Technological Pedagogical Content Knowledge (TPACK) for Pedagogical Improvement: Editorial for Special Issue on TPACK

Mishra and Koehler’s (2006) framework for technological pedagogical content knowledge (TPACK) is one of the most well-received and widely researched theoretical frameworks for technology integration in the classrooms. Chai et al. (2013) recent review found that more than 70 articles about TPACK have been published between 2003 and 2011 within the Scopus database. A website dedicated to TPACK research (http://tpack.org/) has accumulated more than 450 articles. The SSCI-listed journals have also published 134 articles on TPACK as of May 2015. As an analytical and creative framework, TPACK research can potentially generate deeper knowledge construction about ICT integration among researchers and educators. It could be refined, expanded, and improved upon to account for more variables that shape, empower, or constrain the development of ICT use in education (Chai et al. 2013; Voogt et al. 2013). Building upon Shulman’s (1986) model for pedagogical content knowledge, Mishra and Koehler (2006) added the dimension of technological knowledge and demonstrated how various kinds of teacher knowledge can be derived from the integration of technological, pedagogical, and content knowledge. These integrated forms of knowledge are pedagogical content knowledge (PCK), technological content knowledge (TCK), technological pedagogical knowledge (TPK), and technological pedagogical content knowledge (TPACK). Together with technological knowledge (TK), pedagogical knowledge (PK), and content knowledge (CK), these seven kinds of knowledge make up the TPACK framework. While this framework provides specifications for the kinds of teacher knowledge involved during technology integration, how teachers, educators, and researchers can create more technological pedagogical content knowledge need to be further unpacked. Tee and Lee (2011) have aptly positioned generating TPACK as a knowledge creation endeavor and Kramarski and Michalsky (2010) have found it necessary to support pre-service teachers’ metacognitive self-regulation as they create TPACK through design. The creation of knowledge is a complex matter and coupled with the situated nature of TPACK (Mishra and Koehler 2006); further theorizing of the epistemic nature and processes involved in creating TPACK are needed. Specifically, the TPACK framework specifies what teachers need to integrate technology but not how the process can be improved (Cox and Graham 2009). On the other hand, there is much emphasis on the use of technology to support pedagogical improvements, especially the kinds of pedagogies that support students to foster twenty-first century competencies (ISTE 2007; P21, 2007). Voogt and Roblin (2012) have identified ICT-based learning as a common element across all twenty-first century learning frameworks they have reviewed. ICT could be used as a cognitive tool, metacognitive tool, and epistemic tool to support critical thinking, creative and inventive thinking and authentic problem solving, which are also common elements of twenty-first century learning. Yet, there is still a lack of understanding about how the seven TPACK constructs are being applied by teachers as they formulate technology-integrated lessons to promote twenty-first century learning & Joyce Hwee Ling Koh joyce.koh@nie.edu.sg

Ohmage

Participatory sensing (PS) is a distributed data collection and analysis approach where individuals, acting alone or in groups, use their personal mobile devices to systematically explore interesting aspects of their lives and communities [Burke et al. 2006]. These mobile devices can be used to capture diverse spatiotemporal data through both intermittent self-report and continuous recording from on-board sensors and applications. Ohmage (http://ohmage.org) is a modular and extensible open-source, mobile to Web PS platform that records, stores, analyzes, and visualizes data from both prompted self-report and continuous data streams. These data streams are authorable and can dynamically be deployed in diverse settings. Feedback from hundreds of behavioral and technology researchers, focus group participants, and end users has been integrated into ohmage through an iterative participatory design process. Ohmage has been used as an enabling platform in more than 20 independent projects in many disciplines. We summarize the PS requirements, challenges and key design objectives learned through our design process, and ohmage system architecture to achieve those objectives. The flexibility, modularity, and extensibility of ohmage in supporting diverse deployment settings are presented through three distinct case studies in education, health, and clinical research.

Generations of Technology Intelligence in the SMEs

Technology intelligence is important among the management researchers in order to present best service and product, increase diversity and flexibility, and speed the process of production and innovation. On the other hand, identification of the situation of organizations in technology intelligence is a key subject in the researches. This research is a survey to review and characterize the generations of technology intelligence in the companies located at a science park. The results show most companies are in the third generation of technology intelligence from the two indicators entitled “approach for information evaluation” and “characteristics of technology management”. However, indicators entitled “organization of technology intelligence” and “approach for communication” should be considered more as their positions have less considerations to the third generation. The contributions can help science and technology policymakers and researchers, as well as the SME owners to formulate appropriate development strategies for business environment.

