Item response theory (IRT) methodology is introduced as a tool for improving assessment instruments used with people who have disabilities. Need for this approach in rehabilitation is emphasized; differences between IRT and classical test theory are clarified. Concepts essential to understanding IRT are defined, necessary data assumptions are…

We look at three common research scenarios, one in the behavioral domain (i.e., disruptive behaviors) one in the cognitive domain (i.e., academic achievement), and one in the affective domain (i.e., anxiety and stress) for which school psychologists are asked to address important questions related to change. We list measurement and statistical…

This research consists of a longitudinal study of 12 female elementary preservice teachers' conceptual understanding over the course of several months. The context in which the participants received instruction was in an inquiry-based physics course, and the targeted science content was the cause of moon phases. Qualitative research methods,…

This article reports on a national survey designed to learn how medium and large school districts are using standards-based leadership evaluation and related human resource management practices, such as pay for performance. Surveys were sent to all school districts in the United States with student populations 10,000 and over (total n=867).…

School superintendents in 60 public school systems in Georgia were surveyed to describe strategies being pursued to prevent school violence and promote a safe learning environment. Results from the present study were compared with results from a survey of superintendents conducted by one of the authors in 1995 to determine the extent of change in…

Why do the designers of environmental education do what they do towards the environment through education? More importantly, how do they account for their design decisions (plans and actions)? Using the theoretical and methodological framework of discourse analysis, we analyse environmental education designers' discourse in terms of the discursive…

The purpose of this study is to design a constructivist learning environment that helps learning the limit concept. The study is a pretest-posttest quasi-experimental research. The control and the experimental groups were chosen from the students attending a calculus course. Worksheets were used to assess students' learning of the limit concept.…

Burnout has been identified as a significant issue among those in instructional positions.

An obstacle to broader acceptability of effect sizes in single case research is their lack of intuitive and useful interpretations. Interpreting Cohen's d as "standard deviation units difference" and R[superscript 2] as "percent of variance accounted for" do not resound with most visual analysts. In fact, the only comparative analysis widely…

Robertson (2006b) surveyed Australian vocational teachers to propose that the criteria of newness, complexity, compatibility and locus of control are influential in shaping the frequency of online functionality use. The current paper tests and further refines this proposition by comparing the likelihood that online functionalities will be used at…

This article reports on how computer software (NVIVO) was used to analyse data for a research project on design issues in e-learning. The aim of the project was to study how South African higher education has incorporated new e-learning in the delivery of programmes. The study began by exploring the emerging patterns of the use of e-learning in…

A typical card sort is an activity in which students are given a set of cards with a single concept written on each card and asked to organize the cards by grouping related concepts.

Context: Surgical services are frequently unavailable in rural American communities. Therefore, rural residents often must travel long distances to receive surgical care. Rural hospitals commonly have difficulty providing surgical services despite potential economic benefits. Purpose: The purpose of this project was to identify the key challenges…

We investigate interrelationship among income inequality, global economy and the role of the state using an unbalanced panel data set with 311 observations on 60 countries, dated from 1970 to 1994. The analysis proceeds in two stages. First, we test for effects on income inequality of variables characterizing the situation of a society in the…

Researchers examining the therapy relationship are encouraged "to study both patients' and therapists' contribution to the relationship and the ways in which these contributions combine to impact treatment outcome" (Steering Committee, 2002, p. 443). Research on the therapeutic alliance, however, is dominated by studies that examine the individual…
