Negotiating power and redefining literacy expertise: Buddy Reading in a dual‐immersion programme

This paper reports on a case study of face‐to‐face interaction around and about texts between a second grade dyad in a dual‐immersion programme. Through the lenses of Vygotskian situated cognition and Literacy Studies, classroom observations were conducted, both holistic and focused. Daily peer reading sessions between a dyad were tape recorded, and informal interviews with the teacher and the participating dyad were conducted. The analysis of participants' verbal exchanges revealed multiple pedagogical scaffolds, few of which were unexpected. As meaning making became more salient to the various collaborative literacy tasks, the roles of tutor and tutee were blurred. The shift in power also impacted the direction of language switches. Buddy Reading encouraged the peer readers to acknowledge and draw upon each other's expertise, as they redefined what it meant to be ‘a good reader’.     

Disruptive Behaviour in School,Personality Characteristics and Heart Rate (HR) Levels in 7‐ to 9‐year‐old Boys

Disruptive behaviour, as assessed by teachers, is reported as being consistently related to low base heart rates and low reactivity to mild stress. To date, most investigations have used mainstream school samples of boys within the 11‐16 age range approximately. It has been suggested that the predicted low base heart rates for antisocial children may be reversed in younger children. Present findings do not confirm such a trend in boys aged 7 to 9 years. Their responses were similar to those of older children. The implications for further research and the management of children in school are discussed.     

Accelerating the development of formal thinking in middle and high school students III: Testing the permanency of effects

Two years after the end of a two-year intervention program intended to promote formal operational thinking, the achievement of students initially 12 years of age was tested by their results in British National examinations, taken at age 16. The intervention methodology was set within the context of science learning, so the difference between experimental and control classes was examined first in terms of their science results. The boys achieved an average of 40% more grades of C or above than the controls. This grade is the minimum criterion for higher education in Britain. The achievement was not found equally in all students: About 40% of the boys and 25% of the girls showed effect sizes of two standard deviations in relation to comparable controls, whereas the others did not differ from the controls. Both boys and girls showed significantly higher achievement in English than comparable controls, with an effect size about half that for science. The boys—but not the girls—also showed higher achievement in mathematics. It is argued that this evidence supports the interpretation that the students' increased science achievement was caused by increased general intellectual capacity, and not just by improved domain-specific skills.     

AN EXPERIENTIALLY‐BASED TRAINING PROGRAMME IN CIVIL ENGINEERING

An innovative training programme providing second year students with a real taste of civil engineering practice through the construction of full‐size structures was introduced at the Nanyang Technological Institute, Singapore. Students are divided into companies, each responsible for executing the construction project for a profit, and in accordance with contract requirements in the forms of specifications and design drawings. Each company is sub‐divided into management, office and field groups. Thus the students, through a mandatory rotation of the role play, gain valuable experience in the field, office and management functions through personal involvement in such a real‐life project. To reflect the objectives of the programme, a system of assessment was developed based on the student performance at the team, group and individual levels. Due to the short history of the programme and since a true test of the effectiveness of this type of training is through the performance of the graduates, a summative evaluation is difficult to make at the present time. However, some interim feedback from the students, staff members and industrialists on students’ performance subsequent to their second year course work suggest that the programme has served well in achieving its intended objectives.     

Encouraging versatile thinking in algebra using the computer

In this article we formulate and analyse some of the obstacles to understanding the notion of a variable, and the use and meaning of algebraic notation, and report empirical evidence to support the hypothesis that an approach using the computer will be more successful in overcoming these obstacles. The computer approach is formulated within a wider framework ofversatile thinking in which global, holistic processing complements local, sequential processing. This is done through a combination of programming in BASIC, physical activities which simulate computer storage and manipulation of variables, and specific software which evaluates expressions in standard mathematical notation. The software is designed to enable the user to explore examples and non-examples of a concept, in this case equivalent and non-equivalent expressions. We call such a piece of software ageneric organizer because if offers examples and non-examples which may be seen not just in specific terms, but as typical, or generic, examples of the algebraic processes, assisting the pupil in the difficult task of abstracting the more general concept which they represent. Empirical evidence from several related studies shows that such an approach significantly improves the understanding of higher order concepts in algebra, and that any initial loss in manipulative facility through lack of practice is more than made up at a later stage.     

Biological constraints on instrumental and classical conditioning: Retrospect and prospect

The adequacy of traditional approaches to the study of animal learning to account fully for learning phenomena has been seriously questioned during the past decade. Critics of traditional analyses advocated a biological orientation to the interpretation of associative processes and introduced a variety of concepts intended to provide a new framework for the study of animal learning. This promise of a reorientation of the field has not been realized. The concepts of biological constraints, adaptive specializations, and situation specificity of learning have had a less profound influence on the general process approach to instrumental and classical conditioning than anticipated. The present paper makes explicit the conceptual bases of the original biological approaches to learning, identifies reasons why they failed to change fundamentally the study of instrumental and classical conditioning, and proposes an alternative approach to the use of ecological and evolutionary principles in studies of conditioning. We suggest a renewed comparative approach to the study of learning phenomena that avoids many of the difficulties inherent in earlier formulations by providing (1) a strategy for the discovery of adaptive specializations in learning, (2) an ecological framework for the discussion of these adaptive specializations, and (3) a renewed emphasis on the study of species differences in learning.
