As a result of the worldwide dissemination of COVID-19, educational institutions across the globe, particularly those that serve students in the field of science, have been mandated to close their doors. Consequently, educators and students have increasingly relied on educational technology to obtain a diverse array of resources. This research…

Science teaching efficacy belief (STEB) is of paramount importance as it motivates teachers to teach science or hinders them from teaching science. Preservice teachers' efficacy beliefs may change during their method courses. Knowing how pre-service teachers' beliefs change over time can significantly contribute to teacher educators to improve…

This study was carried out in order to investigate the impact of implementing video-based predict-observe-explain (POE) on students' scientific literacy, particularly in chemistry's concept of salts. The hypothesis of this study was that students' scientific literacy would improve after implementing video-based POE within teaching, in the context…

Conceptual knowledge is a crucial tool for students to understand scientific phenomena. Knowledge about the structure and function of mental concepts potentially helps science educators to foster the acquisition of this tool. Specifically, the coherence of students' mental concepts is an intensely discussed issue within the related conceptual…

Students must actively engage in problem solving to effectively learn in introductory physics courses. However, students often get stuck and are not able to make progress when solving problems outside of their current ability, particularly when one-on-one tutoring and instructor office hours are a limited resource. One effective technique consists…

This study, based on the theory of Technological Pedagogical Content Knowledge investigated the effectiveness of introducing open source YouTube videos in the teaching and learning of the Chemistry topic 'Group Properties' at a high school in Lesotho. A quasi-experimental design was used for two conveniently selected Form D classes; one class used…

Science includes a multitude of specialized terms that are not consistently taught using effective practices. Often, students with disabilities rely on ineffective strategies in order to memorize word definitions, which inhibits their science achievement. Using a counter-balanced design, we tested whether having access to multimedia videos that…

This research aims at comparing the changes in factual, conceptual, and procedural knowledge of heat transfer in learning science using YouTube videos accompanied by discovery learning among fifth graders. A pre-and post-test experimental design was conducted by two different groups. One of the groups was randomly assigned to conduct discovery…

Two volunteer BEd student teachers in their fourth year of a BEd degree at a metropolitan university in the Western Cape of South Africa designed and taught lessons to two classes of the same age and ability in grade 7 (ages 12-13), using drama role-plays (intervention) and more conventional non-drama methods (control). Lessons were observed and…

Although development of critical thinking skills has emerged as an important issue in undergraduate education, implementation of pedagogies targeting these skills across different science, technology, engineering, and mathematics disciplines has proved challenging. Our goal was to assess the impact of targeted interventions in (1) an introductory…

Argumentative practices have the potential to contribute to scientific literacy. However, these practices are not widely incorporated in science classrooms and so their effect on the domains of literacy is still not revealed. Therefore, this study proposes to reveal the effect of argumentation on the three domains of chemical literacy related to…

E-textbooks are more prevalent in college courses, but much recent research still shows that students prefer paper textbooks and have difficulty regulating their learning with digital course materials. Still, college instructors--especially in lower-division STEM courses--often adopt digital course materials with e-textbooks that include a variety…

The flipped classroom continues to attract significant attention in higher education. Building upon our recent parallel controlled study of the flipped classroom in a second-term general chemistry course ("J. Chem. Educ.," 2016, 93, 13-23), here we report on a redesign of the flipped course aimed at scaling up total enrollment while…

The purpose of this study is to develop personalized web assisted activities for the flipped classroom model applied in the "Human and Environment Interactions" unit of science lesson and to research its effect on students' achievement. The study was conducted with the 74 participation of 7th grade science lesson students within a period…

Experts are more proficient in manipulating and translating between multiple representations (MRs) of a given concept than novices. Studies have shown that instruction using MR can increase student understanding of MR, and one model for MR instruction in chemistry is the chemistry triplet proposed by Johnstone. Concreteness fading theory suggests…
