Towards rigor of online interaction research: Implications for future distance learning research
No full textFor the past decade, distance learning research has shifted the focus from defining the notion of distance as a physical proximity or separateness to a psychological construct such as social presence. We have also witnessed the increasing number of research studies that have examined the role of interaction as a way to minimize psychological distance. However, the overall quality of online interaction research has been questioned due to the lack of rigorous methods, and the overly-positive assumption about the relationship between quantity and quality of interaction. This theoretical paper argues that future online interaction research in the area of distance learning should move beyond merely comparing the types or amounts of interaction, and that more rigorous criteria should be employed to design, implement and evaluate online interaction research studies. This paper presents a design-evaluation framework particularly focusing on the three dimensions of learning research on interaction: a) the conceptualization of interaction, b) the tight coupling of the pedagogical-technological design, and c) the valid and reliable evaluation. It is hoped that this paper will highlight critical theoretical and methodological issues for future research to consider for the advancement of our knowledge on the role of interaction in distance learning environments. © The Turkish Online Journal of Educational Technology.11Nssciahciscopu

Location matters: Leveraging knowledge building with mobile devices and Web 2.0 technology
No full textThis article examines the potential of mobile computing and Web 2.0 technology to support knowledge building in formal and informal settings. Desktop-based knowledge building tools have limited affordances of supporting one-to-one access, learning in situ, and seamless integration in and out of school environments. In this initial study, we explore how recent advances of mobile and Web 2.0 technologies can be utilized to support seamless knowledge building processes and to enhance contextualized learning experiences across multiple locations. Using design research as a methodological framework, we analyzed current practices and configurations of mobile learning in one primary school in Singapore, and codesigned a learning scenario with teachers toward seamless knowledge building experiences. The artifacts of primary grade 4 students created in the Google Maps space were analyzed to examine the knowledge building processes based on a location-based mobile learning scenario. We conclude by discussing both possibilities and challenges of knowledge building using mobile Web 2.0 technologies based on our early experiences. © 2009 Taylor & Francis.1128Nssciscopu
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Learning about problem-based learning: Student teachers integrating technology, pedagogy, and content knowledge
No full textWhat should constitute knowledge bases that we expect our future teachers to gain related to pedagogically sound technology integration? Employing the Shulman's teacher knowledge base as a theoretical lens, this study examined the complexity of pre-service teachers' technological pedagogical content knowledge (TPCK) in the context of integrating problem based learning (PBL) and information and communications technology (ICT). Ninety-seven pre-service teachers in this study engaged in a collaborative lesson design project where they applied pedagogical knowledge about PBL to design a technology integrated lesson in their subject area of teaching. Data were collected from two sources: survey and lesson design artifacts. Data analyses revealed that while participants had theoretical understandings of pedagogical knowledge about PBL, their lesson designs showed a mismatch among technology tools, content representations, and pedagogical strategies, indicating conflicts in translating pedagogical content knowledge into designing pedagogically sound, technology integrated lessons. The areas that students perceived to be particularly challenging and difficult include: a) generating authentic and ill-structured problems for a chosen content topic, b) finding and integrating ICT tools and resources relevant for the target students and learning activities, and c) designing tasks with a balance between teacher guidance and student independence. The present study suggests the potential of two explanations for such difficulties: lack of intimate connection among beliefs, knowledge, and actions, and insufficient repertoires for teaching with technology for problem based learning.11Nssciscopu
