A mobile application game has been adapted to teach students about laboratory instruments, glassware, apparatus, and techniques. The game was designed with reference to a popular icebreaker game, "Charades!", to ensure that it was easily accessible to students. Students will hold a mobile phone just above their forehead, which will then…

The study assessed effects of problem-based learning approach on senior secondary school students' practical skills in chemistry and the role of school type as a moderating variable. A pretest, posttest control group quasiexperimental setting with non-equivalent groups design was adopted. A total of 124 students (54 from coeducational and 70 from…

Explain Everything is an interactive, user-friendly, and easily accessible app for mobile devices. The interactive app-based teaching methods discussed here can be adopted in any STEM or non-STEM course. This app allows instructors to take advantage of both the chalkboard and PowerPoint slides on a single platform, create videos for lecture…

Mobile technology is increasingly prevalent in higher education. Chemistry-related software applications (apps) on touchscreen computers are emerging as a popular platform in many areas, including in the chemistry classroom. In this work, a new game-based app designed for hand-held and portable touch-controlled devices is presented. Chirality-2…

iSchlenk, a portable instructional cart with equipment for hands-on student experience in safe handling of air-sensitive, moisture-sensitive, toxic, pyrophoric, and/or radioactive chemical materials, is described. The cart, for use by =4 students, has compressed air and vacuum from a diaphragm vacuum pump supplied to 4 three-port Schlenk lines…

The present paper offers a competency-based approach to evaluate high school laboratory skills during a chemistry course. The "Secretaría de Educación Pública" (Mexico's Ministry of Education) has identified experimental sciences specific competencies that are to be established in high school. This study investigated the following…

The appreciation and understanding of gas generation through processes is vital in biochemical education. In this work, an augmented reality tool is reported to depict the redox reaction between hydrogen peroxide and sodium hypochlorite solutions, two ubiquitous oxidizing agents, to create oxygen, a combustible gas. As it operates out of…

Instructional technologists and faculty in post-secondary institutions have increasingly adopted learning analytics interventions such as dashboards that provide real-time feedback to students to support student' ability to regulate their learning. But analyses of the effectiveness of such interventions can be confounded by measures of students'…

The present study determined the perceptions of pre-service teachers on utilizing productive lesson study as a framework in teaching high school chemistry. Participants of the study were thirty (30) junior pre-service chemistry teachers from a state-funded teacher education institution in Manila, Philippines. Participants were exposed to a…

This paper presents a case study that investigated students' perceptions on the integration of a socio-scientific issue into a general chemistry course at a public university located in northwestern California. The teaching intervention is based on a digital learning environment structured by the software Prezi that students used to explore the…

Thin-layer chromatography (TLC) is one of the basic analytical procedures in chemistry and allows the demonstration of various chemical principles in an educational setting. An often-overlooked aspect of TLC is the capability to quantify isolated target compounds in an unknown sample. Here, we present a suitable route to implement quantitative…

Recent articles in this "Journal" have advocated for focusing instruction on core ideas of the discipline and moving assessment beyond content knowledge to also eliciting evidence about what students can do with their knowledge. Yet, the deep connected learning supported by this kind of instruction and assessment requires students to…

Experiments in pubs? Teaching chemical associations between beer and cola and arousing interest in science? Such a thing is possible in a place that at first sight seems very unorthodox as an out-of-school learning and teaching location. With the innovative scientific communication format "PubScience--The Long Night of Experiments",…

This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

In this study, we explore the issues and challenges involved in supporting students' learning to discern relevant and critical aspects of determining oxidation states of atoms in complex molecules. We present a detailed case of an interaction between three students and a tutor during a problem-solving class, using the analytical tool of practical…
