Virtual instruction at the K-12 level is on the rise, yet we know very little about the ways students engage in different types of virtual instruction. The goals of this study were to: (1) describe high school students' engagement in virtual science courses in terms of behavioral, affective, cognitive-value, and cognitive-self regulatory…

Science museums conduct presentations for their audiences to attract and educate visitors, yet research on presentations has primarily concentrated on whether individual presentations were effective. This mixed-methods, quasi-experimental study looks at how the presenter's mental and physical engagements within a presentation affects audience…

Evolution is one of the most important concepts in biology, but it is rejected by a substantial percentage of religious students due to a perceived conflict with their religious beliefs. The use of religious cultural competence in evolution education (ReCCEE) has been shown to effectively increase evolution acceptance among religious students…

Integrated STEAM education (science, technology, engineering, art, and mathematics) has been shown to effectively foster global competencies as well as school and societal engagement for 21st century learners of diverse backgrounds. However, facilitating quality STEAM teaching and learning can be challenging for teachers, particularly in the area…

This qualitative study compares four public school districts in a state to investigate how "Next Generation Science Standards"-aligned, three-dimensional science classroom teaching and learning in biology classrooms could become normal, instead of exceptional. Interview data were collected through two rounds of interviews -- one year…

Engagement in active learning and learning communities is important for persistence of STEM students early in their academic programs. Colleges and universities have an ongoing call to facilitate active learning techniques, yet large group, lecture-based instruction is still the prominent method of instruction. This qualitative case study examines…

Reformed Experimental Activities (REActivities) is an innovative approach to the delivery of the traditional material in an undergraduate organic chemistry laboratory. To better understand the fidelity of implementing this pedagogy and what effects the framework of REActivities has on student-instructor interactions, an observational protocol…

The quest in the "Mirror Mirror on the Wall, Which Chiral Drug Is the Fairest of Them All?" escape room activity was to find an enantiomer drug that cures a "sleeping sickness". Based loosely on the story of Snow White, first-year pharmacy student pairs had 50 min to solve gamified stereochemistry quizzes (tasks 1-4), collect…

Chemistry is often seen as an abstract and content-heavy subject. Many students struggle with chemistry because they attempt to memorize the content without understanding the concepts. As a result, students often have misconceptions. COVID-19 has driven teaching and learning online, and an escape room teaching method, which is a way to enhance…

For the past five years, all Moroccan universities suspended practical work activities in the subject of chemistry for the first year due to a decision made by the Ministry of Higher Education. This study explores the effect of using a Microcomputer-Based Laboratory (MBL) on students' performance and investigates the desirability to convert…

Polymer chemistry is an important subject in the undergraduate chemistry curriculum. It is required for ACS-certified degrees and significantly connects to real world issues like the plastic waste crisis. While some concepts of polymer chemistry can be incorporated into lecture courses, students' understanding of material properties and…

Three direct complexometric titration methods for bismuth subsalicylate determination in over-the-counter stomach relief caplets and liquids are presented, as well as a UV-vis assay, for use in student laboratories. The main difference between titration methods is the choice of indicator; either xylenol orange (XO), pyrocatechol violet (PV), or…

Science reform efforts over the years have addressed the need to make science engaging and accessible for all learners. These efforts attend to multiple aspects of science teaching and learning, including, but not limited to, more intentional focus on teaching students about the nature of science, as well as increased use of Culturally Relevant…

The electromotive force (EMF) is the work per unit charge around a wire loop caused by a time-varying magnetic flux threading the loop. It is due to a force moving the charges around the loop. This is true whether the change in flux is due to the wire loop being stationary and the field changing in time, or the loop moving through a spatially…

The debate over the mechanisms responsible for the flow rates of simple tube siphons has received much attention in the physics education and general physics literature in the past decade. Particularly with regard to the driving mechanism for water siphons, some suggested explanations emphasize contributions, or lack thereof, from the atmospheric…
