Background Methodology refers to the theoretical arguments that researchers use in order to justify their research methods and design. There is an extensive range of well established methodologies in the educational research literature of which a growing subset is beginning to be used in engineering education research. Purpose A more explicit engagement with methodologies, particularly those that are only emerging in engineering education research, is important so that engineering education researchers can broaden the set of research questions they are able to address. Scope/Method Seven methodologies are outlined and for each an exemplar paper is analyzed in order to demonstrate the methodology in operation and to highlight its particular contribution. The methodologies are: Case Study, Grounded Theory, Ethnography, Action Research, Phenomenography, Discourse Analysis, and Narrative Analysis. It is noted that many of the exemplar papers use some of these methodologies in combination. Conclusion The exemplar papers show that collectively these methodologies might allow the research community to be able to better address questions around key engineering education challenges, such as students' responses to innovative pedagogies, diversity issues in engineering, and the changing requirements for engineering graduates in the twenty‐first century.

Over the last several years, engineering faculty and learning scientists from four universities worked in collaboration to develop educational materials to improve the quality of faculty teaching and student learning. Guided by the How People Learn (HPL) framework, engineering faculty worked in collaboration with learning scientists to develop learner‐centered, student‐focused instructional methods. In consultation with learning scientists, engineering faculty carried out educational inquiry in their classrooms aimed at investigating student learning and enhancing instruction. In this paper we discuss the extent to which faculty engaged in these collaborative endeavors and how their teaching approaches differed as a result of their level of engagement. Study findings reveal the role that collaborative reflection plays in shaping teaching approaches. Results from this study provide insights for researchers and other practitioners in engineering and higher education interested in implementing engineering faculty development programs to optimize the impact on teaching.

The importance of ''size and scale'' in nanoscience and engineering has been recognized by both scientists and science educators. A solid understanding of this concept is key to the learning of nanoscience. Students, however, have been reported to have considerable difficulty grasping this concept; yet little is known regarding their state of understanding. To address this knowledge gap, we conducted a series of studies that were aimed at exploring the different ways students conceive of ''size and scale'' in the context of undergraduate nanoscience and engineering courses. Informed by Variation Theory of Learning (Marton and Booth, 1997), we identified four major categories (with two sub-categories within each) of student conception-fragmented, linear, proportional, and logarithmic. These conception categories, together with the aspects of variation that characterize and distinguish them, are summarized in a typology. In addition to serving as a diagnostic tool to describe students' understanding, this typology can also be used to guide the development of instructional interventions that facilitate students to move toward a more sophisticated understanding of ''size and scale.'' ß
