To successfully develop a system, a solid understanding of its architecture by stakeholders involved in the development of the system is key. This process is supported by System Architects, who have a profession that is often regarded as experience based. However, we argue that it is important to familiarize students with the concept of System Architecting, so that they are at least receptive of the nuances involved and potentially can continue a pathway of development towards such a role. In this paper we explore the potential use of A3 Architecture Overviews (A3AO) as an educational tool to support familiarization with Systems Engineering and Systems Architecting. The A3AO has been developed as a supportive tool to communicate a system’s architecture. It uses diagrams to model and visualize a system with different views and is intended to be printed on a physical A3 paper. It serves as a reference for, and facilitator of design discussions. Skills envisioned to be developed while using an A3AO include strict selection and visualization of information, two critical competencies to handle systems’ complexity. The A3AOs have been applied in a course on Systems Engineering at an applied University in The Netherlands and were part of the assessed deliverables. The relative free-form nature of the A3AO posed students with various dilemmas in their use, but also provided the opportunity for guided development on the envisioned competencies. We conclude that more research is required to further formalize this guided development, but we also experience that the A3AO has the potential to support systems engineering and systems architecting practices in education.
Abstract Although parental involvement is often a priority on the quality agenda of schools for primary and secondary education, it is still not usual to involve parents as an educational partner in the actual learning process of their child. Rather than adopting an open approach, teachers tend to tell parents what they should do or keep them at a safe distance. At the same time, parents are increasingly becoming better informed, more critical and thus are more strongly positioned towards school. They address teachers more directly in case of problems or disappointing results of their child. Clearly, this might lead to a negative impact on the mutual relationship especially when parents’ emotional involvement conflicts with a professional and detached attitude of teachers. Based on the results of several studies that provide ample evidence that parental involvement in the learning process can improve learning outcomes, it is argued that there is much to be gained in forming educational partnerships between parents and schools. Different dimensions of active parenting are discussed, as well as prerequisites for successful implementation
Background: Particulate matter (PM) exposure is an important health risk, both in daily life and in the workplace. It causes respiratory and cardiovascular diseases and results in 800,000 premature deaths per year worldwide. In earlier research, we assessed workers’ information needs regarding workplace PM exposure, the properties and effects of PM, and the rationale behind various means of protection. We also concluded that workers do not always receive appropriate risk communication tools with regards to PM, and that their PM knowledge appears to be fragmented and incomplete. Methods: We considered several concepts for use as an educational material based on evaluation criteria: ease of use, costs, appropriateness for target audiences and goals, interactivity, implementation issues, novelty, and speed. We decided to develop an educational folder, which can be used to inform employees about the properties, effects and prevention methods concerning PM. Furthermore, we decided on a test setup of a more interactive way of visualisation of exposure to PM by means of exposimeters. For the development of the folder, we based the information needs on our earlier mental models-based research. We adjusted the folder based on the results of ten semi-structured interviews evaluating its usability. Results: The semi-structured interviews yielded commentaries and suggestions for further improvement, which resulted in a number of alterations to the folder. However, in most cases the folder was deemed satisfactory. Conclusion: Based on this study, the folder we developed is suitable for a larger-scale experiment and a practical test. Further research is needed to investigate the efficacy of the folder and the application of the exposimeter in a PM risk communication system.
