Investigation of Pre-Service Teachers’ Statistical Literacy Levels
(2024) Soylu, Yasin; Uras, Muhammed Celal; Şata, Mehmet
Statistical literacy is one of the most important actors in the information age. There has been an increase in the importance of education. Therefore, teachers' mastery of statistical concepts is necessary for quality education. The present study aims to examine the statistical literacy levels of pre-service elementary mathematics teachers. The study is a quantitative research with ex post facto design. The sample consists of 530 pre-service teachers in two universities. \"Statistical Literacy Scale\" was used for data collection. For the validity analysis of the scale, a first level confirmatory factor analysis was carried out and the Cronbach alpha coefficient was calculated for reliability. The data were analyzed using independent samples t-test and one-way ANOVA. The statistical literacy levels of pre-service teachers increase with the statistics and probability courses they take during their undergraduate education. It was also concluded that there was a significant difference between the students who took the courses and those who did not. It is recommended to conduct new studies for curriculum development and educational policies by revealing the factors affecting the development of statistical literacy.
Mathematical Literacy, Thinking, and Teacher Self-Efficacy: A Latent Profile Analysis of Preservice Teachers' Competencies
(Izzet Kara, 2025) Uras, Muhammed Celal; Sata, Mehmet; Soylu, Yasin
Professional competence is an important factor in determining the quality of teachers' education. A limited number of studies examine preservice teachers' professional competencies from a person-centered approach. The current study aims to identify latent profiles of preservice teachers' professional competencies. Data were collected from 545 preservice elementary mathematics teachers. The results showed significant relationships between self-efficacy in mathematical literacy, mathematical thinking, and teachers' self-efficacy in mathematical language. The findings revealed that preservice teachers were classified with three different profiles in professional competencies: low, medium, and high. The findings may help target preservice teachers in the risk group of professional competencies and develop programs that will enable them to develop these competencies.
Mistakes and Misconceptions of Elementary School Students About the Concept of 'variable
(Elsevier Science Bv, 2011) Sahin, Omer; Soylu, Yasin
Since the concept of 'variable' requires abstract thinking ( epistemological) and because of the difficulties in teaching this concept ( pedagogical) and approaches of the students towards the concept of 'variable' ( psychological), misconceptions and mistakes occur in teaching this concept. The purpose of this study is to detect the mistakes and misconceptions of the students about the concept of 'variable' along with the reasons for these mistakes and misconceptions and to classify these mistakes and misconceptions. In this regard, the sample of the study is composed of 50 seventh-grade students from Gazi Elementary School which is located in A city center. A test, which is composed of 8 open-ended questions, has been applied in the research in order to collect data. This test has been presented to the students in order to determine the mistakes and misconceptions of the students about the concept of 'variable'. Upon the analysis of the data obtained from the test, the mistakes and misconceptions of the students about the concept of 'variable' have been detected, and these mistakes and misconceptions have been classified in certain categories
Perception Levels of the Students, Who Have Qualified for University Admission, in Mathematical Concepts
(Elsevier Science Bv, 2011) Dundar, Sefa; Ahin, Omer; Soylu, Yasin
This study aims to determine the forms of perception of the students, who have just qualified for university admission, about the mathematical concepts that they gained during elementary education and secondary education process and to determine their level of readiness about general mathematics lesson. In this regard, the sample of the study is composed of 250 first-year students who study at the Department of Science Teaching and the Department of Mathematics Teaching at Kazim Karabekir Faculty of Education, Department of Elementary Education at Ataturk University. A test, which is composed of 8 open-ended questions on the definitions and applications of the concepts, has been applied in order to collect data in the research. According to the obtained results, it is observed that the students do not have much difficulty in the definitions of the concepts whereas they have difficulty in the applications and meanings of these concepts.
