面向高阶认知发展的成长式问题化学习(GPBL)研究--概念、设计与案例

促进学习者高阶认知和问题解决能力的发展,是当代教学设计的核心诉求之一。问题化学习(PBL)虽致力于此,但实践效果却不够理想。面向高阶认知发展的成长式问题化学习(GPBL),是在分析PBL的价值与困境的基础上所提出的一种扬长避短的教学设计方法。它将学习置于复杂而真实的问题空间中,使其难度可随学习者能力发展而循序渐进动态变化,进而促进其高阶认知发展。以此方法开展的“教育游戏设计”教学案例表明,学习者在复杂问题解决、远迁移、合作及编程等能力上,都有较为明显的发展,这在一定程度上验证了设计目的。     

A Problem‐based Learning Model for Teaching the Instructional Design Business Acquisition Process

There is a growing emphasis on utilizing a problem‐based learning [PBL] pedagogy to help instructional design students gain an understanding of the complex forces operating within an actual design environment. However, little literature exists to suggest that PBL is being used to teach the process by which instructional design firms and practitioners secure work—the Instructional Design Business Acquisition Process (IDBAP). This study outlines a conceptual framework for using an adapted problem‐based learning model for teaching the IDBAP, which consists of writing a response to a request for proposal (RFP), developing a working prototype, and orally presenting the solution. This study also examines the impact of a PBL pedagogy on students' perception of their confidence in solving instructional design problems. The results of this empirical research indicate that students who participate in a problem‐based learning pedagogy gain confidence in their abilities to solve instructional design problems, view themselves in emotional control when solving an instructional design problem, and are more inclined to approach similar problems in the future.     

Students’ Perception of Interdisciplinary,Problem‐Based Learning in a Food Biotechnology Course

Abstract: Students’ perception of 8 criteria (rationale of the problem; interdisciplinary learning; facilitator asked essential questions; learner's skills; assessments; facilitation procedures; team's use of resources [team collaboration], and facilitator within a problem‐based learning context) were assessed for a food biotechnology course that was part of a 3rd year biotechnology program. The mean score for “perceived learner's skills” was the lowest whereas those for “facilitation” and “facilitator” were the highest. Selected qualitative comments from students were also analyzed. This study demonstrated interdisciplinary learning as the students could make meaningful connections across different science disciplines. Further investigation is needed to develop possible strategies to accommodate the challenges in making meaningful connections across science disciplines as well as to develop a defined hybrid method for analysis of students’ responses.     

The role of the e‐tutor in synchronous online problem‐based learning: A study in a Master Public Health Programme

The aim of this study is to compare the role of the tutor in an online and a face‐to‐face problem‐based learning (PBL) session to shed light on potential differences of the tutor role in both settings. In this practice‐based study we compared the two groups with the same tutor undertaking the same module. Students completed questionnaires about tutor performance, student characteristics and the module. Marks on the end‐of‐module test were analysed. The tutor was interviewed about his expectations and experiences. One session of each group was recorded and analysed qualitatively. Results show tutor tasks appeared to be comparable in both settings with regard to “content and pedagogical content knowledge,” “group dynamics,” “process instruction” and “intermediary between faculty and students.” The face‐to‐face group rated tutor performance lower than the online students. Students and tutor identified the absence of nonverbal cues as a limitation of online PBL. In online sessions the tutor additionally provided technical support and moderated the chat box. It is recommended to involve an extra person in online sessions who is responsible for technical issues. This person could also check the chat box for messages of students. Future research should focus on the necessity of an extra tutor training for online sessions.     

Problem-Based Learning: What and How Do Students Learn?

Problem-based approaches to learning have a long history of advocating experience-based education. Psychological research and theory suggests that by having students learn through the experience of solving problems, they can learn both content and thinking strategies. Problem-based learning (PBL) is an instructional method in which students learn through facilitated problem solving. In PBL, student learning centers on a complex problem that does not have a single correct answer. Students work in collaborative groups to identify what they need to learn in order to solve a problem. They engage in self-directed learning (SDL) and then apply their new knowledge to the problem and reflect on what they learned and the effectiveness of the strategies employed. The teacher acts to facilitate the learning process rather than to provide knowledge. The goals of PBL include helping students develop 1) flexible knowledge, 2) effective problem-solving skills, 3) SDL skills, 4) effective collaboration skills, and 5) intrinsic motivation. This article discusses the nature of learning in PBL and examines the empirical evidence supporting it. There is considerable research on the first 3 goals of PBL but little on the last 2. Moreover, minimal research has been conducted outside medical and gifted education. Understanding how these goals are achieved with less skilled learners is an important part of a research agenda for PBL. The evidence suggests that PBL is an instructional approach that offers the potential to help students develop flexible understanding and lifelong learning skills.     

