Purpose: This study aimed to develop an attitude scale to find out middle school students' (grades 5 through 8) attitudes towards science and to investigate the effects of grade level on students' attitudes towards science. Research Method: Cross-sectional survey method was used in this study. The attitude towards the science scale developed by…

The current study explored relations between principal self-efficacy for instructional leadership, emotional exhaustion, engagement, and motivation to quit the work as a principal. Participants in the study were 340 principals in elementary school and high school in five randomly selected counties in Norway. The theoretical frameworks for the…

This study developed and validated a measure of Locus of Control in university students. Tertiary academic locus of control is the general expectancy that university students have regarding their ability to change their academic outcomes. Students who have an internal academic locus of control expect that their own efforts, skill, or luck will…

This article presents a critical review of the Texas English Language Proficiency Assessment System (TELPAS), a large scale standardized English language proficiency (ELP) assessment developed by the Texas Education Agency (TEA) and administered since 2004. TELPAS is used as an annual summative assessment for all English Learners (ELs) in grades…

The identification of students' mental models is crucial in understanding their knowledge of scientific concepts. This research aimed to develop a Mental Models Representation Instrument on Newton's Laws (MeMoRI-NL). The ADDIE (Analyzing, Designing, Developing, Implementing and Evaluating) model was used as a research method. The sample consisted…

Background: There is an agreement that the methodological quality of randomized trials should be assessed in systematic reviews, but there is a debate on how this should be done. We conducted a construct validation study of the Physiotherapy Evidence Database (PEDro) scale, which is widely used to assess the quality of trials in physical therapy…

In this study, we examined the relationship of special education teachers' performance on the RESET Explicit Instruction observation protocol with student growth on academic measures. Special education teachers provided video recorded observations of three instructional lessons along with data from standardized, curriculum-based academic measures…

The aim of the current study is to develop a scale that measure pre-service early childhood educators' beliefs about infant and toddler education(I/TE). 384 candidate early childhood educators from different public universities were constituted the sample of the study. Reliability and validity analysis were run for the 60-items "Infant…

We have developed assessment tasks aligned to NGSS that require students to use practices along with disciplinary core ideas to make sense of energy-related phenomena. In this paper, we present an analysis of field test data and feedback from expert reviewers on the validity and reliability of a set of elementary school tasks. These tasks focused…

This study aims to reveal (1) the construct and (2) the characteristics of the developed instrument for assessing Physics cognitive learning achievement of high school students in outdoor learning models through local wisdom-based fieldwork. This research was a research and development using the approach developed by Mardapi (2012: 110). The steps…

It is often assumed that parents completing behavior rating scales during the assessment of attention-deficit/hyperactivity disorder (ADHD) can deliberately manipulate the outcomes of the assessment. To detect these actions, items designed to detect over-reporting or under-reporting of results are sometimes embedded in such rating scales. This…

We examine a commonly suggested proof construction strategy from the mathematics education literature--that students first produce a graphical argument and then work to construct a verbal-symbolic proof based on that graphical argument. The work of students who produce such graphical arguments when solving proof construction tasks was analyzed to…

How we choose to use a term depends on what we want to do with it. If "validity" is to be used to support a score interpretation, validation would require an analysis of the plausibility of that interpretation. If validity is to be used to support score uses, validation would require an analysis of the appropriateness of the proposed…

Naomi Gafni, director of Research and Development, National Institute for Testing and Evaluation, Jerusalem, Israel, has devoted a substantial part of her career to the development of admissions tests and other educational tests and to the investigation of their validity. As such she is keenly aware of the complexities involved in this process.…

The Watson-Glaser™ II Critical Thinking Appraisal (Watson-Glaser II; Watson & Glaser, 2010) is a revised version of the "Watson-Glaser Critical Thinking Appraisal®" (Watson & Glaser, 1994). The Watson-Glaser II introduces a simplified model of critical thinking, consisting of three subdimensions: recognize assumptions, evaluate…
