We designed and evaluated a student laboratory workshop on plant-based vaccines against the SARS-CoV-2 virus. The workshop focused on hands-on laboratory techniques, including DNA extraction from rice seeds, where the recombinant protein was produced, detection of the transgene, and basic concepts on how vaccines work in the human body to offer…

This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

Teaching quantum physics (QP) to high school (HS) students is gaining momentum, necessitating the exploration of various effective methods. Specifically, the research on quantitative teaching methods is still in its early stages. Understanding the power of Dirac notation (DN) in teaching is crucial for grasping the complexities of QP, as it…

Cambodian upper secondary education is divided into two tracks: science and social science. Students make their track selection in grade 10 and begin their enrollment in grade 11. The enrollment in the science track has witnessed a steep decline from 96% in 2014 to 34% in 2020, while the enrollment in the social science track has seen a remarkable…

STEM education has experienced significant growth due to its pivotal role in innovation and economic development. While cognitive factors like prior knowledge are known predictors of STEM success, non-cognitive factors, including attitudes and demographics, also play vital roles. However, there is a notable scarcity of research focusing on the…

The ability to do inquiry does not necessarily translate to understandings about scientific inquiry or the processes by which scientific knowledge is generated. The study reported in this paper focuses on what students know about scientific inquiry and what impact school science may have on this knowledge. We investigated grade 12 physical and…

The study investigates secondary students' understanding of "orbital" and "electron cloud" concepts in different quantum contexts (for values of the ?principal quantum number n = 1 and n = 2) on the basis of their verbal and pictorial representations, evaluating also their consistency. Participants, which were 192 12th-grade…

Unstructured out-of-school time (OST) science activities, such as reading a science book, watching a science television show, or researching on the internet about science, constitute a self-sustaining way for adolescents to engage in science, technology, engineering, and mathematics (STEM). Although it is suggested that long-term engagement in…

This study focuses on examining the mental models of 11th and 12th-grade students attending a science high school in Turkey regarding the concept of the electron cloud. The study involved 72 students and employed the case study method. The precondition for selecting the sample was that the students had covered the unit on modern atomic theory in…

The visibility of female role models in science is vital for engaging and retaining women in scientific fields. In this study, we analyse four senior secondary science courses delivered across the states and territories in Australia: Biology, Chemistry, Environmental Science, and Physics. We compared male and female representation within the…

The decline of females in Science, Technology, Engineering, and Mathematics (STEM) fields has drawn global discourse among researchers and policymakers, including Cambodia. At Cambodian upper secondary schools, female students' enrolment rates in science classes dramatically decreased from 97% in 2014--42% in 2019. In contrast, female students'…

South African teachers experience challenges with the implementation of the national school curriculum -- the "Curriculum and Assessment Policy Statement" (CAPS). In this regard, teachers may not feel empowered to effectively deal with the demands of the current educational policy. Concerns have been expressed about learners' poor…

Textbooks can have a fundamental and positive effect on both learning and teaching. As such, in order to understand how students structure concepts in their minds, it is necessary to analyze the structure in which those concepts presented in textbooks are described. This study examined a network of concepts used in the domain of biotechnology in…

Environmental stewardship education, as a locally oriented concept, benefits from being recast to account for the emergent, multidimensional, and interdisciplinary nature of today's most pressing socio-ecological issues. In an effort to infuse environmental stewardship education with global citizenship, instructional materials on community-based…

This research aimed to: a) synthesize the Science, Technology, and Society Phenomenon-based Learning Model (STS-PhBL) for teaching Geoharzard to students; and b) compare students' problem-solving skills prior to and after the STS-PhBL lessons on the Geoharzard topic. The sample consisted of 39 Grade 12 students enrolled in the first semester of…
