This article illustrates (a) 2 recent innovations in the changing criterion research design, (b) how these innovations apply to research and practice in special education, and (c) how clinical needs influence design features of the changing criterion design. The first innovation, the range-bound changing criterion, is a very simple variation of…

Institutional researchers frequently use national datasets such as those provided by the National Center for Education Statistics (NCES). The authors of this chapter explore the adjustments required when analyzing NCES data collected using complex sample designs. (Contains 8 tables.)

Because surveys now can be implemented with relative ease and little cost, many researchers are overlooking the basic principles of survey research. This chapter discusses sources of error that researchers should consider when conducting a survey, and gives readers basic suggestions for reducing error. (Contains 1 table and 1 figure.)

In this paper, the authors describe their development of an introductory laboratory course in microbiology that is geared towards students in grades 8-10. The course was developed as part of the Mentoring for Science Program at Harvard Medical School, an outreach program created by the Minority Faculty Development Program, directed towards…

In this paper we discuss the complexities of interview transcription. While often seen as a behind-the-scenes task, we suggest that transcription is a powerful act of representation. Transcription is practiced in multiple ways, often using naturalism, in which every utterance is captured in as much detail as possible, and/or denaturalism, in which…

Research into the research-teaching "nexus" has undergone significant changes in focus and methodology. From an initial quantitative concern with correlating measurements of research productivity and teaching effectiveness, the empirical emphasis has shifted in favour of exploring the "experiences" of participants (academics…

This study investigates the effects of web-based assessment and practice on improving middle school students' mathematics learning attitudes. With the use of an experimental design and a combination of quantitative and qualitative methods, the study compared and contrasted the attitude achievement of students, who used the web-based assessment and…

Increasing numbers of music education researchers have begun to use qualitative methods to examine research topics using interviews, observations, documents, and archival data. In this article, I review qualitative research methodology and its origins and methods, discuss topics that have been studied by music education researchers using…

Research on the neurobiology of second language (L2) learning has historically focused on localization questions and relied on cross-sectional designs. Here, we describe an alternative paradigm involving longitudinal studies of adult, novice learners who are progressing through an introductory sequence of classroom-based L2 instruction. The goal…

Assertive community treatment (ACT) has been applied to a number of disorders in the adult population, such as schizophrenia, with some degree of success; its use in the treatment of people with intellectual disability (ID) and mental illness has received little attention. Despite the high costs of ID in health and social care, there has been very…

This study examines the impact of secondary school culture on the dual student outcomes of academic achievement and engagement with the institution attended. Elements of school culture were identified, specifically the roles played by administrators, the professional teaching staff, and the adolescent peer group. A mixed-method research design was…

Evaluation research on vocational counseling in substance dependency treatment should distinguish between the effects of counselors and counseling methods on clients' employment outcomes. Three experimental designs permit investigation of possible confounds between these types of effects: (a) nested designs (each counselor delivers one counseling…

A popular design in large-scale educational assessments as well as any other type of survey is the balanced incomplete block design. The design is based on an item pool split into a set of blocks of items that are assigned to sets of "assessment booklets." This article shows how the problem of calculating an optimal balanced incomplete block…

Over the past decade, apoptosis has emerged as an important field of study central to ongoing research in many diverse fields, from developmental biology to cancer research. Apoptosis proceeds by a highly coordinated series of events that includes enzyme activation, DNA fragmentation, and alterations in plasma membrane permeability. The detection…

The purpose of this study was to examine the effects of a motivationally designed instructional text on motivation and learning. The foundation for motivational design was provided by the combination of a model of motivation in self-regulated learning and the ARCS-approach. The model of motivation is based on concepts like expectancies,…
