Students embracing change towards more powerful learning environments in vocational education

Students’ educational engagement is both an important predictor of study success and a key preventive factor for dropout. Vocational tracks in secondary education show high dropout rates. There is strong evidence that the solution to educational disengagement lies in student‐centred, powerful learning environments (PLEs). This study investigates characteristics of PLEs from the perspective of students in vocational secondary education. Students’ perspectives on a learning environment are crucial for their satisfaction and learning engagement. Therefore, we investigated whether the perceived learning environment meets the requirements of PLEs, and to what extent it meets students’ preferences. Additionally, it was investigated whether students who perceive their learning environment as more powerful, are also more engaged for school. Survey data of 532 students showed that student perceptions of their current learning environment were largely discrepant from the characteristics of PLEs. Students strongly asked for more challenging learning pathways, in combination with adaptive learning support. Students who perceived the characteristics of PLEs as being present, reported higher satisfaction and stronger engagement than students who perceived their education to be a less powerful environment. There is a need to redesign curricula in vocational education in such a way that these more intensely implement characteristics of PLEs.

Higher Education Supported by New Technologies at the Technical University of Dresden—Problems and Initiatives

This article summarizes the technical efforts and scientific experience that have been recognized as essential for the introduction of multimedia technologies for innovative teaching and learning at the Technical University of Dresden. Beginning with conventional standards, the most important media types are discussed. Important criteria for the development of multimedia tools are investigated. Finally, the first results of a pilot project of teleteaching are reported. This article emphasizes that new didactic and psychological studies are of the same level of importance for learning success as is technological development. Therefore, the strategy envisaged does not aim at developing the virtual university in its purest form but at the enrichment of the contemporary university by innovative elements that preserve the living contact between teachers and students.     

HIGHER EDUCATION STATISTICAL INDICATORS FROM FOUR EUROPEAN UNION COUNTRIES ‐ AN OVERVIEW

Statistical indicators can be developed into an appropriate instrument for comparing national education and higher education systems. The present survey, which covers the four European Union countries of Germany, France, the United Kingdom, and the Netherlands, picks up certain of the topics included in the International Education Indicators (INES) project of OECD, and goes on to expand and to examine them in greater depth with special reference to higher education. Quantitative and other data show that the expansion of higher education is typical not only of the Federal Republic of Germany, but also of its western European neighbours. Regulations governing entry into higher education vary substantially among the four countries. Close coordination between school and higher education, rigorous selection procedures, along with intensive monitoring and supervision at the higher education institution explain not only the high success rate of British university students but also ‐ in conjunction with clearly defined curricula ‐ the relatively short period which British students spend there. The higher expenditure on supervision at British and Dutch higher education institutions is reflected in the burden on public finances. However, given the shorter period of study and the higher student success rate in the United Kingdom, one student completing higher education probably costs the British state less than one student completing higher education in Germany.

     

Pr?diktoren von Bildungsprozessen in der Konfirmandenarbeit

Non-formal education has received little attention by empirical research so far. Drawing on a representative study of confirmation work in the Protestant Church in Germany (7404 adolescents, aged 13?C14, and 1430 workers in 520 groups) a multi-level analysis predicts relevant factors for success on the level of individuals (confirmands) as well as on the group level. Criteria variables are the experience of participation, an increase in knowledge, interest in youth-groups and the experience of community. The predictors related to differences between the groups account for a high share of variance (between 11 and 22%). On the individual level, all four predictors (gender, group experience, religiosity, cultural background) are statistically significant. A context effect is identified concerning religiosity. The pedagogical aims and activities contribute to the explanation of variance to a considerable degree.     

The impact of visual communication on the intersubjective development of early parent-child interaction with 18- to 24-month-old deaf toddlers

This article presents a study that examined the impact of visual communication on the quality of the early interaction between deaf and hearing mothers and fathers and their deaf children aged between 18 and 24 months. Three communication mode groups of parent-deaf child dyads that differed by the use of signing and visual-tactile communication strategies were involved: (a) hearing parents communicating with their deaf child in an auditory/oral way, (b) hearing parents using total communication, and (c) deaf parents using sign language. Based on Loots and colleagues' intersubjective developmental theory, parent-deaf child interaction was analyzed according to the occurrence of intersubjectivity during free play with a standard set of toys. The data analyses indicated that the use of sign language in a sequential visual way of communication enabled the deaf parents to involve their 18- to 24-month-old deaf infants in symbolic intersubjectivity, whereas hearing parents who hold on to oral-only communication were excluded from involvement in symbolic intersubjectivity with their deaf infants. Hearing parents using total communication were more similar to deaf parents, but they still differed from deaf parents in exchanging and sharing symbolic and linguistic meaning with their deaf child.     

Hybrid clustering for validation and improvement of subject-classification schemes

A hybrid text/citation-based method is used to cluster journals covered by the Web of Science database in the period 2002–2006. The objective is to use this clustering to validate and, if possible, to improve existing journal-based subject-classification schemes. Cross-citation links are determined on an item-by-paper procedure for individual papers assigned to the corresponding journal. Text mining for the textual component is based on the same principle; textual characteristics of individual papers are attributed to the journals in which they have been published. In a first step, the 22-field subject-classification scheme of the Essential Science Indicators (ESI) is evaluated and visualised. In a second step, the hybrid clustering method is applied to classify the about 8300 journals meeting the selection criteria concerning continuity, size and impact. The hybrid method proves superior to its two components when applied separately. The choice of 22 clusters also allows a direct field-to-cluster comparison, and we substantiate that the science areas resulting from cluster analysis form a more coherent structure than the “intellectual” reference scheme, the ESI subject scheme. Moreover, the textual component of the hybrid method allows labelling the clusters using cognitive characteristics, while the citation component allows visualising the cross-citation graph and determining representative journals suggested by the PageRank algorithm. Finally, the analysis of journal ‘migration’ allows the improvement of existing classification schemes on the basis of the concordance between fields and clusters.
