Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…

The COVID-19 pandemic presented many challenges for educators. In Course-based Undergraduate Research Experiences (CUREs), where students learn about the scientific process by working on novel research, few resources for remote learning were available. Here the impact of changes to course delivery format on student learning gains in a…

The COVID-19 pandemic led to an abrupt suspension of face-to-face teaching activities in higher education institutions across the globe. The instructors and faculty at most institutions have had to adapt, invent, and implement adjustments quickly to adopt an online learning environment. This has been an extraordinarily challenging time for both…

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…

This study examines the interest, motivation, and behavioral engagement of college students in an introductory course relative to three instructional formats used in the course: hands-on, problem-based laboratory stations; problem-based written case studies; and video lectures. Groups of five to seven students were assigned learning activities as…

This study examines the effectiveness of pre-laboratory presentations in an undergraduate general chemistry laboratory using two different modes of delivery: a traditional lecture versus an in-class video presentation. It was anticipated that implementation of videos could result in improved laboratory efficiency, safety, and necessary technical…

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…

The advent of new educational technologies has stimulated interest in using online videos to deliver content in university courses. We examined student engagement with 78 online videos that we created and were incorporated into a one-semester flipped introductory mechanics course at the Georgia Institute of Technology. We found that students were…

In this article we summarise over 60 reports and research articles on pre-laboratory activities in higher education chemistry. In the first section of the review, we categorise these activities as follows. First are those intending to introduce chemical concepts, that typically take the form of a pre-laboratory lecture, pre-laboratory quizzes, and…

The current model of flipped classroom ensures that learning is not being restricted to the brick and mortar setting. Lessons can be conducted anywhere, anytime, as long as there is a good internet connection. Most of the flipped classroom and e-lectures are videos recording PowerPoint slides with a human voice as the audio instruction. In…

Interactivity and inquiry-based learning science are effective ways of helping students overcome their perception of chemistry as an alien and abstract topic and instead approach the subject as a creative way of understanding ideas and applying mastered concepts to new contexts. Data acquisition systems are an extremely useful form of educational…

Attempts to bring authentic science into the K-16 classroom have led to the use of sociocultural theories of learning, particularly apprenticeship, to frame science education research. Science educators have brought apprenticeship to science classrooms and have brought students to research laboratories in order to gauge its benefits. The…

One critical element of increasing science literacy is student engagement. In this article, I report on the impacts of changing an introductory environmental science class to move away from standard lecture delivery and increase student engagement in science. The class was designed around small-group activities, inquiry labs, and substantial use…

Teachers know what a daunting job it can be to ensure that all students in a class learn effectively. In addition to the usual difficulties of gaining everyone's attention at once, instructors also run into the issue of preferred learning styles. In any classroom environment, the same topic is taught to multiple students, and each student may…
