大学生创造性社会问题解决的结构及其与心理健康的关系

以分层取样的方式选取541名大学生,采用社会性问题（故事）情境和SCL-90,考察了创造性的社会问题解决的结构及其与心理健康的关系。结果表明,（1）大学生创造性的社会问题解决策略的独创性、流畅性、变通性、适当性、有效性具有良好的内部一致性,通过探索性因素分析可抽取发散思维能力和适宜性两个主因素,累积解释率为89.68%;（2）创造性的社会问题解决与心理健康不存在显著相关;（3）计算机专业在SCL-90上属低分组的学生的发散思维能力显著高于高分组,管理专业学生问题解决总体上显著高于艺术和计算机专业。专业类型在创造性问题解决与心理健康之间具有调节作用,特定专业（如管理专业）的训练更可能改善创造性社会问题解决的策略（包括适宜性和发散思维能力）。

Young adolescents' metacognition and domain knowledge as predictors of hypothesis‐development performance in a computer‐supported context

Recently, the importance of ill‐structured problem‐solving in real‐world contexts has become a focus of educational research. Particularly, the hypothesis‐development process has been examined as one of the keys to developing a high‐quality solution in a problem context. The authors of this study examined predictive relations between young adolescents' metacognition, prior domain knowledge, and hypothesis‐development performance in a computer‐supported environment. Data were collected from 11‐ and 12‐year‐old Korean students (N = 101). A hypothesised model in predicting hypothesis‐development performance was evaluated using structural equation modelling. Both metacognition and prior domain knowledge significantly predicted young adolescents' hypothesis‐development performance. Implications and limitations of the present study and issues, including the experimental design, are discussed.     

Learning by analogy: Discriminating between potential analogs

The ability to successfully discriminate between multiple potentially relevant source analogs when solving new problems is crucial to proficiency in a mathematics domain. Experimental findings in two different mathematical contexts demonstrate that providing cues to support comparative reasoning during an initial instructional analogy, relative to teaching the same analogs and solution strategies without such cues, led to increased ability to discriminate between relevant analogs at a later test. Specifically, providing comparative gestures and visibly aligned source and target problems during initial learning led to higher rates of positive extension of learning to new contexts, and lower rates of susceptibility to misleading contextual features, both immediately and after a week delay.     

Teachers' approaches towards word problem solving: Elaborating or restricting the problem context

This contribution reports about a seven-month long video-based study in two regular Flemish sixth-grade mathematics classrooms. The focus is on teachers' approaches towards problem solving. In our analysis we distinguished between a paradigmatic-oriented (focus on the mathematical structure) and a narrative-oriented (focus on the contextual aspects of a problem) perspective on the problem-solving process. The findings have highlighted that the word problem-solving lessons were more dominated by a paradigmatic than a narrative approach and that interventions in which the relation between the mathematics structure and the realistic constraints of the problem context is addressed, were rare.     

高中生数学问题解决图示归纳方式的比较研究

类比迁移是进行数学发现和解决数学问题的重要思维方法,是培养数学创造性思维的一个重要途径.学优生更多的是依靠源靶问题的结构性特征,图示归纳的方式是消除性的;学困生往往依赖源靶问题的表面特征,图示归纳的方式是保留性的.数学教学中要加强学生正确运用类比迁移策略的意识,重视帮助学困生形成完善的数学知识网络.     

An example of the use of dynamic mathematics software to create problem-solving environments that serve multiple purposes

Problem-solving is regarded as a major component of mathematical performance, and well-designed problem-solving-based learning environments have the potential to assist students in developing a meaningful understanding of mathematical concepts and procedures. In this respect, given its various features, dynamic mathematics software has been regarded by mathematics educators as a promising tool for designing such environments. This study presents an example of the use of technology to create a dynamic learning environment through a discussion of the pedagogical value of a problem selected for an activity, followed by the implementation sequence of the problem-solving activity in the classroom. The students’ experiences during the implementation of the activity are also discussed; and finally, an additional version of the problem is recommended for use in the classroom.     

高等数学教学中数学思想方法作用的强化

数学思想方法在数学学习中起着重要作用．但在高等数学教学中,数学思想方法没有引起足够的重视从强化数学思想方法在数学问题解决中的作用、运用数学思想方法形成学生良好的认知结构、将数学思想方法作为鉴赏数学美的重要途径、重视类比法以外的其他思想方法的运用四个方面论述如何强化数学思想方法的作用．
