快乐体育思想与女生体育教学   总被引:1,自引:0,他引:1  
由于众所周知的原因,女生体育教学从形式到效果都不及男生,体育对女大学生的影响力十分有限,其中既有女性身体的客观因素,也有教学活动主体的主观问题.研究证明,注重兴趣的快乐体育是提高女生体育课教学效果的良方.  相似文献

The oil painting “La Medusa” executed by Caravaggio at the end of the XVI century on a wooden shield, was investigated by integrated physical–chemical and analytical methodologies in order to obtain scientific data capable of elucidating the state of conservation and the painting technique. Optical (OM) and electronic (SEM-EDS) microscopy, micro-FT-IR spectroscopy, gas chromatography–mass spectrometry (GC–MS) and pyrolysis GC–MS were applied on two microfragments and some organic samples obtained by solvent extraction using the swab cleaning technique. The obtained results indicated that Caravaggio probably reused an old shield as a previous gypsum preparation layer has been detected under the original painting layers. He used white lead, natural earths, verdigris and lead–tin yellow type I mixed with drying oils to paint. The considerable amount of amorphous particles of copper chlorides found in the green pigment verdigris suggests that it could have been produced according to the ancient recipe of verde salsum described by Theophilus. Mordant gilding has been identified on the upper part of the shield that can be related to an abandoned experiment to give the painting a mirror-like reflecting effect. Three different varnishes layers have been detected above the painted surface. The original and restoration varnishes have been identified and they contain a mixture of drying oil, mastic and turpentine and some beeswax. Cleaning tests, performed with different organic solvents, suggest the use of isopropyl alcohol as cleaning agent because it is less efficient in comparison to others solvents; thus it ensures a careful and controlled removal of the varnishes.  相似文献

In 1974–75 at the K.U.Leuven Project Work as Practicals was started in the first-cycle engineering curriculum aiming at (1) the integration of separate teaching items and 7lpar;2) the integration of theoretical and practical or numerical aspects of those items. After 4 years the evaluation of it was more than satisfactory. The teaching team of the Chemistry course has integrated this system of practicals into their normal chemistry practicals. In this way more students 7lpar;currently only 20%) would be able to profit from the new education curriculum, now called ‘Long-term Practicals’. About 20%of the sophomore student volunteers are working for about 15 hours spread over 5 weeks at a mini-research subject in close contact with the members of the teaching team, using the instruments of the Chemistry Division, reading the literature, writing a report after the practical work, with discussion and evaluation of the work with their team-leader. To make it possible that all the sophomore students (400 students in 1987)could profit from this new education system, the physics, mechanics, mathematics, etc. practicals have to adapt to the same integrated practical system.  相似文献

Training and contextual interference effects on memory and transfer   总被引:1,自引:0,他引:1  
An experimental intervention program to train subjects on coincidence anticipation and prediction skills was administered to novice females. An attempt was undertaken to study the effects of this sports training and training on laboratory tasks. According to Battig's predictions on the structure of practice sessions, both random and blocked contexts were presented. These acquisition contexts were viewed as orienting tasks that preceded sports training. The effects of high-contextual interference and sports training on acquisition, retention, and transfer were investigated. Practice conditions in the intervention were selected because of processing demands similar to random acquisition. Other research has shown that acquisition in random is influenced by sport-skill expertise and further indicates that processing of events occurring outside the laboratory influences performance of laboratory tasks. Observed results supported prior theoretical predictions and empirical findings on contextual interference. Predicted hypotheses were supported, and the effects of sports training were most profound during retention and transfer if the acquisition context for the trained subjects was random. Supported by prior research, activities performed outside the laboratory influenced performance on laboratory tasks. These results shift more emphasis on the learner as an active processor of information, which relates to Lee's (1988) views on transfer-appropriate processing.  相似文献
