Der vorliegende Beitrag stellt Ergebnisse zum selbstregulierten und kooperativen Lernen aus zwei vom Institut für Schulentwicklungsforschung der Universität Dortmund durchgeführten Studien vor. Es handelt sich um die deutschen Ergebnisse der Second Information Technology in Education Study – Module 2 (SITES M2) der International Association for the Evaluation of Educational Achievement (IEA) und der Evaluation des Modellversuchs „Selbstlernen in der gymnasialen Oberstufe – Mathematik (SelMa)“

“Lost in Transition” - Tracing human responses to climatic and environmental change in the Pleistocene-Holocene transition in north-western Europe

This thesis presents a diachronic, cross-cultural comparative study of the five archaeological groups at the Pleistocene-Holocene transition in northwestern Europe, namely Late Federmesser, Ahrensburgian, Epi-Ahrensburgian, Long Blade and Early Mesolithic assemblages. This interface is characterised by intensive climatic warming which transformed vegetation and fauna. However, to date there is no consensus on the cultural developments at this interface. This thesis offers a ‘whole assemblage’ approach taking into account lithic assemblages, faunal assemblages, settlement patterns and environmental data, thereby departing from traditional classification systems which tend to focus on one classificatory element. The results suggest that the main change during this interface is a shift from highly mobile hunter-gatherer groups during the Lateglacial to more sedentary groups in the Early Mesolithic. However, the complex process of the “Mesolithisation” of northwestern Europe lasted several centuries which indicates that the broad synonymous use of the climatic Pleistocene-Holocene transition with the cultural Palaeolithic-Mesolithic transition should be avoided

People, lakes and seashores : Studies from the Baltic Sea basin and adjacent areas in the early and Mid-Holocene

During the Early and Mid-Holocene significant changes in the ecology and socio-cultural spheres occurred around the Baltic Sea. Because of the underlying climatic changes and thus environmental alterations, the area was the scene for various cultural developments during the period under investigation. In the course of the melting of the glaciers at the end of the last Ice Age, isostatic and eustatic movements caused continual changes to the Baltic Sea basin. Changes in water level, however, affected not only the Early and Mid-Holocene coastlines, but also the whole Baltic Sea drainage system, including large lakes, rivers and watersheds in the hinterland were also dramatically impacted by these ecological changes. Prehistoric people were thus affected by changes in resource availability and reduction or enlargement of their territories, respectively. In order to evaluate the impact of changes in the water and land networks on the environment, resource availability, and human behaviour, and to reconstruct human responses to these changes, we pursue an interdisciplinary approach connecting environmental and archaeological research highlighted through different case studies
