ACA-bot

ACA-bot is an engaging chatbot designed for Automated Conversational Assessment (ACA). Drawing inspiration from traditional oral exams, this text-based conversational agent transforms assessment into a dynamic learning experience. It supports both formative and summative evaluation by offering students personalised feedback and guidance at every step of their learning journey. The first ACA-bot prototype focuses on assessing students’ understanding of basic statistical concepts, but its flexible design allows for easy adaptation to a wide range of subjects and learning contexts. Through interactive dialogue, students can practise explaining ideas clearly under exam-like conditions, apply their knowledge to new and challenging questions, and refine their reasoning as they respond to follow-up prompts. They gain valuable insights into their own understanding, identify areas for improvement, and gradually build confidence for both oral and written assessments. For educators, ACA-bot offers a powerful way to scale oral examinations and enhance formative assessment without increasing workload. It automates parts of the assessment process, provides structured and actionable insights into student performance, and opens the door to more personal, interactive feedback at scale. By combining the strengths of conversational AI and educational assessment, ACA-bot turns evaluation into a collaborative, insightful process. It empowers students to think aloud, reason more effectively, and grow, while giving educators a smarter, more innovative way to understand and support learning. ACA-bot is een slimme en inspirerende chatbot die onderwijs en Artificial Intelligence samenbrengt. Geïnspireerd door het klassieke mondelinge examen tilt deze tekstgebaseerde gespreksagent Automated Conversational Assessment naar een nieuw niveau. Studenten krijgen via natuurlijke gesprekken directe, persoonlijke feedback en begeleiding, waardoor leren en toetsen samenvloeien in één boeiende ervaring. Het prototype van ACA-bot is ontwikkeld om kennis over statistiek te beoordelen, maar dankzij het flexibele ontwerp kan het systeem eenvoudig worden aangepast aan andere vakgebieden en toepassingen. Tijdens interactieve dialogen leren studenten helder uitleg geven, hun kennis toepassen op nieuwe vragen en hun redenering aanscherpen. Ze ontdekken waar hun begrip nog verdiept kan worden en groeien zichtbaar in zelfvertrouwen — waardevolle voorbereiding op zowel mondelinge als schriftelijke examens. Ook voor docenten biedt ACA-bot een slimme oplossing. Het maakt mondelinge toetsing schaalbaar, ondersteunt formatieve beoordeling via gesprek, en vermindert de werkdruk door delen van het beoordelingsproces te automatiseren.

Glass Sustainability: Reuse

In this video, Angelica Rota explains the concept and process of reusing architectural glass. Reusing glass panels or entire insulating glass units (IGUs) avoids the energy-intensive melting process of recycling, reducing CO2 emissions and preserving the material's quality. The process involves harvesting glass from buildings through selective deconstruction, followed by a complex disassembly to separate the glass from frames and spacers, and a critical quality assessment to sort the glass by its reuse potential. Despite its environmental benefits, glass reuse faces significant challenges. The disassembly of IGUs is complex and time-consuming, the logistics of handling large, brittle panels are difficult, and there is a lack of a strong market for secondary glass. Furthermore, collaboration across the supply chain, supportive regulations, and further research on issues like non-destructive quality testing are needed to make glass reuse a more viable and widespread practice. The video was produced by the Open GLASSroom project. Special thanks to Angelica Rota for contributing to the Open GLASSroom OER collection.

Glass Sustainability: Rethink

In this video, Angelica Rota explains the "Rethink" strategy for reducing the environmental impact of glass by moving from a linear to a circular economy. The video outlines two main approaches. The first is to rethink the supply chain by increasing the circularity of float glass, avoiding low-value downcycling, establishing systems to collect post-consumer glass waste, and preferring selective deconstruction over demolition. The second approach is to redesign glass products for disassembly, ensuring components like those in an insulating glass unit can be easily separated at end-of-life using reversible connections instead of permanent adhesives. While redesigning complex products presents challenges, these strategies are crucial for creating a sustainable, circular glass supply chain. The video was produced by the Open GLASSroom project.

Measure Sustainability: LCA

In this video, Angelica Rota explains the Life Cycle Assessment (LCA) methodology and its specific application to glass products. The LCA is a standardized process that evaluates a product's environmental impact from raw material extraction ("cradle") to final disposal ("grave"). The assessment follows four phases: defining the goal and scope, conducting a life cycle inventory, assessing the environmental impacts, and interpreting the results. For construction products like glass, the life cycle is divided into modules covering production, use, end-of-life, and potential benefits from recycling. The findings of an LCA are often published in an Environmental Product Declaration (EPD), a verified document that communicates transparent environmental data. For flat glass, the manufacturing stage is the most environmentally intensive, contributing the vast majority to its global warming potential due to the high energy required to melt raw materials. Increasing the use of recycled glass cullet is a key strategy for reducing this impact, as it significantly lowers the energy consumption and associated CO2 emissions of the melting process. Understanding LCA is crucial for identifying environmental hotspots and driving more sustainable practices in glass production and use. The video was produced by the Open GLASSroom project.

Introduction to Environmental Sustainability in Glass

In this video Rebecca Hartwell outlines the two key factors for sustainable glass design: material efficiency and energy efficiency. Material efficiency focuses on reducing the environmental impact from production to end-of-life, guided by the "9R framework". Energy efficiency concerns the glass's role in reducing a building's operational energy for heating, cooling, and lighting. The video explains that while advancements like double glazing and low-E coatings have improved energy efficiency, they often create complex, multi-material assemblies that are difficult to disassemble and recycle. Consequently, unlike container glass, most post-consumer flat glass is rarely recycled and is often downcycled or landfilled. A whole life-cycle perspective, balancing embodied and operational carbon, is essential for a sustainable glass future. The video was produced by the Open GLASSroom project.

