Does e-government reduce the administrative burden of businesses? An assessment of business-to-government systems usage in the Netherlands

The reduction of the administrative burden on businesses is an important governmental policy objective. Electronic government is presented as a promising reduction strategy in many countries. Underlying assumptions and mechanisms are hardly ever made explicit and scientific evidence of successful implementations is scarce. This paper presents an assessment of business-to-government systems in use in the Netherlands. Results show that organizational characteristics are the most influencing factors of perceived burden reduction and implementation effectiveness. Whereas perceived organizational benefits positively relate to the overall confirmation of the former system adoption decision. Surprisingly the quantitative, usage related characteristics do not present any statistical relevance. These findings help us understand existing differences in appreciation between business and governmental representatives on the successfulness of e-government projects in reducing the administrative burden on businesses. Furthermore, research results can help to enhance the effectiveness of e-government policy and measurement instruments.     

Environmental education program evaluation in the new millennium: what do we measure and what have we learned?

We conducted a systematic literature review of peer-reviewed research studies published between 1999 and 2010 that empirically evaluated the outcomes of environmental education (EE) programs for youth (ages 18 and younger) in an attempt to address the following objectives: (1) to seek reported empirical evidence for what works (or does not) in EE programming and (2) to uncover lessons regarding promising approaches for future EE initiatives and their evaluation. While the review generally supports consensus-based best practices, such as those published in the North American Association for Environmental Education’s Guidelines for Excellence, we also identified additional themes that may drive positive outcomes, including the provision of holistic experiences and the characteristics and delivery styles of environmental educators. Overall, the evidence in support of these themes contained in the 66 articles reviewed is mostly circumstantial. Few studies attempted to empirically isolate the characteristics of programs responsible for measured outcomes. We discuss general trends in research design and the associated implications for future research and EE programming.     

Volkswirtschaftliche Erträge wirksamer Bildungsreformen zur Reduktion der Zahl der Risikoschüler

The weak educational performance of a noteworthy share of students in Germany is not only a problem in itself, in the sense of a missing capability for self-dependent participation in society. It also has substantial consequences for the economy. This article provides projections of the economic returns that can be expected from hypothetical educational reforms that succeed in effectively reducing the number of at-risk students. We start by discussing existing theoretical and empirical research on the consequences of educational competencies for economic growth. On this basis, we perform projections of the magnitudes of additional economic wealth that can be expected from effective educational investments. Apart from a summary of existing results of long-run projections to 2090, we also report new projections for shorter time horizons. The results, which report the economic returns to effective educational reforms that reduce the number of at-risk students by state (Bundesland) in 10-year intervals from 2020–2050, may prove particularly relevant in political and budgetary discussions. The article closes with a discussion of results from the economics of education literature on which educational reforms might be expected to be successful in reducing the number of at-risk students.     

Solitary and Collaborative Pretense Play in Early Childhood: Sources of Individual Variation in the Development of Representational Competence

This study evaluates sources of individual variation in child pretense play as an expression of emerging mental representation. Family sociodemographic characteristics, maternal personological characteristics, and maternal affective and cognitive play behaviors, as well as children's gender, language competence, and play, were examined simultaneously. Naturalistic child solitary play and child collaborative play with mother were videorecorded in 141 20–month-olds. Child solitary play, child-initiated and mother-initiated collaborative play with mother, and maternal demonstrations and solicitations of play were then coded into nonsymbolic and symbolic acts. Zero-order relations obtained between child play and, respectively, child gender and language, family SES, and maternal verbal intelligence, personality, physical affection, and play demonstrations and solicitations. Structural equation modeling supported the following unique predictive relations: Child language and mothers' symbolic play positively influenced child collaborative play, and child gender and mothers' verbal intelligence predicted child solitary play. Child gender and mothers' verbal intelligence and physical affection influenced mothers' play and so influenced child collaborative play indirectly. The cognitive advantages of child play and maternal influences on child play are placed in an adaptive parenting framework.     

