This study proposes that learning is a process of transitioning from one stage to another stage within a knowledge base that features concepts and relations. Drawing on the theories of expertise, this study explored two different models of learning progress (i.e., three- and two-stage models) in the context of classroom learning and identified a model that was a good fit to the data. Participants in this investigation included 136 students and 7 professors from six different universities in the United States. In order to detect and validate stages of learning progress in participants' written responses to an ill-structured and complex problem scenario, this study utilized Exploratory Factor Analysis (EFA) and the Continuous Log-Linear Cognitive Diagnostic Model (C-LCDM) method (Bozard, 2010). The results demonstrate that the three latent classes matched the three stages of the three-stage model. This study provides an account of a diagnostic model of learning progress and associated assessment methods, yet further studies are required to investigate different conditions.  相似文献

This design-based research study is aimed at two goals: (1) developing a feasible case-based instructional model that could enhance college students’ ill-structured problem solving abilities, while (2) implementing the model to improve teacher education students’ real-world problem solving abilities to deal with dilemmas faced by practicing teachers in elementary classrooms. To achieve these goals, an online case-based learning environment for classroom management problem solving (CBL-CMPS) was developed based on Jonassen’s (in: Reigeluth (ed.) Instructional-Design Theories and Models: A New Paradigm of Instructional Theory, 1999) constructivist learning environment model and the general process of ill-structured problem solving (1997). Two successive studies, in which the effectiveness of the CBL-CMPS was tested while the CBL-CMPS was revised, showed that the individual components of the CBL-CMPS promoted ill-structured problem solving abilities respectively, and that the CBL-CMPS as a whole learning environment was effective to a degree for the transfer of learning in ill-structured problem solving. The potential, challenge, and implications of the CBL-CMPS are discussed.

Effective and efficient measurement of the development of skill and knowledge, especially in domains of human activity that involve complex and challenging problems, is important with regard to workplace and academic performance. However, there has been little progress in the area of practical measurement and assessment, due in part to the lack of automated tools that are appropriate for assessing the acquisition and development of complex cognitive skills. In the last 2 years, an international team of researchers has developed and validated an integrated set of assessment tools called highly integrated model assessment technology and tools (HIMATT) which addresses this deficiency. HIMATT is web-based and has been shown to scale up for practical use in educational and workplace settings, unlike many of the research tools developed solely to study basic issues in human learning and performance. In this paper, we describe the functions of HIMATT and demonstrate several applications for its use. Additionally, we present two studies on the quality and usability of HIMATT. We conclude with research suggestions for the use of HIMATT and for its further development.  相似文献

Learning and transfer in subject-matter learning: A problem-solving model   总被引:1,自引:0,他引:1  
This paper points out that the growth of the cognitive movement, with its emphasis upon perception and memory, has been accompanied by a decrease in the study of learning, retention, and transfer as found in the traditional associationistic framework. Moreover, some critics have argued that the contribution of learning and memory research over the past century has been minimal. The present paper presents a general reconceptualization of learning and retention, making these concepts subordinate to the concept of transfer. This reconceptualization thus places emphasis upon prior knowledge, skills, attitudes, and other characteristics of the individual. In addition, it is argued that the general information-processing model of problem solving, especially as applied to ill-structured problems, provides a general conceptual framework for the study of learning, the model being especially useful when considering learning in academic subject-matter domains.  相似文献

人们在日常生活中需要不断地解决各种问题,正如波普尔所说"全部的生活就是问题解决"。问题解决,尤其是复杂问题的解决,已成为认知科学和学习研究中关注的焦点。复杂问题的解决是一个动态的复杂过程,需要综合运用多种认知和非认知成分。先前的研究已经提出了解决复杂问题的多种模型,给人们解决复杂问题提供了可依靠的支架。而案例知识作为一种典型性、叙事性、情境性、实践性、个人性、整体性的经验知识在问题解决中得到了广泛应用,已成为支持复杂问题解决的有效形式,具体表现为:支持问题境脉的阐释、支持问题的多视角认识、支持解决方案的生成、支持解决方案的确定以及支持对问题解决结果的评价。它正作为一种支持人们解决问题的资源,在现实中发挥越来越大的作用。  相似文献

Ill-structured problems, by definition, have multiple paths to a solution and are multifaceted making automated assessment and feedback a difficult challenge. Diagnostic reasoning about medical cases meet the criteria of ill-structured problem solving since there are multiple solution paths. The goal of this study was to develop an adaptive feedback mechanism that is capable of identifying and responding to novice physician misconceptions by mining the log trace data of user interactions in BioWorld, a computer-based learning environment designed to support medical students in regulating their own diagnostic reasoning. We applied a series of text pre-processing algorithms to extract the linguistic features that characterized symptoms identified by 30 medical students solving three endocrinology cases: diabetes mellitus (type 1), Pheochromocytoma, and Hyperthyroidism. A subgroup discovery mining algorithm was applied in two steps. First, rules were induced to predict an incorrect diagnosis submitted as the final solution for a case on the basis of symptoms highlighted by medical students as being pertinent, that were in fact not pertinent. Second, rules were induced to predict a distractor hypothesis (an incorrect hypothesis listed as the most probable) during the differential diagnosis process while solving the case. The rule set discovered through the subgroup discovery task was shown to predict both incorrect and distractor hypotheses set by novice physicians while solving the case. We discuss the implications in terms of developing an adaptive feedback mechanism that can detect physicians’ misconceptions and errors during problem-solving as a means to deliver prompts and feedback that promote the acquisition of metacognitive monitoring and control skills.  相似文献

