Implementing collaborative learning activities in the classroom supported by one-to-one mobile computing: A design-based process

Mobile devices such as PDAs, smartphones and tablet computers are becoming increasingly popular, setting out opportunities for new ways of communicating and collaborating. Research initiatives have ascertained the potential of mobile devices in education, and particularly, the benefits of incorporating them in the classroom for eliciting collaborative learning and active student participation. However, the development of technology-supported learning environments poses challenges to education researchers, practitioners, and software technologists in creating educational tools that respond to real needs of instructors and learners, meet clearly defined didactic purposes, and are practical for the intended audience. This article reports on a technology for facilitating the implementation of collaborative learning environments in the classroom supported by one-to-one mobile computing. The approach encompasses a framework supporting the design and implementation of the mobile software, and a design-based process that guides interdisciplinary efforts utilizing the framework, towards creating effective pedagogical models based on collaborative learning. The proposed design-based process allowed us to develop pedagogical models that respond to real needs of learners and instructors, where development is grounded on rigorous scientific research, allowing to reuse both knowledge and software, and showing an improvement of the mobile software built based on continuous experimentation and evaluation. A case study illustrating the application of the technology is presented and plans for future research are discussed.     

The development of a cognitive tool for teaching and learning fractions in the mathematics classroom: A design-based study

Two cycles of design-based research of a cognitive tool (CT) for teaching fractions have been completed. Following the success of a quasi-experimental study of the enhanced CT derived from the second cycle of design-based research, this article reports the findings of a pre-test–post-test control group empirical study using the enhanced CT in the classroom. The results indicate that there were no statistically significant differences in learning outcomes between the exploratory learning approach, using the CT, and the traditional direct teaching approach. The CT enabled students to generate a procedural knowledge of adding and subtracting fractions with like and unlike denominators through an exploratory learning process. Teachers asserted that the CT was effective for stimulating reciprocal tutoring among students, and students were enthusiastic about using the CT as an educational tool. Hence, the CT has potential for further development as a tool for promoting collaborative learning in the classroom.     

Interaction between tool and talk: how instruction and tools support consensus building in collaborative inquiry-learning environments

The process of collaborative inquiry learning requires maintaining a mutual understanding of the task, along with reaching consensus on strategies, plans and domain knowledge. In this study, we explore how different supportive measures affect students' consensus-building process, based on a re-analysis of data from four studies. We distinguish between scaffolds that aim at supporting students' collaborative processes and scaffolds that aim primarily at supporting the inquiry learning process. The overall picture that emerges from the re-analysis is that integration-oriented consensus-building activities are facilitated by scaffolds that provide explicit instruction in rules for effective collaboration and by scaffolds that encourage students to collaboratively construct a representation. Scaffolds that display inter-individual differences between students' opinions resulted primarily in quick consensus-building activities.     

Teacher interventions in a synchronous,co-located CSCL setting: Analyzing focus,means, and temporality

Computer-supported collaborative learning (CSCL) environments facilitate collaboration between students. There is a growing interest in studying the role of the teacher during CSCL. This study aims to contribute to the conceptualization of teacher interventions during CSCL. A teacher and his class worked in a CSCL environment for 8 lessons. Focus and means of teacher interventions were analyzed across these 8 time points. The results show that the teacher’s behavior varied greatly between lessons and also between groups, which contradicts research that has aggregated teacher behavior to types or teaching styles. Findings consistent across time points include the predominance of the teacher’s focus on students’ cognitive rather than social activities, and a higher number of interventions in groups where student activity was higher. Suggestions are made for future research, which include studying the effectiveness of supporting tools for teachers.     

Roles as a structuring tool in online discussion groups: The differential impact of different roles on social knowledge construction

This study focuses on stimulating social knowledge construction in e-discussions and examines the introduction of five roles: starter, summariser, moderator, theoretician, and source searcher. Asynchronous discussion groups of 10 1st-year students Instructional Sciences were organised to foster students’ processing of the learning content. Four successive authentic tasks of three weeks each were presented. Taking into account the moment of introduction of the role assignment (at the start of the discussions versus at the end), the differential impact of the roles on knowledge construction is studied through quantitative content analysis based on the interaction analysis model of Gunawardena, Lowe, and Anderson (1997). The results show a positive effect of role assignment on students’ social knowledge construction at the start of the discussions. This implies that roles should be introduced at the start of the discussions and can be faded out towards the end. With respect to the differential impact of the roles, the results show that messages from moderators, theoreticians, and summarisers reflect higher levels of knowledge construction at the start of the discussions. Even students without a role in role-supported groups benefit from the role introduction.     

Wiki as a collaborative writing tool in teacher education: Evaluation and suggestions for effective use

Wiki technology provides new opportunities to foster collaborative writing in teacher education. To empirically evaluate the level of collaborative writing in a wiki-based environment, this article used three methods and their combination. The first method was the history function that records all students’ actions, enabling to trace all changes made in the wikis. The actions were analyzed in terms of number and percentage of contribution using a taxonomy categorized by 10 editorial types. The second method examined comments posted on the wiki discussion page to evaluate the level of collaboration. The third method provided feedback on the level of collaboration by means of peer assessment. The results show important differences in the types of contributions across the categories investigated. The results also reveal that the level of collaborative writing was lower than expected. Possible factors that may influence wiki-based collaborative writing are discussed. Finally, suggestions for effective use of wikis as collaborative writing tools in teacher education conclude the article.     

From pattern to practice: Evaluation of a design pattern fostering trust in virtual teams

This article describes the implementation and evaluation of a design pattern that fosters trust in mediated collaborative settings. The pattern proposed here should provide a profile with static and/or dynamic information about the participants of a collaborative environment. It aims to foster initial (in the first two to three weeks) trust in situations in which people do not know each other and do not have a chance to meet, but need to collaborate. A simple and low cost implementation of this pattern was realized by conducting a case study with participants of the European Virtual Seminar on Sustainable Development (EVS). They were asked to fill in a template with personal information about themselves. In the EVS, students collaboratively have to address sustainable development problems. Afterwards, students were questioned on the use of this template, called PEXPI, and their impressions of each other during and after the EVS; questionnaires and a semi-structured interview were used. The results show that the implementation of the static profile, derived from the pattern, initially helped students to form an impression of each other. After this initial period, however, students base their impression on factors such as the quality of work-related contributions, behaviour during collaboration (e.g. responsiveness), and communication style. This case study also shows that the pattern could easily be applied and transferred to a new context, as long as the conditions described in the ‘context’-section of the pattern, were met. The case study provided a means for evaluation of the pattern and a source for its refinement.
