The study established the validity and reliability of a weighted individual performance-based assessment tool within the utility scope of middle school orchestral strings. The following research questions guided this study: 1. What specific string-playing behaviors and corresponding criteria validate a weighted individual performance-based…

The Social Emotional Health Survey-Secondary-2020 (SEHS-S-2020) is a well-studied option for assessing social emotional health to support students within a multitiered system of school support. While a growing body of literature supports the SEHS-S-2020 measure for assessing student covitality, there is less validation evidence specifically for…

This study presents an exemplar for psychometric evaluation and modification of established measures when applied to new populations. Specifically, we describe the use of two subscales (Career Decision-Making Self-Efficacy Scale and Math/Science Self-Efficacy Scale) from the Middle School Self-Efficacy Scale (MSSES) as outcome measures in an…

The main objective of this study is to revise and validate the assessment of self-presentation skills of middle school students. The assessment is based on existing self-assessment scales and adaptively modified for a more accurate assessment of middle school students' self-presentation skills. Considering the characteristics of middle school…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

This study developed an Adolescents' Uncertainty Scale (AUS), with the aim of understanding individual differences in uncertainty among adolescents. In the pretest phase, 507 ninth-grade students were recruited. After exploratory factor analyses, a 25-item AUS with four dimensions--irresoluteness, instability, lack of self-knowledge, and…

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…

Rubrics are popular tools to assess students' social-emotional skills. However, little research has been devoted to investigating whether rubrics' performance level descriptions validly represent the intended skills. In this study, we addressed the validity of Self-management rubrics by examining the presence of construct-irrelevant variance in…

This study aimed to develop a STEM module for eighth-grade middle school learners through the engineering design process. The module was developed based on the ADDIE model, primarily concentrating on the stages of analysis, design and development. The study consisted of two main phases: module development and module evaluation. During the…

Interdisciplinary thinking is critical for equipping students to apply scientific knowledge and tackle societal challenges across various disciplines, which has been recognized as a key objective of twenty-first century science education. However, research on effective interdisciplinary assessment in secondary school science education is still…

Purpose: The purpose of this study is to develop a valid and reliable scale that can measure the level of respect for differences of middle school students. The validity and reliability studies of the scale draft prepared as a result of the opinions received were carried out on 964 middle school students. Design/methodology/approach: The…

Compared to other content areas, there is a dearth of research examining curriculum-based measurement of writing (CBM-W). This study conducted a conceptual replication examining the reliability, stability, and sensitivity to growth of slopes produced from CBM-W. Eighty-nine (N = 89) eighth-grade students responded to one CBM-W probe weekly for 11…

This study aimed to develop a valid and reliable multiple-choice achievement test for the subject area of ecology. The study was conducted within the framework of exploratory sequential design based on mixed research methods, and the study group consisted of a total of 250 middle school students studying at the sixth and seventh grade level. In…

Despite the high demand for STEM (science, technology, engineering, and mathematics) professionals, the STEM talent pipeline continues to leak. A framework of STEM identity could provide insight into why and to what extent individuals engage in STEM-related activities. The present study describes the process of developing and validating an…

Diagnostic tests have been developed previously to measure algebraic thinking skills; however, the tests do not specifically address algebraic problem-solving. Thus, an Algebraic Thinking Test (ATT) Instrument was developed to measure algebraic thinking skills in problem-solving involving linear equations. ATT comprises nine open-ended questions…
