While previous research has shown that claim-evidence-reasoning can effectively promote higher-order thinking skills in science education, more research should be done on using claim evidence-reasoning in elementary school settings. This study aims to investigate the effectiveness of claim-evidence-reasoning in promoting the scientific reasoning…

Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists' work and key suggestions for teaching through modeling. The lesson "The Structure and Function…

University courses are often interconnected; however, the connections between these courses remain unclear to many students. This is particularly important in the field of forensic science since each stage of the investigation, from the crime scene to the courtroom, has significant implications on the outcome of a case and the individuals…

This study examined the effect of design-based science instruction (DBSI) on sixth grade students' science achievement, as well as their development in relation to science process skills. 213 sixth grade students from three public schools participated in the study. A pilot was conducted in the unit of Systems of the Human Body and the main study…

The science process skills of elementary school students in Langsa city are still relatively low, despite these skills being a crucial element in science education based on the Merdeka curriculum. Additionally, teachers have reported several challenges, including the presence of abstract science material, textbooks that use two-dimensional…

[This paper is part of the Focused Collection on Qualitative Methods in PER: A Critical Examination.] Identifying student ideas about particular physics topics is one of the earliest and longest-standing foci of physics education research. This paper presents a method for identifying common conceptual resources for understanding physics, using…

This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

Preparative chromatography is one of the most common and important purification techniques in organic chemistry and is employed in laboratories across the globe. In order to facilitate student proficiency with the method, a unique approach for the separation of estragole, ethyl cinnamate, and cinnamyl alcohol using microscale preparative flash…

We use a validated conceptual multiple-choice survey instrument focusing on thermodynamic processes and the first and second laws of thermodynamics at the level of introductory physics to investigate the problem-property dependence of introductory and advanced student responses to introductory thermodynamics problems after traditional…

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to…

The COVID-19 pandemic necessitated changes in educational strategy, including modification of assessments. Students in the Master of Biomedical Sciences (MBS) program at Duke University School of Medicine are required to take a course entitled "Organ Systems" (OS), which includes organ histology. In pre-pandemic circumstances, cumulative…

The purpose of this proposed quantitative, ex post facto, comparative study with a pretest-posttest design was to assess gains in overall Critical Thinking (CT) skills, and particularly in the Hypothetical-deductive Reasoning (HDR) skills, for pre-health college students tested before and after a Critical Analyses in Science course they attended…

Science education researchers and curriculum documents have advocated scientific inquiry for more than six decades; however, inconsistent findings concerning its effects on students' learning outcomes have been revealed in recent analyses of large-scale international assessment data (e.g., the Programme for International Student Assessment…

Observational practice is discussed as a substitute for physical practice for motor learning and adaptation. We systematically reviewed the literature on observational practice in reaching and aiming tasks. Our objectives were to identify (i) performance differences between observational and physical practice; (ii) factors that contribute to…

Preservice teachers' self-regulation skills are key to being role models to their students in gaining this affective skill. The study aims to develop a structural equation model (SEM) that shows the relationship between preservice science teachers' perceived role modeling and self-regulation skills. This study has been conducted using the…
