A new perspective on chemistry learning could be the optimal learning moment of view based on flow theory. Optimal learning moments (OLMs) that occur when students experience high levels of interest, challenge, and skill at the same time were investigated in this study. Participants of the study were 47 pre-service science teachers. Data were…

Most chemistry students struggle with interpreting and understanding NMR (nuclear magnetic resonance) spectra and the general concepts of NMR spectroscopy. NMR spectroscopy seems to be difficult to both teach and learn. Therefore, the corresponding courses should be investigated in more detail. We conducted a survey with N = 39 German university…

Retention of students' attention in general chemistry courses stands as one of the main challenges that educators are facing in classes of any size and is especially prevalent with classes composed of mixed majors. Herein, we describe our experience with introducing short, 10 min student lectures ("flash talks") on popular chemistry…

This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

The low Cumulative Grade Point Average of most chemistry undergraduates results in their low achievement and motivation which poses a threat to the production of future chemistry teachers. The diversity of this problem has resulted in several suggestions concerning the application of Google Meet strategy to determine its efficacy in ameliorating…

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…

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…

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…

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…

This study investigates the instructional practices of a chemistry professor during an immersion summer program, with a focus on employing multimodal discourse within a studio-based learning environment. For this study, multimodal discourse includes natural language, gestures, mathematical expressions, symbolic visual representations, and manual…

Despite the substantial progress made to develop evidence-based pedagogical practices that support student learning, many courses are dominated by "traditional" practices such as a passive lecture. Thus, a continued focus on reforming courses is necessary. Here we describe the deliberate practice-driven reform of a large lecture-format…

This article outlines an exploratory study that investigated students' perceptions of the benefits and disadvantages of lecture recordings delivered as part of an introductory chemistry program in the UK during the COVID-19 lockdown in Spring 2020. Three features of these lecture recordings are considered: 1) the production of a series of…

Students come into the classroom with a variety of background knowledge. Therefore, it is imperative that educators are able to help all students, regardless of their familiarity with the content. Since it can be challenging for some large enrollment classes to schedule recitation classes after lectures due to logistical constraints, this study…

Active learning pedagogical approaches and methodologies have been shown to increase undergraduate student success. Specifically, the flipped classroom approach pushes course content outside of the classroom, allowing for the focus of each class period to be centered on student-student interactions and reducing student cognitive load in comparison…
