Learning Assistants (LAs) are undergraduate students who have previously succeeded in a course and return to assist faculty in engaging current students. The authors used a mixed methods approach to explore changes in LAs' teaching self-efficacy and pedagogical knowledge (PK) over a semester. They found that LAs significantly improved their…

Small group interactions and interactions with near-peer instructors such as learning assistants serve as fertile opportunities for student learning in undergraduate active learning classrooms. To understand what students take away from these interactions, we need to understand how and what they learn during the moment of their interaction. This…

Students often experience science, technology, engineering, and mathematics (STEM) courses as competitive, weed-out spaces. Learning Assistants (LAs) have potential to improve students' experiences in these courses. Previously, we elucidated themes describing the impact of LAs on students' sense of STEM belonging and science-related confidence in…

The University of Wyoming recently implemented a Learning Assistant (LA) program with the goal of supporting undergraduate students in traditionally lecture-based STEM courses. The authors performed a multi-method qualitative study utilizing a focus group and individual interviews in order to investigate the impact of the program's pilot year on…

A growing number of university STEM departments are incorporating active learning practices in their courses in response to evidence of the general effectiveness of such practices. Professional development for instructors new to active learning practices is increasingly important as efforts extend to reach past early adopters to engage a wider…

Active learning has often been reported to improve student outcomes in STEM courses. However, there are barriers to its implementation, and it is challenging to include this approach in large classrooms with fixed seating. This investigation explores the development of a novel approach in which the class contact time was reallocated for a general…

Contribution: This study identifies the types of interaction that contribute to student learning with student-led tutorials (SLTs). The quality of these interactions include peer discussion, student tutor presentation, joint reasoning, and constructive feedback. Background: The introduction of SLTs in an advanced electromagnetics bachelor course…

There is an assumption that graduate teaching assistants (GTAs) have mastery of the chemistry content they are teaching and preparation to instruct students. However, in reformed classrooms, GTAs may need more support and resources. We designed chemistry rehearsal modules for use in a mixed-reality teaching simulator to help prepare GTAs for…

In order to improve the student success rate in a "gateway" undergraduate Biology course, changes were made to both content delivery and classroom support, and the impact of these changes was measured. Requiring students to interact with course material prior to class time by viewing pre-recorded lectures freed up time in class to delve…

Recent reform efforts in postsecondary science teaching have called for shifts in instructional methods to include more evidence-based instructional practices. However, a myriad of factors play a role in whether an instructor adopts these more student-centered methods. One such factor is teaching perspective. In this study, we explored the…

This quantitative, exploratory study examined whether a Project-Based Guided Inquiry (PBGI) chemistry laboratory course supported more incremental ability beliefs among students, examined achievement outcomes for students grouped based on changes in student-reported chemistry ability beliefs from pre- to post-course, and provided explanations for…

We redesigned our undergraduate laboratories to create a structured sequence that continuously improves the learning experience of students. We utilized a PBL and PjBL approach in which students are progressively introduced to ill-structured open-ended problems, the development of projects, and the creation of research products. We dynamically…

Large introductory science courses are a particularly important and challenging target for creating inclusive learning environments. In this study, we examined the impact of incorporating learning assistants (LAs) on the learning environment in an introductory biology course taught with two different structures: an in-person lecture with…

Background: Active learning supports student performance, but can be challenging to implement in large courses. The Learning Assistant (LA) Program is a growing intervention to support students in large active learning classrooms. This program places advanced undergraduates who have training in pedagogical methods in active learning classrooms to…

Active learning classrooms (ALCs) support teaching approaches that foster greater interaction and student engagement. However, a common challenge for instructors who teach in ALCs is to provide adequate assistance to students while implementing collaborative activities. This study examined the impact of teaching assistants in a large ALC. The…
