Educational researchers often need to construct precise and reliable measurement scales of complex and varied representations such as participants' written work, videoed lesson segments and policy documents. Developing such scales using can be resource-intensive and time-consuming, and the outcomes are not always reliable. Here we present…

The purpose of this study was to develop a reliable and valid rating scale for the use of the assessment and evaluation of lesson plans and teaching practices that are based on argumentation-based inquiry (ABI). The study covered two academic years (four academic semesters). Qualitative and quantitative methods were utilized throughout the…

This study aimed to develop a parent rating scale (PRSG) for screening children for further identification process in terms of giftedness. The participants of the study were 255 parents of gifted and non-gifted students. The PRSG, consisting of 30 items, was created by consulting parents and reviewing instruments existent in the literature. As…

Peer evaluation consists of the evaluation of students by their peers following criteria or rubrics provided by the teacher, where the way to evaluate students is specified so that they achieve the desired competencies. The quality of the measurement instrument must meet two essential criteria: validity and reliability. In this research, we…

The Content Proximity Project was designed to improve the content validity of the MAP® Growth™ assessments while retaining the ability for the test to adapt off-grade and meet students wherever they are in their learning. Two main features of the project were the development of an enhanced item selection algorithm, and a spring pilot study…

The progress of the nation is based on the competencies of the citizens, and the overall development of the person depends on the effectiveness of the educational system implemented in the country. The teacher is a key factor in the implementation of educational programs. Without a favorable attitude toward the teaching profession, teachers cannot…

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.

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…

This study provides preliminary evidence for reliability and validity of the Hawaii Early Learning Profile Strands 0-3 (HELP Strands 0-3), an assessment instrument for young children. First, the degree of interobserver agreement for a sample of representative HELP items was examined; results indicated that HELP scoring was dependable and…

Purpose: This study aims to assess the validity and reliability of the Psycho-B'GREAT Module developed according to the ASSURE's Module Development Model. Method: The content validity of the Psycho-B'GREAT Module was assessed by ten experts in the fields related in teaching and learning (T&L) and biology education. In testing the…

In evolution education, misconceptions about evolutionary concepts impact students' learning. Much research exists on assessing knowledge about evolution using different instruments. The current article introduces the KAEVO 2.0 instrument, which includes various evolutionary aspects representing microevolution and macroevolution. The introduced…

Science, technology, engineering, and mathematics (STEM) influence almost every aspect of our daily lives. However, despite the high demand for STEM occupational talent, the STEM pipeline continues leaking, with less than one-sixth of high school students pursuing STEM majors and only 50% of entering STEM majors matriculating into STEM fields.…

The Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) is used to assess auditory development in young children with hearing loss. Despite being widely used, previous research showed that its psychometric properties are not ideal. As a first step toward psychometric advancements of the IT-MAIS, this study aimed to create videos with…

To be familiar with micro and symbolic performances, students could work out more effective approaches of innovated techniques known as five hierarchical designs in chemistry equilibrium. However, the most frequently reported problem in students' assessment of chemistry study is attributed to their poor skill recognizing basic concepts. The aim of…

Integrated STEM education holds the promise for students' meaningful science instruction. However, the implementation of integrated STEM-based approaches for science learning might be difficult for teachers due to the lack of expertise and instructional materials. Therefore, this study focused on the preparation and validation of an integrated…
