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 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…

The science laboratory learning environment has been a distinctive area in science education since the 19th century. Unfortunately, students are generally not aware of what science instructors expect from laboratory experiences, and far too often, the undergraduate science laboratory curriculum lacks explicit, well-defined goals. Science…

The ability to accurately reason using three-dimensional visualizations is vital to success in STEM disciplines, particularly the geosciences. One impediment to learning from visualizations is spatially-based misconceptions. Such errors can arise from a range of sources (e.g., prior beliefs, inaccurate application of analogy, and visual…

Contribution: This article aims to explore learner variables that predict the effectiveness of university class using the Havruta method. Background: This article was conducted on 105 learners enrolled in the "General Physics and Experiments 2" class at K University in South Korea. Research Questions: Independent and dependent variables…

Previous research has noted one's knowledge of and attitudes toward the theory of evolution is negatively predicted by one's political ideology, specifically how conservative the individual identifies, and positively predicted by one's level rational thinking. The present research expands on this past research by examining the roles of political…

In selecting from a repertoire of traditional kinetics experiments, an instructor often has to choose among having students gain experience with the graphical method, the method of initial rates, or a temperature-dependent experiment in which students construct an Arrhenius plot. This paper presents an environmentally friendly bleaching reaction…

The ability of students to understand the relationship between genotype and phenotype, and the mechanisms by which genotypes and phenotypes can change is essential for students studying genetics. To this end, we have developed a four-week laboratory called Blue Genes, which is designed to help novice students discriminate between two mechanisms by…

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")…

Proper hand hygiene accompanied with environmental surface disinfection provides a comprehensive approach to control and prevent respiratory and gastrointestinal illness in schools, hospitals, work environments, and the home. The persistent non-pathogenic Nora virus common in "Drosophila melanogaster" provides a horizontally transmitted…

A vectorial representation of the full sequence of events occurring during the 2D-NMR heteronuclear single-quantum correlation (HSQC) experiment is presented. The proposed vectorial representation conveys an understanding of the magnetization evolution during the HSQC pulse sequence for those who have little or no quantum mechanical background.…

To provide a research-like experience to upper-division undergraduate students in a biochemistry teaching laboratory, isothermal titration calorimetry (ITC) is employed to determine the binding constants of lysozyme and its inhibitors, N-acetyl glucosamine trimer (NAG[subscript 3]) and monomer (NAG). The extremely weak binding of lysozyme/NAG is…

A two-part laboratory exercise was developed to enhance classroom instruction on the significance of p53 mutations in cancer development. Students were asked to mine key information from an international database of p53 genetic changes related to cancer, the IARC TP53 database. Using this database, students designed several data mining activities…

We describe here a collective and experimental research project-based learning (ERPBL) for master's students that can be used to illustrate some basic concepts on glucose/lipid homeostasis and renal function around a topical issue. The primary objective of this ERPBL was to strengthen students' knowledge and understanding of physiology and…

The current study examines the performance and achievement of students in the Systematic Qualitative Analyses of Cations (SQACs). We sought answers to questions such as, "What are the students' levels of performance?" and "What is the relation between the average scores for performance and achievement?." This was done by using…
