Values in mathematics classroom is not commonly discussed, researched, implemented, and measured although value is a significant affective aspect of mathematics learning. In this article, it is proposed that an instrument is developed to measure the said values which will benefit the teaching and learning mathematics. Discussion will focus on the…

Pseudowords (words that are not real but resemble real words in a language) have been used increasingly as a technique to reduce contamination due to construct-irrelevant variance in assessments of verbal fluid reasoning (Gf). However, despite pseudowords being researched heavily in other psychology sub-disciplines, they have received little…

The aim of this study was to examine the psychometric properties of the Social Efficacy and Outcome Expectations Scale (SEOES) on Turkish. The sample group included two groups of university students (ns = 440, 359). The validity of the scale was assessed using exploratory factor analysis, confirmatory factor analysis and concurrent validity, and…

The present study aimed at constructing a formative assessment inventory for assessing EFL instructors' conception and literacy about the issue under study. Therefore, 302 male and female Iranian EFL teachers took part in the study in a random way to fill out the researcher made questionnaire. The first draft of the scale consisted of two main…

The aim of this research is to develop an instrument that measures environmental attitudes of third grade students. The study was completed in six stages: creating scale items, content validity study, item total and remaining item correlation study, determining item discrimination, determining construct validity study and examining the internal…

The aim of this study is to investigate the applicability of ASK-R among Turkish pre-school children and determine the psychometric properties (validity and reliability) of this scale. This study was conducted with 167 students from different pre-schools in Mugla. Within the aim of the study, three different methods were set down in order to…

Introduction: The Resident Choice Assessment Scale (RCAS) is used to assess choice availability for adults with intellectual disabilities (ID). The aim of the study was to explore the factor structure, construct validity, and internal consistency of the measure in community settings to further validate this tool. Method: 108 paid carers of adults…

Previous studies have described many scales for measuring self-regulation; however, no scale has been developed specifically for self-paced open and distance learning environments. Therefore, the aim of this study is to develop a scale for determining the self-regulated learning skills of distance learners in selfpaced open and distance learning…

Valid and reliable instruments are required to appropriately study perfectionism. With this in mind, three studies are presented that describe the development and initial validation of a new instrument designed to measure multidimensional performance perfectionism for use in sport (Performance Perfectionism Scale--Sport [PPS-S]). The instrument is…

We describe the development, validation, and use of the "Learning Progression-Based Assessment of Modern Genetics" (LPA-MG) in a high school biology context. Items were constructed based on a current learning progression framework for genetics (Shea & Duncan, 2013; Todd & Kenyon, 2015). The 34-item instrument, which was tied to…

The purpose of this study was to evaluate the psychometric properties of a Perceived Benefits Scale, a Perceived Barriers Scale, and a Physical Activity Enjoyment Scale with data from a group randomized controlled trial (RCT) and a test-retest study with 1-week interval. In the group RCT at baseline and Week 17, 1,012 fifth- to eighth-grade girls…

This paper reports the development and validation of a short Use of Creative Cognition Scale in Studying (UCCS) that was inspired by the Cognitive Processes Associated with Creativity (CPAC) scale. In Study 1, items from two of the six subscales of the CPAC were excluded due to conceptual and psychometric issues to create a 21-item CPAC scale,…

Key concerns about the psychometric properties of the 25-item version of the Strengths and Difficulties Questionnaire (SDQ) have consistently been raised in the literature. The present study aimed at examining the meaningfulness of an alternative model to the SDQ in which 7 problematic items are excluded. French-speaking parents of 262 boys and…

Background: To increase physical activity among college students, new approaches are needed including the exploration of home-based exercise. However, research related to potential facilitators and barriers to exercising at home is limited. Purpose: The goal of this study was to develop a reliable and valid measure that can assess predictors of…

This study presents a validation report of the Lecturer's Teaching Assessment Scale (LTAS) developed for the assessment of lecturer's teaching effectiveness in Obafemi Awolowo University, Ile-Ife, Nigeria. It also examined the factor structure of the LTAS, its construct validity, and internal consistency reliability coefficients. The study adopted…
