The Sexuality Knowledge Assessment Questionnaire (SEKAQ) was designed to assess sexuality-related knowledge among adolescents and future health and education professionals, particularly within the context of school-based health education initiatives. This study developed and validated the SEKAQ, an instrument aimed at evaluating critical aspects…

The current push for principals' to be accountable for student outcomes has led to a renewed interest in the role of leadership in instructional improvement. This article describes the development and validation of a survey that focused on organisational management features that are likely to bring about improvement in instruction. The development…

Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure--WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive…

Purpose: Mean articulatory rate (MAR) is an alternative approach to measure articulation rate and is defined as the mean of 5 rate measures in minimally 10 to maximally 20 consecutive syllables in perceptually fluent speech without pauses. This study examined the validity of this approach. Method: Reading and spontaneous speech samples were…

The primary aim of this study was to cross-validate the Revised Fit, Stigma, & Value (FSV) Scale, a questionnaire for measuring barriers to counseling, using a stratified random sample of adults in the United States. Researchers also investigated the percentage of adults living in the United States that had previously attended counseling and…

Theon's ladder is an ancient method for easily approximating "n"th roots of a real number "k." Previous work in this area has focused on modifying Theon's ladder to approximate roots of quadratic polynomials. We extend this work using techniques from linear algebra. We will show that a ladder associated to the quadratic…

In this paper, we present the development and validation of a new measure of attitudinal learning--the Attitudinal Learning Inventory (ALI). While specific scales are available for measuring attitudes, they largely focus on established attitudes, not the impact of instruction on those attitudes. We developed the inventory with two explicit…

A simulation study is a useful tool in examining how validly item response theory (IRT) models can be applied in various settings. Typically, a large number of replications are required to obtain the desired precision. However, many standard software packages in IRT, such as MULTILOG and BILOG, are not well suited for a simulation study requiring…

The Survey of Earned Doctorates (SED) has historically been used to report the number of new doctorates entering over 100 different academic disciplines annually, including the field of mathematics education. In this article, we examine the validity of the use of this measure for this purpose by analyzing data from 23 institutions that grant…

We examined authors' treatment of instrument validity in a stratified random sample (n = 94) of quantitative studies published in the Journal of Agricultural Education from 2007 to 2016. A majority (78.7%) of studies reported use of either a researcher-developed instrument (41.5%) or an existing instrument modified by the researchers (37.2%). In…

Relatively little is known about differences in the quality of engineering education within and across countries because of the lack of valid instruments that allow for the assessment and comparison of engineering students' skill gains. The purpose of our study is to develop and validate instruments that can be used to compare student skill gains…

Objective Structured Teaching Exercises (OSTEs) are used to evaluate feedback skills. OSTEs are simulated teaching scenarios using standardized learners and trained facilitators to deliver immediate feedback to participants. As per researchers' limited knowledge, there is no published assessment tool to assess the feedback skills using OSTE in…

Purpose: The purpose of this study is to examine the psychometric properties of the Career Adapt-Abilities Scale (CAAS-Arabic form) and investigates the relationship between Emirati students' employability skills and their career adaptability in the workplace, against the backdrop of the Fourth Industrial Revolution (IR 4.0).…

Measuring cognitive load is important in virtual learning environments (VLE). Thus, valid and reliable measures of cognitive load are important to support instructional design in VLE. Through three studies, we investigated the validity and reliability of Leppink's Cognitive Load Scale (CLS) and developed the extraneous cognitive load (EL)…

This manuscript focuses on how students make sense of proofs. Participants were students who engaged in peer-review conferences of each other's attempted proofs in a graduate-level real analysis course for mathematics teachers. Building on the concept of distance from conversational analysis, we distinguish how three types of distance (epistemic,…
