Project-based learning (PBL) instructional methods attempt to make connections between students and their ability to solve real problems. We framed our qualitative study within sociocultural theory and used the Strengths, Weaknesses, Opportunities, and Threats (SWOT) model to define the positive and negative factors occurring during a PBL…

The sudden transition from in-person to virtual learning during the spring 2020 semester posed challenges for students and faculty alike. This paper explores the techniques used by faculty to transform the chemistry and biochemistry curriculum at a Hispanic-serving institution with a significant proportion of first-generation students and the…

Machine learning algorithms have recently been used to predict students' performance in an introductory physics class. The prediction model classified students as those likely to receive an A or B or students likely to receive a grade of C, D, F or withdraw from the class. Early prediction could better allow the direction of educational…

This reflection looks at pedagogic strategies employed in General Chemistry classes for English Language learners (ELLs) in a rapid response to the COVID-19 pandemic. The approaches included the use of small group systems thinking (ST) activities and a variety of formative assessments geared toward maintaining and enhancing students' language…

Over the past 25 years, the Davidson College Physics Department has developed small computer programs called Physlets. These programs were written in Java and distributed as Java applets embedded in HTML pages. Physics teachers from around the world used Physlets to author interactive computer-based curricular materials for the teaching of…

The American Association for the Advancement of Science (AAAS) strongly recommends that "science be taught as science is practiced." This means that the teaching approach must be consistent with the nature of scientific inquiry. In this article, the authors describe how they added scientific inquiry to a large lecture-based physiology…

Poggendorff showed experimentally, in the middle of the 19th century, that the weight of an Atwood machine is reduced when it is brought to motion. His experiment has been revisited from time to time, making use of instrumentation that reflects the technological development of the moment. In this paper, the evolution of the experiment is briefly…

This column provides original articles on innovations in case study teaching, assessment of the method, as well as case studies with teaching notes. This month's issue discusses using case studies to test for knowledge or lessons learned.

Although recognizing prefixes in physical quantities is inherent for practitioners, it might not be inherent for students, who do not use prefixes in their everyday life experiences. This deficiency surfaces in AP Physics exams. For example, readers of an AP Physics exam reported "a common mistake of incorrectly converting nanometers to…

Due to a lack of time and, thus, an inability to present every possibility in a chemical reaction, organic chemistry professors tend to present each reaction with a single outcome. In practice, this is clearly not the case. A first-semester, three-week laboratory experiment designed for undergraduate organic chemistry students is described in…

A three-day ethics seminar introduced ethics to undergraduate environmental chemistry students in the Research Experiences for Undergraduates (REU) program. The seminar helped students become sensitive to and understand the ethical and values dimensions of their work as researchers. It utilized a variety of resources to supplement lectures and…

The objective of this paper is to present a laboratory experiment that explains the phenomenon of sinking in quicksand simulated as a fluidized bed. The paper demonstrates experimentally and theoretically that the proportion of a body that sinks in quicksand depends on the volume fraction of solids and the density of the body relative to the…

This commentary explores theoretical alternatives for viewing the problem identified by Volny Fages and Virginie Albe in their article entitled Social issues in nanoscience and nanotechnology Master's degrees: The socio-political stakes of curricular choices. An approach to social research is suggested that would render visible the associations…

Although peer interaction in the college classroom may benefit some students by developing peer networks for future collaborations, prior research has suggested that these relationships most often benefit students from overrepresented communities, while minoritized student populations may gain less from these experiences. In this article, we…

This article presents the structure of the organic chemistry laboratory Course "Synthesis and Extraction of Drugs" that is included in Modena University (Italy) in the third year of the five-year "Chemistry and Pharmaceutical Technologies" degree program. This course is unique in its kind, and it aims to provide students with…
