Grounding Second Language Vocabulary Instruction in Cognitive Science

Cognitive neuroscience has gained significant insight into the mechanisms underlying the mental lexicon and their impact on second language vocabulary learning. However, relatively little effort has been put into understanding how these mechanisms may impact instructional practices. We attempt to bridge this gap. Towards that end, we first describe three main properties of the mental lexicon: words have distinct form and meaning representations; these representations are organized in multilingual network structures organized by similarity; and the representations differ in strength. Next, we translate the properties into a visual framework that we use to reflect upon how this knowledge affects three important choices in vocabulary instruction: composing word lists, selecting an instruction method, and consolidating newly acquired words. Lastly, we discuss opportunities for both science and practice, highlighting the importance of improving the ecological validity of scientific models and theories, and of developing instructional methods grounded in cognitive science.     

The integration of computer simulation and learning support: An example from the physics domain of collisions

Discovery learning is generally seen as a promising but demanding mode of learning that, in most cases, can only be successful if students are guided in the discovery process. The present article discusses a study on discovery learning with a computer simulation environment in the physics domain of collisions. In the learning environment, which is called Collision, students learned about collisions where two particles move in the same direction and interact via a conservative force in such a way that the total mechanical energy is conserved. In the experiment we conducted with Collision, we evaluated the effects of adding two different ways to guide students: model progression, in which the model is presented in separate parts; and assignments, small exercises that the student can choose to do. The effect of providing assignments and model progression was evaluated by comparing the learning behavior and learning results over three experimental conditions in which different versions of the simulation environment were presented: pure simulation, simulation plus assignments, and simulation plus model progression and assignments. Students' use of the environment was logged, their subjectively experienced workload was measured on‐line, and their learning was assessed using a number of assessment procedures. Providing assignments with the simulation improved students' performance on one aspect of a so‐called intuitive knowledge test. Providing the students with model progression did not have an effect. A subjective workload measure indicated that expanding the simulation with assignments and model progression did not raise the workload experienced by the students. © 1999 John Wiley & Sons, Inc.

Promoting prosocial pupil behaviour and the roles of counselling

Antisocial behaviour of pupils isgetting more and more attention in many countries.Information is given about relevant definitions andthe prevalence of antisocial behaviour of pupils inthe Netherlands. Policy strategies and actions toreduce antisocial behaviour at the national level,regional or municipal level, school and class level,and individual or pupil level are focussed. Researchto explain antisocial behaviour and to promoteprosocial behaviour provides clues to a moresystematic prosocial approach, which is formulated infive guidelines towards optimum education. Practiceexperiences in developing optimum education since thebeginning in kindergarten also suggest roles ofcounselling.     

The Lesson Preparation Method: a way of investigating pre-service teachers’ pedagogical content knowledge

Teacher education should build on the knowledge base that pre-service teachers already have on account of their lifelong learning in and outside of school. An international team of mathematics and science teacher educators developed a method of investigating the pedagogical content knowledge parts of this knowledge base. They asked pre-service teachers to prepare a lesson about a topic, e.g. area, as if they had to teach that lesson the next day. In this article the main aspects of the research environment are described and their effects on the research outcomes are evaluated.     

Pre-service Physics Teachers and Conceptual Difficulties on Temperature and Heat

In this article the ‘lesson preparation method’ was used to investigate pre-service teachers’ pedagogical content knowledge, in particular their knowledge of pupils’ conceptual difficulties on temperature and heat. A relation is found between the conceptual difficulties pre-service teachers expect their pupils to have and the conceptual difficulties they themselves have or have had. The discussion considers what pedagogical content knowledge teacher educators should include in the initial or inservice teacher education curriculum.     

