Piaget's theory of stage structure is synonymous with discussions involving cognitive development. As with any theoretical model, researchers inevitably and rightly seek to affirm and/or contest the elements of the model presented. In this comparative study, students' performance across three hands-on engineering tasks for two distinct student…

Foundation and Year 1/2 teachers at Saint Martin de Porres Primary School, a Catholic School in Laverton, Melbourne have been collaborating with a team of researchers from Monash University on a four-year project led by Professor Peter Sullivan and colleagues. The teachers have been trialling and implementing a series of lesson sequences as part…

The middle school transition has been identified as a difficult time for youths, resulting in adjustment difficulties across a variety of domains. Although some research has examined strategies that are useful for the adjustment outcomes associated with the transition, more research understanding student perceptions of what is helpful in the…

This article is concerned with the influences that are brought to bear on the design of school buildings and the effects that the design of these buildings have on those who teach and learn in them. The article also focuses on the ways in which design is altered in and through the practices of these occupants. We argue that there is a mutual…

Three experiments investigated effects of complexity on 2- to 6-year-olds' understanding of a beam balance. Found that 2- to 4-year-olds succeeded on problems that entailed binary relations, but 5- and 6-year-olds also succeeded on problems that entailed ternary relations. Ternary relations tasks from other domains (transitivity and class…

Students (n=150) ages 11, 14, and 17 were asked to explain the meanings of 24 different idiomatic expressions. Performance on the task gradually improved as subject age increased. High-familiarity idioms were easier to explain than moderate-familiarity or low-familiarity expressions. Easier idioms tended to be more transparent. (Author/JDD)

Relational complexity (RC) theory conceptualizes an individual's processing capacity and a task's complexity along a common ordinal metric. The authors describe the development of the Latin Square Task (LST) that assesses the influence of RC on reasoning. The LST minimizes the role of knowledge and storage capacity and thus refines the…

One finding is that the children in this study did not reach a level in the development of these concepts expected by Piaget of 9-year-olds. (Authors/CB)

Eleven preschool children with Down Syndrome were taught new words/graphic symbols (Rebus or modified Bliss) using various treatment conditions. Incorporation of graphic symbols into language intervention programs may facilitate language acquisition, provided the tasks and procedures are appropriate to the child's developmental age and level of…

Discusses hierarchical complexity of tasks as a way of conceptualizing information in terms of the power required to complete a task, and its implications for developmental psychology and information science. Provides an analytic solution to the definition of developmental stages and allows for the possibility within the science of scaling the…

The purpose of this study is to see if older adults who experience problems with thought suppression tend to encounter greater difficulty deriving a sense of meaning in life. Data from a longitudinal nationwide survey of older people (N = 988) indicate that greater difficulty with thought suppression is associated with a decline in meaning over…

Discussed is a report of a British government advisory group concerning programs of study in mathematics education, as related to students with special education needs. Described are the progression of levels, the spread of levels normal for particular age groups, and the notion of age determining the work of students. (JDD)

To investigate developmental differences in timesharing performance, 60 boys, 20 in each of three age groups (7-, 10- and 13-year-olds), performed an auditory matching task and a tracking task alone and concurrently, the latter under two sets of instructions. Decrements produced by concurrent performance were compared for the three age groups.…

Documented strategies preschool children used in completing complex, multipiece puzzles, which included focus on color, design, or shape. Found that all children could benefit and enjoy working on larger puzzles in the classroom and that the activity encouraged social literacy, completing a long-term project, scaffolding, and child development.…

This study examined the hypothesis that age-related increases in reasoning ability are associated with the ability to represent relations of increasing complexity, defined as the number of entities related. The study's purpose was to determine the extent to which this ability to process relations with three entities increased between ages 4 and 8…
