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 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…

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…

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…

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…

The problem addressed by this study was to determine the influence of high school start times on students' academic achievement and precisely how this impacts the scores students received on the Biology I End of Course Exams. It also determined if there was a difference in influence between males and females. This was determined by comparing the…

Student science proficiency development demands sustainable and coherent learning environment support. Scholars argue that project-based learning (PBL) is an efficient approach to promoting student science learning, compared to conventional instructions. Yet, few studies have delved into the learning process to explore how a coherent PBL system…

When individuals' attention shifts away from the primary tasks they are involved in, their minds start to wander. This mental phenomenon, also known as mind-wandering, can interact with other variables and affect the performance of academic tasks. The current study focuses particularly on the mind-wandering (MW) of Omani students while they were…

The significance of the role of students' interpretation and creation of multiple forms of representation in science learning has long been established and advocated, but there is a paucity of research into the extent to which this emphasis in science education is reflected in high stakes final year high school science examinations. This study…

Enrollment in high school physics across the United States of America is notably lower than in other scientific disciplines. Given that physics serves as a prerequisite for admission into many STEM (Science, Technology, Engineering and Mathematics) degree programs, the lack of completion of this course at the high school level can significantly…

The aim of this study is to develop a valid and reliable achievement test on the subject of 'Basic Compounds in the Structure of Living Things'. During the preparation of the draft form of the test, a 32 item-question pool was created by the researchers in the light of the relevant literature. Then, these questions were presented to expert opinion…

The purpose of this study is to demonstrate clustering methods within a functional data analysis (FDA) framework for identifying subgroups of individuals that may be exhibiting categories of misfit. Person response functions (PRFs) estimated within a FDA framework (FDA-PRFs) provide graphical displays that can aid in the identification of persons…

This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

In this study, we explore the use of analogies with classical physics in introductory quantum physics (QP) teaching. This work is part of a larger project in which a learning sequence covering three introductory QP topics was designed, tested, and evaluated in collaboration with high school teachers and physics education researchers. Based on the…

This study aims to determine Turkish high school students' misconceptions about the electric charge imbalance by using a four-tier misconception test, where the main questions are accompanied by a question about the reason for the answer, as well as student declarations about their degrees of certainty. A four-tier electric charge imbalance…