Solving real-world problems is an effective learning activity that promotes meaningful learning in formal educational settings. Problems can be classified as being either well structured or ill structured. Internet information search approaches have an influential role to play in the successful performance of problem solving. A better understanding of how students differentially model information search strategies and movements in tackling well- and ill-structured problems is essential for creating engaging problem-solving environments for students. Static measures, such as the number of accessed nodes or links, or the number of times particular web browser function buttons are clicked, are limited in their ability to analyze attributes of information search patterns. A more dynamic and spatial representation of web movements and navigational patterns can be realized through the use of navigational paths as data. The two path-specific structural metrics that can be used to assess network-based navigational paths in relation to the structuredness of the problem-solving task are compactness and stratum. These metrics are, respectively, the indicators of the connectedness and linearity of network-based structures defining students’ online navigational visitations during the problem-solving sessions. This study explored the relevance and utility of these two metrics in analyzing the navigational movements of learners in seeking out electronic information to accomplish successful problem solving. The outcome findings of this study show that well- and ill-structured problems demand different cognitive and information seeking navigational approaches. The differing values of the two path metrics in analyzing the search movements organized by students in attending to well- and ill-structured problems were a direct result of the contrasting patterns of navigational path movements. The search patterns associated with well-structured problem solving tended to be more linear and less connected, whereas those related to ill-structured problem solving were more distributed and inter-connected.  相似文献

A major challenge for education and educational research is to build on our present understanding of learning for designing environments for education that are conducive to fostering in students self-regulatory and cooperative learning skills, transferable knowledge, and a disposition toward competent thinking and problem solving. Taking into account inquiry-based knowledge on learning and recent instructional research, this article presents the CLIA-model (Competence, Learning, Intervention, Assessment) as a framework for the design of learning environments aimed to be powerful in eliciting in students learning processes that facilitate the acquisition of productive knowledge and competent learning and thinking skills. Next, two intervention studies are described that embody major components of this framework, one focussing on mathematical problem solving in primary school, and a second one relating to self-regulatory skills in university freshmen. Both studies were carried out in parallel with the development of the framework, and were instrumental in identifying and specifying the different components of the model. They yielded both promising initial support for the model by showing that CLIA-based learning environments are indeed powerful in facilitating in students the acquisition of high-literacy learning results, especially the acquisition and transfer of self-regulation skills for learning and problem solving.  相似文献

良好的学习方法,不论是内在的或外在的认知过程,只要能够促进知识概念的学习、能达到长久的记忆和灵活的运用都可称之为学习策略。文献上认为图解法能帮助学生彻底了解基本概念、分析及解题能力,图像表征不只让同学印象很深刻,更能提升同学的逻辑思考能力。研究以侨光科技大学的会计信息系的学生为实验对象,以成本会计科目作为实验教材,研究发现融入图解法教学的实验组学生,无论在后测成绩、进步幅度等整体成效均优于控制组,显示融入图解法教学之解题策略有助于提高解题之成效。研究显示,学习能力对成本会计题的学习成效有两个影响:第一,在整体解题成效分析中显示,高学习能力组学生的进步幅度较小,而对低学习能力组学生的效益较大;其次,在三大类型题个别成效分析中显示,在简单基本题及中等困难题高学习能力组的后测成绩虽较高,但进步幅度较小,而在复杂计算题显示高能力组学生在本题的解题表现略优于低能力组学生。  相似文献

Online courses have been criticized for their focus on knowledge acquisition rather than on how to solve authentic complex problems, a skill that is increasingly being recognized as critical to meeting the challenges in the real world. The purpose of this study was to explore whether between‐group collaboration in project‐based online courses can promote student learning of complex problem solving. Eleven graduate students in an educational technology class participated in this study. Each group of three to four members designed and developed a 2‐week online mini‐course that was later implemented with classmates across groups. During the semester, students were encouraged to visit other group areas, discuss challenges, and share strategies in the online course environment. The results indicate that between‐group collaboration was effective in improving group processes, group project performance, individual student achievement, and confidence in complex problem solving in designing online courses.  相似文献

