化学基础实验教学方法的思考与探索实践

为了培养高素质创新型人才以适应新时期国家建设和社会发展的需要,高等教育正进行着全面的改革。如何进一步深化教学改革,提高教学质量,加快高等教育强国的建设步伐,高等教育教学方法的改革与创新至关重要。本文就在化学基础实验教学中对教学方法的思考和点滴实践进行了初步的总结。     

Validity and reliability testing of the Chinese (mainland) version of the 39-item Parkinson’s Disease Questionnaire (PDQ-39)

The 39-item Parkinson’s Disease Questionnaire (PDQ-39) has been tested in many languages, but not in Chinese mainland. We aimed to assess the Chinese (mainland) version of the PDQ-39. Seventy-one subjects with Parkinson’s disease (PD) completed the PDQ-39 and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36). All subjects were retested with the PDQ-39 a week later. The united Parkinson’s disease rating scale (UPDRS) and the Hoehn and Yahr (H &; Y) scale were also used to evaluate the subjects. Reliability was assessed by Cronbach’s α and intra-class correlation coefficient (ICC). Validity was examined in terms of agreement with SF-36, UPDRS, and H &; Y scales. The Chinese (mainland) version of the PDQ-39 demonstrated acceptable reliability (Cronbach’s α: 0.84–0.88; ICC: 0.56–0.82). The item-total correlations (0.33–0.88) and scaling success rates (77.56%) indicated satisfactory convergent and discriminant validity of the PDQ-39 items. The correlations between related constructs of the PDQ-39 and UPDRS (r=0.44–0.68) and between those of the PDQ-39 and SF-36 (r=(−0.46)-(−0.69)) were all statistically significant (P<0.01). Except for stigma, cognitions, and bodily discomfort, all other dimensions of the PDQ-39 significantly discriminated patients at different H &; Y stages indicated by the H &; Y scale. Although our observations indicate that some problematic subscales of this version of the PDQ-39 could be improved upon, this study suggests acceptable reliability and validity of the Chinese (mainland) version of the PDQ-39.

小提琴协奏曲《梁山伯与祝英台》演奏指法与弓法技术研究

演奏小提琴协奏曲《梁祝》,就要表现出中国小提琴音乐的民族风格特点,因而需要有重点有节制地运用滑指、科学地应用弓毛与琴弦的接触点、对古筝演奏技法也要借鉴等,在这些方面作出一定实验研究,以更能表现出该曲的情绪和激情,进而更好地突出民族风格。     

构建终身学习社会:高校继续教育大有作为

高等学校继续教育在终身学习成为一种趋势的前提,在分析自身办学问题及其面临困境的基础上,积极探索继续教育学院发展的策略,从校企合作、中外合作、教育质量、师资队伍、教学管理制度、网络教育等方面进行改革与尝试,努力推进终身学习社会的构建。     

绅士文化对战后英国高等职业教育醚影响及启示

二战后，英国政府为振兴科技、复兴经济大力发展高等职业教育，虽取得一定成绩，但相对于德、美等发达国家还有较大差距。英国绅士文化追求古典人文学科价值的传统以及追求教育的教养价值的社会心理是造成其高等职业技术教育发展比较滞缓的主要原因，这种影响广泛而深刻。对于我国而言，必须正视根植于民众心理的中国传统文化对职业教育的影响，挖掘其积极因素，引导职业教育朝良性方向发展。
