The present study has aimed to develop and validate a protein concept inventory (PCI) consisting of 25 multiple-choice (MC) questions to assess students' understanding of protein, which is a fundamental concept across different biology disciplines. The development process of the PCI involved a literature review to identify protein-related content,…

Title I accountability requirements under the Every Student Succeeds Act (ESSA) represent the present-day instantiation of Lau, which requires schools to provide a program for English learners (ELs) that supports their meaningful engagement and to provide transparent information about EL program quality. This study uses critical policy analysis to…

Validity is broadly defined as how well something measures what it's supposed to measure. The reliability and validity of scores from assessments are two concepts that are closely knit together and feed into each other.

In this study, a valid and reliable scale (TSSSSS) was aimed to develop to measure secondary school students' perceptions of teacher support. The research was carried out on a total of 773 students studying in 6 different secondary schools in Ankara's Yenimahalle district in the Spring Term of the 2021-2022 Academic Year. The students who…

As higher education institutions adopt blended learning, administrators play a crucial role in implementing and supporting blended learning, ensuring its success (Lomonosova & Valentinovna, 2018). The study investigates administrators' perceptions of blended learning as a teaching strategy, using a proportionate sampling sample and a content…

Validity evidence based on test content is critical to meaningful interpretation of test scores. Within high-stakes testing and accountability frameworks, content-related validity evidence is typically gathered via alignment studies, with panels of experts providing qualitative judgments on the degree to which test items align with the…

The aim of this study was to develop and validate the Childhood Nonverbal Communication Scale (CNCS) to assess nonverbal communication skills in children from birth to 18 months old. An extensive review of existing research provided evidence used to generate items representative of nonverbal communication behaviors. The final version of the CNCS…

The current paper aims at developing and validating a Teacher Leadership Inventory (TLI). Adopting the theoretical-empirical strategy of instrument development, the procedure consisted of taking a sample of panel experts and undertaking six sequential empirical studies with sufficient samples of teacher leaders from China. After verifying content…

Many researchers have separately developed instruments to measure environmental characteristics such as attitudes, values, and knowledge. However, there is no instrument used to measure all these aspects in one comprehensive instrument. This study is meant to develop and validate a green character instrument which reveals student behavior and…

As community-based service-learning becomes more widely used in occupational therapy (OT) education, valid and reliable outcome measures are needed to ensure that student learning outcomes are meaningfully and consistently measured. Currently, educators may use instructor-developed questionnaires that have not been validated or employ narrowly…

As the existing questionnaires did not fit the type of analysis that is intended to carry out, a…

Direct Behavior Rating (DBR) is an efficient method for monitoring changes in student behavior in response to intervention. Emerging research on DBR Multi-Item Scales (DBR-MIS) indicates that DBR-MIS has promising characteristics as a progress-monitoring assessment. Specifically, the multiple items within DBR-MIS allow stakeholders to measure…

The purpose of this research was to develop a curriculum design evaluation instrument in strengthening Al-Irsyad ideology. The research activity began with a literature review on the curriculum then continues with the development of the instrument. The results of the development of the instrument items were validated by 11 experts and tested on a…

Low levels of critical thinking skills and learning motivation, particularly in physics learning, pose significant challenges that must be promptly addressed to ensure students' future success. To tackle this issue, the present study endeavors to develop a Cooperative Model, Digital Game, and Augmented Reality (CAP)-based learning, which is both…

Intelligence has been extensively explored across various disciplines such as psychology, cognitive science, and neurology. Countless scholars have delved into understanding why certain individuals exhibit higher mental acuity and knowledge. Consequently, numerous studies aim to unveil the essence of intelligence and gauge human cognitive…
