Sound waves are one of the important topics studied in physics. However, students' graph representation is still low, leading to their low concept understanding of physics learning. Therefore, it is necessary to optimize the learning process to improve students' graph representation by providing a valid and reliable graph representation test…

This study focuses on developing a five-tier chemical diagnostic test based on a computer-based test with 11 assessment categories with an assessment score from 0 to 10. A total of 20 items produced were validated by education experts, material experts, measurement experts, and media experts, and an average index of the Aiken test > 0.70 was…

Recently, psychometricians and researchers have voiced their concern over the exploration of language test items in light of Messick's validation framework. Validity has been central to test development and use; however, it has not received due attention in language tests having grave consequences for test takers. The present study sought to…

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…

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,…

Socially regulated learning (SoRL) is a critical mechanism for enhancing the effectiveness of collaborative learning outcomes. Measurement of university students' engagement in SoRL is essential for refining the strategies aimed at improving its efficacy. Nonetheless, the measurement of university students' levels of engagement in SoRL remains…

It is known that students have many misconceptions about concepts related to function. By discovering misconceptions using an appropriate measurement instrument, we can determine what changes we need to make in the real functions curriculum to improve learning outcomes. Therefore, we designed an item bank for measuring conceptual understandings of…

Researchers design diagnostic assessments to measure students' knowledge structures and processing skills to provide information about their cognitive attribute. The purpose of this study is to determine the instrument's validity and score reliability, as well as to investigate the use of classical test theory to identify item characteristics. The…

This paper presents the findings of a study that intended to seek the content validity (CV) evidence of an instrument to measure the reading ability of university students in Sri Lanka. The reading passages and items were adapted from CEFR aligned Learning Resource Network (LRN) materials. The items were designed based on the cognitive processing…

The teaching of English as a foreign language in Indonesia has a long history, and it is always important to ask whether the assessment of the students' language skills has been valid and reliable. A screening of many articles in several prominent databases reveal that a number of evaluation studies have been done by Indonesian scholars in the…

This study provides the development phases and initial psychometric evaluation of the Integrated Care Competency Scale (ICCS) with sample (n = 243). Specifically, quantitative methods with graduate counseling students were used in this study. The ICCS through a three-phase study process was honed to 65 items and broadly assesses graduate…

Teacher-developed test, in the form of multiple-choice questions has widely used for measuring the students' final learning process. Content validity and items analysis is used to evaluate the quality of the test that is developed by the teacher. The study focused on content validity that analyzed the content of the test and basic competency which…

In this study, a 'biotechnology literacy test' was developed to determine the biotechnology literacy of prospective science teachers, and its validity and reliability were determined. For this purpose, 42 items were prepared by considering Bybee's scientific literacy classifications (nominal, functional, procedural, and multidimensional). The…

In German Switzerland the learning and assessment of Swiss German Sign Language ("Deutschschweizerische Gebärdensprache," DSGS) takes place in different contexts, for example, in tertiary education or in continuous education courses. By way of the still ongoing implementation of the Common European Framework of Reference for DSGS,…

Concept inventories (CIs) are valuable tools for educators that assess student achievement and identify misconceptions held by students. Results of student responses can be used to adjust or develop new instructional methods for a given topic. The regulation of gene expression in both prokaryotes and eukaryotes is an important concept in genetics…
