Stichwort: Entwicklung im Erwachsenenalter

In this review article, “aging and learning” is discussed from the perspective of life span developmental psychology. Accordingly, aging is regarded as a continuous and multidimensional process which is characterized by a potential for change (plasticity) at all ages. We give an overview of age-related changes in two psychological domains which are considered to be highly relevant for learning processes, namely cognitive resources and resources related to personality, motivation and emotion. In addition, we describe developmental contexts which were shown to contribute to plasticity in the second half of life. The findings allow for the conclusion that learning is possible throughout the adult life span, albeit under changing conditions. Key implications for learning processes and learning contexts are discussed.     

A comparison of time-motion performance between age groups in judo matches

The aim of this study was to compare time-motion indicators during judo matches performed by athletes from different age groups. The following age groups were analysed: Pre-Juvenile (13-14 years, n = 522), Juvenile (15-16 years, n = 353); Junior (19 years, n = 349) and Senior (>20 years, n = 587). The time-motion indicators included: Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Groundwork Combat Time and Pause Time. Analysis of variance (ANOVA) one-way and the Tukey test, as well as the Kruskal-Wallis test and Mann-Whitney (for non-parametric data), were conducted, using P < 0.05 as significance level. The results showed that all analysed groups obtained a median of 7 (first quantile - 3, third quantile - 12) sequences of combat/pause cycles. In total time of combat, the result was: for Total Combat Time, Standing Combat Time and Gripping Time: Pre-Juvenile and Senior were significantly longer than Juvenile and Junior. Considering Displacement Without Contact, Junior was significantly longer than all other age groups. For Groundwork Combat Time, Senior was significantly longer than all other age groups and Pre-Juvenile was longer than Junior. These results can be used to improve the physiological performance in intermittent practices, as well as technical-tactical training during judo sessions.     

Mathe mit der Matte – Verkörperlichtes Training basisnumerischer Kompetenzen

Basic numerical representations are seen as the building block for the successful development of more complex numerical and arithmetic competencies. Extending previous studies focusing on improving basic numerical representations by means of embodied training schemes, the current study focused on an embodied training of children’s place-value understanding. In this vein, 49 secondgraders were trained on solving a number line estimation task by stepping on different fields of a dance mat allowing for separate estimations of tens and units with more effort needed to step on the tens. In a partially randomized cross-over design, two control conditions were used to controll for training effects caused exclusively by the numerical content trained or the use of the dance mat. Interestingly, results revealed specific training effects after both the embodied and the control conditions. However, training effects were significantly more pronounced after the embodied training, thereby providing further evidence for the benefit of an embodied training of the place-value structure of the Arabic number system.     

“Thinking About Thinking: It's not Just for Philosophers:” Using Metacognitive Journals to Teach and Learn About Constructivism

This article describes how Metacognitive Journals were used to teach prospective early childhood educators about constructivism. We emphasize the importance of modeling constructivist pedagogy and cultivating students' metacognitive potential. We share the effects on our students' learning and on our teaching. We also offer recommendations for teacher educators to incorporate Metacognitive Journals in their practice

Early Childhood Education as a Scientific Discipline: a state‐of‐the‐art perspective

The objective of early childhood education is to address the totality of issues and areas of activity relevant to young children. In spite of the considerable growth in knowledge concerning children and childhood, this objective has yet to be attained at the theoretical level. Proceeding from the vantage point of a retrospective of the conceptions of the two classical theorists, Rousseau and Frobel, the case is made for grounding early childhood education in the dimensions of subjectivity, intersubjectivity, society and history in order to be able to analyse its various tasks in their respective specificity and reciprocal dependence. The attempt is made to characterise the challenges facing such a theory and to outline the resulting systematic issues for a pedagogy of early childhood.
