BROADCAST TELEVISION AS A CAUSE OF AGGRESSION? RECENT FINDINGS FROM A NATURALISTIC STUDY

This sub‐study is part of a longitudinal naturalistic investigation monitoring the social behaviour of young children (3‐8‐year‐olds) before and after the arrival of broadcast television in St Helena, South Atlantic.

Children's free‐play behaviour in first school playgrounds was videotaped in 1994 (pre‐tv), and in 1995 and 1996 (post‐tv), and then coded and analysed by trained observers. Findings showed no significant differences in children's behaviour either across the availability of broadcast television (i.e. CNN) or with the addition of further channels (CNN plus others).     

Types and Qualities of Knowledge and their Relations to Problem Solving in Physics

Based on empirical findings and theoretical considerations related to the field of expertise research, the importance of “types” and “qualities” of knowledge in relation to problem solving in physics was investigated. The students (N =138) in this study had a level of competence that corresponds to an intensive beginner college course in physics. It was found that conceptual declarative knowledge and problem scheme knowledge are excellent predictors of problem solving performance. However, a detailed analysis shows that the first knowledge type is more typical for low achievers (novices) in physics problem solving whereas the second type is predominately used by high achievers (experts). Regarding types and qualities of knowledge and their relations to problem solving, the results of a multidimensional scaling analysis (MDS) indicate that two dimensions of knowledge can be distinguished. On the extreme limits of the first dimension, which could be named “problem solving relevance vs. structure of discipline”, are the types of knowledge and the qualities of knowledge, respectively. The second dimension of knowledge could be named “single knowledge elements vs. organised knowledge units”. There are types of knowledge as well as qualities of knowledge distributed along this dimension. Consequences of these results for improving physics education are discussed.     

Taking educational games seriously: using the RETAIN model to design endogenous fantasy into standalone educational games

We are witnessing a mad rush to pour educational content into games in an ad hoc manner in hopes that player/learners are motivated simply because the content is housed inside a game. A failure to base educational game design on well-established learning and instructional theories increases the risk of the game failing to meet its intended educational goals, and yielding students who are entertained but who have not acquired any academic skills or knowledge. Our review of standalone educational games has shown that they are not always based on sound educational principles and theories. We contend that, if academic learning is to take place, a new design paradigm must be developed. This article discusses the RETAIN design and evaluation model for educational games that was developed to aide in the evaluation of how well academic content is endogenously immersed and embedded within the game’s fantasy and story context, promoters transfer of knowledge, and encourages repetitive usage to that content becomes available for use in an automatic way.     

Whitehead's Contribution to Ecological Thought: Some Unrealized Possibilities

The organizers of this conference have given me a difficult task: that of finding heretofore unfound implications of Whitehead's philosophy for environmental thought. The task is not difficult because implications of Whitehead's philosophy for environmental thought are hard to find. They are easy to find. The problem is that so many people have found them that finding something new to say is not easy.In what follows, however, some new implications are actually ferreted out. They fall under three headings: a) the interrelations between three ways of thinking about the environment: bioregionalism, land ethics, and the philosophy of organism; b) the implications of Whitehead's philosophy of organism for environmental aesthetics; and c) the implications of Whitehead's philosophy of organism for human communities (sustainable communities) viewed as interfused with living nature.
