Learning whom not to trust across early and middle adolescence: A longitudinal neuroimaging study to trusting behavior involving an uncooperative other

Longitudinal changes in trusting behavior across adolescence and their neural correlates were examined. Neural regions of interest (ROIs) included the medial prefrontal cortex (mPFC), dorsal anterior cingulate cortex (dACC), left anterior insula (AI), bilateral ventral striatum (VS), and right dorsal striatum (DS). Participants (wave 1 age: M = 12.90) played the investor in a Trust Game with an uncooperative trustee three times (1-year interval). Analyses included 77 primarily Dutch participants (33 females). Participants decreased their investments with wave. Furthermore, activity was heightened in mPFC, dACC, and DS during investment and repayment, and in right VS (investment) and AI (repayment). Finally, DS activity during repayment increased with wave. These findings highlight early–middle adolescence as an important period for developing sensitivity to uncooperative behavior.     

DEVELOPMENT, EVALUATION, AND VALIDATION OF A PAPER-AND-PENCIL TEST FOR MEASURING TWO COMPONENTS OF BIOLOGY TEACHERS’ PEDAGOGICAL CONTENT KNOWLEDGE CONCERNING THE “CARDIOVASCULAR SYSTEM”

One main focus of teacher education research concentrates on teachers’ pedagogical content knowledge (PCK). It has been shown that teachers’ PCK correlates with teaching effectiveness as well as with students’ achievement gains. Teachers’ PCK should be analyzed as one of the main important components to evaluate professional development programs. On this account, it is necessary to develop standardized measures of biology teachers’ topic-specific PCK that are labor-efficient. This paper presents a study on the development, evaluation, and validation of a paper-and-pencil test to measure biology teachers’ declarative PCK on the topic of blood and the human cardiovascular system. The development of the test was based, among other considerations, on a review of research literature on PCK and an analysis of 50 videotaped biology lessons. The final test instrument was comprised of 15 items distributed across 2 scales. The findings of the main study—with 93 preservice and in-service biology teachers and 12 biologists—confirmed that this measure of biology teachers’ declarative PCK was reliable, objective, and valid. In-service biology teachers scored higher on the test than preservice teachers (effect size Cohen’s d, 0.65) on one hand and, also, than biologists (Cohen’s d, 1.00) on the other hand. Future versions of this test should explore enlarging the scales and measuring procedural aspects of PCK.     

The use of school self‐evaluation results in the Netherlands and Flanders

This article presents the results of two studies on the use of school self‐evaluation in the Netherlands and Flanders. It focuses on which forms of instrumental use of school self‐evaluation results can be found in schools, and how differences in self‐evaluation use between schools can be explained. Results show that the instrumental use of self‐evaluation results in both contexts was limited. Results further show that differences in the use of school self‐evaluation results can be explained by differences in school organizational characteristics, implementation characteristics, and the characteristics of the school self‐evaluation itself. Implications for theory, policy, and practice are discussed.     

Towards a general modeling framework of resource competition in cognitive development

The current paper presents an integrated formal model of typical and atypical development based on the mechanisms of mutualism and resource competition. The mutualistic network model is extended with the dynamics of competition for limited resources, such as time and environmental factors. The proposed model generates patterns that resemble established phenomena in cognitive development: the positive manifold, developmental phases, developmental delays and lack of early indicators in atypical development, developmental regression, and “quasi-autism” caused by extreme environmental deprivation. The presented modeling framework fits a general movement towards formal theory construction in psychology. The model is easy to replicate and develop further, and we offer several avenues for future work.     

Promoting historical contextualisation in classrooms: an observational study

The aim of this observational study is to explore how history teachers promote historical contextualisation in their lessons. Historical contextualisation is the ability to situate phenomena and individuals’ actions in the context of time, historical location, long-term developments, or specific events to give meaning to these phenomena and actions. Using the Framework for Analysing the Teaching of Historical Contextualisation (FAT-HC), five trained raters observed eight history teachers twice. To further analyse the observation scores, the FAT-HC items were divided into eight categories while distinguishing between items that demonstrate historical contextualisation and items focusing on engaging students in historical contextualisation processes. The results indicate that the teachers in the sample did not explicitly promote historical contextualisation in their lessons. No teacher obtained a mean FAT-HC score >2.00 on a four-point scale. The teachers mainly demonstrated historical contextualisation, while engaging students in historical contextualisation processes was observed far less often. The findings can be used to help teachers formulate domain-specific instruction to promote students’ ability to perform historical contextualisation.     

