Motivation to learn as an outcome and determining factor of learning at school     

Erich Ramseier 《European Journal of Psychology of Education - EJPE》2001,16(3):421-439

This article defines and measures interest in lifelong learning in an effort to capture motivation as an outcome of schooling. As a school-internal counterpart, motivational orientations toward learning at school in general and toward mathematics learning in particular are introduced, based on Deci and Ryan’s theory of self-determination. Analysis within the Swiss TIMSS samples in lower and upper secondary education led to the definition of five such orientations with a constant structure across grades and levels of generality. Some orientations show a concrete focus like long-term utility. The validity of these constructs is examined by analysing the relation among these motivational orientations, their relationship to interest in lifelong learning and mathematics achievement as well as age and gender differences. As hypothesised, the higher a motivational orientation’s degree of self-determination, the higher is its correlation with interest in lifelong learning and mathematics achievement. Among age and gender differences, the contrasting behaviour of intrinsic and long-term utility orientation toward mathematics is notable. For example, the gender difference in long-term utility but not in intrinsic orientation increases from grade 6 to grade 8. These findings can be understood as an expression of gender-typical vocational aspirations which define technical and scientific fields as a domain for males and not for females.  相似文献

Reading achievement, metacognition, reading self-concept and interest: A study of German students in grades 3 and 4     

Christina E. van Kraayenoord  Wolfgang Erich Schneider 《European Journal of Psychology of Education - EJPE》1999,14(3):305-324

This study examined the reading achievement, metacognitive knowledge related to reading and memory, reading self-concept, and interest in reading of 140 German school students in Grades 3 and 4. The results indicated significant correlations between the metacognitive variables, motivational variables, and amongst metacognitive and motivational variables, as well as with reading achievement variables. The examination of good and poor readers showed significant differences in metacognitive knowledge of reading and memory, reading self-concept, interest in reading, and in teacher judgements of reading achievement between the groups. Differences between Grade 3 and 4 students were found in their word decoding skills, metacognitive knowledge about reading and memory, and teacher judgements of reading achievement. Results of the regression analysis indicated that reading achievement was predicted by grade level, word decoding, and teacher evaluations of reading achievement. The causal modelling indicated that motivation and metacognition affect reading comprehension in different ways. The findings are discussed in terms of future research and their educational implications.  相似文献   

Kinematic differences of elite and high-performance tennis players in the cross court and down the line forehand   总被引：1，自引：0，他引：1  

Landlinger J  Lindinger SJ  Stöggl T  Wagner H  Müller E 《Sports biomechanics / International Society of Biomechanics in Sports》2010,9(4):280-295

This study identified and compared the full body kinematics of different skill levels in the forehand groundstroke when balls were hit cross court and down the line. Forty-three three-dimensional retroreflective marker trajectories of six elite and seven high-performance players were recorded using an eight-camera 400 Hz, Vicon motion analysis system. The six highest horizontal velocity forehands with reliable kinematics of all participants were analysed for each specific situation (a total of 156 analysed shots). Significant differences (p < 0.01) and large effect sizes were observed between elite and high-performance players in linear velocity of the shoulder (2.0 vs. 1.2 m/s), angular velocity of the pelvis (295 vs. 168 degrees/s), and angular velocity of the upper trunk (453 vs. 292 degrees/s) at impact. The elite group showed a tendency towards higher racquet velocities at impact (p < 0.05). No significant differences were found in angular displacement of the racquet, hip alignment, or shoulder alignment at the completion of the backswing; nor did angular displacement vary significantly at impact. Irrespective of the group, different shoulder, hip, and racquet angles were found at impact, depending on the situation. The results should assist coaches when striving to improve their players' forehand.  相似文献   

The role of path length- and speed-related factors for the enhancement of section performance in alpine giant slalom     

Jörg Spörri  Josef Kröll  Hermann Schwameder  Erich Müller 《European Journal of Sport Science》2018,18(7):911-919

Knowing how to enhance alpine skiing performance is essential for effective coaching. The purpose of this study was to explore the role of path length- and speed-related factors for performance enhancement, while skiing on a homogeneously set/constantly inclined giant slalom course section (average gate distance: 27?m; offset: 8?m; slope inclination: 26°). During a video-based three-dimensional kinematic field-experiment, the data of six athletes who skied a two-gate section on four different types of skis were collected. The performance parameter analysed was section time. The performance predictors analysed were centre of mass (CoM), path length and the change in specific mechanical energy per entrance speed along the analysed section. Furthermore, since the current study examined alpine skiing performance within short sections, the skier’s entrance speed was also considered. Classified as a high-performance and a low-performance group based on section time, slow and fast trials significantly differed in CoM path length, the change in specific mechanical energy per entrance speed and entrance speed. The entrance speed of all trials analysed ranged between 15.25 and 17.66?m/s. In trials with both high and low entrance speed, the change in specific mechanical energy per entrance speed was found to be more relevant for the prediction of section time than CoM path length. However, further studies should investigate whether such a prioritization can be unrestrictedly generalized to other situations, such as entrance speeds, course sets, slope inclinations and competition disciplines different to those assessed in the current study.  相似文献   

