The aim of this study is to examine the effects of mathematical modeling activities related to STEM approach on mathematical literacy levels and achievements of secondary school students. The study group of the study included 66 eighth grade students who continued their education in a district center of Hatay. The sample group of the study was determined according to the criterion sampling method. "Mathematics Literacy Scale", "Mathematics Literacy Achievement Test" and "Semi-structured interview form about mathematical modeling activities based on STEM approach" were applied as data collection tools. In the study, while mathematical modeling activities based on STEM approach were applied to the experimental group, the control group was taught according to normal mathematics curriculum. As a result of the research, it was found that the mathematics literacy levels and achievements of the students developed positively.
This study was conducted to examine the effect of mathematical modeling activities on mathematical modeling skills of secondary school students in the context of STEM education. The study was designed according to the embedded design, one of the mixed research methods. The study group of the research consists of a total of 66 eighth grade students studying in a public school in the central district of a large province in the south of Turkey in the 2020-2021 academic year. While the criterion sampling method, one of the purposeful sampling methods, was used to determine the quantitative study group of the research, the maximum variation sampling method was used to determine the qualitative study group. On the other hand, in the context of STEM education, mathematical modeling problems, evaluation rubric and semi-structured interview form were used as data collection tools in the research. As a result of the research; It was concluded that mathematical modeling activities in the context of STEM education positively improved the mathematical modeling skills of secondary school students. In addition, it has been concluded that the students who receive education with mathematical modeling activities applied in the context of STEM education gain different interdisciplinary perspectives, experience positive developments in their thinking skills, adapt to group work more easily, and increase their interest in engineering and technology.