The History of Industrial Research Laboratories as a Resource for Teaching about Science-technology Relationships

The history of industrial research laboratories offers a good opportunity for studying the complex relationships between science and technology. A good insight of these relationships is relevant for shaping a good concept of science and technology in science education and technology education. In the article, three different interaction patterns are derived from the history of industrial research laboratories (in particular the Philips Natuurkundig Laboratorium), namely (1) science as an enabler for technology, (2) science as a forerunner of technology and (3) science as a knowledge resource for technology. In science education and technology education these insights can be used for historical projects and for a use in design-and-make projects.     

Teachers’ beliefs systems about improving transfer of algebraic skills from mathematics into physics in senior pre-university education

Senior pre-university education (SPE) students experience difficulties applying mathematics to physics. This paper reports the outcome of an online explorative quantitative study of teachers' belief systems about improving transfer of algebraic skills from mathematics into physics, conducted among 503 mathematics and physics teachers working in SPE. We used a questionnaire with 16 beliefs about improving transfer, and asked teachers to select a top 5 and distribute 50 points among them. We used agglomerative hierarchical clustering to cluster qualified SPE teachers with more than 10 years of teaching experience. We found 3 large clusters, each containing naïve and desirable beliefs about transfer. These clusters turned out to be rather coherent sets of beliefs. Hence, these clusters can be interpreted as belief systems, to a certain extent justifying Ernest's [(1991). The philosophy of mathematics education. London: Falmer.] idea to cluster teachers based on their belief systems. We found relations between our groups and those of Ernest. Since naïve beliefs turn out to be weak in each cluster, science teacher educators can help science teachers to change their harmful naïve beliefs, into desirable transfer enhancing beliefs. Furthermore, we discuss some implications of our results for science teacher educators, curricula, teachers and textbooks.     

A fine-grained account of Prolog execution for teaching and debugging

A clear and consistent execution model of any programming language can lay the foundations not only for a good leaming experience, but also for a smoother design/edit/run/debug cycle. In this paper, we describe our attempt to construct precisely such a model for the logic programming language Prolog, based upon a notational extension of logic programming's traditional AND/OR trees. Our extension, called the AORTA diagram, is an And/OR Tree, Augmented to include invocation history status boxes at each node. This augmentation makes it possible to present a graphical view of Prolog execution which is very compact, yet which contains complete details of unification and control history, including multiple (backtracking) invocations and extra-logical features such as the cut. The paper describes our fine-grained view of Prolog execution in detail, and argues that this fine-grained view can readily be integrated into a coarse-grained model such as thatrequired for understanding the execution of very large programs. Indeed, our notation is already in use across a range of media, including textbook diagrams, video animations, and a graphical tracing and debugging facility running on modem graphics workstations.     

Relations between early reading and writing skills among Spanish-speaking language minority children

Although there is a growing body of literature on the development of reading skills of Spanish-speaking language minority children, little research has focused on the development of writing skills in this population. This study evaluated whether children’s Spanish early reading skills (i.e., print knowledge, phonological awareness, oral language) were related to their Spanish and English early writing skills using a sample of 554 children whose home language was Spanish. Multivariate regression analyses with simultaneous outcomes (Spanish and English invented spelling skills) were conducted to evaluate whether children’s early reading and writing skills were related across languages. Results indicated that children’s print knowledge and phonological awareness skills, but not oral language skills, were significantly related to their Spanish and English invented spelling skills. Spanish early literacy skills were not differentially related to Spanish and English reading and writing skills. The magnitude of the relations between print knowledge and oral language skills and children’s invented spelling skills varied as a function of child age; however, the magnitude of the relation between phonological awareness and invented spelling skills did not differ as a function of child age. Furthermore, results suggested that language minority children’s early reading and writing skills are related but distinct constructs and that children may be able to apply information gained from learning to read and write in their first language when learning to write in their second language.
