This paper presents the development and validation of the 17-item mathematics Graduate Student Instructor Observation Protocol (GSIOP) at two universities. The development of this instrument attended to some unique needs of novice undergraduate mathematics instructors while building on an existing instrument that focused on classroom interactions…

Numerous studies have been published about instruments intended to quantitatively measure students' epistemic beliefs about science; however, as this researcher would discover, developing an instrument to accurately measure epistemic beliefs about physics knowledge is not always as straightforward as the literature would make it seem. Given a lack…

Experiences of wonder should be valued, protected, and promoted in academic settings. Identification of learning environments and interventions that cultivate students' capacity for wonder (CfW) first requires a means to measure it. We used a mixed-methods approach to develop and validate a measure of CfW. In the qualitative component (Studies…

Research indicates academic integration and social integration are predictors of doctoral student persistence at any program stage. However, researchers have not defined, operationalized, and measured academic or social integration consistently. Further, no instruments exist that measure academic and social integration of doctoral students in…

Secondary schools are purported to play a significant role in the resilience enhancement of adolescents; however, there are no measures of resilience designed specifically for use in secondary schools. To address this shortcoming, a resilience at secondary school (RASS) scale was developed and its psychometric properties explored. Five hundred and…

The purpose of this study is to develop a valid and reliable scale to measure the team perception levels of choir members. In the first step, a draft scale comprising 54-items was administered to 332 choir members. With the KMO (Kaiser-Meyer-Olkin) test for sampling adequacy, KMO value was found to be 0.936. Factor analysis on the scale items…

In this study, it was aimed to develop a valid and reliable scale to determine the teaching styles of teachers. The final scale composed of 44 items were applied to the 605 teachers with various branches. Participants are teachers who are working in private and public schools in the province of Hatay. This study is one of the types of quantitative…

This study aims to describe: (1) The validity and reliability of the PISA model mathematical problems on the change and relationship content developed; (2) The practicality of PISA mathematical problem models on the developed change and relationship content; (3) Students' mathematical problem-solving abilities on mathematical problems in the PISA…

We performed an exploratory factor analysis on the Online Dating Intensity Scale with a sample of emerging adult college students (N = 494). The data analyses resulted in a 1-factor, 5-item assessment that explained 60.79% of the variance.

More than three decades after their introduction, diagnostic classification models (DCM) do not seem to have been implemented in educational systems for the purposes they were devised. Most DCM research is either methodological for model development and refinement or retrofitting to existing nondiagnostic tests and, in the latter case, basically…

Designing and validating a college readiness test addresses the absence of standardized Philippine-based College Readiness Test (CRT) congruent with the College Readiness Standards (CRS) set by the Philippine Commission on Higher Education (CHED). It also resolves the varied and arbitrary indices used by Higher Education Institutions (HEIs) to…

Background: When delivered in a safe space, programs effective in promoting positive youth development (PYD) involve key features termed the Big Three: (1) Positive and sustained adult-youth relationships; (2) Life-skill-building activities; and (3) Opportunities for youth contribution and leadership. However, no measures exist in the literature…

Background: Cycling has gained more attention as an important lifelong physical activity. Learning to cycle independently without assistance is a milestone for most children that requires time and practice to master. Cycling was recently added to the motor development model and so a valid and reliable measure of cycling ability is required to…

A valid and reliable measurement tool has been developed to measure the teaching-learning process self-efficacy of instructors in higher education institutions. During the scale development stage, the scale form was e-mailed to 305 instructors, who were selected through purposive sampling method, working at the faculties of health, social,…

New Meridian Corporation has developed the "Quality Testing Standards and Criteria for Comparability Claims" (QTS). The goal of the QTS is to provide guidance to states that are interested in including content from the New Meridian item bank and intend to make comparability claims with "other assessments" that include New…
