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.

About this publication: In their new work research collective Ippolita provides a critical investigation of the inner workings of Facebook as a model for all commercial social networks. Facebook is an extraordinary platform that can generate large profit from the daily activities of its users. Facebook may appear to be a form of free entertainment and self-promotion but in reality its users are working for the development of a new type of market where they trade relationships. As users of social media we have willingly submitted to a vast social, economic and cultural experiment.By critically examining the theories of Californian right-libertarians, Ippolita show the thread con- necting Facebook to the European Pirate Parties, WikiLeaks and beyond. An important task today is to reverse the logic of radical transparency and apply it to the technologies we use on a daily basis. The algorithms used for online advertising by the new masters of the digital world – Facebook, Apple, Google and Amazon – are the same as those used by despotic governments for personalized repression. Ippolita argues we should not give in to the logic of conspiracy or paranoia instead we must seek to develop new ways of autonomous living in our networked society.

Research through design allows creating a dialogue with the material. It uses making andreflection on action as a generator of knowledge. Our aim is to explore the opportunities and challenges of smart textiles. The Fablab is our set up, a place that allows us to combine the hackingscientific-, and design community. It stimulates collaboration and the knowledge exchange needed for the development of smart textile systems. A collaborative prototyping workshop for medical products combined two worlds. The textile world in Saxion aims at incorporating conductive materials into textile structures and functional- / 3D printing to create systems for applications such as flexible heating systems and wearable technology. We combined this with the world of Industrial Design at TU/e, focused on the design of intelligent products, systems and services by the research through design approach. The collaboration between these different disciplines accelerated the process by reducing the resistance to the new and skipped the frustration on failure. Article from the Saxion Research Centre for Design and Technology published in the book 'Smart and Interactive Textile ' (pages 112-117), for the 4th International Conference Smart Materials, Structures and Systems, Montecatini Terme, Tuscany, Italy, 10th-14th June 2012.
