Assessing problem solving in mathematics: Some variables related to student performance

A mathematical problem is defined here as a question not dependent on specific syllabus content, and one sufficiently new to the student such that it cannot be solved by a previously known method. With increased attention being paid to this type of mathematical problem solving at the primary school level, the need for reliable and valid methods of assessment has become more apparent. This paper reports the results of using a new problem solving test, developed for use in the upper primary school, with 371 students in Years 4,5 and 6 at government schools in Melbourne. Particular attention is given to the effects of year level, sex and the method of test administration on student performance for different types of items and different problem solving processes. The performance of Year 4 students was generally lower than that of other students, but differences were small for most items and processes between Years 5 and 6. Although most of the differences in performance between the sexes were not significant, the girls had higher scores than the boys for the total score, for all processes and for all items except the spatial item. The method of administration was important for performance, especially for the girls. The marking schedule developed enabled high intra- and inter-marker reliabilities to be obtained.     

Adult learners in the workplace: online learning and communities of practice

Seven in‐employment postgraduate Master's level students in an e‐learning unit participated in this research, designed to identify tensions between participation in a community of learning that was part of their studies, and participation in the communities of practice that they were engaged in at their workplaces. It was hypothesised that participation in both these forms of community in their different contexts may enhance each other, or could potentially have a disrupting effect on each. The research employed an interviewing technique. The students' perceptions of the impact of participation in the one form of community on their participation in the other was mixed, with some suggesting that it was enhancing, and others suggesting the contrary, or that there was no impact. The findings indicate that the enhancing effect of participation in communities of learning relevant to a learner's workplace community of practice occur when the learning tasks are designed to enable negotiation of tasks and collaboration with learners who have similar workplace issues.     

Middle-class parents’ educational work in an academically selective public high school

This article reports the findings of a study on the nature of parent–school engagement at an academically selective public high school in New South Wales, Australia. Such research is pertinent given recent policies of ‘choice’ and decentralization, making a study of local stakeholders timely. The research comprised a set of interviews with parents and teachers (n = 15), through which parents – all members of the school’s Parents’ and Citizens’ group – theorized and explained their involvement with the school, and teachers spoke about their views on this involvement. Results are organized around three themes: ‘how parents worked to nurture their children’s schooling’, ‘reasons behind parents’ involvement with the school’, and ‘communication and use of parental resources by the school’. Overall it was found that while parents were making significant efforts to involve themselves in the education of their children and with the school more broadly, the reasons for their involvement were not always consistent, but instead revealed a range of motivations for and conceptions of parents’ roles within schools, which at times were at odds with the teachers’. Through this, the study contributes to our understanding of middle-class parent engagement at an unusual and particular type of school.     

Social functioning among college students diagnosed with ADHD and the mediating role of emotion regulation

Despite the many studies that have documented the association between symptoms of ADHD and social difficulties in children and adolescents, few have examined this phenomenon in college students. In addition, the underlying factors contributing to such social difficulties are still poorly understood. We hypothesised that college students with symptoms of ADHD, namely inattention and hyperactivity/impulsivity, would continue to display social behavioural difficulties, and that emotion regulation would play a mediating role in that relationship. Ninety-nine 17–24-year-old college students filled out three questionnaires to assess Inattentive and Hyperactivity/Impulsivity Symptoms, Social Skills, and Emotion Regulation abilities. Analysis revealed that emotion regulation is a significant mediator between Inattentive Symptoms and Social Skills for female students. There was no significant correlation between ADHD symptoms and Social Skills for males. Female college students report social functioning difficulties associated with their inattentive and hyperactive symptoms, and impaired emotion regulation abilities mediate this relationship for inattentive symptoms only.     

Environmental health and toxicology resources of the United States National Library of Medicine

For over 40 years, the National Library of Medicine's (NLM) Toxicology and Environmental Health Information Program (TEHIP) has worked to organize and to provide access to an extensive array of environmental health and toxicology resources. During these years, the TEHIP program has evolved from a handful of databases developed primarily for researchers to a broad range of products and services that also serve industry, students, and the general public. TEHIP's resources include TOXNET , a collection of databases, including online handbooks, bibliographic references, information on the release of chemicals in the environment, and a chemical dictionary. TEHIP also produces several resources aimed towards the general public, such as the Household Products Database , which helps users explore chemicals often found in common household products, and Tox Town , an interactive guide to commonly encountered toxic substances, health, and the environment. This paper introduces some of NLM's environmental health and toxicology resources.     

Predictors of ability-achievement discrepancies in children referred for psychoeducational evaluation

The present study evaluated a school district's psychoeducational screening program to determine the best predictors of two difference score variables: (a) WISC-R FSIQ – PIAT reading recognition score and (b) WISC-R FSIQ – PIAT math score. The study also investigated the merit of using scores from a group-administered achievement test (CAT) as predictors. Subjects were 61 first through fifth graders initially referred for testing from 1982–1984. Multiple regression analyses indicated: (a) for reading, the SIQ score and the PPVT-R – CAT reading difference score were significant predictors, together accounting for 27% of the variance, and (b) for math, the PPVT-R score accounted for 28% of the variance, with additional variables producing nonsignificant increments. Results suggest that CAT scores may prove useful predictors when combined with screening IQ tests to form difference scores.     

Effects of a support group for siblings of children with special needs

School psychologists may provide support services to siblings of children with special needs as part of a family-focused approach to intervention. The purpose of the present study was to evaluate the effectiveness of a 6-week support group for siblings. Pre-and posttest assessments of six children who participated in the support group and five who did not indicated that the support group had a significant effect on the participants' perceptions of social support. Parental interview data also indicated some improvements in the group participants' behavior toward their siblings. No significant differences were found between the groups on measures of behavior problems, self-concept, or knowledge about and attitudes toward children with handicaps. These results provide moderate support for the effectiveness of support services for siblings of children with special needs.
