To examine the reliability and validity of 1-mile walk tests for estimation of aerobic fitness (VO[subscript 2max]) in 10- to 13-year-old children and to cross-validate previously published equations. Participants (n = 61) walked 1-mile on two different days. Self-reported physical activity, demographic variables, and aerobic fitness were used in…

One out of every three students who begin an academic school year does not return for a second year, which has remained unchanged for the past 50 years. The Seven Principles for Good Practice in Undergraduate Education could improve the classroom learning environment, which could lead to increased student satisfaction and retention. More empirical…

Research validating mindfulness-based interventions with youths and in schools is growing, yet research validating measures of youths' mindfulness in schools has received far less empirical attention. The present study makes the case for and reports on the preliminary development and validation of a new, 15-item, multidimensional, self-report…

This quantitative pilot-study empirically tested the factor structure and reliability of the newly developed Graphical Inventory of Ethical Leadership (GIEL) scale, a Likert-style scale for quantifying key concepts related to ethical leadership. Correlations and principal components analyses were performed using pre-existing data as self-reports…

Science standards of different countries introduced disciplinary core ideas and crosscutting concepts--such as energy--to help students develop a more interconnected science understanding. As previous research has mostly addressed energy learning in specific disciplinary contexts, this study targets students' cross-disciplinary understanding of…

This article describes the development and preliminary validation of the Attitudes Toward Anger Management Scale (ATAMS), a self-report measure of attitudes toward anger management services. Undergraduate volunteers ("N" = 415) completed an initial version of the instrument. Principal components analysis yielded a two-factor solution.…

The current article presents the findings on the development of a student evaluation instrument in which course evaluation is directly tied to student learning outcomes. With a committee consisting of instructors from six distinct disciplines brought together as part of a working group for this purpose, the instrument was developed utilizing…

This article describes the development and validation of the Career Competencies Indicator (CCI); a 43-item measure to assess career competencies (CCs). Following an extensive literature review, a comprehensive item generation process involving consultation with subject matter experts, a pilot study and a factor analytic study on a large sample…

"Item difficulty modelling" is a technique used for a number of purposes such as to support future item development, to explore validity in relation to the constructs that influence difficulty and to predict the difficulty of items. This research attempted to explore the factors influencing question difficulty in a general qualification…

The purpose of this study was to develop and evaluate a History Interest Inventory (HII) to measure Chinese K-12 students' history interest. In this study, data were drawn from two independent samples of a city in Eastern China, and exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted to reduce instrument size…

Used multiple regression analysis to derive a short form for the Wechsler Intelligence Scale for Children-Revised in a sample of 300 children receiving treatment and/or evaluation at a university-affiliated community mental health center. Results yielded several four- and five-subtest predictive equations with demonstrable predictive validity.…

This dissertation study examined the reliability and validity claims of a modified version of the Spanish Modern Language Association Foreign Language Proficiency Test for Teachers and Advanced Students administered at George Mason University (GMU). The study used the 1999 computerized GMU version that was administered to 277 test-takers via…

A method for developing statistically parallel tests based on the analysis of unique item variance was developed. A test population of 907 basic airmen trainees were required to estimate the angle at which an object in a photograph was viewed, selecting from eight possibilities. A FORTRAN program known as VARSEL was used to rank all the test items…

Bloom's taxonomy of the cognitive domain consists of six major levels: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. The purpose of this study is to construct a quantitative causal model for a set of tests designed to operationally define these six levels in order to further explore the validity of the cumulative…

The purpose of the present investigation was to develop a construct validity approach for testing whether the separation of positive and negative item subscales is substantively meaningful in self-concept research. Results from three published studies using the Self Description Questionnaire (SDQ) III were reanalyzed. The SDQ III measures 13…
