CHM 594: Modeling Instruction in Chemistry 2 - Syllabus
Instructors: Larry Dukerich firstname.lastname@example.org,
Erica Posthuma email@example.com
Class Meeting times (via Zoom): June 7-25, 2021. M-Th 8:30 am – 12:30 pm.
Office hrs Fri 8:30 – 10:30 am
Prerequisites: In-service teacher of chemistry or physics, or instructor approval. Participation in a multi-week Modeling Instruction in Chemistry I workshop, or instructor approval.
High school and community college chemistry teachers will participate in 48 contact hours of training in Chemistry: Modeling Instruction. The course will focus on an evidence-based approach to the internal structure of the atom, periodicity and covalent bonding, intermolecular forces, equilibrium and acids and bases. The name Modeling Instruction refers to making and using conceptual models of real systems and processes (both natural and artificial) as central to learning and doing science and engineering. Instruction is organized into modeling cycles rather than traditional content units. This promotes an integrated understanding of modeling processes and the acquisition of coordinated modeling skills.
The two main stages of this process are model development and model deployment. The modeling cycle addresses the deficiencies of traditional instruction by assisting students to construct understanding from observations, by confronting student preconceptions, by examining student thought processes through the process of “whiteboarding” and Socratic dialoguing. Participants will receive electronically stored versions of the course materials, as well as ancillary materials.
The goal of this Modeling Method course is to provide a meaningful form of professional development for teachers using student-centered, inquiry-based, constructivist practices. Participants will frequently be asked to play two roles. First, they will be asked to take the role of a novice student in chemistry (similar to their actual students) as they perform all the laboratory investigations and problem solving that such students will be asked to do. Armed with a taxonomy of common preconceptions and misconceptions students hold will give participants a useful perspective from which they will be better able to address their own student’s learning obstacles. Second, they will be asked to play the role of the classroom chemistry teacher where they will be able to practice the techniques of managing student discourse, using Socratic dialogue, and general classroom management in an inquiry-based classroom. Throughout the course, teachers are asked to reflect on their practice and how they might apply the techniques they have learned in the course to their own classes. The principles learned here can be readily transferred to any other sort of classroom instruction.
10 – Models of the atom
From an examination of the radiation emitted by hot metals and atomic gases, we conclude that atoms must have internal structure not explained by Thomson’s model.
11 – Periodicity and bonding
We extend the Bohr model to many-electron atoms, using it to provide a structural explanation for the organization of the Periodic Table, and to examine ionic and covalent bonding in compounds.
12 – Intermolecular Attractions and Biological Macromolecules
We use an electron density model to account for the attractions between molecules and their effect on physical properties. Then we move to an investigation of organic molecules important to life.
13 – Equilibrium
Various equilibria in processes (liquid-vapor, solute-solution, partition) and reactions are modeled by the exchange of particles between "containers". This exchange explicitly models rates of opposing processes.
Unit 14 – Acids and bases
Exchange of the acidic proton between species in acid-base equilibria and relative strengths of acids and bases is viewed in terms of competition by bases for H3O+ ions.
Because these concepts are ones with which teachers have less direct experience, as much emphasis will be placed on deep discussion of this chemistry content as on pedagogy.
There is additional enrichment on entropy (for AP and honors courses) on the probable direction of change. We adopt a "probability" view to account for the spontaneity of processes involving both structural and thermal change. This approach puts the “dynamics” back into thermodynamics!
Learning Goals: Through successful completion of this course, teachers will
● Improve their instructional pedagogy by incorporating the modeling cycle, inquiry methods, critical and creative thinking, cooperative learning, and effective use of classroom technology,
● Deepen their understanding of content in 2nd semester general chemistry,
● Experience and practice instructional strategies of model-centered discourse, Socratic questioning/whiteboarding, and coherent content organization,
● Strengthen local institutional support as school leaders in disseminating standards-based reform in science education,
● Increase their skill in all eight scientific practices recommended by the National Research Council in “A Framework for K-12 Science Education.”
The development and use of models are at the core of the NGSS Science and Engineering Practices.
Evaluation and Grading Procedures
Final grades will be based on the following point totals and percentages:
A: 90-100% (270-300 points total)
B: 80-89% (240-269 points total)
C: 70-79% (210-239 points total)
F: Less than 70% (less than 210 points total)
● Keep a reflection journal (120 points: 40% of course grade)
At the end of each unit, write a more detailed analysis of the unit, including strengths and weaknesses, how it is either resonant or dissonant with your own thinking about the content, how you might modify parts of the unit to fit your own style or teaching situation, etc. This ought to be 1-2 pages in Google Docs. Another option we’d like you to consider is to make at least one 10-15 min narrated screencast using Screencast-o-Matic*, Explain Everything** (or similar program) for your unit reflection in place of the written reflection. This could include some clips of any experiment or demo you performed. There are 5 units; we’ll award up to 20 points for unit 10 and 25 points for the remaining units (which are longer and more involved).
● Participate actively and thoughtfully in lab whiteboarding sessions, discussion of readings, activities, and problem-solving whiteboarding. (90 points: 30% of course grade). You are expected to attend all sessions of the course. If you must miss a session, plan to show up for office hours on either Friday.
● Submit a final paper (60 points: 20% of course grade) due on Tuesday, June 28.
The paper (at least 4 pages, double-spaced, 12 point font) should address how Modeling Instruction in 2nd semester chemistry differs from your current practice and what changes you plan to incorporate, or the issues with which you will have to deal in order to implement materials and strategies from the course in your classroom.
Š Submit plans for two activities modified or developed for pilot use in the classroom this school year. (30 points: 10% of course grade) Lesson plans must be in the same format as modeling teacher notes and lead to constructing a model or utilizing models to solve a problem. A lesson plan template will be provided.

Title IX is a federal law that provides that no person be excluded on the basis of sex from
participation in, be denied benefits of, or be subjected to discrimination under any education
program or activity. Both Title IX and university policy make clear that sexual violence and
harassment based on sex is prohibited. An individual who believes they have been subjected
to sexual violence or harassed on the basis of sex can seek support, including counseling and
academic support, from the university. If you or someone you know has been harassed on the