A real options perspective on R&D portfolio diversification

This paper shows that the conditionality of investment decisions in R&D has a critical impact on portfolio risk, and implies that traditional diversification strategies should be reevaluated when a portfolio is constructed. Real option theory argues that research projects have conditional or option-like risk and return properties, and are different from unconditional projects. Although the risk of a portfolio always depends on the correlation between projects, a portfolio of conditional R&D projects with real option characteristics has a fundamentally different risk than a portfolio of unconditional projects. When conditional R&D projects are negatively correlated, diversification only slightly reduces portfolio risk. When projects are positively correlated, however, diversification proves more effective than conventional tools predict.     

II. DEVELOPMENT OF ADOPTED CHILDREN WITH HISTORIES OF EARLY ADVERSITY

This chapter first presents a review of research on the development of adopted children, focusing on meta‐analytic evidence and highlighting comparisons between adopted children with and without histories of early adversity. Some methodological issues arising from this literature are considered as well. Second, 7 longitudinal studies of adopted children's development are described, and the convergence of findings across the longitudinal studies and with the cross‐sectionally based meta‐analytic evidence is discussed. Third, the role of the adoptive family in supporting adopted children's development is explored.     

Source use and argumentation behavior in L1 and L2 writing: a within-writer comparison

The aim of this study was to test whether Cummins’ Linguistic Interdependence Hypothesis (LIH) might also apply to writing, by determining to what extent writers’ text quality, source use and argumentation behavior are related in L1 and L2, how effective writers’ behavior is and whether their L2 proficiency influenced the relations between them. To answer these questions, twenty students wrote four short argumentative source based essays each in L1 (Dutch) and four in L2 (English). A within-writer cross-linguistic comparison of their texts revealed that their L1 and L2 writing competencies appear to be related. Furthermore, writers’ source use behavior differed to some extent between languages, but the strong positive correlations found between source use features suggest that in most cases this was more a person than a language effect. Similarly, for argumentation behavior, results showed some learner specific features (e.g. inclusion of titles and reference lists), but differences between languages for others (e.g. the inclusion of both arguments and counter-arguments). Effects of the different source use and argumentation features studied on text quality were limited and no clear effect of L2 proficiency on writers’ behavior or their influence on text quality were found. Overall, in line with earlier research, these findings provide some additional support for Cummins’ LIH and the idea that writers might have a common underlying source for writing related knowledge and practices which they can apply in multiple languages.

     

Instructional design and project management: complementary or divergent?

This paper reports the results of a study to identify the extent to which organizations that develop educational/training products are committed to project management, as measured by their project management implementation maturity, as a methodology that is separate and distinct from the processes of instructional design. A Web survey was conducted among 103 public and private sector organizations worldwide that develop educational/training products. Results show no significant difference by project management maturity level in the roles of instructional designer and project manager, although there is some relationship between maturity level and how organizations perceive the skills/competencies of project managers versus those of instructional designers. Further, organizational decision-makers have very specific expectations about the formal education and training of educational/training product development project leaders. The findings should be of value to institutions of higher education in evaluating programs that prepare students for careers in instructional design.     

University Knowledge Production and Innovation: Getting a Grip

Today universities are increasingly seen as motors of innovation: they not only need to provide trained manpower and publications to society, but also new products, new processes and new services that create firms, jobs, and economic growth. This function of universities is controversial, and a huge and still expanding literature has tried to understand it. The approach of this paper is integrative; it uses the existing literature to answer a number of straightforward questions about the creation of innovations with university knowledge production: how does this happen, to what extent, and if it is desirable. In this way this article grounds the issue. Creating innovation with university knowledge production is relevant, justified and important but this has not been, is not and will not become the core function of universities. The existing literature, in other words, overestimates the importance of university knowledge production - in general, and for innovation in particular.
