Unlike the large number of laboratory experiments on phase-transfer catalysis (PTC) that focus on a catalyzed chemical process, the present laboratory emphasizes the mechanism of phase transfer catalysis itself. Students can follow visually the actual transfer of the reagent by the catalyst, and its consumption in the organic phase, in a…

Background: Cooperative and inquiry-based pedagogies provide a context for classroom discourse in which students develop joint understanding of subject matter knowledge. Using the symbolic interactionist perspective that meaning is constructed as individuals interact with one another, we examined how student groups enrolled in an undergraduate…

Laboratory practicals engage students in complex thinking to build their scientific knowledge and understanding. Surprisingly few studies connect the development of students' cognitive and metacognitive skills for learning in the laboratory practical with foundational skills for researching. Librarians strive to establish teaching partnerships…

Research-based science education (RBSE) is an instructional model that integrates scientific research with education by giving introductory-level undergraduate astronomy students an opportunity to do authentic research with real data. Its goals are threefold: (1) to teach that science is a process of discovery, not just a body of knowledge, (2) to…

The mathematical models that describe enzyme kinetics are invaluable predictive tools in numerous scientific fields. However, the daunting mathematical language used to describe kinetic behavior can be confusing for life science students; they often struggle to conceptualize and relate the mathematical representations to the molecular phenomena…

One way to encourage performance and persistence in STEM fields is to have students write about the utility value (UV) or personal relevance of course topics to their life. This intervention has been shown to increase engagement and performance in introductory courses. However, questions remain about the longevity of the effects and how best to…

A variety of factors contribute to attrition in science, technology, engineering, and mathematics (STEM) education at the community college level including underpreparedness, lack of confidence, and broader socioeconomic issues. This work describes our efforts to improve student learning and overall success in a community college General Biology I…

News media reports of scientific discoveries are often oversimplified, lacking nuance and context. As a result, citizens need both science literacy and information literacy skills to both decode the science content in a media report and track down the original scientific literature that prompted the media report. This article evaluates the…

The development and evaluation of a two-session laboratory class, based on Geneswitch technology and sex determination in the fruit fly Drosophila melanogaster, is described. Geneswitch system allows conditional control of gene expression. A laboratory exercise has been devised for sophomores in order to illustrate how Geneswitch technology can be…

At universities across the United States the epistemological beliefs of students have been observed to deteriorate after a semester of instruction in an introductory physics course. What this indicates is that after taking a course in physics most students, for example, may become less capable of delineating between evidence-based reasoning and…

Orbital Battleship, published in 2016 in this "Journal," is a hands-on competitive exercise which has been shown to be an efficient tool to reinforce the knowledge of the atomic structure. We decided to give it a more futuristic look and are presenting VR Orbital Battleship, a completely immersive collaborative experience which, in…

To be able to design a laboratory course it is important to know what laboratory skills students possess before the course starts. This way the course can focus on developing skills in areas that are lacking. Despite the extensive literature on laboratory education, there are few studies on what laboratory skills students have at this stage of…

This study explores the implications of a redesign of a college course that entailed a new partnership between a college neuroscience classroom and a high school. In this course, the college students engaged in original research projects which included conducting brain surgery and behavioural tests on rats. They used digital storytelling and…

This paper summarizes the author's experiences with transitioning from face-to-face to online General Chemistry Zoom sessions during the COVID-19 pandemic. The transition to online teaching during the COVID-19 pandemic was a Herculean task for instructors during Spring 2020. Instead of adapting completely new strategies for online teaching, the…

Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…
