Students in introductory college physics often have wide ranges of preparation, making it challenging to deliver effective instruction for all. While numerous educational products and strategies have been shown to be broadly effective, there is a need for research-based online materials that support personalized learning and focus specifically on…

Self-regulated learning (SRL) is the metacognitive aspect of learning that goes beyond learning content and skills. With SRL, students are aware of their content understanding and learning progress and use advanced thinking skills to create goals and improve their academic achievement. In this action research, SRL strategies were integrated into…

Protein structure-function relationship serves as the primary learning outcome in any undergraduate biochemistry course. We expanded the protein structure-function exploration, PSFE initiative during COVID-19 to provide more effective and engaging experience to our undergraduates in biochemistry and independent research courses. Multiple…

In this laboratory exercise, students have an opportunity to evaluate the potential endocrine disrupting abilities of environmental chemicals of their choice using human cell culture. Over the course of 9 weeks, students learn how to aseptically handle and manipulate cells, perform and analyze a cytotoxicity assay and an enzyme-linked…

In this work, a simple rocking pendulum, in a circular arc shape, is presented. The idea is to put a rigid arc on a clean flat surface of glass and leave it to oscillate under the effect of a little impulse. Then, the periodic time of this arc pendulum's motion is experimentally determined. The mathematical analysis of the arc's motion is derived…

To promote student involvement in the reduction of chemical waste generated by teaching laboratories, a method published by Flinn Scientific for the treatment of waste sodium molybdate has been modified for use in treating waste generated by the popular molybdenum blue method for the analysis of phosphate in natural water samples. In this teaching…

Nonlinear chemical reactions produce interesting chemohydrodynamic patterns in an unstirred medium, which act as interesting demonstrations to display the novel phenomena in a nonequilibrium chemical system. Here, we report new outreach experiments: pH chemohydrodynamic patterns modulated by sodium polyacrylate in the bromate-sulfite-ferrocyanide…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

Research suggests that psychological factors are related to persistence in science, especially for underrepresented students; however, most psychological instruments have been validated through studies conducted at predominately White institutions. In the current study, we report reliability estimates for measures of science identity, science…

Many large introductory classes are taught in stadium-style classrooms, which makes group work more difficult due to the room layout and immobile seating. These classrooms may create challenges for an instructor who wants to monitor student engagement because the layouts make it difficult to interact with the students as they work. Student…

An inequitable distribution of resources and opportunities for marginalized students (i.e., opportunity gaps) leads to challenges in identifying effective study behaviors, metacognition, and academic help-seeking in higher education. While students benefit when these skills are taught explicitly through co-curricular workshops and courses, these…

Quantitative reasoning (QR) is a key skill for undergraduate biology education. Despite this, many students struggle with QR. Here, we use the theoretical framework of student noticing to investigate why some students struggle with QR in introductory biology labs. Under this framework, what students notice when given new information and data…

Group work is commonly adopted in university science laboratories. However, student small-group discourse in university science labs is rarely investigated. We aim to bridge the gap in the literature by characterizing student discourse group roles in inquiry-based science labs. The instructional context for this study was a summer program hosted…

This exploratory field study investigates the integration of innovative forms of recitation tasks in a first-year introductory mechanics course, focusing on smartphone-based experimental tasks alongside programming and standard recitation tasks. Smartphones, combined with external sensor modules, serve as a gateway enabling students to conduct…

Evidence suggests that students exposed to authentic undergraduate research activities are more successful than those who are not. Not all students in an undergraduate program get an opportunity for mentored research, which is still the popular way to expose them to authentic research. However, involvement in undergraduate research can be…
