This study investigated the relations between teachers’ pedagogical beliefs and students’ self-reported engagement in learning from texts with instructional pictures. Participants were the biology, geography, and German teachers of 46 classes (Grades 5-8) and their students. Teachers’ instructional behaviors and students’ engagement in learning from texts with instructional pictures were assessed by means of student ratings. Teachers’ beliefs about using texts with instructional pictures in their teaching were assessed by a self-report questionnaire. Results showed that the more teachers believed that students should be taught clear strategies on how to learn from texts with instructional pictures the more engagement was reported by their students. A multilevel mediation model showed that the association between teachers’ beliefs and students’ self-reported engagement was mediated by teachers’ perceived instructional behavior. 相似文献

La forte incitation actuelle de la part des autorités scolaires À recourir aux médias numériques en classe pose une nouvelle fois la question des arguments mis en avant. Et comme À l'occasion d'incitations antérieures (télévision scolaire, audiovisuel, informatique éducative), partisans et détracteurs s'appuient sur différents travaux qui attestent ou non de telle ou telle amélioration ou dégradation. Cette contribution se propose de montrer que les concepts et les modèles convoqués dans certains travaux, y compris les nÔtres et notamment le programme IN-TELE (Internet-Based Teaching and Learning), établissent entre les situations d'enseignement-apprentissage considérés comme classiques et celles qui sont supposées innovantes des distinctions parfois non pertinentes, qui se traduisent par des résultats outrageusement significatifs ou non significatifs. C'est donc le schéma modèle-observation-interprétation que nous interrogeons en suggérant que les outils de pensée disponibles et les procédés d'observation mis en m uvre aujourd'hui dans les différentes disciplines académiques qui s'intéressent aux usages pédagogiques des TIC contraignent, voire altèrent, notre compréhension des phénomènes éducatifs induits par les 'nouveaux' médias. Measuring the pedagogic effects of CIT: traps and illusions of cutting out actuality, and the administration of proof. The strong current encouragement of school authorities to have recourse to digital media in the classroom poses once again the question of the arguments that have been advanced. And, as at the tine of earlier encouragement, (for school television, audiovisual, educational informatics), partisans and detractors rely on different works which support, or not, such-and-such a praise or detraction. This contribution attempts to show that the concepts and the models brought together in certain works, including our own and notably the IN-TEL (Internet-Based Teaching and Learning) programme, which establish between the teaching-training situations considered as classic and those which are supposed to be innovative, distinctions which sometimes are not pertinent, which are translated into results which are outrageously significant – or non-significant. It is, then, the schema of model-observation-interpretation that we question in suggesting that the mental tools available and the observational procedures used today in the different academic disciplines which are interested in the pedagogic use of CIT constrain us to see, may even, alter our understanding of the educational phenomenon introduced by the 'new' media. Analyse der pädagogischen Auswirkungen von ICT (Information and Communcation Technologies) : Fallen und Illusionen aus der Wirklichkeit, sowie die Beweisführung. Die gegenwärtig stark geförderte Umstellung des Unterrichtsmaterials auf digitale Medien durch die Schulbehörden, stellt erneut die bereits vorgebrachten Argumente in Frage. Und wie schon bei vorangegangenen Einführungen (von Schulfernsehen, Audiovision, pädagogische Informatik) beziehen sich Befürworter und Gegner auf verschiedene Studien, die den Nutzen oder Unnutzen attestieren. Dieser Beitrag versucht aufzuzeigen, dass herangezogene Konzepte und Modelle in verschiedenen Arbeiten - einschliesslich der unseren und insbesondere des Programms IN-TELE (Internet-Based Teaching and Learning) - sich zwischen klassischen Bildungssituationen und denen als innovativ angenommenen wiederfinden - auch wenn diese Unterscheidung nicht immer treffend ist. Wir stellen also das Schema Modell-Observation-Interpretation in Frage, indem wir suggerieren, dass die heute applizierten Denkmodelle und Observationsverfahren - der verschiedenen akademischen Disziplinen, die sich für den pädagogischen Gebrauch von ICT interessieren - für unser Verständnis des pädagogischen Einflusses durch Multimedia hinderlich sind, ja wenn nicht sogar deren Gebrauch nachteilig beeinflussen. 相似文献

One important factor for effective operations in team sports is the team tactical behaviour. Many suggestions about appropriate players' positions in different attack or defence situations have been made. The aims of this study were to develop a classification of offensive and defensive behaviours and to identify team-specific tactical patterns in international women's volleyball. Both the classification and identification of tactical patterns is done by means of a hierarchical cluster analysis. Clusters are formed on the basis of similarities in the players' positions on the court. Time continuous data of the movements, including the start and end points during a pass from the setter, are analysed. Results show team-specific patterns of defensive moves with assessment rates of up to 80%. Furthermore, the recognition of match situations illustrates a clear classification of attack and defence situations and even within different defence conditions (approximately 100%). Thus, this approach to team tactical analysis yields classifications of selected offensive and defensive strategies as well as an identification of tactical patterns of different national teams in standardized situations. The results lead us to question training concepts that assume a team-independent optimal strategy with respect to the players' positions in team sports. 相似文献

The purpose of this study was to validate the calculation of reaction time (RT) and normalised power in block starts without considering arm ground reaction forces (GRFs) or using two kinematics-only methods. The RT and normalised power in the action phase were calculated using four different methods: using GRFs of arms and legs by force plates (whole F-based method), which can be regarded as the most valid method, using GRFs of legs captured by force plates (legs F-based method), using position of the centre of mass of the entire body captured by high-speed cameras (whole P-based method), and using only a partial subset of segment position (partial P-based method). Bland–Altman plots demonstrated that the RT of the legs F-based method was not similar to that of the whole F-based method: the mean difference was 7.4 ms and the 95% limits of agreement was?45.1 to 59.8 ms, and it was the least valid method for the calculation among the four methods. In contrast, the normalised power was more valid in the legs F-based method, followed by whole and partial P-based methods. This information will help researchers and practitioners to decide upon their analysis methods when analysing block start performance. 相似文献

Computer-based multimedia learning environments make it possible to present interactive animated pictures, which can be manipulated for active exploratory learning and which allow the dynamic behavior of complex subject matter to be displayed. Due to the large range of possibilities for exploratory interaction, such learning environments seem well suited for co-operative learning in which different learners analyse the presented subject matter from different perspectives. This paper first describes a theoretical framework for learning from texts and pictures together with an analysis of possible effects of animation and interactivity on knowledge acquisition. It then presents two empirical studies in which knowledge acquisition from interactive animated pictures was compared with knowledge acquisition from static pictures under the conditions of individual learning (Study I) and of cooperative learning (Study II). In Study I, learning with interactive animated pictures resulted in a superior encoding of detail information, but did not facilitate performance of mental simulation tasks. In Study II, learning with interactive animated pictures resulted both in inferior encoding of detail information and poorer results in mental simulations. These findings and the analysis of discourse protocols of subjects’ co-operation suggest that exploratory learning with interactive animated pictures is associated with extraneous cognitive load and that this load can be further increased by the co-ordination demands of co-operative learning. Although animated pictures may provide external support for mental simulations, they do not appear to be generally beneficial for learning, because they can prevent individuals from performing relevant cognitive processes. 相似文献
