归纳法不等于归纳推理

在归纳逻辑中归纳法和归纳推理始终没有明确的界限 ,有人把两者看成是同一关系的概念 ,有人把两者看成是包含关系的概念。本文的观点是归纳法不等于归纳推理     

Grasping the essence of a science activity by using a model of pedagogical reasoning and action

This article grasps the essence of how a science content can be foregrounded by elaborating around concepts as floating and sinking, in relation to boats. The data consist of a videotaped authentic session with one preschool teacher and four children. The model of pedagogical reason and action [Shulman, L. S. 1987. “Knowing and Teaching: Foundations of the New Reform.” Harvard Educational Review 57 (1): 1–23. doi:10.17763/haer.57.1.j463w79r5645541] constitutes the analytical lens. The results show that the content is framed within a series of creative activities where children’s suggestions of how to act are crucial. The scientific content is approached according to the children’s verbalisations of their understandings. Furthermore, dialectical relationships become the main tool when making the content visible.     

基于事例推理的夹具设计研究与应用

根据基于事例的设计方法,提出采用工序件的特征信息和夹具的结构特征信息来描述夹具的相似性,并建立了包括这2方面主要特征信息为基础的事例索引码,设计了事例库的结构形式,创建了层次化的事例组织方式;同时,提出了基于知识引导的夹具事例检索算法,以及事例的修改和采用同族事例码进行相似事例的存贮,形成了基于事例推理的夹具设计.所开发的原型系统在型号工程夹具设计等项目的设计过程中得到了应用,并取得了令人满意的使用效果.     

A Study of Reasoning Talk Between Australian Chinese Mothers and Their Preschool Children: What Messages Are Mothers Sending?

The everyday conversations that occur between mothers and children, particularly those involving reasoning, are a major vehicle for the transmission of information and values to young children. This study explored the manner in which five Australian Chinese mothers engaged in reasoning talk with their preschool-aged children. A total of 83 instances of spontaneous reasoning talk were identified and analysed according to the manner in which the mothers justified their claims or statements, using Hasan’s reasoning structure framework to underpin the analysis. Both regulatory and nonregulatory contexts were analysed. The analysis revealed that in regulatory contexts, where a child’s behaviour is being controlled (for example, “eat up your dinner quickly”), mothers provided more socially based reasons to justify their directives. In nonregulatory contexts, such as shared reading, they used more logical reasoning based on universal laws of nature. The findings suggest that the reasoning talk that takes place between mothers and children provides a rich opportunity for mothers to convey their values to their children, with implications for children’s learning across a number of domains.

Practitioner tales: possible roles for research evidence in practice

ABSTRACT

This paper discusses, compares, and contrasts 4 different models for bringing evidence from randomised controlled trials (RCTs) into practice and into practical reasoning. I look at what questions the models can and cannot answer, what role they accord to RCT evidence, and what their possible attraction for practitioners might be. The models are those of Philip Davies, Nancy Cartwright, Stephen Toulmin, and Harald Grimen. The first 2 are constructed for the purpose of using evidence in practice, the 3rd is an adapted argumentation model, and the 4th is based on phronesis and represents an alternative to evidence-based education. It is argued that of these, Toulmin’s model has the narrative qualities that make it the most usable and practitioner-friendly model.     

Four Student Teachers' Pedagogical Reasoning on Functions

This study attempts to identify theinfluence of student teachers' subject matterknowledge for teaching on the process ofpedagogical reasoning. This influence isstudied through the way in which the concept offunction is presented to pupils in teachingthrough the textbook problems. Our findingsshow that the four student teachers in ourstudy differed in their subject-matterknowledge for teaching both in the differentaspects of concepts they emphasised and in theuse of a representation repertoire to structurelearning activities. All of this conditionedthe use of graphical and algebraic modes intheir planning of subject matter to bepresented to pupils. We explored also theinfluence of images of mathematics,teaching and learning on student teachers'organisation of the subject matter forteaching, but found this only slight. Finally,regarding the relationship between subjectmatter knowledge and pedagogical contentknowledge in student-teachers' ways of knowingthe subject matter, we offer some implicationsof these findings for mathematics teachereducation programmes.     

高中生物教学中学生理性思维的培养刍探

为在高中生物教学中实现对学生理性思维的有效培养,教师有必要对学生进行批判性思维能力、推理思维能力、建模思维能力等的协同培养,以此为学生理性思维能力的发展奠定基础。教师在高中生物教学过程中可以分别从实验教学、习题课、复习课入手,着手培养学生的理性思维,提高学生的理性思维能力。
