The concept of fractions given in learning is the concept of part of whole and part of unit. The development of student's concepts of fractions can be built through fraction schemes. A partitive fraction scheme is a scheme that estimates the size of the fraction in the form of non-units to the whole that is not partitioned. The concept of…

This study aimed to explore Colombian fifth-graders views about people, events, and situations involved in their gratitude experiences. The sample consisted of 120 fifth-grade children from three mixed-gender schools (one public, two private) in Bogotá, Colombia. The study used a child-centered methodology that involved a novel combination of…

The study aims to reveal students' mental models and perceptions regarding the concept of the celestial bodies, for instance, earth, sun, and moon. This research study was conducted as a case study focusing on qualitative data. This study also has used a sample formed of 5th-grade students, in the 2018-2019 academic year; the target sample is…

"Location and Transformation" skills are critical tools for navigating the world and establishing foundational steps for geometric reasoning associated with co-ordinate grids and the Cartesian plane. The contextual nature of using local landmarks to understand students' mental representation of large-scale space has the potential to…

Mathematics education highlights the importance of helping students understand mathematical content and the ability to think critically about mathematics. Mathematical practice standards outline expectations for engaging students in meaningful mathematics activities to encourage a deep understanding of mathematical concepts and content. For some…

Cognitive model [CM] is the description of individual's problem-solving method on selected tasks at a precise level to make meaningful inference on his/her strengths and weaknesses. CM serves as a foundation in developing a cognitive diagnostic assessment [CDA] that links the interpretation of test score to the attributes. This study employed the…

This study examined preservice teachers' instruction of goals in specific learning domains in physical education class and students' interpretation of these goals. Four preservice physical education teachers (all male) from a large urban university taught two lessons to eight sixth-grade students at an urban K-6 elementary school. The theory of…

The purpose of this study is to determine the mental models of primary school students about the concept of environment. The research group consisted of 400 students, 219 girls and 181 boys, enrolling to the 3rd and 4th grade in a primary school located in Istanbul. The students were asked to draw the environment and explain the items they draw.…

A solid understanding of fractions is the cornerstone for acquiring proficiency with rational numbers and paves the way for learning advanced mathematical concepts, such as algebra. Fraction difficulties limit not only students' educational and vocational opportunities but also their ability to solve everyday problems. Students who exit 6th grade…

Word problem solving skills include complex skills. Teaching word problem solving skills to students with disabilities is more difficult compared to their peers with typical development. Therefore, effective interventions need to be determined in order to teach these skills to students with disabilities. The purpose of this study is to analyze the…

The concept of angles is important for future geometric knowledge (Arslan et al., 2016; Moore, 2013; Yigit, 2014). However, although Piaget (1948) suggests angles lead to the discovery of lines, angles are typically taught later in schools, after points, lines, and planes (Charles, 2011). Therefore, the way in which angles are taught can affect…

Despite significant research exploring students' quantitative reasoning, few studies have explored the semiotic processes that mediate its development. In this report, we present a case study to show how one student constructed a semiotic chain for a quantity as he worked with a mathematical task. Importantly, we connect frameworks for…

Research related to the teaching and learning of the lunar phases reveals a low level of understanding of this astronomical phenomenon by most students of all educational levels. Therefore, there is a need to develop didactic materials to promote adequate comprehension of this phenomenon and which have been tried out in the classroom. Presented…

Instruction targeting the underlying math problem structure is identified as an evidence-based practice for students with a specific learning disability (SLD). Furthermore, schema-based instruction is identified as a potentially evidence-based practice for students with a SLD. This study extended prior work by (a) using a teacher as the…

Mind maps that contain visual and verbal elements can be thought of as an effective graphical tool that can be used to reveal the existing knowledge, opinions and perceptions of individuals about a concept through mental association. In this study, the aim was to determine the mental models of middle school students related to science by using…
