Background: Differences in post-secondary academic outcomes along dimensions of gender, race/ethnicity, and socioeconomic status are a major concern. Few studies have considered differences in patterns of academic outcomes and underlying mechanisms driving disparities across different STEM disciplines. Using data from about 4000 undergraduates in…

This study investigated the time effect of cooperative games on students' emotions of learning science and the treatment effect on their chemistry achievement. This quasi-experimental study compared the use of cards, board games, and riddles, and the use of conventional paper-and-pencil exercises to learn the basics of chemical elements and…

Using the identity lens as a theoretical framework, we studied 42 novice second career chemistry teachers, who had previously worked as chemists and participated in an alternative certification program (ACP) at a science and engineering research university. Our goal was to understand the transition process of these teachers into the teaching…

Spatial ability is an important tool in chemistry and this ability can be improved. Various technologies have been used to improve spatial ability. However, it is not clear if viewing technologies should take the place of the model kit; the traditional method of learning about molecular structures. Our research aims to address this gap. In our…

This study aims at determining the effect of the pedagogical technique most frequently used while implementing the competency-based curriculum (CBC) in teaching chemistry in senior two (S2) classes (age range 14-16) and the teachers' alignment with the scheme of work. It was conducted in 10 selected Rwandan secondary schools using a teacher…

This paper describes the development and implementation of GAPc, a gamification project in chemistry. GAPc is an online active student-centered remedial teaching tool allowing prospective and enrolled students to electronically assess their knowledge of basic and advanced chemistry concepts via different game levels of expertise. This provides…

Most junior high school students considered chemistry as a complicated science subject with an abstract concept, symbols, and terms that must be memorized. The difficulty of learning chemistry made students had low positive perceptions of chemistry. It was needed the right ways to introduce chemistry to them. The purpose of the multiple case study…

Orbital Battleship, published in 2016 in this "Journal," is a hands-on competitive exercise which has been shown to be an efficient tool to reinforce the knowledge of the atomic structure. We decided to give it a more futuristic look and are presenting VR Orbital Battleship, a completely immersive collaborative experience which, in…

To be able to design a laboratory course it is important to know what laboratory skills students possess before the course starts. This way the course can focus on developing skills in areas that are lacking. Despite the extensive literature on laboratory education, there are few studies on what laboratory skills students have at this stage of…

The study was conducted to compare the performance of students working in chemistry laboratory with those working in chemistry laboratory supplemented with simulations at secondary school level. The study was experimental in nature and post-test only control group design was used. The sample comprised of 55 males and 60 female students and 02…

This study aims to investigate the test scores of the three-tier diagnostic chemistry test (TDCT)[three-tier diagnostic tests] and multiple choice chemistry test (MCCT) by response change behaviour (RCB). The study is a descriptive research study aiming to investigate the item response efforts of TDCT[three-tier diagnostic tests] and MCCT in a…

This paper summarizes the author's experiences with transitioning from face-to-face to online General Chemistry Zoom sessions during the COVID-19 pandemic. The transition to online teaching during the COVID-19 pandemic was a Herculean task for instructors during Spring 2020. Instead of adapting completely new strategies for online teaching, the…

Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…

The two major impetuses to improve STEM education are the shift to online learning and increasing active learning and engagement. Although the COVID-19 pandemic necessitated a rapid shift to online learning, this shift came at the cost of losing on-ground active learning strategies. This study provides descriptive analytical information on the…

Spelman College, a small (~2150 students) Black women's liberal arts college located in Atlanta, Georgia, USA, is dedicated to empowering women of African descent to become global leaders and change agents. In the wake of the COVID-19 pandemic, and the resulting abrupt and unforeseen campus closure, Spelman experienced pressure and urgency to…
