Wirksamkeit schulrelevanter Förderung in Kindertagesstätten

The present paper summarizes international and national research findings on the general and differential effectiveness of pedagogical work in early childhood education and care settings, evaluations of pilot projects on compensatory preschool education as well programs to support individual learning abilities. Based on these findings, the following conclusions are drawn: First, attending early childhood education and care settings at an early age (after the age of three) has a positive influence on the development of academic competences. Second, the effectiveness of these settings depends on the instructional quality, which could be considerably improved in Germany. Third, pilot projects on programs to support individual learning abilities could show that compensatory effects for disadvantaged groups of children exist, especially when they are interlinked with stimulating conditions in the family and at school. Fourth, effective training programs exist that can be implemented in early childhood education and care. However, a number of challenges need to be met before they can be successfully implemented.

Emotional and Behavioral Predictors of Preschool Peer Ratings

It was predicted that social cognitive, behavioral, and affective aspects of young children's social development would predict stable peer ratings of their likability. Measures of likability, emotion knowledge, prosocial and aggressive behavior, peer competence, and expressed emotions (happy and angry) were obtained for 65 subjects (mean age = 44 months). Sociometric ratings, particularly negative, were stable over 1- and 9-month time periods. Correlational analyses showed that emotion knowledge and prosocial behavior were direct predictors of likability. Prosocial behavior mediated the relations of gender and expressed emotions with likability (i.e., gender and expressed emotions were each related to prosocial behavior, and prosocial behavior was related to likability, but neither gender nor expressed emotions were related to likability with prosocial behavior partialled out). Knowledge of emotional situations similarly mediated the age-likability relation. Results uphold the early development of stable peer reputations and the hypothesized centrality of emotion-related predictors of likability.     

Comparison of visual,automatic and semiautomatic methods to determine ventilatory indices in 50 to 60 years old adults

ABSTRACT

The aim of this study was to compare different methods of detecting ventilatory indices (VI) and to investigate the impact of cardiorespiratory fitness (CRF) level on VI detection. Fifty females and fifty males completed a graded exercise test until volitional exhaustion with continuous gas-exchange measurement. The first and second ventilatory indices (VI-1, VI-2) were detected through different single automatic methods and through a semiautomatic method which combines visual and automatic detection methods. Additionally, the VIs were detected visually by two experts which served as the study specific gold standard. When comparing the semiautomatic method at VI-1 (intraclass correlation coefficients (ICC) 0.88 [0.81, 0.92], Bland-Altman bias ± limits of agreement (LoA) 55 ± 334 ml O₂ · min^?1) and VI-2 (ICC 0.97 [0.96, 0.98], LoA 1 ± 268 ml O₂ · min^?1) to the visually detected VI, high levels of agreements and no significant differences were found. This was not the case for any of the other automatic methods. Additionally, we couldn’t find any relevant differences regarding the CRF level.

We therefore concluded that the semiautomatic detection method should be used for VI detection, as results are more accurate than in any of the single-automatic methods.

‘Get real – we can't afford kindergarten’: a study of parental perceptions of early years services

The Australian Early Childhood Universal Access Agreement stipulates all children three and a half years of age and older access to 15 hours of a quality early childhood education programme. While most states and territories in Australia have a 90% or higher attendance rate, in 2010, in Queensland the attendance rate was a comparative 40%. This study explores parental perceptions of barriers to early years services in Queensland, Australia. Using content analysis, it explores comments from an online forum with 65 self-selected participants. Findings provide important insights for policy-makers interested in improving the quality of, access to, and participation in, early childhood education. Parents perceived the cost, limited number of places and small hours of kindergarten as the main barriers to accessing quality early childhood care in Queensland. Furthermore, they questioned the actual necessity of kindergarten programmes. Therefore, if the goal is to improve kindergarten attendance rates, it is important to gain an understanding of the reported perceived barriers in order to reduce these in the future.     

Neo-liberalism and universal state education: the cases of Denmark,Norway and Sweden 1980–2011

This article investigates neo-liberal policy on education in Denmark, Norway and Sweden. Traditionally, the edifice of the education system in these Scandinavian countries has been built on egalitarian values, but over the last 20 years they have increasingly adopted market-led reforms of education. The extent of neo-liberal policy varies between the countries. Denmark and Norway have remained more hostile toward such policies, thus protecting the education system from extensive deregulation and privatisation. Conversely, in Sweden a greater credence has been given to market forces, allowing private providers to play a much more significant role in delivering education services. This variation in neo-liberal policy on education in Scandinavia is usually ascribed to the increasing power of the Right. However, this article differs from most other education research in that it argues, on the contrary, that the answer is to be found mainly within the social democratic parties themselves.     

Who Needs What: Recommendations for Designing Effective Online Professional Development for Computer Science Teachers

The new Advanced Placement (AP) Computer Science (CS) Principles course increases the need for quality CS teachers and thus the need for professional development (PD). This article presents the results of a 2-year study investigating how teachers teaching the AP CS Principles course for the first time used online PD material. Our results showed that the teaching and computing background of teachers had a significant impact on the teachers' need for and use of online PD material. More specifically, novice CS teachers needed and used PD for developing their pedagogical content knowledge (PCK). Non-CS teachers needed and used PD materials emphasizing content knowledge. Experienced CS teachers believed they had little need for PD even though they were teaching a new course. Our study makes three recommendations for designing effective online PD for CS teachers: match PD to teachers' background, align PD with the course curriculum, and use effective motivational design to enhance teacher engagement.
