An apparent "crisis" of youth at-risk is a key marker in contemporary debates about young people among a range of intellectuals, social commentators and experts in various domains and centres of expertise. Drawing on aspects of the reflexive modernization, governmentality and feminist literatures, this paper explores how risk discourses emerge as…

The current study compared the effects of technological environments with that of the paper-and-pencil environment on reasoning about the concept of derivatives in the context of maximum and minimum problems. The data consisted of clinical interviews conducted with three pre-service secondary mathematics teachers and a newly registered graduate…

This study focussed on how secondary school students construct and use mathematical models as conceptual tools when solving word problems. The participants were 511 secondary-school students who were in the final year of compulsory education (15-16 years old). Four levels of the development of constructing and using mathematical models were…

The study of literature such as Orwell's works will not solve issues in contemporary culture and thought, but it can help one detect abstract language in the discussion and formulation of issues.

Based on an M.A. thesis (Snow) submitted to McGill University.

The study was designed to test the hierarchy of difficulty in the acquisition of principles of class and conditional logic for 120 children of normal intelligence, and to compare the relative rates of logic development for those children of normal intelligence with the rate of logic development found in a previous study involving 120 gifted…

To test people's ability to underestimate time requirements during planning, researchers conducted three experiments in which subjects had to estimate the time needed to do hypothetical errands in an imaginary town. The subjects comprised three separate groups of students and citizens. Variables tested included the number of errands, the total…

Analyzed are the processes of classification and seriation which form the child's ability to reason, based upon the results of eight years of experimental work with over 2000 children. The authors have found that there is a very close relation between the development of logical actions and that of sub-logical operations and actions. The fact that…

The potency of Pascual-Leone's M construct was demonstrated by experimental production of decalages on combinatorial reasoning tasks. Logical and perceptual task characteristics remained constant while the number of variables was varied so that processing demands, relative to processing capacities, were the same for subjects at each of three age…

Examined the relationship between loneliness and level of abstract thinking in 100 college students. Differential levels of abstraction in lonely versus nonlonely students were found. (Author)

A study involving dyslexic children (10-14 years old) with average and high reasoning ability and nondyslexic children with and without superior mathematical ability suggested that the high reasoning dyslexic Ss had similar abstract reasoning ability but lower computation and memory skills than mathematically gifted nondyslexic Ss.

Indicates that three provisions should be made possible for gifted students: (1) freedom to move through the course at an accelerated speed, (2) opportunity for application of abstract thinking, and (3) tutorial and audit activities for using special talents. (JOW)

Compares spatial with nonspatial reasoning ability within the same patients to determine whether spatial reasoning deficits in schizophrenics are specific to spatial types of tasks or are indicative of generalized reasoning difficulties. (Author/RK)
