A Psychometric Framework for the Evaluation of Instructional Sensitivity

Although there is a common understanding of instructional sensitivity, it lacks a common operationalization. Various approaches have been proposed, some focusing on item responses, others on test scores. As approaches often do not produce consistent results, previous research has created the impression that approaches to instructional sensitivity are noticeably fragmented. To counter this impression, we present an item response theory–based framework that can help us to understand similarities and differences between existing approaches. Using empirical data for illustration, this article identifies three perspectives on instructional sensitivity: One perspective views instructional sensitivity as the capacity to detect differences in students' stages of learning across points of time. A second perspective treats instructional sensitivity as the capacity to detect differences between groups that have received different instruction. For a third perspective, the previous two are combined to consider differences between both time points and groups. We discuss linking sensitivity indices to measures of instruction.     

Working memory capacity and reading skill moderate the effectiveness of strategy training in learning from hypertext

Cognitive and metacognitive strategies are particularly important for learning with hypertext. The effectiveness of strategy training, however, depends on available working memory resources. Thus, especially learners high on working memory capacity can profit from strategy training, while learners low on working memory capacity might easily be overtaxed. In addition, efficient basic reading comprehension processes are important for strategy training to be successful: When both the newly acquired strategies and poorly routinized basic reading comprehension processes compete for working memory resources, navigation within the hypertext and learning might deteriorate rather than improve. In an experiment, 64 undergraduates learned with a comprehensive expository hypertext after receiving either a cognitive or a metacognitive or no strategy training. In line with the predictions, learners high on working memory capacity or reading skill could profit from learning strategy training in terms of learning outcomes and the quality of their navigational behavior. Learners low on working memory capacity or reading skill, in contrast, performed worse in both training conditions compared to the control condition. The improvement in learning outcomes for skilled learners as well as the impairment in learning outcomes for unskilled learners could be shown to be indirect effects mediated by the quality of navigational behavior.     

Access for All? Sozialinvestitionen in der frühkindlichen Bildung und Betreuung im europäischen Vergleich

The importance of investing in early childhood is widely acknowledged in policy circles. Particularly formal Early Childhood Education and Care (ECEC) is seen as key to creating equal opportunities and combating poverty by increasing educational achievement of children and supporting parental employment. This social investment perspective has in recent decades supported the rapid development and expansion of ECEC in most European countries. However, the international social investment discourse masks fundamental differences in European ECEC systems and detracts attention from the way ECEC is embedded in the wider welfare regime of a country. This paper critically examines the ‘social investment potential’ of ECEC systems by comparing an early social investment country, Sweden, with two ‘late movers’, the UK and Germany. It argues that investing in ECEC is not per se a panacea for social inclusion. To the contrary, if not combined with other, partly ‘traditional’ equality measures both in education and social protection, ECEC investment may have the opposite effect of increasing social inequality.
