This paper focuses on why and how treating early number bonds as scientific concepts may be the key to raising learners’ attainment in these. The paper argues that teacher mediation is crucial and that mediation for learning scientific concepts has to be meaningful, relational and transcendent. This theoretical position is illustrated with examples from a dynamic assessment interview with a Grade 2 learner carried out as part of the Wits Maths Connect —… Continue Reading →

eric.ed.gov har udgivet: Jordanian 8th grade students revealed low achievement in mathematics through four periods (1999, 2003, 2007 & 2011) of Trends in International Mathematics and Science Study (TIMSS). This study aimed to determine whether spatial visualization mediates the affect of Mathematics Learning Strategies (MLS) factors namely mathematics attitude, mathematics motivation, mathematics self-regulation, mathematics self-efficacy, and mathematics anxiety on mathematics achievement. The study consists of 360 students from public middle schools in Alkoura district, selected through stratified random sampling. It employed 65 items to assess MLS, which consists, attitude (18 items), motivation (7 items), self-regulation (25 items), self-efficacy (5 items) and math anxiety (10 items). The mathematics test comprises of 30 items, which has eight items for numbers, 14 items for algebra and eight items for geometry while spatial visualization… Continue Reading →

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: Abstract Abstract In this study, we examine whether the relationship between employees’ perceptions of human resource management (HRM) and work engagement is mediated by job crafting. Using conservation of resources (COR) theory, we propose that HR practices offer job resources which employees reinvest by displaying job crafting behaviours. Since job crafting involves the pro-active redesign of job characteristics by employees, this study advances the idea that employees are pro-active in their response to HRM and translate perceived HRM practice into attitudinal outcomes through displaying pro-active behaviour. In support of this idea, our results show that the relationship between perceived HRM and work engagement is fully mediated by the job crafting type ‘increasing job resources and challenging job demands’. The job… Continue Reading →
