The present study assessed the views of students on school-related determinants with respect to liking or disliking technology. In determining students' views, two self-report instruments, the Classroom Learning Environment Survey (CLES) and Attitudes Toward Science Scale (ATSS) were used. Also, an interview schedule was arranged with a selected group. Participants were 200 first years registered for Diplomas in Primary -, Secondary -, and Technology Education. Results indicated a positive relationship between attitudes towards technology and each of teacher characteristics, student characteristics and the classroom environment. Regression analysis showed that attitudes toward technology were predicted by the three study variables. On the other hand, no statistically significant gender differences were established. Recommendations and suggestions for further research are also advanced. / Mathematics, Science & Technology Education / M. Sc. (Technology Education)

It is important to evaluate and understand the state-of-art technologies to position our research and invest our energy and resources in more effective ways. Unfortunately, no systematic approach has been introduced to evaluate the maturity of technologies except a few models such as Redwine/Riddle's model (Redwine and Riddle, 1985), which does not contain a significant concept, "goals" of technologies. A new goal-oriented, technology maturity evaluation model has been proposed in this present study. The model aids to measure how a technology meets the goal of the technology along with a well-defined procedure. The model has applied to evaluate the maturity of the requirements specification technology as a case study. The results showed that this approach promoted effectiveness of measuring the technology maturity and understanding the state-of-art technology.

With the increasing adoption of health information technology and the growth in the resulting electronic repositories of clinical data, the secondary use of electronic health record data has become one of the most promising approaches to enabling and speeding clinical research. Unfortunately, electronic health record data are known to suffer from significant data quality problems. Awareness of the problem of electronic health record data quality is growing, but methods for measuring data quality remain ad hoc. Clinical researchers must handle this complicated problem without systematic or validated methods. The lack of appropriate or trustworthy electronic health record data quality assessment methodology limits the validity of research performed with electronic health record data. This dissertation documents the development of a data quality assessment framework and guideline for clinical researchers engaged in the secondary use of electronic health record data for retrospective research. Through a systematic literature review and interviews with key stakeholders, we identified core constructs of data quality, as well as priorities for future approaches to electronic health record data quality assessment. We used a data-driven approach to demonstrate that data quality is task-dependent, indicating that appropriate data quality measures must be selected, applied, and interpreted within the context of a specific study. On the basis of these results, we developed and evaluated a dynamic guideline for data quality measures in order to help researchers choose data quality measures and methods appropriately within the context of reusing electronic health record data for research.

Atualmente, as iniciativas de avaliação vêm sendo utilizadas para a legitimação do gasto público e também para a verificação de resultados e impactos, buscando informações qualificadas para o aprimoramento do funcionamento dos programas e apoio nas posteriores tomadas de decisão. Porém, ainda é recente o debate sobre a avaliação dos esforços de pesquisa e desenvolvimento no Brasil, tanto no âmbito público como privado. Frente aos desafios metodológicos colocados pela natureza não linear das atividades de C, T &I e pela multiplicidade de atores envolvidos no processo de inovação, é de extrema relevância a proposição de novas abordagens de avaliação que sejam apropriadas para averiguação dos resultados e impactos de programas de C, T &I. O objetivo do presente trabalho foi contribuir para o avanço de metodologias de avaliação, através do desenvOlvimento e aplicação de indicadores voltados à avaliação do Programa de Apoio à Propriedade lntelectuallNúc1eo de Patenteamento e Licenciamento de Tecnologia (PAPIINuplitec), da Fundação de Amparo à Pesquisa do Estado de São Paulo (F APESP). A escolha do programa para avaliação deveu-se a grande importância da propriedade intelectual para o desenvolvimento econômico das nações e a crescente necessidade da transformação de conhecimentos científicos em inovações para o setor produtivo. Nesse sentido foram apresentados e discutidos os incentivos e obstáculos presentes no processo de obtenção da propriedade intelectual e transferência de tecnologia, essencialmente para instituições públicas de ensino e pesquisa. Para a realização da pesquisa foi utilizada uma abordagem de avaliação multidimensional, orientada pelo método de decomposição. No processo de avaliação, foi desenvolvido um questionário para todos os pesquisadores beneficiários do programa P AP1/Nuplitec que possuíam pedidos de patentes depositados. Ao final, foram obtidas informações qualificadas que possibilitaram a percepção da abrangência do programa, de seus resultados e impactos e também os pontos que devem ser melhorados. Também, foi demonstrada a relevância do programa para o suporte à propriedade intelectual e promoção da cultura de patenteamento no contexto das instituições de pesquisa do Estado de São Paulo / Abstract: The evaluation of research activities is essential for the goverrunental agencies involved in funding large programs of science, technology and innovation (S,T&I). Currently, evaluation initiatives have been used for legitimating of public spending resources and also to verify the resul.ts and impacts of the funded projects. Evaluation of such programs produces qualified inforrnation that can be used for the improvement of the programs and support subsequent decisions on the public and private financing. However, the debate on the evaluation of S, T &I funding in Brazil is recent in both public arid private sectors. ln face of the complexity of the S,T&I system, improved evaluation methodologies have been proposed to collect the results and impacts of these programs in a comprehensive and appropriated manner. ln view of the multiplicity of actors involved and the non-linear nature of the activities developed in the S, T &I programs, the objective of the present work was to contribute for the progress of the evaluation methodologies, through the development and application of appropriate indicators to evaluate the Support for lntellectual Property ProgramlOffice for Patenting and Licensing of Technology (PAPI/Nuplitec), of the State of São Paulo Research Foundation (FAPESP). The choice of the program to be evaluated was due to the enormou's importance of the intellectual property to the nation's economic development and the increasing need for the transformation of scientific knowledge into innovations for the productive sector. The work made the use of the decomposition approach of evaluation, which is based on two axes: the decomposition of the formal objectives of the programs and the dialog with the different actors involved. At the end, the results have shown the relevance of the program to support intellectual property and promotion of culture of patenting in the context of the research institutions of the state of São Paulo / Mestrado / Mestre em Política Científica e Tecnológica

