This study aimed to evaluate the psychometric properties and gather evidence supporting the validity of scores from a traditional Chinese version of the Claremont Purpose Scale (TC-CPS) among Taiwanese adolescents. The TC-CPS, measuring meaningfulness, goal directedness, and beyond-the-self orientation, was administered to 233 high school and 445…

Background/purpose: This study aimed to investigate the differences among the equations used in estimating the reliability coefficient using the half-split method. These equations demonstrate Spearman-Brown's, Rulon's, Guttman's, Mosier's, Flanagan's, and Horst's. Materials/methods: The study instrument was a 43-item scale for evaluating the…

Technological mediation has gained relevance in teaching mathematics. Its usefulness and impact depend, to a great extent, on how students approach the learning of the discipline. Two independent instrumental studies were conducted to analyze the psychometric properties of the Spanish version of the Mathematics and Technology Attitudes Scale…

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…

Assessment in education involves collecting and processing information related to student achievement during learning. Assessment activities help educators to find out where learners are having difficulties which for the sake of completeness requires an integrated instrument. The assessment carried out should conform to 21st-century learning…

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.…

The current study aimed to create and validate a digital literacy assessment tool's quality for students in Grades 10-12 within the Thai educational context, and 2) to develop T-score norms derived from the results of the digital literacy assessment tool for students in Grades 10-12 in this context. The study followed a research and development…

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 =…

Cultural variations in affective experiences are observed. Research on positive affect with refined categorizations has been limited. This study examined the Affect Valuation Theory and its measure, the Affect Valuation Index (AVI), using a sample of high school students from rural China (N = 676, M[subscript age] = 16.17 years, SD = 0.94). The…

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. In the absence of validated instruments to measure this construct, this study has focused on designing and validating a "Measurement Scale for the Social Appreciation of Cultural…

Purpose: Research documents poor outcomes for autistic adults in the domains of employment, independent living, and social relationships. Measurement and sample limitations in prior studies may have amplified past estimates of poor outcomes. The goal of the current study was to improve upon past approaches and to create and describe a measurement…
