The opportunity to innovate, experiment, and take chances in the classroom should be accessible to all students regardless of the social identities they hold; however, white women and women of color (WOC) in male-dominated physics, engineering, math and computer science (PEMC) learning environments, and STEM broadly, have been expected to take…

The overarching goal of this dissertation is to examine institutional change initiatives in STEM and to understand the impact of engaging with a specific change strategy on a biochemistry educator's instructional practice. Institutional change initiatives involve executing an intentional strategy to influence teaching practices within a specific…

Governance and regulation of the use of live animals in research and teaching is examined in Australia, Malaysia, Indonesia, the Philippines, Singapore, Thailand, China, Japan and India. A comparison of the systems in different countries will enable the determination of best practice and fit-forpurpose regulation. The most comprehensive government…

Mole, molar mass and the Avogadro number are used constantly to measure the amount of substance in chemical changes. However, students have difficulty in understanding these concepts because they are not familiar with measuring very small amounts of matter that cannot be seen and weighed in daily life, like atoms. The mole concept was developed to…

As global challenges increasingly require an interdisciplinary approach, this study highlights the urgency of taking stock of the forces that guide how teachers navigate complicated concepts in their classrooms such as climate change. This study takes up science education more specifically and emphasizes that not only is it important that students…

Educational achievement disparities continue to affect subgroups based on socioeconomic status, gender, race, and ethnicity. Despite efforts to close the achievement gap, the Black-White performance gap in reading, mathematics, and science scores remains virtually unchanged. The problem is that science educators in the United States receive…

Project-based learning (PjBL) instruction is an inquiry-based method that is beneficial to student achievement and their exploration of 21st-century learning skills, but there is a gap in the literature about how Grades 6 to 8 teachers feel about PjBL and its implementation. The research problem was science teachers in the United States were not…

The M.S. Chemistry -- Chemical Education Specialization program at South Dakota State University provides in-depth general chemistry coursework to in-service high school science teachers in a virtual format. The goal of the program is for the teachers enrolled to become more effective teachers while gaining content knowledge in chemistry; in…

As schools continue to focus on outcome-based instructional practices, less emphasis is placed on the creativity and reasoning necessary for students to become effective critical thinkers. As a result, students struggle to demonstrate creative problem-solving skills in the classroom. This study examines how the facilitation of an instructional…

Two-tiered assessment structures with paired content and confidence items are frequently used within chemistry assessments to stimulate and measure students' metacognition. The confidence judgment is designed to promote students' reflection on their application of content knowledge and can be characterized as calibrated or miscalibrated based on…

This study explored whether, and how, preservice elementary teachers' scientific curiosity related to their confidence for science teaching. A group of 29 preservice, elementary teachers in the U.S. engaged in a curiosity journaling strategy across a 16-week scientific inquiry course. Their expressions of curiosity were coded using Luce and Hsi's…

Integrating computational thinking (CT) into STEM disciplines requires secondary teachers to develop their pedagogical content knowledge of computing and content integration. Experienced teachers who choose to integrate CT in their secondary STEM courses may struggle in the same ways as novice teachers as they learn about programming and its…

Second-term general chemistry is a key gateway course at our institution for a variety of STEM (Science, Technology, Engineering, and Mathematics) majors. Herein, we examine data on DFW% (i.e., % of D and F grades and withdrawals) in our general chemistry courses over roughly a quarter-century period, focusing on sections taught by the authors.…

This article describes the design and implementation of a sensors-based entrepreneurial-minded learning (EML) module in a large (>150 students) first-year General Chemistry II course. Students worked in groups create a novel sensor that solves an existing scientific problem or improves upon an existing sensor. Students proposed and explained…

Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…
