Learning in a game-based virtual environment: a comparative evaluation in higher education

The authors define the requirements and a conceptual model for comparative evaluation research of simulation games and serious games (SGs) in a learning context. A first operationalisation of the model was used to comparatively evaluate a suite of 14 SGs on varying topics played between 2004 and 2009 in 13 institutes of higher education in the Netherlands. The questions in this research were: what is the perceived learning effectiveness of the games and what factors explain it? How can we comparatively evaluate games for learning? Data were gathered through pre- and post-game questionnaires among 1000 students, leading to 500 useful datasets and 230 complete datasets for analysis (factor analysis, scaling, t-test and correlation analysis) to give an explorative, structural model. The findings are discussed and a number of propositions for further research are formulated. The conclusion of the analysis is that the students’ motivation and attitudes towards game-based learning before the game, their actual enjoyment, their efforts during the game and the quality of the facilitator/teacher are most strongly correlated with their learning satisfaction. The degree to which the experiences during the game were translated back into the underlying theories significantly determines the students’ learning satisfaction. The quality of the virtual game environment did not matter so much. The authors reflect upon the general methodology used and offer suggestions for further research and development.     

Evaluating instructional software: A review and critique of current methods

The purpose of this paper is to discuss the key features of various methods that software evaluation organizations employ to evaluate instructional software. Who conducts the evaluations, the processes they use for doing so, and the software features they evaluate are among the topics that are discussed. Some of the problems associated with many of the evaluation methods are also described, as is an alternate method designed to overcome some of the identified problems. Special emphasis is placed on the role of students as participants in the evaluation process, and the benefits that may be derived from placing students in that role.     

Overshadowing of environmental cues by an odor in toxicosis-based conditioning in rats

It was demonstrated that an odor presented to rats in a distinctive environment can interfere with toxicosis-based conditioning to the environmental cues. Rats poisoned when they drank unflavored water in a black compartment odorized with oil of eucalyptus exhibited no suppression of water intake when they were subsequently tested in the same compartment minus the odor. In contrast, rats poisoned in the same compartment minus the odor later exhibited reduced water consumption in that environment. Oil of eucalyptus proved to be as effective an overshadowing stimulus as a taste cue (a 1.5% NaCl solution).     

Motorische Basiskompetenzen in der Grundschule

For the establishment of empirical educational research in sport, valid survey instruments are necessary for assessing the disposition to motor performance. One approach is the assessment of basic motor competence, which is theoretically justified for competence as a central educational target of physical education and defines the scope of motor abilities and skills.     

Phonological Awareness and Rapid Automatized Naming as Longitudinal Predictors of Reading in Five Alphabetic Orthographies with Varying Degrees of Consistency

ABSTRACT

Although phonological awareness (PA) and rapid automatized naming (RAN) are confirmed as early predictors of reading in a large number of orthographies, it is as yet unclear whether the predictive patterns are universal or language specific. This was examined in a longitudinal study across Grades 1 and 2 with 1,120 children acquiring one of five alphabetic orthographies with different degrees of orthographic complexity (English, French, German, Dutch, and Greek). Path analyses revealed that a universal model could not be confirmed. When we specified the best-fitting model separately for each language, RAN was a consistent predictor of reading fluency in all orthographies, whereas the association between PA and reading was complex and mostly interactive. We conclude that RAN taps into a language-universal cognitive mechanism that is involved in reading alphabetic orthographies (independent of complexity), whereas the PA–reading relationship depends on many factors like task characteristics, developmental status, and orthographic complexity.     

Computational approaches for mining user’s opinions on the Web 2.0

The emerging research area of opinion mining deals with computational methods in order to find, extract and systematically analyze people’s opinions, attitudes and emotions towards certain topics. While providing interesting market research information, the user generated content existing on the Web 2.0 presents numerous challenges regarding systematic analysis, the differences and unique characteristics of the various social media channels being one of them. This article reports on the determination of such particularities, and deduces their impact on text preprocessing and opinion mining algorithms. The effectiveness of different algorithms is evaluated in order to determine their applicability to the various social media channels. Our research shows that text preprocessing algorithms are mandatory for mining opinions on the Web 2.0 and that part of these algorithms are sensitive to errors and mistakes contained in the user generated content.     

Two factors of expertise? Excellence and professionalism of environmental experts

The aim of this article is to empirically clarify factors and conditions of expertise. In addition to the core concept of expertise as excellence, a second factor needs to be taken into account: professionalism, or professional engagement. This hypothesis was tested and confirmed using data obtained from a survey on Swiss environmental professionals (n = 3514). The empirical test was based on factor analyses (Study 1) and a structural equation model (Study 2). The expertise scale consisted of nine items for self‐assessed perceived expertise amongst professional peers (α = .78). Excellence turned out to be a logarithmic function of years of practice (Study 3). Professionalism prevailed in domains where standards for best practices still needed to be established (Study 4).     

Disaster,civil society and education in China: A case study of an independent non-government organization working in the aftermath of the Wenchuan earthquake

In May 2008 nearly 90,000 people died in the most powerful earthquake in modern Chinese history. Many were students killed in substandard schools, creating a sensitive disaster zone inside a nation whose civil society organizations are beginning to flourish. This paper examines the education earthquake relief program of an international NGO, and the institutional environment the organization worked in. We argue that the restricted environment prevented implementation of high-impact programs in the most deprived places, but that the NGO needed to use the institutional opening created by the earthquake to establish a presence as an agent in China's development.
