NSF Grantees Poster Session
The laboratory environment can offer valuable first-person experiences that complement and extend the process of learning from other parts of a course. To this end, we are developing a unique laboratory curriculum for undergraduate general chemistry for engineers that more deeply engage students in authentic science and engineering practice. Our NSF-funded Improving Undergraduate STEM Education (IUSE) project involves curriculum reform for improving the experience of freshman engineering students taking general chemistry involves a series of Design Challenges, which are problem-based laboratory activities based upon the NAE Grand Challenges for Engineering. These Design Challenges situate chemistry concepts and skills in an authentic engineering context with supports for the engineering design process. For engineering majors, contextualizing the learning of chemistry in such a way is theorized to strengthen the connection between the domain knowledge of chemistry and its application in everyday work, which enhances interest, efficacy and learning. The user-centered design process enables us to keep our focus on the involvement of our target audience in all stages of development. In this paper, we present results from usability testing to illustrate our iterative evidence-based development process and offer results of an initial pilot study from across one semester of student use. For usability, data sources include video-recorded observations, field notes, student artifacts. For the pilot study, the assessed outcomes include chemistry content knowledge, self-efficacy, metacognition, and motivational variables. Both qualitative and quantitative analyses are used to address the research questions. Plans for additional re-design of the model and further study are discussed.
