Researchers strategically assess youth mental health by soliciting reports from multiple informants. Typically, these informants (e.g., parents, teachers, youth themselves) vary in the social contexts where they observe youth. Decades of research reveal that the most common data conditions produced with this approach consist of discrepancies…

This toolkit is designed to assist states as they plan for and carry out their efforts to collect, report, analyze, and use high-quality parent and family involvement data. It defines key concepts; offers guidance on ways to improve the quality of the collection, analysis, and use of parent and family involvement data; and provides resources and…

Evaluation is a key component to learning about the effectiveness of a program. This article provides descriptive statistics of the newly developed National 4-H Common Measures (science, healthy living, citizenship, and youth development) based on data from 721 California 4-H youth. The measures were evaluated for their reliability and validity of…

This book meets a demand in the science education community for a comprehensive and introductory measurement book in science education. It describes measurement instruments reported in refereed science education research journals, and introduces the Rasch modeling approach to developing measurement instruments in common science assessment domains,…

A readily implemented procedure is discussed for interval estimation of indexes of interrelationship between items from multiple-component measuring instruments as well as between items and total composite scores. The method is applicable with categorical (ordinal) observed variables, and can be widely used in the process of scale construction,…

The research into how students' attitudes affect their learning of science related subjects has been one of the core areas of interest by science educators. The development in science education records various attempts in measuring attitudes and determining the correlations between behavior, achievements, career aspirations, gender identity and…

People with a learning disability, the experts of their own experience are increasingly involved in research. We will be discussing in this paper their centrality in the development of a psychological therapy outcome measure for people with learning disabilities. Their involvement needs to go beyond giving their views to being included in the…

The assumption that an examinee's response to an item is independent of the context in which it occurs is tested. (PR)

This article provides a broad overview of the definition of web-based surveys examining some of the benefits and burdens related to using the Web for data collection. It draws upon the experience of two years of data collection on 10 university campuses demonstrating that there are noticeable differences in the speed with which web-based surveys…

Several possible models for use in attitude scaling are defined and discussed in some detail. Unfolding analysis is illustrated. (DG)

In the present study, we reject the view that computer use can be studied as an isolated variable in a learning environment. Our main objective is to develop an instrumental tool to measure different types of educational computer use in the classroom. This builds on a comprehensive review of the literature about computer use in education. This…

An historical overview of inductive logic is presented, including the logic of enumerative induction in its rule-derivative and event-predictive forms. An experimental test model of event-predictive induction in the linguistic medium is discussed along with its theoretical significance for future psychometric investigations. (Author/CM)

Highlights the theoretical differences between the approaches of R. Likert (1932) and L. Thurstone (1928) to attitude measurement. Uses real and simulated data on attitudes toward abortion to illustrate that attitude researchers should pay more attention to the empirical-response characteristics of items on a Likert attitude questionnaire. (SLD)

The validity of an evaluation model for mastery testing applications was investigated. Three variables were tested in an experiment using 96 third grade subjects--amount of training, number of alternates in an item, and number of items. The concept hierarchy involved an orderly progression from a concept involving one relevant of three varying…

In an attempt to restore the symmetry and balance between the study of person and item variation, this paper presents a novel methodology construct specification equations, which allows one to ascertain from the lawful behavior of items what an instrument is measuring. (Author/PN)
