The Effects of Faculty Demographic Characteristics and Disciplinary Context on Dimensions of Job Satisfaction

This study applies Kalleberg’s framework to better understand the effects of diverse demographic faculty characteristics on dimensions of job satisfaction. We also extend his work and the work of others to explore the contextual effects of academic disciplines on faculty job satisfaction. We find that women are consistently less satisfied than their male colleagues and that the effect of being female varies by discipline on levels of job satisfaction. We also find race/ethnicity has mixed effects on dimensions of job satisfaction but the effects of race/ethnicity tend to be constant across discipline. Our findings hold important implications for those seeking to understand the experiences of college faculty from diverse demographic backgrounds.

An analysis of burnout and job satisfaction among Turkish special school headteachers and teachers,and the factors effecting their burnout and job satisfaction

This study explores issues of burnout and job satisfaction among special school headteachers and teachers in Turkey. The purpose of the study is to determine whether there is a difference between headteachers' and teachers' burnout and job satisfaction in terms of work status, gender and work experiences, and to analyse the factors effecting their burnout and job satisfaction. In this paper, a quantitative approach has been used: 295 subjects (33 special school headteachers and 262 special school teachers) responded to the survey. As the research instruments, the Job Satisfaction Scale and Maslach Burnout Inventory were used to measure job satisfaction and burnout levels in terms of the dimensions of emotional exhaustion, depersonalization and personal accomplishment. The study results indicated that special school headteachers felt less personal accomplishment than special school teachers. However, there were no significant differences between headteachers and teachers on two burnout dimensions, namely emotional exhaustion and depersonalization, and job satisfaction. In terms of gender, males have less emotional exhaustion and personal accomplishment but higher depersonalization than their female counterparts. Females have higher job satisfaction than their male counterparts. In relation to their work experiences, more experienced subjects have higher emotional exhaustion and depersonalization than their less experienced colleagues, and also less job satisfaction than less experienced counterparts. However, more experienced subjects who participated in the study felt higher personal accomplishment than the others.     

Predicting item difficulty of science national curriculum tests: the case of key stage 2 assessments

Predicting item difficulty is highly important in education for both teachers and item writers. Despite identifying a large number of explanatory variables, predicting item difficulty remains a challenge in educational assessment with empirical attempts rarely exceeding 25% of variance explained.

This paper analyses 216 science items of key stage 2 tests which are national sampling assessments administered to 11 year olds in England. Potential predictors (topic, subtopic, concept, question type, nature of stimulus, depth of knowledge and linguistic variables) were considered in the analysis. Coding frameworks employed in similar studies were adapted and employed by two coders to independently rate items. Linguistic demands were gauged using a computational linguistic facility. The stepwise regression models predicted 23% of the variance with extended constructed questions and photos being the main predictors of item difficulty.

While a substantial part of unexplained variance could be attributed to the unpredictable interaction of variables, we argue that progress in this area requires improvement in the theories and the methods employed. Future research needs to be centred on improving coding frameworks as well as developing systematic training protocols for coders. These technical advances would pave the way to improved task design and reduced development costs of assessments.     

Weighing up the Influence of Context on Judgements of Mathematical Literacy

Mathematical literacy, viewed as a set of ideas involving applications of mathematics to real-world contexts, has recently featured in curricular discussions about the aims for mathematics education. This article explores the effect that differences in the way that a mathematical task is contextualised can have on students’ mathematical arguments and, therefore, on their perceived levels of mathematical literacy. Seventy-two students’ responses to three similar measurement tasks are described according to Kaiser and Willander’s levels of mathematical literacy. The arguments used for assigning each level of mathematical literacy are then investigated for the presence of specific macro- and micro-linguistic features. The context of the task affects what students perceive to be most relevant approaches to use, which are reflected in the arguments they give; this, in turn, affects external judgements of their level of mathematical literacy.