Understanding the relevance of ethics reviews of ICT research in UK computing departments using dialectical hermeneutics

Purpose– The purpose of this paper is to attempt to investigate how Information and Communications Technology (ICT) researchers in UK computing departments address ethics in their research. Whilst research and innovation in ICT has blossomed in the last two decades, the ethical, social and legal challenges they present have also increased. However, the increasing attention the technical development receives has not been replicated in the area of developing effective guidelines that can address the moral issues inherent in ICT research.Design/methodology/approach– This research is qualitative and made use of interviews. The data analysis was done with dialectical hermeneutics. Through a dialectical hermeneutic process, this research unpacks different understandings of relevance attached to ethics reviews of ICT research in UK computing departments.Findings– The findings include that ethics reviews are relevant because; it is a moral duty, it improves trust for researchers, it is part of risk assessment, it is in compliance with the law and it is a sustainable act.Practical implications– These various understandings illustrate an important dialectic process on the current state of the art in ICT research.Social implications– It asks to what degree the currently dominant model of ethics review based on biomedical ethics is optimal to ICT.Originality/value– It proposes a framework that can effectively help researchers and administrators to ensure responsible research and innovation in ICT. Finally, it identifies that ICT researchers would benefit from the developing repertoire of responsible research innovation.

Constructivist Research in Smart Tourism

Smart tourism is a social phenomenon arising from the convergence of information technology with the tourism experience. New ways of doing business, new patterns of experience and new problems concerning tourism destination image management and marketing are emerging due to the ubiquitous presence and influence of the internet and mobile devices. New conceptual tools are also available to enable researchers to further understand the social implications as well as the practical implementation of these new virtual and augmented smart tourism ecosystems. To this effect this paper introduces the constructivist paradigm and associated research methodologies as another toolbox for interpreting how smart tourism works as a form of soft power. The implications revealed by constructivism are that through smart tourism ecosystems, destination commodification and commoditization, experience and image formation are increasingly self-per-petuating, autonomous and organic social constructions. Researchers in information technology can use con-structivist research to further explore these dynamic developments in smart tourism.

The Visual Invention Practices of STEM Researchers

This article presents results from a qualitative pilot survey of science, technology, engineering, and math (STEM) researchers concerning techniques used to create graphics for research articles. The survey aimed to induce a methodological vocabulary for a larger project designed to describe and improve STEM visual literacy for nonexperts. However, the survey also revealed interesting problems for investigation—chief among them a mismatch between STEM visual pedagogy and praxis. In addition, participants supplied a handlist of STEM visual communication texts that have informed their praxis. Survey results are presented in the form of a topology—a frequency-based representation of the topics framing participants’ discussion of STEM visual invention.

The Quality of Mathematics Education Technology Literature

Background: The present study evaluated the quality of 1,165 scholarly literature papers about mathematics education technology literature.Purpose: The purpose of the present study was to determine the extent to which mathematics education technology literature reports the information needed to support the scientific basis of a study.Setting: N/AIntervention: N/AResearch Design: A systematic review was used to organize the data collection and analysis processes Data Collection and Analysis: A literature search was conducted to identify scholarly papers that addressed the use of technology in mathematics education. A coding process was developed to record descriptive information about each paper. The Quality Framework developed for this process provided a structure to identify key information across research types based on types of analyses conducted, assigning a certain number of possible points based on the type of research conducted.Findings: Dissertations accounted for a surprisingly high portion of the literature and research: 39.7% of the available literature and 57.0% of the research studies. The overall quality of the mathematics education technology literature was lower than we expected, averaging only 48.9% of the points possible. We noted that the quality of research papers, with respect to possible point values averaged 54.6% over four decades. For mathematics education technology researchers, manuscript reviewers, and editors, these results suggest that more attention is needed on the information being included and excluded from scholarly papers, especially with regard to connections to theoretical frameworks and research designs.

