In previous studies, problem solving appraisal has been identified as playing a key role in promoting positive psychological well-being. The Problem Solving Inventory is the most widely used measure of problem solving appraisal and consists of 32 items. The length of the instrument, however, may limit its applicability to large-scale surveys…

The Fundamentals in Meteorology Inventory (FMI) concept inventory exam was recently developed to gauge understanding of fundamental meteorological concepts among introductory meteorology students. The exam was iteratively tested and refined over several years using a small sample of students. With a goal of evaluating the reliability and validity…

This dissertation includes two independent research projects, one in astronomy education research and the other in planetary science/astrophysics research. In the first research effort, we investigate college students' conceptual and reasoning difficulties on the topic of planet formation pre-instruction. Through an analysis of over 1,000…

Student learning in instructional physics labs represents a growing area of research that includes investigations of students' beliefs and expectations about the nature of experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts at the University of Colorado Boulder…

Item response models (IRMs) were used to analyze Cross Racial Identity Scale (CRIS) scores. Rasch analysis scores were compared with classical test theory (CTT) scores. The partial credit model demonstrated a high goodness of fit and correlations between Rasch and CTT scores ranged from 0.91 to 0.99. CRIS scores are supported by both methods.…

Five studies document the validity of a new 8-item scale designed to measure "positivity," defined as the tendency to view life and experiences with a positive outlook. In the first study (N = 372), the psychometric properties of Positivity Scale (P Scale) were examined in accordance with classical test theory using a large number of…

This paper outlines the development of a performance assessment measure of language speaking ability, the Language Ability Assessment System (LAAS), which is highly reliable and can be examined for reliability through modern measurement theories, such as generalizability theory (G-theory) and the many-facet Rasch theory. LAAS was developed to…

Investigates the utility and predictive validity of the Learning and Study Strategies Inventory (LASSI) as a means of measuring college students' cognitive and affective growth following a study strategies course. Finds cognitive and affective growth in both regularly admitted and developmental studies students. Finds that LASSI cannot yet be used…

Fifty education majors in two sections responded to an Attitudes toward Mathematics and Its Teaching (ATMAT) scale. Results with two psychometric models, classical true-score theory and the one-parameter Rasch model, supported the ATMAT's reliability, content and construct validity, and invariance over three time points. (SLD)

This paper offers college teachers guidelines for improving their teacher made tests. It notes that teachers may focus on how well students have learned course objectives while being unaware of how the testing process itself contributes to the results obtained. The paper reports the results of a test-taking workshop designed to improve college…

This handbook was designed to help Australian technical, adult, and further education (TAFE) teachers, especially those in vocational education areas, to assess and evaluate students. The guide contains seven chapters, each written so it can stand alone. At the beginning of each chapter is an explanation of what is to follow and a statement of the…
