Determinants of Self-Worth in Children with and without Developmental Coordination Disorder

Harter (1987) argues that both competence-importance discrepancy and social support/positive regard constructs predict a child's global self-worth. In the current study, this model was used to ascertain whether both determinants were pertinent to the self-worth of children with Developmental Coordination Disorder (DCD: American Psychiatric Association, 1994) and to control children. A group of 36 children with DCD were compared with a matched group of 36 normally coordinated children. The two groups were matched on variables of age, gender, and verbal IQ. It was found that Harter's (1987) model was supported for the group of control children as both the competence-importance discrepancy and the social support/positive regard construct were significant predictors of self-worth. However, for the DCD group, only the competence-importance discrepancy predicted self-worth. The results of this study indicate that future research efforts need to examine an alternative model which incorporates the variables that are relevant to the self-worth of children with DCD.     

Web-Based Student Assessment for Program Evaluation

As part of an overall evaluation of the Global Learning and Observations to Benefit the Environment, (GLOBE) program, we designed a Web-based assessment environment to measure students' environmental awareness and data analysis skill. It was expected that students who were identified as high implementers in the GLOBE program would outperform low implementers in their ability to construct environmental inferences and the degree to which they could analyze environmental data. Seven high and middle school classrooms were identified as either high or low GLOBE implementers depending on the amount of atmospheric data they had collected during the year. Within each classroom students were assigned into smaller learning groups of three students per group. A total of 32 groups participated in this study. Analysis of students' responses to the tasks revealed that the students differed in their performance. Overall, the results showed that students in the high implementing classrooms were more likely to construct higher-level environmental inferences than students in the low implementing classes. Contrary to expectations, middle school students were more likely than high school students to solve the data analysis problem correctly. However, upon further analyses, high school students constructed more data graphs and were more skilled in providing correct evidence to support their decision making than were middle school students in GLOBE. This study confirms the viability of using technology-based assessments for measuring students' environmental awareness and data analysis.     

Early learning about light: mapping preschool children's thinking about light before,during and after involvement in a two week teaching program

This paper reports the findings of a study which sought to first, find out four‐year‐old children's views on light and dark and second, trace the development of children's thinking about the scientific concept of light during a two‐week teaching program.
