Major curricula as structures for disciplinary acculturation that contribute to student minoritization

Institutions of higher learning are characterized by multiple, often intersecting, social-educational structures aimed at regulating the conditions by which a degree is ultimately granted. The sequence of courses that students must take for a degree is one such structure. Building on the Sloan Equity and Inclusion in STEM Introductory Courses (SEISMIC) Collaboration's prior work, we provide a comparative view of students' pathways through selected curricula at two participating institutions. We apply process analytics to students' course enrollments as a tool to reveal features of the curricula and the associated impacts on students' progressions to degree. Given the high enrollment in biology-related degree programs at these institutions, we focus on those and ask two questions: (1) Is the intended progression through the curriculum the one most commonly experienced by the students? and (2) does the maintenance of coherence and socialization into the discipline act in a similar way on individuals of different socio, economic and demographic backgrounds? Curriculum analytics tends to be driven by a reductionist view of its structure. Instead, we view the curriculum as a tool for disciplinary acculturation, revealing aspects of students' transitions through educational systems not captured by commonly applied course or retention analyses. Curricular structures and the constraints they impose impact the way individual students become members of a scholarly community by acting as a cultural and social homogenizing agent. Across the curricula and institutions in this study, we find that this process results in minoritization, hampering student progression through the curriculum and contributing to disciplinary exclusion in favor of traditionally advantaged socio-demographic groups. We call for curricular restructuring that (1) reduces or alters the depth of the hierarchical course sequences, changing the way progression is established; and (2) encourages adoption of pedagogical approaches in the courses that adapt to the learning community to which they cater; ultimately incorporating an asset-based approach to the acquisition of knowledge inclusive of students' diversity of backgrounds, experiences, and ways of being.