M.Ed. (Media Studies) / Despite the availability I variety and virtually limitless properties of the different types of educational materials and equipment, it would appear that there are still many teachers who are opposed to the use of educational media. For the purposes of this study it was necessary to investigate the reasons why teachers do not use educational materials and equipment during their lessons. A literature study was done to investigate the factors which could contribute to resistance I the areas where resistance could appear and resistance of teachers to the use of media in their classrooms. An empirical study was conducted into the possible reasons for resistance to media usage at East Rand high schools. Research yielded the following results: The majority of teachers are willing to discuss media related matters with colleagues and superiors. Teachers are willing to experiment with a variety of media. The majority are willing to change their methods and use the ideas of others in their own classrooms.

M.Ed. / Students exhibit misconceptions or deviations from universally accepted concepts. Constructivists trace these misconceptions back' to the unique conceptual frames of reference of students. Ausubel (1985:82) named prior knowledge as the single most important factor influencing learning. New teaching strategies were designed to prevent or eliminate these misconceptions. The strategies are based on guidelines postulated by researchers such as Posner and his co-workers (1982:211). Several strategies use media to motivate students or provide a more concrete base for concept formation. The side effects of the utilization of media are important to designers and users of media. An empirical investigation was launched to determine whether media could also stimulate the formation of misconceptions. The investigation indicated that two dimensional representations of atoms, molecules and ion lattices can lead to misconceptions. Greater care should be taken in the selection of illustrations for textbooks and other media. If these side effects are taken into account by media designers and teachers, media can play a major role in the prevention and elimination of misconceptions.

In dieser Dissertation werden verschiedene Anforderungen an sicheres Cloud Computing untersucht. Insbesondere geht es dabei um die Analyse bestehender Forschungs- und Lösungsansätze zum Schutz von Daten und Prozessen in Cloud-Umgebungen und um die Bewertung ihrer Praxistauglichkeit. Die Basis für die Vergleichbarkeit stellen spezifizierte Kriterien dar, nach denen die untersuchten Technologien bewertet werden. Hauptziel dieser Arbeit ist zu zeigen, auf welche Weise technische Forschungsansätze verglichen werden können, um auf dieser Grundlage eine Bewertung ihrer Eignung in der Praxis zu ermöglichen. Hierzu werden zunächst relevante Teilbereiche der Cloud Computing Sicherheit aufgezeigt, deren Lösungsstrategien im Kontext der Arbeit diskutiert und State-of-the-Art Methoden evaluiert. Die Aussage zur Praxistauglichkeit ergibt sich dabei aus dem Verhältnis des potenziellen Nutzens zu den damit verbundene erwartenden Kosten. Der potenzielle Nutzen ist dabei als Zusammenführung der gebotenen Leistungsfähigkeit, Sicherheit und Funktionalität der untersuchten Technologie definiert. Zur objektiven Bewertung setzten sich diese drei Größen aus spezifizierten Kriterien zusammen, deren Informationen direkt aus den untersuchten Forschungsarbeiten stammen. Die zu erwartenden Kosten ergeben sich aus Kostenschlüsseln für Technologie, Betrieb und Entwicklung. In dieser Arbeit sollen die zugleich spezifizierten Evaluierungskriterien sowie die Konstellation der obig eingeführten Begriffe ausführlich erläutert und bewertet werden. Für die bessere Abschätzung der Eignung in der Praxis wird in der Arbeit eine angepasste SWOT-Analyse für die identifizierten relevanten Teilbereiche durchgeführt. Neben der Definition der Praktikabilitätsaussage, stellt dies die zweite Innovation dieser Arbeit dar. Das konkrete Ziel dieser Analyse ist es, die Vergleichbarkeit zwischen den Teilbereichen zu erhöhen und so die Strategieplanung zur Entwicklung sicherer Cloud Computing Lösungen zu verbessern.
