Reformed science curricula provide opportunities for students to engage with authentic science practices. However, teacher implementation of such curricula requires teachers to consider their role in the classroom, including realigning instructional decisions with the epistemic aims of science. Guiding newcomers in science can take place in…

We developed a single crystal X-ray crystallography experiment based on the crystal structure of sucrose (table sugar), and a more challenging experiment using Epsom salt. Both crystals are readily available in X-ray quality crystalline form. In these experiments, students mounted a crystal on a MiTeGen loop and analyzed it using a Rigaku XtaLAB…

General chemistry courses serve as foundational curriculum within most STEM undergraduate curricula, and hence, it is essential to assess student knowledge and application of learning outcomes for courses such as Introduction to Chemistry and Organic Chemistry. Within the United States, paper-and-pencil examinations are typical for measuring…

In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

In response to the global crisis of type 2 diabetes prevalence, this dissertation investigated the impact of a culturally sustaining, health-centric science curriculum contextualized in type 2 diabetes. Using a case study methodology, it explored how the curriculum shaped math and science preservice teachers' (PSTs) perceptions of science and how…

Collaborative learning methods are increasing in popularity as a way of improving student performance and involvement in undergraduate courses. For this study, a group quiz format was used in an attempt to improve course grades and engagement in an introductory meat science course. Six group quizzes and six individual quizzes were taken by 70…

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…

The purpose of the study is to investigate how pre-service elementary teachers' orientation about science inquiry impacts their implementation of inquiry-based instruction. Teaching orientation is one of the levels of pedagogical content knowledge (PCK) which impacts on teachers' instructional practice. With thirty-one pre-service teachers, data…

The rise of global environmental issues has stressed the importance of sustainability and green chemistry teachings. Nevertheless, these topics remain largely untouched in most post-secondary organic chemistry lecture courses. This article investigates the barriers to integrating green and sustainable chemistry into organic chemistry classrooms…

In this study, an innovative scientific modeling course on concentration cells is designed: First, the demonstrations revealed examples of three different concentration cells. Then, scientific models visualizing the process and principle of cell reactions at the level of microparticulates were introduced to students. Finally, three new…

Introduction: The aim of the study was to examine the effects on Primary School Teacher Candidates of developing and implementing jigsaw technique activities enriched with educational games in Science and Technology Teaching lessons. Methods: In the study, the mixed design was used. The single group pre-test post-test weak experimental pattern…

We share a case study on our use of three reflective questions to demonstrate ways in which simple questions can be coded to reveal rich evidence of impact and engagement. At the end of a three-hour inclusive teaching practices workshop for 23 faculty and administrators from a single science department, 22 participants completed an anonymous…

A six-laboratory session biofilm-focused biochemistry laboratory module is described. Through just six four-hour laboratory sessions over three weeks, students first master background knowledge and fundamental experimental techniques to explore questions involving bacterial biofilms at the interface of microbiology and biochemistry and then…

The STEM education has been emphasized in many countries around the world because of its benefits for students in the new century. In response to the STEM education, Next Generation Science Standard (NGSS) has released a new vision of science education in which learning disciplinary content and crosscutting concepts is to engage science and…

Outdoor field experiences have long been part of the traditional curriculum in geoscience-related disciplines and are considered a key aspect of professional development in these areas. When the COVID-19 pandemic forced the cancelation of many field excursions around the world, geoscience departments were forced to make abrupt changes to the ways…
