Physics education has been identified as one of the public sectors that are mostly influenced by technological developments. This paper adopted the quasi-experimental pre- and post-test design to assess the effects of multimedia-aided technologies (MAT) on undergraduate students' performance in quantum physics (QP) at the University of Rwanda…

[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

In this study, firstly, university biology students' conceptual understanding and potential misconceptions concerning meiosis were studied. Secondly, an easily applicable drawing task was used to foster students' metaconceptual awareness which would help them to reach conceptual change. A quasi-experimental design with a non-equivalent control…

Chemistry laboratory experiences provide students the opportunity to engage all three domains of learning: psychomotor, cognitive and affective. However, they are often stressful environments where students are expected to quickly learn new laboratory techniques, and collect data in a short amount of time. In principle, providing additional…

General Chemistry is a course where students are expected to nurture the development of their fundamental concepts in chemistry. Students begin general chemistry with alternative conceptions about the topics and fragmented knowledge structures. Majority of students who successfully complete the general chemistry course sequence continue to hold…

In recent years, video-based lectures have been increasingly used in education as part of flipped classroom approaches, adult education, distance learning, and other applications. Though approaches in video-based lectures have been widely studied, less has been reported in the development of approaches to teach relevant technical skills, such as…

Team based learning (TBL) is a time tested teaching-learning (T-L) tool involving collaborative learning but has hardly been tested for teaching clinical biochemistry to undergraduate medical students. The present study was designed to (a) compare problem solving skills of first year MBBS students after attending a TBL session on 'organ function…

Despite recent interest in online learning, systematic comparisons of online learning environments with traditional classroom environments are limited, particularly in the sciences. Here, we report on a systematic comparison of an online and face-to-face classroom for a sophomore-level, lecture-only introductory inorganic chemistry course that is…

In a flipped classroom model, learning of basic content is shifted before class while in-class time is used for concept application. Empirical and controlled research studies are lacking on the best strategies to provide the necessary pre-class content instruction. In this study, we tested three methods of pre-class content learning--interactive…

This paper represents the second contribution from an action research study on a bachelor-level quantum chemistry and spectroscopy course. In the proposed instructional model, active learning principles are extended outside lectures to form a student-centred course structure. The new model resulted in superior learning outcomes compared to a class…

Several active-learning pedagogies involve groups of students working together to construct their own understanding of course content. In these classrooms, the instructor serves as a facilitator of learning, by interacting with every group, engaging students in discussions, answering questions, and providing formative feedback. This type of…

In very large lecture classes, student engagement is always a challenge, and many instructors use electronic student response systems (SRS) to promote student engagement and active learning. The conventional wisdom in using student response systems is that the technology matters less than the pedagogy; it is the added value of the instructor that…

This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

Light and spectroscopy are among the most important and frequently taught topics in introductory college-level general education astronomy courses (hereafter Astro 101). This is due to the fact that the vast majority of observational data studied by astronomers arrives at Earth in the form of light. While there are many processes by which matter…

With the goal of increasing the immediacy of the relationship between tenure-track professors and students, science departments in liberal arts colleges may try to arrange their curriculum so that students have the same professor in both the lecture and the lab section of introductory courses. While this goal seems laudable, empirical data are…
