A Comparison of Alternative Matching Strategies for DIF Detection in Tests That Are Multidimensional

Most currently accepted approaches for identifying differentially functioning test items compare performance across groups after first matching examinees on the ability of interest. The typical basis for this matching is the total test score. Previous research indicates that when the test is not approximately unidimensional, matching using the total test score may result in an inflated Type I error rate. This study compares the results of differential item functioning (DIF) analysis with matching based on the total test score, matching based on subtest scores, or multivariate matching using multiple subtest scores. Analysis of both actual and simulated data indicate that for the dimensionally complex test examined in this study, using the total test score as the matching criterion is inappropriate. The results suggest that matching on multiple subtest scores simultaneously may be superior to using either the total test score or individual relevant subtest scores.     

The Effect of Pupil Cognitive Style and Position of Prose Passage Title on Recall

A replication of Bransford and Johnson's (1972) experiment on contextual prerequisites was carried out with the additional inclusion of cognitive styles as independent variables. A total of 77 10‐ and 11‐year‐old subjects (year 6, primary school) were asked to read a short prose passage on the topic of washing clothes. Half of the subjects were told the title of the passage before reading it and half after. All subjects attempted to free recall the passage. They had also completed the Cognitive Styles Analysis (CSA) (Riding, 1991), thus providing their position on the two fundamental cognitive style dimensions: Wholist‐Analytic and Verbal‐Imagery. It was found that the Wholist‐Analytic cognitive style and title‐passage order interacted in their effect on recall (p < 0.05). Whilst Wholists performed best when the title was presented before reading the passage, the order made no difference for other individuals. This suggested that this cognitive style reflects the way individuals organise information.     

Developmental Change in Infants' Responses to Stress

Infant stress responses to a well-baby physical examination and inoculation were observed longitudinally at 2, 4, and 6 months of age. In general, there were cortisol increases over base to the procedures. Cortisol level and cortisol response decreased with age. These data indicate a developmental shift in adrenocortical functioning between 2 and 6 months of age. Further evidence for this shift was seen in the stability of individual responses between 4 and 6 months of age. Individual differences in both cortisol and behavioral responses showed the most stability between these 2 ages. Moreover, diurnal variation in baseline cortisol level was present only at 6 months of age. While a sizable minority of infants showed stress-related cortisol decreases to the procedures at a given age, there was no evidence for cross-age consistency in individual infants showing these cortisol decreases.     

An interdisciplinary approach to environmental and sustainability education: developing geography students’ understandings of sustainable development using poetry

Education for sustainable development (ESD) persists as an important concept within international policy and yet, despite considerable debate, there remains a lack of consensus as to a pedagogy for ESD in schools. This paper presents findings from a study investigating how an interdisciplinary approach to ESD in England developed one class of 16- and 17-year-old geography students’ understandings of sustainability. The research used students’ drawings of sustainable cities alongside questionnaires and semi-structured interviews to explore their understanding of sustainable development within a constructivist, case study framework. The study found that the use of poetry within a geography lesson developed students’ appreciation of the social and economic dimensions of sustainability, although their focus persisted around the environmental. As such, it is argued that an interdisciplinary approach to ESD encourages students to engage more critically and affectively with the concept of sustainable development, thereby developing a more holistic appreciation of it.     

Designing a program to prepare graduate students for careers as college teachers

Graduate students have few opportunities to gain experience in the full range of teaching and to become aware of the issues related to a career of teaching in higher education. A program designed to provide these opportunities must accommodate both the variation within the institution's graduate programs and the complexities of graduate student life to be successful. The University of California, Davis, developed the Program in College Teaching in which participants develop and then fulfill contractual agreements for a faculty guided investigation into teaching in the discipline and supporting individualized activities focused on the practice and issues of teaching in higher education. This article notes five factors and assumptions of program development, discusses how they impact a program for training graduate students to be college teachers, describes the current Program and evaluates its pilot year.William E.

A review of interventions for adolescents with insomnia and the role of the educational and child psychologist: when sleep does not come easily

The role of an educational and child psychologist involves the promotion of mental health and wellbeing. While adolescents who have insomnia are usually referred to Primary Healthcare services, it might be argued that insomnia can be seen as a barometer of psychological wellbeing and should warrant a psychological intervention. A search of PSYCHINFO and Medline revealed that interventions carried out thus far with adolescents who have difficulty initiating and/or maintaining quality sleep include Sleep Hygiene and Sleep Education, Cognitive Behavioural and Multi Component interventions. In this review it will be posited that using multi-modal approaches which are tailored to specific needs may have the most positive outcomes in the treatment of insomnia, by helping adolescents to develop a sense of self-efficacy and emotional regulation in the context of family and peer support. Educational and child psychologists are ideally placed to offer this type of input to adolescents with insomnia.
