This study investigates the mechanisms of scaffolding in a synchronous network-based environment – the ‘collaborative virtual
workplace’. A theoretical ‘multi-actor’ scaffolding model was formulated. The study itself focused on the role and inter-relations
of verbal scaffolding by tutor and peers during a collaborative process of making decisions about environmental issues. The analysis drew on data from the decision-making
discussions of 31 groups – material that was saved automatically by the learning environment software. The age of the 62 students
ranged from 14 to 17. Discourse act categories were devised to describe the tutor’s and the students’ task-related, supportive
and social communicative acts. The scaffolding situation was characterized through a causal discourse act interaction approach.
Tutor and students appeared to be elaborating and replacing each other’s process scaffolding acts in the collaborative decision-making
situation. The influence of certain tutor’s and students’ inter-related scaffolding patterns on students’ decision-making
provided empirical support for the ‘multi-actor’ scaffolding model.

Round or rectangular tables for collaborative problem solving? A multimodal learning analytics study
Milica Vujovic Davinia Hernández-Leo Simone Tassani Daniel Spikol 《British journal of educational technology : journal of the Council for Educational Technology》2020,51(5):1597-1614
The current knowledge of the effects of the physical environment on learners’ behaviour in collaborative problem-solving tasks is underexplored. This paper aims to critically examine the potential of multimodal learning analytics, using new data sets, in studying how the shapes of shared tables affect the learners’ behaviour when collaborating in terms of patterns of participation and indicators related to physical social interactions. The research presented in this paper investigates this question considering the potential interplay with contextual aspects (level of education) and learning design decisions (group size). Three dependent variables (distance between students, range of movement and level of participation) are tested using quantitative and qualitative analyses of data collected using a motion capture system and video recordings. Results show that the use of round tables (vs rectangular tables) leads to higher levels of on-task participation in the case of elementary school students. For university students, different table shapes seem to have a limited impact on their levels of participation in collaborative problem solving. The analysis shows significant differences regarding the relationship between group size and the distance between students, but there is no substantial evidence that group size affects the level of participation. The findings support previous research highlighting the importance of studying the role of the physical environment as an element of learning design and the potential of multimodal learning analytics in approaching these studies. 相似文献

There has been wide recognition that today’s graduates need the type of generic capabilities necessary for lifelong learning.
However, the mechanism by which universities can develop these generic skills is not clearly established. This study aimed
to investigate the mechanism for their development. Structural equation modeling (SEM) was used to test a hypothesized model
of capability development through a suitable learning environment with 1756 undergraduates at a university in Hong Kong. To
triangulate against this model and more fully characterize the learning environment, focus group interviews were held with
five to six students from three programs with good records of capability development. Analysis of the interview data resulted
in a set of categories, describing a learning environment, which were consistent with the SEM model. The learning environment
which seemed conducive to capability development aimed for understanding of key concepts through a variety of assessment methods
and active engagement in learning activities. Teacher–student relationships were developed through interaction, feedback and
assistance. The promotion of peer–student relationships led to a high degree of collaborative learning. 相似文献

This study examines the effectiveness of three scaffolding conditions on adolescents’ learning about the circulatory system
with a hypermedia learning environment. One hundred and eleven adolescents (n = 111) were randomly assigned to one of three scaffolding conditions (adaptive scaffolding (AS), fixed scaffolding (FS),
or no scaffolding (NS)) and were trained to use a hypermedia environment to learn about the circulatory system. Pretest and
posttest data were collected to measure the qualitative changes in students’ mental models of the topic and quantitative changes
in their declarative knowledge. Verbal protocols were collected during the 40-minute learning task to examine how each condition
affected the way in which students regulated their learning. Findings revealed that learners in both the AS and NS conditions
gained significantly more declarative knowledge than did those in the FS condition. Also, the AS condition was associated
with shift in learners’ mental models significantly more than the other conditions. Associated with these significant shifts
in their mental models, learners in the AS condition regulated their learning by planning and activating prior knowledge,
monitoring their cognitive activities and their progress toward learning goals, using several effective strategies, and engaging
in adaptive help-seeking. By contrast, those in the NS condition used fewer effective strategies, while those in the FS regulated
their learning by using several regulatory processes which seemed to impede their learning. Implications for the design of
scaffolds for fostering students’ self-regulated learning with hypermedia are presented. 相似文献

We present a study on the effect of instruction on collaboration in a collaborative discovery learning environment. The instruction
we used, called RIDE, is built upon four principles identified in the literature on collaborative processes: Respect, Intelligent collaboration, Deciding together, and Encouraging. In an experimental study, a group of learners (ages 15–17) receiving this instruction was compared to a control group. The
learners worked in dyads on separate computers in a shared discovery learning environment in the physics domain of collisions,
communicating through a chat channel. Qualitative and quantitative analyses of the logged actions in the learning environment
and the chat protocols showed that the RIDE instruction can lead to more constructive communication, and improved discovery
learning activities, as expected, although no direct effect on discovery learning results was found. This study shows the
benefits of providing instruction on effective communication and the learning process in a collaborative discovery learning
situation. 相似文献