Creatine kinase,myosin heavy chains and magnetic resonance imaging after eccentric exercise     

Stephan Sorichter  Johannes Mair  Arnold Koller  Erich Muller  Christian Kremser  Werner Judmaier 《Journal of sports sciences》2013,31(9):687-691

The aim of this study was to examine the relationship between myosin heavy chain (MHC) release as a specific marker of slow-twitch muscle fibre breakdown and magnetic resonance imaging (MRI) of skeletal muscle injury after eccentric exercise. The effects of a single series of 70 high-intensity eccentric contractions of the quadriceps femoris muscle group (single leg) on plasma concentrations of creatine kinase and MHC fragments were assessed in 10 young male sport education trainees before and 1 and 4 days after exercise. To visualize muscle injury, MRI of the loaded thigh was performed before and 4 days after the eccentric exercise. All participants recorded an increase ( P ? 0.05) in creatine kinase after exercise. In five participants, T2 signal intensity was unchanged post-exercise compared with pre-exercise and MHC plasma concentration was normal; however, they showed an increase ( P ? 0.05) in creatine kinase after exercise. For the remaining five participants, there was an increase in T2 signal intensity of the loaded vastus intermedius and vastus lateralis. These changes in MRI were accompanied by an increase in MHC plasma concentration ( P ? 0.01) as well as an increase in creatine kinase ( P ? 0.01). We suggest that changes in MRI T2 signal intensity after muscle damage induced by eccentric exercise are closely related to damage to structurally bound contractile filaments of some muscle fibres. Additionally, MHC plasma release indicates that this damage affects not only fast-twitch fibres but also some slow-twitch fibres.  相似文献   

Comparison between the force application point determined by portable force plate system and the center of pressure determined by pressure insole system during alpine skiing     

Kosuke Nakazato  Peter Scheiber  Erich Müller 《Sports Engineering》2013,16(4):297-307

The purposes of this study were (1) to compare the force application point (FAP) calculated by a portable force plate system and the center of pressure (COP) calculated by a pressure insole system during alpine skiing, and (2) to assess whether any statistical differences between FAP/COP characteristics were influenced by the skiing modes, skiers’ skill levels, or pitch of the slope. Seven expert and eight intermediate skiers performed 20 double turns with two different skiing techniques. Similarities between the time characteristics of both systems and repeated measures ANOVA were used for the statistical analysis. Time characteristics of both systems in the y direction (anterior–posterior) were highly comparable. The mean FAP and COP in the x direction (medial–lateral) were different in all skiing modes for the outer ski and for the inner ski for the expert skiers. The ranges of the FAP in both directions were greater than the COP in almost all conditions.  相似文献

Lernen in informellen Kontexten     

Wiebken Düx  Erich Sass 《Zeitschrift für Erziehungswissenschaft》2005,8(3):394-411

Zusammenfassung In der aktuellen Diskussion um Bildung und Lernen wird jetzt auch in Deutschland dem „Informellen Lernen“ verst?rkte Aufmerksamkeit gewidmet. Die Autoren halten diesen Begriff allerdings für unscharf und sprechen daher von „Lernen in informellen Kontexten“. Der Beitrag bezieht sich auf erste Ergebnisse eines empirischen Forschungsprojekts der Universit?t Dortmund und des Deutschen Jugendinstituts zu informellen Lernprozessen Jugendlicher in Settings des freiwilligen Engagements. Nach einer kurzen Darstellung des Forschungsdesigns werden, basierend auf einer ersten Analyse der in der Explorationsphase des Projektes geführten Interviews, die besonderen Strukturbedingungen der untersuchten Settings (Jugendverb?nde, Initiativen und Organisationen der politischen Interessenvertretung) sowie die Lernchancen in diesen Kontexten beschrieben. Im abschlie?enden Teil des Beitrags werden erste Ergebnisse zu den Wirkungen und Ergebnissen des Lernens durch Verantwortungsübernahme im freiwilligen Engagement vorgestellt. Bereits in der Explorationsphase konnten eine Reihe unterschiedlichster, im Engagement entwickelter Kompetenzen identifiziert werden. Neben der M?glichkeit personale, soziale, fachliche und organisatorische Kompetenzen zu erwerben oder zu erweitern, scheint eine freiwillige Verantwortungsübernahme vielf?ltige Chancen der Pers?nlichkeitsentwicklung, der biografischen Orientierung, der Sinnstiftung sowie der Teilhabe an der Erwachsenenwelt zu er?ffnen.   相似文献
