Although digital media are in general very common, their role in academic settings and their relevance for academic achievement are not satisfactorily explored. A research gap that is particularly apparent during the corona crisis in 2020 when university processes in many countries are suddenly almost completely digitalised. Research suggests a…

Assessment instruments that generate quantitative data on attributes (cognitive, affective, behavioral, "etc.") of participants are commonly used in the chemistry education community to draw conclusions in research studies or inform practice. Recently, articles and editorials have stressed the importance of providing evidence for the…

Many of the instruments developed for research use by the chemistry education community are relatively new. Because psychometric evidence dictates the validity of interpretations made from test scores, gathering and reporting validity and reliability evidence is of utmost importance. Therefore, the purpose of this study was to investigate what…

Previous systematic reviews indicate a lack of reporting of reliability and validity evidence in subsets of the medical education literature. Psychology and general education reviews of factor analysis also indicate gaps between current and best practices; yet, a comprehensive review of exploratory factor analysis in instrument development across…

Objective: To develop a youth form of the Motivators of and Barriers to Health-Smart Behaviors Inventory (MB-HSBI--Youth) for use in identifying self-reported motivators of and barriers to the following health-promoting behaviors (called "health-smart" behaviors): eating a healthy breakfast, eating healthy foods and snacks, drinking healthy…

The paper examines issues, philosophy and guidelines for psychological assessment of the disabled. Focused on are: (1) adjustments in testing procedures and (2) applicability of standard norms with commonly used psychological test instruments for the assessment of ability, interest, and personality. The importance of accurate assessment for…

Assessment has always played an important role in counseling. This book provides information about the various psychological assessment procedures that are relevant for practicing counselors. The text deals with the use of tests that are most often employed by counselors and it includes case studies. Its purpose is to help counselors become better…

This book addresses the question of what tests are measures of. Intelligence, achievement, and personality tests not based on empirical investigation have questionable validity. Some researchers now suspect that almost all tests given to students in all subjects, as well as general tests of intelligence and personality, are essentially language…

This collection of papers, concerned with the nature and theory of intelligence, forms part of a project to integrate test and factor theory with the empirical, functional relationships involving standard intelligence tests. The project will render more objective the use of factor analysis in personnel research. A definition of intelligence…

Conclusions from an examination of the results of the National Assessment of Educational Progress indicate that it furnishes little help for those involved in the publication of composition textbooks. Four main difficulties in making inferences from the Assessment data on writing are (1) it is not clear why individuals perform as well or as poorly…

Content validity involves a judgment that all knowledges, skills, abilities, and other worker characteristics (KSAOs) needed for successful job performance (or a specified portion, the job content domain), have been adequately sampled by the tests used for employee selection and promotion decision making. The model outlines the procedure for…

The general use of the Spearman-Brown formula for calculating the reliability of parallel tests with different lengths is reviewed. The importance of the assumption that the component tests be parallel is noted and the property that parallel tests must be non-negatively correlated is derived. (Author)

Outlines the procedures involved in the construction of the Canadian version of the Life Roles Inventory-Values Scale (Canadian Work Importance Study, 1986), developed in both French and English. Describes studies of the reliability (internal consistency, test-retest, and alternate form), and validity (construct, convergent, discriminant, and…

Investigated stability of the Wechsler Intelligence Scale for Children-Revised (WISC-R) intelligence quotient scores of 32 exceptional students over six-year interval. Used 20 learning disabled and 12 mentally disabled students aged 6 to 16. Test-retest findings indicated median reliability value of .74. Discusses implications for clinicians and…

Research has recognized that anxiety may exert a debilitating effect on students' academic performance; however, many studies of test anxiety have been limited by their failure to consider sex differences. Two studies were conducted to analyze sex differences of the Test Anxiety Scale (TAS) and achievement correlates and to validate a factor…
