Teaching organic chemistry requires supporting learning strategies that meaningfully engage students with the challenging concepts and advanced problem-solving skills needed to be successful. Such meaningful learning experiences should encourage students to actively choose to incorporate new concepts into their existing knowledge frameworks by…

General chemistry courses are key gateways for many Science, Technology, Engineering, and Mathematics (STEM) majors. Here, we report on the implementation and evaluation of an adaptive, ALEKS-based online preparatory module (PM) for general chemistry. The module was made available in Summer 2018 at no cost to all students entering any section of…

This paper reports on the relationship between the pre-service teachers' enacted Topic Specific Pedagogical Content Knowledge (eTSPCK) observable in the classroom teaching of Organic Chemistry and learner achievement in the topic. The study employed a mixed-methods research design with a sample of 17 pre-service teachers (PSTs). The PSTs were…

This paper uses evidence-centered assessment design (ECD) to structure and analyze a laboratory activity where students collect and represent titration curve data to determine acid strength in terms of molarity and dissociation constant. Following principles of multidimensional learning, the activity prompts students to demonstrate knowledge of…

Students' negative perceptions of physical chemistry courses are well-known and are likely impacting their learning and performance in this upper-division course for majors. The syllabus can be the first interaction students have with a course and instructor and can be central to the expectations student set for the learning experience. While…

Activities that engage high school students in visualizing chemical phenomena can help them develop representational competence to think about and communicate their understanding of these phenomena. This paper presents a collaborative learning activity that can engage precollege students in designing a poster that describes four different types of…

Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Two scales measuring teaching self-efficacy and beliefs were developed from previous instruments for use with near-peer facilitators assisting with peer-supported pedagogies. Construct and face validity, measurement reliability, and factor structure were determined using a population of nearpeer facilitators working in a peer-led team learning…

Peer learning programs have been developed to support many introductory science courses by providing additional instruction and engagement. These programs are beneficial to both learners and instructors, providing content learning and confidence and attitudinal gains. There is evidence that the benefits of peer learning are higher when students…

Rarely are scientific phenomena isolated to a single discipline such as biology, chemistry, physics, Earth science, or others. Rather, these phenomena span multiple disciplines and often require bringing together content and understandings from multiple disciplines to engage with or explain the target phenomena. This study uses a model-based…

This study investigated the introduction of the second law of thermodynamics using the Legitimation Code Theory (LCT) (semantic waves) among first year chemistry students. The aim of the study was to investigate the extent LTC (semantic waves) reduce the entropy concept's complexity and abstractness when introducing the second law of…

Organosliding is a game adapted from sliding puzzles to teach structural formulas of alkanes to undergraduate students. The goal of this game is to arrange the pieces of the sliding puzzle to form a Kekulé formula of any alkane. The objective is to create as many formulas as students can from one puzzle. The effectiveness of the game was evaluated…

Two-stage quizzes and exams were implemented for both in-class quizzes and term tests in three sections of first-year General (Introductory) Chemistry. In the first stage, students completed the exam individually and submitted their papers. In the second stage, students collaborated with peers to complete a subset of the exam questions. The aim of…

Research has called for greater emphasis on outdoor science activities in preservice teacher education. Therefore, in this study, preservice teachers reflect on an outdoor chemistry unit that aimed to model outdoor science activities to be conducted in local settings within short time frames. Data from the preservice teachers' reflections were…

This undergraduate dissertation project was designed to enhance organic and analytical chemistry skills of final year forensic science students. A modified Birch reaction method was employed to synthesize amphetamine from ephedrine and detect the most known byproduct of clandestine manufacture of amphetamines, e.g.,…
