I conducted a set of four studies to catalogue and examine course elements, including active learning strategies and evidence-based teaching practices, and their influence on student experiences and performance in college biology classes. In the first study, I defined the term "active learning" and catalogued the 300[plus] strategies…

Organic Chemistry is considered by many to be the quintessential "weeder course", widely identified in the premed and STEM persistence literature as a gatekeeper to students interested in STEM or health fields (Barr, Gonzalez, & Wanat, 2008; Lovecchio & Dundes, 2002). There has therefore been considerable interest in determining…

Teaching students to construct scientific understanding is complex. Teachers who develop noticing skills can attend and respond to students' science ideas to move understanding forward. Traditional professional development (PD) approaches limit teachers' opportunities to develop noticing skills. This study examined what aspects of a collaborative…

The purpose of this study was to provide quantitative data about the effectiveness of the traditional lecture method of teaching in a college science course in contrast with an interactive case study method of teaching and learning. The study investigated one professor's teaching an Advanced Human Anatomy and Physiology course at Nebraska Wesleyan…

Introductory biology courses typically present topics on related biological systems across separate chapters and lectures. A complete foundational understanding requires that students understand how these biological systems are related. Unfortunately, spontaneous generation of these connections is rare for novice learners. These experiments focus…

High school biology classes traditionally follow a lecture format to disseminate content and new terminology. With the inclusive practices of No Child Left Behind, the Common Core State Standards, and end-of-course exam requirement for high school diplomas, classes include a large range of achievement levels and abilities. Teachers assume, often…

The primary purpose of this study was to investigate the effect of structured note-taking compared to traditional note-taking on the acquisition of scientific knowledge for students with and without learning disabilities (LD) and students with reading difficulties (RD). An additional purpose was to examine whether the two note-taking methods…

This qualitative case study investigated the teaching strategies that improve science learning of African American students. This research study further sought the extent the identified teaching strategies that are used to improve African American science learning reflect culturally responsive teaching. Best teaching strategies and culturally…
