This paper provides two demonstrations of how Augmented Reality (AR), which is the projection of virtual information onto a real-world object, can be applied in the classroom and in the laboratory. Using only a smart phone and the free HP Reveal app, content rich AR notecards were prepared. The physical notecards are based on Organic Chemistry I…

A 3-week module incorporating the principles of green chemistry was developed for a large-enrollment, introductory organic chemistry laboratory course. An emphasis was placed on students planning their own experiments with the goal of obtaining a greener reaction (week 1). Students executed their designed experiments in week 2 and were given an…

The cannon boring experiment of Count Rumford, where eight kilograms of water were boiled by metal on metal friction, is investigated. Consideration of this dramatic demonstration can enrich classroom discussions of calorimetry, units of measure, elements, and thermodynamics. A section pertaining to use of the article in the classroom appears…

A hands-on experiment to obtain atomic and ionic radii with lumps of metal and ionic compounds is reported here. The experiment is performed with industrial-grade typical metals (iron, copper, aluminum, and lead) and single-crystal lumps of ionic compounds (sodium chloride, potassium chloride, and potassium bromide). Students measure the dimension…

Here, students determine the total phenolic content in beers using the Folin-Ciocalteu assay. The Folin-Ciocalteu reagent is a yellow complex, in an alkaline medium; it reacts with phenols and non-phenolic reducing substances to form a blue complex. Quantitative analysis was carried out using absorbance measured at 765 nm (standard method) and…

This study analyzed representations of practical work in 10th grade chemistry textbooks and associated experimental workbooks from different Chinese communities. In the field of textbook research, science education textbooks research is unbalanced between regions. In the case of chemistry textbooks analysis within the Chinese context, textbook…

Increasing demand for chemicals worldwide, depleting resources, consumer pressure, stricter legislation, and the rising cost of waste disposal are placing increasing pressure on chemical and related industries. For any organization to survive in the current arena of growing climate change laws and regulations, and increasing public influence, the…

Collaborations and partnerships across disciplines are becoming increasingly recognized as valuable endeavors toward solving emerging global challenges in our rapidly changing world. Thus, it is crucial to create STEM educational strategies that infuse diverse and interconnected perspectives among scientists, policymakers, and the general public.…

One of the keys to achieving the United Nation's Sustainable Development Goals (SDGs) in education is to introduce novel pedagogical strategies into university curricula in order to promote an enhanced acute sense of sustainability in future professionals, teachers, and decision-makers. This paper aims at analyzing the effectiveness of including…

Quasi-experiments are common in studies that estimate the effect of instructional interventions on student performance outcomes. In this type of research, the nature of the experimental design, the choice in assessment, the selection of comparison groups, and the statistical methods used to analyze the comparison data dictate the validity of…

Numerous online resources provide a variety of content for a wide range of STEM topics; however, they tend to function as isolated tidbits that provide content-specific knowledge. Application-based science education videos address the overlooked issue of concept to application by implementing experimental components in their videos and fostering…

Although the content of science lessons has been analyzed from different perspectives by developing a set of codes (e.g., K. J. Roth, S. L. Druker, H. E. Garnier, M. Lemmens, C. Chen, T. Kawanaka, and R. Gallimore, (2006), Teaching science in five countries: results from the TIMSS 1999 video study, Washington, DC: National Center for Education…

Variation in marks awarded, alongside quality of feedback, is an issue whenever large-scale assessment is undertaken. In particular, variation between sessional teaching staff has been studied for decades resulting in many recorded efforts to overcome this issue. Attempts to curtail variation range from moderation meetings, extended training…

This paper presents the findings of a three-year longitudinal study (Grades 9-11; N = 756 students in German secondary schools; mean starting age = 14.7 years) that explores the development of and the interplay between upper-secondary students' individual interest and conceptual understanding in chemistry. Students' individual interest was…

The Peer-Led Team Learning (PLTL) and the Science Writing and Workshop Template (SWWT) are two active learning instructional approaches which combine writing, inquiry, collaboration, and reflection, elements which have been associated with critical thinking development. In this study, we used a quasi-experimental pretest-post-test design to…
