The paper presents findings from a study that examined, through the lens of the Image Having layer of the Pirie-Kieren model, the qualitative characteristics of the images that different children formed when engaging with eight, novel partitive quotient tasks. The Image Having layer is the first point of abstraction within the Pirie-Kieren model.…

Purpose: This paper aims to introduce a novel AI learning progression for upper-elementary students and aligns assessment items across levels of each construct to gather evidence of understanding. It also validates this quantitative measure by examining these items as two subscales for psychometric properties using the Rasch model.…

In the body of knowledge in mathematics education research, fractions are one of the researchers' concerns. The reason is because fractions are very difficult for students to understand. This study explores elementary school students' knowledge and obstacles in dealing with the multiplication of fractions. This study employs descriptive…

At present, environmental issues are of concern to all countries, especially for developing countries, and education on waste sorting is urgent. However, it remains a challenge to improve students' learning achievement and engagement in environmental education. Researchers have pointed out the potential of digital games for promoting students'…

There is an urgent need for more Latinx students to pursue careers in STEM related fields as this has historically been an unserved population in schools. This mixed methods study examined the impact of a summer STEM pipeline program focused on hands-on chemistry concepts for 28 Latinx students in the 5th grade. Findings include statistically…

We propose to assess conceptual knowledge of mathematical notions by having recourse to isomorphic word problems. We assumed that failing to solve isomorphic problems is an indicator of lack of conceptual knowledge. To reach these conclusions, two experiments were conducted among 4th and 5th grade students. In experiment 1, each student had to…

Analogy is a powerful learning mechanism for children to learn novel, abstract concepts from only limited input, yet also requires cognitive supports. My dissertation sought to propose and examine number lines as a mathematical schema of the number system to facilitate both the development of rational number understanding and analogical reasoning.…

A learning format gaining attention that encourages language acquisition in science is the use of dynamic models as instructional tools. This grounded theory investigates the impact of the dynamic food chain model as an alternative lesson for teaching food chains. The researchers examined the impact of a paper-based activity and a dynamic model…

Fractions are highly important. Therefore, it is crucial to understand the developmental trajectory of fraction knowledge and its main predictors and consequences. Our research team has proposed that we have a neurocognitive architecture dedicated to processing nonsymbolic ratios, which serves as a startup tool for fractions: the Ratio Processing…

This study aims to find out the effect of activities and practices on concept education to help carry out activities to teach these concepts more effectively and permanently, and determine student preconceptions about the concepts related to the landforms in the 5th-grade social studies curriculum in the learning subdomain called "People,…

A formative pilot study of a fractions intervention was conducted to address the intervention's potential for improving fifth-grade struggling students' knowledge of fractions, and to identify any logistical or instructional design issues, before scaling up for a randomized control trial. In the first section, we provide details of the formative…

Formative assessment is a teaching method that helps to determine the prior knowledge of students, schedule the course plan accordingly, give it the final shape based on the feedback received from students, and encourage conceptual learning. The aim of this study is to introduce the "annotated student drawings" as one of the common…

The present research explores benefits of using young students' drawings in combination with written responses for gathering information about science concepts. Younger students are still very limited in their verbal expression and less biologically literate than older students. The aim was to determine primary school students' conceptions about…

Humans have been living in an environment since its existence. Human approaches and attitudes towards the environment in which they live have changed over time. It is hoped the negative attitudes of humans towards nature, the environment and environmental problems will change in a positive way, due to increasing levels of awareness occurring…

Understanding of evolution helps solve biological problems in areas that affect our lives. One of the ways of adopting the concept of evolution leads through a conceptual change. We investigated whether inductively prepared educational activities, focused on evolution, have the potential to create conceptual changes in students' conceptual…
