The Studio curriculum in the Learning, Design, and Technology (formerly Instructional Technology) program at a large research-extensive university in the southeastern U.S. represents a deliberate application of contemporary theory of how adults learn complex information in ill-structured domains. The Studio curriculum, part of a graduate program leading to a master’s degree, has been implemented since 1998 to prepare professionals to design, develop, evaluate, and manage educational multimedia. Theoretical considerations played a major role in shaping the design of the Studio curriculum. Prominent among these were constructionism, situated cognition/situated learning, and self-directed learning. Important related theoretical constructs included scaffolding and flow theory. This paper describes the Studio learning environment, presents these theoretical concepts, and discusses the application of theory to practice in the training of adults in instructional design and development (IDD). 相似文献

Reading has been regarded as a medium for learning science, revealing the importance of enhancing learners’ reading competence in science education. The critical features of science texts are their multiple representations, such as text and visual elements, which assist the representation of science concepts. A multimedia learning environment can present relevant materials in various formats and help students to process the materials in meaningful ways, for example, by integrating learning materials with relevant prior concepts, and organizing them into a consistent and coherent cognitive structure. However, some issues with multimedia instructional design have been proposed, such as students’ cognitive load and learning motivations. In this study, an augmented reality-based science learning system was developed based on the contiguity principle of multimedia learning in order to promote students’ science learning. Moreover, an experiment was conducted on a natural science course in an elementary school to assess the effectiveness of the implemented system on students’ learning. The experimental results display that the students learning with this approach found made significant gains in their learning achievements and motivations compared to those learning science with conventional multimedia science learning; moreover, their perceptions of extraneous cognitive load were significantly reduced during the learning activity. 相似文献

In this paper, we propose a theoretical framework for designing on-line situated assessment tools for multimedia instructional systems. Based on an ecological psychology approach to situated learning, a graph theoretic methodology is applied to monitor students' performance (solution paths) throughout the learning activity. Deviation of the student's path from the target (expert) path generates indicators which can function as alerts to the student and to the instructor. The information collected in the dribble files and presented visually enables the instructor to identify problems quickly and intervene appropriately. The feasibility of the methodology is explored in case studies describing three instructional systems that teach (1) critical thinking and problem-solving skills, (2) principles of hemodynamic monitoring and treatment, and (3) orthodontic treatment, respectively. 相似文献

多媒体学习理论是一个贯通了学习理论与教学理论的科学体系。作为学习理论的多媒体学习认知理论基于双重编码理论、工作记忆模型以及生成加工理论,解释了学习者通过加工语词与画面所呈现的材料来建构知识的学习机制,属于解释性理论;作为教学理论的多媒体教学设计理论发展出一系列教学设计应遵循的原则,为教育实践提供了具有处方性意义的行动指南,属于处方性理论。解释性的学习理论为处方性的教学理论提供了扎实可靠的科学基础。在多媒体学习研究从学习理论向教学理论转化的过程中,多媒体教学设计理论是实现跃迁的关键环节,而认知负荷理论则是理论跃迁成功的关键变量。基于认知负荷理论,梅耶提出多媒体学习认知负荷三元模型,包括必要认知加工、外来认知加工和生成性认知加工。围绕这三类认知加工,梅耶及其同事进行了大量的实验研究,最终确定了12项与多媒体学习认知理论及其前提假设保持高度逻辑一贯性的多媒体教学设计原则。这些原则都是经得起实践检验的,但教学设计人员在应用的过程中,应明确各项原则的问题情境、适用范围等边际条件。 相似文献

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains. 相似文献

Although explanations are a common means of instruction, research shows that they often do not contribute to learning. To unravel the factors giving rise to the ineffectiveness of instructional explanations, we propose a framework that brings together empirical work on instructional explanations from a variety of research fields, including classroom instruction, tutoring, cooperative learning, cognitive skill acquisition, learning from texts, computer-supported learning, and multimedia learning. In our framework, we identify the distinctive characteristics of instructional explanations, present general guidelines for designing instructional explanations, and describe factors influencing both the generation and use of instructional explanations. It is argued that future research should uncover in more detail the interrelations between the different aspects of providing and using instructional explanations and their specific effects on learning. 相似文献

Evidence of the value of constructivist theory in the classroom is especially important for educational practice in areas of poverty and social challenge. Research was undertaken in 2010 into the application of constructivist theory on instructional design. The findings of this research are particularly relevant to the current curricular crisis in South Africa which threatens to side-line constructivist priorities and return learners to rote learning from textbooks. The findings are situated here within the national debate over curricular design and instructional models. Placing instructional design within the larger context of national pedagogical contestation provides important evidence of the central role of Freirean imperatives for South Africa’s educational future. This article indicates that a constructivist framework, when pertinently arranged, provides holistic and sustainable procedures for knowledge creation. The findings from the research project showed that, in an environment conducive to learning, learners become self-motivated and better able to master the next phase of the curriculum. As a result of the constructivist framing, participants grew into strategic and effective learners who took responsibility for their own learning. These findings add weight to the call for reconsideration of constructivist foundations in national curriculum design. 相似文献

