研究采用问题解决作业单和认知作业分析法考察了71名高中生解决学科问题时的图式归纳和迁移情况。结果表明:(1)在问题结构相同的情况下,增加问题表面相似性能促进问题解决迁移;(2)近类比条件有助于同一学科领域问题的迁移,而远类比条件可能更有助于跨学科领域问题的迁移;(3)近类比条件下,图式归纳水平对学科问题迁移的影响不大,远类比条件下,较高的图式归纳水平有助于学科问题解决的迁移。  相似文献

类比迁移是一种重要的迁移现象.在数学中,两个不同知识系统或两个不同问题之间的共同要素以及学习者头脑中的认知结构是影响类比迁移的两个主要因素;两个可类比的系统存在直接和间接两种关系,具有直接关系的两个系统存在着意义完全明确的类比关系,因此可直接进行类比推理,具有间接关系的两个系统,则需要对类比系统进行变换或重整化处理,建构一个中介系统;在类比迁移过程中,两个系统的共同要素是诱因,而过程性知识则起着支配作用。  相似文献

A new approach to change misconceptions of students is to build on ideas which match their students' existing intuitive knowledge. This can be done by analogy. The use of an analogical relation between the known and the unknown can help students learn new information and discard or modify misconceptions. Previous studies have confirmed this result in such areas as mathematics. The present study examined the use of analogical instruction to overcome misconceptions about conservation of matter. Students who understood the concept of conservation of matter when iodine was evaporated were able to transfer their understanding to the evaporation of acetone. This indicates that teaching by analogy can be an effective tool in science. The author is now studying the relative effectiveness of conflict training and learning by analogy.  相似文献

Analogical reasoning is believed to be an efficient means of problem solving and construction of knowledge during the search for and the analysis of new mathematical objects. However, there is growing concern that despite everyday usage, learners are unable to transfer analogical reasoning to learning situations. This study aims at facilitating analogy use for conjecturing in discourse-rich mathematics classrooms. We reconceptualized one of the traditional perspectives on analogical reasoning, called classical analogy, as a more dynamic one by providing learners with the opportunity to choose a target object and its property. While shifting attention to particular aspects of mathematical activity, we observed and analyzed how students became aware of hidden relational similarities and utilized them while weakening others to make conjectures. The detailed analysis of the constructs and processes of several similarity-making and conjecturing activities supports the significance of reconceived classical analogy use in mathematics classrooms.  相似文献

数学本质·认识论·数学观——简评"对数学本质的认识"   总被引:11,自引:8,他引:11  
数学本质是一个认识论问题,涉及经验知识与理论知识的关系,从其它角度提出质疑是文不对题的。数学本质是数学观的重要表现,它影响或决定着数学研究方法。研究数学本质是数学教育工作者的一个重要课题,不是“没有必要”的;培养学生树立正确的数学观是数学教师的一项重要任务,不是“无关紧要的”。数学发展的动力是实践,而不是归纳法。  相似文献

Although there has been considerable research into knowledge transfer for over a century, there remains a need for specific, validated techniques for teaching for transfer. This article reports on classroom-based research in which students learned about complex systems and climate change with agent-based computer models using two different instructional approaches based on productive failure (PF). In both PF approaches, students initially explored a problem space on their own and then received teacher-led instruction. One treatment group used climate computer models whereas the other group engaged in analogical comparisons between the same climate computer models and complexity computer models in different domains. The study found both groups demonstrated significant learning gains by posttest on assessments of declarative and explanatory knowledge and on within domain near transfer. However, students in the two models treatment group performed at a significantly higher level on an across domain far transfer problem solving task. Theoretical and practical implications are considered.  相似文献

During one school year, data were collected for vocational education students while they worked collaboratively on open-ended mathematics problems. In collaboration with participating teachers, instructional activities were designed with a twofold goal of modelling the process of problem solving and improving collaboration. Instructional activities were based on scaffolding instruction and included modelling problem solving, stimulating reflection, and giving feedback on the process of collaboration. These activities were gradually developed and implemented in collaboration with teachers who participated in the study. The main research question in this study was whether student collaboration while working in small groups creates a learning context where students work on open-ended problems and where instructional activities are aimed at stimulating collaborative problem solving in mathematics.To answer the research question, an experiment was undertaken in two classes in different schools. Two groups of students were videotaped while they tried to solve mathematics problems collaboratively. Observational data were analysed with a schema that was developed as part of this research. Analyses of the data showed that, in both groups, collaboration-oriented patterns increased during the school year. It is argued that the approach of gradual implementation of instructional activities that are designed in cooperation with participating teachers is effective in stimulating collaborative problem solving.  相似文献

This paper reports on different underlying structures of the derivative schema of three undergraduate students that were considered to be at the trans level of development of the derivative schema (action–process–object–schema). The derivative schema is characterized in terms of the students’ ability to explicitly transfer the relationship between a function and its first derivative to the derivative function and the second derivative. This conscious shift of properties of derivatives is differently manifested by the students in the trans level of development of the derivative schema and can be considered evidence of the different characteristics of the thematization of derivative schema. From here we suggest that there are different underlying structures in the constructed schema due to the consciousness in which students use the relations between a function and its derivative.  相似文献
