Theory Competition and the Process of Change   总被引:1,自引:0,他引:1  
The reasons why many educational change initiatives have little impact are often framed in terms of either a poorly designed process on the part of the change initiator, or in terms of problems with the attitudes, skills and/or knowledge of those responsible for implementation. In this paper, we seek to integrate these two perspectives more closely by focusing on their interface and the competing theories frequently held by the change initiators and implementers. This concept of theory competition is illustrated with a case of a national literacy initiative in New Zealand in which the change initiators wished to raise the achievement of low performing students through the development of “learning-centred” leadership in schools and evidence-based practice. The desired outcomes were not achieved because theories about what it means to be a successful leader in such a situation, the data needed to undertake the type of evidence-based analysis envisioned and school personnel beliefs about the target students were understood differently by those responsible for initiating the change and those responsible for implementing it.  相似文献

《行政许可法》颁布后,公安机关的治安管理职能发生较大的转变,前置审批权削弱,临场检查任务量加大。公安机关的治安管理部门应通过工作重心从事前审批到事中监督和事后查处上的转移,改革传统的只管不查模式,提高治安管理工作效率。  相似文献

A common trend in higher education is the “flipped” classroom, which facilitates active learning during class. The flipped approach to teaching was instituted in a haematology ‘major’ class and the students’ attitudes and preferences for the teaching materials were surveyed. The curriculum design was explicit and involved four major components (1) the preparation of the students; (2) the weekly pre-class work; (3) the in-class active learning strategies and (4) closing the learning loop using formative quizzes. Each of these components is discussed in detail and was informed by sound pedagogical strategies. Several different sources of information and several freely available software tools to engage the students are discussed. Two iterations are reported here, with improved pass rate for the final examination from 47 to 48 % in the traditional class to 56–65 % in the flipped classroom approach. The majority of students (93 and 89 %) came to the class prepared, after viewing the screencasts and engaged fully with the activities within the face-to-face time. The students perceived that solving case studies (93 %) was the most beneficial activity for their learning and this was closely followed by the production of essay plans (71 %). The majority of students recommended that this approach be repeated the following year (69 and 75 %).  相似文献

Relations between self-reported parental reactions to children's negative emotions (PNRs) and children's socially appropriate/problem behavior and negative emotionality were examined longitudinally. Evidence was consistent with the conclusion that relations between children's externalizing (but not internalizing) emotion and parental punitive reactions to children's negative emotions are bidirectional. Reports of PNRs generally were correlated with low quality of social functioning. In structural models, mother-reported problem behavior at ages 10-12 was at least marginally predicted from mother-reported problem behavior, children's regulation, and parental punitive or distress reactions. Moreover, parental distress and punitive reactions at ages 6-8 predicted reports of children's regulation at ages 8-10, and regulation predicted parental punitive reactions at ages 10-12. Father reports of problem behavior at ages 10-12 were predicted by earlier problem behavior and parental distress or punitive reactions; some of the relations between regulation and parental reactions were similar to those in the models for mother-reported problem behavior. Parental perceptions of their reactions were substantially correlated over 6 years. Some nonsupportive reactions declined in the early to mid-school years, but all increased into late childhood/early adolescence.  相似文献

Because the counseling profession places high value on counselors possessing accurate self-awareness, this study investigated the differences and relationships between counselor education students' self-perceived and measured needs levels. A sample of 107 counselor students estimated their needs levels and then completed the Personality Research Form (PRF). Significant differences between their perceived and measured needs levels were found for 10 of the 14 PRF scales. Wide variations were evident in both perceived and measured needs levels. Significant correlations between perceived and measured needs levels percentiles for all 14 scales indicated consistency in over or under estimation of needs levels. Age and number of quarter hours completed were generally unrelated to accuracy of needs level estimation.  相似文献

在近代中国,法治作为一种观念、制度被比较普遍地理解和接受,是一个长期孕育的过程。这一过程可以分为三个时期:从鸦片战争至19世纪70年代、从19世纪80年代至清末新政时期、清末新政时期。清末建立法制社会的努力虽然没有成功,但其意义不能低估。  相似文献
