对“问题解决”的反思 总被引：6，自引：0，他引：6
“问题解决”是当前数学教育中的热点之一，但这一过程出现的5个问题值得反思：如何界定符合我国国情的“问题解决”内涵；“问题解决”与“问题提出”谁更具紧迫性；“问题解决”有异化为“题海战术”的危险；‘问题解决”是否就是解决“实际应用”；我国学生“问题解决”能力的现状到底如何。 相似文献

正确的问题表征也就意味着寻找到了正确的解决路径,因此外部表征对问题解决来说是特别重要的。帮助学习者能更清晰准确地识别表征问题,也就更好地支持了学习者的问题解决。文章从问题表征的心理学研究入手,分析了问题表征的信息来源和支持策略,并在此基础上设计了结合支持式表征和自主式表征两种支持模式的问题表征支持系统。 相似文献

The present research investigated analogical transfer during problem solving by bilinguals. In a study with 50 Spanish–English bilinguals, participants solved a target problem whose solution was similar to that of a preceding source problem. The source problem was always presented in the 2nd language; the target problem was always presented in the 1st language. The results showed that when participants understood a key structural feature shared by the source and target problems, they solved the target problem more often than others. Participants’ performance was not related to their proficiency in the language of the source problem (i.e., the 2nd language). 相似文献

有Neumann边界条件的抛物型方程的初边值问题是偏微分方程研究领域的一类经典的问题。这是由已知的边界条件和初始条件来求区域温度场的问题。若所给边界是固定区域的称为定边界问题,而现实中又有一类问题其边界随时间变化,这样的问题称为动边界问题。文章对于时动边界上的热传导问题的求解提出人工边界的方法,并在人工边界的基础上采用了差分方法求解此定解问题。为了检验方法的可行性,给出了数值模拟。 相似文献

Montgomery, H. & Allwood, C. M. On the Subjective Representation of Statistical Problems. Scandinavian Journal of Educational Research 22, 107‐127. Think aloud data from 19 subjects solving three statistical problems are reported. The data indicated that the problem solving process could often be regarded as a successive development of the problem formulation where each formulation tended to be on the same or on a higher qualitative level than the preceding formulation. Good problem solvers were found to differ from the poor solvers inasmuch as they (a) more often made an exhaustive definition of an essential concept mentioned in the problem, or (b) appeared to attend more to what was asked for in the problem. It was tentatively concluded that some of the erroneous problem solutions were due to a pure lack of reflection on how the solution of the problem should be related to the information asked for in the problem. For a problem, which was formulated in a seemingly ambiguous way, subjects’ knowledge of the underlying statistical model was positively related to the correctness of their problem interpretation. 相似文献

"发散-收敛"思维模式在数学解题中应用很多.它的实质是由于多个条件交叉,造成解题困难;将条件分开考虑解决较易,再在分别求解的基础上进行综合,找到问题的解答. 相似文献

问题解决的心理机制及其教学意义 总被引：1，自引：0，他引：1
问题解决是人类的一种基本学习活动,学生的问题解决过程是学生获取知识的主要途径。对问题解决的心理机制研究一直是心理学研究的热点,从问题解决心理学研究的不同发展阶段,反射出对问题解决本质认识的逐步深化。我们认为问题解决是在个体内部的信息加工与个体与环境的交互中完成的。而且,问题解决是非线性发展的,与问题的难度、主体的知识结构深度与复杂程度、策略的自动化程度等多种因素有关,完全按照一定的阶段论去设计问题解决的模式,会使问题解决的研究陷于僵化,如能用融合与发展的观点看待问题解决的心理机制,将有助于研究的深化。 相似文献

迷宫问题是《数据结构》中是作为栈的典型应用举例，且迷宫是以二维数组来存储的，表面上看似乎迷宫问题是一种特殊问题的解决方法，其实迷宫问题是一种特殊形式的图的问题。因此，迷宫问题总是可以转化为图的问题来解决的。讨论如何将迷宫问题转化成图的问题，以及如何利用图的算法来解决迷宫问题。 相似文献

A major impediment to problem solving in mathematics in the great majority of South African schools is that disadvantaged students from seriously impoverished learning environments are lacking in the necessary informal mathematical knowledge to develop their own strategies for solving non-routine problems. A randomized pretest–posttest control group design was used to empirically investigate the effectiveness of a strategies-based problem solving approach on the problem solving performance of 9th grade disadvantaged students. In this approach students receive explicit instruction on a wide repertoire of problem solving strategies. The results reported in this study show a significant improvement in problem solving performance when a strategies-based approach to problem solving was being implemented. Quantitative and qualitative analyses of the responses to the items showed how the treatment group students had internalized as part of their problem solving repertoire the strategies on which they had been explicitly instructed on. The findings of this study make a case for the adoption of this approach so that the gap between the student’s existing problem solving competence, and the cognitive demands of a problem solving task can be bridged. 相似文献
