The study aimed to explore the integration of lesson study into science teacher education programs to enhance preservice science teachers' pedagogical content knowledge (PCK) for STEM. The lesson study cycle encompassed planning, teaching, reflecting, re-teaching, and re-reflecting phases, and the participants' experiences regarding PCK for STEM…

The present qualitative study aimed to investigate how school garden-based science pedagogy improves students' attitudes toward science learning, particularly in under-resourced urban school districts. The findings of this study suggest that the implementation of school garden-based science pedagogy can positively impact elementary students'…

The latest development of Generative Artificial Intelligence (GenAI), particularly ChatGPT, has drawn the attention of educational researchers and practitioners. We have witnessed many innovative uses of ChatGPT in STEM classrooms. However, studies regarding students' perceptions of ChatGPT as a virtual tutoring tool in STEM education are rare.…

In early 2022, the Human Anatomy & Physiology Society (HAPS) Curriculum & Instruction Lab Survey subcommittee launched the third survey of instructors for introductory undergraduate-level courses in human anatomy and physiology. This manuscript presents analyses of questions regarding the laboratory activities and learning outcomes (LOs)…

In South Africa, there is a strong recognition of the affordances of information and communications technology (ICT) in science teaching and learning. A key indicator for the effective use of ICT is the technological pedagogical content knowledge (TPACK) of teachers with TPACK-Practical (TPACK-P) being an important iteration related to teacher…

The mining industry in Brazil, despite contributing to economic growth, is one of the human activities that negatively impacts the environment. This situation can be contextualized in discussions of several curricular chemistry topics. One way in which science, technology, society, and environmental issues can be discussed in classes is through…

The ability to communicate scientific concepts to expert and nonexpert audiences is an essential skill for chemistry and STEM students. Current chemistry curricula mainly focus on developing skills to communicate technical information to expert audiences, while relaying the same information to general audiences receives much less attention.…

Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking.…

We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

Faculty members in STEM report numerous motivators and barriers to adopting evidence-based instructional practices (EBIPs), yet the degree to which these factors are associated with EBIP adoption in postsecondary chemistry courses is unclear. The role of departmental climate around teaching in driving or hindering EBIP adoption is particularly…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

Minoritized communities, including Black and African American, Hispanic and Indigenous populations have remained historically underrepresented in STEM careers due to persistent challenges in the STEM pipeline. The STEM pipeline has struggled to retain minoritized students in their journeys to pursue STEM degrees and careers due to systemic racism,…

Students' self-efficacy, interest, and perceived recognition from others in a given field have been shown to be very important for the development of their identity in that field, which is a critical predictor of students' major and career decisions. Prior research suggests that students' self-efficacy and interest play an important role in their…

Through this qualitative phenomenological I studied the lived experiences of online science instructors who teach online introductory science. The problem addressed in this study was the high failure and attrition rates in online introductory science courses among undergraduate students. The purpose of this study was to explore the lived…

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…
