Identifying, examining, and understanding faculty members’ technological knowledge development and the process of technology adoption in higher education is a multifaceted process. Past studies have used Rogers (1995, 2003) diffusion of innovation theoretical framework to delineate the technology adoption process. These studies, however, have frequently reported the influencing factors based on the statistical analysis such as regression analysis-based approach, and have not focused on the emerging process of technology adoptions or the developing process of technological knowledge and pedagogical knowledge. A mixed method study was designed to see how faculty members acquire different technologies and develop technological knowledge that might help them adopt technologies in their classrooms and online using different pedagogies. A sample of STEM teaching faculty members with different ranks, tenure, teaching experience, and varied degree of experience in the use of educational technologies participated in the study. A survey was designed to identify internal and external factors affecting technology adoption and its effective use in different teaching activities. To elaborate survey results, the study also included class observations as well as pre- and post-observation interviews. Online classrooms used by the faculty via Blackboard learning management system, online flipped classrooms, or other websites such as Piazza were also examined for data triangulation. The findings of the study indicate that faculty members are influenced by their own professional motivations and student learning to improve their teaching methods and to enhance student interactions and learning through the use of different educational technologies. The adoption process was identified as spreading over a period of time and it looked at how faculty members’ developed their technological knowledge and pedagogical knowledge. With the recognition of the social, organizational, and professional motivational factors both expert faculty members, university administrators, and technologist could be made aware of the critical components necessary to construct and support a bottom-up or user-centric successful innovation adoption decision process. The bottom-up approach would use expert professors as change agents and educational designers that would encourage exchanges and meaningful dialogues about educational technology adoptions and effective uses of technology with pedagogy within each discipline and department.

Este setor tem ganhado relevância conforme aumentam seu leque de produtos e a demanda por estes e conforme ele consolida-se como parcela crescente da matriz energética do país. Tendo estas perspectivas em vista, grandes esforços de pesquisa têm sido despendidos focados nas necessidades e potenciais do setor. Uma vez que estes esforços resultem em inovações, será relevante entender a dinâmica e os determinantes da difusão de inovações na agroindústria canavieira. Neste contexto, propõe-se elaborar e utilizar um modelo de simulação baseado em agentes para organizar, explicitar e testar hipóteses acerca dos determinantes do processo de difusão de nova tecnologia de extração de sacarose. Observa-se a competição entre duas tecnologias alternativas, uma baseada em ternos de moendas e outra baseada em difusores. A primeira, disponível há séculos, mantém-se, no período estudado, dominante sobre a segunda, adaptada da produção de açúcar de beterraba há poucas décadas. Pretende-se, com este estudo, contribuir ao entendimento dos determinantes do processo de difusão de tecnologias no setor. Os resultados obtidos pela simulação indicam que as hipóteses não foram capazes de replicar o fenômeno observado. Isso se mostra útil ao objetivo final da pesquisa conduzida, tendo em vista que o conhecimento adquirido no desenvolvimento do modelo e no estudo de seus resultados foi relevante no balizamento de estudos futuros para aprimorar essas hipóteses. A principal direção apontada pelos resultados é para o estudo da estrutura de modularidade do processo produtivo e de seu impacto nos processos de difusão de tecnologia na agroindústria canavieira / Abstract: This study relates to the question of the diffusion technologies in the sugar-cane agroindustry. This sector gains relevance as its range of products increases, its demands grows and it settles as a relevant part of the national energy sources. With this in sight, there have been great research efforts aiming at the needs and potentials of this sector. Once these efforts result in innovations, it will be relevant to understand the dynamics and determinants of innovation diffusion in sugar-cane agroindustry. In this context, the development and use of an agent-based simulation model as a tool for organizing, explicitly stating and testing hypothesis about the determinants of the diffusion process of new technology of sucrose extraction is proposed. The competition between two technologies, one based on press rolls and the other on diffusers, is observed. The first, available for centuries, holds, throughout the studied period, dominant over the second, adapted from the beetroot sugar production a few decades ago. This study aims, with this, at contributing to the understanding of the determinants of the process of diffusion of technologies in this sector. The results obtained from the simulations show that the hypothesis was not enough to replicate the observed phenomena. This proves useful to the established aim of this research, given that the knowledge developed by the building of the model and the analysis of its results was relevant in the identification of good future research on diffusion of technologies in the sector. The main path to be studied shown by the results of this research is the modularity structure of the production process and its impact on the diffusion of new technologies processes on the sugar-cane agroindustry / Mestrado / Ciências Economicas / Mestre em Ciências Econômicas
