This study aimed to develop a comprehensive diagnostic tool for assessing upper-secondary school students' understanding of isomers, expanding upon existing two- and three-tier conceptual diagnostic methods. By incorporating 'Confidence Rating Factor' tiers within the answer and reason sections, a four-tier test was designed and developed. This…

This article provides a process to carefully evaluate the suitability of a content domain for which diagnostic classification models (DCMs) could be applicable and then optimized steps for constructing a test blueprint for applying DCMs and a real-life example illustrating this process. The content domains were carefully evaluated using a set of…

Scientific literacy is an organizing principle for K-16 education but is notoriously difficult to operationalize. This study provides a list of instruments that measure aspects of Vision II scientific literacy, or science for citizenship. Based on the definition of scientific literacy by the National Academies of Sciences, Engineering, and…

Previous studies noted the scantiness of diagnostic instruments for the assessment of students' understanding of fundamental biochemistry concepts. Consequently, within this study, a four-tier test for the examination of secondary school students' conceptual understanding of amino acids, proteins, and enzymes has been developed. Items in the test…

The main objective of the present study was to construct and standardize an achievement test in science for the secondary school science students in grade 8. An achievement test having 120 test items was prepared by the facilitator based on the four main learning objectives of teaching science that are knowledge, understanding, application, and…

This study aims to obtain and compare the opinions of exam question writers and teachers on skill-based exam questions. 24 science teachers and 11 context-based exam question writers participated in the study, which was carried out according to the convergent parallel design. Opinions of both parties on the skill-based exam questions were…

This study examines the relationship between two secondary End of Course (EOC) exams, the Biology EOC and the English I EOC exams, and their impact on Emergent Bilingual (EB) students in a small district in South Texas. This study is a mixed methods study which uses both quantitative and qualitative data to answer three research questions: (a)…

Science classroom assessment often requires multilingual learners to demonstrate ideas using only English-language resources. These assessments can provide an incomplete picture of students' knowledge and limit subsequent learning opportunities. Increasingly, science teachers are incorporating translanguaging pedagogies in their instructional…

Background/Context: In order to stimulate national and regional economic growth, policymakers and businesses have expressed great interest in growing the supply of workers with skills in science, technology, engineering, and math (STEM). At the same time, considerable efforts are being devoted to narrowing race and gender gaps in the STEM training…

Predicting student performance in international large-scale assessments (ILSAs) is crucial for understanding educational outcomes on a global scale. ILSAs, such as the Program for International Student Assessment and the Trends in International Mathematics and Science Study, serve as vital tools for policymakers, educators, and researchers to…

The objectives of this research are: (1) to develop a flipped classroom learning plan using inquiry-based learning on the topic of substance separation for Grade 8 students, to achieve effectiveness according to the 75/75 criteria; (2) to compare science process skills and learning achievement before and after implementing the developed learning…

Procedural and conceptual e-scaffolding has been shown to be effective for assisting novice learners in understanding new concepts. Its integration with modelling instructions (E-MI) raises expectations for improving scientific reasoning (SR) in students whose level is still a concern in Indonesia. A quasi-experimental study was conducted to find…

Background/purpose: Science education has gained more prominence as a means of educating students for the demands of a technologically evolved world. Understanding the variables influencing students' science achievement is vital for educational policymakers and practitioners. Materials/methods: The study used a hierarchical multiple regression…

STEM education has experienced significant growth due to its pivotal role in innovation and economic development. While cognitive factors like prior knowledge are known predictors of STEM success, non-cognitive factors, including attitudes and demographics, also play vital roles. However, there is a notable scarcity of research focusing on the…

Biology education research has shown that deeply rooted intuitions can influence students' understanding of biological phenomena. One example is design teleology, the intuition that organisms' traits were designed to fulfill a goal. Another example is psychological essentialism, the intuition that organisms have fixed essences. Past research has…
