The proliferation of remote laboratory instruction increased substantially during the recent global pandemic. Many physics departments implemented this rapid transition without the previous experience, time, and deliberation to optimize learning experiences for students. The present quasi-experimental, nonequivalent group design study examined…

The current dropout rate in physics studies in Germany is about 60%, with the majority of dropouts occurring in the first year. Consequently, the physics study entry phase poses a significant challenge for many students. Students' stress perceptions can provide more profound insights into the processes and challenges during that period. In a panel…

Cancer databases collect original cancer studies and patient clinical information into one site that allows for global analysis. While many courses focus on cancer, few utilize these powerful cancer databases. Our goal was to create a lab experience in which students could explore original cancer study databases, looking at the expression and…

Up to now, support for the idea that a controlled component exists in creative thought has mainly been supported by correlational studies; to further shed light on this issue, we employed an experimental approach. We used four alternate uses tasks that differed in instruction type ("be fluent" vs. "be creative") and concurrent…

A national survey on chemistry instructional laboratories was administered to faculty members at four-year postsecondary institutions in the United States for the purpose of exploring levels of inquiry-based instruction implemented in laboratory courses. Respondents were asked to rate the level of choice their students had in deciding six key…

In an era where technology is being used more and more in daily life, the potential and effective use of technology is becoming increasingly vital in education. Engineering education necessitates the use of technology to assist students in understanding abstract concepts and principles. Augmented reality (AR) is a technology that can be used to…

With the advancements in broad-spectrum sunscreens and the recent bans on benzene-based sunscreens due to their environmental toxicity, there has been a push toward broad-spectrum sunscreens containing in organic active ingredients. In this study, a procedure was developed to analyze the particle size and size distribution of inorganic active…

The study of neuroanatomy imposes a significant cognitive load on students since it includes huge factual information and therefore demands diverse learning strategies. In addition, a significant amount of teaching is carried out through human brain demonstrations, due to limited opportunities for cadaveric dissection. However, reports suggest…

A physical organic chemistry experiment is described for second-year college students. Students performed nucleophilic aromatic substitution (NAS) reactions on 5,10,15,20-tetrakis(2,3,4,5,6-pentafluorophenyl)porphyrin (TPPF[subscript 20]) using three different nucleophiles. Substitution occurs preferentially at the 4-position ("para")…

Active learning is widely recognized as superior to traditional passive, lecture-based techniques for fostering learning in STEM courses. Interactive, hands-on learning where students interact with their peers and physical systems is an effective type of active learning. As the need for scientists and engineers continues to grow, understanding and…

The purpose of this study is to determine the time management behaviours before starting experiments in the laboratory environment and to find out whether such behaviours are influential on academic achievement in the laboratory course. Nine pre-service science teachers were observed for 9-11 minutes per week before starting experiments for 6…

Contribution: This article provides evidence that perceived learning has a relationship and influences the way students evaluate laboratory experiments, facilities, and demonstrators. Background: Debate continues on the capability and/or reliability of students to evaluate teaching and/or learning. Understanding such relationships can help…

The so-called Diet Coke and Mentos experiment is initiated by dropping Mentos candies into a bottle of Diet Coke or other carbonated beverage. This causes the beverage to rapidly degas, causing foam to stream out of the bottle. Simple application of the gas laws leads to the straightforward prediction that ejection of greater foam volume is…

A new undergraduate inorganic chemistry laboratory experiment is presented. An introduction of the spectrochemical series and ligand exchange is explored using the coordination complex dirhodium tetraacetate, Rh[subscript 2](OAc)[subscript 4]. Students have measured the absorption spectra of the Rh[subscript 2] complex in the presence of various…

In five experiments, we examined the conditions under which participants remembered true and false information given as feedback. Participants answered general information questions, expressed their confidence in the correctness of their answers, and were given true or false feedback. In all five experiments, participants hyper'corrected' when…
