Social Class and Educational Research

Social class has always been one of the most prominent variables in educational research, yet the various ways of classifying it have never ceased to be controversial. The author reviews the major classifications, assesses their validity, surveys the use made of them in research literature, suggests how they should be interpreted, and assesses to what degree findings couched in these terms correspond to the reality of social differences in Britain.     

Interactive Influences of Perceived Social Contexts on the Reading Achievement of Urban Middle Schoolers with Learning Disabilities

This study examined the effects of social influences in the lives of an ethnically diverse sample of fifth through eighth grade students with and without learning disabilities (LD) using survey data and academic achievement scores collected in 19 Chicago public schools from 1993–1997. Similarities and differences in student perceptions of school, family, and peer group contexts were examined. In addition, longitudinal data were analyzed using hierarchical linear modeling (HLM) to identify contextual influences on changes in student reading achievement over time. Comparisons of student responses confirm and extend existing findings in the literature concerning the perceptions of students with LD of their social environments. In particular, having a learning disability was associated with consistent, mostly negative, effects on social relations across the contexts of students’ lives, regardless of gender, race, grade, and socioeconomic status. In addition, student perceptions of their friendship groups were found to have small, but significant, effects on their growth in reading achievement over the course of middle school. While students with and without LD had somewhat different views of their social contexts, the processes working within these environments appeared to affect their reading achievement in similar ways. The results suggest that careful attention should be paid to the social contexts of students’ lives when planning academic interventions.     

Evaluating the impact of an academic teacher development program: practical realities of an evidence-based study

This study aimed to assess the impact of an entire academic teacher development programme at a Midwestern masters comprehensive university in the United States over a period of five years by examining changes in teaching and student outcomes of nine randomly selected programme participants. Researchers analysed syllabi, course evaluations, grade distributions, programme activity reports, interviews and vita, and concluded that the centre’s impact was greatest on tenure-track faculty who struggled with their teaching. Far more useful to future improvement, however, were the insights gained from reflection on study methods, the researchers’ emotional responses to their findings, their struggle to make sense of the data and grappling with the definition of ‘impact’. In this paper, the researchers share useful lessons learned and illustrate the difficulties inherent in evaluating academic development programmes, with a view to qualifying recommendations currently prevailing in the literature.     

Trust: the power that binds in team supervision of doctoral students

Team supervision of doctoral students adds new dimensions and complexities to relationships within the teams that impact functionality of the team. Trust emerged as a significant theme in recent qualitative research into the quality of team supervision of doctoral students. Trust was cited as a key component in successful team collaborations, and the missing component in dysfunctional teams. Definitions refer to trust as the belief of truthfulness, reliability or faith in another person’s abilities. My hypothesis is that trust operates as a form of power in team supervision. It is a form of power that enables voice, resilience and creativity in teams. This article concludes that placing trust in others in supervisory teams is a deliberate decision by candidates and supervisors. It is a decision to engage in a team context despite known risks and may be understood as a gamble on the reliability of others in the expectation of reciprocity. By conceptualising trust as a form of power, strategies that engender and maintain trust may be utilised more intentionally.     

Laplace Transforms Without Integration

Calculating Laplace transforms from the definition often requires tedious integrations. This paper provides an integration-free technique for calculating Laplace transforms of many familiar functions. It also shows how the technique can be applied to probability theory.