The purpose of this article is to describe the development, validation and use of the Constructivist Multimedia Learning Environment Survey (CMLES). This questionnaire assesses teachers' and students' perceptions of the learning environment when students use online
multimedia programs while teachers use constructivism as a referent for their teaching. The design of the questionnaire was
based on a constructivist approach to learning and focused on the process of learning with the multimedia program and on the
nature of that program. Before the use of the CMLES becomes widespread, it was important to determine whether it is valid
and reliable. Therefore, a study involving 221 students in 12 high school classrooms into statistical validation and interpretive
validation of the questionnaire was undertaken. For this sample of Grade 10 and 11 students who completed the actual and preferred
forms of the questionnaire, the CMLES scales demonstrated a high degree of internal consistency reliability (with alpha reliability
coefficients ranging from .73 to .82), as well as satisfactory factorial validity and discriminant validity. Therefore, the
study supports the reliability and validity of the CMLES for assessing students' and teachers' perceptions of one important
aspect in evaluating learning environments which promote the use of multimedia programs and constructivist learning approaches. 相似文献

This qualitative study investigated a situated learning environment implemented in an educational technology course where pre-service teachers worked collaboratively on meaningful real-world projects, assuming the role of professional teachers. With a traditional learning environment as a critical frame of reference, we found that the students in the situated learning environment demonstrated sophisticated problem-solving skills, exhibited metacognitive awareness, produced coherent artifacts, and showed high levels of motivation. The findings implied that if we want to successfully implement situated learning, effort should be made to promote a constructive learning culture, improve individual performance, manage students’ perceptions, and foster their positive attitudes. 相似文献

This usability study evaluated users' perceptions of a multimedia prototype for a new e‐learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e‐learning tools to maximize user acceptance, satisfaction, and adoption. Sixty‐two study participants piloted the prototype and completed a usability questionnaire designed to measure two usability properties: program need and program applicability. Statistical analyses were used to test the hypothesis that the multimedia prototype was well designed and highly usable, it was perceived as: (1) highly needed across a spectrum of educational contexts, (2) highly applicable in supporting the pedagogical processes of teaching and learning neuroanatomy, and (3) was highly usable by all types of users. Three independent variables represented user differences: level of expertise (faculty vs. student), age, and gender. Analysis of the results supports the research hypotheses that the prototype was designed well for different types of users in various educational contexts and for supporting the pedagogy of neuroanatomy. In addition, the results suggest that the multimedia program will be most useful as a neuroanatomy review tool for health‐professions students preparing for licensing or board exams. This study demonstrates the importance of integrating quality properties of usability with principles of human learning during the instructional design process for multimedia products.

Distance education has long been associated with independent study and delivery of prepackaged learning materials. These characteristics effectively deny distance education students the opportunity to participate in communities of inquiry and, perhaps, opportunities to develop their critical thinking skills. This paper reviews the theoretical impact of socially situated learning, critical thinking and their implications for distance education. It then presents the results from a study of learners' perception while enrolled in two different models of audio teleconferenced, university courses. The study reports quantitative results from a mail survey of these students and the qualitative results from interviews and classroom observations. The impact of the instructional design used by the delivering institution resulted in two distinct models of audio teleconference delivery with significant qualitative and quantitative differences in student perception. The paper concludes that learning communities, which support the development of critical thinking skills, can be created at a distance and that they provide a mechanism for improving the quality of higher level distance education. 相似文献

Using schema theory as a framework, we view learning as an active, constructive process. It is affected not only by learners' internal knowledge structures, but by the external constraints of the learning environment as well (Kozma, 1991). This article examines how different internal learner characteristics (e.g., prior knowledge, self efficacy and interest) and different external constraints (e.g., learner control, instructional design and level of control) influence the learning process. Specifically, we address learning from a variety of multimedia environments such as video, hypertexts, kiosks and other hypermedia within a schema theoretic approach that incorporates a constructivist view. 相似文献

A Teacher Professional Development Program on Using a Constructivist Multimedia Learning Environment
This paper describes a professional development program using an interactive multimedia program to develop teachers' understanding
of a constructivist epistemology in science education. The aim of this study was to describe teachers' reflections on and
perceptions of a series of professional development workshops and how teachers changed their classroom practices after having
participated in the workshops. The software, developed with the cooperation of teachers and students, is based on the Birds of Antarctica database (Maor & Phillips, 1996). This database was designed as an interactive program which requires teachers to use a constructivist-oriented
approach to teaching and learning in order to promote the development of inquiry skills particularly higher-order thinking
skills. A series of workshops for teachers was conducted to empower them to become comfortable with using computers in science
classrooms and to enable them to enhance their understanding of, and ability to use, personal and social constructivist approaches.
Teachers' perceptions of the process of learning with the multimedia program and their reactions to their experiences were
assessed using a new instrument, the Constructivist Multimedia Learning Environment Survey (CMLES). The results of the study suggest that teachers who participated as learners in the professional development program
became familiar with a constructivist-oriented multimedia learning environment; understood the context, problems, and issues
faced by students in the classroom; and were better able to facilitate students' needs and understanding in this learning
environment.

