Knowledge convergence in computer-supported collaborative learning

This study investigates how two types of graphical representation tools influence the way in which learners use knowledge resources in two different collaboration conditions. In addition, the study explores the extent to which learners share knowledge with respect to individual outcomes under these different conditions. The study also analyzes the relationship between the use of knowledge resources and different types of knowledge. The type of external representation (content-specific vs. content-independent) and the collaboration condition (videoconferencing vs. face-to-face) were varied. Sixty-four (64) university students participated in the study. Results showed that learning partners converged strongly with respect to their use of resources during the collaboration process. Convergence with respect to outcomes was rather low, but relatively higher for application-oriented knowledge than for factual knowledge. With content-specific external representation, learners used more appropriate knowledge resources without sharing more knowledge after collaboration. Learners in the computer-mediated collaboration used a wider range of resources. Moreover, in exploratory qualitative and quantitative analyses, the study found evidence for a relation between aspects of the collaborative process and knowledge convergence

A web-oriented framework for the development and deployment of academic facing administrative tools and services

The demand for higher education has increased dramatically in the last decade. At the same time, institutions have faced continual pressure to reduce costs and increase quality of education, while delivering that education to greater numbers of students. The introduction of software systems such as virtual learning environments, online learning resources and centralised student record systems has become routine in attempts to address these demands. However, these approaches suffer from a variety of limitations: They do not take all stakeholders’ needs into account. They do not seek to reduce administrative overheads in academic processes. They do not reflect institution-specific academic policies. They do not integrate readily with other information systems. They are not capable of adequately modelling the complex authorisation roles and organisational structure of a real institution. They are not well suited to rapidly changing policies and requirements. Their implementation is not informed by sound software engineering practises or data architecture design. Crucially, as a consequence of these drawbacks such systems can increase administrative workload for academic staff. This thesis describes the research, development and deployment of a system which seeks to address these limitations, the Module Management System (MMS). MMS is a collaborative web application targeted at streamlining and minimising administrative tasks. MMS encapsulates a number of user-facing tools for tasks including coursework submission and marking, tutorial attendance tracking, exam mark recording and final grade calculation. These tools are supported by a framework which acts as a form of “university operating system”. This framework provides a number of different services including an institution abstraction layer, role-based views and privileges, security policy support integration with external systems

A Learning Community Approach for Post-Secondary Large Lecture Courses

This design-based research (DBR) study examined the ways in which a learning community approach can be enacted in large undergraduate lecture courses through a scaffolded, complex curricular design that utilizes active and inquiry-based learning. By combining a traditional lecture with breakout tutorials, the study involved two iterations, firstly by adopting the Fostering Communities of Learners (FCL) pedagogical model, then by augmenting the model by blending its methodology with elements from a more recent model called Knowledge Community and Inquiry (KCI). Both iterations were evaluated for adherence to, and enactment of, the FCL principles. The second iteration was further evaluated to determine the impact of adding a KCI collective knowledge base. Measures included the enactment of the curricular design, achievement of course learning outcomes, the group inquiry project, tutorial activities, and focus groups for teaching assistants and students. Findings provided evidence of the viability and effectiveness of a learning community approach in large lecture courses at the undergraduate level when combining the learning principles of the FCL model with the student-populated dynamic knowledge base. Students achieved both individual and group success in meeting learning outcomes through individual inquiry and collaborative, active learning, with the knowledge base providing a forum for students to share their research and access ideas for their inquiry

Supporting Adolescent Metacognition in Engineering Design Through Scripted Prompts from Peer Tutors: A Comparative Case Study

In 2013, developers of the Next Generation Science Standards implemented national K -12 directives and elevated engineering design to the level of scientific inquiry. Teaching design, however, is challenging to educators due to the complex nature of design problems, which cannot be solved via simple algorithms. Solving design problems requires a more reflective and iterative approach that emphasizes metacognitive skills like planning, monitoring, and taking another person’s perspective. Educators are further challenged by children’s immature metacognitive skills, which may be insufficient to engage in the entire design process. A qualitative study of paired seventh graders demonstrated a pragmatic learning activity for enhancing adolescent designs during their earliest phases through guided peer interactions with metacognitive prompts. Four distinct interaction styles were observed among the pairs. Each style varied by which verbal and social phenomena were used to make changes. The metacognitive prompts used in the learning activity can be adapted to any design challenge. Furthermore, an additional, exploratory case demonstrated a restructuring of the learning activity in which the metacognitive prompts were generated naturally by the students themselves. The student-generated prompts were design-specific and timely; delivered in the moment when a student was struggling with a design element. The result was a dynamic co-construction and co-ownership of the designs
