The aldol condensation reaction is one of the many synthesis reactions carried out in second semester organic chemistry laboratories. This reaction was integrated into a novel experiment requiring students to synthesize dibenzalace tone derivatives using the crossed-aldol condensation by reacting different types of benzaldehyde derivatives with…

The use of Moodle quizzes as a continuous assessment and an integral part of the educational methodology in higher education has been analyzed in a case study of physical chemistry subject. Two types of quiz designed with different item types and different settings, called basic quiz (BQ) and thematic block quiz (TBQ), were elaborated making use…

The focus of this study was to find out the effectiveness of the jigsaw model on improving pre-service teachers' performance in selected functional group organic compounds. The study employed the quasi-experimental non-randomized pre-test/post-test intact class design. The sample was 144 pre-service teachers comprising 72 in the experimental class…

In undergraduate chemistry curricula that include computational modeling, students may gain first-hand experience in both introductory and advanced applications of this technique. However, although students can be exposed to the predictive power of computational work, its capabilities are often limited to determining the intrinsic properties of…

This paper reports the development and application of a low-cost multifunctional webcam spectrophotometer for the conduct of molecular absorption and fluorometric measurements. The equipment, which costs approximately US$20 to be fabricated, consists of a webcam, a diffraction grating, and a slit, all positioned inside an MDF box. Spectral…

This research draws on Legitimation Code Theory (LCT) to understand the epistemic dimension of the higher education classroom discourse of a professor who is well evaluated by his students. In expository science classroom discourse, concepts are loaded with different meanings, a process that is called "condensation of meanings" in LCT,…

Literature at the secondary level has demonstrated a tight interconnectedness between one's beliefs about teaching and learning and one's instructional practices. Moreover, this research indicates that personal and contextual factors influence beliefs and that growth and changes in beliefs are most notable during the early years of one's teaching…

This article presents and discusses the results of a study that investigates university students' comprehension of the concept of molar concentration, following teaching and evaluation of the subject. The specific problems underlying learning of this concept have not yet been focused on in sufficient detail or depth. A "Reasoning with…

Students often struggle to make interdisciplinary connections and cite a lack of opportunity to make such connections. To address this issue, we are developing activities aligned with the framework of three-dimensional learning that provide students with opportunities to make connections between chemistry concepts and biological phenomena. Here,…

As an outcome of multidiscipline integration, the polymeric surfactant is of growing importance in modern industry and scientific research. However, the instructional introduction on polymeric surfactants is still insufficient in universities nowadays. In order to effectively guide undergraduates to study polymeric surfactant, a new polymeric…

There has been a recent rapid increase in the number of primary studies comparing the impacts of flipped to traditional instruction in undergraduate chemistry courses. Across these studies, there are wide variations in flipped model design, implementation, and reported impacts. To investigate these variations, 28 primary peer-reviewed studies were…

In response to the realization that qualified applicants' choice of a career in chemistry is declining, we investigated the factors involved in chemistry and chemical education career choice. Building on the social cognitive theory (SCT) and the social cognitive career theory (SCCT), this research examines the personal, environmental, and…

Oxygen reduction reaction (ORR),as a multielectron electrode reaction, is an important electrochemical reaction in the field of electrochemical energy storage systems. Herein, a new advanced electrochemical laboratory experiment is designed for undergraduates to master the preparation of oxygen reduction catalytic electrode. Students can use…

Successful mastery of multistep synthesis is an essential learning objective in the completion of the organic chemistry sequence. This entrepreneurial class project was designed to incentivize students to master multistep synthesis through role-playing as an entrepreneur. In short, students play the role of a group member in a startup whereby they…

The American Chemical Society (ACS) supports community college chemistry faculty by addressing curriculum, laboratory, and safety issues; however, these faculty are underrepresented in the ACS governance structure, which contributes to under-serving two-year college specific needs and low engagement by two-year faculty in the ACS.
