CSCL环境中的社会交互

现在有很多关于计算机支持下协作学习(CSCL)异步环境中分布式学习团体(DLGs)的实证研究。研究表明当前的CSCL环境并不能完全满足人们对其支持交互的团体学习、知识共享、知识的社会建构及能力的培养的需要。在CSCL环境中,主要有两个因素阻碍我们取得预期的社会交互的成果:一是将社会交互看作是自然而然发生的,二是忽视与学习任务本身无关的社会心理交互。当前解决这个问题的办法主要是依靠教育者和教师鼓励协作学习,为了让教师从这样的负担中解脱出来,我们必须改进CSCL环境,激发和支持学习者的社会交互。     

Team regulation, regulation of social activities or co-regulation: Different labels for effective regulation of learning in CSCL

Computer-supported collaborative learning (CSCL) is an approach to learning in which learners can actively and collaboratively construct knowledge by means of interaction and joint problem solving. Regulation of learning is especially important in the domain of CSCL. Next to the regulation of task performance, the interaction between learners who work in a CSCL environment needs to be regulated as well. Despite its importance, the regulation of learning in CSCL has received relatively little attention in research. In the contributions of this special issue different labels are used for various forms of regulation of learning during CSCL. During collaborative learning, the regulation of activities can take place at different levels of social interaction: the individual level, the dyadic level, and the group level. Regulative activities of all three levels are presented in the three studies. All studies have investigated whether the use of regulative activities affected performance, and have found that regulation at the dyadic and/or group level was positively related to group performance. In sum, these three contributions provide a constructive overview of the role of regulation of the (collaborative) learning process in CSCL, both in terms of the impact of regulation on learning processes and learning results as well as the influence of different kinds of support on the regulation of collaborative learning.     

Social effects of collaborative learning in primary schools

There is conflicting evidence on whether collaborative group work leads to improved classroom relations, and if so how. A before and after design was used to measure the impact on work and play relations of a collaborative learning programme involving 575 students 9–12 years old in single- and mixed-age classes across urban and rural schools. Data were also collected on student interactions and teacher ratings of their group-work skills. Analysis of variance revealed significant gains for both types of relation. Multilevel modelling indicated that better work relations were the product of improving group skills, which offset tensions produced by transactive dialogue, and this effect fed through in turn to play relations. Although before intervention rural children were familiar with each other neither this nor age mix affected outcomes. The results suggest the social benefits of collaborative learning are a separate outcome of group work, rather than being either a pre-condition for, or a direct consequence of successful activity, but that initial training in group skills may serve to enhance these benefits.     

Investigating the Longer-Term Impact of the CREST Inquiry-Based Learning Programme on Student Self-regulated Processes and Related Motivations: Views of Students and Teachers

This study investigates the impact of participation in the CREativity in Science and Technology (CREST) programme on student self-regulated processes and related motivations. The CREST scheme, a student-run science project managed by the British Science Association, is currently being implemented in schools across the UK to increase student engagement and motivation in science. Through implementing a rigorous quasi-experimental research design using two intervention conditions and one control group with immediate as well as 3-month delayed post-test data, the results documented both the immediate and longer-term positive impact of CREST participation on students’ self-reported levels of self-regulation. The present study also investigates changes in teachers’ perceptions of students’ self-regulated learning through CREST programme participation. Group differences regarding changes in student self-reported self-regulation were not matched when looking at the teacher-reported self-regulated learning results at both immediate post-test and delayed post-test. These discrepancies are discussed in relation to analyses conducted on the other motivational constructs measured.

     

Social Aspects of CSCL Environments: A Research Framework

Although there are research findings supporting the positive effects of computer-supported collaborative learning (CSCL), problems have been reported regarding the learning process itself, group formation, and group dynamics. These problems can be traced back to impeded social interaction between group members. Social interaction is necessary (a) for group members to learn from each other in a CSCL environment and (b) for socioemotional processes to help create a social space where trust, sense of community, and strong interpersonal relationships exist. This article introduces a theoretical framework consisting of three core elements: sociability, social space, and social presence, along with their relationships with group members’ mental models, social affordances and learning outcomes. It postulates that the three core elements influence the social interaction needed for both learning and the emergence of a social space. This framework serves as a basis for a research agenda for systematic social CSCL research.

