In view of the research on education—and subject-related education in particular—that has been conducted in recent years,
it would seem useful to describe the current state and future trends of research on science teaching and learning. In the
present article, research findings are described, the deficits of science education are analyzed, and medium- and long-term
research goals are specified from the perspective of an interdisciplinary cooperative effort between specialists in the fields
of empirical educational research; the psychology of learning and instruction; and biology, chemistry, and physics education.

The stiffness measuring method for bicycle frames is not standardized, leading to a wide variety of test setups; they differ in many aspects such as applied load, support constraints and frame deflection measurement. The aim of this paper is to draw attention to this problem and to quantify the perturbing, unwanted side effects that influence the stiffness measurement of the bicycle frame. This is illustrated by developing a multi-purpose rating test method for bicycle frame stiffness. The proposed test rig design considers different aspects which should be taken into account when measuring the bicycle frame stiffness. In the experimental setup, it is observed that the contribution of the test bench compliance led to 21% difference in the frame stiffness results; the influence due to the head, the tube-bearing type the corresponding preload resulted in up to 19% difference in the stiffness results between the lowest and highest stiffness values measured; hysteresis effects caused by pulleys are estimated to introduce errors up to 11%; and the influence due to the operator variability and sensor accuracy is estimated to be less than 3%. 相似文献

The goal of this research was to highlight the role social regulatory processes play in making students’ teamwork in reciprocal teaching (RT) groups (a classroom activity in which students take the teacher’s role in small group reading sessions) effective. In addition to teamwork quality, we expected peer feedback to be a key factor in enhancing students’ reading comprehension achievements. Because previous research (Schünemann et al. in Contemp Educ Psychol 38:289–305, 2013) has shown that procedures of self-regulated learning (SRL) augment the effects of RT methods, we further assumed that such procedures would promote the quality of students’ collaborative efforts. In a cluster-randomized trial, students in 12 fifth-grade classes practiced a strategic approach to reading either in a RT condition or in a RT + SRL condition. In one of the 14 sessions, students’ interactive behavior was videotaped. Strategy use and reading comprehension were assessed at pretest, posttest, and maintenance. Performance differences between conditions were reliable only at maintenance. A multilevel mediation analysis showed that relative to RT students, RT + SRL students were better able to provide their teammates with informative feedback and organize their group work in a task-focused manner. Only feedback quality mediated the sustainability of treatment effects on strategy use and reading comprehension. In essence, this research suggests that effective reading comprehension trainings should integrate explicit instruction and practice in reading strategies, SRL, and focus on supportive peer processes in small groups with extensive instruction and practice in peer feedback. 相似文献

Social media are increasingly being used for educational purposes. The first part of this article briefly reviews literature that reports on educational applications of social media tools. The second part discusses theories that may provide a basis for analyzing the processes that are relevant for individual learning and collective knowledge construction. We argue that a systems-theoretical constructivist approach is appropriate to examine the processes of educational social media use, namely, self-organization, the internalization of information, the externalization of knowledge, and the interplay of externalization and internalization providing the basis of a co-evolution of cognitive and social systems. In the third part we present research findings that illustrate and support this systems-theoretical framework. Concluding, we discuss the implications for educational design and for future research on learning and collective knowledge construction with social media. 相似文献

This paper considers two paradigms of process-aware information systems (PAIS) that are used to share knowledge about planning and executing tasks. The case-based task management (CBTM) system is based on the transduction of execution protocols, so-called cases; and the pattern-based task management (PBTM) system is based on task patterns that are derived from cases but yield more abstract information. As user motivation to contribute to a collaborative task management system is a crucial factor for its success, we consider the different motivational requirements of CBTM and PBTM from a psychological point of view. Based on experimental findings about different factors that have been shown to enhance people's motivation to contribute their knowledge to a shared pool, we compare the two approaches and assess which one is more appropriate with respect to motivation. 相似文献

In this quantitative study, questionnaire data of fifty-two third- and fourth-grade teachers were analyzed using MANOVA tools. Teachers were asked to consider boys' and girls' achievement in mathematics, giving their views on the reasons for the students' successes and failures and describing their learning characteristics. Teachers thought that their average achieving girls were less logical than equally achieving boys. The girls were thought to profit less than boys from additional effort and to exert relatively more effort to achieve the level of actual performance in mathematics. Teachers rated mathematics as more difficult for average achieving girls than for equally achieving boys. With regard to girls, teachers attributed unexpected failure more to low ability and less to lack of effort than with boys. The results increase our understanding of stereotypical teacher beliefs that might help explain gender differences in achievement and in subsequent occupational choices.This revised version was published online in September 2005 with corrections to the Cover Date. 相似文献
