Over the past decade, the maker movement and in its slipstream maker education have attained worldwide popularity among educators, politicians, and the media. Makers’ enthusiasm for creative design and construction, using old and new tools has proven contagious, and is worth exploration and critical reflection by the community of engineering and technology education (ETE). This chapter describes what has been said about “making” by philosophers and educators; what maker education is, and what is new and not so new about it; why it has gained momentum; what the evidence is about its effectiveness and its possible weaknesses; and how mainstream technology education may benefit from maker education. This chapter concludes with ideas for a research agenda.

Purpose: In long-track speed skating, drafting is a commonly used phenomenon in training; however, it is not allowed in time-trial races. In speed skating, limited research is available on the physical and psychological impact of drafting. The aim of this study was to determine the influence of “skating alone,” “leading,” or “drafting” on physical intensity (heart rate and blood lactate) and perceived intensity (perceived exertion) of speed skaters. Methods: Twenty-two national-level long-track speed skaters with a mean age of 19.3 (2.6) years skated 5 laps, with similar external intensity in 3 different conditions: skating alone, leading, or drafting. Repeated-measures analysis of variance showed differences between the 3 conditions, heart rate (F2,36 = 10.546, P < .001), lactate (F2,36 = 12.711, P < .001), and rating of perceived exertion (F2,36 = 5.759, P < .01). Results: Heart rate and lactate concentration were significantly lower (P < .001) when drafting compared with leading (heart rate Δ = 7 [8] beats·min–1, 4.0% [4.7%]; lactate Δ = 2.3 [2.3] mmol/L, 28.2% [29.9%]) or skating alone (heart rate Δ = 8 [7.1] beats·min–1, 4.6% [3.9%]; lactate Δ = 2.8 [2.5] mmol/L, 33.6% [23.6%]). Rating of perceived exertion was significantly lower (P < .01) when drafting (Δ = 0.8 [1.0], 16.5% [20.9%]) or leading (Δ = 0.5 [0.9], 7.7% [20.5%]) versus skating alone. Conclusions: With similar external intensity, physical intensity, as well as perceived intensity, is reduced when drafting in comparison with skating alone. A key finding of this study is the psychological effect: Skating alone was shown to be more demanding than leading, whereas leading and drafting were perceived to be similar in terms of perceived exertion. Knowledge about the reduction of internal intensity for a drafting skater compared with leading or skating alone can be used by coaches and trainers to optimize training conditions.

Scheepvaart, landbouw, zand- en kleiwinning hebben, naast hoogwaterveiligheid, eeuwenlang de inrichting en het beheer van het rivierengebied bepaald. In de jaren tachtig van de vorige eeuw (her)ontdekte men het natuurpotentieel van het rivierengebied. Ook voor wonen en recreatie richtte men de aandacht op het rivierengebied. Het werd gecompliceerd toen de eerste effecten van de klimaatverandering zichtbaar werden met de extreme hoogwaters van 1993 en 1995. Het verenigen van alle ruimteclaims bleek geen eenvoudige opgave. Er werd naarstig gezocht naar modellen waarbij ook regionale en lokale partijen hunsteentje zouden bijdragen aan de gewenste functiecombinaties. Sindsdien is de behoefte aan co-creatie in het rivierengebied alleen nog maar groter geworden. Hoe is het eigenlijk met die experimenten afgelopen? En welke stappen worden nu ondernomen om co-creatie in het rivierengebied verder te optimaliseren?

The implementation of the new mathematical knowledge base in Dutch teacher education institutes for primary education raises a need for curriculum development. Teacher educators have to raise student teachers’ subject matter knowledge to a higher level. In working on this aim teacher educators experience that student teachers often feel uncertain about their mathematical skills and are not very interested in formal and abstract mathematics. Student teachers prefer to focus on mathematical pedagogical content knowledge. This paper presents two design studies that try to tackle this problem. The first one targets the development of student teachers’ specialized content knowledge (SCK) and the second one focuses on their horizon content knowledge (HCK). Both studies target developing student teachers’ mathematical subject matter knowledge in the perspective of teaching mathematics in primary school. In the studies we established student teachers’ learning environments that kept them involved and motivated, even when they found the mathematics hard to do. Primarily, this attitude supported their mathematical growth, while it also developed their pedagogical skills and insight. INTRODUCTION

