When learning about fractions, teaching usually follows certain topics -- e.g. part of the whole, fraction equivalence, and size comparison. Not yet answered is whether students' conceptual and procedural knowledge of fractions is coherent between those topics. To answer this question, we performed a latent profile analysis of data from N = 1005…

Economic literacy is critical for success in one's career and life. Such literacy has never been more relevant than today due to supply-chain issues causing product shortages, surging inflation, and rising interest rates. Discovery learning through active learning materials discussed in this article were employed with fifth and sixth-grade…

Student's learning and retention of academic content in a meaningful way depends on strengthening their cognitive structures. Once this structure, which provides a framework in which new knowledge will be included, is ascertained, engaging in teaching activities can create an opportunity for learners to have a different learning experience. Word…

Concepts are where the foundation of scientific knowledge and thought structures are laid. Thanks to concepts, distinctions or generalisations about an event or an entity are formed and thought structures are formed in our minds. In this study, it was aimed to determine the associations in the minds of secondary school 6th grade students about the…

Circulatory system is a challenging subject for middle school students to learn and understand conceptual relationships. To address these challenges, this study developed plugged (computational thinking activities using computer) and unplugged (computational thinking activities without using computer) teaching modules that integrated computational…

Circle and disc are fundamental concepts introduced in middle school, forming the basis for many other mathematical ideas. Students often face challenges in comprehending circles, discs, and their basic elements. This research examines the processes of sixth-grade students in constructing circles, discs, and their essential components within a…

This study investigates sixth-grade Turkish students' pattern-generalization approaches among arithmetical generalization, algebraic generalization, and naïve induction. A qualitative case study design was employed. The data was collected from four sixth-grade students through the Pattern Questionnaire (PQ) and individual interviews based on the…

Within the scope of the Law and Justice course curriculum, it is aimed to provide students with knowledge and skills such as the development of law and justice awareness, and the development of legal literacy. This study aims to reveal students' perceptions about the concepts of law and justice in the Law and Justice course curriculum, which is…

Models and modeling are central to both scientific literacy and practices as demonstrated by the Next Generation Science Standards. Through a design-based research framework, we developed a model-based assessment (MBA) and associated rubric as tools for teachers to understand and support students in their conceptualization of the flow of energy…

This research with middle school students from Kentucky (KY) and Nevada (NV) provides a snapshot of students' spatial-scientific understandings as we explored how well students understand lunar-related content, both spatially and scientifically, after receiving instruction with similar curricular Earth-Space content. Utilizing a lens of spatial…

This study is an exploration of how U.S. middle school students interacted with different topics in world history, and how their specific understandings of topics were connected to both sociocultural and instructional contexts. I observed two world history classrooms in a Midwestern Catholic school for 10 months and conducted task-based group…

The aim of this study is to examine the cognitive structures of the secondary school students towards the concept of health. The study was carried out using the descriptive survey model, which is a research approach that intends to describe a past or present situation as it is. The study group of the research was determined by maximum diversity…

Energy is a central concept across the sciences and an important goal of science education is to support all students so that they develop a full understanding of the energy concept. However, given the abstract and complex nature of the energy concept, only a few students develop an understanding so that they can use energy ideas to make sense of…

To improve understanding of identities and inverses, and to provide a stronger foundation for future mathematics, Sandra Miles designed a two-part lesson that makes the relationship between identities and inverses explicit. This article illustrates Miles' teaching of the first part of the lesson, focused on addition and subtraction, and then gives…

Sixth-grade science students at Gauger-Cobbs Middle School in Newark, DE, had misconceptions about how heat energy moves in the hydrosphere through conduction, convection, and radiation. As a result, students struggled to develop and connect ideas that correctly and completely explained heat transfer in the hydrosphere at the end of the lesson…
