The laboratory experiment regarding esterification of ethylene glycol with acetic acid to ethylene glycol diacetate using resin catalysts in a continuous flow was designed to carry out the reaction in a flow through an inquiry-guided approach. Incorporating the burgeoning field of continuous flow chemistry into the educational infrastructure, the…

Clathrate hydrates are attractive materials for education because they form from water and familiar compounds, such as carbon dioxide, and are relevant to novel technologies. In this study, an attempt to propose a laboratory experiment was summarized, which used carbon dioxide clathrate hydrate as an educational material with carbon capture…

Practical experiments enhance students' understanding of basic concepts and promote deep learning experiences in chemistry. The smartphone application of Lab4Chemistry was utilized to replace colorimeters with smartphone camera sensors. Low-cost and readily available materials, including anthocyanin (fresh red cabbage) and common kitchen…

Aim/Purpose: The study seeks to utilize Augmented Reality (AR) in creating virtual laboratories for engineering education, focusing on enhancing teaching methodologies to facilitate student understanding of intricate and theoretical engineering principles while also assessing engineering students' acceptance of such laboratories. Background: AR, a…

Laboratories are considered to play a unique role in circuits teaching. Laboratories can be traditional, with physical components and desks, or virtual with graphical simulators. Applying these facilities in teaching, students can make experiments or measurements by exploring electric circuits' features. However, an intriguing research question is…

The literature on laboratory objectives in engineering education research is scattered and inconsistent. Systematic literature reviews identified the need for better understanding. This paper ranks the laboratory learning objectives across the cognitive, psychomotor and affective domains to improve scaffolding. It provides an opportunity for…

Chemical engineers must learn to connect concepts across vastly different scales, spanning from molecular structures to industrial processes. Here, we explore the use of a virtual-reality simulation with a companion video of an experiment to help undergraduate students connect nanoscale fundamentals to macroscale engineering observations.

In a 1984 essay, Benjamin Bloom, an educational psychologist at the University of Chicago, asserted that tutoring offered "the best learning conditions we can devise" and that tutors could raise student achievement by two full standard deviations--or, in statistical parlance, two "sigmas." The influence of Bloom's two-sigma…

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 the article "It's Just an Observation," Robinson and Wainer (Educational Psychology Review 35, Robinson, D., & Wainer, H. (2023). It's just an observation. Educational Psychology Review, 35(83), Published online: 14 August, 2023) lamented that educational psychology is moving toward the dark side of the quality continuum, with…

In primary organic chemistry, students learn about the dehydration of ethanol to ethylene with concentrated sulfuric acid. Similar reactions(the dehydration of alcohols) exist in nature. For example, various alkenes with aromas are synthesized from linalool, a monoterpene tertiary alcohol. In this laboratory experiment, we report experiments…

In this second-semester organic chemistry lab experiment, students work collaboratively using a combination of chemical synthesis and NMR spectroscopy to investigate the diastereoselectivity associated with the Meerwein-Ponndorf-Verley (MPV) reduction of two ketone substrates having carbonyl groups flanked by an [alpha]-chiral carbon with…

The variation in the transference number of H[superscript +] (aq) is investigated for different HCl solution concentrations. The method for scribing graduations on electromigration tubes is modified to decrease the error in experimental measurements, and metallic copper is used as the anode to reduce the toxicity and environmental impact of the…

Nearly everyone, including physics students, finds rainbows to be fascinating and much has been written about them. For example, in a 2020 paper, Kenneth Ford sets forth the basic theory of rainbows created by water droplets at the level of geometric optics and uses a graphical approach to address the question of the relative intensities of the…

The proposed experiment will examine the effect of deceptive behavior on memory. Participants will be assigned to a "strong-incentive to cheat" or "weak-incentive to cheat" condition and play the adapted Sequential Dyadic Die-Rolling paradigm. Specifically, Player A (computer; participants think it is another participant)…
