面向问题导向学习的3C3R问题设计模型述评

问题导向学习是针对问题解决过程所进行的学习,对于问题导向学习而言,问题设计的有效性直接影响着问题导向学习的成功实施。研究已经表明,在所施行的问题导向学习中,设计的问题并非总是有效的。无效的问题不仅会影响到学生获得足够的领域知识,也会影响到学生问题解决能力或高阶思维能力的发展。美国北达科他州大学洪啤博士于2006年就面向问题导向学习提出了问题设计的3C3R模型。3C3R模型包括两类成分：核心成分和过程成分。核心成分是内容、情境和联系（content,context and connection）,这3个核心成分主要用来支持领域知识的学习,如概念、规则和原理知识。过程成分是探究、推理和反思（researching,reasoning and reflecting）,这3个过程成分则关注学习者的认知学习过程,用来支持学生应用所获得的领域知识来解决复杂问题,发展学生高级思维能力及学生自我导向能力。洪啤博士长期对问题导向学习、问题解决、问题类型与难度、系统思考与建模等主题进行研究,他提出的3C3R模型解决了教学设计者和教师在问题导向学习设计中的实际问题。本文将围绕问题导向学习的本质及其有效性来介绍了3C3R问题设计模型创建的基本观点、构成要件及其应用价值。     

Instructional design for distance learning

An intrinsic link exists between instructional design (ID) and distance learning (DL). Their inextricability in the real world raises specific problems of interest in the field of ID. In no other teaching/learning situation is ID so essential as in DL. The conditions of DL make it a necessity to have long-term instructional planning, cost analysis, curriculum and course development, instructional materials development and maintenance, delivery plans, and detailed evaluation rules. Without all of these components, DL simply could not happen. It took some time for this neccessity to be acknowledged, as can be seen in the history of DL. However, ID becomes even more critical as increasingly costly and complex means are used. Conditions of learning have special features in DL, such as the role of media, since the professor, teacher or instructor is replaced by media for either transmitting information or for organizing learning activities. In this paper, the term distance learning will be used to mean media-based, remote or asynchronous learning supported by an instructional system. This paper introduces general features of DL and examines essential aspects of ID for DL, with special emphasis on ID methodologies and on media selection.     

Designing for learning in the Yellow House: a comparison of instructional and learning design origins and practices

ABSTRACT

For the past two decades, there has been persistent debate around whether there is a difference between the fields of instructional design (ID) and learning design (LD). While differences in the two approaches are certainly apparent, there are cross-over points that can provide ID and LD researchers and practitioners with opportunities for dialogue about the purposes and remit of research-based practices for optimal design. Though potentially disruptive, initiating dialogues among learning and instructional designers could lead to more thorough and critical analyses of both ID and LD repertoires. Should boundary crossings occur, there is a potential for a third space for the contemplation, research, and practice of design. A goal of this article is to use the notion of Van Gogh’s Yellow House as an anchoring metaphor for the third space – a location for shared discourse, inspiration, collaboration, and challenge for a community of designers of/for learning. Using the impressionist and expressionist terminology to help elucidate the ways of thinking of designers of both traditions, this article examines the history, underlying philosophical approaches, methodologies, and design goals of ID and LD. We conclude that the emergence of a third space for design can help us move beyond the LD and ID dichotomies. We suggest that a socio-materialist perspective alleviates issues of incommensurability by acknowledging ontological multiplicity.     

Teacher learning in collaborative curriculum design

The Interconnected Model of Professional Growth (Clarke & Hollingsworth, 2002) was used to identify processes of teacher learning during the collaborative design of curriculum materials in the context of curriculum innovation. Nine published studies from six different countries about teachers’ collaborative curriculum design were analyzed to identify the learning processes that collaborative curriculum design fosters. It was concluded that the Interconnected Model of Professional Growth, although initially developed to recognize learning processes in individual teachers, can also be used to identify learning processes that are fostered by collaborative curriculum design in teams of teachers.     