Mechanically Actuated Stance-Control-Orthoses: Advantages, Design Evaluation and Future Directions

Engineers and researchers have devotedly sought to improve and develop the design of walking assistive devices in last few decades to enhance the mobility of impaired individuals. The progress is quite impressive but a lot of design challenges are still remain in making these designs user-friendly and commercially viable. Patients with weak quadriceps have limited option to walk independently. Knee-ankle-foot orthosis (KAFO) are typically prescribed as walking assistive device. KAFOs keep the knee in full extension to provide knee stability during walking and keep knee straight throughout the gait cycle with mechanical locking system. Locked knee in the swing phase leads to an abnormal gait pattern. Mechanical stance control orthosis (SCO) is designed to release the lock during swing phase to allow free knee motion and lock it again during stance phase with mechanical actuation system. It helps the user to walk more natural way by overcoming the limitations of KAFO. This article discusses the advantages of SCOs over KAFOs, analyses various mechanisms, shows comparison and future directions to overcome design challenges. This article will help the researchers in assistive technology to develop a reliable and user-friendly product for common users with lower cost.

Widening participation in technology design: A review of the involvement of children with special educational needs and disabilities

This article presents a review of the design methods and techniques that have been used to involve children with special educational needs and/or disabilities (SEND) in the technology design process. Situating the work within the established child-computer interaction research sub-field of participatory design, we examine the progress that has been made in relation to the participation of this specific child population. An extensive review of the literature in this area has been undertaken and we describe the different roles, responsibilities and activities that have been undertaken by both the child and adult participants within previous technology design projects. We also highlight the different types of outcome from this previous work involving children with SEND, exploring the impact the children's participation has had on both the resulting technology as well as the impact on the child participants themselves. Finally we conclude this review with a set of reporting recommendations for technology designers and researchers aiming to involve this population in future technology design projects.

Applied Doctorates in IT: A Case for Designing Data Science Graduate Programs

There is an increasing shortage of applied Information Technology (IT) researchers which will affect many organizations. Programs at the Master’s level can provide more technicians who can handle some of the workload, but we argue and propose that only an applied doctorate would help fill the gap in advanced skills. This approach follows similarly styled programs in other technical fields experiencing advanced skills shortages, e.g., nursing. While an applied doctorate could be viable in many areas of IT, the analytical skills needed for sophisticated data analysis requires the training that only a doctoral level program can provide. This article outlines a model for creating an applied doctorate in IT, using data science as an example. The program created by following this model could be self-sustaining by leveraging corporate funding for existing employees and sponsorship of new students to supplement more traditional sources of scholarships.

Evaluation of patient involvement in a health technology assessment.

We sought to evaluate patient involvement (consultation and direct participation) in the assessment of alternative measures to restraint and seclusion among adults in short-term hospital wards (in psychiatry) and long-term care facilities for the elderly. We conducted individual semi-structured interviews with thirteen stakeholders: caregivers, healthcare managers, patient representatives, health technology assessment (HTA) unit members, researchers, and members of the local HTA scientific committee. Data were collected until saturation. We carried out content analysis of two HTA reports and four other documents that were produced in relation with this HTA. We also used field notes taken during formal meetings and informal discussions with stakeholders. We performed thematic analysis based on a framework for assessing patient involvement in HTA. We then triangulated data. For the majority of interviewees, patient consultation enriched the content of the HTA report and its recommendations. This also made it possible to suggest other alternatives that could reduce the use of restraint and seclusion and helped confirm some views and comments from healthcare professionals consulted in this HTA. The direct participation of patient representatives enabled rephrasing of some findings so as to bring the patient perspective to the HTA report. Patient consultation was seen as having directly influenced the content of the HTA report while direct participation made it possible to rephrase some findings. This is one of few studies to assess the impact of patient involvement in HTA and more such studies are needed to identify the best ways to improve the input of such involvement.

Visualization of co-readership patterns from an online reference management system

In this paper, we analyze the adequacy and applicability of readership statistics recorded in social reference management systems for creating knowledge domain visualizations. First, we investigate the distribution of subject areas in user libraries of educational technology researchers on Mendeley. The results show that around 69% of the publications in an average user library can be attributed to a single subject area. Then, we use co-readership patterns to map the field of educational technology. The resulting visualization prototype, based on the most read publications in this field on Mendeley, reveals 13 topic areas of educational technology research. The visualization is a recent representation of the field: 80% of the publications included were published within ten years of data collection. The characteristics of the readers, however, introduce certain biases to the visualization. Knowledge domain visualizations based on readership statistics are therefore multifaceted and timely, but it is important that the characteristics of the underlying sample are made transparent.

