Early Intervention,Families, and Adolescents With Down Syndrome

Developmental assessments are reported for two cohorts of Brisbane children with Down syndrome at chronological ages from 11 to 14 years. Cohort 1 was born during 1973 to 1974 while Cohort 2 was born from May 1976 to December 1978. These cohorts provided an opportunity of studying the long‐term effects of early intervention as a history‐graded influence on development; one cohort was born before early intervention became widely available whereas by the time the other children were born, a variety of programs were being offered children with disabilities. No significant cohort differences were found in MA at 11 years, 12 years and 14 years CA, in non‐verbal scores at 11 years and 12 years CA, or in adaptive behaviour scores near 13 years CA. There was no evidence of a final plateau in MA. When the cohorts were divided on the basis of early intervention commencement age, frequency and duration of attendance, there were again no group differences. SES, mothers’ education, and gender were significant predictors of MA but gender did not add significantly to non‐verbal scores. Cognitive function was strongly associated with adaptive behaviours. It was concluded that early intervention studies need to investigate social disadvantage and biological impairment not only as separate issues, but as a combination of the two. There is also a continuing need to identify the specific elements associated with SES and maternal education that influence development in children.     

Community Child Care Inclusion: the development of two children

The development of two children with severe disabilities who were fully included in a community child care centre that implemented a developmentally appropriate play‐based curriculum is chronicled in this paper. The children's development was monitored over the course of a 9‐month school year using the traditional measure of a standardised assessment instrument, as well as monthly observations of the children in various play activities. The data are presented in a case study format and provide evidence that the children in this study made progress in all areas of development. The findings are important in that they show the children with severe disabilities progressed without intensive intervention, indicating that a play‐based curriculum utilising developmentally appropriate practice may provide an effective structure for the instruction of young children with disabilities.     

Conflict Resolution Patterns of Preschool Children With and Without Developmental Delays in Heterogeneous Playgroups

The conflict resolution patterns of preschool-age mildly developmentally delayed children were compared to those of older and younger groups of typically developing children matched on the basis of chronological age or developmental level. Children participated in short-term heterogeneous playgroups consisting of representatives from all three developmental status groups. Naturally occurring conflicts with peers in the form of extended directive episodes were assessed in terms of their frequency, purpose, strategies, and the way conflicts were resolved. Results revealed that mildly delayed children exhibit a more negative and less adaptive interaction style, even in comparison to typically developing children similar in developmental level. Special problems were apparent when younger typically developing and mildly delayed children engaged in conflict episodes, whereas typically developing older children were able to adjust and interact appropriately irrespective of their companions' developmental status. In addition, typically developing older children elicited a pattern in which other children were less demanding and negative, but more responsive, positive, and adaptive. The implications of developmental differences between younger and older typically developing children and the unique problems in conflict situations were discussed.     

As Science Students Become Science Teachers: A Perspective on Learning Orientation

Spatial ability and transformational geometry

New technologies in education are placing more emphasis upon visual and spatial skills, those required to inspect, encode, transform, and construct information in visual displays. They do this by presenting students with learning material embedded in complex visual displays and hypermedia, and by requiring students to navigate through virtual space. These developments make it important for us to learn more about the underlying nature of visuospatial ability, how it is related to academic performance, and how it can be improved. This paper explores these issues in the context of instruction in transformational geometry upon geometry performance and spatial ability of Grade 7/8 students. The instructional conditions were (a) a traditional textbook approach involving paper-and-pencil tasks and verbal instruction (Traditional Group), and (b) an approach incorporating object manipulation, and visual imagery, which was designed to encourage spatial thinking (Spatial Group). Multiple regression results indicated that posttest geometry performance was predicted by pretest geometry, pretest spatial ability, and the interaction of pretest geometry and instructional condition; the interaction indicated that high prior knowledge subjects performed better in the Spatial group, low prior knowledge subjects in the Traditional group. Posttest spatial ability was predicted by handedness, pretest geometry, pretest spatial ability, and the interaction of pretest spatial ability and handedness; the interaction indicated that less right-handed subjects of low spatial ability improved on spatial ability more than their more right-handed peers.     

SELF-PERCEIVED GAINS IN CRITICAL THINKING AND COMMUNICATION SKILLS: ARE THERE DISCIPLINARY DIFFERENCES?

The influence of disciplinary differences onself-perceived gains in critical thinking andcommunication skills were examined in terms of studentbackground characteristics, experiences in the major,and college experience variables. Academicdisciplines were categorized according to Biglan's(1973a) classification of single- and multiple-paradigmdisciplines. Although multigroup structural equationmodeling showed no differences between self-perceivedgains for single- and multiple-paradigm disciplines, theproposed theoretical model accounted for 13.5% and 25.3%of the variance in self-perceived gains in critical thinking and communication skills,respectively. The variable most highly associated withself-perceived gains was the quality of lower-divisioncourses in the major.
