  2. Abstract

    The National Research Council’s Framework for K-12 Science Education and the subsequent Next Generation Science Standards have provided a widespread common language for science education reform over the last decade. These efforts have naturally been targeted at the K-12 levels, but we have argued that the three dimensions outlined in these documents—scientific practices, disciplinary core ideas, and crosscutting concepts (together termed three-dimensional learning)—are also a productive route for reform in college-level science courses. However, how and why college-level faculty might be motivated to incorporate three-dimensional learning into their courses is not well understood. Here, we report a mixed-methods study of participants in an interdisciplinary professional development program designed to support faculty in developing assessments and instruction aligned with three-dimensional learning. One cohort of faculty (N = 8) was interviewed, and four cohorts of faculty (N = 33) were surveyed. Using expectancy-value theory as an organizational framework, we identified themes of perceived values and costs that participants discussed in implementing three-dimensional learning. Based on a cluster analysis of all survey participants’ motivational profiles, we propose that these themes apply to the broader population of participants in this program. We recommend specific interventions to improve faculty motivation for implementing three-dimensional learning: emphasizing the utility value of three-dimensional learning in effecting positive learning gains for students; drawing connections between the dimensions of three-dimensional learning and faculty’s disciplinary identities; highlighting scientific practices as a key leverage point for faculty ability beliefs; minimizing cognitive dissonance for faculty in understanding the similarities and differences between the three dimensions; focusing on assessment writing as a keystone professional development activity; and aligning local evaluation practices and promotion policies with the 3DL framework.

    Introductory courses are often designed to cover a range of topics with the intent to offer students exposure to the given discipline as preparation to further their study in the same or related disciplines. Unfortunately, students in these courses are often presented with an overwhelming amount of information that may not support their formation of a usable coherent network of knowledge. In this study we conducted a mixed-method sequential exploratory study with students co-enrolled in General Chemistry II and Introductory Biology I to better understand what students perceived to be the “take-home” messages of these courses (i.e., core ideas) and the connections between these courses. We found that students identified a range of ideas from both courses; further analysis of students’ explanations and reasoning revealed that, when students talked about their chemistry ideas, they were more likely to talk about them as having predictive and explanatory power in comparison with reasons provided for their biology big ideas. Furthermore, students identified a number of overlapping ideas between their chemistry and biology courses, such as interactions, reactions, and structures, which have the potential to be used as a starting place to support students building a more coherent network of knowledge.