Europese landen worstelen met het ‘post Snowden’-tijdperk. Dit is zichtbaar in de nieuwe wetgeving die in veel landen recentelijk tot stand is gekomen. Grote thema’s daarbij zijn onder meer hoe om te gaan met de hedendaagse informatiesamenleving, die oneindige hoeveelheden data produceert en die zich kenmerkt door snelle technologische ontwikkelingen. Hoe kan worden voorkomen dat zich een tweede ‘Snowden’-onthulling gaat voordoen? Ook de Wet op de inlichtingen- en veiligheidsdiensten (Wiv) 2017 is opnieuw een product van zijn tijd. Deze wet probeert de nieuwe dilemma’s te ondervangen terwijl tegelijkertijd een werkbare situatie voor de bescherming van de rechtstaat via inlichtingen en veiligheidsdiensten wordt nagestreefd. Wij presenteren in dit artikel een aantal kanttekeningen bij de Wiv 2017. Dit doen wij door een aantal relevante in Nederland (Eskens e.a. 2016; Loof e.a. 2016) en in de Europese Unie1 verschenen overkoepelende studies over grondrechten te bespreken. Deze kanttekeningen zijn deels gebaseerd op normatieve uitgangspunten en aanbevelingen uit deze studies, deels ontleend aan nog lopend onderzoek. Gezien de aard en omvang van dit artikel is een selectie gemaakt en beperkt de analyse zich tot het schetsen van de belangrijkste dilemma’s.

Twitter timelines are increasingly populated with brand tweets that are linked to public events, a practice that is also known as real-time marketing (RTM). In two studies, we examine whether RTM is an effective strategy to boost sharing behavior, and if so, what event- and content-related characteristics are likely to contribute to its effectiveness. A content analysis of brand tweets from Nielsen’s top-100 advertisers (n=1500) shows that not all events are equally effective. RTM is only a more effective strategy (vs. no real-time marketing), when brand messages are linked with unpredictable events but not when brand messages are linked with predictable events. In a follow-up study, we examined what content characteristics improve the shareability of predictable RTM messages. A content analysis of RTM messages (n=143) from the Forbes top-100 brands showed that predictable events yield more retweets when the event is visually integrated in the brand tweet (vs. not visually integrated). The presence of event-driven hashtags did not lead to more retweets. Implications for theory and practice are discussed.

Over recent years aspects of sustainability have claimed a central role in many countries. As a result research for sustainability has become an important driver for innovation. This paper describes developing a model that supports SMEs in integrating sustainability in their business and innovation processes. In general innovation and entrepreneurship are important in the realm of national economies because they hold the key to the continuity and growth of companies and economic growth within a country. National governments are spending vast sums of money to enable and improve innovation management and entrepreneurial behaviour within organizations. This is also the case in The Netherlands. Partnerships involving universities (education), companies (preferably SMEs) and industrial associations (business) and representatives from governmental organizations (community) are stimulated and should be geared towards: the development of sustainable networks, a contribution to regional economic growth within sectors, the development of learning communities in which best practices are shared, knowledge circulates and knowledge is created through applied research and last but not least sustainable relations are developed between universities and the business community. Within the centre for innovation and entrepreneurship at our university we have taken the initiative to develop an innovation programme for entrepreneurs in the construction industry to help them integrate sustainability in their business processes, while simultaneously professionalizing students and teachers. Sustainability and concern for the environment are two of the main reasons for entrepreneurs to look for opportunities to innovate. Policy measures are aimed at reduction of CO2 emission, waste management and alternative use of energy sources and materials. In line with these measures companies are urged to integrate sustainability in their business processes and search for innovative sustainable solutions. This paper describes the experiences with a number of SMEs in the construction industry and the barriers entrepreneurs encounter on the road towards sustainability. We focus on the role of the entrepreneur in the process of sustainable innovation and development. We conducted exploratory research and through an organisational analysis and in-depth interviews with the owners/managers of the companies insight was gained in innovation processes towards sustainable development. Conclusions show that one of the main bottlenecks is the dilemma posed by the need for profit for the continuity of a company, while taking into account people and planet. The dilemmas of innovation are described as issues that need to be addressed and which influence the innovative capacity of companies and organizations. This paper deals with the underlying factors related to the dilemma between sustainability and growth/profit.

