Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

Sensemaking has been advocated as a core practice of science education to support students in constructing their own understanding through a prolonged trajectory. However, the field lacks a discussion of teaching strategies that can better support students as they develop in the trajectory of sensemaking, which includes four phases: initial…

This article introduces and contextualizes the content of this theme issue of "The American Biology Teacher" (ABT), which focuses on integrating elements of the history of science (HOS) in biology instruction. Such orientations can enhance students' understanding of core biological concepts and the process of scientific discovery by…

Diffraction is an important phenomenon in physics. This paper describes using a scanning electron microscope (SEM) to produce cross-sectional images of iridescent seashells. When seashell cross-sections are viewed in a SEM, regular structure is seen. Seashells are a good example of a biocomposite material and good natural objects for introducing…

This multiple case study focused on the implementation of a computer-aided design (CAD) simulation to help students engage in engineering design to learn science concepts. Our findings describe three case studies that adopted the same learning design and adapted it to three different populations, settings, and classroom contexts: at the…

This study aims to conduct a detailed investigation on the effect the use of concept mapping, as an individual learning tool, has on students' success in learning the concept of gravimetric analysis. This study applies a case study research design to quantitatively examine the effect of the use of concept mapping and to conduct a detailed…

Assessing student learning to adapt instruction to support learning is an important skill all teachers need to develop. However, it is not an easy task for teachers and even more difficult for new teachers. The current study aims to explore an alternatively certified new chemistry teacher?s understanding and practices of classroom assessment to…

Multicultural education invites teachers to support students in critiquing the foundations of a given discipline, with the aim of reimagining that discipline and the purposes it serves. In this paper, we present a series of cases in which high school physics teachers who are enrolled in a summer professional development course expressed vexation…

Science fiction (SF) combines realistic and imaginary elements of science and technology and develops students' imagination, creativity, and interest in science. Therefore, the aim of this study is to examine SF stories written by pre-service science teachers (PSTs) in terms of various textual and science variables. The case study of SF story…

Since pedagogical content knowledge (PCK) influences the teaching learning process, it has dominated research on teacher effectiveness. This case study explored teachers' enacted topic-specific PCK (TSPCK) during the biology lesson study stages: planning, teaching, and reflecting. The enacted TSPCK in two video-recorded research lessons was…

Massive pretrained language models have garnered attention and controversy due to their ability to generate humanlike responses: Attention due to their frequent indistinguishability from human-generated phraseology and narratives and controversy due to the fact that their convincingly presented arguments and facts are frequently simply false. Just…

In this study, we explored undergraduate chemistry education at Kotebe University of Education (KUE) in terms of the ontological orientations, patterns and source domains of educators' and undergraduate students' sense of the atom. Due to the ambiguity and controversy regarding atomic ontology as a case of interest and the requirement for a…

Literature shows that science teachers' development and practice of PCK have always been a concern in science education research. Globally, national policies have begun to underscore the instruction of science teachers as a great concern. This study is considered worthwhile, as it intended to address this gap by exploring a beginner teacher's PCK…

Teachers' responses to student contributions in science classroom influence the resulting classroom interaction. To establish a heightened interaction, teachers need to use specific discursive moves. Using the notion of noticing as a lens, in this qualitative case study, I report on how the notion of noticing and responding with a suitable…

There is growing interest in implementing reform-based lab courses in undergraduate physics that are student driven rather than instructor driven. In these courses, students develop and carry out experiments while simultaneously reasoning about their hypotheses, data collection procedures, collected evidence, and the relevant physics content.…
