In chemical engineering, laboratory experiments play a critical role in shaping students’ understanding of the profession, offering students opportunities to make decisions – to use their agency. However, such experiments vary greatly in their relevance to the work of chemical engineers and in the consequentiality of the decisions students can make. We investigate the role that having consequential agency has on students’ perceptions and development. Students completed surveys as part of their post-lab assignments that measured persistence intentions, engineering identity, demographics, relevance, agency in four domains: (1) experimental design; (2) experimental oversight and data collection; (3) data analysis and interpretation; and (4) communication of results. Using regression modeling, we found that engineering identity strongly and positively predicted persistence intentions. Relevance and consequential agency over experimental design (Domain 1) and communicating (Domain 4) predicted engineering identity. We will report the implications in a regular session.
