The main purpose of this research is to examine the informal strategies of fifth and sixth grade students while solving inverse proportional word problems. Multiple case study was used in this study. The research was carried out in a public middle school from a southern city of Türkiye. The participants of the research consist of three fifth and…

Mathematical problem-posing and modeling are essential skills in developing students' analytical thinking and problem-solving abilities. This study aims to examine correlation between 9th-grade students' problem-posing and mathematical modeling skills within the learning domain of numbers and algebra. Additionally, it evaluates students'…

The development of proportional reasoning is crucial for higher-level mathematical skills. Various studies have demonstrated that the numerical structures of problems have an impact on the strategies used to solve direct proportional problems. This research was conducted to determine eighth grade students' strategies for solving inverse…

This explanatory case study aims to investigate conceptual changes on the part of gifted and talented students and describe their reflective thinking with regard to problem-solving as part of the problem-based learning (PBL) process. Twenty-two gifted and talented fourth grade primary school students participated in the study. The students were…

The purpose of this mixed-methods sequential explanatory study is two-fold. It is intended first, to determine the effect of problem-based learning (PBL) on problem-solving skills, and second, to reveal student opinions regarding PBL. A quasi-experimental design with a pre-test and post-test control group was preferred in the quantitative…

In this study, an assessment tool was developed to measure the reasoning skills (RS) of preservice science teachers on socio-scientific issues (SSI). As a result of the literature review, the scale was developed based on five dimensions. These dimensions are complexity, questioning, having different perspectives, skeptical approach and the…

In this study, it was aimed to examine the probability problems which were posed based on continuous sample space and discrete sample space. Participants of the study consisted of 48 university students selected by using the convenience sampling method. Eight tasks related to continuous and discrete variables were designed by the researcher. Eight…

With this research, it is aimed to determine the problems faced by classroom teachers who have Syrian immigrant students in their classrooms in Turkey. The research was designed as a single case study, one of the qualitative research methods. Criterion sampling method, one of the purposive sampling methods, was used. The participants of the…

Although there are numerous studies and discussions about the concept of value, it is claimed to lack an objective basis. The concept of value is difficult to define from a single perspective because it relates to many disciplines, especially the social sciences. Philosophy, sociology, psychology, religious sciences, anthropology, and historical…

This study explores gender-based differences in sixth-grade students' potential for mathematical creativity through the interrelated processes of problem solving (PS) and problem posing (PP), grounded in a multidimensional framework of creativity--encompassing fluency, flexibility, and originality. A total of 346 sixth graders from public schools…

The aim of this study is to reveal the meanings that fourth grade students in elementary school attach to the four operation symbols (+, -, x, :) that are abstract, in different representations. The pattern of the study is a case study of qualitative research methods. In the study, the evaluation tool developed by the researchers was applied to…

This study investigates the impact of the problem-based learning (PBL) model on middle school students' environmental literacy and problem-solving skills. A quantitative research study was conducted using a quasi-experimental design for this aim. The sample comprises 114 8th-grade students from a public middle school in Sanliurfa, Turkey. Four…

In this study, it was aimed to determine the level of use of self-regulation strategies by science teachers while problem-solving in their lessons according to the variables of gender, education level, and professional exprience. This study was carried out on a total of 800 volunteer science teachers working under the Ministry of National…

In this cross-national study, we explore the different ways of reasoning-and-proving (RP) presented in three 8th grade textbooks, one from each country: Turkey, Norway, and Slovakia. While the analysis revealed that all three textbooks contain similar numbers of problems involving some form of RP, differences exist in terms of the dominating ways…

Gifted students are individuals who show extraordinary development in at least one area compared to their peers. The common feature of gifted students is their creativity. The gifted students need training to improve their skills. If they do not receive such training, their abilities will fade out over time. Problem posing is one of the activities…
