Implementing an Environmental Contaminants Deliberation Module in General Chemistry.

Placing chemistry in the context of complex societal issues is one way to help students see the application of fundamental ideas in the general chemistry curriculum. Here, we describe the impact of an in-class deliberation on environmental contaminants, which encourages students to consider different perspectives when addressing the issue of water and soil quality in communities. Student surveys were used to analyze the quality of the deliberation and several key factors regarding student attitudes before and after the activity. Students report a high-quality experience during the deliberation, wherein new ideas were introduced and they carefully considered different views on the issue at hand. Not only do students gain scientific knowledge about lead contamination, they also demonstrate statistically significant gains in their attitudes toward chemistry and their motivation to take action. As a complement to traditional teaching methods, this deliberation module can address key learning outcomes in systems thinking and the impact chemistry has on society.
