This study investigated preservice secondary mathematics teachers' difficulties with and understanding of graphs of two-variable inequalities with the lens of the APOS theory. The analysis showed that most teachers understood inequality graphs as actions, at best, and used informal rules to construct graphs. They also had difficulty justifying…

The present study aimed to evaluate the use of metaphors by preservice science teachers on the subject of genetically modified organisms (GMOs). In the study, a phenomenology method was employed in the scope of a qualitative research model. The study group was composed of 189 preservice teachers who were employed in various science fields (e.g.,…

Introduction: Although there is ambiguity about the elements of teacher knowledge, all researchers accept that being able to anticipate what errors can be made, the reasons for and the strategies to overcome these errors, in short, the knowledge of students is important for student achievement. In this study, knowledge of students refers to being…

This study explores Bhutanese in-service science teachers' conceptions of the nature of science (NOS) by using the Understanding Nature of Science (UNOS) questionnaire. The 15, two-tiered items focus on the five aspects of NOS: (1) scientific knowledge; (2) scientific theories and laws; (3) scientific method; (4) scientists' work; and (5)…

It has recently been suggested that pedagogical content knowledge (PCK) has a concept-specific nature, beyond the topic-specific level of PCK. This paper reports a case study of three pre-service teachers' reported PCK about three fundamental concepts within the topic of electrostatics, namely electrostatic force, electric field and electric field…

This study is a qualitative investigation of faculty members' perceptions of their preparedness to teach the growing number of students with learning disabilities (LDs) within the community college setting. As part of a larger mixed-methods study, we conducted semistructured interviews with 12 college faculty and used thematic analysis to identify…

Non-autistic adults often hold explicit and implicit biases toward autism that contribute to personal and professional challenges for autistic people. Although previous research indicates that non-autistic adults with higher autism knowledge and familiarity express more inclusionary attitudes, it remains unclear whether training programs designed…

This research aimed to assess the influence of the method of conceptual change on understanding the concept of increasing the mass of plants among 414 students in agricultural education in Slovenia. In photosynthesis, biomass is produced, so understanding these processes is essential for successful agriculture. Data were collected using a…

An understanding of biological variation is important for understanding ecological interactions, ecosystem function, and species' response to environmental change. Biological variation is essential to species survival because natural selection acts upon the phenotypic variation within a population: the more varied the population's genetic…

The present study elaborates on a domain-specific approach to NOS (Nature Of Science) and employs a NOTSs (Nature Of The Sciences) agenda to investigate how Greek in-service physics teachers understand the unique features of school physics and biology. Our theoretical framework focuses on the notion of worldview and important differences that…

This study aims to assess learning outcomes and identify students' misconceptions in plant classification. We conducted a questionnaire survey with undergraduate and master's students. The qualitative analysis of the students' responses made it possible to shed light on the difficulties of assimilation of many notions and also to identify the…

Background: Conceptual change is a process in which an individual's understanding and the basis of this understanding change over time. Vosniadou's framework theory explains conceptual change in terms of how students learn to relate the observable and unobservable in everyday phenomena. As a result, courses that relate physical phenomena to…

The purpose of this study is to examine the process of conceptual change in which the heat concept has gone through in time and provide an analytical assessment. To this end, problem-based learning groups were formed with 13 sophomore university students. One of these students was selected and interviewed. The interviews were examined using the…

In this paper, undergraduate student attitudes towards rapidly shifting to an entirely online learning environment were assessed due to COVID-19. In addition, surveys on perceptions about misinformation in media, overall anxiety towards distance learning, knowledge of disease outbreak, and level of preparedness during the onset of the Coronavirus…

This national study of 1858 teachers participating in professional development(PD) summer programs in the United States encompasses a wide range of science subjects and grades. It was conducted to identify program features associated with increases in two types of teacher knowledge that are goals for most professional development programs: teacher…
