The aim of this study was to develop a valid and reliable measurement instrument to find out adolescents' relative deprivation levels and to determine the statistical characteristics of the instrument. The Relative Deprivation Scale-Adolescent Form was prepared and applied to 586 adolescents within the scope of the study. Exploratory Factor…

Internalizing and externalizing problems are common targets for school mental health screening. Prior research supports the interpretation of scores from the Youth Internalizing Problems Screener (YIPS) and the Youth Externalizing Problems Screener (YEPS), which were developed separately yet intended as companion measures. We extended previous…

This study focused on developing physics test instruments for senior high school students on the topics of temperature and heat. The study aimed to determine (i) the quality of the test instrument content, (ii) the feasibility of the test instrument, and (iii) students' graphic representation abilities on "Temperature and Heat" topics.…

Identifying a student's mental model is important for understanding scientific concepts. Dispersion and polarization are the sub concept of physics that studied in high school on light waves concept. This study aimed to develop dispersion and polarization conceptual inventory (DIPOLCI) to identify students' model mental using Rasch analysis. The…

Objective: The present study was conducted to test the validity and reliability of the Academic Life Satisfaction Scale (ALSS) on adolescents. Design: Two different samples were recruited for data collection. The first sample consisted of a total of 423 high school students, 272 (64.3%) females and 151 (35.7%) males, with a mean age of 15.97 (SD =…

The aim of this study is to compare the results of correlation coefficient estimation of reliability with those obtained through the Bland-Altman plot technique. The scale was first divided into two halves using three different approaches. A linear and high-level relationship was found between the scale scores obtained from the halved forms.…

The study's objectives are to i) develop a test kit to determine the ability of multiple intelligences (MI) to play basketball in high school and ii) measure a student's MI test ability in playing basketball. The method used is the development of instruments with analysis, design, development, implementation, and evaluation (ADDIE). The study…

The social appreciation of cultural heritage is a process where knowledge, values and relationships that people develop around their heritage assets converge.

Purpose: The purpose of this study is to explore the role skepticism plays among adolescents' online information literacy skills. Design/methodology/approach: The authors provide the conceptual grounding to operationalize and measure the notion of skepticism in an online information literacy context. Inspired by an existing measure known as the…

Chemical thinking is widely acknowledged as a core competency that students should develop in the context of school chemistry. This study aims to develop a measurement instrument to assess students' chemical thinking. We employed the Essential Questions-Perspectives (EQ-P) framework and Structure of Observed Learning Outcome (SOLO) classification…

The rise and growing prevalence of juvenile delinquency is a matter of concern for many parties. This study aims to establish a research instrument in the form of a questionnaire that can be deployed to assess the learning environment perceived by high school students. This research endeavor constitutes a developmental study, wherein the outcomes…

The aim of this research is to adapt the 24-item "Learner Autonomy Scale" developed by Sereti and Giossos (2018) in higher education samples into Turkish by examining the psychometric properties of high school and secondary school samples, and to determine whether these groups are equivalent in terms of measurement invariance. The scale…

The insertion of Machine Learning (ML) in everyday life demonstrates the importance of popularizing an understanding of ML already in school. Accompanying this trend arises the need to assess the students' learning. Yet, so far, few assessments have been proposed, most lacking an evaluation. Therefore, we evaluate the reliability and validity of…

Given the importance of mathematics identity for students continued participation and engagement with mathematics, it is important for educators and researchers to be able to explore students' mathematics identity development. However, an instrument with validity evidence that can be used to explore mathematics identity efficiently and with groups…

Assessing students' perceptions of the services provided by school counselors is crucial in promoting these services. However, there is no reliable scale for this assessment in the Persian language to date. Thus, this study aimed to translate and validate the School Counselor Noncognitive Skills Scale (SCNSS) among Iranian high school students.…
