General Chemistry I is known as a STEM (Science, Technology, Engineering, Mathematics) gatekeeper, often playing a role in determining students' STEM college pathways and their career prospects. However, there have been recent efforts to transform General Chemistry I from a gatekeeper course into a gateway course by implementing equity approaches.…

This study utilized the SEC (Survey of Enacted Curriculum) method to examine the alignment between Chinese high school chemistry curriculum standards (HSCCS) and the assessment of 'Chemical Reaction Principles' in the National College Entrance Examinations (NCEEs). The HSCCS and NCEEs were coded into two-dimensional matrices separately using SPSS,…

The problem addressed in this study was that some high school students do not have the math skills needed to succeed in a traditional chemistry class. If instructional strategies are not changed, many students who struggle with algebra will also struggle to master the chemistry content which is a required high school subject in Arizona. The…

Due to the difficulty of chemical compounds to visualize, augmented reality (AR) integrated with mobile learning has been developed as an alternative media for studying chemistry. This study aims to analyze the use of AR-integrated mobile learning in chemistry education from a bibliometric perspective in the last decade. A total of 225 articles…

In the field of education, ChatGPT has become a topic of debate for its usefulness as a learning tool. This article focuses on non-science majors' (n = 29) perceptions of a ChatGPT enabled final exam, where, prior to the exam, students wrote papers on science and sustainability and, during the final exam, students were asked to compare their paper…

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

The professional high school by the federal schools in Brazil requires an integrated curriculum itinerary. There is a lack of information about how to achieve that in a practical conception of integration. This article aimed to investigate the interdisciplinary approach of the content "transformation of energy" involving the relationship…

The ability of students' creative thinking is not well developed by learning that only focuses on convergent thinking training without giving students problems to face. Therefore, students have difficulty in developing creative thinking ability. Therefore, it is necessary for a learning program to improve student creative thinking ability. This…

The American Association for the Advancement of Science (AAAS) has outlined four themes that define science literacy; these are systems, models, constancy and change, and scale. More recently, the National Research Council has released the framework for K-12 science education that includes "Scale, Proportion, and Quantity". Scale…

A laboratory experiment for the determination of the cross-linking density of silicone elastomers is described on the basis of swelling experiments and mechanical tests. In the experiment, the macroscopic swelling and mechanical behaviors of the elastomers were discussed as a function of the cross-linking density, which can be easily controlled by…

Flavor plays a crucial role and is the most important aspect of foods and beverages. [Beta]-Ionone is a common flavor compound with a characteristic violet-like odor. An undergraduate flavor compounds chemistry laboratory that provides preparation and characterization of the flavor compound inclusion complex between…

In this laboratory experiment, students apply a mass-based approach to determine the Henry's law constant for CO[subscript 2] using a small bottle of a diet carbonated beverage. The calculations are challenging; therefore, team-based learning is encouraged. Our students reported values of 0.033 ± 0.003 mol/(L[middle dot]atm) at room temperature…

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at the core of a student's scientific literacy, scale or the skills related to understanding quantity…

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.…

Molecular orbital diagrams are commonly taught and used for describing chemical bonding chemistry courses including courses at the college level. Misconceptions that occur when students construct and/or use these diagrams are difficult to anticipate, diminish the diagram utility, and limit student learning. In this exploratory study, a combination…
