Creating a Developmental Scale to Account for Heterotypic Continuity in Development: A Simulation Study

Many psychological constructs show heterotypic continuity—their behavioral manifestations change with development but their meaning remains the same. However, research has paid little attention to how to account for heterotypic continuity. A promising approach to account for heterotypic continuity is creating a developmental scale using vertical scaling. A simulation was conducted to compare creating a developmental scale using vertical scaling to traditional approaches of longitudinal assessment. Traditional approaches that failed to account for heterotypic continuity resulted in less accurate growth estimates, at the person- and group level. Findings suggest that ignoring heterotypic continuity may result in faulty developmental inferences. Creating a developmental scale with vertical scaling is recommended to link different measures across time and account for heterotypic continuity.     

Differential versus equal student subsidies in post-secondary education: A current Canadian dispute

This paper examines a current proposal that students in higher education should have equal subsidies. The proposal has recently been made on grounds of efficiency and is therefore linked with the justification of subsidies because of public benefits (externalities) from education. The argument is that since we are ignorant of the differential strengths of public benefits from each educational program, it is a safe rule to subsidize each at an equal rate. This equality argument is further supported in this paper with the observation that marginal public benefits diminish with increasing educational duration. This efficiency argument is clearly distinguishable from that of equity or equality of opportunity.The strength of the argument is next tested against the objections to it that are now being made by the Ontario Commission on Post-Secondary Education. Evidence of the degree of present inequality in subsidization in Ontario is fully surveyed. It is shown that the Commission is reluctant to reduce the inequality because this will mean charging full fees for the last stages of professional training. The Commission fears that this would result eventually in the raising of professional fees to the public.This article finally produces an economic model that shows that the Commission's fears are groundless. The case for switching the subsidies in favour of the earlier years of education is indeed stronger than appears at first sight because of the monopolistic tendencies of the professions concerned.     

Occupational Outcomes for Bachelor of Science Graduates in Australia and Implications for Undergraduate Science Curricula

Recent national reports have highlighted the contribution that the sciences make to the Australian economy. Many developed economies report perceived shortages of STEM qualified workers, and at the same time, many science graduates have difficulty in finding work, especially work in their discipline. Rational education design dictates that science curricula at all levels should be based on a realistic representation of the actual practice of science graduates. So where do Australian science graduates go postgraduation? Using the Australian national census data set, we present a focussed investigation into the occupational status of Australian science bachelor graduates, how this status varies with graduate age and gender, how this status varies between science degree specialisms and how this status compares to a range of other disciplines. We consider the implications of these findings for undergraduate science degree curriculum design. We find that Australian science bachelor graduates work in a wide range of occupations, and even immediately postgraduation, only a minority of science bachelor graduates are working in traditional science occupations. Occupational outcomes vary significantly between science degree specialisms. For a contemporary undergraduate science curriculum to reflect the occupational outcomes of science bachelor graduates, there is a balance required to ensure adequate technical preparation for those students who pursue a career in their discipline as science professionals and to also address the broader knowledge, skills and attitudes that will equip the majority of graduates from Australian science programs for successful employment, further education and active participation in their communities, using their science knowledge.     

Sampling In Everyday Life in Nigeria

This article describes a means of introducing the elementary concepts of sampling with practical class based discussions to a group of first year students in a four year degree programme in Statistics and in other Science courses at the University of Ilorin, Nigeria. This class is equivalent to the Advanced level course and the students are usually of ages between 17 and 19 years.     

Applying Learning Analytics to the Scholarship of Teaching and Learning

In this article we report on the findings of a project funded by the Australian Office for Learning and Teaching and entitled “Learning Analytics: Assisting Universities with Student Retention.” While this project was primarily focused on retention as a potential outcome of learning analytics, its application could be related to the broader concept of student success. Student success allows for a focus on pedagogy and the use of learning analytics for the improvement of learning and teaching with a firm scholarly evidence base. The data gathered for the project provide the background for a discussion about the potential of learning analytics to inform the practice of the Scholarship of Teaching and Learning. A case study demonstrates the potential of this approach. Overall, clear pedagogical questions are important in the application of learning analytics to the Scholarship of Teaching and Learning, and we suggest potential ways to explore pedagogical questions with big data methods.     

On Enhancing Plausibility of the Missing at Random Assumption in Incomplete Data Analyses via Evaluation of Response-Auxiliary Variable Correlations

A procedure for evaluating candidate auxiliary variable correlations with response variables in incomplete data sets is outlined. The method provides point and interval estimates of the outcome-residual correlations with potentially useful auxiliaries, and of the bivariate correlations of outcome(s) with the latter variables. Auxiliary variables found in this way can enhance considerably the plausibility of the popular missing at random (MAR) assumption if included in ensuing maximum likelihood analyses, or can alternatively be incorporated in imputation models for subsequent multiple imputation analyses. The approach can be particularly helpful in empirical settings where violations of the MAR assumption are suspected, as is the case in many longitudinal studies, and is illustrated with data from cognitive aging research.     

Longitudinal Measurement Non-Invariance with Ordered-Categorical Indicators: How are the Parameters in Second-Order Latent Linear Growth Models Affected?

Models of change typically assume longitudinal measurement invariance. Key constructs are often measured by ordered-categorical indicators (e.g., Likert scale items). If tests based on such indicators do not support longitudinal measurement invariance, it would be useful to gauge the practical significance of the detected non-invariance. The authors focus on the commonly used second-order latent growth curve model, proposing a sensitivity analysis that compares the growth parameter estimates from a model assuming the highest achieved level of measurement invariance to those from a model assuming a higher, incorrect level of measurement invariance as a measure of practical significance. A simulation study investigated the practical significance of non-invariance in different locations (loadings, thresholds, uniquenesses) in second-order latent linear growth models. The mean linear slope was affected by non-invariance in the loadings and thresholds, the intercept variance was affected by non-invariance in the uniquenesses, and the linear slope variance and intercept–slope covariance were affected by non-invariance in all three locations.     

School diversity and social justice: policy and politics

This paper focuses on the long established diversity in the English education system – independent schools, grammar schools and religious schools – and in so doing explores tensions between education policy, politics and social justice. It explores the differential access to these different types of school, their social composition and implications for social justice and for wider society. It is argued that if social justice is to be a goal of government, further policy changes are needed over and above those that have already been made. However, the political challenges, which have limited policy changes to date, would be significant.     

An Educational Intervention Designed to Increase Women's Leadership Self-Efficacy

Women are sparsely represented in leadership in academic science, technology, engineering, mathematics, and medicine (STEMM). Cultural stereotypes about men, women, and leaders influence the attitudes, judgments, and decisions that others make about women and the choices women make for themselves. Multilevel interventions are needed to counteract the impact of these pervasive and easily activated stereotypes, which conspire in multiple ways to constrain women's entry, persistence, and advancement in academic STEMM. We describe an individual-level educational intervention. Using the transtheoretical model of behavioral change as a framework, we assessed the success of a semester course on increasing women's leadership self-efficacy for the first three cohorts of course participants (n = 30). Pre/post questionnaires showed gains in leadership self-efficacy, personal mastery, and self-esteem, and decreases in perceived constraints. Qualitative text analysis of weekly journals indicated increasing leadership self-efficacy as course participants applied course information and integrated strategies to mitigate the impact of societal stereotypes into their own leadership practices. Follow-up queries of the first two cohorts supported the enduring value of course participation. We conclude that providing strategies to recognize and mitigate the impact of gender stereotypes is effective in increasing leadership self-efficacy in women at early stages of academic STEMM careers.