The design and evaluation of hypertext structures for supporting design problem solving

Computer-based complex information systems are used increasingly more often, for a growing variety of purposes, in both educational and professional contexts. Since the effectiveness of information systems will largely depend on the particular purpose and the particular task context at hand, at least part of our research efforts should be directed at studying specific application areas. This paper reports a study on the use of hypertext information systems during architectural-design problem solving. Theoretical notions on design problem solving, such as distinguishing between a problem-structuring and a problem-solving phase, provide us with expectations about the changing informational needs during the design process. Specific information structures are proposed, incorporating design principles from learning research, to accommodate these informational needs. Results of an empirical study indeed showed interactions between design phase and information structure when separately inspecting the outcomes for problem structuring and problem solving. Educational implications include the use of a combination of hierarchical decomposition and cross-referencing for certain instructional goals, such as teaching complexity and abstraction.     

Notes on contributors

Social cohesion in school is reflected in social discrimination processes and the complementary social roles of teachers, pupils, other staff and pupils' relatives. School social cohesion varies in level from high, characterised by prosocial interactions, to low, characterised by antisocial or violent interactions. Antisocial behaviour is usually embedded in specific interaction patterns between different social actors and is based on specific motives or stereotypes that elicit or justify this behaviour. Comprehensive study of these patterns is enabled by information and communication technology (ICT). The aim of this study is to use ICT to investigate social interaction patterns between personal and school characteristics of secondary school teachers and their curricular and disciplinary characteristics and experience of violence, including the motives they perceive when they are the victim, perpetrator or witness of six types of violence, differentiated according to the complementary roles of pupils, other teachers, other school staff and pupils' relatives. Three questionnaires were developed and used in a nationwide Internet‐based survey in Dutch secondary schools. This school safety monitor was completed in 2006 by 5148 teachers, 80,770 pupils, 1749 educational support staff and 629 school managers. Data were checked for reliability, scale homogeneity and representativeness. Pearson correlation analysis was used to examine the social interaction patterns in teachers' data. The results reveal violence‐specific social behaviour and social‐mirroring processes between teachers and pupils in particular. Furthermore, teachers who are younger, female or working in low‐attainment educational settings apply more curricular differentiation and collaborate more with pupils on disciplinary matters than their respective counterparts. Teachers who work in low‐attainment schools, who work in cities, who are homosexual/lesbian or who do not feel most at home in The Netherlands experience more violent behaviour as a victim or witness than their respective counterparts. In particular, teachers attribute the following motives to violence: physical appearance, behaviour, level of school achievement, a handicap, being religious, gender, sexual preference and ways of dealing with non‐conforming behaviour or punishments. Compared to teachers, pupils gave a broad array of motives for every type of violence. The conclusion is that Internet‐based data‐collection procedures provide a more comprehensive and systematic picture of social discrimination and violence motive patterns in schools than has hitherto been customary.     

Strategic Innovation in HE: The Roles of Academic Middle Managers

This article explains the development of, and presents a theoretical framework for, harnessing the roles of the academic middle manager in strategic innovation in Dutch higher education, thereby increasing higher education’s ability to learn, innovate and develop a competitive advantage. The framework is developed from theoretical models of role interactions in an educational context and in business organizations. It is also based on an empirical pilot study of the role of the academic middle manager and reviews of other relevant literature. The aim of this article will be to explore and discuss ways of analyzing the way in which academic middle managers influence strategic innovations in universities.     

Finding Out How They Find It Out: An empirical analysis of inquiry learners’ need for support

Inquiry learning environments increasingly incorporate modelling facilities for students to articulate their research hypotheses and (acquired) domain knowledge. This study compared performance success and scientific reasoning of university students with high prior knowledge (n = 11), students from senior high‐school (n = 10), and junior high‐school (n = 10) with intermediate and low prior knowledge, respectively, in order to reveal domain novices’ need for support in such environments. Results indicated that the scientific reasoning of both groups of high‐school students was comparable to that of the experts. As high‐school students achieved significantly lower performance success scores, their expert‐like behaviour was rather ineffective; qualitative analyses substantiated this conclusion. Based on these findings, implications for supporting domain novices in inquiry learning environments are advanced.