Influence of problem familiarity on learning in a problem-based course

The results of an experimental study investigating the influence of problem familiarity on learning in a problem-based psychology course are presented. Participants worked with either a familiar or an unfamiliar version of the same problem. The following measurements were taken (1) a measure of problem quality as perceived by students, (2) number of explanations of the problem put forward by the students while discussing it, (3) quality of learning issues derived from the discussion, (4) amount of time spent on self-study, and (5) the amount of knowledge acquired as indicated by a test. The results demonstrate that participants in the familiar problem condition perceived the problem to be of higher quality than the participants in the unfamiliar problem condition. No significant differences in learning were found. The findings do suggest, however, that problems may be improved by making them more relevant to the everyday experience of students.     

The effect of problem-based learning on the metacognitive awareness of pre-service science teachers

ABSTRACT

The purpose of this study was to investigate the effect of problem-based learning (PBL) on the metacognitive awareness of pre-service science teachers. In the study, an experimental design with pre-test/post-test control group was used. A total of 51 junior pre-service science teachers participated in the study. The study was carried out over 10 weeks and within the scope of an environmental science course. During the study, lessons in the experimental group were processed using a PBL approach while lessons in the control group were processed using a traditional teaching approach. Data were collected through a personal information form and Metacognitive Awareness Inventory. Data were then analysed using PASW Statistics 18 (SPSS Inc.). The findings of the study revealed that PBL could be an effective intervention to promote metacognitive awareness towards procedural knowledge, planning and debugging. The results are discussed based on the findings of the study.     

The effect of problem-based learning on the environmental attitudes of preservice science teachers

This study attempted to investigate the effect of problem-based learning (PBL) on the environmental attitudes of preservice science teachers. In the study, an experimental design was used with a pre-test and post-test control group. In all, 51 junior preservice science teachers participated in the study. The study was carried out over 10 weeks within the scope of an environmental science course. During the study, lessons in the experimental group were processed using a PBL approach while lessons in the control group were processed using a traditional teaching approach. Data were collected through a personal information form and environmental attitudes inventory. Data were then analysed using PASW Statistics 18 (SPSS Inc.). The findings of the study revealed a statistically significant increase in favour of the experimental group preservice science teachers’ environmental attitudes. An increase in environmental attitudes was also found in the control group; however, this increase was not statistically significant. As a result, PBL was found to be more effective than the traditional teaching approach in the development of environmental attitudes in preservice science teachers.     

The critical, relational practice of instructional design in higher education: an emerging model of change agency

This paper offers an emerging interpretive framework for understanding the active role instructional designers play in the transformation of learning systems in higher education. A 3-year study of instructional designers in Canadian universities revealed how, through reflexive critical practice, designers are active, moral, political, and influential in activating change at interpersonal, professional, institutional and societal levels. Through narrative inquiry the voices of designers reflect the scope of agency, community and relational practice in which they regularly engage with faculty in institutions of higher learning.

Designing and implementing a case-based learning environment for enhancing ill-structured problem solving: classroom management problems for prospective teachers

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.

Imitative problem solving: Why transfer of learning often fails to occur

The paper presents empirical evidence for imitativeproblem solving and the Interpretation Theorydescribed in Robertson and Kahney (1996). According tothe theory beginners use imitation as their primary problem solving method when learning about an unfamiliar domain. Imitative problem solving can explain much of the evidence that analogical transfereven within a domain is often hard to find. The paperpresents an analysis of algebra word problems topredict in detail exactly where solvers will havedifficulty in using a worked out example to solveeither a close or distant variant of the problem type.In a 2 × between-groups design, secondary schoolstudents were given an explanation of an algebra wordproblem taken from Reed et al. (1985)or an explanation of the problem that also includedinformation about how the solution could be adapted tosolve a distant variant. They were then given eithera close or distant variant to solve. Results were inline with the predictions derived from theInterpretation Theory analysis.     

Epistemic profiles and self-regulated learning: Examining relations in the context of mathematics problem solving

Relations were examined between epistemic profiles, regulation of cognition, and mathematics problem solving. Two hundred sixty-eight students were sampled from undergraduate mathematics and statistics courses. Students completed inventories reflecting their epistemic profiles and learning strategies, and were profiled as rational, empirical, or both. Based on their profiles, 24 students participated in two problem-solving sessions. Episodes were coded for planning, monitoring, control, use of empirical and rational argumentation, and justification for solutions. For both self-reported metacognitive self-regulation and regulation of cognition during problem solving, students profiled as rational had the highest self-reported mean and actual frequency of regulation of cognition compared to students profiled as predominantly empirical. Moreover, students profiled as predominantly rational correctly solved more problems than the other two groups. Finally, students’ approaches to problem solving were consistent with their epistemic profiles. Relations are discussed in the context of various theoretical frameworks.

