This research focuses on a Knowledge Building pedagogical approach and investigates ways to boost students’ competencies in knowledge creation processes, specifically their ability to contribute productively to high-level explanation-seeking discourse. This study uses a design-based methodology to explore how pedagogical and technological innovations can enhance students’ ways of contributing to knowledge building discourse, and examines whether expanding students’ contribution repertoire helps them to advance community knowledge in general. Gains associated with a Knowledge Building approach for secondary and post-secondary students are widely documented. This research adds to this body of literature by showing how a Knowledge Building approach can be productively engaged at the early primary level. This work also contributes to studies exploring automated feedback and assessment tools that can help boost student capacities for building new knowledge. The research was conducted in three main phases. The first phase mapped the ways that students from Grades 1-6 (n = 102) contribute to their naturally occurring Knowledge Building discourse in order to provide baseline data for subsequent design experiments. The following two phases corresponded to two design iterations that involved work in Grade 2 science and that tested different types of formative feedback. Design Cycle 1 (n = 42) focused on testing supports to boost low-frequency contribution types. Design Cycle II (n = 43) aimed to reproduce and improve results from the first iteration. In both design cycles, pedagogical supports included whole-class metadiscourse sessions, while technological supports consisted of contribution and content-oriented feedback tools that offered students a meta-perspective on their own discourse, including Word Clouds (Cycle 1), Concept Clouds (Cycle 1-2), visualizations produced by the Metadiscourse Tool (Cycle 1-2), and verbal scaffolds (Cycle 1-2). Analyses of data revealed that these supports helped students to significantly increase their engagement with targeted contribution types, diversify their general contribution repertoire, and advance collective knowledge beyond that attained by their peers in prior years. This research provides empirical evidence that Knowledge Building inquiry can be effectively engaged at the primary level, and offers usable artifacts tested and shown to be conducive for helping young students raise the level of their Knowledge Building discourse.

This thesis explores teaching practice as a function of years of experience with Knowledge Building pedagogy, emphasizing teachers’ continual improvement of practice while they foster continual improvement of students’ ideas. Knowledge Building practice places students’ ideas at the centre of the classroom enterprise, with the principal challenge being enabling students to take effective responsibility for improvement of ideas. Building on a variety of models of teacher thinking and development, a problem space model is developed specifically geared to the development of Knowledge Building practices. This model is used to guide the investigation and provide a theoretically- and empirically-based description of shifts teachers undergo as they gain skill in Knowledge Building pedagogy. The model also serves to convey how Knowledge Building teachers differ from other skillful teachers. The principal shift is from a centrist to relational (or systemic) perspective. This perspectival shift is examined in five problem spaces: Curriculum/Standards, Social Interaction, Student Capability, Classroom Structures and Constraints, and Technology. Underlying the centrist perspective is a belief in established procedures and goals typically understood to characterize effective teaching. Underlying the relational perspective is a belief in the capacity of students to develop and improve their own ideas, and a belief that in doing so students will not only mature as knowledge-builders, but will also excel in the achievement of traditional knowledge goals. The research uses multiple data sources (teacher meetings, journals, interviews and classroom observations) to analyze the work of 13 teachers over a full school year, with three embedded case studies. Results show that Knowledge Building teachers construct and explore the same problem spaces as other teachers. What distinguishes them, and places them on a different trajectory, is the relational approach that brings ideas to the centre in each problem space. The work of teachers with different levels of experience is analyzed to characterize the centrist to relational shift, which corresponds to three embedded shifts (a) surface to deep interpretation of problem and processing of information, (b) routine to adaptive approach to classroom activities and student engagement, and (c) procedure-based to principle-based reflective action.

