Eğitim alanında yaşanan gelişmeler öğretim programlarının zaman zaman değiştirilmesini gerekli kılmaktadır. Matematiğe değer veren, matematiksel düşünebilen, matematik dilini kullanabilen ve iyi problem çözebilen bireyler yetiştirmek amacıyla İlköğretim Matematik programı 2005 yılında yenilenmiştir. Yenileme sırasında içeriğe yeni bazı konu ve kavramlar eklenmiştir. Bu araştırmanın amacı, ilköğretim (6-8. sınıflar) matematik dersi öğretim programına giren yeni konuların programa alınmasının uygunluğu ve bu konulardaki pedagojik alan bilgisi yeterlilikleri hakkında matematik öğretmenlerinin görüşlerini belirlemektir. Araştırmada betimsel tarama modelinden yararlanılmıştır. Araştırmanın çalışma grubunu Tekirdağ ili Merkez ilçesindeki ilköğretim okullarında görev yapan 27 matematik öğretmeni oluşturmaktadır. Verilerin toplanması aşamasında araştırmacılar tarafından hazırlanan yeni konulara ilişkin 9 açık uçlu ve yeterliliklere ilişkin 17 kapalı uçlu sorudan oluşan anket formu kullanılmıştır. Toplanan verilerin analizinde yüzde ve frekans değerlerinden yararlanılmıştır. Araştırmanın sonuçlarına göre, öğretmenlerin genellikle yeni konular hakkında olumlu görüş bildirdiği ve bu konulara ilişkin kendilerini yeterli buldukları tespit edilmiştir. Elde edilen bulgulara dayalı olarak matematik dersi öğretim programına giren yeni konuların öğretimine yönelik öneriler geliştirilmiştir

Purpose: There are mathematical behaviors in all levels from the preschool education to higher education programs. These behaviors are in mathematics curriculum as objectives. Elementary Mathematics (6-8th grades) curriculum was developed in 2005 at last and applied gradually from the 6th grade in 2006-2007 academic year. Thematic approach was considered in regulating context in new mathematics curriculum and determined learning domains and sub learning domains. Some subjects were taken out and some new subjects were added in developing program studies. Patterns and relations in integers, translation, tessellations, structural drawings, transformation geometry, fractals, geometric movements, histogram,kindsofprobability,standarddeviation,combination,perspective drawings, intersections of objects, polyhedral objects, symmetries of geometric objects are some new subjects in mathematics (6-8th grades) curriculum. Patterns and relations in integers and special number patterns are in Patterns and Relations in Algebra learning domain, translation, reflection, rotation, geometric movements and symmetries of geometric objects, tessellations and fractal, structural drawings, intersections of objects and polyhedral objects are in Geometry learning domain, histogram, kinds of probability, standard deviation, combination are in Probability and Statistics learning domain. The purpose of this study was to determine mathematics teachers' opinions and qualifications about new sub learning domains in elementary mathematics (6-8th grades) curriculum. The descriptive survey method was used in the study. The work group of the study consists of 27 mathematics teachers from primary schools in Tekirdağ. Datawerecollectedbyaquestionnairewhichhasbeendevelopedbythe researchers. The questionnaire has 9 open-ended and 17 close-ended questions. Open-ended questions were used to determine mathematics teachers' views about new sub learning domains were suitable or not for these grades. Close-ended questions were used to determine mathematics teachers' views about their qualifications about new sub learning domains. Given that the mathematics teachers were asked to explain whether they were qualified about new sub learning domains or not, four choices were offered to the teachers: ,Completely qualified', ,Qualified', ,Partially qualified' and ,None qualified'. Frequencies and percentages were used to analyze data. Results: This study has shown that mathematics teachers have generally positive opinions about new sub learning domains in elementary mathematics (6-8thgrades) curriculum. But some teachers thought standard deviation in Measures of Central Tendency sub learning domain and perspective drawings in Projection sub learning domain were difficult for these grades. According to the results of the study, mathematics teachers thought that they were qualified for these new sub learning domains, generally. But some teachers thought they were partially qualified or none qualified for structural drawings, polyhedral objects, perspective drawings, standard deviation, special number patterns, fractal etc. Discussion: The results of this study indicate that new sub learning domains in elementarymathematicscurriculumaregenerallyappropriateforstudents according to mathematics teachers. However, there are some topics which few teachers have negative opinions by indicating reasons why they have these opinions, while majority of teachers have positive opinions about. For example; the difference between histogram and bar graph has not yet understood by some mathematicsteachers.Anotherexampleisthatthetopicsofpatternsand tessellations sub learning domain are found unnecessary by some mathematics teachers. Generally, it is has seen that teachers who have more than twenty-year experience have negative opinions about new curriculum. As a reason for this, it can be claimed that these teachers have difficulty to adapt to a new understanding of the system because oftraining for many years according to traditional understanding of education. Another difficulty can be using tools and technologies, because of the new topics in the curriculum require visualization.The majority of the teachers feel themselves "completely qualified" or "qualified", while a small portion of the self feels "partially qualified" that can be identified as shown by the results of the research. However, it does not change the fact that the study group of teachers that constituted this study they find themselves none qualified on topics such as structure drawings, polyhedral objects, perspective drawings, standard deviation calculations, special number patterns, and fractals.Conclusion: This study has shown that teachers generally have positive opinions about new sub learning domains in elementary mathematics (6-8th grades) curriculum and they think that they have qualified pedagogical content knowledge to teach these domains. The Ministry of Education and researchers can be offered as follows: The Ministry of Education should organize in-service training about understandingandteachingnewsublearningdomainsinmathematics curriculum. In addition, mathematics course hours can be increased and the mathematics classes which include all mathematics materials can be arranged. Thecontents of courses in education faculties should be overviewed by means of teaching new subjects. It should be determined mathematics teachers' opinions qualifications about new other subjects in other grades' mathematicscurriculum.
