教师创造力内隐理论述评

创造力内隐理论(implicit theories of creativity)是指一般公众(专家和外行人)在日常生活和工作背景下所形成的,且以某种形式存在于个体头脑中的关于创造力概念、结构及其发展的看法(也称为"内隐观"或"公众观")。研究教师的创造力内隐理论有助于研究者了解教师对于创造力的观念以及他们对待创造性儿童的态度,从而把握教师实施创造性教学的状况,有针对性地对教师进行培训,改进教师的教学,从而有利于在教育教学中对学生创造力的培养。通过教师对创造力的理解,对创造性学生的态度及人格特征的认识,对创造力的培养等论述,以期有助于我国教师创造力内隐理论的研究。     

Using concept maps to elicit and study student teachers’ perceptions about inclusive education: a Tanzanian experience

In this study, concept map activities were used to trigger group discussions about inclusive education, with a focus on learners with disabilities. The participants were 226 Tanzanian student teachers. This article reports and discusses how the maps were analysed and what they indicate about the students’ thinking about certain aspects of inclusive education. The results also indicate that concept mapping as an activity in teacher education may be useful and engaging for students. It may help them to organise knowledge and make them aware of their own and others’ understanding of inclusive education practices. An analysis of concept maps constructed by student teachers may also help lecturers to identify views, misconceptions, knowledge gaps and insights about inclusion in education settings.     

An analysis of prospective teachers’ knowledge for constructing concept maps

Background: Literature contends that a teacher’s knowledge of concept map-based tasks influence how their students perceive the task and execute the creation of acceptable concept maps. Teachers who are skilled concept mappers are able to (1) understand and apply the operational terms to construct a hierarchical/non-hierarchical concept map; (2) identify the legitimacy of the constructed concept map by verifying its graphical structure and its educational utility; and (3) determine the inherent ‘good’ and ‘poor’ qualities of the resulting graphical structure to reiterate the ‘good’ qualities and to coach and provide feedback to alleviate ‘poor’ qualities.

Purpose: The purpose of this study was to investigate the nature of prospective teachers’ knowledge underpinning the technique used to construct concept maps and thus, explicate their facility to construct concept maps.

Sample, Design and Methods: Data consisted of 200 concept maps constructed by prospective teachers in an elementary science methods course.

Results: Analysis revealed that the prospective teachers had predominantly constructed either hierarchical and/or non-hierarchical concept maps. It is likely that their maps reflect the teaching that they themselves would have experienced in their science classrooms during their own education. Additionally, most of these concepts maps only contained the root concept and subordinate concepts and lacked directional linking lines, linking phrases, labelled lines and propositions.

Conclusions: We argue that teacher educators need to assess their prospective teachers’ understanding of concept mapping in relation to the legitimacy (the nature and quality) of the end-products (graphical structures) of such practices. Prospective teachers also need to understand the educational utility of concept mapping in terms of how these end-products impact and/or effectuate learning.     

An exploratory study of the knowledge base for science teaching

The purpose of this study was to describe the knowledge base of a group of science teachers in terms of their knowledge of the structure, function, and development of their disciplines, and their understanding of the nature of science. The study also aimed to relate the teachers' knowledge base to their level of education, years of teaching experience, and the class level(s) that they teach. Twenty inservice science teachers were selected to respond to a modified version of the Views on Science–Technology–Society (VOSTS) questionnaire to assess their understanding of the nature of science. The teachers then constructed concept maps and were interviewed. The concept maps were scored and the interviews analyzed to assess teachers' knowledge of the structure, function, and development of their disciplines. The teachers' knowledge base was found to be lacking in all respects. Teachers held several naive views about the nature of science and did not demonstrate adequate knowledge and understanding of the structure, function, and development of their disciplines. Moreover, the teachers' knowledge base did not relate to their years of teaching experience, the class level(s) that they teach, and their level of education. It was reasoned that teacher preparation programs are not helping teachers develop the knowledge base needed for teaching science. © 1997 John Wiley & Sons, Inc.

自信心标记概念图评价模式对高职学生学习效能的影响

自信心标记概念图评价模式可以体现出学习者对知识的理解程度和学习效能。考虑到课堂教学实施的可操作性,选用组件构建方式绘制概念图、采用BOPPPS教学模型开展教学,教师依据评价信息,包含学生对知识理解的正确性和自信心等内容进行有效指导,以对比教学试验的方式进行实证研究。依据试验数据,重点通过描述教师不同行为有效性的归一化学习增益、表现学习者理解差异性的判别值、展现学生理解一致性的命中率三个参数指标,验证翻转课堂采用自信心标记概念图评价模式的有效性。实验结果显示,实验班的归一化学习增益高于对照班,两组判别值和命中率参数均具有显著的统计学差异。由此可知,将知识理解的正确性和自信心作为学生的学习评价依据,并据此调整教师的指导策略,能够帮助学生获得更高的学习成就、增强学习信心。在高职教学中引入该评价模式,能更好地提升学生的学习兴趣和效率,培养其自主学习及问题解决的能力,达到最佳的教学效果。     

An innovative concept map approach for improving students' learning performance with an instant feedback mechanism

Concept maps have been widely employed for helping students organise their knowledge as well as evaluating their knowledge structures in a wide range of subject matters. Although researchers have recognised concept maps as being an important educational tool, past experiences have also revealed the difficulty of evaluating the correctness of a concept map. It usually takes days or weeks for teachers to manually evaluate the concept maps developed by students; consequently, the students cannot receive timely feedback from the teachers, which not only affects their learning schedules, but also significantly influences the students' learning achievements. In this paper, a computer‐based concept map‐oriented learning strategy with real‐time assessment and feedback is proposed in order to cope with the problems mentioned above. Our approach provides immediate evaluation of concept maps and gives also real‐time feedback to the students. An experiment has been conducted to evaluate the effectiveness of this new strategy in comparison with the conventional computer‐based concept map approach. It is found that our innovative approach can be significantly beneficial to promote learning achievements as well as the learning attitudes of students.     

Preservice teachers’ and teachers’ conceptions of energy and their ability to predict pupils’ level of understanding

The study examined (a) the extent to which teachers and preservice teachers understand the concept of energy and adhere to particular preconceptions associated with it; and (b) their ability to predict pupils’ knowledge and understanding of the same concept. Teachers and preservice teachers completed a test by indicating for each item what their response was and what an average sixth-grade pupil’s response might have been, and their predictions were compared to actual pupil performance. Results indicated that teachers’ and preservice teachers’ understanding of the concept was far from complete, and that teachers were, in general, more likely to overestimate pupils’ knowledge.     

Knowledge construction among teachers within a community based on inquiry as stance

This study explores the process of teachers' knowledge construction within a community designed based on the concept of inquiry as stance. Through close examination of three teachers' activities, the study investigates how teachers adapt and respond to such a community, whether their inquiry actually generates knowledge, and how it relates to their teaching practice. The findings demonstrate that inquiry as stance can serve as a framework for understanding how teachers can generate knowledge. However, the study contends that effort must be made if teachers are to assume an inquiry stance within their communities.
