体育教材的属性与体育教学内容的选择

体育教材与体育教学内容既有联系又有区别。通过对体育教学内容的选择,按照一定的逻辑关系,而形成了体育教材。但体育教材所反映的体育教学内容是经过具体化了的教学内容,这一过程被称之为“教材化”,教材化后的体育教学内容变成了具体的项目和一些体育卫生保健的知识和方法。事实上对体育教材的选择只是对体育教材内容的选择,而这一选择必然依附于体育教学内容的选择。     

Accuracy of activPAL Self-Attachment Methods

This study examined the accuracy of self-attachment of the activPAL activity monitor. A convenience sample of 50 participants self-attached the monitor after being presented with written material only (WMO) and then written and video (WV) instructions; and completed a questionnaire regarding the acceptability of the instructional methods. Participants positioned the monitor lower than the instructed position on the thigh (WMO ?5.15 ± 2.75 cm, WV ?4.16 ± 2.15 cm; p = .008 difference) and approximately 2 cm laterally from the thigh midline (WMO 1.90 ± 0.92 cm; WV 2.08 ± 1.24 cm). The orientation of the device was positioned correctly along the midline (within < 1° of vertical). Acceptability was high for both instructional methods although preference was shown for the WV instruction. In conclusion, participants consistently self-attached the activPAL close to the intended placement with either instructional method. The addition of video instruction produced a slightly more accurate attachment and was preferred by the participants.

La Medusa by Caravaggio: characterisation of the painting technique and evaluation of the state of conservation

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.

我国校园足球骨干师资国家级专项培训实践反思与发展策论

摘要：我国校园足球骨干师资国家级专项培训于2015年6月在全国范围内展开,这是我国校园足球工作主导权转移到教育部门后对校园足球师资建设进行的初步实践,在培训理念、范围、模式、组织、数量、宣传等方面取得突破性进展和显著成果。但仍应对处于探索期的专项培训实践工作进行及时科学研判,为其可持续发展的策略选择提供借鉴。本研究通过文献资料法、访谈法、观察法、问卷调查法对专项培训工作的功能和问题进行客观分析,指出专项培训工作不仅具备显功能还具备潜功能,以及学员社会角色复杂化、教材缺失与部分课程设置偏倚、教师资源配置局限、学员评价制度简缺、激励不相容等问题是限制专项培训工作部分结构要素相互促进和功能发挥的凸显问题,并提出实现专项培训整体功能提升的思路和具体保障措施。
