The challenge of accurately assessing critical thinking in physics education, particularly on topics like work and energy, remains a key issue for educators. The current study aims to address this challenge by exploring students' critical thinking abilities using two-tier test data analyzed through the Rasch model. Data were collected from…

Molecular School (MS) is an extracurricular initiative intended to show relevant and complex concepts of chemical sciences to precollege students. The main goal is to motivate the participants to expand their awareness of chemical sciences and to acknowledge its relevance in everyday life, in order to stimulate the students to engage in chemistry…

Surface chemistry is a challenging realm for most students because of its abstract nature and numerous associated mathematical equations. Herein we report a set of dedicated sequential inquiry-based learning (IBL) activities enriched with virtual laboratory learning and hands-on instructions. The activities were intended to help students grasp…

Although science education, including biochemistry and molecular biology education, starts before students commence university, for many students, undergraduate programs are their first real introduction to biochemistry and molecular biology. Students often report that biochemistry and molecular biology are relatively difficult topics hence the…

Radical chemistry is an essential part of the organic chemistry curriculum. Free radical halogenation experiments provide an excellent opportunity to introduce important topics related to the outcome and mechanism of organic reactions. In this communication, a green photochemically activated benzylic bromination of p-toluic acid is described. In…

Capstone teaching laboratory activities can serve as a crucial part of the undergraduate learning experience. With this in mind, a laboratory activity that combines synthesis and multiple characterization techniques has been developed for an upper-division, laboratory-based inorganic course. Complexes of Cu(II) and Ni(II) of the amino acid glycine…

A practical experiment is described to estimate the distance to a star using simple equipment, suitable for secondary or undergraduate students. The brightness of the star is visually matched to a miniature filament lamp, and its distance inferred from the inverse square law. Students gain an appreciation of astronomical units and practice in…

The effects of kinetic vs thermodynamic control on "endo"/"exo" stereoisomer ratios can be observed in a simple Diels-Alder reaction between "N"-phenylmaleimide and furan. The use of microwave-promoted synthesis affords the cycloadducts in yields ranging from 65-100%, employing reaction times of 1-10 min at…

Instrumentation plays a vital role in almost every area of chemistry. As such, it is imperative that the undergraduate curriculum is designed to allow students to have opportunities to use a variety of instruments to best prepare them for careers in chemistry. Previous work has provided evidence of the types of instruments students use in…

The importance of introducing computational approaches early and actively in science education is widely acknowledged among educators and scientists. Many great ideas have been put forward and implemented by advocates and organizations such as Partnership for Integration of Computation into Undergraduate Physics (https://www.compadre.org/PICUP)…

We propose cross-disciplinary learning as a construct that can guide instruction and assessment in programs that feature sequential learning across multiple science disciplines. Crossdisciplinary learning combines insights from interdisciplinary learning, transfer, and resources frameworks and highlights the processes of resource activation,…

The process of method development is at the heart of analytical chemistry, yet direct experimental experience with the process is rarely taught in the undergraduate laboratory. We report here an experiment that uses rapid, safe, and inexpensive paper-based microfluidics with cell phone detection in order to facilitate the development of a…

Simple, often artificial problems are normally preferred for introductory lab courses and are restricted to indoor participation. Microtitrations make it possible to leave the lab and study water chemistry directly in the natural environment. An exemplary outdoor challenge is presented here: travertine formation is context-rich, has to be examined…

Collaborative learning methods are increasing in popularity as a way of improving student performance and involvement in undergraduate courses. For this study, a group quiz format was used in an attempt to improve course grades and engagement in an introductory meat science course. Six group quizzes and six individual quizzes were taken by 70…

Although principles and practices of green and sustainable chemistry have been articulated for more than 20 years, they have yet to become systemically infused into the undergraduate chemistry curriculum. The American Chemical Society Green Chemistry Institute (ACS GCI) has convened stakeholders from across the chemistry education community to…
