A study of the relation between teachers’ pedagogical content knowledge of reading and the quality of their subsequent classroom behaviour in teaching fluent reading.
For further development of technologies but also for the implementation in real life contexts, it is important to understand users' perspectives on the anticipated use of innovative technologies in an early development phase. In addition, it is also important to get a better understanding of the explanation of this behavior towards technology use in later stages. Although Head Mounted Displays (HMDs) are not really new anymore, the uptake has been slow so far and people showed some extreme reactions. The objective of this study was to analyze the content of YouTube comments on videos of HMDs, in order to get a better understanding of relevant factors in this early phase of potential acceptance of HMDs. We analyzed 379 YouTube comments on HMDs using content analysis. Comments were divided into three groups: HMD, video, and miscellaneous. Comments about HMDs n=24 were further analyzed. Most of the commenters showed a positive attitude to HMDs. Within the positive attitude, the most expressed themes were comments about the type of use (gaming), positive evaluations (emotions, coolness) and perceived need for an HMD. Within the negative attitudes, negative evaluations (judgments, emotions) were showed most and negative comparisons to other products were made. In neutral attitudes, the main theme was the type of use (gaming). The results specify a couple of user needs and social norms and values which people attach in this early phase to HMDs. In this early phase of acceptance, some early adoption observations were found as in when someone talks about the type of use (felt needs) and positive judgments (social norms). Early signs of rejection were found by negative judgments (social norms) and comparisons with other products (previous practice).
Serious games foster the acquisition of complex problem-solving skills. Assessment of such skills should be in line with instruction, and within a serious game environment its content validity should equal face-to-face assessment. Research on assessment in serious gaming has remained rather scarce. This article shows how assessment can be implemented in serious gaming in a way that assures content validity. The core of the authors’ validation method entails mapping learning activities (as contained in the game scenario) on performance indicators and outputs (as derived from formal attainment levels). They present how they have elaborated and applied the method for an assessment game for ICT managers in secondary vocational education. They describe the procedure and extent to which this assessment is content-valid compared to face-to-face assessment.

The production of denim makes a significant contribution to the environmental impact of the textile industry. The use of mechanically recycled fibers is proven to lower this environmental impact. MUD jeans produce denim using a mixture of virgin and mechanically recycled fibers and has the goal to produce denim with 100% post-consumer textile by 2020. However, denim fabric with 100% mechanically recycled fibers has insufficient mechanical properties. The goal of this project is to investigate the possibilities to increase the content of recycled post-consumer textile fibers in denim products using innovative recycling process technologies.
Carboxylated cellulose is an important product on the market, and one of the most well-known examples is carboxymethylcellulose (CMC). However, CMC is prepared by modification of cellulose with the extremely hazardous compound monochloracetic acid. In this project, we want to make a carboxylated cellulose that is a functional equivalent for CMC using a greener process with renewable raw materials derived from levulinic acid. Processes to achieve cellulose with a low and a high carboxylation degree will be designed.
Deze aanvraag onderzoekt hoe de beta-versie van de Dynamische Arousal-Valence Tool - ontwikkeld binnen SIA-RAAK’s Network is the Message – naar de markt gebracht kan worden. De DAVTool meet sentiment in social media posts. Sentimentanalyse levert cruciale informatie voor social media managers, online marketeers en content strategen. Zij móeten weten wat het sentiment over hun product, bedrijf of dienst is om adequaat te kunnen interveniëren. De huidige manier van meten levert niet voldoende inzicht. De nieuwe DAVTool vult de meting aan en meet sentiment op een innovatieve manier en geeft als gevolg meer en betere informatie.
