Goals of the ICLCS
* Strengthen rural high school teachers' and students' understanding of chemistry within the context of 21st-century research.
+ medicinal chemistry (biomedicine)+ materials science, including nanotechnology+ agricultural chemistry+ computational aspects of molecular-level chemistry
* Increase teachers' use of, and comfort with, computational and visualization tools.
* Create a cadre of teacher-leaders who will become advocates for excellence in science education.
* Promote institutional change in the university and school district partners.* Expansion to less-rural school districts
....thereby promoting sustainability

93 rural Illinois school districts
~100 high school chemistry teachers
~3,750 students
Basic High school curriculum (as relates to this talk)

We provide access to and training with modern computational and visualization tools
Use of free software when possible
ICLCS Fellows incorporate tools into their (existing) curricula to stimulate students' computational thinking.
Student can use the tools for inquiry-based learning about the world around them.
Design and Approach

1. Spreadsheets (Microsoft Office, or openoffice.org)
A table of values that are related through forumlas.
Examples of use:
a. Generate visual representations of data (data plots, bar graphs, etc.)
b. “Slider bars” allow the user to adjust interactively the value of a variable with a range.
Sample uses: Stoichiometry, Equilibrium, Reactions, Integrated rate laws, limiting reagents