Investigating the relationship between transactive memory and performance in collaborative learning

The aim of the present study was to investigate the relationships between the three dimensions of transactive memory (coordination, credibility, and specialization) and performance of collaborating students. A total of 113 students, distributed into groups of two or three, participated in the study. They were required to complete a series of learning tasks during the semester and to write a joint report for each task to be evaluated by their instructors. Afterwards, they were asked to fill out a questionnaire including self-report measures of transactive memory. The results showed a well-established positive relationship between transactive memory and performance based essentially on coordination; also, performance improved linearly as members developed specializations within groups. Implications for future research in collaborative learning are discussed.     

The effects of guided elaboration in a CSCL programme on the learning outcomes of primary school students from Dutch and immigrant families

This study examined the effects of guided elaboration on students' learning outcomes in a computer-supported collaborative learning (CSCL) environment. The programme provided students with feedback on their elaborations, and students reflected on this feedback. It was expected that students in the experimental (elaboration) programme would show better learning gains and that students from immigrant families would especially benefit. Two hundred primary school students of 9 different schools participated. The research can be characterized as a quasi-experimental study with a pre-test, post-test, control group design. In a multilevel regression analysis, no main effect of the intervention was found. However, there was a significant differential effect of the intervention; students from immigrant families in the experimental programme outperformed their counterparts in the control group. It can be concluded that guided elaboration in a CSCL programme through feedback and reflection is a promising approach.     

Effects of gender role and task content on performance in same-gender dyads: Transactive memory as a potential mediator

This experiment was designed to examine the effects of gender role and task content on performance in learning dyads and to test the potential mediator effect of an intragroup process related to transactive memory. A total of 44 same-gender dyads participated in the study and were asked to collaborate on a stereotypically masculine or feminine task in a laboratory setting. Collective performance and transactive memory were measured. As predicted, the results showed an interaction between group gender and task content on group performance, with male dyads showing poorer performance on a masculine task than female dyads. However, contrary to expectations, this moderation effect was not mediated by transactive memory, which appeared as a simple mediator of the relationship between group gender and performance. The results are discussed in the framework of the social role theory, and implications for future research in small learning groups are proposed.     

Recognizing socially shared regulation by using the temporal sequences of online chat and logs in CSCL

The increasing amount of empirical research shows that the role of regulatory processes is critical in CSCL and collaborative learning settings. However, the current conceptual definitions and specificity of the findings vary. This is most probably because of limitations in the methods investigating regulated learning in a collaborative learning context. This study aimed to provide empirical evidence for how self- and shared regulation activities are used and whether they are useful for collaborative learning outcomes. Eighteen graduate students worked in collaborative groups for seven weeks in a CSCL course and the data of this study focuses on three one week online collaborative learning phases in the course. Temporal and sequential analysis of chat discussions and log file traces were matched to find evidence about whether the students' collaboratively planned regulatory activities became shared in practice. The results show evidence that collaborative planned regulatory activities become shared in practice. The groups that achieved good learning results used multiple regulatory processes to support their learning and also reached shared regulation. The four microlevel examples demonstrate simplified patterns of the activation of self-regulation and shared regulation. In conclusion, individual socially shared regulation plays a critical role in successful collaborative learning.     

Enhancement of self-regulation,assertiveness, and empathy

This study examined the effects of teaching self-regulation strategies and social skills to 40 middle school students in a compulsory secondary education setting, who presented difficulties in self-reflection, self-inquiry, assertiveness, and empathy. A quasi-experimental design with pre- and post-test measurements was employed. Intervention consisted of the performance of tasks, called ‘Portfolio’, related to the criteria skills during the school course. Significant differences between the experimental and the control groups were observed in the measurement of the criteria variables. Results are discussed in terms of the implications concerning how teachers can implement self-regulatory activities in their daily classroom practice to meet the educational needs of students with social problems.     

