This Exploratory Project is developing two prototype innovative instructional modules for grades 9-12 modules, and testing them extensively for useability and impact. These modules will emphasize the role of mathematics and computer science in planning for sustainability. The primary hypotheses is that short (roughly one week) interdisciplinary modules can positively impact students’ in the following ways: attitudes toward mathematics and computer science by immersion in sustainability topics of personal relevance; facility with cross-cutting skills in mathematical and computational methods; awareness of interdisciplinary issues in sustainability; empowerment to engage in sustainability discourse and exercise responsible citizenship; learning of the STEM practices and modes of inquiry necessary to become the next generation of interdisciplinary problem solvers; awareness of STEM educational opportunities and career paths related to sustainable living. The CSU STEM Center served as the evaluators for this project.
