Pre-service teachers (PSTs) often encounter challenges grasping the conceptual understanding of fractions, which can affect their readiness to teach this topic. This study investigates a novel approach to enhancing PSTs' comprehension of fractions by focusing on the fraction-as-a-measure meaning within a measurement context. Through a modified…

This study used structural topic models (STMs) to analyze physics pre-service teachers' conceptual understanding of scientific literacy. Participants included 126 physics pre-service teachers studying at Shandong Normal University in China. First, we used an open-ended questionnaire to collect the data. Second, STM was used to classify the data,…

Although researchers have extensively studied student conceptions of radioactivity, the conceptions held by preservice teachers on this subject are largely absent from the literature. We conducted a qualitative content analysis of problem-centered interviews with preservice teachers (N=13) to establish which conceptions are held by preservice…

The current study examined how prospective first- and second-grade mathematics teachers define the polygon diagonals concept, how they reconstruct their definition during and following an intervention, and how their concept images develop over time. Twenty-three prospective teachers participated in the study, during which they were asked to…

Some students have misconceptions. Students' misconceptions make difficult to learn the new subject. Teachers need to know students' misconceptions and take precautions. One of the misconceptions in mathematics is about limits and continuity. In order for teachers to take precautions in this regard, they must have this experience during their…

National reform documents all around the world issue an urgent need for the development of integrated STEM (Science, Technology, Engineering, and Mathematics) curricula. With the emphasis on the development of STEM curricula, there is also a need for improving teachers' and future teachers' conceptions of the integrated STEM approach. This study…

The aim of this study is to examine the concept images of mathematics educators and pre-service elementary mathematics teachers regarding the relationships between the concepts of slope, rate of change and derivative. Four mathematics educators working in different state universities and responsible for Analysis courses, three pre-service…

This paper reports on concept images of 38 secondary school mathematics prospective teachers, regarding the evenness of numbers. Written assignments, individual interviews, and lesson transcripts uncover salient, erroneous concept images of even numbers as numbers that are two times "something" (i.e., "2i" is an even number),…

Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

This experimental study examined ways to reduce stigma against children with attention-deficit/hyperactivity disorder (ADHD) symptoms. We randomly assigned 220 Chinese pre-service teachers to one of the four experimental groups in which they read a vignette describing a student with ADHD symptoms. The contents of the vignettes differed from one…

Background: The imperative for social justice in education means that pre-service teachers should learn how to teach for and about social justice, including pedagogical and content knowledge. Understanding how physical education (PE) pre-service teachers and teacher educators construct and develop their knowledge of social justice pedagogies and…

Teacher education programs need to prepare their preservice teachers to both implement current science education reforms and teach in culturally and linguistically diverse classrooms. In this qualitative study, we used a framework of four instructional principles to investigate 31 preservice secondary science teachers' understanding of instruction…

The present study aimed to remediate pre-service teachers' misconceptions about sampling distributions and to develop their conceptual understanding through the use of conceptual change texts (CCTs). The participants consisted of 84 pre-service teachers. To determine the pre-service teachers' conceptual understanding of sampling distributions, an…

Purpose: Informed by social imaginary, Canadian exceptionalism, and social inclusion, this study explores how teacher candidates experience and interpret internationalization at home at one university in Canada. Design/Approach/Methods: Data were collected from three sources--(a) policy analyses of public documents related to internationalization…

Given the vast experiences pre-service mathematics teachers (PSMTs) have with functions, one may assume that they have existing personal definitions and concept images. The purpose of this paper is to build an understanding of the variety of images that one might associate with a definition of function that includes 'for each input there is one…
