Fractions are perceived as one of the most difficult areas in school mathematics to learn and teach. The most frequently mentioned factors contributing to the complexity are fractions having five interrelated constructs (part-whole, ratio, operator, quotient and measure) and teachers' pedagogical approaches to address these constructs. The present…

Developing textbooks of optimal quality is crucial for enriching the students' learning and understanding. This study examined fraction addition and subtraction problems in the U.S. and South Korean mathematics textbooks according to the types of denominators. In particular, we investigated Everyday Mathematics (EM) and South Korean mathematics…

Teachers' and parents' perceptions of scientific creativity are assumed to be an important environmental factor for scientific creativity, so this research surveyed their perceptions of the behavioral characteristics of scientific creativity and compared their perceptions to those of students. This is achieved with a list of behavioral…

Limited research exists to target algebra instruction for students with intellectual and developmental disabilities (IDD). In this study, researchers compared the use of concrete -- with scaffolds added by researchers -- and virtual algebra tiles -- with inherent scaffolds -- to support the acquisition, fluency, and generalization of linear…

Computational Thinking (CT) and creativity are considered two vital skills for the 21st century that should be incorporated into future curricula around the world. We studied the relationship between these two constructs while focusing on learners' personal characteristics. Two types of creativity were examined: creative thinking and computational…

In this paper we analyse the role of the teacher in a Digital interactive Storytelling in Mathematics (DiST-M) activity. involved in the story as a character (the Guru, a math expert), the teacher acts as a mediator in students' problem-solving process. We analyse how the teacher may orchestrate the mathematical discussions to allow students…

This research was prepared in order to determine the change in students' academic achievement, retention levels and attitudes, and problem solving skill and creative thinking skill as a result of programming teaching with authentic task-based applications. The research was prepared using an experimental design with pretest-posttest control group.…

Teachers adapt their instructional strategies over time based on a variety of contextual constraints. In response to these challenges, teachers often have to make changes to their PBL approaches. While the literature has documented generally positive results of initial PBL implementations, less is known about the degree to which teachers adapt…

This study aims to integrate the local wisdom of the traditional engklek game into problem-solving-based mathematics learning at the elementary school level. The method used in this study is a mixed-method with an explanatory design. The data analysis technique used in this study was random sampling and data collection was carried out by…

The 21st-Century learning has been widely associated with problem-solving skills in a global perspective but not much related to local wisdom, even though local perspectives are also needed in adapting people's daily social lives. The purpose of this research was to analyze the effectiveness of Enculturation-Assimilation-Acculturation (EAA) model…

Teacher professional learning occurs across various contexts. Previous studies on teacher learning and changes in practice have focused on either classroom contexts or learning communities outside of school, but have rarely investigated teacher learning across multiple contexts. Investigating teacher learning across the double contexts of…

Previous work has looked at the relationship between high school preparation and student performance in calculus-based introductory mechanics (physics 1) courses. Here, we extend that work to look at performance in introductory calculus-based electricity and magnetism (physics 2), and we look at the significance of what college math courses have…

We conducted a semester-long ethnographic study of group work in a physics class that implemented the investigative science learning environment approach. Students' conversations were videotaped while they were engaged in group learning activities. Our primary research goal was to better understand what factors made some groups more effective than…

The current study was carried out to determine the problems that preschool children experience during COVID-19 and also what could be done from perspectives of preschool prospective teachers. The working group of the study was made up of 45 projects prepared by 15 preschool prospective teachers attending to the midterm exam of lecture of…

In this article we show how students' productive struggle on a mathematical task can lead to collective mathematical creativity. We use observable (co)actions and interactions from a video record that features three Grade 6 students in a problem-solving session to document the emergence of collective creativity leading to a solution. We discuss…
