In 2017, the Department of Biology at Virginia Wesleyan University modified its two-course introductory sequence in response to high DFW rates (>50% scoring a D, F, or withdrawing) in the first semester. The revised curriculum created a new third course and moved content that many students struggled with from the first semester to the third…

In this paper I explain how I usually introduce the Schrödinger equation during the quantum mechanics course. My preferred method is the chronological one. Since the Schrödinger equation belongs to a special case of wave equations I start the course with introducing the wave equation. The Schrödinger equation is derived with the help of the two…

In course design, topic outline organization encompasses the structuring and sequencing of topics to be delivered in a learning environment. Recent studies in topic outline optimization revolve around massive open online courses (MOOCs) due to their abundance but not much has been studied on the traditional courses. This study investigates the…

Educators are constantly looking to improve their pedagogical strategies. This can range from teaching strategies for a specific topic to holistic curriculum changes. Recently, the approach that chemistry departments have chosen to deliver their introductory courses has garnished increasing attention from educators. Our department recently…

This study examines students' visual behaviors when they tackle two types of synthesis problems, sequential and simultaneous problems. Sequential synthesis tasks can be solved by applying pertinent concepts consecutively, whereas simultaneous synthesis tasks require concurrent application of multiple concepts. Twenty-two students from an…

Spatial skills, which represent the ability to mentally manipulate objects (Schneider & McGrew, 2012; Atit et al., 2020) have been shown to be correlated with entrance, persistence and success in STEM (Shea et al., 2001; Wai et al., 2009). Specifically, these skills have been shown to be necessary to geologists and geoscientists (Hegarty,…

Identifying contingencies between constructs in a multi-faceted learning progression (LP) is a challenging task. Often, there is not enough evidence in the literature to support connections, and once identified, they are difficult to empirically test. Here, we use causal model search to evaluate how connections between ideas in a genetics LP…

Integrated computing curricula combine learning objectives in computing with those in another discipline, like literacy, math, or science, to give all students experience with computing, typically before they must decide whether to take standalone CS courses. One goal of integrated computing curricula is to provide an accessible path to an…

Whether to engage student preconceptions to facilitate conceptual change is an area of debate among conceptual change theorists. Here, we evaluate the efficacy of a preconceptions-based instructional sequence about groundwater previously described by (Arthurs, 2019). To assess the impact this instructional sequence had on facilitating the…

This quasi-experimental, pre-post study with non-equivalent comparison groups explores the potential for resequencing of course content to affect positive change in an undergraduate, introductory statistics course at a mid-sized, flagship university that is located in a southern state. Quantitative analyses suggest that the implementation of…

Formative assessment has long been used to gauge students' understanding of course material prior to taking an exam. With the advent of more advanced technology, only recently have instructors been able to combine formative assessment with a student response system to allow students to respond to questions in real time during class. Previous…

The cyclic format of the undergraduate physics curriculum depends on students' ability to recall and utilize material covered in prior courses in order to reliably build on that knowledge in later courses. However, there is evidence to suggest that people often do not retain all, or even most, of what they learned previously. How much information…

Studies have shown that students' positive experience during their first year in college plays a significant role in their success in terms of persistence and satisfaction. That premise has been the motivation for the development of a first-year connection course by the Department of Chemical Engineering at Tennessee Tech University. Recent…

Low passing rates in developmental mathematics have been a serious concern for community colleges for many years. A course in Quantitative Literacy (QL) offers non-STEM students an alternative option to introductory algebra as a path to a degree. This paper describes the implementation and evolution of QL at the Borough of Manhattan Community…

Adaptive curriculum sequencing (ACS) is still a challenge in the adaptive learning field. ACS is a NP-hard problem especially considering the several constraints of the student and the learning material when selecting a sequence from repositories where several sequences could be chosen. Therefore, this has stimulated several researchers to use…
