Aldol chemistry is highlighted in many introductory organic chemistry laboratory experiments because it provides synthesis, mechanism, and experimental challenges for students. In the experiment described here, students synthesize dibenzalacetone derivatives by crossed aldol condensation, observe reaction rates using a semiquantitative rubric, and…

Research on student argumentation in chemistry laboratories has mainly focused on evaluating the quality of students' arguments and analyzing the structure of such arguments ("i.e." claims, evidence, and rationale). Despite advances in these areas, little is known about the impact of activity framing on the nature of student…

Acid-base chemistry is a key reaction motif taught in postsecondary organic chemistry courses. More specifically, concepts from the Lewis acid-base model are broadly applicable to understanding mechanistic ideas such as electron density, nucleophilicity, and electrophilicity; thus, the Lewis model is fundamental to explaining an array of reaction…

Is the reductionist approach to teaching chemical principles in the laboratory adequate for students to make effective evaluations? In this work, using the example of sunscreens, students first assessed the analytical chemistry parameters of the active ingredients, later comparing and contrasting them with organic chemistry information for…

Educators at Mississippi State University developed an at-home, kitchen chemistry style laboratory to accompany the Survey of Organic Chemistry lecture course. The course featured 12 lab activities; eight hands-on experiences that focused primarily on important organic concepts including acid strength, extraction techniques, chromatographic…

Nuclear magnetic resonance (NMR) spectroscopy is the tool of choice for organic chemists to determine the molecular structure of organic molecules and, as a result, is a fundamental topic in the organic chemistry curriculum. A novel laboratory module has been developed to expand the scope of NMR spectroscopy beyond structure validation at the…

This study measures the effect of productive failure instruction in a digital inquiry environment on developing deep understanding and achievement of organic chemistry among Saudi Arabian secondary school students. The study adopted the experimental design of control and experimental groups with pre- and post-measurements. The sample comprised 66…

Scholarship animating both WAC/WID (Allan, 2013; Gere, et al., 2018; Hendrickson, 2016; Kells, 2007; Reid, et al., 2016) and STEM (Roth, 2003; Roth & Jornet, 2013; Tsui, 2007) has increasingly called for pedagogical attention to learners' lived, embodied experiences of knowing, writing, and becoming in and across disciplinary worlds. As one…

This study aimed to investigate the use of formative assessment rubrics for supporting the learning of organic chemistry in secondary schools in Rwanda. A mixed research approach was used to collect and analyze data. The target population was 210 senior five chemistry students and 15 chemistry teachers. However, 140 senior five chemistry students…

Heavy metals are a recognized toxic environmental contaminant, even at very low concentrations. There have been well-known events in the last decade within the US of high amounts of lead in the drinking water supplies of cities, leading to detrimental effects within its population. Ways have been found to remove this metal, and others, from water…

Reformed Experimental Activities (REActivities) is an innovative approach to the delivery of the traditional material in an undergraduate organic chemistry laboratory. To better understand the fidelity of implementing this pedagogy and what effects the framework of REActivities has on student-instructor interactions, an observational protocol…

Organic chemistry is the study of organic compounds containing hydrocarbons and their derivatives. It is similar to inorganic chemistry in terms of the cognitive model. However, the vast number of organic compounds has added to the difficulty in learning organic chemistry with compressed class hours in engineering majors. The integration of the…

In chemistry, building arguments and applying concept knowledge is closely linked to evaluating claims, supporting claims with evidence, and justifying the linkage of evidence to claim with reasoning. However, previous studies revealed that, when building arguments, students experience challenges either in differentiating between argument…

Gold is an increasingly prominent transition metal in organic synthesis. The air-stable, water-insensitive cationic gold(I) catalysts enable varieties of synthetic transformations with a simple reaction setup. However, this increased importance has not coincided with an increase in the application of gold in second-year organic chemistry courses.…

Stepped supporting tools were developed and used in the university seminar Organic Chemistry taken by nonmajor chemistry students, which supported self-regulated learning. These supporting tools were also used for accompanying homework, which included a QR code that led to additional supporting tools. The application of stepped supporting tools in…
