改革对教师工作生活质量影响的跨文化比较研究

From the organizational behavior point, this study initially explored how factors of educational changes influenced on teachers. This study adapted the questionnaire made up by Consortium for Cross-Culture Research in Education (CCCRE), by cooperating with other countries, interviewed 513 teachers in nine countries. The main results are as follows: 1. Factors of educational changes include: domain, origin, objective, teachers' role, and timetable. Comparative results show: More similarities than differences tend to be presented in five factors. The detail results are: in domain, it mainly involves teaching change and learning outcomes change; in origin, the educational change most teachers participated was initialed by government; in role, teachers more act as the implementer; in timetable, gradual development is the chief characteristic. 2. The domain of change, origin and teachers' role has a significant impact on the quality of worklife of teachers, but timetable of change has not. The further study about the influence of educational origin on the quality of worklife of teachers shows: Changes of teachers' time -using, professional development were significantly impacted by the origin of education, and there is a significant difference in the change of time-using among nine countries. 3. Change on students, change on teachers' relationship are two important factors to impact the teachers' evaluation about educational change. But the teachers' evaluation, teaching age and the change on relationship are valid factors to predicate teachers participate in next educational change. 4. Compared with the educational change of other eight countries, the change in school system management and the change in learning outcomes are more carried on in China. There is no significance about other factors between China and overall nine countries. In China, the educational change has a more positive impact on teachers' time-using and professional development, but professional development is also a important factor to impact teachers' evaluation on change; however there is a negative relationship between the Chinese teachers' evaluation and the teachers' participation in next change.

Avoidant Learning Ability in Free Flying Housefly (Aldrichina grahami)by Electric Shock

下载PDF阅读器研究证实:蜜蜂和果蝇具有良好的学习记忆能力.利用自主改良的研究装置对另一种具有强大生存本能的双翅目昆虫--巨尾阿丽蝇(Aldrichina grahami)在自由状态下电击同避学习能力进行研究.结果表明,巨尾阿丽蝇具有良好的学习记忆能力,因为当刺激电压范围为5V到45V时,观察到巨尾阿丽蝇有显著的回避电刺激行为,而当电压达到60V时会受到明显伤害.由此推测,巨尾阿丽蝇适合作为神经系统研究的动物模型.该实验所采用的实验范例较以往有所改进,适合作为自由状态下研究昆虫的工具.