From this survey, certain patterns emerge regarding the issues investigated and the technologies researchers focus on, in order to address the said issues. Finally, the existing open issues are summarised, and directions for future research are given. Copyright © 2014 John Wiley & Sons, Ltd.

Minimum data generation for Telugu speech recognition

A morphologically rich language has hundreds of forms of each word which makes storing and maintaining them time and resource consuming. It also leads to confusions while recognizing speech which leads to more word error rate. These issues make it difficult to build applications of speech recognition for such languages. Hence there is a need to develop a phonetically balanced minimal data set. This paper describes generating minimum dataset for Telugu language, the second most widely spoken language in India. Considering minimum data generation as a set covering problem, a variety of datasets are generated based on different criteria. From various set covering algorithms, Greedy algorithm is chosen. The criterion used for final data selection is the frequency of occurrence of words. As set covering requires a large set of data from which minimum data is selected, a 15 Million word text corpus has been created. Thorough analysis of this text corpus is carried out in order to ensure that the generated set is phonetically balanced. The generated minimum dataset consists of 21 words and covers each phoneme of the Telugu language. Telugu speech technology researchers can benefit from this data set in building applications of phoneme level speech recognition by reducing manual recording effort and time. This paper discusses the role of minimum data set in LVSR systems, details of the text corpus created and proposed algorithm for minimum data generation.

A Survey of Mathematics Education Technology Dissertation Scope and Quality

We examined 480 dissertations on the use of technology in mathematics education and developed a Quality Framework (QF) that provided structure to consistently define and measure quality. Dissertation studies earned an average of 64.4% of the possible quality points across all methodology types, compared to studies in journals that averaged 47.2%. Doctoral students as well as their mentors can play a pivotal role in increasing the quality of research in this area by attending to the QF categories as they plan, design, implement, and complete their dissertation studies. These results imply that mathematics education technology researchers should demand greater clarity in published papers through the preparation of their own manuscripts and how they review the works of others.

Conceptual design and RCS property research of three-surface strike fighter

This paper mainly focuses on the conceptual design and stealth performance of the three-surface military aircraft. A threedimensional (3-D) digital mock-up of the three-surface strike fighter with stealth feature was designed and the schemes of carrying missiles were analyzed in CATIA. Based on physical optics principle and the Method of Equivalent Currents (MEC), a numerical simulation of the RCS feature of the aircraft was carried out with RCSPlus which is a software designed by Beihang University. The paper contributes to the RCS feature analysis of the whole plane and different parts on X-band, S-band and UHF-band and a comparison of RCS feature to Su-37 and T-50 military aircraft is drawn. On X-band, the pitch angle of the incident wave was 0°, and the result shows: (1) Compared with Su-37 aircraft, the forward scattering RCS of the three-surface strike aircraft was reduced to 14.9%, the side scattering RCS to 9.6% and the back scattering RCS to 40.2%. (2) Compared with T-50 aircraft, the forward scattering RCS was reduced to 38.61%, and the side scattering RCS to 67.26%. This paper should be useful for researchers in conceptual design and stealth technology of the military aircraft.

Foucault's toolbox: critical insights for education and technology researchers

Despite having been a prolific academic, whose work exerts considerable cross-discipline influence, the ideas of Foucault are largely neglected in educational technology scholarship. Having provided an initial brief overview of the sparse use of Foucault's work in this sub-field, this paper then seeks to generate new understandings, arguing that his texts have ongoing relevance, particularly if ed-tech research is to escape its limited, instrumentalism and critically engage with broader social, economic and political concerns. To this end Foucault's writings on technology, discourse and panopticism are considered and the analytical insights they offer into educational technology research explored. Whilst recognising that it is impossible to do justice to Foucault's oeuvre in such a short piece, it is hoped that through providing an introduction to these key concepts and suggesting problems that they could be used to addresses a more critical approach to educational technology will be engendered.
