Racially and ethnically diverse populations from minoritized backgrounds are often exposed to research methodologies that amplify structural racism and negate their sociocultural reality. Although cross-cultural validation of measures is considered a requisite step to multigroup comparisons, researchers apply measures validated and standardized in…

The rapid expansion of Artificial Intelligence (AI) in our society makes it urgent and necessary to develop young students' AI literacy so that they can become informed citizens and critical consumers of AI technology. Over the past decade many efforts have focused on developing curricular materials that make AI concepts accessible and engaging to…

The aim of this study is to develop a theoretically sound, valid, and reliable scale to examine seventh and eighth grade students' attitudes towards so-called skill-based mathematics questions (SBMQ). The sample of the study was 820 seventh and eighth grade students at three different middle schools in Etimesgut District of Ankara Province. A…

Although the impact of non-cognitive factors, such as math anxiety, math test-taking anxiety, and attitudes toward mathematics, has been extensively studied, this area remains partially unexplored in the realm of national assessments. This research focuses on the analysis of the validity and reliability of an 11-item questionnaire introduced by…

This study fills a gap with TPACK instrumentation by validating a survey instrument for use specifically with secondary mathematics in-service teachers in the United States using an instrument originally developed in Australia (Handal et al., 2012). A comparable national sample was surveyed in the U.S. to the original Australian instrumentation…

We present a case study of proving by three 12-13-year-old students with different levels of mathematical giftedness. After analysing students' proofs, we conclude that: there was a relation on the consistency and the students' levels of mathematically giftedness, being the least consistent the student not mathematically gifted and the most…

The aim of this study is to construct a STEM competencies assessment framework and provide validity evidence by empirically testing its structure. Common interdisciplinary assessment frameworks for STEM seem to be scarce in the literature. Many studies use students' mathematics or science scores obtained from large-scale assessments or exams to…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…

Purpose: There is little consensus in the literature regarding a) what it means for a school leader to lead with data, and b) how to measure data-informed leadership in a reliable and valid way. This study examines the psychometric properties of an operational measure intended to assess the extent to which a school leader is a data-informed school…

The purpose of this study was to adapt the Expectancy Value Scale, Students' Motivation for Homework Scale, Homework Interest Scale, Homework Affective Attitude Scale, Math Homework Purposes Scale into Turkish and to develop the Homework Self Efficacy Scale. 1555 middle school students of 5th and 8th grades participated in the study. The students…

In this paper, Harel and Sowder's proof schemes of taxonomy were applied for identifying eighth grade students' learning of proof and proofing. This study aimed to examine what kind of proof schemes are used in geometry and measurement learning areas and student's skills in giving proof and their opinions about proof. Qualitative methods were…

Middle level school teachers commonly measure and monitor students' academic performance, but such is not the case for students' classroom behavior. This is unfortunate, given the rise in students' classroom behavior problems in middle school, especially for students who experience emotional or behavioral disorders. The Classroom Performance…

Phonemic awareness refers to the ability to reflect on and process the sounds of spoken language and to conduct mental operations on the units that represent them, that is, phonemes. This study intended to examine the descriptive and psychometric properties of the phonemic awareness of schoolers test assessment (PASTA), a new tool that assesses…

Many schools and communities conduct regular surveillance surveys to monitor student mental health risk. These surveys rarely ask about use of mental health services, despite the potential importance of this information to support service planning and resource allocation. The current study developed and tested the Adolescent Mental Health Support…

Inquiry learning is a powerful strategy to instill scientific thinking into the student. Therefore, it was aimed to develop a scale of inquiry learning skills towards geometry in this study. The study was designed according to a scanning model. The study group was determined according to the convenience sampling method. 514 middle school students…
