Problem solving is considered an essential ability for becoming an expert in physics, and individualized feedback on the structure of problem-solving processes is a key component to support students in developing this ability. Problem-solving processes consist of multiple elements whose order forms the sequential structure of these processes.…

Teaching assistants have a very important role in physics education as they interact with students and guide them in different contexts. A multitude of research has focused on how to prepare teaching assistants to implement high-quality, research-based teaching techniques. Video clubs, i.e., working with a group of teachers to watch and discuss…

Undergraduate laboratory courses can provide opportunities for students to participate in science practices. This requires rethinking both curricula and instruction. Science practice--based courses require students to be positioned as epistemic agents, implying a shift in instructor role. Teaching assistants (TAs) are the primary instructors for…

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…

Fostering students' scientific literacy is a key goal of science education, with understanding the nature of scientific inquiry (NOSI) as a central component. Achieving this goal requires teachers to possess adequate knowledge in this area. However, assessments indicate that pre-service science teachers (PSTs) have not yet developed comprehensive…

Science learning requires students to build new mental models of imperceptible mechanisms (photosynthesis, circadian rhythms, atmospheric pressure, etc.). Since mechanisms are structurally complex and dynamic, building such mental models requires mentally simulating novel structures, their state changes, and higher-order transformations…

Despite the increasing number of coding initiatives to promote computational thinking (CT), their main focus on in-service teachers in large school districts of the big cities far from exemplifies opportunities for preservice teachers (PSTs) to learn how to promote it in rural elementary school settings. As a preliminary step, this research…

Even though the "Next Generation Science Standards" (NGSS) were released over a decade ago, science is still infrequently taught in early childhood and elementary classrooms. A lack of teacher confidence due to inadequate content knowledge may be a contributing factor, making access to high-quality elementary science methods courses even…

Estimating astronomical scales requires multiple complex mental processes, such as spatial thinking and interpreting large numbers. As such, it is a nontrivial question how these estimates can be most efficiently assessed. There is reason to believe that results from previous studies probing astronomical scale estimates are possibly susceptible to…

In this paper, we propose a novel method for deriving Russell-Saunders terms of complex atomic systems with an arbitrary number of equivalent electrons in orbitals with a higher azimuthal number. The method can be regarded as an extension of the classic works of Douglas, McDaniel, and Hyde but with several notable improvements, including the…

The educational benefit of the traditional didactic lecture to learners in Higher Education is hotly debated. Given increasing student numbers, existing technical set ups and many logistical concerns, lectures remain the norm in many Higher Education Institutions (HEIs). In this personal view piece, we discuss the benefits, opportunities, and…

This study examined the impact of action research conducted by five science teaching methods course instructors on their students' perceptions of the classroom learning environments at a large public university in Texas. The study analyzed the results from 133 students who completed two administrations of the What is Happening in this Class…

The purpose of this study was to explore an approach to an elementary science methods course that utilized a science notebook to physically distinguished multiple perspectives of science teaching and learning. We conceptualized teacher candidates' (TCs') thinking within a framework titled "Exploring Multiple Perspectives in the Methods…

Biochemistry is becoming increasingly crucial for undergraduates majoring in biology, chemistry, agriculture, and medicine. In recent years, much research has been carried out on promoting this course's teaching outcomes. However, the knowledge structure of undergraduate biochemistry teaching research has yet to be formed. Here, 715 validated…

Pedagogical content knowledge (PCK) is important for teachers' instructional effectiveness. This study investigated the self-reported level of PCK among in-service elementary school science teachers in a municipality in Ghana, examining the overall level of PCK. An In-Service Elementary Science Teachers Self-Reported PCK (IEST-SR-PCK) scale was…
