This study investigates the impact of utilizing dynamically linked concrete and abstract representations of objects in modern, virtual electric circuit laboratories on the cognitive evolution and the representational fluency of high school students. The students (N = 27, aged 16-17) were randomly divided into two classes: the first class used a…

Rovibrational spectroscopy is a fundamental component of most physical chemistry curricula. This article describes an adaption of the rovibrational spectroscopy of carbon dioxide experiment that can be used as a stand-alone experiment or in conjunction with a traditional hydrogen chloride experiment. The case is made that the laboratory…

Instruction on the design of analytical instrumentation is a critical component of the analytical chemistry curriculum. To simplify this process and enable students to directly see how the instruments that are in their own laboratory setting work, the use of augmented reality technology can be implemented. In this report, the "HP Reveal"…

Elementary and middle school science curricula typically focus on generating an interest in science and engineering through the use of hands-on activities that demonstrate specific concepts. Laboratory activities designed in this manner often circumvent some of the main challenges that engineers and scientists face, namely balancing advantages and…

How students behave and learn in the teaching laboratory is a topic of great interest in chemical education, partly in order to justify the great expense of teaching laboratories. Much effort has been put into investigating how students think, feel and physically act in these unique learning environments. One such attempt was made through the…

Contribution: Prior studies indicate that students experimenting with characterization of optical planar waveguides use expensive ready-made prism couplers without clear understanding about construction of the entire optical measurement system. This paper presents a cost-effective modified bright-mode prism coupler that helps students learn…

Purpose: Although critical thinking skills (CTS) and scientific process skills (SPS) are the beneficial skills needed in the 21st century learning, the fact is that the acquisition of these two skills is still low. Research with a focus on improving these skills by using inquiry-based approach is also limited. Therefore, this quasi-experimental…

Diagnostic molecular biology is a fast developing discipline of laboratory medicine widely used in numerous medical branches such as oncology, hematology, immunology, internal medicine, or infectious diseases, which will certainly have a major impact on clinical medicine in the near future. Nowadays, educational process is forced to face the…

Recent advances in computer hardware and algorithms are spawning an explosive growth in the use of computer-based systems aimed at analyzing and ultimately correlating large amounts of experimental and synthetic data. As these machine learning tools become more widespread, it is becoming imperative that scientists and researchers become familiar…

Practical training in the dissection of human cadavers is a fundamental and traditional component of human anatomy education in medical schools. This practice, however, can be stressful for students and can generate a certain amount of anxiety. The aim of this study is to explore the attitudes, reactions, and anxiety levels of first-year medical…

This study explores how gender and race intersect to shape graduate students' experiences in academic workspaces using in-depth interviews with 67 biology PhD students. Building on recent intersectional research, our study highlights ways that race and gender create inequality in graduate education. Extending previous research on faculty, we…

Fluorescence quenching is an analytical technique and a common undergraduate laboratory exercise. Unfortunately, a typical quenching experiment requires the use of an expensive fluorometer that measures the relative fluorescence intensity of a single sample in a closed compartment unseen by the experimenter. To overcome these shortcomings, we…

The purpose of this study was to understand the impact, implementation and costs associated with a one-semester elective lab course in 9th grade, Accelerating Literacy for Adolescents (ALFA) Lab, which seeks to improve students' reading achievement, particularly for those from economically disadvantaged communities. This study used three cohorts…

Online prelaboratory videos and quizzes were prepared for all experiments in CHEM 231, Organic Chemistry I Laboratory. It was anticipated that watching the videos would help students be better prepared for the laboratory, decrease their anxiety surrounding the laboratory, and increase their understanding of the theories and concepts presented.…

This paper reports a laboratorial internship included in the Portuguese Science and Technology promotion program "Internships for Young People in Laboratories (Ciência Viva no Laboratório)", which provided high school students an opportunity to approach the reality of scientific and technological research in a higher education…
