Multicollinearity is a well-known general problem, but it also seriously threatens valid interpretations in structural equation models. Illustrating this problem, J. Pietsch, R. Walker, and E. Chapman (2003) found paths leading to achievement were apparently much larger for self-efficacy (.55) than self-concept (-.05), suggesting--erroneously, as…

Data that is meaningful and purposeful is collected to assess the state of our library media programs, services and policies. The way in which one can develop the skills required to collect, analyze, interpret, present, and use data is presented.

Perceptual speech assessment is central to the evaluation of speech outcomes associated with cleft palate and velopharyngeal dysfunction. However, the complexity of this process is perhaps sometimes underestimated. To draw together the many different strands in the complex process of perceptual speech assessment and analysis, and make…

Overall the past decade has not been kind to educational research. First, some "research" has been subordinated to and corrupted by ideology. Second, there has been substantial questioning of what educational research should be and a fear that the federal government is moving to a rigid orthodoxy in defining what counts as…

This paper raises some methodological concerns about the conduct, analysis and interpretation of results from the Programme for International Student Assessment (PISA) study. While in many respects PISA represents an advance on previous attempts at international comparative assessment studies, it retains certain problematic aspects. The article…

Conditional directives are used by speakers to instruct hearers which actions are to be taken should certain events occur. The authors demonstrate that conditional directives are distinct from indicative conditionals in which speakers predict what is likely to be observed should certain events occur. The 1st set of experiments shows that goal…

This case involves a dilemma that school district evaluators frequently face. A superintendent directs an evaluator to participate in a press conference and present data validating the superintendent's program to improve high school course-passing rates. The evaluator presents his analysis to the superintendent, who directs him to remove some data…

Teaching practice can improve if teachers are able to look at themselves and student data in an objective manner. In most education training programs, teachers are not taught to use data to design curriculum and analyze their instructional practices. They need training in both data management and analysis as well as in facilitating discussions…

This summary presents the main findings from a data mapping and analysis study commissioned by the Local Government Association (LGA) from the National Foundation for Educational Research (NFER) as part of a two-year development and research programme, Narrowing the Gap. This programme seeks to make a significant difference in "narrowing the…

In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were…

Background: Accountability demands are increasingly pushing school leaders to explore more data and do more sophisticated analyses. Data-driven decision making (DDDM) has become an emerging field of practice for school leadership and a central focus of education policy and practice. Purpose: This study examined principals' DDDM practices and…

Practice-as-inquiry refers to the blending of instructional practice with systematic curricular inquiry. College and university teachers, while experts in their disciplines, typically are not specialists in instructional practice. Practice-as-inquiry (also referred to as teacher-as-researcher) may function as a mechanism of continuous teaching…

This paper presents an updated cost-benefit analysis of the High/Scope Perry preschool Program, using data on individuals aged 40. Children were randomly assigned to a treatment or control group. Program costs are compared against treatment impacts on educational resources, earnings, criminal activity, and welfare receipt. Net present values are…

This paper addresses Lawson's puzzlement about the absence of prediction in William Harvey's and Marcello Malpighi's views on capillaries. In addressing the context of that enquiry, it also addresses historiographic versus philosophical models of science, contexts of discovery versus justification, normative versus descriptive interpretations of…

Relatively little research has examined the outcomes (either program completion or recidivism) of community service (CS) sentences among adult offenders in the United States, despite the fact that this form of alternative sanction has been employed in the United States for nearly 40 years. What little research exists, primarily from Europe,…