Factors Influencing Entering Teacher Candidates’ Preferences for Instructional Activities: A glimpse into their orientations towards teaching

The present study was designed to identify and characterize the major factors that influence entering science teacher candidates’ preferences for different types of instructional activities, and to analyze what these factors suggest about teacher candidates’ orientations towards science teaching. The study involved prospective teachers enrolled in the introductory science teaching course in an undergraduate science teacher preparation program. Our analysis was based on data collected using a teaching and learning beliefs questionnaire, together with structured interviews. Our results indicate that entering science teacher candidates have strong preferences for a few activity types. The most influential factors driving entering science teacher candidates’ selections were the potential of the instructional activities to motivate students, be relevant to students’ personal lives, result in transfer of skills to non‐science situations, actively involve students in goal‐directed learning, and implement curriculum that represents what students need to know. This set of influencing factors suggests that entering science teacher candidates’ orientations towards teaching are likely driven by one or more of these three central teaching goals: (1) motivating students, (2) developing science process skills, and (3) engaging students in structured science activities. These goals, and the associated beliefs about students, teaching, and learning, can be expected to favor the development or enactment of three major orientations towards teaching in this population of future science teachers: “motivating students,” “process,” and “activity‐driven.”     

Using Technology to Assist in Realizing Effective Learning and Instruction: A Principled Approach to the Use of Computers in Collaborative Learning

This article describes a principled approach to the design of computer-based tools for use in collaborative instruction. We argue that a project should progress through four steps: (a) making explicit the instructional requirements that serve as design goals for the project; (b) performing a detailed study of current educational practice with regard to these goals; (c) developing a specification based on the identified requirements/limitations of the instructional setting and the known capabilities of the technology; and (d) producing an implementation that allows for local adaptation to instructional practice. We propose six principles of effective learning and instruction, which we view to be the critical features of learning in complex and ill-structured fields. Next, a detailed case study is presented based on the preclinical training given to medical students in the first 2 years of medical school. The problems of providing adequate instruction in the preclinical years are described, as is an instructional method known as problem-based learning (PBL) that has been introduced to redress some of these problems. The product of this design process is a set of specifications for technical augmentations that we believe will serve not only the needs of PBL but also those of other methods of instruction that depend on collaborative, case-based, or student-centered learning.     

Teachers' Planning Processes: Does ISD Make a Difference?

Do teachers who have a formal educational background in instructional systems design (ISD) differ from those who do not in how they plan and implement instruction? This question guided this pilot study of ten volunteer teachers, five who had formal education in ISD and five who did not. An open and closed item questionnaire was sent to each subject and follow-up interviews were conducted. Teachers were asked about their general planning practices, written planning procedures, mental planning, and how they implement instruction based on their plans. Results indicated that nine of the ten teachers use general ISD skills and processes in planning. Teachers reported that they (a) analyzed learners' needs and abilities, and (b) used objectives to guide the instructional process, specifically for selecting learning activities and evaluation. While there were no major differences between the two groups in their submitted daily plans, the teachers with instructional design backgrounds were more specific in their open-ended responses about the use of instructional design for some aspects of planning (e.g., using hierarchies and taxonomies to sequence instruction), and the importance of consistency among objectives, learning activities, and evaluation. In addition, four of the five ISD teachers believed that knowledge of ISD has improved both their planning processes and their teaching. Because major differences between the two groups were not observed, much of the article focuses on teacher planning processes in general.     