An analysis of the current developments and scenarios for the transition to a fossil-free energy society this century

This century, greenhouse gas emissions such as carbon dioxide, methane, and nitrogen oxides must be significantly reduced. Greenhouse gases absorb and emit infrared radiation that contributes to global warming, which can lead to irreversible negative consequences for humans and the environment. Greenhouse gases are caused by the burning of fossil fuels such as crude oil, coal, and natural gas, but livestock farming and agriculture are also to blame. In addition, deforestation contributes to more greenhouse gases. Of the natural greenhouse gases, water vapor is the main cause of the greenhouse effect, accounting for 90%. The remaining 10% is caused from high to low by carbon dioxide, methane, nitrogen oxides, chlorofluorocarbons, and ozone. In addition, there are industrial greenhouse gases such as fluorinated hydrocarbons, sulphur hexafluoride, and nitrogen trifluoride that contribute to the greenhouse effect too. Greenhouse gases are a major cause of climate change, with far-reaching consequences for the welfare of humans and animals. In some regions, extreme weather events like rainfall are more common, while others are associated with more extreme heat waves and droughts. Sea level rise caused by melting ice and an increase in forest fires are undesirable effects of climate change. Countries in low-lying areas fear that sea level rise will force their populations to move to the higher-lying areas. Climate change is affecting the entire world. An estimated 30-40% o f the carbon dioxide released by the combustion of fossil fuels dissolves into the surface water, resulting in an increased concentration of hydrogen ions. This causes the seawater to become more acidic, resulting in a decreasing of carbonate ions. Carbonate ions are an important building block for forming and maintaining calcium carbonate structures of organisms such as oysters, mussels, sea urchins, shallow water corals, deep sea corals, and calcareous plankton.

Defects and Fracture Mechanics

In this video, Daniel Trias Mansilla explains the fundamental differences between brittle materials like glass and ductile materials like metals. While typically seen as brittle and fragile, glass has become a reliable structural material thanks to advancements in engineering and manufacturing. The key difference is that ductile materials can absorb energy through plastic deformation (bending without breaking), providing a safety warning before failure. In contrast, brittle materials like glass cannot deform plastically; they can only dissipate energy through crack growth. The strength of glass is not determined by its atomic bonds but by the presence of small defects like surface scratches, edge flaws, or inclusions. These defects cause a "stress singularity," where stresses become theoretically infinite at the tip of a sharp crack, making traditional stress analysis unreliable. The field of Fracture Mechanics is used to understand how cracks behave under different loading modes (I, II, and III) and to design and predict the load-bearing capability of glass. To improve strength, engineers must understand this relationship, and manufacturers must work to reduce the number and size of defects in the glass.

Transitioning towards a circular (healthcare) economy - BOOK

This book offers a comprehensive roadmap toward a circular and sustainable healthcare system, structured into three distinct parts. Part I describes circular principles and policy tactics. Chapter 1 outlines the essentials of sustainable healthcare and designates the paradox in daily practice of sustainability and the circular economy. In Chapter 2 the impact of leadership on policy together with best practices is discussed. The legislation and infrastructural web, in which many stakeholders and circular economy initiatives are strangled, is described. Despite the fact that politicians and policymakers are motivated to encourage sustainability, the infrastructure is designed to discourage circular economy projects. This chapter shows examples of setting-up intrinsic motivated teams of hospital staff, green teams, industry leaders and scientific motivated research teams. Swimming against the current is about the legislation paradox. In chapter 3 described as how legislation should be redesigned to accomplish the goals as set out in the green deal and the climate law. Part II serves as a practical guide to implementing circular strategies. In chapter 4 the reader is guided through the fundamentals of circular strategies by visualizing the circular economy. Chapter 5 reveals successful design strategies for products and processes which contribute to a zero-waste society. Using recycled materials by using waste as input for new products is described in chapter 6. In chapter 6 we will explore (surgical) waste as input for new products. Recycled should and could be used more. This is a fundamental concept within circular design principles but hardly used until this moment. Part III explores circular economy design principles on basis of successful examples. This part dives into real-world applications and measurable outcomes. It showcases successful circular design concepts and business models that have reshaped the market. Chapter 7: Is about leading by design. Success stories of circular concepts which have effectively changed the market with circular products and services are designated. Also entrepreneurial success stories of circular economy business models are presented. Chapter 8 investigates how to measuring effectiveness and impact of circular economy products and processes. In particular how reliable some facts are which are used by many to sell products or introduce new policies or legislation. How trustworthy is data from life cycle assessments (LCA’s)? What are the pitfalls? Is it possible to manipulate these data? Why should we characterize one-sided data from an LCA as greenwashing? Circular Economy principles, sustainability and, in broader sense, the climate discussion seem to trigger emotions. Using fundamental and reliable data is essential in order to be able to judge whether a product or process indeed reduces CO2 emissions is essential in decision-making. Chapter 9 focusses on how universities can contribute to sustainable solutions by presenting different cases which resulted in actual results which were implemented or are ready for upscaling. The role of universities as innovation hubs is highlighted through case studies with proven impact. The final chapter offers a reflective and forward-looking analysis on how circular strategies in healthcare can shape future societal developments. The authors reflect on the content in chapter 10. A final part in which a critical analysis is presented and the impact it could have on future developments and the society.