This case study examined the spread of ideas in a Gr. 5/6 classroom in which the teacher was attempting to foster a knowledge building community. The goal of the research was to explore the relationship between the social network of the classroom (in terms of face-to-face and computer-mediated interactions), the teacher’s role, and the spread of ideas. Further, the thesis examined how social network tools may help teachers better understand the pedagogical implications of Scardamalia and Bereiter’s (1991) Teacher A, B, C models. Analyses of videotaped lessons revealed the teacher used a complex mix of traditional instructional methods and knowledge building strategies while trying to shift the locus of control of learning to students. Critical teacher-driven processes included the class-wide adoption of knowledge building vocabulary and practices, and efforts to foster higher levels of student-student discourse. Analyses of online interactions provided strong evidence of highly interconnected student-student online networks, with the note reading network being especially dense. Longitudinal studies revealed these network established themselves early in the unit, and persisted during the course of the inquiry. There was evidence that idea improvement was present in addition to idea spread. In face-to-face classroom communication, the teacher’s role was more central, particularly in "Knowledge Building Talk" sessions. However, here too, the teacher made efforts to shift the locus of control. Overall the analyses suggest that social network tools are potentially useful for helping teachers make the difficult transition from "Teacher A" and "Teacher B" strategies, in which the locus of control is with the teacher, to "Teacher C" strategies, in which strategic cognitive processes are turned over to students. This dissertation proposes that movement toward Teacher C practices may be illustrated, in part, by a shift in classroom network topologies from that of a star-shaped network, centered on the teacher, to a highly interconnected student-student network. Finally, the thesis recounts a number of ways in which the use of social network tools uncovered discourse patterns of which the teacher was unaware, including gender differences in reading, building-on, and contribution patterns.

This thesis investigates issues and challenges surrounding the use of teacher study groups as a means of addressing the gap that must be closed between design principles and classroom practices in order to effectively implement an educational innovation. A multiple-case design was used to examine how teachers’ perceived understanding of the Knowledge Building Communities principles changed over time and affected their implementation of the Knowledge Building Communities model—a model that requires student engagement in the collaborative production of ideas that are continually improved by all participants. Knowledge Forum® is an on-line environment designed to support Knowledge Building. Data sources for this study include teacher interviews, transcripts of study group meetings, teachers’ ratings of their perceived understanding of Knowledge Building principles, teacher and student activity in Knowledge Forum, and student interviews. In total this study involved seven teachers and eleven study group meetings across three school sites. Based on work at a site already engaged in Knowledge Building a tentative proposition was developed: discussing Knowledge Building principles increases teachers’ perceived understanding of these principles and contributes to increasingly effective designs for implementing them. This proposition was tested and refined at two additional elementary public schools. Taken together the findings suggest the importance of and difficulties surrounding study groups focused on principle-based approaches to pedagogical change. In particular, the findings point to discussion and active engagement with the principles as a catalyst for change. A data analysis technique was developed to examine the discourse patterns of select episodes of study group meetings. The resulting pattern suggests the principles can frame a study groups’ work and set the groundwork for change through discussion of goals underlying the principles, stories relevant to their implementation, and commitment to ongoing experimentation to address obstacles. Detailed accounts of teacher difficulties and change form the basis of a descriptive model developed to convey how teachers address contextual concerns in their study groups, with elaboration of the types of interactions that help them move to deeper understanding of principles and to more successful implementations of the Knowledge Building Communities model.

