<p> The purpose of this quasi-experimental quantitative study was to investigate whether online interactive simulations would provide a positive improvement in learners&rsquo; ability to apply critical thinking skills in a dangerous work environment. The course in which an improvement in critical thinking skills was the target outcome was a course which addressed electrical safety-related work practices for electrical apprentices in dangerous work environments. The interactive simulation identified for this study provided different levels of high-fidelity simulations in a dangerous electrical environment, in which the learner was subjected to scenarios where that learner could face simulated injury or death. Critical thinking was measured by a post-Test instrument developed using a DELPHI process and designed to evaluate critical thinking skills in electrical scenarios presented in the simulation. An Independent Samples t-Test was conducted to determine if there was a significant difference, as determined by the post-Test, between a comparison group that did not use the simulation and an experimental group who did use the simulation. In this study, there was no significant difference between the comparison group and the experimental group on the post-Test. The theoretical framework examined in this study included constructivism, self-guided study, cognitive overload, and motivation; and the effect of each was discussed in the study. This research study identifies the need for additional research into the best use of interactive simulations in online course development.</p>

<p> The purpose of this research was to understand the perspectives of teachers and students regarding their use of specific e-textbooks in a higher education learning environment. The e-textbooks used by the teachers and students were examined in order to determine functions and features to focus on during the inquiry. This study was particularly interested in the design of e-textbooks and how they are used by both teachers and students in the learning process. The participants in the research were also prompted to suggest improvements to e-textbooks. </p><p> A case study approach was used as the methodology to examine three teachers represented three majors in three different colleges and a small sample of their students to gather information to answer the research questions. Qualitative data from multiple sources such as in depth interviews and document reviews were used to analyze and examine the overall utility of e-textbooks toward learning/teaching, and functions related to the instructional and navigational design of e-textbooks. </p><p> Results of this study showed that there was overall agreement that choosing books needs to be based on the quality of the material contained within the book, regardless of the format, print or electronic. E-textbooks facilitate teachers&rsquo; and students&rsquo; interactions and access to the materials and resources. However, both teachers and students viewed their e-textbooks as supplementary materials, even thought these e-textbooks allowed them to interact with the text using different tools. One recurring finding was how flexible e-textbooks are in individualizing student learning. Recommendations by students/teachers included the improvement of page layout, the interface, increasing window size, providing more complex tasks, keeping up with technology, and insuring the quality of information within the e-textbook. Implications for future research include further investigation into the use of e-textbooks as supplementary materials, and whether printed texts are also being considered as supplementary. Finally, there are indications that advanced technology may be changing how students learn and if e-textbooks reflect this change. Further research into this possible change in ways that students learn would shed additional light on this question.</p>

<p> The influence of technology on society shows little sign of diminishing (Puybaraud, 2012). Increased capabilities and the affordability of technology devices have brought a resurgence of one-to-one device implementation in schools (Dawson, 2016). This qualitative study was designed to elicit the perceptions of administrators and teachers on one-to-one device implementation. Marc Prensky&rsquo;s (2001) premise that students are digital natives embedded in media and digital device-rich environments provided the conceptual framework for this study. Furthermore, Prensky (2001) proposed modern students learn, conceptualize, and respond differently than previous generations. The participants in this study represented six southwest Missouri school districts with student populations of 300-2,500 in grades 6-12 which underwent one-to-one device implementation within the last five years. Data were gathered from responses of eight teachers, 11 principals, and five superintendents. Perceptions of principals and teachers in school districts implementing one-to-one devices were gathered during the first phase of data collection. These data were transcribed and analyzed for key words and phrases, as well as common themes. Then, during the second phase of data collection, an electronic questionnaire instrument was used to gain feedback of participating superintendents. The following findings emerged from this study: appropriate time, importance of key personnel, shifts in teaching, and shifts in learning through the one-to-one implementation process.</p>

<p> Independent school leaders are seeking opportunities to improve their organizations&rsquo; impact on mission (Collins, 2005; Mair &amp; Marti, 2006), respond to the new affordances and expectations driven by information and communications technologies (Christensen, Horn, &amp; Johnson, 2008; Cuban, 2013), and improve their financial sustainability (Baumol &amp; Bowen, 1966; Farkas, 2012; Ewert, 2013). The answer to similar challenges in other fields has been innovation (Christensen et al., 2008; Schumpeter, 1949). However, there is a gap in the research&mdash;an absence of a theory of practice for the work of identifying, enacting, and diffusing value-adding changes, or innovations, throughout independent K&ndash;12 schools. As a first step in developing such a theory of practice, this exploratory qualitative study focuses on independent school leaders identified by their peers as innovative and working at independent U.S. K&ndash;12 schools that have been defined as representative through the metrics of enrollment, tuition, endowment, and length of operations. Via a process of structured interviews, archival document review, member checks, and researcher writing, this study explores and seeks to understand these particular leaders&rsquo; perceptions, conceptualizations, and thinking about innovation, and their efforts in relation to the enactment of innovation in their particular school contexts. The major findings of this study are: (a) innovation is an under-theorized area of practice for leaders of independent schools; (b) the conceptualizations of innovation of Heads of independent schools are varied among individual leaders depending on several factors; (c) conceptualizations of innovation by Heads affect their approaches to innovation and leading innovation adoption; and (d) the field of independent schools lacks an approach to innovation that would help contain cost growth. The conclusion of this study is a call for a new theory of practice for independent school leaders regarding innovation, informed by theory from various fields and grounded in the experiences of leading practitioners.</p>

