure.

An improved method for drawing the bonding MO for dihydrogen
Submitted by Adam R. Johnson, Harvey Mudd CollegeEvaluation Methods:
When I do this correctly, the students don't accidentally see something which may make immature students giggle.
Evaluation Results:
I have had multiple colleagues tell me that this technique worked for them and saved them from repeating an embarassing classroom event.
Description:
Most of us have probably been there. Discussing homonuclear diatomic MO diagrams and on the first day you want to put up the sigma bonding molecular orbital for H2. If you teach it like me, you emphasize the LCAO-MO approach, so you draw a hydrogen atom with its 1s orbital interacting with a hydrogen atom with its 1s orbital...and then you notice giggling from the less mature audience members. My technique will help to prevent this from happening. The technique is in the "faculty only" files section.
Learning Goals:
The instructor will draw the bonding MO of dihydrogen without accidentally causing laughter in the class or self embarassment.
Corequisites:
Equipment needs:
chalkboard or whiteboard
ability to adjust quickly just in case

Topics Covered:
Implementation Notes:
I have come close to accidentally drawing the incorrect version of this diagram and I am able to stop myself quickly as illustrated in the instructions.
Time Required:
a minute to learn, a lifetime to master.

Chem 165 2018
Submitted by Adam R. Johnson, Harvey Mudd CollegeThis is a collection of LOs that I used to teach a junior-senior seminar course on organometallics during Fall 2018 at Harvey Mudd College. There were a total of 9 students in the course. The Junior student (there was only one this year) was taking 2nd semester organic concurrently and had not takein inorganic (as is typical).