A major challenge for learning theories is to illuminate how particular kinds of learning experiences and environments promote
the development of expertise. Research has been conducted into novice-expert differences in various domains, but few studies
have examined the processes involved in learners’ expertise development. In an attempt to understand the development of expertise
in instructional design (ID) among graduate students, this study aimed to investigate (1) the patterns of expertise development
among ID learners over an extended period; (2) the roles of expert modelling, peer feedback, self-reflection and participation
in a supportive learning community in learners’ expertise development; and (3) the interactions of individual differences
and the learning environment in learners’ expertise development. A qualitative design was used to investigate students’ expertise
development across a range of dimensions. The participants were two cohorts of 11 graduate students in a program on instructional
psychology and design. Data, including observations, interviews, design documents, metacognitive essays and peer feedback,
were collected for triangulation and in-depth analysis. The results showed that the two cohorts exhibited similar patterns
in their ID expertise development. These development processes were influenced by both self-processes and social influences.
Self-processes are determined by the perceptions, motivation and prior knowledge that students bring into the learning environment.
Social influences are characterised by a learning community that encourages peer interactions and feedback and is supported
by expert modelling and scaffolding. 相似文献

梅耶的多媒体学习理论是建立在坚实的理论基础和可靠的实证经验基础上的科学体系。多媒体学习的认知理论是理解多媒体学习的关键。双重通道假设、容量有限假设和主动加工假设是梅耶构建多媒体学习认知理论的基石,也是整个多媒体学习科学体系的逻辑起点。这三大假设赖以成立的理论前提正是双重编码理论、工作记忆模型、生成学习理论和认知负荷理论,由此构成了多媒体学习的理论基础。具体而言,双重编码理论和工作记忆模型为多媒体学习的认知理论构建提供了关键概念与元素;生成学习理论则为多媒体学习的认知理论构建提供了基本的解释性框架;多媒体学习的认知理论正是由这些关键概念、元素和解释性框架整合而成;而认知负荷理论则以多媒体学习的认知理论为基础,进而为多媒体教学的系列设计原理提供了关键支撑。 相似文献

Recently, multimedia-based learning is widespread in educational settings. A number of studies investigate how to develop effective techniques to manage a huge volume of video sources, such as summarization and recommendation. However, few studies examine how these techniques affect learners' perceptions in multimedia learning systems. This article aims to examine learners' perceptions for summarization and recommendation, with an emphasis on the perspective of prior experience. In this study, we developed a multimedia content summarization and recommendation system, which can automatically extract summaries from raw video sources and recommend suitable video content to learners through emails. The results demonstrate that learners' prior experience and preferences for the presentation of document types affect their perceptions, including the enhancement of interests, the ease of information acquisition and the intention for the further use of the system. Finally, the findings are applied to develop a framework that can support for the design of multimedia learning systems. 相似文献

Perceptions of instructional quality: impact on acceptance and use of an online learning environment
ABSTRACTGiven the growing use of online learning environments in higher education, it is important to further unravel how students’ use is influenced by their perceptions towards these learning environments. This study includes the perceived quality of the instructional design based on the First Principles of Instruction of Merrill and students’ acceptance based on the constructs perceived usefulness and perceived ease of use of the technology acceptance model (TAM). The aim of this study is twofold: a first aim is to investigate the influence of the perceived instructional quality on students’ acceptance and the second aim is to investigate the impact of students’ acceptance and the perceived instructional quality on the quantity (i.e. course activity) and quality (i.e. course performance) of use. In this study, a Moodle-based online learning environment for learning French as a foreign language was studied. Participants were 161 university students. Structural equation modeling (SEM) indicates that the perceived instructional quality has a significant positive influence on students’ acceptance. Furthermore, students’ perceived instructional quality has a positive influence on the quality, but not on the quantity of use, whereas students’ acceptance of the online learning environment has no impact on the use of the learning environment. 相似文献

Based on a critical re-analysis of cognitive load theory (CLT), Schnotz and Kürschner identified the need for research on more sensitive ways of assessing learner characteristics, both prior to and during instruction, in order to understand learning processes and outcomes. One emergent theme of the papers in this special issue is that the “same” learning environment is differentially demanding and produces different results depending on characteristics of the learners, most importantly their knowledge in the task domain. These findings indicate that to optimize learning outcomes, theories of instructional design and learning need to be more adaptive and reflect the nuances of interactions among learners, tasks, and instructional supports. 相似文献
