"Abstract. Sophisticated Technology Enhanced Learning (TEL) instruments as training simulations and Serious Games (SG) do not provide knowledge content in an explicit form, but propose interactive solutions for learners to build their own skills and competences in close to real situations. The present research makes an overview of the processes of knowledge transfer and content development in SG. In the first place, there will be analyzed and proposed methods how to elicit and embed expert knowledge into design of SG and training simulations. Therefore in the first place we will discuss the problem of expert knowledge elicitation for building SG. In the second place we will review how learning content can be integrated in SG design, and will identify various SG elements and components that can transfer knowledge to the players. Finally, some practical implications will be discussed, derived from the experience in TARGET FP7 EU funded project."

Abstract: "Out of the recent popularity of downloadable contents (DLC) among video game manufac- turers has resurfaced the issue of versioning of informatio n goods. The central idea behind the zero-day DLC strategy is that consumers who find the base v ersion of a game to be suffi- ciently attractive would pay a premium to upgrade by purchas ing such a DLC. In this work, we combine the literature on versioning with that on product sampling to model the impact of consumer learning on the product-line strategy of a game m anufacturer. In doing so, we demonstrate that a manufacturer's desire to vertically diff erentiate could actually stem from a horizontal separation among consumers. When consumers diff er in their perception of the fit between their tastes and the features of the product, horizo ntal differentiation seems a natural choice. However, if the manufacturer is unable to classify p otential consumers into groups with distinct tastes, horizontal differentiation becomes impra ctical. We find that, interestingly, this inability to differentiate horizontally does not limit the m anufacturer from vertically positioning its product line. We characterize the conditions under whic h the DLC strategy is effective and discuss how it affects consumer and social welfare. Our resul ts also have obvious implications in markets for other digital experience goods."

Abstract: "This paper describes the design and evaluation of Zoo U, a novel computer game to assess children's social skills development. Zoo U is an innovative product that combines theory-driven content and customized game mechanics. The game-like play creates the opportunity for stealth assessment, in which dynamic evidence of social skills is collected in real time and players' choices during gameplay provide the needed data. To ensure the development of an engaging and valid game, we utilized an iterative datadriven validation process in which the game was created, tested, revised based on student performance and feedback, and retested until game play was statistically matched to independent ratings of social skills. We first investigated whether the data collected through extensive logging of student actions provided information that could be used to improve the assessment. We found that detailed game logs of socially relevant player behavior combined with external measures of player social skills provided an efficient vector to incrementally improve the accuracy of the embedded assessments. Next, we investigated whether the game performance correlated with teachers' assessments of students' social skills competencies. An evaluation of the final game showed (a) significant correlations between in-game social skills assessments and independently obtained standard psychological assessments of the same students and (b) high levels of engagement and likeability for students. These findings support the use of the interactive and engaging computer game format for the stealth assessment of children's social skills. The created innovative design methodologies should prove useful in the design and improvement of computer games in education."
