The second edition of the International Test Commission Guidelines for Translating and Adapting Tests was prepared between 2005 and 2015 to improve upon the first edition, and to respond to advances in testing technology and practices. The 18 guidelines are organized into six categories to facilitate their use: pre-condition (3), test development…

Proving is a process that has important roles in terms of learning and teaching in almost all the areas of mathematics. Because the process of proof constructions an extensive process that includes skills as mathematical thinking, reasoning and making connections. Reasoning is one of the most important components of this process. However, most…

This article reviews Rosenthal and Jacobson's (1968) seminal study, "Pygmalion in the Classroom" (PC). We consider what preceded PC, the actual study, immediate criticisms of it, Rosenthal's reactions to the criticism, and, importantly, the research that followed PC from 1968 to roughly 1990. Despite critical criticisms of it, we…

Fifty years after the first international large-scale assessment (ILSA), participation in these studies continues to grow, with more than 50% of the world's countries participating. Concomitant with growth in ILSAs is an expansion in the diversity of participant countries with respect to languages, cultures, and educational perspectives and goals.…

Background: Psychological Capital (PsyCap) is a prominent, well-established model of psychosocial strengths in the organizational positive psychology literature. PsyCap is a higher order construct consisting of hope, optimism, resilience, and self-efficacy that has been identified as a powerful predictor of work-related outcomes, with strong…

Mathematical competency is related to performance in introductory statistics courses and may be a roadblock to successful course completion. We developed a new measure (Math Assessment for College Students, MACS) of basic mathematics skills that improves upon measures previously used in undergraduate settings. The MACS is freely available and…

Most questionnaires construe avoidance as resulting from a problem-solving process and analyse only a few, single-factor and mostly non-adequate, forms of avoidance. The aim of the present study was to develop a multi-dimensional questionnaire to measure avoidance among adolescents. We tested the Avoidance Questionnaire for Adolescents (AQA) with…

The aim of this study was to examine the psychometric properties of the Turkish version of Family Adaptability and Cohesion Scale IV (FACES IV) Questionnaire Package, and also to achieve a valid and reliable assessment tool for the further investigations of the Circumplex Model of Marital and Family Systems in Turkish culture. A total of 1613…

Self-Directed Learning Scale (SDLS) developed by Lounsbury, Levy, Park, Gibson, and Smith (2009) was used for determining individuals' self-directed learning. The purpose of this study was to translate the SDLS into Turkish and to investigate its reliability and validity with a sample of 272 university students. The SDLS, the Modified Schutte…

This article presents the Educators' Attitudes toward Disability Scale (EADS). This scale was developed from the Social Workers Attitudes toward Disability Scale (SWADS). A sample of 128 postsecondary educators from one college and one university in Ontario, Canada completed the EADS, the Attitudes toward Disabled Persons scale (ATDP), and a…

In this paper I discuss my experience in using the inverted classroom structure to teach a proof-based, upper level Advanced Calculus course. The structure of the inverted classroom model allows students to begin learning the new mathematics prior to the class meeting. By front-loading learning of new concepts, students can use valuable class time…

Online learning continues to grow at unprecedented rates. However, despite this unprecedented growth, there is little research on model formation and model validation for online learning. Two research-based models were created: eSUCCESS and R2D2/C3PO to help project managers, instructional designers, and developers design and implement online…

Background: Although the connection between health behaviors and Health Education is well established, elementary Health Education (EHE) readiness and delivery has been challenging to assess. Purpose: This research was intended to develop and test a valid and reliable instrument to assess school district readiness for and delivery of EHE. The…

Students struggle with proving, a fundamental activity in upper-level undergraduate mathematics courses. Learning how to prove is a difficult transition for students, as they shift from largely computation-based to argument-based work. In response, mathematics departments have instituted courses, introduction or transition to proof, designed to…

The purpose of this study was to develop a reliable and valid Likert scaled instrument to predict adult non-high school degree holders who would perform well academically in a project-based learning (PBL) assessment environment to obtain their high school diploma as opposed to traditional standardized tests such as the General Educational…
