The purpose of this study is to investigate association of data collectors' differences with the differences in reliability and validity of scores regarding affective variables (motivation toward science learning and science attitude) that are measured by Likert-type scales. Four researchers trained in data collection and seven science teachers…

Efficacy of the Measure of Understanding of Macroevolution (MUM) as a measurement tool has been a point of contention among scholars needing a valid measure for knowledge of macroevolution. We explored the structure and construct validity of the MUM using Rasch methodologies in the context of a general education biology course designed with an…

In this study, a mobile learning adoption scale (MLAS) was developed on the basis of Rogers' (2003) Diffusion of Innovations Theory. The scale that was developed consists of four sections. These sections are as follows: Stages in the innovation-decision process, Types of m-learning decision, Innovativeness level and attributes of m-learning. There…

Background: In the last few decades, researchers have turned their attention to students' understanding of scientific concepts at different school levels. The results indicate that the learners have different ideas, and most of them are inaccurate in terms of those generally accepted by the scientific community. Purpose: This study was undertaken…

Purpose: This study examined the construct validity and reliability of a therapeutic alliance measure (Children's Alliance Questionnaire [CAQ]) for children with psychosocial and/or behavioral problems, receiving therapeutic residential care or day care in the Netherlands. Methods: Confirmatory factor analysis of a one-factor model ''therapeutic…

The purpose of this pilot study was to examine the validity of a questionnaire developed to assess adult consumer understanding of nutrition marketing terms and the resulting impact on consumer behavior. Participants (n = 40) completed an electronic questionnaire. Efforts to establish validity and reliability suggest that the questionnaire is a…

Participation in shared-reading experiences is associated with children's language and literacy outcomes, yet few standardized assessments of shared-reading quality exist. The purpose of this study was to describe the psychometric characteristics of the Systematic Assessment of Book Reading (SABR), an observational tool designed to characterize…

This brief presents initial evidence about the reliability and validity of a novice teacher survey and a novice teacher supervisor survey. The novice teacher and novice teacher supervisor surveys assess how well prepared novice teachers are to meet the job requirements of teaching. The surveys are designed to provide educator preparation programs…

The reliability and validity of the Turkish-translated version of the Gifted Rating Scales (GRS) were tested on 30 preschool teachers who provided ratings for a total of 390 preschoolers aged ranging from 4 years, 0 months to 6 years, 11 months. Results indicated that the reliability and validity of all five of the GRS-P subscales were high.…

Today, it is of great importance that teachers have pedagogical and technological knowledge in addition to content knowledge. For this reason, the present study aims to develop a TPACK self-efficacy scale for preservice science teachers by following the theoretical framework of technological pedagogical and content knowledge (TPACK), as suggested…

The purpose of this study was to develop a measurement instrument for determining pre-service teachers' perceptions of competency in providing quality teaching. The initial phase of the instrument was consisted of 54 items that were composed based on theory and literature. The initial form was applied to 232 pre-service teachers. An exploratory…

Previous research has shown that interest in and concern about environmental issues tends to decrease in adolescence, but less is known about adolescents' broader consciousness of sustainable development, also including economic and social issues. This study investigates students' sustainability consciousness in the transition to adolescence. This…

Student participation in undergraduate research (ugr) may be influenced by interest in research, future career and educational plans, perceived value of undergraduate research experiences, or perceived competence in research skills. The purpose of this study was to develop a questionnaire that could be used to validly and reliably assess students'…

The Test Of Astronomy STandards (TOAST) is a comprehensive assessment instrument designed to measure students' general astronomy content knowledge. Built upon the research embedded within a generation of astronomy assessments designed to measure single concepts, the TOAST is appropriate to measure across an entire astronomy course. The TOAST's…
