How different are ICT-supported pedagogical practices from extensive and non-extensive ICT-using science teachers?

This paper aims to understand the differences between characteristics of ICT-supported pedagogical practices of grade 8 science teachers of extensive and non-extensive ICT-using science teachers. The differences of the pedagogical practices are described in terms of innovative and traditionally important practice orientations. The innovative practice orientation reflects a demand for education in an information society (e.g. communication skills; ability to learn at own pace), while the traditionally important practice orientation (e.g. subject-matter knowledge) reflects teaching and learning in an industrial society. The purpose of this study was to explore differences between the ICT-supported pedagogical practices of extensive and non-extensive ICT-using science teachers. As part of the SITES 2006 study extensive ICT-using science teachers nominated their most satisfying pedagogical practice. Perceived student outcomes and teaching practices have been analyzed using the SITES 2006 database. In addition, the regular pedagogical practices of these science teachers were, using the SITES 2006 database, compared with the regular pedagogical practices of non-extensive ICT-using science teachers. The results show that although traditionally important practices within the context of ICT are still dominant in science education, changes in the equilibrium between traditionally important and innovative practice orientations are taking place across educational systems.     

Associations of Number Line Estimation With Mathematical Competence: A Meta‐analysis

The number line estimation task is widely used to investigate mathematical learning and development. The present meta‐analysis statistically synthesized the extensive evidence on the correlation between number line estimation and broader mathematical competence. Averaged over 263 effect sizes with 10,576 participants with sample mean ages from 4 to 14 years, this correlation was r = .443. The correlation increased with age, mainly because it was higher for fractions than for whole numbers. The correlation remained stable across a wide range of task variants and mathematical competence measures (i.e., counting, arithmetic, school achievement). These findings demonstrate that the task is a robust tool for diagnosing and predicting broader mathematical competence and should be further investigated in developmental and experimental training studies.     

Strategy development in children with mathematical disabilities: insights from the choice/no-choice method and the chronological-age/ ability-level-match design

This study investigated the strategy characteristics and development of children with mathematical disabilities (MD) in the domain of simple addition and subtraction, in terms of Lemaire and Siegler's model of strategic change, using the choice/no-choice method and the combined chronological-age (CA)/ability-level (AL)-match design. Four groups of children, matched on either CA or mathematical AL, solved a series of 36 problems with the bridge over 10 in four conditions. In the choice condition, children could choose between retrieval, decomposition to 10, and counting on to solve each problem. In the retrieval, decomposition, and counting conditions, they had to answer the same 36 problems using retrieval, decomposition to 10, and counting on, respectively. The results revealed clear differences in the frequency, efficiency, and adaptiveness with which the CA-matched children applied the available strategies. In contrast, we observed no differences in strategy frequency, efficiency, and adaptiveness between the AL-matched children. These results support the hypothesis that the strategy development of children with MD is marked by a delay rather than a specific deficit. Moreover, this study further documents the value of the methodology used to study children's strategy use and development in the domain of simple arithmetic.     

Understanding decision making in teachers’ curriculum design approaches

The goal of this study was to reach a better understanding of the intuitive decisions teachers make when designing a technology-rich learning environment. A multiple case-study design was employed to examine what kinds of factors (external priorities, existing orientations or practical concerns) influence design interactions of teams of kindergarten teachers. This study combines semi-structured interview data on teachers’ existing orientations with analysis of teachers’ design discussions during the design of learning material for a technology-rich learning environment. Three teams of teachers voluntarily participated. Findings on the existing orientations suggest that knowledge and beliefs about teaching and learning related to knowledge and beliefs on technology and early literacy. The analysis of teachers’ discussions revealed that the process could be characterized to a large extent as brainstorms; and that problems are not addressed in-depth. Rather they are resolved through brainstorming, and most argumentation falls in the realm of practical concerns: how to organize learning activities and how to respond to contingencies. The findings of this study suggest that teachers’ explicated design reasoning is mostly influenced by practical concerns, yet their own knowledge and beliefs play an important role at the start of the design process. However, these existing orientations as well as the practical concerns that emerge during the conversation tend to be narrow in scope. Theoretical and practical implications are discussed in light of how this study provides understanding of how to support these teachers.     

Activity theory as a tool to address the problem of chemistry's lack of relevance in secondary school chemical education

In a previous article, the problem of chemistry's lack of relevance in secondary chemical education was analysed using logical positivism as a tool. This article starts with the hypothesis that the problem can be addressed by means of activity theory, one of the important theories within the sociocultural school. The reason for this expectation is that, while logical positivism creates a divide between science and society, activity theory offers a model of society in which science and society are related. With the use of this model, a new course for grade nine has been constructed. This results in a confirmation of the hypothesis, at least at a theoretical level. A comparison with the Salters' approach is made in order to demonstrate the relative merits of a mediated way of dealing with the problem of the lack of relevance of chemistry in chemical education.
