This study aimed to develop a standardised instrument for diagnosing science misconceptions in primary school children. Following a developmental research approach using the 4-D model (Define, Design, Develop, Disseminate), 100 four-tier multiple choice items were constructed. Content validity was established through expert evaluation by six…

In this study, it was aimed to develop an achievement test taking into account the subject acquisitions of the sound and properties unit in the sixth-grade science course. In the test development phase, firstly, literature review for the study was conducted. Then, 30 multiple choice questions in align with the subject acquisition in the 2018…

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,…

Developing tools to identify students' misconceptions about basic biology concepts is necessary. Therefore, a two-tier diagnostic test was developed to determine such misconceptions in primary school (3rd-4th Grade) students. The test content includes two-tiered multiple-choice questions addressing common misconceptions found in the literature on…

The assessment of test anxiety has received increasing attention in educational research due to the potential negative effects of anxiety on student performance. Traditionally, test anxiety scales have been developed for mathematics, but few studies have focused on physics. In this study, we validated two test anxiety scales for undergraduate…

This study aimed to develop an instrument with acceptable validity and reliability for assessing two key aspects among science teachers: their self-efficacy in teaching science through an integrated STEM approach (STSIS) and their outcome expectancy when employing this approach (OETSIS), which we refer to as TSTSIS. We administered this tool to…

Identifying a student's mental model is important for understanding scientific concepts. Dispersion and polarization are the sub concept of physics that studied in high school on light waves concept. This study aimed to develop dispersion and polarization conceptual inventory (DIPOLCI) to identify students' model mental using Rasch analysis. The…

The accurate assessment of analytical thinking in physics, particularly in magnetism, poses substantial challenges due to the limitations of conventional tools in measuring higher-order cognitive skills. This study aimed to validate an analytical skills test in physics, based on Bloom's Revised Taxonomy, with an emphasis on the dimensions of…

This current study presents the effects of interactive computer simulations on students' performance and concept retention in the unit of chemical reactions. Purposive sampling was used to select four schools with a sample population of 320. The Achievement test on chemical reactions was developed, validated, and checked for reliability. The…

In the last 30 years, 4 distinct theoretical approaches have been described for early childhood science education. The approaches are, empiricist, Piagetian, socio-cognitive and socio-cultural. Drawing on the differences among these approaches regarding the theoretical framework adopted in teaching, the role that is assigned to the teacher during…

Alternative conceptions become obstacles in physics. However, it is difficult to find instruments that can identify students' alternative conceptions, especially in gases kinetic theory (DIGaKiT). The purpose of this research was to development of diagnostic instrument of DIGaKiT in identifying students' alternative conceptions by Rasch analysis…

The Survey of Physics Reasoning on Uncertainty Concepts in Experiments (SPRUCE) was designed to measure students' proficiency with measurement uncertainty concepts and practices across ten different assessment objectives to help facilitate the improvement of laboratory instruction focused on this important topic. To ensure the reliability and…

The increasing and diversifying student enrollments in introductory physics courses make reliable, valid, and usable instruments for measuring student skills and gains ever more important. In introductory physics, in addition to teaching facts about mechanics, we also seek to teach our students the skills of "thinking like a physicist,"…

The aim of this study is to develop a valid and reliable scale to determine the attitudes towards the activities that can be applied to the mentally retarded students about biology and nature. During the preparation of the draft form of the scale, an item pool was created from relevant literature. Then, these items were presented to expert opinion…

This study aimed to develop a two-tier light concept test to identify student concept understanding of light. The development of the test was carried out through the content validity, construct validity, and reliability test stages using the Item Response Theory (IRT). The sample consisted of 81 students during the second semester at five…
