Show moreThe aim of this research was to develop an effective, generative, and practical approach to enhance students’ structure-property reasoning (SPR). The approach consists of an evaluation instrument that assesses the level of structure-property reasoning and a teaching practice to make structure-property reasoning more explicit for students.As base of the approach, the perspective for SPR was used as model for structure-property reasoning. With this model, we aimed to represent the relationship between chemical concepts and the skill of structure-property reasoning.The SPR-instrument combines a sorting task with a mapping task based on the perspective for SPR. The instrument was tested on secondary school students and first-year chemistry students. The results showed that the SPR-instrument can discriminate between these two groups.This teaching practice consists of demonstration experiments with two design principles, namely the Predict-Observe-Explain (POE) approach and the perspective for SPR. The teaching practice was tested on Y-4 pre-university students. The results showed that the teaching practice contributed to the development of structure-property reasoning. The practicality of (re)designed demonstrations appeared to be as high as that of "traditional" demonstrations.The research showed that perspective for SPR (combined or not with POE-demonstrations) could bridge the gap in students’ chemical reasoning.

Show moreWork placement as a professional development programme for vocational teachers has been widely implemented. This dissertation provides insight into vocational teachers’ learning process in this programme within Chinese vocational education.Specifically, the first study generalised vocational teachers’ learning activities and outcomes in all various contexts with a systematic literature review, four categories of learning activities and eight types of learning outcomes were summarised. Then, the second study focused on vocational teachers’ motivational beliefs and engagement toward work placement. A quantitative analysis of questionnaire data displayed a significant relationship between them. Next, the third study utilised interviews to investigate vocational teachers’ learning activities, goals, and outcomes during work placement. The findings showed that vocational teachers employed seven categories of formal and informal activities in this programme and obtained many benefits about cognition, behaviour, emotion, and institution. The fourth and fifth studies both examined factors influencing vocational teachers’ transfer of learning from work placement to school practice. There were three categories of factors captured.The findings mentioned above contribute to a comprehensive understanding of vocational teachers’ professional learning in work placement. This will inspire policymakers, school leaders, and vocational teachers themselves to consider how to promote their learning in this programme. Show less

Show moreThe Vietnamese education system before 2013 struggled with many emerging issues, including achievement obsession, inflexible teaching strategies, student passivity, and cumbersome and lacking practice curriculum (see Le et al., 2022). Against that background, a comprehensive educational reform was initiated in 2013, emphasising students’ social and emotional learning and civic learning (Le et al., 2022). Vietnamese educational policymakers believe that promoting a democratic school environment would benefit students’ civic learning by empowering them to engage deeply in school decision-making (CPV, 2013; Ngo, 2015). Hence, the latest Education Reform in Vietnam focuses on promoting democracy in education which aims to make democratic acts of stakeholders (i.e., school leaders, teachers, students, and parents) feasible. The grassroots democracy regulation in Vietnamese schools requires decision-making based on consensus and deliberation of stakeholders (MOET, 2020). Thereby, the voice and leadership spirit of teachers and students in school affairs have been encouraged (Truong & Hallinger, 2017). Vietnam Ministry of Education and Training- MOET considers promoting a democratic learning environment as a fundamental mission in the latest educational reform in Vietnam. Yet, the policymakers still seem to squirm: what does a democratic school look like? How do we promote a democratic learning environment at the grassroots? As Gutmann (1987) has argued, democratic acts only occur when citizens can conceive the nature of the democracy they commit and pursue. However, the stakeholders in Vietnam have not been equipped with the necessary knowledge and skills to implement and reach democratic commitment in their schools (Mai & Hall, 2017; Thanh, 2017). Therefore, having insights into stakeholders’ democratic beliefs and democratic practices is essential to sketch and adjust the current education strategy of democratisation education in Vietnam. This dissertation aims to provide a critical view of Vietnamese secondary school stakeholders’ awareness of democratic education regarding the core educational democratic values and democratic acts within either the ‘physical’ or digital learning environment.

Show moreThis dissertation intended to examine how the multidimensionality of learner–learner interaction data and the multifacetedness of learner–learner interaction itself impact the measurement of learner–learner interaction in digital learning environments. The studies reported in this dissertation demonstrate that, on the one hand, the impact is reflected in the degree of variability with which learner–learner interaction is measured in research. The variability is determined both by the variety of the types of data on learner–learner interaction and by the variety of approaches that can be taken to the measurement of learner–learner interaction based on the different types of data. On the other hand, the impact is reflected in the intricacy with which the different aspects of learner–learner interaction, captured by the different approaches to the measurement of learner–learner interaction, interdepend in learning in digital learning environments. The studies, presented in this dissertation, taken collectively fulfil the triple function of (a) refining our understanding of learner–learner interaction; (b) guiding and improving our interpretation of research findings on learner–learner interaction; and (c) providing guidance and pointers for research and practice, together with identifying the potential pitfalls in researching learner–learner interaction.
