This volume contains 11 appendices to a user's manual that provides guidance and documentation for users of the public release data for the student component of the National Education Longitudinal Study of 1988 (NELS:88). The general aim of the NELS, a continuing long-term project, is to study the educational, vocational, and personal development…

Although color vision deficiency is a prevalent problem in childhood, little is known about the cognitive and social-emotional variables linked to this difficulty. A review of the literature revealed seven empirical articles exploring the psychological functioning of color-deficient children, with the results yielding contradictory findings. The…

This paper reviews five broad types of research that are designed to determine whether or how teacher education has made a difference to teachers. The five genres consist of: (1) a line of reasoning about where one might look for the effects of teacher education and how one might design a research study to see the impact of teacher education; (2)…

The practice of student teaching is used in this report to describe a structural design model for educational practices and to illustrate applications of the model. Developing such a model involves analyzing research studies and describing related practices. The results of the research analysis in this study are applied to student teaching in the…

Missing data for a given cohort of students in a longitudinal study occurs for at least two reasons: either the student has moved or otherwise become unavailable for testing, or the cohort was not in the testing range at a given testing time. A developmental sampling for time of testing x cohort x grade research plan of testing is used to…

The Education Voucher Demonstration began in the Alum Rock Union Elementary School District during the 1972-73 school year. Under the voucher concept, parents freely select a school for their child and receive a credit or voucher equal to the cost of the child's education that is paid directly to the school upon enrollment. It was presumed that…

This paper questions both what was being tested in prior instructional media research on the educational value of film and television and the value of some of those findings. An alternative way of conceptualizing the communication process that occurs when students view an instructional film or television program is proposed, which places viewers…

The process by which the student formulates conceptions of the university and the impact of this process on the decision to persist at the university were studied with first-time Mexican American college freshmen. A multiple-subject research design--a modified analytic induction technique--was employed in order to develop a descriptive model.…

This study examines the application of the marginal maximum likelihood (MML) EM algorithm to the parameter estimation problem of the three-parameter normal ogive and logistic polychotomous item response models. A three-parameter normal ogive model, the Graded Response model, has been developed on the basis of Samejima's two-parameter graded…

Laboratory simulations combine the strengths of lab experiments and field studies while avoiding many of their liabilities. They permit the emotional involvement, the time needed for development of norms and interlocked systems of interaction, and the broad range of variables typical of field settings, yet allow for experimental controls and…

The purpose of this article is to suggest that the research on curriculum and instruction flowing out of the university will be vastly improved through collaboration with secondary school faculty, to recommend an increase of funds for collaborative research with universities on curriculum and instruction, and to suggest research designs that are…

A classroom/laboratory exercise has been used to introduce college students to factorial research designs, differentiate between interpretations for experimental and quasi-experimental variables, and exemplify application of laboratory research methods to test practical questions (advertising claims). The exercise involves having randomly divided…

This paper explores some ways research can be used to create a more integrated theoretical understanding of the interaction between individual cognition and social/cultural context as the motive force in literate acts. Drawing on data from recent research on writing, the paper proposes three principles that inform a more complicated interaction…

In March 1989, the Northwest Regional Educational Laboratory entered into a contract with the Nevada Department of Education to develop this evaluation design for the Nevada Proficiency Examination (NPE) Program. The NPE program, mandated by state legislation, requires each school district to administer examinations in all public schools to…

This booklet was written to help teachers plan their own research. It concentrates on how to translate an issue of general concern to a teacher or group of teachers into a worthwhile and feasible piece of research. The booklet is divided into four sections: section 1 deals with the purpose of doing research. It stresses that research questions can…
