Developmental scientists are often interested in subgroups of people who share commonalities in aspects of development; these subgroups often cannot be captured directly but instead must be inferred from other information. Mixture models can be used in these situations. Two specific types of mixture models, latent profile transition analyses and…

This book presents different data collection and representation techniques: elementary descriptive statistics, confirmatory statistics, multivariate approaches and statistical modeling. It exposes the possibility of giving more robustness to the classical methodologies of education sciences by adding a quantitative approach. The fundamentals of…

The "Integrated Approaches to Supporting Child Development and Improving Family Economic Security" project was conducted by Mathematica Policy Research and Northwestern University for the Office of Planning, Research and Evaluation (OPRE), in the Administration for Children and Families (ACF) at the U.S. Department of Health and Human…

Embarking in an educational research paper is one of the daunting processes any scholar can go through. And the process is even harder for novice education students who wander through the plethora of terminology, styles and paradigms trying to figure out their way in that jungle called educational research. The following of the review presents the…

A concern exists that mixed methods studies do not contain advocacy stances. Preliminary evidence suggests that this is not the case, but to address this issue in more depth the authors examined 13 mixed methods studies that contained an advocacy, transformative lens. Such a lens consisted of incorporating intent to advocate for an improvement in…

In discussing the place of diverse qualitative research within psychological science, the authors highlight the potential permeability of the quantitative-qualitative boundary and identify different ways of increasing communication between researchers specializing in different methods. Explicating diversity within qualitative research is…

In this essay, the author tries to look forward into the 21st century to divine three things: (i) What skills will researchers in the future need to solve the most pressing problems? (ii) What are some of the most likely candidates to be those problems? and (iii) What are some current areas of research that seem mined out and should not distract…

This chapter presents a sophisticated approach for tracking student cohorts from entry through departure within an institution. It describes how a researcher can create a student tracking model to perform longitudinal research on student cohorts. (Contains 3 tables and 2 figures.)

A conceptual model of quality of life, developed at the Centre for Health Promotion at the University of Toronto (Canada), and associated instrumentation for collecting data from persons with developmental disabilities are presented. Results from a preliminary study with 41 participants support the reliability and validity of the model's…

The microcomputer offers social science field researchers a valuable tool for managing qualitative research data. In addition to the flexibility and efficiency of the microcomputer, the logic governing its programming and operation imposes a framework on the research process which necessitates that research decisions and strategies be explicit and…

The REDSIL model for ongoing evaluation of gifted education programs involves interviewing stakeholders, isolating and categorizing critical study issues, designing a data collection plan that uses several forms of qualitative methods, implementing the plan, analyzing data, searching literature relative to each issue, analyzing data again, and…

A framework for assessing the implementation and impact of office automation (OA) technology within shore-based facilities of the U.S. Navy is provided. Following a list of the assumptions guiding the evaluation plan, a model for data collection is presented which is based on the perspective of a work group, i.e., a small number of individuals who…

Results of data analysis on 470 journal titles illustrate complexity of the fuzzy set theory modeling process, which consists of three factors--number of missing issues, citations, circulations--and its limitations in making journal binding decisions. Procedures of research, data collection, and data analysis are discussed. Matrices are included.…

Describes use of case study method to systematically develop model of online searching behavior in which study design is flexible, data gathering and analyses are determined by subject matter, and specific procedures are decided upon while study progresses. Problems and measures taken to reduce their effect are discussed. (Eleven references are…

Instructional technologists have traditionally used the scientific or rationalistic paradigm to study the instructional potential of pictures. Naturalistic and rationalistic inquiry differ in their views of reality and truth, the relationship between the investigator and the subject, the goals of inquiry, and the role of values in inquiry.…
