This thesis is entitled “Fostering collective teacher efficacy through values-based leadership in Ethiopian institutions of higher education”, which is delimited to the private universities. The main question was “What constitutes/determines the institutionalisation of values-based leadership (VBL) to foster collective teacher efficacy (CTE) in the context of Ethiopian private universities (EPrUs)?” The sub-questions were: 1) what does the current state of CTE and its perceived outcomes look like in EPrUs? 2) What sets of behaviours are desired to institutionalise VBL so as to foster CTE in EPrUs? 3) What are the institutional contexts required to institutionalise VBL so as to foster CTE in EPrUs? In addressing these issues, academic leaders, students and teachers from EPrUs participated in the study. As methods of data gathering both the survey method and interviews were used. Results revealed that CTE is not high enough in EPrUs and hence it needs to be fostered so as to bring the desired change in students’ learning. To foster this, institutionalisation of VBL is required that involves two inter-related aspects. The first one is about institutionalising desired values (behaviours), which are linked to the academic leaders’ yearning for positive sets of values and the teachers’ moral contract to their professional values. To this effect, the positive sets of values that academic leaders should yearn for and the sets of values that teachers should espouse as their professional values are explored. The commonalities between these values are also described and how these would be institutionalised is suggested. The values include integrity and trustworthiness, humility/selflessness, compassion and sense of gratitude, accountability and self-discipline, sense of collaboration and teamwork, and envisioning in leadership as the driving force. The second aspect is about institutionalising the contexts conducive to foster CTE and VBL support behaviours. The need to institutionalise those behaviours and contexts arise out of the perceived leadership gap (between what the teachers believe are the leadership priorities of the leaders and the behaviours they actually see in the leaders). This gap has been linked to CTE, and hence a model has been developed that would foster this efficacy. / Educational Leadership and Management / D. Ed. (Educational Management)

<p>Professional engineers think and act in distinctive ways when addressing engineering problems. Students need to develop this reasoning or engineering thinking during their education. Unfolding the undergraduate students’ thinking is a necessary step in designing experiences and teaching materials that foster not only their understanding of engineering concepts but also their learning to think as professional engineers. While there are previous studies about the students' thinking in other disciplines, more research is needed in engineering. This three-study dissertation aims to further our comprehension of undergraduate students’ engineering thinking using an adapted version of the Engineering Habits of Mind (EHoM) model. Specifically, the dissertation’s studies work together to continue the research that addresses the question:<em> What are the characteristics of undergraduate students</em>’ <em>engineering thinking?</em></p> <p><br></p> <p>The first study used naturalistic inquiry to holistically explore the cognition associated with the EHoM of senior chemical engineering students when improving a chemical plant. The analysis of students’ interactions showed that their redesign process followed an iterative co-evolution of the problem and solution spaces. Furthermore, they treated the task as a socio-technical problem considering engineering and non-engineering factors. In addition, while exploring problem and solution entities, they used multiple representations to communicate ideas but had difficulties translating symbolic representations into more physical, concrete representations. Regardless the technical issues and time constraints, the students completed the conceptual redesign and communicated their proposal to the client.</p> <p><br></p> <p>The second study used qualitative content analysis to examine first-year engineering students’ ideation as a cognitive skill associated with the EHoM of problem finding and creative problem solving. Particularly, it focused on students’ ideation of questions and recommendations when doing data analytics to help improve a client’s enterprise. The analysis of students’ reports showed that they expanded the problem space of the task by bringing additional information that was not provided. They asked questions focused on performing statistical analysis of the dataset and requesting information about the company’s business model. At the end of their data analytics, students made high- and low-quality recommendations considering their alignment with a specific problem, robust evidence, and the client’s needs. </p> <p><br></p> <p>The third study used qualitative descriptive research to investigate undergraduate participants' cognitive competencies within engineering systems thinking at the International Genetically Engineered Machine (iGEM) competition. These competencies are associated with the EHoM of problem finding, creative problem solving, systems thinking, and visualization. Mainly, the study focused on analyzing the evidence of cognitive competencies documented in the publicly available participants’ wikis where they registered their design process. Results showed that iGEM teams developed solutions with biological systems interacting with other systems and used concepts and tools from multiple disciplines. They also cooperated with stakeholders, which helped them analyze their system from multiple lenses. Moreover, depending on their upfront task, they fluidly represented their systems from structural, behavioral, and functional perspectives. </p> <p><br></p> <p>The final chapter of this dissertation presents an overarching discussion across the studies. The findings and implications will support curriculum designers, instructors, and other interested readers to prepare learning environments that promote undergraduate students’ engineering thinking. Furthermore, they may guide future efforts to continue exploring the students' thinking process when addressing engineering problems. </p>
