Despite their many benefits, longitudinal studies are much less common than one-time data collection or pre-post intervention designs. One reason for their scarcity is that longitudinal studies introduce requirements and challenges that non-longitudinal studies do not. One of the biggest challenges is participant attrition. In order to help…

Imputation or likelihood-based approaches to handle missing data assume the data are missing completely at random (MCAR) or missing at random (MAR). However, little research has examined the missingness pattern before using these imputation/likelihood methods. Three missingness mechanisms -- MCAR, MAR, and not missing at random (NMAR) -- can be…

Respondent attrition is a common problem in national longitudinal panel surveys. To make full use of the data, weights are provided to account for attrition. Weight adjustments are based on sampling design information and data from the base year; information from subsequent waves is typically not utilized. Alternative methods to address bias from…

This strategic plan outlines the vision for IOE's research over the next five years, which can inspire and sustain the aspirations of researchers, share the vision with partners, and fulfil the responsibilities to the wider community. As well as the vision and mission, this plan also highlights IOE's research achievements, distinctive profile and…

In this case, I describe the "Paths on Life's Way (Paths)" project. The "Paths" project is the only longitudinal study of its kind in British Columbia and one of the few longitudinal studies in Canada. The research, now spanning 22 years-with a 28-year follow-up underway-is designed to provide a detailed examination of the life…

We examine the American landscape of higher education quantitative research concerning how gender and sex demographic information is collected. We use a directed content analysis to examine the prevalence and operationalization of gender and sex among widely used higher education survey instruments. Our findings illuminate a seemingly haphazard…

This paper explores the process of going back in qualitative longitudinal research (QLR) to gather later accounts of unfolding personal experiences. The design of interview-based QLR is usually premised on collecting data, over-time, around an unfolding experience or event. This design facilitates the establishment of an on-going research…

This project was a qualitative longitudinal research study into cultural and structural change in an English secondary school. The schools' consistent underperformance led to its conversion to "academy" status as part of a development under the Labour administration of 1997-2010. The Labour policy for academization was designed, first,…

This systematic review examined multiple indicators of adolescent students' engagement in school, and the indicators' associations with teacher-student relationships (TSRs). Seven psychology, education, and social sciences databases were systematically searched. From this search, 46 published studies (13 longitudinal) were included for detailed…

There has been significant interest in examining the developmental factors that predispose individuals to chronic criminal offending. This body of research has identified some social-environmental risk factors as potentially important. At the same time, the research producing these results has generally failed to employ genetically sensitive…

We investigated the experiences of research assistants in their dual role as both employees and trainees, when they were employed in a complex, mixed-methods, Canadian study on the everyday experience of living with and managing a chronic condition. A total of 13 research assistants participated in one or more components of this study: a survey (n…

To meet demands for accountability, most schools and departments of education at institutions of higher education (IHEs) gather information on their current students and graduates. This paper describes issues to consider when designing a longitudinal data collection and management system, drawing on seven years' experience developing such a…

The increasing trend of placing students with disabilities in general education classrooms has raised questions among researchers, policymakers, practitioners, and parents about classmate peer effects on all students. However, little is known about the peer effects of classmates with disabilities on the outcomes of other students in the classroom;…

This article is intended as a contribution to the debate on the epistemology of educational research. It is as much concerned with research as a social process as it is with the process of social research. The authors draw upon ways of walking, discussions of embodiment, place and materiality, and their analogues in relation to the processes of…

In this article, the author comments on James Catterall's research "Doing Well and Doing Good by Doing Art." The purpose is to understand how this study frames the argument for a high level of arts involvement in secondary school. By doing so, important characteristics and limitations of social science research and of this study in particular are…
