The questionnaire is based on a vignette with one learning and one performance situation in a classroom, and is intended for students in grades 4 to 7. On a sample of N = 639…

Awareness of informational text structures is related to reading comprehension and varies according to characteristics of readers and texts. The purpose of this study was to develop and refine a measure of text structure awareness, the Text Structure Identification Test (TSIT), by investigating its internal consistency reliability and construct…

The purpose of this research was to develop a curriculum design evaluation instrument in strengthening Al-Irsyad ideology. The research activity began with a literature review on the curriculum then continues with the development of the instrument. The results of the development of the instrument items were validated by 11 experts and tested on a…

Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

The purpose of this study was to develop and validate a survey of opportunities to participate (OtP) in science that will allow educators and researchers to closely approximate the types of learning opportunities students have in science classrooms. Additionally, we examined whether and how opportunity gaps in science learning may exist across…

The aims of the study were (1) to develop a domain-general computer-based assessment tool for inductive reasoning and to empirically test the theoretical models of Klauer and Christou and Papageorgiou; and (2) to develop an online game to foster inductive reasoning through mathematical content and to investigate its effectiveness. The sample was…

Critical consciousness represents the analysis and critique of structural inequalities, the motivation and perceived capacity to effect change, and social action to redress inequity. A wave of recent instruments measuring critical consciousness have been rigorously validated. Yet, whether these measures efficiently assess different levels of…

The sample consisted of 176 superior students from grades five and six in Qatar. The results revealed a high…

The school climate measure (SCM) has demonstrated robust psychometrics in regionally diverse samples of high school-aged adolescents, but remains untested among early adolescents. Confirmatory factor analysis was used to establish construct validity and measurement indices of the SCM using a sample of early adolescents from public schools located…

This study aims to design mathematical literacy instruments that have evidence of content and construct validity and are reliable for use as an assessment for learning. The research involved eight experts as instrument validators and 273 eighth-grade students of junior high school in Yogyakarta Province. The results showed that the ten…

This article describes the development and validation of an Innovation Attitude Survey (IAS) composed of 16 Likert-type items selected to measure middle school students' attitudes toward innovation and leadership in the advancement of new ideas. The goal of developing the IAS was to identify desirable dispositions that may be related to future…

Psychological sense of community among early adolescents has been investigated using instruments developed for adolescents/adults or ad hoc scales. The aim was to contribute to the validation of a scale of Sense of Community in Early Adolescents (SoC-EA) using a 3-year longitudinal study. Participants were 576 Italian students attending middle…