A multimedia‐enhanced problem‐based learning experience in the Malaysian classroom

In this paper a multimedia project was incorporated into a problem‐based learning environment to examine how learning in multimedia could be enhanced through the use of problem‐based learning. Students in a second year course in the Faculty of Creative Multimedia (FCM) were assigned the problem‐based multimedia project, they worked in groups, solving the problem using the multimedia authoring process (MAP). This paper reports on the structuring of the student learning process, the impact of the problem‐based learning environment on student learning and the important skills such as creative and critical thinking, teamwork, communication, collaborative and problem‐solving skills that arose as the result of this intervention. In the process, a multimedia‐enhanced problem‐based learning (M‐PBL) model was created. The interrelationships between the teacher, students and technology in this learning mode were also established. A survey was conducted to assess the reactions and attitudes of the students towards this learning environment. The results obtained were positive and satisfactory.     

The effects of digital storytelling on student achievement,social presence,and attitude in online collaborative learning environments

This study investigated the effects of digital storytelling on student achievement, social presence, and attitude in online collaborative learning environments. Students in one middle school course were randomly assigned to one of the two treatment groups after they received initial general instruction regarding teamwork skills. The “digital storytelling-based online collaborative learning (DST-OCL)” and the “general online collaborative learning (G-OCL)” groups received subsequent associated skills training. The overall results indicated that after each group took part in the treatment during online collaborative learning activities, the “DST-OCL” groups had significantly higher social presence than the “G-OCL” groups. Specifically, using “DST-OCL” strategies was significantly more effective than using “G-OCL” strategies for improving the “online communication,” “interactivity,” and “privacy” components of students’ social presence in online collaborative learning environments. There was no significant difference between the two groups regarding student achievement and attitude. The findings of this study offer an insight into methods for using digital storytelling as an instructional strategy for improving online collaborative learning effectiveness.     

Incorporating a Modified Problem‐Based Learning Exercise in a Traditional Lecture and Lab‐Based Dairy Products Course

Abstract: A modified problem‐based learning (PBL) exercise was implemented in a food science Dairy Products course, which had previously been taught in the traditional lecture and laboratory format only. The first 10 wk of the course consisted of weekly lectures and laboratory exercises. During the remaining 3 wk, students were presented with a case study that described milk quality problems that could be encountered by the dairy industry. Each week, students received a set of case disclosures containing relevant information that assisted in solving the case. Students were asked to present their findings at the end of the course in the form of a written “consultant's report.” In addition, students were given a survey asking for feedback on the PBL exercise, and the usefulness of having the lectures and labs prior to the PBL experience. Eighty percent of the students found that lectures and labs provided them with sufficient background knowledge to understand and solve the PBL case, 70% found that the PBL reinforced course material covered during lecture and labs, 50% responded that PBL helped them develop new ways of reasoning about the subject matter and 65% reported that PBL taught them to think critically. Of the total students surveyed, 56% would prefer to participate in similar types of PBL exercises in the future. Incorporating PBL into traditionally taught food science courses can have a positive influence on the learning process.     

TradeSmith: An Exercise to Demonstrate the Illusion of Control in Decision Making

Resource allocation decisions are a fundamental class of problems common throughout a business and therefore are found throughout business school curricula. Entrepreneurs must allocate capital, financiers must allocation cash, and production managers must create the best mix of multiple‐use resources. Within this context, a business school's curriculum, instructional materials, and learning processes must consider the implications of individual decision making. Our traditional instructional content and delivery methods may effectively teach how to set up a decision “problem” and how to obtain an optimal answer. Yet, we may not be teaching a key underlying factor: that entrepreneurs, managers, and future leaders appear to have implicit cognitive biases, which discount information and skew individual decision making. The results of this study demonstrate that a phenomenon known as the “illusion of control” presents a fundamental challenge to the efficacy of formalized educational programs on decision making. TradeSmith was designed as a problem‐based learning exercise to elicit for the illusion of control in a basic, resource allocation, decision environment. The subjects in this study demonstrate a decision‐making pattern consistent with the “illusion of control” phenomenon. Finally, by revealing individuals' implicit design‐making paradigms, TradeSmith helps them experience key issues for managerial decision making.     

