We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

In this paper, we present simple demonstrations aimed at explaining the fundamental principles of the photoacoustic effect. To display the audible phenomenon that occurs as laser radiation gets absorbed by ethene gas, an optical chopper was used to modulate the power of a continuous-wave laser whose beam was directed into a gas. The absorbed…

Student learning in simple electric circuits has been an important area in physics education research. This study builds off a previous investigation that applied the conceptual framework model to examine knowledge integration in student learning of simple electric circuits and developed a multiple-choice concept test for assessing knowledge…

The research aims to investigate the influence of integrating innovative teaching technologies on the effectiveness of the educational process and student motivation. This article employed a quantitative research design utilizing a questionnaire. The total number of participants in the study was 150 students. Participants were divided into…

General chemistry is a foundational course that most STEM students are required to take at some point in their academic careers, as such, thousands of students find themselves in a chemistry classroom every year. Students come into the classroom not only from different academic backgrounds but also from a variety of social and emotional…

First-generation students, especially in science, technology, engineering, and math (STEM) fields, have low persistence rates. Research shows that one of the barriers to their low persistence is a need for a student-centered pedagogical approach. Research has shown that if an instructor incorporates a pause technique during a standard lecture,…

Learning engagement and career-relevant skills are both important elements in learning. Unfortunately, there is a lack of research related to learning engagement in massive open online courses (MOOCs) from MOOC instructors' point of view. Research is also needed on MOOC instructors' strategies to provide career-relevant content to the learners. In…

Analogies are useful tools instructors can use to help make challenging concepts less abstract by drawing connections to familiar contexts. In this paper we provide an overview of the various analogies published in the education literature that are situated in the context of enzyme kinetics, including narrative-based analogies (analogies intended…

In this article, we present a revised version of the active learning classroom observation tool (ALCOT), designed in 2015, to support instructor reflection on instructional approaches applied within active learning classrooms. The design of active learning classrooms and teaching approaches within them have changed significantly since the initial…

Lectures are a commonly used teaching method in higher education, but there is significant debate about the relative merits of different classroom practices. Various classroom observation tools have been developed to try to give insight into these practices, beyond the simple dichotomy of "traditional lecturing versus active learning".…

To investigate the variation in active learning used in college science courses, the authors analyzed 57 comparison studies published in three prominent science education journals. Focusing on three sources of variation--(a) the active learning activities, (b) other pedagogical features, and (c) course structure/design--they found that most…

Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…

Flipped classroom in pharmacy education has been widely explored with a major focus on its effectiveness but little emphasis is given to assess the different in-class activities. Therefore, this work compares two in-class activities in an overall flipped classroom: analogical learning and team-based learning (TBL) for a pharmacy course. The…

My thesis work is focused on conceptual and epistemic learning and characterizing the environments in which this learning takes place. Earlier studies conducted by the Stowe group explored how instructional practices, instructional emphasis, and assessment emphasis relate to student outcomes in general and organic chemistry courses. Student…

Academic writing has been a widely substantial course in higher education as it plays a vital role in cultivating students' academic writing skills. Drawing on qualitative descriptive study, this study aims to explore the fundamental requirements for academic writing to base the creation of an effective learning framework. Data consisted of…
