Past studies of grit's educational benefits, such as science engagement, showed mixed results across cultures. So, we elaborated the prior model of grit (perseverance of effort, consistency of interest) with "adaptability to situations" (forming a "triarchic model of grit" TMG), and tested TMG's relation to subsequent science…

Student absenteeism is a persistent concern in K-12 education. Not only are the negative academic and social consequences of excessive absenteeism well documented, but states, districts, and schools are increasingly being held accountable for student attendance. As research indicates that disruptions in students' learning contexts may exacerbate…

Stability and change in students' achievement goals (AGs) are of great relevance for educational research and practice. In two separate meta-analyses, we investigated the rank-order stability (93 studies, 569 effect sizes, 54,736 students), as well as the mean-level change (157 studies, 1,170 effect sizes, 81,464 students) in AGs throughout…

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…

Research has focused on the various reasons why high school principals leave their positions, yet minimal research has been done on the reasons why they stay. The problem of inconsistency of high school principals' tenure within the first 4 years of service was addressed in this study. Deci and Ryan's self-determination theory was used in this…

The study aims to verify the validity and reliability of a set of tests for measuring Indonesian students' reading literacy achievement that has been developed by the Center for Language Strategy and Diplomacy Development as well as the Educational Assessment Center, two institutions under the auspices of the Ministry of Education, Culture,…

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 is the sixth and culminating study in a series whose purpose has been to acquire a conceptual understanding of school band performance and to develop an assessment based on this understanding. With the present study, we cross-validated and applied a rating scale for school band performance. In the cross-validation phase, college students…

Shame is a significant factor for psychological problems in adolescents. The present study aims to assess the Persian version of the Adolescent Shame-Proneness Scale (ASPS) among Iranian adolescents. Participants of this correlation study were 2291 high school students aged 12-18 (1296 girls and 1036 boys), selected through a multistage random…

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…

This study aims to develop a scale to determine the Teachers' Management of Undesirable Student Behaviours. The study to determine the construct validity and internal consistency was carried out in the general screening model. The study groups consist of 822 students (458 for AFA; 364 for DFA) studying at various high schools in the centre and…

This study contributes to the call for influencing practice by increasing attention to how learning environments can be designed to support learning in statistical inference. We report on a design experiment in secondary school (students 14-16 years old), that resulted in a set of lessons with the learning goal of teaching students how to apply…

The research's aim is to assess the services offered by Greek public secondary education schools, with the intention of identifying any discrepancies between students' expectations and their perceptions of the final services provided. The gaps discovered indicate that the school's educational services are not meeting student expectations in the…

Students' science literacy abilities must receive special attention, particularly by investigating root causes and implementing strategies for improvement. Measuring science literacy through questions is crucial to determine students' proficiency to be science literate. This research aims to produce higher-order thinking skill (HOTS)-based science…

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…
