Teacher noticing, a situation-specific part of teachers' professional competence, has gained much importance in the past two decades. The construct is believed to play a crucial role in the transfer of knowledge and skills into professional teaching performance. However, there is little empirical evidence on how the length of teachers' teaching…

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 intervention programmes have a direct influence on teachers' knowledge of teaching different topics. This paper focuses on how Grade 8 natural science teachers' knowledge developed during an intervention programme. Eight schools were selected to participate, and 25 Grade 8 Natural Sciences teachers from Gauteng province participated. Data were…

Teachers' job satisfaction and teacher self-efficacy in teaching are two of the main factors driving STEM teacher shortages in teaching students who are English Learners (ELs). This study investigated the impact of teachers' perceptions of school climate and professional development (PD) participation on teacher self-efficacy in teaching and job…

Teacher scaffolding is crucial to promote students' cooperative learning processes, but little is known about the cognitive attention underlying teachers' scaffolding behavior. This study aims to investigate the scaffolding behavior teachers exhibit while intervening in students' cooperative learning and to explore the relation between teachers'…

The most famous equation in physics, E = mc[superscript 2], is rarely introduced in middle school physics curricula. Recent research has shown that teaching Einsteinian concepts at the middle school level is feasible and beneficial. This paper analyses an Einsteinian energy teaching module for Year 8 students (13-14 years old), which encompasses…

There are conflicting reports not only on the effect of scientific inquiry on academic achievement but also insufficient evidence on the relationship between understanding the nature of scientific inquiry and academic achievement; more generalizable studies are needed. The purpose of this large sampled study was to investigate the middle school…

This study is aimed to understand the connections between didacticians' meta-didactical praxeologies for the design and implementation of a teacher professional development program and their documentation work for the program itself. Didacticians are mathematics education researchers with the role of teacher educators. Data presents a case study,…

While scholars have proposed incorporating the study of complex phenomena such as chaotic systems in high school and undergraduate-level curricula, the literature on this topic is scant and has focused mostly on the analysis of mathematical models--and often only on certain populations, such as gifted students. We report in this manuscript an…

This study aimed to design a task in an everyday context to support high school students' exploration of the truth values of propositional conditionals and to understand their difficulties. The results showed that students could identify that the truth value of a propositional conditional is determined by two variables (the truth values of the…

Teachers lack effective curriculum-based instruments to assess their students' scientific competence that would provide information for modifying their inquiry instruction. The main purpose of this study was to develop and validate a Curriculum-Based Scientific Competence (CBSC) test to assess students' scientific competence in a 1-semester Grade…

When justifying a mathematical statement, textbooks often interweave several instances of justification, creating, what we term, "paths of justification." This study aims to characterize the paths of justification of mathematical statements that are offered in eight 7th grade Israeli mathematics textbooks. The study attended to context…

Instructional quality dimensions of cognitive demands and instructional support have been shown to have an impact on students' learning gains. Existing operationalizations of these dimensions have mostly used comprehensive ratings that combine various subdimensions of task quality and interaction quality. The current study disentangles interaction…

In recent decades, research has stressed the prominence of mathematics classroom discussions in productive instructional practices in mathematics instruction. In this context, problem-solving activities have been a common focus of research. Research shows that teachers need to deal with prerequisites and challenges such as norms, design of tasks,…

Problem-solving is, by nature, a creative process which, by teaching through the implementation of research and discovery activities, allows students to create their knowledge, revise it and link it to broader systems. The aim of the research was to describe and analyse the process of solving biological problems through activities that are…
