The moderating role of additional information when learning with animations compared to static pictures

Instructional Science - In research on learning with animations compared to static pictures usually very short and narrowly defined topics are chosen. However, in school contexts such topics are...     

Semantic-aware components and services of ActiveMath

ActiveMath is a complex web‐based adaptive learning environment with a number of components and interactive learning tools. The basis for handling semantics of learning content is provided by its semantic (mathematics) content markup, which is additionally annotated with educational metadata. Several components, tools and external services can make use of that content markup, eg, a course generator, a semantic search engine and user input evaluation services. The components and services have to communicate, pass content and state changes, actions, etc including mathematical semantics and educational markup. The novel event infrastructure supports this communication. This paper focuses on the usage of the content's semantics by selected novel components and sketches the communication.

Longitudinal twin study of early reading development in three countries: Preliminary results

We have initiated parallel longitudinal studies in Australia (Byrne, PI), the United States (Olson, PI), and Norway (Samuelsson, PI) of identical and fraternal twins who are being tested in preschool for prereading skills, and in kindergarten, first grade, and second grade for the development of early reading, spelling, and related cognitive skills. Comparisons of the similarities of identical and fraternal twins will reveal the relative influence of genetic, shared family environment, and nonshared environment on individual differences at and across different stages of development. Family and twin-specific environmental information is also being directly assessed through parent questionnaires and observations by testers. Most of the data collected so far have been from preschool twins (146 in Australia, 284 in the United States, and 70 in Norway). Preliminary analyses for the preschool cognitive measures showed reliable genetic influences on phonological awareness and several measures of memory and learning. In contrast, vocabulary, grammar, and morphology showed significant shared environment and negligible genetic effects. A print knowledge composite showed both genetic and shared environment influence.     

Training International Social Change Agents: Transcending a U.S. Counseling Paradigm

Recommendations are offered for training counseling students to address international issues. The authors discuss, for instance, the importance of learning about cultures outside the United States, the role of bias in international work, the dangers of implementing mental health delivery systems based on models derived in the United States, how to broaden one's research methodology, and the role of social change. Through this article, the authors hope to inspire counseling social change agents to consider the practice of counseling beyond the borders of the United States.     

The impact of environmental factors on components of reading and dyslexia

Data from 123 male adults were analyzed to estimate environmental influences on components of literacy skills and to explore the impact of environmental factors in different approaches to define reading difficulty. Literacy skills were decomposed into general cognitive function, reading comprehension, spelling, word reading, and phonological ability. Environmental factors examined were related to home conditions, school conditions, and literacy environment. Results suggest that there is a substantial social-cultural bias in the delineation of literacy skills and in the definitions of reading disabilities. Results also suggest that phonological ability constitutes the only measure relatively unaffected by environmental influences. This study has brought forward a new argument for emphasizing phonological deficits as the core component in defining dyslexia.     

Are student exchange programs worth it?

The number of university students participating in exchange programs has risen sharply over the last decade. A survey of Swiss university graduates (classes of 1999 and 2001) shows that participation in student exchange programs depends significantly on the socio-economic background of students. We further analyze whether the participants benefit from additional advantages caused by these exchange programs. Analyses show that student exchange programs are associated with higher starting salaries and a higher likelihood of opting for postgraduate degrees. Analyses using instrumental variable estimations (IV), however, show that these outcomes are not causally related to participation in exchange programs.      

Gestalt and Functionality as Independent Dimensions of Mental Models in Science

Research in Science Education - In teaching sciences, models are often used to introduce, elaborate or simplify real-world phenomena or concepts. It is, however, often the case that misconceptions...
