Teaching thinking on a national scale: Israel's pedagogical horizons   总被引：1，自引：0，他引：1  

Anat Zohar   《Thinking Skills and Creativity》2008,3(1):77-81

Like other countries, Israel had its share of projects that see the implementation of inquiry and higher order thinking in schools as their main goal. However, although many of these projects were quite successful, they did not succeed in changing the bulk of teaching and learning in Israeli schools. This article describes a new national educational policy called “Pedagogical Horizons for Learning”. The goal of this policy is to move the whole educational system towards a focus on higher order thinking and deep understanding. Such a move must consider the knowledge gained from previous projects but it must also lean on strategies for implementing systemic educational change. Implementing the goals of the “Pedagogical Horizons for Learning” on a national scale requires simultaneous work on three-dimensions: (a) curriculum, learning materials and standards; (b) professional development; and (c) assessment. The article outlines the plan for each of these three-dimensions and provides some accounts of the first stages of the implementation process.  相似文献   

Themes of individualism, competition, and cooperation in teachers' stories     

Anat Kainan 《Teaching and Teacher Education》1992,8(5-6)

This paper deals with themes of individualism, competition, and cooperation in teachers' stories, as they are told in a high school staffroom. Teachers told stories to their colleagues and through these stories they presented their professional culture to themselves. The three themes of individualism, cooperation, and competition were woven together in the stories, stressing the importance of all three in the teachers' work. This triple theme is contradictory in essence and so it shows new difficulties in the teaching profession.  相似文献   

关于第一次国共合作失败原因的再思考   总被引：1，自引：0，他引：1  

徐可纯 《丹东师专学报》2002,24(3):40-43

关于第一次国共合作失败的原因,几十年来史学界已有定论,即客观上反革命力量大于革命力量,主观上由于以陈独秀为首的中共中央执行了右倾投降主义路线.本文试图从统一战线内部就国共两党的地位、中国共产党对改组后国民党性质的认识以及共产国际对中国革命的指导方针等方面对第一次国共合作失败的主观原因做更为深入的探讨.  相似文献

Contribution of Meta‐strategic Knowledge to Scientific Inquiry Learning     

Adi Ben‐David  Anat Zohar 《International Journal of Science Education》2013,35(12):1657-1682

The aim of the present study is to explore the effects of Meta‐strategic Knowledge (MSK) on scientific inquiry learning. MSK is a subcomponent of metacognition defined as general, explicit knowledge about thinking strategies. Following earlier studies that showed considerable effects of explicit instruction of MSK regarding the strategy of variables control, the present study explores whether similar effects are found in two additional scientific thinking strategies: Define Research Questions and Formulate Research Hypotheses. Participants were 119 eighth‐grade students from six classes of a heterogeneous school. Equal numbers of low‐achieving and high‐achieving students were randomly assigned into experimental and control groups. The findings showed dramatic developments in students’ performance following instruction. The effect of the treatment was preserved in a delayed transfer test. Our findings show that explicit teaching of MSK had a stronger effect for low‐achieving students than for high‐achieving students. The implications of the findings for teaching and learning in the context of scientific inquiry are discussed.  相似文献
