This study examines the contribution of the knowledge produced in educational administration doctoral theses to the functions of science, concept and model development, theory formation, scale development/adaptation and application. Content analysis, one of the qualitative methods, was used in conducting the research, which analyzed 122 doctoral…

This pilot study investigates the way that young students and teachers of a Dutch Science Technology Engineering and Mathematics (STEM) secondary school subject Research and Design (R&D) reason about the concept of 'model'. The core of the Dutch Technasium secondary school course Research and Design curriculum (R&D is in Dutch called…

The main aim of this study is to teach students to take a systems perspective in understanding complex biological problems. Two lessons were designed and tested in two secondary classes (15- to 16-year-old students), using a lesson study approach. Three students from each class were observed more closely when visualizing and reasoning about two…

Out of all the complex systems in science education curricula, cellular respiration is considered to be one of the most complex and abstract processes. Students are known to have low interest and difficulties in conceptual understanding of cellular respiration which provides a challenge for teaching and learning. In this study, we took literature…

This article reports an experimental study on the effects of explicit teaching on 11th grade students' ability to reason causally in history. Underpinned by the model of domain learning, explicit teaching is conceptualized as multidimensional, focusing on strategies and second-order concepts to generate and verbalize causal explanations and…

This paper describes the result of a design study in which a geography course was developed and tested aiming to develop the Pedagogical Content Knowledge (PCK) of first-year primary student teachers. This resulted in a course called "Consciously Teaching Geography" with characteristics as (1) starting from students' preconceptions and…

When visually impaired students attend regular high school, additional materials are necessary to help them understand physics concepts. The time for teachers to develop teaching materials for such students is scarce. Visually impaired students in regular high school physics classes often use a braille version of the physics textbook. Previously,…

Disagreement exists regarding the functional locus of semantic interference of distractor words in picture naming. This effect is a cornerstone of modern psycholinguistic models of word production, which assume that it arises in lexical response-selection. However, recent evidence from studies of dual-task performance suggests a locus in…

The concept of competence is increasingly the basis for (re)designing VET. In competence-based VET academic disciplines are no longer starting points for curriculum development. Competence needed for working in practice, however, is. Competence-based learning is a dominant trend in VET in several countries because of fewer expected problems in the…

The six chapters of this theme issue consider three trends in educational effectiveness research: (1) integration of effectiveness phenomena at different levels, (2) a more model-driven approach than in the past, and (3) increased complexity of analysis tools and techniques to suit the new emphasis on process.

Uses Weinreich's (1953) partition of bilingualism to describe the effects of a small typological distance on the organization of the bilingual lexicon. Using standard Dutch and the dialect of Maastricht, subjects performed an auditory lexical decision task. (30 references) (Author/CK)
