tandfonline.com – Factors influencing students’ proficiency development in the fraction domain: the role of teacher cognitions and behaviour

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Abstract In this study, we investigated which teacher characteristics influence student proficiency development regarding fractions in Grade 5 of Dutch primary education. At least three domains of research (i.e. perspectives) on effective teaching can be distinguished: studies focusing on teachers’ background characteristics, on their knowledge and conceptions regarding the subject they are teaching and on the domain-specific and general pedagogical characteristics of their teaching. In this study, effects of the three perspectives on student fraction proficiency were examined simultaneously using multilevel analyses. Findings revealed that teachers’ age and experience in the upper grades, their pedagogical content knowledge and the degree of student participation in their lessons had positive effects. Their subject matter knowledge, quality of their concept maps and… Continue Reading

Abstract Ontologies play an important role as knowledge domain representations in technology-enhanced learning and instruction. Represented in form of concept maps they are commonly used as teaching and learning material and have the potential to enhance positive educational outcomes. To ensure the effective use of an ontology representing a knowledge domain it needs to be validated. In this paper a previously presented validation methodology for concept maps is exemplified. Two different types of concept map validity are distinguished, referring… Continue Reading
