基础教育阶段少数民族教育优惠政策的比较研究——以美国、英国和印度为例

美国、英国和印度是世界上较有影响的三个多民族国家,比较它们基础教育阶段的少数民族教育优惠政策可以发现以下规律:经费投入是少数民族教育优惠政策的应有之义;一国的少数民族来源会影响政策的理念;义务教育的普及情况会影响政策的侧重点;政策监管水平会影响政策的实施效果。     

责任伦理观的引入与自然辩证法教学改革

在社会生活和科学技术不断变化的新形势下,在自然辩证法教学中引入责任伦理观十分必要,可以进一步突显其科学？人文素质教育的双重功能。根据责任伦理观的内涵和现实国情,我们要积极培养理工科研究生对科学技术事业健全发展、社会进步和自然界的责任意识。为此,需要把责任伦理观融合到自然辩证法教学实践中,通过增补自然辩证法教学内容来体现责任伦理观;通过任课教师的教学理念来落实责任伦理观;通过案例教学来强化责任伦理观。     

Examining features of how professional development and enactment of educative curricula influences elementary science teacher learning

This research examines factors influencing elementary science teacher learning as they participate in professional development with and enactment of educative curricula in comparison with learning following limited professional development and enactment of traditional curricula. Using a randomized cluster design (125 teachers and 2,694 students in 4th—5th grades) that met the What Works Clearinghouse standards without reservations, teacher learning was conceptualized using four outcomes. Data were analyzed using standard single-level multiple regression models and possible mediation models for the teacher outcomes were considered using piecewise multiple regression and path analytic approaches. Treatment group teachers experienced greater increases in content knowledge, views of science inquiry, beliefs about reform-based teaching, and teaching self-efficacy than comparison group teachers. The findings indicate that what teachers learn from the combination of professional development and teaching with educative curriculum varies according to what their knowledge and beliefs are on entering the experience. Surprisingly, high entry-level self-efficacy was associated not only with lower learning gains for the teachers, but also for their students. Finally, teachers' space science learning and that of their students are implicated as mediators of the positive effect of the professional development and educative curriculum enactment on teacher beliefs about reform science teaching. This work refines and extends a theoretical framework of teachers' participatory relationship with curricula.
