The paper takes advantage of exceptionally rich longitudinal data on the universe of labor force participants in Slovenia and simulates the working of an income contingent loan scheme that seeks to recover part of schooling costs. The simulations show that under the base variant (where the target cost recovery rate is 20% and the contribution rate…

There has been an increasing interest in employing decision-theoretic framework for learner modeling and provision of pedagogical support in Intelligent Tutoring Systems (ITSs). Much of the existing learner modeling research work focuses on identifying appropriate learner properties. Little attention, however, has been given to leverage Dynamic…

This paper reports on "Web3D dance composer" for ballet e-learning. Elementary "petit allegro" ballet steps were enumerated in collaboration with ballet teachers, digitally acquired through 3D motion capture systems, and categorised into families and sub-families. Digital data was manipulated into virtual reality modelling language (VRML) and fit…

Wrap-up effects in reading have traditionally been thought to reflect increased processing associated with intra- and inter-clause integration (Just, M. A. & Carpenter, P. A. (1980). A theory of reading: From eye fixations to comprehension. "Psychological Review, 87"(4), 329-354; Rayner, K., Kambe, G., & Duffy, S. A. (2000). The effect of clause…

Two-level data sets are frequently encountered in social and behavioral science research. They arise when observations are drawn from a known hierarchical structure, such as when individuals are randomly drawn from groups that are randomly drawn from a target population. Although 2-level data analysis in the context of structural equation modeling…

This study investigated the relative engagement potential of four types of electronic screen media (ESM): animated video, video of self, video of a familiar person engaged with an immersive virtual reality (VR) game, and immersion of self in the VR game. Forty-two students with autism, varying in age and expressive communication ability, were…

Because the power properties of traditional repeated measures and hierarchical multivariate linear models have not been clearly determined in the balanced design for longitudinal studies in the literature, the authors present a power comparison study of traditional repeated measures and hierarchical multivariate linear models under 3…

Building on the Kelley and Gulliksen versions of classical test theory, this article shows that a logistic model having only a single item parameter can account for varying item discrimination, as well as difficulty, by using item-test correlations to adjust incorrect-correct (0-1) item responses prior to an initial model fit. The fit occurs…

The purpose of this study was to assess the model fit of a 2PL through comparison with the nonparametric item characteristic curve (ICC) estimation procedures. Results indicate that three nonparametric procedures implemented produced ICCs that are similar to that of the 2PL for items simulated to fit the 2PL. However for misfitting items,…

This study examines four induction models and teacher changes in science teaching practices, as a result of several mentoring programs. It explores three different computer-mediated mentoring programs, and a traditional offline induction program--in terms of interactivity, inquiry-based teaching, and topics of knowledge. Fifteen elementary science…

In the context of practicing intercultural communication skills, we investigated the role of fidelity in a game-based, virtual learning environment as well as the role of feedback delivered by an intelligent tutoring system. In 2 experiments, we compared variations on the game interface, use of the tutoring system, and the form of the feedback.…

As one of the emerging technologies, the Second Life virtual world provides learners of English as a Foreign Language with a unique opportunity of learning authentic language with native and non-native speakers of English in a virtual environment. It enables them to learn the target language in a real-life-like social communication environment. To…

Studies of informal language learning and self-instruction with online materials have recently come into prominence. However, those studies are predominantly focused on more commonly taught languages and there is a gap in the literature on less commonly taught languages (LCTL), precisely the languages that are often studied outside of formal…

Technology-informed approaches to L2 research and teaching have prompted great interest by both researchers and practitioners alike. This book highlights the relationship between digitally-mediated technologies and second language pragmatics by presenting exemplary applications of technology for both research and pedagogy. Part I presents…

The authors aimed to incorporate learning into the cognitive assessment framework that exists for static assessment data. In order to accomplish this, they derive a common likelihood function for dynamic models and introduce Parameter Driven Process for Change + Cognitive Diagnosis Model (PDPC + CDM), a dynamic model which tracks learning…
