The purpose of the study was to examine the effects of using mathematical games on 4th grade students" attitudes towards mathematics course and their visual metaphoric perceptions. The study was conducted with 101 students in a public school in Istanbul. Mixed method research design was used in the study. The attitude scale prepared by Baykul (1990) was applied as pre-test and post-test to the students in the experimental and control groups. At the same time, the metaphoric perception form which was formed to understand the visual metaphoric perceptions of the students was applied as pre-test and post-test to the experimental group students. According to the findings, it was seen that the mathematical games which were applied did not make a significant difference on students" attitudes. However, significant differences were found in visual metaphors created by students. As a result of the detailed analysis of the elements in visual metaphors, it was observed that the use of mathematical games generally affected the metaphorical perceptions of students about mathematics positively.
Due to the nature of physics, problem-solving strategies are applied in some cases to teach many subjects. Problem-solving is a process that individuals use, not only in physics classes but also in every stage of life. An algorithm is a pathway to solving a problem or achieving a specific purpose. The purpose of this study is to identify how pre-service science teachers express the algorithms they utilize in the process of solving physics problems. The research design of the study was determined as survey design which is one of the quantitative research methods. The study was carried out with the number of 34 pre-service science teachers consisting of 1st and 3rd-year university students who took General Physics I and General Physics Lab I courses in the undergraduate program in science education at a state university. They were given three problems regarding classical mechanics and then asked to solve these problems and schematize their algorithms by using flowcharts. The International System of Units (SI) was used throughout the research. An evaluation was made by comparing the 3 algorithms of the solution, whose reliability and validity was ensured, and which was previously created with the help of 3 experts. In the study, descriptive survey model was used. Frequency tables were frequently used in the analysis of the data with the intent to present the study in the best way by doing an in-depth analysis. In the findings of the research, it was observed that pre-service science teachers had problems in expressing their algorithms and some of them could not express these algorithms at all. It was also observed that pre-service science teachers had difficulty describing the solutions they created while setting up the problem. However, it was observed that preservice science teachers who could illustrate their algorithms well were usually the ones who solved the problems correctly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