The use of information and communication technologies (ICT) has now become all pervasive in society. There is now an expectation that educators will use ICT to support teaching and learning in their classrooms and this position is evident in many curriculum documents and educational policies where the aim is to provide each child with access to ICT. Consequently, and to realise this expectation, it is imperative that the focus on the use of information and communication technologies (ICT) in education shifts beyond learning about ICT to a focus that is aligned with the pedagogical learning experiences in which students can be immersed. There is a need for deep knowledge building to occur in these environments for our students to be active participants in a society where new technologies are constantly emerging. Hence, there is a need for learning environments that are flexible and respond to the needs of these new students and can adopt new technologies where necessary. In order to explore such an environment that encourages the development of knowledge building, an argumentative framework is necessary. The purpose of the study described in this thesis was to identify argumentation as a process of knowledge building and determine if it occurs in an online discussion forum, which is situated in a blended learning environment. This blended learning environment is typical of many classrooms and is where there is a combination of traditional face-to-face activity with online collaboration. In the case of this study, it is situated within an upper secondary private girls school located in a metropolitan area. The classroom under investigation demonstrates a blending of traditional pedagogy, that of dialectical reasoning and argument, and new technology, through an online discussion forum. The study employed a research design methodology over a six week period, while the analysis was based on an existing social argumentation schema and a new customised schema. As part of the analysis, descriptive statistics were used to determine the students' activity within the online discussion forum and to ascertain how this varied accordingly when certain criteria were changed. This was consistent with the cyclic approach of design research. Pedagogical recommendations were presented which demonstrated the importance that appropriate scaffolding and the role of the teacher plays in the successfulness of a forum. The study also recognised the need for purposeful teaching of argumentation as a process of knowledge building and the need for starter statements that are personally motivating to the students and are authentic and relevant. Argumentation and consequently knowledge building were evident in the findings, though were constrained by the habituated practices of schooling. Similarly the notion of community, while evident, was constrained by the time- and space- dependence of the school environment.

Experts in the field of molecular and cellular biology (MCB) use domain-specific reasoning strategies to navigate the unique complexities of the phenomena they study and creatively explore problems in their fields. One primary goal of instruction in undergraduate MCB is to foster the development of these domain-specific reasoning strategies among students. However, decades of evidence-based research and many national calls for undergraduate instructional reform have demonstrated that teaching and learning complex fields like MCB is difficult for instructors and learners alike. Therefore, how do students develop rich understandings of biological mechanisms? It is the aim of this dissertation work to explore features of expertise and knowledge building in undergraduate MCB by investigating knowledge organization and problem-solving strategies. Semi-structured clinical think-aloud interviews were conducted with introductory and upper-division students in MCB. Results suggest that students must sort ideas about molecular mechanism into appropriate mental categories, create connections using function-driven and mechanistic rather than associative reasoning, and create nested and overlapping ideas in order to build a nuanced network of biological ideas. Additionally, I characterize the observable components of generative multi-level mechanistic reasoning among undergraduate MCB students constructing explanations about in two novel problem-solving contexts. Results indicate that like MCB experts, students are functionally subdividing the overarching mechanism into functional modules, hypothesizing and instantiating plausible schema, and even flexibly consider the impact of mutations across ontological and biophysical levels. However "filling in" these more abstract schema with molecular mechanisms remains problematic for many students, with students instead employing a range of developing mechanistic strategies. Through this investigation of expertise and knowledge building, I characterize several of the ways in which knowledge integration and generative explanation building are productively constrained by domain-specific features, expand on several discovered barriers to productive knowledge organization and mechanistic explanation building, and suggest instructional implications for undergraduate learning.

<p>The role of web 2.0 technologies has become windfall for knowledge building in higher education in the entire modern world. Web 2.0 technologies (Podcasts, Wikis, and Blogs) are being explored for collaboration, innovation, and creative purposes in digital literacy. The ICT based system (Learning Management System, Student Portal, Web mail) of Växjö University lacks web 2.0 technologies (Podcasts, Blogs, and Wikis) that are important for classroom learning for knowledge building. This research intends to investigate and describe the educational importance of web 2.0 (Podcasts, Wikis, and Blogs) as a possible source to facilitate class room learning in higher education in Sweden. In this regard, role of web 2.0 in its current usage in the teaching and learning have been identified and, thereby, possible measures for more improvements have been suggested in this research. Keeping in view the potential of web 2.0 as content development and management technologies and incorporating their role in formative evaluation of students, peer assessment, collaborative content creation, and individual as well as group reflection on learning experiences, the researcher conducted a survey by asking very simple and short questions as to how far has this potential been exploited in Sweden. Based on the findings and the empirical evidences thereof a model has been proposed for maximum utility of web 2.0 technologies.</p>
