Background: Shayer, Ginsburg, and Coe (2007) showed that children leaving primary school in Y6 entered secondary school with much lower levels of understanding of the physical conservations than in 1976. It seemed desirable to investigate cognitive development in the first three years of secondary education. Aims: By using two Piagetian tests of…

The notion of general cognitive ability (or "intelligence") is explored and why the time might now be ripe for educators to re-consider the power offered by a general intellectual capacity which is itself amenable to educational influence. We review existing knowledge concerning general intelligence, including the cohabitation of general and…

Background: In the context of the British Government's policy directed on improving standards in schools, this paper presents research on the effects of a programme intended to promote the cognitive development of children in the first 2 years of primary school (Y1 & 2, aged 5-7 years). The programme is based on earlier work dealing with…

The CAME project was inaugurated in 1993 as an intervention delivered in the context of mathematics with the intention of accelerating the cognitive development of students in the first two years of secondary education. This paper reports substantial post-test and long-term National examination effects of the intervention, yet, by discussing the…

Commentary from the point of view of an applied psychologist considers the findings of five papers in this special issue on cognitive development, exploring how the contributions of each study or analysis could be used in real instruction. Some areas on which to focus applied research are discussed. (SLD)

This paper describes the application of theories underlying research-in-progress intended to enhance substantially the cognitive development of children in the first two years of Primary school. The intervention is delivered partly in the context of mathematics, and partly through an existing Y1 intervention focused on Piaget's concrete…

The relationship of cognitive development to learning science is considered. Views of thinking from both a psychological and a scientific standpoint are compared in order to shed light on current science teaching practice. Metacognition and problem solving are discussed. (Author/MT)

A sex-related difference, favoring boys, was found on initial performance of two samples (one British, one American) of 10- and 11-year-old children on tasks involving volume and density. After classroom instruction that included opportunities for interaction with appropriate materials, both sexes performed at higher levels but differences…

Assesses the physics, chemistry and biology content of the Nuffield Combined Science Course used in British schools by experimental testing to children's understanding of the course. A model by which the pupils' achievement is mapped to an estimate of their maximum Piagetian level of thinking is presented. (HM)

Addresses some criticisms of the Cognitive Acceleration through Science Education (CASE) project. Offers a different description of the CASE teaching method and presents evidence from the program. Contains 20 references. (Author/WRM)

A 1-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag on cognitive development and an age/gender interaction were also reported. (Author/KR)

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)

Describes a set of Science Reasoning Tasks which are valid and reliable for assessing the ability of children to use concrete and formal reasoning strategies and can be used by science teachers without professional training in Piagetian studies. Thirty pupils can be tested on each task in about 50 minutes. (Author/DS)

The effect of intervention lessons designed to accelerate the development of formal operations taught over a period of two years to adolescents was assessed. Results indicated that the experimental group had achieved a significantly greater gain in cognitive levels than the control group. Implications are discussed. (CW)

Describes the development of a Piagetian demonstration group test utilized to assess 9-12 year-old students' (N=161) understanding of heat and temperature. Findings include a unitary relationship between Piagetian stages of development and levels of understanding of heat concepts. (DS)