Clinical competencies and the basic sciences: An online case tutorial paradigm for delivery of integrated clinical and basic science content

Understanding the relevance of basic science knowledge in the determination of patient assessment, diagnosis, and treatment is critical to good medical practice. One method often used to direct students in the fundamental process of integrating basic science and clinical information is problem‐based learning (PBL). The faculty facilitated small group discussion format traditionally used for PBL is a significant challenge for faculty and facilities with a large class. To provide inductive learning to a large class early in the preclerkship curriculum, a series of online, case‐based tutorials was created using the method of inquiry‐based learning. The tutorial paradigm is designed to challenge students through a guided inquiry process in which clinical skills and basic science information are seamlessly joined. The psychosocial dimension of patient care is added to the documented case presentation of the tutorials in the form of patient/physician history taking and physical examination videos. These videos augment the written case with additional information providing the student with visual exposure in methods of patient communication and appropriate professional patient/physician interactions that address competencies of patient care, communication, and professionalism. The tutorials were made available via learning management system course sites. The study tracked usage of the tutorials by 270 first‐year medical students.

A professional development model for the positive practice of school‐based reading consultation

This paper reports on two years of a multiyear consultation/professional development project based on socioconstructivist principles (situated cognition, social context, and scaffolded instruction) that are consistent with key elements of positive psychology. The consultation model used a case analysis framework to engage 12 elementary school teachers in workshops, demonstration lessons, ad hoc inquiry groups, and coaching. Interview, questionnaire, and field note data from the participants identified “control and choice,” “focus on student needs,” “applicability to classroom practices,” “direct instruction of skills,” and “consultant feedback” as key elements of the model. Changes in classroom practices were reported by 78% of the participants with changes in confidence noted from pre‐ to posttests. Better learning for students was mentioned by 89% of the teachers. Discussion focuses on critical theoretical elements associated with positive psychology. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 51–65, 2004.     

Promoting Strategic Learning by Eighth‐Grade Students Struggling in Mathematics: A Report of Three Case Studies

Abstract. This article presents three in‐depth case studies focused on supporting students with learning challenges to learn math strategically. Participants were three eighth‐grade students enrolled in a learning assistance classroom who were of at least average intelligence but who were performing significantly below grade level in mathematics. These case studies document the processes by which these students were supported to self‐regulate their learning in mathematics more effectively. We begin by outlining important instructional foci in mathematics education for intermediate or secondary students with learning disabilities, along with what research indicates are effective instructional processes. In that context, we introduce the theoretical principles underlying the instructional model used here—Strategic Content Learning (SCL). Based on analyses of case study data, we describe how SCL instruction was structured to promote strategic learning. Throughout the discussion, intervention processes are described in sufficient detail to be of use to practitioners.

The 9-step problem design process for problem-based learning: Application of the 3C3R model

The design of problems is crucial for the effectiveness of problem-based learning (PBL). Research has shown that PBL problems have not always been effective. Ineffective PBL problems could affect whether students acquire sufficient domain knowledge, activate appropriate prior knowledge, and properly direct their own learning. This paper builds on the 3C3R problem design model, which is a systematic conceptual framework for guiding the design of effective and reliable problems for PBL. To help practitioners apply the 3C3R model, this paper introduces a 9-step problem design process. The initial steps guide an instructional designer through analyses on learning goal, content, and context to help select problems. Later steps ensure that the problem appropriately affords the specifications identified in the analyses. The last two steps incorporate a reflection component, as well as ensure the integrity of the 3C3R components in the problem.     

Using Socioscientific Issues to Enhance Students’ Emotional Competence

The premise of our study is that emotional competence (EC) serves as a foundational contributor to the achievement of science education goals in the context of socioscientific issues (SSIs). EC is a set of abilities necessary to accomplish adaptive goals in emotionally arousing situations. We contend that the development of EC is conducive to learning and character development in the SSI context. Therefore, we set out to develop and implement an EC intervention SSI program (called EC-SSI) and to verify the program’s effect on students’ EC, and “character and values.” We developed a nine-lesson program using two SSI scenarios: the Coltan mining problem and a designer baby dilemma. We collected data using questionnaires and student worksheets from 26 tenth graders and applied a mixed method approach to data gathering and analysis. We found that the program significantly improved students’ EC and “character and values.” From these results, we conclude that instructional strategies to improve students’ EC can be applied in SSI instruction and can positively affect student’s empathy and emotion regulation. We suggested that SSIs can provide an appropriate context for the improvement of students’ EC in science education and educators consider EC training integration at appropriate stages of science learning. We also recommend follow-up research to examine how students’ EC development impacts their SSI decision-making.
