A historical overview of educational psychology

A historical review of educational psychology might improve understanding of current status and problems. Before American development of the field, the Greeks, Juan Vives in the 16th century, and Pestalozzi and Herbart in the 19th century applied psychological views to educational problems. Despite the absence of scientific psychology in 19th century America, normal schools offered courses purporting to be psychological in content; these courses were supported by textbooks on the subject. James began, and Thorndike developed, the discipline that by the mid-1920s had assumed much of its current form. Journals and academic departments appeared in the first quarter of the century also. The continuing search through the middle of the century for a satisfying professional organization reflected educational psychology's difficulties in establishing an identity. It is not clear even today that the field has “crystallized,” as one writer described it in the 1920s.     

Comparison of power and EMG during 6-s all-out cycling between young and older women

Abstract To investigate the effects of ageing on the neural control strategies governing sprint cycling on a friction-loaded cycle-ergometer, 10 older (aged 70-83yr) and 8 young (aged 19-35yr) healthy women completed seven 6-s all-out cycling trials against varying loads. Root mean square (RMS), median frequency and muscle fibre conduction velocity were determined from the vastus lateralis of the dominant limb during each pedal stroke. Peak power was 43% lower in the older group compared to the younger (p??0.05). ΔRMS from the first to the sixth second during each trial was found to increase significantly with the development of power output in both groups (p?相似文献   

On the Teaching of Science, Technology and International Affairs

Despite the ubiquity and critical importance of science and technology in international affairs, their role receives insufficient attention in traditional international relations curricula. There is little literature on how the relations between science, technology, economics, politics, law and culture should be taught in an international context. Since it is impossible even for scientists to master all the branches of natural science and engineering that affect public policy, the learning goals of students whose primary training is in the social sciences should be to get some grounding in the natural sciences or engineering, to master basic policy skills, to understand the basic concepts that link science and technology to their broader context, and to gain a respect for the scientific and technological dimensions of the broader issues they are addressing. They also need to cultivate a fearless determination to master what they need to know in order to address policy issues, an open-minded but skeptical attitude towards the views of dueling experts, regardless of whether they agree with their politics, and (for American students) a world-view that goes beyond a strictly U.S. perspective on international events. The Georgetown University program in Science, Technology and International Affairs (STIA) is a unique, multi-disciplinary undergraduate liberal arts program that embodies this approach and could be an example that other institutions of higher learning might adapt to their own requirements.