This article describes an exploratory study of question prompts and online mentoring (specifically a lateral or peer mentoring experience) in a field-based practicum that focused on teaching ill-structured problem solving of classroom discipline. Data were gathered on 26 in-service practicum teachers through online observations, online journal reports, questionnaires, and reflection logs. Results showed that the practicum teachers were successful in using the approach to plan and implement effective interventions for their students and that they perceived the online mentoring approach as being very beneficial in supporting their learning. A more detail analysis of seven practicum teachers and their mentors indicated that their mentors engaged in eight types of online mentoring functions; the most frequently used were asking practicum teachers to elaborate, and valuing the practicum teachers’ contributions. The influence of the mentoring functions on the seven practicum teachers’ ill-structured problem solving is also discussed. The study offers evidence that asynchronous online mentoring and question prompts can enhance the professional development of both practicum teachers and mentors by helping them learn about and apply intervention strategies in solving real-world teaching problems.  相似文献

Solving ill-structured problems is regarded as an important learning outcome in education as it allows learners to apply theories learnt into real practice. An asynchronous online discussion, with extended time for reflection, is an appropriate learning environment to engage learners in solving ill-structured problems. However, scaffolds may be needed to support learners in the online discussions. This study explores the effect of online scaffolds in supporting a group of graduate students' ill-structured problem-solving processes in asynchronous online discussions. The results of this study showed that the use of the online scaffolds did not lead to a significant difference in the number of ill-structured problem-solving processes. Further analysis revealed that wrong selection of message labels and under-usage of sentence openers affected the results of this study. Improvements for online scaffolds include having more precise message labels and sentence openers based on Socratic questioning approach.  相似文献

The purpose of this research is to investigate the relative effectiveness of using three different question-prompt strategies on promoting metacognitive skills and performance in ill-structured problem solving by examining the interplay between peer interaction and cognitive scaffolding. An ill-structured problem-solving task was given to three groups. One group (Type QP) received instructor-generated question prompts that guided the problem-solving process; the second group (Type PQ) developed their own peer-generated questions; another group (Type PQ-R) developed their own question prompts first and revised them later with an instructor-generated question list. In this study, students in the QP group outperformed those in any other groups. The results revealed that providing instructor-generated question prompts was more effective than letting students develop their own questions, with or without revision, in ill-structured problem solving. Analysis of each of the four problem-solving stages revealed that the provided question prompts were more helpful in the stages of justification, and monitoring and evaluating than student-generated prompts. The difference between PQ and PQ-R groups is not statistically significant either overall or in any of the problem-solving stages.  相似文献

The traditional approach to teaching science problem solving is having the students work individually on a large number of problems. This approach has long been overtaken by research suggesting and testing other methods, which are expected to be more effective. To get an overview of the characteristics of good and innovative problem‐solving teaching strategies, we performed an analysis of a number of articles published between 1985 and 1995 in high‐standard international journals, describing experimental research into the effectiveness of a wide variety of teaching strategies for science problem solving. To characterize the teaching strategies found, we used a model of the capacities needed for effective science problem solving, composed of a knowledge base and a skills base. The relations between the cognitive capacities required by the experimental or control treatments and those of the model were specified and used as independent variables. Other independent variables were learning conditions such as feedback and group work. As a dependent variable we used standardized learning effects. We identified 22 articles describing 40 experiments that met the standards we deemed necessary for a meta‐analysis. These experiments were analyzed both with quantitative (correlational) methods and with a systematic qualitative method. A few of the independent variables were found to characterize effective strategies for teaching science problem solving. Effective treatments all gave attention to the structure and function (the schemata) of the knowledge base, whereas attention to knowledge of strategy and the practice of problem solving turned out to have little effect. As for learning conditions, both providing the learners with guidelines and criteria they can use in judging their own problem‐solving process and products, and providing immediate feedback to them were found to be important prerequisites for the acquisition of problem‐solving skills. Group work did not lead to positive effects unless combined with other variables, such as guidelines and feedback. © 2001 John Wiley & Sons, Inc. J Res Sci Teach 38: 442–468, 2001  相似文献

This study investigated curriculum influences on student mathematics achievement by following two groups of students from fifth to sixth grade that were taught either the reformed curriculum or the conventional curriculum. Analyses with three-level modeling were conducted to examine learning outcomes of the students who were assessed three times over a period of 18 months. Achievement was measured with regard to computation, routine problem solving, and complex problem solving. Affective aspects included self-reported interest in learning mathematics, classroom participation, views of the nature of mathematics, and views of learning mathematics. The results showed overall improved performance among all the students over the time on computation, routine problem solving, and complex problem solving but not on the affective measures. There were differentiated patterns of performance between the groups. On the initial assessment, the reform group performed better than the non-reform group on calculation, complex problem solving, and indicated higher interest in learning mathematics. The two groups did not differ on the other achievement and affective measures at the first time of assessment. There was no significant difference in growth rate between the groups on the cognitive and affective measures except that the non-reform group progressed at a faster pace on calculation. Therefore, the non-reform group outperformed the reform group on computation at the third (last) assessment. These results are discussed with respect to the possible influence of the curriculum on student learning.  相似文献