Prior research has shown that tutored problem solving with intelligent software tutors is an effective instructional method,
and that worked examples are an effective complement to this kind of tutored problem solving. The work on the expertise reversal
effect suggests that it is desirable to tailor the fading of worked examples to individual students’ growing expertise levels.
One lab and one classroom experiment were conducted to investigate whether adaptively fading worked examples in a tutored
problem-solving environment can lead to higher learning gains. Both studies compared a standard Cognitive Tutor with two example-enhanced
versions, in which the fading of worked examples occurred either in a fixed manner or in a manner adaptive to individual students’
understanding of the examples. Both experiments provide evidence of improved learning results from adaptive fading over fixed
fading over problem solving. We discuss how to further optimize the fading procedure matching each individual student’s changing
knowledge level. 相似文献

This article analyzes the collaborative problem solving activities and learning outcomes of five groups that worked on two different complex cases in a virtual professional training course. In this asynchronous virtual learning environment, all knowledge management content was delivered virtually and collaboration took place through forums. To measure the effects of the problem solving activities, learners' contributions were analyzed with respect to four different problem solving activities: Two content-specific problem solving activities, namely gathering information and developing a solution, and two coordination-specific problem solving activities, namely planning the common approach and steering the interaction process. Results indicated that the learning process was dominated by two central activities: developing a solution and steering the interaction process. Furthermore, the results indicated that the groups with the more complex case used more overall problem solving activities than the groups with the less complex case. There was also a greater range of learning outcomes for learners with the more complex case than for learners with the less complex case. Finally, the number of overall problem solving activities for most of the successful groups was higher than for the less successful groups. Additionally, the more successful groups used more coordination-specific activities than content-specific activities during the problem solving process. 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.

Group formation task as a starting point for computer-supported collaborative learning plays a key role in achieving pedagogical goals. Various approaches have been reported in the literature to address this problem, but none have offered an optimal solution. In this research, an online learning environment was modeled as a weighted undirected complete graph in which each learner was implied as a node and the relationship between them was denoted as a weighted arc. The weight of each link indicated the similarity degree between the corresponding individuals. The similarity between two students was measured as the mean of their absolute interest levels. The graph was also represented through a symmetric adjacency matrix. Then, a novel binary integer programming formulation was proposed to model the group formation problem and optimally assign each learner to the most appropriate group. The method was utilized to divide an online class of 32 learners into 8 groups of size 4. Findings indicated that the suggested model was successful in optimally solving the problem in 20.53 seconds, on average. The performance of the method was also compared with a modified version of K-means clustering algorithm. Although, the running time of the suggested technique was not as good as the clustering algorithm, it generated better outcomes in theory and in practice. 相似文献

In the 21st century when knowledge-based economy is emphasized, the cultivation of autonomous learning and problem-solving abilities presents the importance. With web-based collaborative problem-based learning (CPBL), learners could more conveniently cultivate their problem-solving abilities through autonomous learning. Nevertheless, learners are often guided to solve a target problem by the information announced by teachers during the CPBL processes. Individual learners often could not effectively absorb such standard information, thus ignoring the important information from teachers. In the information communication theory, the two-step flow of communication through opinion leaders has been proved that it can better change audiences’ attitudes than the one-step flow of communication through mass media. This study thus employs the modularity Q function as the fitness function of genetic algorithm to optimally detect learning communities and uses PageRank measure to accurately find out community opinion leaders according to the social network interaction data of learners in the CPBL process. Based on quasi-experimental design, this study examines whether learners in the experimental group using the two-step flow of communication through opinion leaders to convey information for solving the target CPBL missions could more significantly enhance web-based CPBL performance, social network interaction and group cohesion than learners in the control group using the one-step flow of communication through teachers’ information. Analytical results show learners in the experimental group remarkably outperform those in the control group on learning performance and peer interaction under a CPBL environment. Particularly, female learners in the experimental group notably outperform female learners in the control group on learning performance, while there is no significant difference in male learners between both groups. More importantly, learners in the experimental group present significantly higher group cohesion than those in the control group. This study confirms that using the two-step flow of communication instead of the one-step flow of communication traditionally used in web-based learning environments could significantly promote web-based CPBL performance, social network interaction and group cohesion. 相似文献

This article examines the role elementary school children’s spontaneous metaphors play in learning science. The data consists
of tape recordings of about 25 h from five different schools. The material is analysed using a practical epistemology analysis
and by using Dewey’s ideas on the continuity and transformation of experience. The results show the rich and varied meanings
that children put into their spontaneous metaphors. Their metaphors deal with facts as well as norms and aesthetics in relation
to the science content taught and they influence learning both through what is made salient, as well as through their relations
to the children’s possibilities of proceeding with their undertakings. Often one and the same metaphor encompassed all these
cognitive, aesthetic and normative aspects at the same time. It is discussed how this rich meaning can be cultured in a productive
way, and how the children’s spontaneous metaphors, with all their relations, can be used to enhance conceptual learning and
also learning about the nature of metaphor use in science. Through their connection with various experiences of the children,
it is also shown how children’s spontaneous metaphors have the potential to enliven and humanise the subject. 相似文献

