In today's world, remote-controlled robots are widely used across various industries due to their ability to enhance working efficiency in various applications. Learning about robot operation and human-computer interaction has emerged as a popular topic in recent times. Indeed, learning robotics can be challenging for many students as it requires…

In this article, we describe curricular materials developed to engage undergraduate students in evolutionary thinking around antibiotic resistance using the MEGA-plate experiment (Microbial Evolution and Growth Arena). This elegant and visual experiment, developed by the Kishony Lab, shows the development of antibiotic resistance on the timescale…

Recent advancements in large language models (LLMs) hold significant promise for improving physics education research that uses machine learning. In this study, we compare the application of various models for conducting a large-scale analysis of written text grounded in a physics education research classification problem: identifying skills in…

The Internet of Things (IoT) is a network of objects that can exchange data with other devices also connected to the Internet. One of the most common consumer examples of IoT is home automation, as a variety of smart devices, including doorbells, lightbulbs, thermostats, and refrigerators are now available which users can control remotely using…

This project aims to understand physics faculty responses to transitioning to online teaching during the COVID-19 pandemic. We surveyed 662 physics faculty from the United States following the Spring 2020 term; of these, 258 completed a follow-up survey after the Fall 2020 term. We used natural language processing to measure the sentiment scores…

A green laboratory experiment has been developed in which students perform an aqueous oxidation/cycloaddition reaction to convert salicyl alcohol into a pentacyclic diepoxydione that is readily isolated by filtration. Drawing on their knowledge of periodate-mediated 1,2-diol cleavage, students propose a mechanism for the oxidation of salicyl…

Due to the COVID-19 pandemic, social distancing restrictions are in place in most public settings, and the undergraduate laboratory is no exception. In order to accommodate social distancing requirements, many laboratory exercises are being redeployed in an online format, which deprives students of experiential learning opportunities in a real…

This paper explores the experience of how Chinese international doctoral students develop critical thinking. Narrative interviews are conducted. Narrative thematic analysis is adopted. Four big themes are generated, which are understanding of critical thinking, comparison and contrasts, factors contributing to development of critical thinking and…

The case study approach provides students with a better appreciation of how scientists solve problems and conduct themselves in the "real world". When applied to the undergraduate chemistry laboratory, this approach also challenges critical thinking skills and creativity in ways "cook book" experiments very often do not. This…

This account reports building a community of practice for organic chemistry instructors. With support from Chemistry Collaborations, Workshops, and Communities of Scholars (cCWCS), a group of organic chemistry faculty facilitated multiple workshops to introduce active learning techniques to their colleagues across the country. A Web site,…

Integrating authentic research-based experiences that mimic real-world scientific practices and relevance to student personal life into a chemistry curriculum can make abstract chemical principles more palpable to students. Unfortunately, many reported research-based experiences chemistry laboratory experiments lack relevance to a student's…

The study aimed to determine the effects of students teams achievement divisions (STAD) and reading-writing-application (RWA) methods on teacher candidates' academic achievements, laboratory attitudes, cooperative work, laboratory safety and scientific process skills in science teaching laboratory practice-I courses. In the research, a…

Perovskite solar cells have garnered exponential research interest due to their facile fabrication, solution processability, and low cost. However, there have been limited efforts to integrate this class of materials into the undergraduate laboratory curriculum. Therefore, we designed an integrated laboratory experiment in our upper-division…

Traditional, template physics labs are often associated with student dissatisfaction and superficial applications, and are known to leave students with fragmented knowledge. An alternative known as labatorials, a conceptually driven approach to labs, has been proposed. In a number of studies, labatorials have been shown to work well. However, what…

Students find it hard to understand acid-base homeostasis and the mechanisms involved in compensating for acid-base imbalances, including the role of the lungs and kidneys in this process. We have developed a laboratory activity based on collaborative problem-based learning and human patient simulators (HPSs) to teach this topic. Students (n=50)…
