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.…

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.…

The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

The aim of this study was to adapt the Positive and Negative Affect Scale for Children (PANAS-C) developed by Laurent et al. into Turkish and to examine its validity and reliability on high school adolescents. The data of the study were analyzed with four different study groups. The first study group consisted of 414 high school adolescents, 262…

Anger is a topic that requires intervention from teachers, counsellors, psychologists, parents, and all communities. The expressions of anger are subjective and sometimes hard to identify. Thus, anger should be measured more objectively, while the expressions need to be examined closely. The purpose of this study is to provide valid confirmation…

This study aimed to analyze the relationship between understanding Indonesian history, multiculturalism, and historical awareness with the nationalist attitudes of state high school students in Yogyakarta. This type of research was correlational research with a quantitative approach. The sample consisted of 126 students. Data collection used tests…

This paper explores the spatial dimension of Fleming's Left Hand Rule (LHR), commonly-used in Physics instruction for determining the direction of force using the left hand's thumb, forefinger and middle finger. A new instrument was developed to gauge students' ability to coordinate their fingers in 3D space (egocentric frame of reference) based…

Previous work has focused on positive feelings of mattering, which pertain to the human need to feel significant. In the current article, we examine a complementary yet distinct construct involving feelings of not mattering that may arise from being marginalized and experiences that heighten a sense of being insignificant to others. We also…

When cognitive and educational tests are administered under time limits, tests may become speeded and this may affect the reliability and validity of the resulting test scores. Prior research has shown that time limits may create or enlarge gender gaps in cognitive and academic testing. On average, women complete fewer items than men when a test…

The purpose of this study is to develop an up-to-date scale with high validity and reliability that could reveal the attitudes of high school students towards the physics course. In the process of developing the scale in question, three independent samples were formed, and the data obtained from a total of 1118 high school students were analyzed.…

With the study reported on here we aimed to explore the relationship between situational determinants of teachers' perceptions of organisational politics in some public high schools in the KwaZulu-Natal province. We adopted a crossregional survey design and convenience sampling to study teachers (n = 301) at public high schools in all 10 districts…

Teacher-student relationships have been studied with increasing intensity during the past three decades, but the majority of this study has focused on young children and has relied on teacher perceptions of these relationships. The current study was designed to add to this growing body of research by exploring the factor structure, reliability,…

Logical reasoning as part of critical thinking is becoming more and more important to prepare students for their future life in society, work, and study. This article presents the results of a quasi-experimental study with a pre-test-post-test control group design focusing on the effective use of formalisations to support logical reasoning. The…

To measure the procedural and conceptual knowledge of functions and to clarify the relationship between them in the context of mathematics education in Morocco, a structural equation modeling (SEM) analysis was used. In addition, correlation tests between students' grades at their Mathematical Analysis Assessments and their procedural and…

The recent results of the Education First English Proficiency Index (EF EPI) showed that the country placed seven spots lower compared to the past ranking. The purpose of this study is to determine the level of competence of students in grammar and academic writing and to find out if a significant relationship existed between the variables. This…
