This study examined how selected school mathematics textbooks in China, Singapore, and USA at the lower secondary grade level represent problem-solving procedures. The analysis of problem-solving procedures was carried out in two layers – general strategies, which adopted Pólya’s four-stage problem-solving model, and specific strategies, which consisted of 17 different problem-solving heuristics such as ‘acting it out,’ ‘looking for a pattern,’ ‘working backwards,’ etc. Both similarities and differences in the representation of problem-solving procedures in the textbooks across the three countries were revealed and compared. The possible reasons for the similarities and especially for the differences were explored. Suggestions about how to improve the representation of problem-solving in mathematics textbooks were provided at the end of the study.

Seven years of industrial experience followed by 30 years of academic research and teaching in structural engineering have led the author to believe that the prime objective of a university design course is not the design project itself but to train students to solve problems, as this will last them throughout their careers. It is shown how design projects can be formulated for the purpose of encouraging students to develop their problem-solving abilities. More importantly, a sequential assessment technique has been developed to quantify the students’ ability to both think and learn as well as the students’ grasp of the fundamental principles, all of which are required in problem-solving.  相似文献

Mathematical skills are essential for young people to attain academic results needed for further study and employment. Recent changes to the English National Curriculum have put an increased emphasis on pupils explaining the reasoning behind answers in maths. This is a skill that can be developed by improving metacognitive skills. The authors report on an in-class programme for small group work, based on prior studies that utilised metacognition to support maths. An evaluation was conducted including a focus group interview and observation, modelling and feedback sessions over approximately 10 weeks. Results from interview analysis showed a positive impact both on staff practice and pupils’ independent problem solving. Adaptations based on research findings were made to the programme and handbook. This programme represents a flexible, inclusive and low resource option for schools to address new challenges posed by the National Curriculum in times of budget cuts and increased time pressure.  相似文献

解决复杂情境中的问题是21世纪人才应具备的重要能力。翻转课堂作为一种聚焦问题解决的学习模式离不开有效的问题支架,但应用何种类型的问题支架以及如何应用问题支架仍有待进一步研究。在此背景下,通过文献述评、课堂观察、案例分析,借鉴问题支架认知分类观以及问题解决过程四阶段观点,构建了面向翻转课堂的课前“过程提示—细化提示—反思提示”问题支架、课中“问题表征—方案制订—方案分析—监控评价”问题支架以及课后混合的问题支架应用框架,并在小学三年级的信息技术课堂中开展准实验研究,分别从学习成绩、问题解决能力、学习态度三个方面进行了效果检验。结果显示:相对于控制组,实验组学生在学习成绩和问题解决能力表现方面较为优异,并且差异显著,实验组学生对使用问题支架持有积极的态度。  相似文献

An interdisciplinary science course has been implemented at a university with the intention of providing students the opportunity to develop a range of key skills in relation to: real-world connections of science, problem-solving, information and communications technology use and team while linking subject knowledge in each of the science disciplines. One of the problems used in this interdisciplinary course has been selected to evaluate if it affords students the opportunity to explicitly display problem-solving processes. While the benefits of implementing problem-based learning have been well reported, far less research has been devoted to methods of assessing student problem-solving solutions. A problem-solving theoretical framework was used as a tool to assess student written solutions to indicate if problem-solving processes were present. In two academic years, student problem-solving processes were satisfactory for exploring and understanding, representing and formulating, and planning and executing, indicating that student collaboration on problems is a good initiator of developing these processes. In both academic years, students displayed poor monitoring and reflecting (MR) processes at the intermediate level. A key impact of evaluating student work in this way is that it facilitated meaningful feedback about the students’ problem-solving process rather than solely assessing the correctness of problem solutions.  相似文献

问题解决研究的一个世纪:回顾与前瞻   总被引:5,自引:0,他引:5  
本文首先分析了问题解决的含义以及研究的重要性 ,然后重点梳理了过去一个世纪 ,特别是最近五十年里认知心理学关于问题解决研究的历史脉络 ,最后展望了今后的研究方向。笔者认为问题解决研究应该建立在信息加工与建构主义思想整合的基础上 ,坚持主客体相互作用观 ,把问题解决既看作信息加工过程 ,又视为知识建构过程 ,继续深入研究。  相似文献
