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.

Who Talks to Whom in Malawi's Agricultural Research Information Network?

Purpose: The sector-wide approach currently dominates as the strategy for developing the agricultural sector of many African countries. Although recognised that collaborative agricultural research is vital in ensuring success of sector-wide agricultural development strategies; there have been few efforts to understand the dynamics of national agricultural research/development networks in Africa. This study fills this gap by analysing the dynamics of networking and interactions between institutions in the National Agricultural Research System in Malawi. Design/Methodology/Approach: The study sampled actors in the National Agricultural Research System in Malawi, which included the main public agricultural research department, academic institutions, semi-autonomous research institutions, private companies and international agricultural research institutions. Data was analysed using Social Network Analysis. Findings: Results demonstrate that public agricultural research departments play a central coordinating role in facilitating information sharing; with other actors remaining on the periphery. However, it also shows the important role other actors play to relay information to a wider network of stakeholders. These secondary information pathways can play a very crucial role in ensuring successful implementation of the national agricultural research agenda. Practical implication: Policy-makers are called upon to integrate other research actors into the mainstream national agricultural research information network. This is vital as other research actors are, at the global level, increasingly taking up a greater role in financing and disseminating research and research results. Originality/Value: The study contributes greatly towards knowledge needed for continuing the transformation of African agricultural research; and aligning the African agricultural research vision and practice with the emerging global agricultural research paradigm.  相似文献

Examining the psychometric properties of the Infant–Toddler Environment Rating Scale-Revised Edition in a high-stakes context     

Rossana Bisceglia  Michal Perlman  Diana Schaack  Jennifer Jenkins 《Early childhood research quarterly》2009,24(2):121-132

The psychometric properties of the Infant–Toddler Environment Rating Scale-Revised Edition (ITERS-R) were examined using 153 classrooms from child-care centers where resources were tied to center performance. An exploratory factor analysis revealed that the scale measures one global aspect of quality. To decrease redundancy, subsets of items were selected randomly and by experts who rated items according to ease of administration and importance to quality. The shorter subsets demonstrated good discriminant validity, adequate to good psychometric properties, and high associations to the full ITERS-R score. They also demonstrated similar associations to staff education and staff-to-child ratio, as the full instrument. The best assessment of quality was demonstrated by the shortened subset that included items that assess both structural and process features of quality. Multilevel-analyses indicated that classrooms from the same providers score more similarly on ITERS-R than classrooms from other providers. The implications for using the ITERS-R in high-stakes contexts are discussed.  相似文献

Dynamics of the martial arts high front kick

Fast unloaded movements (i.e. striking, throwing and kicking) are typically performed in a proximo‐distal sequence, where initially high proximal segments accelerate while distal segments lag behind, after which proximal segments decelerate while distal segments accelerate. The aims of this study were to examine whether proximal segment deceleration is performed actively by antagonist muscles or is a passive consequence of distal segment movement, and whether distal segment acceleration is enhanced by proximal segment deceleration. Seventeen skilled taekwon‐do practitioners were filmed using a high‐speed camera while performing a high front kick. During kicking, EMG recordings were obtained from five major lower extremity muscles. Based on the kinematic data, inverse dynamics computations were performed yielding muscle moments and motion‐dependent moments. The results indicated that thigh deceleration was caused by motion‐dependent moments arising from lower leg motion and not by active deceleration. This was supported by the EMG recordings. Lower leg acceleration was caused partly by a knee extensor muscle moment and partly by a motion‐dependent moment arising from thigh angular velocity. Thus, lower leg acceleration was not enhanced by thigh deceleration. On the contrary, thigh deceleration, although not desirable, is unavoidable because of lower leg acceleration.  相似文献
