Comparision of secondary school mathematics curriculums: 2009-2013-2017-2018

The aim of this research is to reveal the similarities and differences of the secondary school mathematics curricula restored and updated in 2009, 2013, 2017 and 2018 through comparison of their visions, approaches, philosophies, objectives, abilities/skills, values, learning domains and sub domains, learning outcomes and course times. In the study, the criterion sampling method, which is purposeful sampling of the non-random sampling methods, was used in order to represent the population correctly. The criterion was based on 2009, 2013, 2017 and 2018 mathematics secondary school curriculum booklets published by The Head Council of Education and Morality. Document analysis method was used as data collection method. The data were analyzed using content analysis method. As a result of the data analysis, it was determined that a separate section for the vision and philosophy of the program was found only in the 2009 secondary school mathematics curriculum. In terms of philosophy, the curricula were found to have differentiated. In terms of general objectives, 2009, 2013 and 2017 secondary school mathematics curricula were similar, but the objectives were handled differently in the 2018 curriculum. It was seen that the most skills existed in the curriculum of 2009, that the basic skills in the curricula of 2009 and 2013 were mostly similar and that skills were simplified and the most basic ones were included in the curricula of 2017 and 2018. It was also determined that the concept of values was mentioned for the first time in the 2017 and 2018 curricula. The competency section was included in the 2018 curriculum for the first time. In terms of learning domains, it was found that each had 5 learning domains but with some differences in their names. It was found that while the number of learning outcomes gradually decreased, the course hours increased and the four curricula had an understanding of both process and result oriented evaluation.