A design framework for educational hypermedia systems: theory, research, and learning emerging scientific conceptual perspectives

This paper focuses on theory and research issues associated with the use of hypermedia technologies in education. It is proposed that viewing hypermedia technologies as an enabling infrastructure for tools to support learning—in particular learning in problem-based pedagogical environments involving cases—has particular promise. After considering research issues with problem-based learning related to knowledge transfer and conceptual change, a design framework is discussed for a hypermedia system with scaffolding features intended to support and enhance problem-based learning with cases. Preliminary results are reported of research involving a new version of this hypermedia design approach with special ontological scaffolding to explore conceptual change and far knowledge transfer issues related to learning advanced scientific knowledge involving complex systems as well as the use of the system in a graduate seminar class. Overall, it is hoped that this program of research will stimulate further work on learning and cognitive sciences theoretical and research issues, on the characteristics of design features for robust and educationally powerful hypermedia systems, on ways that hypermedia systems might be used to support innovative pedagogical approaches being used in the schools, and on how particular designs for learning technologies might foster learning of conceptually difficult knowledge and skills that are increasingly necessary in the 21st century.

Chemistry problem solving instruction: a comparison of three computer-based formats for learning from hierarchical network problem representations

Within the cognitive load theory framework, we designed and compared three alternative instructional solution formats that can be derived from a common static hierarchical network representation depicting problem structure. The interactive-solution format permitted students to search in self-controlled manner for solution steps, static-solution format displayed all solutions steps, and no-solution format did not have solution steps. When we matched instructional time across the formats, in relation to the complex molarity problems rather than the dilution problems, differential transfer performance existed between the static-solution or no-solution formats and the interactive-solution format, but not between the static-solution format and no-solution format. The manner in which learners interact with the static-solution and no-solution formats depends on their level of expertise in the chemistry domain. With considerable learner expertise, provision of solution steps may be redundant incurring extraneous cognitive load. Absence of the solution steps may not have left sufficient cognitive capacity for germane cognitive load as some beginning learners lacked the prior knowledge to deduce the solution steps. Searching for solution steps presumably incurred extraneous cognitive load which interfered with learning and hence, in the interactive-solution format, it outweighed the benefit of engaging in self-regulated interaction with the content. Hence, cognitive load theory is a promising tool to predict the mental load associated with learning from the three alternative computer-based instructional formats.     

Instructional design for advanced learners: training recognition skills to hasten expertise

Expertise in domains ranging from sports to surgery involves a process of recognition-primed decision-making (RPD) in which experts make rapid, intuitive decisions based on recognizing critical features of dynamic performance situations. While the development of expert RPD is assumed to require years of domain experience, the transition from competence to expertise may potentially be hastened by training that specifically targets the recognition aspect of RPD. This article describes a recognition training approach that is based on expertise theories, research findings, and laboratory measurement techniques. This approach repurposes laboratory research tasks as deliberate practice training tasks. Although pioneered in sports expertise research, this approach is appropriate for pre-service and in-service professionals in a wide range of domains that involve rapid, recognition-primed decision-making.

The development of a robot-based learning companion: a user-centered design approach

A computer-vision-based method is widely employed to support the development of a variety of applications. In this vein, this study uses a computer-vision-based method to develop a playful learning system, which is a robot-based learning companion named RobotTell. Unlike existing playful learning systems, a user-centered design (UCD) approach is applied to assess the interface design of the RobotTell System so that the human–robot interaction can be enhanced during the design process. More specifically, the interface of the RobotTell system is assessed based on Nielsen's heuristics. Based on the results of Nielsen's heuristic evaluation, three versions of the RobotTell system were produced. The implications for the design of these three versions of the RobotTell system are discussed.
