Making sense of research-based learning in teacher education     

《Teaching and Teacher Education》2020

Research-based learning challenges teacher educators to rethink pedagogical strategies, particularly so in a context where views about the role of research in pre-service teachers' professional development are contested. The views of academics implementing a research-based learning course in teacher education are examined through qualitative semi-structured interviews in order to understand how learning autonomy is fostered. Variation was found in what teacher educators thought the course was intended to achieve and in their teaching strategies. The basis for pedagogical decision-making appeared to be their own research learning experiences. Implications for teacher education and for implementing research-based learning more generally are discussed.  相似文献   

When teachers learn how to provide classroom structure in an autonomy-supportive way: Benefits to teachers and their students     

《Teaching and Teacher Education》2020

In two experimentally-based and longitudinally-designed studies, secondary-level PE teachers were randomly assigned to participate or not in a new intervention to help them learn all of the following: support autonomy, provide structure, and provide structure in an autonomy-supportive way. In Study 1, teachers who participated in the intervention showed longitudinal gains in all five hypothesized teacher benefits (e.g., teaching efficacy, job satisfaction). In Study 2, students of teachers who participated in the intervention showed longitudinal gains in all four hypothesized student benefits (e.g., classroom engagement, skill development). Overall, teachers and students benefited after teachers provided structure in an autonomy-supportive way.  相似文献   

CO_2、NH_3对YBa_2Cu_3O_(7-x)的结构及超导电性的影响     

覃作祥  张彦生 《科技通报》1991,(5)

以热重分析(TGA)、电阻测量和X射线衍射分析等方法,研究了CO_2与NH_3对YBa_2Cu_3O_(7-x)超导体结构稳定性及超导,电性的影响。当温度低于373K时,CO_2对YBa_2Cu_3O(7-x)的结构和超导电性无影响;当温度为523K时,CO_2使YBa_2Cu_3O_(7-x)的Tc下降;温度高于703K时,CO_2将很快破坏YBa_2Cu_3O_(7-x)的结构,并产生化学反应,生成新的化合物,在CO_2中存在的O_2与N_2对YBa_2Cu_3O(7-x)与CO_2的反应及反应产物的影响有较大差异。NH_3对YBa_2Cu_3O(7-x)结构稳定性的影响不大。  相似文献   

Mixed control of uncertain jumping time-delay systems     

Magdi S. Mahmoud  Fouad M. AL-Sunni  Yan Shi   《Journal of The Franklin Institute》2008,345(5):536-552

In this paper, we investigate a class of linear continuous-time systems with Markovian jump parameters. An integral part of the system dynamics is a delayed state with time-varying and bounded delays. The jumping parameters are modeled as a continuous-time, discrete-state Markov process. Employing norm-bounded parametric uncertainties and utilizing the second-method of Lyapunov, we examine the problem of designing a mixed controller which minimizes a quadratic performance measure while satisfying a prescribed -norm bound on the closed-loop system. It is established that sufficient conditions for the existence of the mixed controller and the associated performance upper bound could be cast in the form of linear matrix inequalities.  相似文献

Chronicling decentralization initiatives in the Philippine basic education sector     

Allan B. de Guzman   《International Journal of Educational Development》2007,27(6):613-624

The Philippine school system is considered as one of the largest in the world with 41,989 public elementary and secondary schools and 7790 private schools under the supervision and regulation of the Department of Education (DepEd Fact Sheet, 2005). This paper chronicles various decentralization initiatives carried out by the basic education sector in the country specifically along the areas of education financing, teacher effectiveness, curriculum development, textbooks and instructional materials, and school–community dynamics and student learning and assessment. This discourse culminates with the discussion of the lessons learned from a decentralized system of education for better school operation and management.  相似文献

谈大学生英语自主性学习能力的培养   总被引：6，自引：0，他引：6  

薛莲 《贵州教育学院学报》2004,20(6):19-20,58

随着语言教学不断向交际化方向发展，以学生为中心的课堂教学模式将课堂教学的中心由教师转向学生，这就意味着学生将承担更多的学习责任，即培养学生的自主性学习能力。在大学英语学习中，教师应帮助学生认识和挖掘其潜在的学习方法，培养学生良好的自主性学习能力。  相似文献
