The importance of constructing mathematical arguments and critiquing the reasoning of others has been emphasized as a key component for deep mathematical understanding. As a result, acknowledging proof as an essential tool to comprehend mathematics at all grade levels has been suggested by many researchers as well as reform initiatives. To do so,…

This study aims to reveal how model eliciting principles are used in the process of designing, applying, and evaluating teacher candidates' model-eliciting activities. This study was conducted in three stages in a multi-tiered teaching experiment. Firstly, 15 teacher candidates designed activities for Grade 7 students after they were trained on…

This study aimed to elicit middle school preservice mathematics teachers' self-reported web of knowledge recalled in generating mathematically rich and contextually realistic problems. We designed this study as multi-tier design research incorporated into two teacher education courses in which 40 preservice teachers enrolled in total. Preservice…

In this study, we report the results of the content analysis of preservice middle school science teachers' own written science storybooks and middle school female students' reflections of five of the books. The participants of this study were 50 preservice middle school science teachers taking a history and nature of science course and 13…

This study investigated how pre-service middle school mathematics teachers attend, interpret, and respond to the students' thinking about statistical concepts in a case-based teacher training environment. 25 pre-service middle school mathematics teachers participated in the study, and they were asked to make evaluations on the cases given. Based…

The purpose of this study was to compare the concept images and hierarchical classification skills of students at different educational levels (middle school, high school, and university) regarding parallelograms. In this study, a cross-sectional research design was utilized. The study group consisted of a total of 357 students from middle school…

This research examined how pre-service mathematics teachers (PMTs) plan to support argumentation in their lessons about the hierarchical relationships among the quadrilaterals and what they notice during planning. The participants of this case study were eight pre-service middle-school mathematics teachers. Data consisted of the PMTs'…

It was aimed to examine pre-service teachers' developing understandings of doing statistics within a lesson study. It was focused on their understandings (i.e., content knowledge) of doing statistics as well as how they transform their understandings (i.e., content knowledge) into teaching practices (i.e., knowledge of student & knowledge of…

Questioning is a core practice used comprehensively in many areas of teaching mathematics. It is an important part of the teacher's ability to establish a classroom atmosphere conducive to the development of mathematical thinking. The study aimed to investigate the types of questions used by pre-service middle school mathematics teachers (PSMTs)…

Preservice middle school mathematics teachers' (PMTs) beliefs about a mathematics teacher and mathematics teaching were investigated through the metaphors they generated. Third- and fourth-year PMTs (N = 249) at four universities in Türkiye participated in two anonymous metaphor tasks for a mathematics teacher and mathematics teaching. PMTs'…

The aim of this study was to determine the correlation between self-, peer- and teacher- assessment to evaluate preservice science teachers' classroom teaching activities. A mixed method was employed. The sample consisted of 55 senior students (29 women, 26 men) from the science teaching program of a public university in Turkey. Quantitative data…

In studies over recent years, there has been an increasing interest in teachers' predicting middle school students' thinking processes. However, as far as we are aware, there are no studies examining students' thinking in terms of mathematical thinking components. This study primarily aimed to determine the mathematical thinking of middle school…

Research on Mobile Augmented Reality (Mobile AR) includes studies addressing Mobile AR integration into learning environments along with the quality of instructions by researchers about using mobile AR in classrooms. Findings revealed that even inexperienced teachers/pre-service science teachers who lacked any prescribed material could use mobile…

The main purpose of this study is to identify alternative concepts that students possess on the colour of blood and determine the strength of those concepts as well as the reasons for why students constructed them. The sample of the study consisted of participants who were selected from three different cohorts of students (i.e. middle-school,…

This study was conducted to examine the effectiveness of proof tasks in the transition from conjecture to proof in Euclidean geometry on freshmen's proof schemes. In line with this aim, the proof schemes of the freshmen who performed conjecture-proof and theorem-proof tasks were compared. The freshmen were composed of 109 pre-service middle school…