We maken op grote schaal steeds meer gebruik van digitale middelen en mogelijkheden in het onderwijs; de leeromgeving is digitaal, we toetsen digitaal, we communiceren digitaal en we ontwikkelen steeds meer digitale lesmaterialen. Kortom: onderwijs digitaliseert. Met de toename van digitale lesmaterialen, is er een groeiende beweging om deze materialen voor iedereen toegankelijk te maken; dus niet alleen voor de eigen studenten of binnen de eigen instelling. Deze vrije toegang tot kennisproducten c.q. leermaterialen is versterkt door de Open Access beweging. De Open Access beweging stimuleer het vrij aanbieden van publicaties voor onderzoek en tevens het vrij aanbieden van o.a. leermaterialen voor het onderwijs. De Open Access beweging is al enkele decennia oud. We zien echter dat de “open-gedachte” nog geen gemeengoed is. Dit geldt zeker voor het onderwijs waarbij het gaat om het delen en hergebruiken van open leermaterialen. Open Leermaterialen, of Open Educational Resources (OER), zijn onderwijs-, leer- en onderzoeksmaterialen die digitaal of analoog vrij beschikbaar en herbruikbaar zijn voor iedereen. Om te weten of het materiaal vrij beschikbaar en herbruikbaar is, staat er een open licentie op. Deze licentie geeft aan hoe iemand de leermaterialen mag (her)gebruiken, wijzigen en (opnieuw) delen. Aan welke type (open) leermaterialen kun je denken? Dat zijn materialen zoals: tekst, beeld, audio, games, simulaties, presentaties, 3Dmodellen, websites, data, e.a..

Since the film of Al Gore An inconvenient truth, sustainability stands high on the national agenda of most countries. Concern for the environment is one of the main reasons in combination with opportunities to innovate. In general, innovation and entrepreneurship are important in the realm of national economies because they hold the key to the continuity and growth of companies (e.g. Hage, 1999; Cooper, 1987; Van de Ven, 2007) and economic growth within a country. It is therefore obvious that national governments are investing money to enable and improve innovation management and entrepreneurial behaviour within organizations with sustainability in mind. Policy measures are aimed at reduction of carbon dioxide emission, waste management and alternative use of energy sources and materials. In line with these measures companies are urged to integrate sustainability in their business processes and search for innovative sustainable solutions. While on a national level policy measures towards a more sustainable society are defined, enterprises - and especially small and medium sized companies - lag behind and fail in incorporating these measures appropriately in their day-to day business. As a result research for sustainability has become an important driver for innovation. Within the Centre for Innovation and Entrepreneurship (CI&E) at The Hague University of Applied Sciences we have taken the initiative to develop an innovation and research program for the construction industry to help small and medium sized companies (SME's) integrate sustainability in their business processes, while simultaneously professionalizing students and lecturers. This paper is part of ongoing research among 40 companies in the region of South-Holland. The companies are mostly SME's varying from very small (6 employees) to middle-sized (more than 100). According to Rennings (2000) while innovation processes toward sustainable development have received increasing attention during the past years, theoretical and methodological approaches to analyse these processes are poorly developed. This paper describes a theoretical approach developed at our university's Centre for Innovation and Entrepreneurship, which combines education and research. It is an inductive approach that departs from real-life problems encountered by companies, and is aimed at developing a model that supports companies in integrating sustainability in their business and innovation processes. We describe the experiences so far with a number of companies in the construction industry, which participate in the innovation and research program described above and the barriers they encounter. Our sustainable program is centred on four themes: cradle-to-cradle, social corporate responsibility, climateneutral construction and sustainability and customer orientation in the building process. It is an exploratory research in which students and undergraduates are involved under the supervision of a lecturer as senior researcher of this program. Through an in-depth analysis of the companies, participant observation and indepth interviews with the owners/directors of the companies, experts and prominent sustainable trendsetters, insight is gained in innovation processes towards sustainable development. Preliminary conclusions show that on a company level one of the main bottlenecks is the dilemma posed by the need for profit for the continuity of a company, while taking into account people and planet. The main bottleneck is however the inability of companies to translate policy measures into strategy and operations. This paper is set up as follows. In section 2 we give an account of European and Dutch policy measures geared at stimulating sustainability in a business context and especially the building and construction industry. In section 3 an overview is given of the economic importance and characteristics of the Dutch building and construction industry and the problems in this sector. These problems are offset against the opportunity of sustainability as a strategic option for SME's in this sector. In section 4 the innovation and research program developed at the CI&E is introduced in the context of the main research question. Following that in section 5, methodological choices are addressed and the research design is presented. We finalize this paper in section 6 with our conclusions and recommendations for further research.
