The construction and characterization of a glucose biosensor has been implemented in an instrumental chemical analysis course to provide students experience with chemical sensing, electroanalytical methods, and flow injection analysis (FIA). The glucose biosensor was assembled on a glassy carbon electrode by depositing a layer of Prussian blue…

Sustainability issues are a problem in Chile because of the policies of the present and previous governments. Chile has a neo-liberal model for development and many ecological problems, which involve social and environmental injustices and an overvalue of economic growth for development. Building on the three pillars model of sustainability of…

As detection and subsequent remediation of misconceptions developed within high-school organic chemistry courses in regard to various classes of organic compounds are a prerequisite for meaningful learning of more advanced organic chemistry content, this study sought to identify high-school students' misconceptions about alcohols and carbonyl…

Three visions of scientific literacy have been discussed in the literature of science and chemistry education, but little is known of their embodiment in chemistry curricula. Grounded on the conjunction of the three visions of scientific literacy and the subject matter of chemistry, this study investigated the manifestation of scientific literacy…

General chemistry is a gateway course that students from several STEM-related majors take at the beginning of their college careers. Faced with high attrition rates of students in STEM fields and even higher rates for groups minoritized due to gender and ethnicity/race, this study explored how a general chemistry course influenced students'…

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…

Recently, scholars have suggested a co-design collaboration with instructors and students to effectively implement formative assessment (FA) practices because it ensures a high-quality design that considers users' needs, values, and goals in a specific learning context. This study examines the effect of co-designed FA practices, in which…

Content coverage is frequently identified by faculty as a barrier to the implementation of student-centered instructional strategies. This need to cover content may be a personal belief faculty hold and/or an external requirement imposed (or perceived to be) on them ("e.g.," by their department, institution, accreditors,…

Approaching elective courses and courses on special topics in Chemistry can seem daunting at times, given the varied backgrounds of the students, together with the broad nature of topics. Often, institutions may give incentives for creating sustainability related course offerings, but knowing where to start and how to organize the information…

As implementation of green chemistry into university-level courses increases, it is vital that educators have a tool to rapidly measure student knowledge of green chemistry principles. We report the development of the Assessment of Student Knowledge of Green Chemistry Principles (ASK-GCP) and evaluation of its sensitivity and effectiveness for…

Introductory chemistry textbooks often present valence bond (VB) theory as useful, but incorrect and inferior to molecular orbital (MO) theory, citing the electronic structure of O[subscript 2] and electron delocalization as evidence. Even texts that initially present the two theories on equal footing use language that biases students toward the…

The results of an earlier four-year longitudinal research study on the development of experimental design skills led to the conclusion that 12-13 year old students probably need more help to design experiments than had been offered to them in that project. This paper reports the findings of the first year of a further four-year empirical research…

In their second year at the university, preservice chemistry teachers are confronted with organic chemistry. Because it is known that students often struggle with the subject, a new course design was developed, used, and evaluated for this study. To ensure meaningful learning, the students had many opportunities to actively participate in the…

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…

The aim of this paper was to investigate chemistry teachers' attitudes towards certain characteristics of the nature of science and history and philosophy of science, and the influence of those views on their teaching practice. The sample comprised 272 chemistry teachers. A questionnaire was used for data collection. Most teachers recognised some…