<p> This qualitative, exploratory study grouped together and explored custom-built environments for communities of online informal learning (COILs) with a special lens on the socio-technical relationship of platform tools, structures, and strategies that lead to social learning. The study was conducted through a three-phase process. First, a list of possible candidate sites was analyzed for appropriate fit based on the defining terms of a custom-built COIL environment. Second, an observational content analysis was implemented on 10 of the sites to aggregate a list of the tools, structures, and strategies used in the sites. Lastly, the same 10 sites and the lists of tools, structures, and strategies were researched through both pre-established codes for sociability, usability, and community-building designs and an open exploratory observation of their uses with a focus on the way these features support COILs. Social learning and informal learning were also purposefully scrutinized while themes regarding personalized learning and sustainability also emerged from the exploration. All design themes were found represented within the sites, as were social learning, informal learning, personalized learning, and efforts toward sustainability. </p>

<p> Each year, a growing number of K&ndash;12 students participate in some form of online instruction (Watson et. al, 2015). This transition to online learning environments raises questions about the design and distribution of curricula in K-12 educational systems. This dissertation explored the perceptions of K-12 online educators regarding the significance and challenges associated with teaching social and emotional learning (SEL) and character education skills in online learning environments. The SEL related efforts of current online instructors are compared to the best practices in character education and SEL known to be effective in traditional classroom settings. A mixed-methods approach of using a questionnaire to gather data and then conducting interviews was employed. Seventy-one K-12 online educators responded to the questionnaire with a smaller group of six participating in follow-up interviews. The ethics of care (Noddings, 2005) and social responsibility (May, 1996; Dewey, 2009) provided the theoretical lens for this study. Additionally, the Social Development Model (Hawkins &amp; Weis, 1985; Catalano &amp; Hawkins, 1996) was used as an analysis tool to gauge whether the online educators&rsquo; purported integration of social and emotional learning and character education met what the Social Development Model proposes is necessary to develop prosocial behaviors.

The objetive of the present thesis is to develop and test out a systematic approach to the analysis, design and implementation of Telecommunications-Supported Training (TST) systems. The Literature Review offers a set of approaches to similar problems in the field of Information Systems. Several other disciplines have also been considered: Psychology of Human Factors, Organizational and Innovation Theory, and applied research being currently carried out under the EU DELTA Programme. A global User-Centred Model of TST has been developed, based on the wellestablished principles of Systems Engineering and Soft Systems Methodology. The theoretical basis for this model is the concept of TST Architecture, conceived as a functional arrangement of technical components which are introduced in order to improve the performance of the actors involved in the system. The other key aspect is the design of a set of Adoption Strategies, aiming for the creation of the necessary conditions to achieve user acceptance of the technologies implemented. Following these principles, the ADAM (Architectural Design and Adoption Model) systematic approach is developed. It is structured in five stages: Context Analysis, System Analysis, System Design, System Implementation and System Maintenance. Each stage is structured into steps and activities, described in terms of key points, outcomes, deliverables, and roles involved. The ADAM approach has been tested out in its twofold dimension of analyzing already implemented TST systems and designing new ones. The first case discusses the application of ADAM to the EU Multimedia TeleSchool (MTS) TST system. The test is completed by discussing the design and implementation, performed by the author, of a TST system at the Universidad Politecnica de Madrid. The results confirm the usefulness of ADAM both for practitioners and researchers in the field. Also, the TST model is extended as regards the components of acceptance and adoption, and their impact on the introduction of technologies in organizations.

<p> The objectives of this study were to gain an understanding of how practicing teachers believe they are prepared to meaningfully and critically integrate technology into their classroom practices; and to understand how practicing teachers recruited those beliefs into their teaching practices. This included gaining an understanding of what they believed led to their engagement in the critical dimensions of technology use in their teaching practices. This mixed-methods study contained two phases. In Phase 1, 58 graduate students in a College of Education completed a newly developed Critical Technological Pedagogical Content Knowledge (C-TPACK) survey containing likert-scale and open-ended questions. A subset of four graduate students, who were also practicing teachers, participated in Phase 2 of this study where lesson plans, observations, and interviews were analyzed. The findings indicated that limited training in and exposure to C-TPACK during teacher education coursework and professional development (PD), uncertainty about students&rsquo; critical digital literacies (CDL), the teachers&rsquo; varying understandings of CDL, resource limitations and restrictive school policies posed barriers for the teachers&rsquo; recruitment of CTPACK to their practices. These findings showed the importance of tying critical theory to technology in education coursework and PD programs. This study proposes the use of a theoretical framework that prioritizes critical theory, namely the C-TPACK framework, when analyzing teachers&rsquo; technology integration practices.
