This article focuses on the validity of the students' attitudes toward mathematics scale based on data from TIMSS 2019. The scale has been reported as having a three-factor structure for decades, but this study assumes the validity can appear differently depending on the country or culture. Thus, the scale should first be checked for invariance…

Purpose: Given the scientific and practical difficulties inherent in measuring and comparing socioeconomic deprivation (SED), and the further complexity added in cross national measurements, the main aim of this paper was to check the validity of SED measures used in PISA 2018 dataset. The SED measure used in PISA 2018 was the PISA index of…

This study was aimed at developing and validating a scale that measures the emotions of secondary school students toward Biology. Before selecting a particular subject, it is very important to measure student's emotions toward that subject. The emotions were measured in two academic contexts: class-related and learning-related situations. The…

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…

Personal (PSs) and professional (PRs) skills are necessary to any physical education (PE) teacher, potentially having an impact on the quality of teaching and students' engagement in PE. In recent years, the Teachers' Personal and Professional Skills Questionnaire (TPPS-Q), composed of two 5-item dimensions (PSs and PRs), has been developed and…

The authentic research experience, which provides students with meaningful collaborative research opportunities designed to promote discovery and innovation under the guidance of mentors, is increasing as a way to attract and engage students in STEM fields. However, despite the increase in authentic research experiences offered to students, there…

Academic grit can be a student's rock-solid confidence to maintain focus and go on learning despite obstacles in the way of achieving their long-term goals. This investigation into points to develop an academic grit scale and determine the variables that underlie students' academic grit will help to construct a significant and reliable tool for…

This was the first study in which a psychometrically validated STEM measure, the "Student STEM" (S-STEM), was studied for HSSWD. This study also represented the first time a psychometrically validated STEM measure, the "Student STEM" (S-STEM), was studied for HSSWD. Data were collected from 229 HSSWD in a western state and…

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 =…

Purpose: Drawing on current theoretical perspectives on teaching methods (i.e., constructivism, cognitivism, or behaviorism), the present research developed a scale to assess students' perceptions of teaching methods in physical education. Method: Four studies were conducted to design and analyze the psychometric properties of this scale: (a) to…

In England, Wales and Northern Ireland, the General Certificate of Secondary Education (GCSE) has been for the last 35 years the most common qualification by which students' attainment at age 16 has been measured. The range and balance of processes by which the GCSEs' programmes of study have been assessed have varied over the decades, to include…

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…

Climate change worry (CCW) is a specific worry about climate change, involving thoughts about changes that might occur in the climate system and their possible effects. Nowadays, it is growing especially among adolescents. As there is a lack of measurement tools with adequate psychometric properties to assess CCW in this age group, we investigated…

This study aims to determine the development and feasibility of biology magazine submaterial inheritance traits as a learning media for class IX junior high school. Engaging and effective learning media can increase students' understanding and interest in the material presented. The research method used is research and development (R&D) using…

Growth mindset in mathematics is an approach to teaching mathematics, believing that students' abilities can be developed with efforts, strategies, and support. With a sample of 178 middle school students, this study proposed a scale for mathematical mindset utilizing Boaler's positive norms in teaching mathematics and collected evidence for…
