Diagnosing student achievement in a formative way is a crucial skill for planning and carrying out effective mathematics lessons. This study takes a subject-specific view and aims at investigating diagnostic competence in the field of mathematical functions at secondary level and how to improve it. Following three evidence-based design principles,…

This study presents a small part of a larger study investigating Turkish and German mathematics teachers' and their students' values (Values in Mathematics Teaching in Turkey and Germany). The main focus of the study was school levels of the teachers working at primary and secondary schools. The interactions related to nationality were also of…

When entering the classroom, adolescents already hold various conceptions on science topics. Concept maps may function as useful tools to reveal such conceptions although labor-intensive analysis often prevents application in typical classroom situations. The authors aimed to provide teachers with an appropriate approach to analyze students'…

This study aims to examine to what extent the field of competence regarding curriculum knowledge is concordant with the other sub-competency fields of teaching. These fields are field knowledge, pedagogic competence in field teaching, use of information and communication technologies in teaching, student behaviours and class management,…

How teachers are able to adapt to a changing environment is essentially dependent on their beliefs and motivational orientations. The development of these aspects in the context of professional competence takes place during teachers' educational phase and professional practice. The overall understanding of professional competence for teaching…

Teachers make a difference for the outcome of their students in science classrooms. One focus in this context lies on teachers' professional knowledge. We describe this knowledge according to three domains, namely (1) content knowledge (CK), (2) pedagogical content knowledge (PCK), and (3) curricular knowledge (CuK). We hypothesise a positive…

Many studies of teacher motivation have been conducted in different contexts over time. However, until fairly recently there has not been a reliable measure available to allow comparisons across samples and settings. This has resulted in an abundance of findings which cannot be directly compared or synthesised. The FIT-Choice instrument offers the…

The years between 2005 and 2014 have been declared as a worldwide Decade of Education for Sustainable Development (DESD) by the United Nations. DESD's intended purpose is to promote and more thoroughly focus education as a crucial tool preparing young people to be responsible future citizens, so that our future generations can shape society in a…

Differences in teacher quality are commonly cited as a key determinant of the huge international student performance gaps. However, convincing evidence on this relationship is still lacking, in part because it is unclear how to measure teacher quality consistently across countries. We use unique international assessment data to investigate the…

The COACTIV video study is part of the COACTIV research program in which secondary mathematics teachers whose students participated in PISA 03/04 were examined, with respect to their professional knowledge, motivational orientations, beliefs, and self-regulation. In the video study, 284 German secondary mathematics teachers were asked to specify…

In this study, the aim is to identify the interpersonal self-efficacy beliefs of German teacher trainers' in Turkey. It is a descriptive survey and the population of the study consists of German teacher trainers who have worked in the seven regions of Turkey during the 2012-2013 academic year. The sample comprises 52 German teacher trainers chosen…

This study expands the discussion on teacher competence by investigating the relevance of teachers' combined cognitive resources and emotional resources for effective classroom management. While research on teacher qualification stresses the importance of knowledge for effective teaching, research on teacher stress focuses on their emotional…

The school as an institution assumes that students' grades are constituted by their assessments. This paper examines the background of this presupposition and provides a micro-analytical perspective of the grading practice of teachers in German High Schools ("Gymnasium"). This paper conceptualises the theoretical framework of the…

This study reported the specific findings of a larger comparative study concerning Turkish and German mathematics teachers' values. The main focus was on the teaching experience of the mathematics teachers. Interactions related to nationality were also of interest. The research methodology employed in this study was a descriptive study. The…

Teachers' content-related knowledge is a key factor influencing the learning progress of students. Different models of content-related knowledge have been proposed by educational researchers; most of them take into account three categories: content knowledge, pedagogical content knowledge, and curricular knowledge. As there is no consensus about…
