We examined the structure of domain-specific academic science vocabulary, general academic vocabulary, and conceptual science knowledge and their impact on each other across two measurement points in a sample of 388 German third graders. Results show that the three constructs can be empirically differentiated. The high latent correlation between…

Measurement estimation skills are relevant for our everyday life and should be addressed in the mathematics classroom. Although students' measurement estimation skills were examined in several empirical studies, a structure model to describe these skills is still missing. The current research aimed at analyzing the structure of length estimation…

Although children with specific reading disorder (RD) have often been compared to typically achieving children on various phonological processing tasks, to our knowledge no study so far has examined whether the structure of phonological processing applies to both groups of children alike. According to Wagner and Torgesen (1987), phonological…

This study is a substantive-methodological synergy in which exploratory structural equation modeling is applied to investigate the factor structure of multidimensional self-concept instruments. On the basis of a sample of German students (N = 1958) who completed the Self-Description Questionnaire I and the Self-Perception Profile for Children, the…

This paper aims to research practices of resistance as an important part of agency in primary school classrooms. By combining a post-structural theoretical frame with a critical ethnographic research approach, it understands children's resistance as an ordinary practice, as a necessary response to structures and practices of the classroom setting.…

Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…

This study aims to develop a short German version of the Self Description Questionnaire (SDQ I-GS) in order to present a robust economical instrument for measuring German preadolescents' multidimensional self-concept. A full German version of the SDQ I (SDQ I-G) that maintained the original structure and thus length of the English original SDQ I…

The paper reports a cross-cultural investigation conducted in 2001-2002 that seeks to reveal students' alternative ideas in two countries, Taiwan and Germany. It was carried out by means of semi-structured interviews in a story form. The targeted students were arbitrarily selected from grades 3 to 6 in both countries and amounted to 64. The…
