Whereas blended learning can deliver several benefits to students in highereducation, their achievement depends on how exactly it is designed. A participatorydesign is recommendable to try to meet the needs of all stakeholders. ThePersuasive System Design-model can be used to motivate students during theonline part of the course. In the design there has to be an optimal blend betweenthe different parts of the course. A participatory design is used to design ablended learning course of autobiographical reflection for second year socialwork students. The blended course was developed in six meetings with aworking group, including all stakeholders (students, teachers, instructional designers,educational experts and professionals). Almost all techniques of the firstthree categories of the PSD-model were used in the design of the blended course.None of the techniques of the fourth category ‘Social Support’ of the PSD-modelwere used, mostly because they touch on the personal process of autobiographicalreflection. It was considered helpful for teachers to have a protocol thatassists them in blending the different parts and this in turn could stimulatestudents to be engaged in the different parts of the blended learning course. Inthis study, we found that the participatory design approach may lead to anengaging blended learning course that encourages the use of persuasive technologywith an optimal focus on content, target group, context and ethical aspectsof the blended course. We suggest adding a new fifth category ‘Blended LearningSupport’.What do you want to do ?New mail
Many students in secondary schools consider the sciences difficult and unattractive. This applies to physics in particular, a subject in which students attempt to learn and understand numerous theoretical concepts, often without much success. A case in point is the understanding of the concepts current, voltage and resistance in simple electric circuits. In response to these problems, reform initiatives in education strive for a change of the classroom culture, putting emphasis on more authentic contexts and student activities containing elements of inquiry. The challenge then becomes choosing and combining these elements in such a manner that they foster an understanding of theoretical concepts. In this article we reflect on data collected and analyzed from a series of 12 grade 9 physics lessons on simple electric circuits. Drawing from a theoretical framework based on individual (conceptual change based) and socio-cultural views on learning, instruction was designed addressing known conceptual problems and attempting to create a physics (research) culture in the classroom. As the success of the lessons was limited, the focus of the study became to understand which inherent characteristics of inquiry based instruction complicate the process of constructing conceptual understanding. From the analysis of the data collected during the enactment of the lessons three tensions emerged: the tension between open inquiry and student guidance, the tension between students developing their own ideas and getting to know accepted scientific theories, and the tension between fostering scientific interest as part of a scientific research culture and the task oriented school culture. An outlook will be given on the implications for science lessons.
Author supplied from the article: ABSTRACT Increasing global competition in manufacturing technology puts pressure on lead times for product design and production engineering. By the application of effective methods for systems engineering (engineering design), the development risks can be addressed in a structured manner to minimise chances of delay and guarantee timely market introduction. Concurrent design has proven to be effective in markets for high tech systems; the product and its manufacturing means are simultaneously developed starting at the product definition. Unfortunately, not many systems engineering methodologies do support development well in the early stage of the project where proof of concept is still under investigation. The number of practically applicable tools in this stage is even worse. Industry could use a systems engineering method that combines a structured risk approach, concurrent development, and especially enables application in the early stage of product and equipment design. The belief is that Axiomatic Design can provide with a solid foundation for this need. This paper proposes a ‘Constituent Roadmap of Product Design’, based on the axiomatic design methodology. It offers easy access to a broad range of users, experienced and inexperienced. First, it has the ability to evaluate if knowledge application to a design is relevant and complete. Secondly, it offers more detail within the satisfaction interval of the independence axiom. The constituent roadmap is based on recent work that discloses an analysis on information in axiomatic design. The analysis enables better differentiation on project progression in the conceptual stage of design. The constituent roadmap integrates axiomatic design and the methods that harmonise with it. Hence, it does not jeopardise the effectiveness of the methodology. An important feature is the check matrix, a low threshold interface that unlocks the methodology to a larger audience.
