Systems thinking is a complex skill for learners in secondary education. We argue that qualitative representations can be valuable tools to actively engage in learning this skill. However, the effectiveness of these tools is currently hampered by complexity and the lack of instructional embedding. In this contribution, we present our developments on scaffolds for learning, instructional formats, and automated support in order to unleash the potential of qualitative representations for secondary education.

Much research has been done into the relationship between students’ motivation to learn and their basic psychological needs as defined by the self-determination theory (autonomy, competence, relatedness). However, few studies have explored how these psychological needs relate to different types of maladaptive behavior in the classroom. To prevent or remedy such behavior, more insight into its relationships is required. The present study attempted to determine the relationship between maladaptive behavior of secondary school students (grades 8 and 9) and the degree to which both teachers and peers address their needs for competence, autonomy, and relatedness. Results show significant, negative correlations between maladaptive student behavior in the classroom and the extent to which students’ basic psychological needs are met by teachers and fellow students. Both teachers and fellow students play a role in students’ maladaptive behavior toward school and withdrawn behavior. When it comes to unfriendly behavior, the perceived support of teachers appears to be particularly relevant, while the role of peers is an important factor in delinquent behavior.
This doctoral dissertation aims to address the challenges faced by physical education (PE) teachers in building an inclusive learning environment that promotes a physically active lifestyle among secondary school students. Although existing research offers useful empirical insights into addressing this complexity, successfully implementing these insights in the dynamic PE context remains challenging. It is recommended to develop tools that bridge the gap between theory and practice and provide guidelines for teachers to effectively embrace the diverse needs of students. Advancements in technology have created new opportunities for developing digital tools for CPD. In the field of PE, a variety of technologies (e.g., exergames, wearables) have been developed and are currently used. However, there is a scarcity of studies focusing on technology that primarily supports teachers in enhancing skills, knowledge, and expertise (i.e., CPD) rather than improving student learning. While the potential benefits of technological tools in PE have been recognized, their successful implementation remains complex. Therefore, this doctoral dissertation, grounded in the fields of social psychology, human-computer interaction (HCI), and design research, aims to (i) gain insights into the motivational perceptions and needs of students within secondary school PE, (ii) examine how the teacher can meet these motivational needs and (iii) explore how technology can be better utilized to support teachers in building an optimal motivational PE class climate. Therefore, the following research questions were formulated: 1. What are the differences and similarities in students’ motivational perceptions and needs in secondary school PE? 2. How can PE teachers meet the motivational needs of all students in secondary school PE? 3. What is the affordance of technology in supporting teachers in the PE context? The first study (chapter 2) focused on identifying distinct motivational profiles among secondary school students based on their perceptions of the PE environment. Building upon the first study, the second study (chapter 3) qualitatively examined students preferred motivational teaching strategies in secondary school PE. In our third study (chapter 4) we investigated the impact of potential motivating teaching strategies on students’ motivation in a secondary school PE context. These three studies yielded valuable insights into the motivational perceptions and needs of students in secondary school PE. It was demonstrated that students exhibit varied perceptions of the motivational climate in PE. However, despite these differences, it was discovered that students across different motivational profiles share similar motivational needs. Several teaching strategies within the dimensions of the TARGET framework were identified which are potentially beneficial for all secondary school students’ motivation. Yet, the implementation of these motivating TARGET teaching strategies in PE is challenging for teachers. Therefore, in the last two studies, we explored the affordance of technology in supporting teachers in the PE context. Study four (chapter 5) aimed to examine how the evidence-based theoretical TARGET framework for creating a motivating PE learning climate might be embedded into a digital professional development tool for PE teachers. A multidisciplinary team of researchers, designers, and end-users iteratively went through several phases of need identification, idea generation, designing, development, and testing. By using a participatory approach, the TARGET-tool for PE teachers was developed. In the fifth study (chapter six) we explored the applicability of the completed TARGET-tool in a secondary school PE context. The perceived usability of the tool was examined and we gained insights into the process of teachers’ professional development as a result of using the tool. In the last chapter (chapter 7), the main findings of the dissertation are discussed thematically in light of the overarching research questions and their empirical, methodological, and artefactual contributions. The three research questions are addressed to provide a comprehensive understanding of how to effectively support teachers in optimizing the motivational learning climate in secondary school PE and the potential facilitative role of technology in this process.

Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols. Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation. The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol. A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.

The impacts of tourism on destinations and the perceptions of local communities have been a major concern both for the industry and research in the past decades. However, tourism planning has been mainly focused on traditions that promote the increase of tourism without taking under consideration the wellbeing of both residents and visitors. To develop a more sustainable tourism model, the inclusion of local residents in tourism decision-making is vital. However, this is not always possible due to structural, economic and socio-cultural restrictions that residents face resulting to their disempowerment. This study aims to explore and interpret the formal processes around tourism decision-making and community empowerment in urban settings. The research proposes a comparative study of three urban destinations in Europe (The Hague in the Netherlands, San Sebastian in Spain and, Ioannina in Greece) that experience similar degree of tourism growth. The proposed study will use a design-based approach in order to understand tourism decision-making and what empowers or disempowers community participation within the destinations. Based on the findings of primary and secondary data, a community empowerment model will be applied in one the destinations as a pilot for resident engagement in tourism planning. The evaluation of the pilot will allow for an optimized model to be created with implications for tourism planning at a local level that can contribute to sustainable destinations that safeguard the interests of local residents and tourists.