Students' perceptions of Wiki-based collaborative writing for learners of English as a foreign language

This study proposes a Wiki-based collaborative writing approach to the writing process for EFL (English as a foreign language) learners. A five-stage computer-mediated collaborative writing project including collaborative planning, partitioned drafting, peer-revising, peer-editing, and individual publishing was blended with on-campus English composition course. Fifty-one L2 learners at a university in central Taiwan participated in this project. Procedural scaffolding and collective scaffolding were provided to promote students' self-regulation and thus to foster the development of students' writing skills. A cross-referencing questionnaire survey was adopted to investigate students' perceptions of Wiki-based collaborative writing and students' perceptions of their work in each stage of collaborative writing. As the results indicated, a high percentage of students' satisfaction showed positive perceptions of this Wiki-based collaborative writing environment, and the instructional design of implementing a Wiki-based collaborative writing project with a five-stage writing process does assist EFL learners to accomplish a collaborative writing task on the internet with less limitation of time. This article also points to new possibilities for future research.     

Gender Differences in Social Mastery Motivation and Its Relationships to Vocabulary Knowledge,Behavioral Self-Regulation,and Socioemotional Skills

The present study investigated gender differences in social mastery motivation, vocabulary knowledge, behavioral self-regulation, and socioemotional skills and examined the relationships among this knowledge and these skills by gender. Participants were 134 Chinese children (68 boys, M age = 3.80; 66 girls, M age = 3.89) and their parents recruited through local kindergartens’ parent groups. The children were administered measures of social mastery motivation, vocabulary knowledge, behavioral self-regulation, and nonverbal intelligence. Parents reported their education level and children’s socioemotional skills. Research Findings: Results revealed that boys exhibited more social mastery interactions than girls, and girls showed better behavioral self-regulation and socioemotional skills than boys. Girls with higher social mastery interaction frequency demonstrated better vocabulary knowledge and socioemotional skills, whereas boys with higher social mastery interaction frequency showed lower behavioral self-regulation. Boys, who showed more positive affect during social mastery interactions, tended to have better expressive vocabulary, which facilitated their behavioral self-regulation. Practice or Policy: Findings highlight social mastery motivation as a potential factor that facilitates children’s early development, but it may contribute to boys and girls in different ways.     

跨学科协作学习何以有效——STEM教育中CSCL应用效果的元分析

STEM教育注重通过跨学科的协作学习发展学生的知识和技能。近年来,计算机支持的协作学习(CSCL)被广泛应用于STEM教育。然而,其效果如何?其采用的各类技术和教学策略对学习效果有何影响?上述问题的明确有助于完善STEM教育中跨学科的协作学习设计。基于对2009至2019年间发表在国际期刊上的142项相关实验和准实验研究成果的元分析发现:在STEM教育中应用CSCL整体上有助于提升学习效果,且相较于过程类和情感类,其对认知类学习效果的作用最为明显;从学科来看,其对科学、工程学和教育学的影响相对较大;从采用的技术来看,通信技术、动态呈现技术和共享共建技术对学习效果的影响更加显著;从教学策略来看,案例式、游戏化、知识建构和探究式等教学策略更能提升学习效果。因此,在将CSCL应用于STEM教育时,应当加强针对情感类目标的设计以激发高水平的认知活动和认知成果,注重发挥共享共建类技术在知识可视化表征、知识追踪等方面的作用,通过整合多种教学策略推进协作探究学习。     

Integrating moral and social development within middle school social studies: a social cognitive domain approach

Eleven teachers and 254 urban middle-school students comprised the sample of this study examining the social and moral development outcomes of the integration of social cognitive domain theory within regular classroom instruction. Participating teachers were trained to construct and implement history lessons that stimulated students’ moral reasoning and conceptions of societal convention. In comparison with baselines and controls, teachers reduced didactic instruction and increased the proportion of class time devoted to small group discussions. Student engagement in transactive discourse significantly increased in participating classes with significantly greater post-test levels of moral reasoning, concepts of social convention, and cross-domain coordination. Student production of operational versus representational transacts through transactive discussion was associated with growth in moral and societal concepts. Teachers continued teaching lessons constructed in the project a year after the research ended.     

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.
