The design of the study was a survey method. 157 middle school students were participated into study from three different schools in Kayseri in the spring semester of the 2017-2018 academic year. Van Hiele geometry thinking test which was developed by Usiskin and adapted into Turkish by Duatepe (2000) and a circle achievement test that was developed by the researcher were used to collect the data. Pearson The circle achievement test and van Hiele geometry thinking levels were correlated to find their link. Assumptions were met, hence independent groups t-test and ANOVA were performed. The results revealed that Grade 7. Students van Hiele geometric thinking levels were lower than expected levels. A moderate correlation was found between the circle achievement test and the van Hiele geometric thinking test. The results obtained from the van Hiele geometry thinking test showed statistically significant mean difference across schools 1 and 2. Moreover, there is no statistically significant mean difference across schools at the circle achievement test. Boy and girl middle school students’ geometry thinking levels and circle achievement test scores were not statistically significantly different from each other.  \nKeywords: Circle achievement test; gender; middle school; spatial ability; van Hiele, geometric thinking  \n* Specialist, Ministry of National Education, Erzincan, Turkey.

It is a universal language with its’own symbol and shape. Mathematics involves processing, estimating, analysing, problem-solving, and producing by using its language. Mathematics provides individuals with reasoning, creative thinking skills, and the development of aesthetic sense (Ministry of National Education-MoNE, 2009) . All other sciences receive the help of mathematics when they reach a level that can reach numerical correlations. Therefore, mathematics is compulsory in learning all sciences. Basic and social sciences gain the identity of being a science in terms of mathematical expression (Göker, 1997, p. 24-25) .  \nThis universal language and culture transform from civilization to civilization without distinguishing language, religion, race, and country. Mathematics is a science that makes silent reforms (Göker, 1997, p. 22) and an important tool for solving problems in our daily lives. Therefore, mathematics-related objectives are encountered throughout our entire learning life (Baki, 2006, p. 46). Nowadays, we use mathematics in many places, starting from setting up the clock of a to set the time and continuing with the solution of the problems that will require calculation of the four operations at home and work during the day (Umay, 1996) The main purpose in mathematics is not to learn the rules, but to solve the problems of numbers and shapes in daily life (Binbasioglu, 1991) . We can list the practical benefits of mathematics, its effects on people and the characteristics of people who know good mathematics with the followings:  \n􀁸 Provide the right decision and reasoning.  \n􀁸 Learn and apply scientific thinking ways and adopt positive thinking principles.  \n􀁸 Improve various","cbCaigG7yJ0YIuzo","https://ap.wps.com/l/cbCaigG7yJ0YIuzo","pdf",662906,24,"English","# Abstract\n# Introduction\n## Role and universality of mathematics\n## Geometry education and van Hiele levels\n## Importance of linking geometry to daily life","[{\"question\":\"What was the main purpose of the study?\",\"answer\":\"To determine the association between van Hiele geometric thinking levels and circle achievement exam results for 7th grade middle school students.\"},{\"question\":\"How was the data collected?\",\"answer\":\"Using a van Hiele geometry thinking test adapted into Turkish and a circle achievement test developed by the researcher.\"},{\"question\":\"What statistical relationships and differences were found?\",\"answer\":\"A moderate correlation was found between the circle achievement test and the van Hiele geometry thinking test.
