Reading for Idea Advancement in a Grade 4 Knowledge Building Community

This study looks into the reading practice in a Grade 4 knowledge building community that involved 22 students and a veteran teacher. The students investigated light over a threemonth period supported by Knowledge Forum, a networked collaborative knowledge-building environment. The classroom designs encouraged the students to take on high-level responsibility for advancing the community’s knowledge, as represented in their online discourse in Knowledge Forum. The tracing of student conversations in Knowledge Forum and content analysis of their portfolio notes demonstrate productive advancement of scientific understanding. Qualitative analyses of classroom videos, online discourse, and the teacher’s reflection journal characterize student reading practice along four themes: reading for the purpose of advancing community knowledge; as progressive problem solving; embedded in sustained knowledge-building discourse; and as dialogues between local understanding and knowledge in the larger world. These results contribute to elaborating the possibility and processes of integrating reading with creative knowledge work in content areas. Classroom strategies are identified and discussed in relation to the role of collaborative online technologies

The Evidence Hub: harnessing the collective intelligence of communities to build evidence-based knowledge

Conventional document and discussion websites provide users with no help in assessing the quality or quantity of evidence behind any given idea. Besides, the very meaning of what evidence is may not be unequivocally defined within a community, and may require deep understanding, common ground and debate. An Evidence Hub is a tool to pool the community collective intelligence on what is evidence for an idea. It provides an infrastructure for debating and building evidence-based knowledge and practice. An Evidence Hub is best thought of as a filter onto other websites — a map that distills the most important issues, ideas and evidence from the noise by making clear why ideas and web resources may be worth further investigation. This paper describes the Evidence Hub concept and rationale, the breath of user engagement and the evolution of specific features, derived from our work with different community groups in the healthcare and educational sector

Teaching, learning, and knowledge building : the case of the remote networked school initiative

The Remote Networked School (RNS)/« École éloignée en réseau » is an initiative that aims at implementing an innovation with Internet-based technologies in support of teaching and learning as well as knowledge building in small rural schools. The first eight years of the RNS are examined applying Engeström’s activity theory framework, and more specifically the concept of expansive learning wherein we document the 7 stages. Tensions and contradictions are identified to provide an “inside” understanding of what matters when new technologies designed to support co-teaching and co-learning within and between classrooms are introduced. Two activity systems or more shared the same object such that students would engage actively in collaborative online discourse for solving authentic problems. To this end the trajectory of the RNS initiative had to overcome contradictions. As a result an expansive learning cycle was documented

Strategies That Enhance Voice-On Activities In Middle School School Science

Teachers willing to listen over lecture can implement voice-on activities that create equitable learning environments for all learners. Today’s students arrive to us nourished by multiple streams of knowledge gleaned from family, friends, books, games, television, Internet, and various technologies. Equipped with complex layers of knowledge— students have something to say—but how they say and synthesis this information during voice-on activities is paramount for building new constructs. In 2016, the phrase voice-on activities was first used in a middle school science classroom as a cue to model preferred behavior and categorize the following oral activities: argumentation, collaboration, conversations, discourse, discussions, debates, group talk, student talk, presentations, and many more. The purpose of this capstone is to explore the effectiveness of prior knowledge, vocabulary acquisition, and non-digital games as strategies to enhance students’ science literacy and the use of academic language during voice-on activities

Science and Technology Governance and Ethics - A Global Perspective from Europe, India and China

This book analyzes the possibilities for effective global governance of science in Europe, India and China. Authors from the three regions join forces to explore how ethical concerns over new technologies can be incorporated into global science and technology policies. The first chapter introduces the topic, offering a global perspective on embedding ethics in science and technology policy. Chapter Two compares the institutionalization of ethical debates in science, technology and innovation policy in three important regions: Europe, India and China. The third chapter explores public perceptions of science and technology in these same three regions. Chapter Four discusses public engagement in the governance of science and technology, and Chapter Five reviews science and technology governance and European values. The sixth chapter describes and analyzes values demonstrated in the constitution of the People’s Republic of China. Chapter Seven describes emerging evidence from India on the uses of science and technology for socio-economic development, and the quest for inclusive growth. In Chapter Eight, the authors propose a comparative framework for studying global ethics in science and technology. The following three chapters offer case studies and analysis of three emerging industries in India, China and Europe: new food technologies, nanotechnology and synthetic biology. Chapter 12 gathers all these threads for a comprehensive discussion on incorporating ethics into science and technology policy. The analysis is undertaken against the backdrop of different value systems and varying levels of public perception of risks and benefits. The book introduces a common analytical framework for the comparative discussion of ethics at the international level. The authors offer policy recommendations for effective collaboration among the three regions, to promote responsible governance in science and technology and a common analytical perspective in ethics

Exploring the role of materials in policy change: innovation in low energy housing in the UK

We find and prove new Pohozaev identities and integration by parts type formulas for anisotropic integrodifferential operators of order 2s, with s¿(0,1). These identities involve local boundary terms, in which the quantity (Formula presented.) plays the role that ¿u/¿¿ plays in the second-order case. Here, u is any solution to Lu = f(x,u) in O, with u = 0 in RnO, and d is the distance to ¿O.Peer ReviewedPostprint (author's final draft

Building an IT Taxonomy with Co-occurrence Analysis, Hierarchical Clustering, and Multidimensional Scaling

Different information technologies (ITs) are related in complex ways. How can the relationships among a large number of ITs be described and analyzed in a representative, dynamic, and scalable way? In this study, we employed co-occurrence analysis to explore the relationships among 50 information technologies discussed in six magazines over ten years (1998-2007). Using hierarchical clustering and multidimensional scaling, we have found that the similarities of the technologies can be depicted in hierarchies and two-dimensional plots, and that similar technologies can be classified into meaningful categories. The results imply reasonable validity of our approach for understanding technology relationships and building an IT taxonomy. The methodology that we offer not only helps IT practitioners and researchers make sense of numerous technologies in the iField but also bridges two related but thus far largely separate research streams in iSchools - information management and IT management

Collaborative trails in e-learning environments

This deliverable focuses on collaboration within groups of learners, and hence collaborative trails. We begin by reviewing the theoretical background to collaborative learning and looking at the kinds of support that computers can give to groups of learners working collaboratively, and then look more deeply at some of the issues in designing environments to support collaborative learning trails and at tools and techniques, including collaborative filtering, that can be used for analysing collaborative trails. We then review the state-of-the-art in supporting collaborative learning in three different areas – experimental academic systems, systems using mobile technology (which are also generally academic), and commercially available systems. The final part of the deliverable presents three scenarios that show where technology that supports groups working collaboratively and producing collaborative trails may be heading in the near future