This article applies the concept of classroom community to asynchronous learning networks (ALNs) by taking on the issue of how best to design and implement a course that fosters community among learners who are physically separated from each other. The following factors that can influence sense of community among distant learners are examined: student–instructor ratio, transactional distance, social presence and instructor immediacy, lurking, social equality, collaborative learning, group facilitation, and self-directed learning. 相似文献

AbstractThis article reports on a study that examined teaching and learning in multi-grade classrooms using the Learning Environment, Learning Processes and Learning Outcomes (LEPO) conceptual framework. The study sought to investigate how the learning environment is created; how the processes of teaching and learning take place; and how assessment is used to determine the achievement of learning outcomes in multi-grade classrooms. A qualitative research design was used, where interviews were conducted with nine teachers from schools with multi-grade classrooms. The data was analysed thematically and revealed the following: the learning environment can be created by grouping learners appropriately in classrooms, creating learning stations and reading stations, proper use of time-tables, and adaptation of teaching plans; the learning processes should take place through the differentiated curricular approach or quasi mono-grade, that is, learners should be afforded the opportunity to learn from their family members, teaching and learning should take place through self-directed learning, peer tutoring and cooperative learning, and lessons should cater for different learning styles; to determine the realisation of learning outcomes teachers should assess learners in different grades informally with either the same or grade-specific assessment activities and formally with grade-specific assessment tasks. The article also addresses the main criticisms against the LEPO framework by explaining how teachers and learners should interact with the learning environment, learning processes and learning outcomes in multi-grade classrooms. The article concludes that if the LEPO framework can be implemented in multi-grade classrooms, teaching and learning can be strengthened in such classrooms. 相似文献

Metacognition, Self Regulation, and Self-regulated Learning: A Rose by any other Name? 总被引：1，自引：1，他引：0
Susanne P. Lajoie 《Educational Psychology Review》2008,20(4):469-475
This commentary reviews the distinctions researchers make in defining metacognition, self-regulation, and self-regulated learning
along with the methods used to explore these constructs. Bandura’s notion of reciprocal determinism (1977) is revisited in the context of situated learning, whereby interactions between the person, behavior, and environment take
on new meaning when examining learning and affect in specific contexts where knowledge is constructed through interacting
with all that the environment affords, be that material or human. The interaction between the mind and environment continues
to be an interesting question with regard to these three constructs, and this interaction can be explored by using computers
as cognitive tools. Technology-rich environments are described that provide opportunities for assessing and validating metacognition,
self-regulation, and self-regulated learning with future directions for assessing co-regulation of teams of learners. 相似文献

This article is a result of a completed survey of the mainly cognitive science literature on the transferability of those
skills which have been described variously as ‘core’, ‘key’, and ‘generic’. The literature reveals that those predominantly
cognitive skills which have been studied thoroughly (mainly problem solving) are transferable under certain conditions. These
conditions relate particularly to the methods and environment of the learning of these skills. Therefore, there are many implications
for the teaching of key skills in higher education, which the article draws out, following a summary of the main findings
of the research literature. Learning of principles and concepts facilitates transfer to dissimilar problems, as it creates
more flexible mental representations, whereas rote learning of facts discourages transfer. Transfer is fostered when general
principles of reasoning are taught together with self-monitoring practices and potential applications in varied contexts.
Training in reasoning and critical thinking is only effective for transfer, when abstract principles and rules are coupled
with examples. Transfer is promoted when learning takes place in a social context, which fosters generation of principles
and explanations. Transfer improves when learning is through co-operative methods, and where there is feedback on performance
with training examples. The specificity of the context in which principles are learned reduces their transfer. Transfer is
promoted if learners are shown how problems resemble each other, if they are expected to learn to do this themselves, if they
are aware of how to apply skills in different contexts, if attention is directed to the underlying goal structure of comparable
problems, if examples are varied and are accompanied by rules or principles (especially if discovered by the learners), and
if learners’ self-explanations are stimulated. Learning to use meta-cognitive strategies is especially important for transfer. 相似文献

Learning from Learning Kits: gStudy Traces of Students’ Self-Regulated Engagements with Computerized Content 总被引：4，自引：0，他引：4
Researching self-regulated learning (SRL) as a process that evolves across multiple episodes of studying poses large methodological challenges. While self-report data provide useful information about learners’ perceptions of learning, these data are not reliable indicators of studying tactics learners actually use while studying, especially when learners are young children. We argue that self-reports about SRL need to be augmented by fine-grained traces that are records of learners’ actual activities as they study. We describe how gStudy software unobtrusively collects detailed trace data about learners’ use of study tactics as they engage with content presented in learning kits—collections of documents (e.g., texts, graphics, video clips) and tasks (e.g., notes, concept maps) on which learners operate to study. We suggest that trace data can advance research about how learners select, monitor, assemble, rehearse, and translate information to learn it, and provide raw materials for mapping SRL and its effects. Examples from the Life Cycles Learning Kit that supports grade 1 students learning about the life cycles of humans and frogs are given.
