This study developed and validated the Science Practice Scale (SPS) and investigated the implementation of scientific teaching practices by Grade 8 science teachers in Jordan. The responses of 235 8th grade science teachers who participated in the Trends in International Mathematics and Science Study [TIMSS] of 2019 were analysed using the Rasch…

Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

The current study serves two basic purposes: (1) to develop and validate a scale designed to examine students' mobile learning acceptance behavior in mathematics, and (2) to examine factors that influence their intentions to use mobile learning in their future. The Unified Theory of Acceptance and Use of Technology (UTAUT) was the theoretical…

This study evaluated the construct validity of six scoring traits of an automated writing evaluation (AWE) system called "MI Write." Persuasive essays (N = 100) written by students in grades 7 and 8 were randomized at the sentence-level using a script written with Python's NLTK module. Each persuasive essay was randomized 30 times (n =…

The main aim of this study is to develop a useful, valid, and reliable two-tier proportional reasoning skill test for middle school 7th and 8th-grade students. The research was carried out using the sequential explanatory mixed method. The study group of this research comprised of 391 (n[subscript 7th-grade]=223, n[subscript 8th-grade]=168)…

This study's purposes were to develop a rating scale for midlevel band performance and validate a theoretical structure for the scale. Research questions were (a) What qualities describe excellent seventh- and eighth-grade band performance? (b) What items constitute a Midlevel Band Performance Rating Scale (MBPRS)? (c) How reliable is the MBPRS?…

This study aims to design mathematical literacy instruments that have evidence of content and construct validity and are reliable for use as an assessment for learning. The research involved eight experts as instrument validators and 273 eighth-grade students of junior high school in Yogyakarta Province. The results showed that the ten…

Purpose: The research aimed to examine the construct validity of a scientific-mind measurement model for secondary school students in Bangkok and the factor loading values of scientific-mind indicators. Methodology: Stratified random sampling was used to select a sample of 500 Grade 8 students studying in a Bangkok school district during the 2016…

This study classifies the verbal feedback of science teachers into praise statements, effort-based feedback statements, negative feedback statements, and ability-based statements, which are also regarded as feedback strategies. The study aims to investigate the feedback strategies used by science teachers in the classroom setting using descriptive…

Given the increasing emphasis of communicative competence in English as a foreign language (EFL) contexts and the lack of validation research on speaking assessments for adolescent EFL learners, in the current study we examined the validity of the TOEFL Junior® speaking test, a relatively new speaking assessment developed by Educational Testing…

Wording effects associated with positively and negatively worded items have been found in many scales. Such effects may threaten construct validity and introduce systematic bias in the interpretation of results. A variety of models have been applied to address wording effects, such as the correlated uniqueness model and the correlated traits and…

The present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N = 817), Confirmatory Factor Analyses (CFA) were…

A scale for measuring self-efficacy for teaching mathematics in grades 5 to 10 was developed in this study for teachers in Oman. The participants were 328 mathematics teachers randomly selected from five educational governorates in the Sultanate of Oman. Factorial structure of the scale revealed three subscales: self-efficacy for understanding the…

The literature regarding teamwork has supported the idea that the key to improving team performance is to understand team processes. Early work within the realm of teamwork focused on quantifiable measures of team performance, like number of products developed. The measure of a successful team hinged on whether or not the team accomplished the end…

The aims of this study are to: (a) assess if cognitive self-concept (competence) and affective self-concept in mathematics and science are different constructs, (b) evaluate the construct validity of self-concept in the context of conflation and separation, and (c) test if the relationships among cognitive and affective variables are invariant…
