ÖzMatematik öğretiminin temel amaçlarından biri, öğrencilerin karşılaştıkları gerçek hayat problemlerini çözebilmeleri; matematiği gerçek hayat ve diğer disiplinlerle ilişkilendirebilmeleridir. Matematik derslerinde gerçek hayat problemlerine yer verilmesinde matematiksel modellemenin rolü büyüktür. Matematiksel modelleme, matematikle doğrudan ilgili olan ya da olmayan durumlar arasındaki ilişkileri matematiksel olarak ifade etme ve bu durumlar içerisinde matematiksel örüntüler oluşturma süreci olarak tanımlanır. Matematik öğretmenlerinin matematiksel modellemeye ilişkin görüşlerini belirlemeyi amaçladığımız bu çalışmada, matematiksel modellemenin öğretim sürecinde hayata geçirilip geçirilmediği nedenleriyle belirlenmeye çalışılmıştır. Araştırmanın katılımcılarını Ankara'da devlet okullarında görev yapmakta olan dokuz ortaöğretim matematik öğretmeni oluşturmaktadır. Öğretmenler ile yapılan yarı yapılandırılmış görüşmelerden elde edilen veriler içerik analizi yapılarak kodlanmış ve modelleme etkinliklerinin matematik öğretiminde kullanılmasına engel olan faktörler "öğretmenin modelleme etkinlikleri konusundaki eksikliği, modelleme etkinliklerine yönelik kaynakların nicel ve nitel anlamda sınırlılığı, öğretim programının yoğunluğu, yükseköğretime geçiş sınavının yapısı, modelleme etkinliklerine yönelik öğrenci motivasyonu, öğrencilerin hazır bulunuşluk düzeyleri" olarak belirlenmiştir.Anahtar Kelimeler: Model, Matematiksel modelleme, Öğretim programı, Öğretmen eğitimi.
AbstractOne of the main goals of teaching mathematics is to help students deal with the problems they encounter in real life and grasp the link between mathematics, life, and other disciplines. Mathematical modeling holds great significance in integrating real life problems in mathematic lessons. Mathematical modeling is defined as the process of expressing the relationships between the situations that are directly related or unrelated to mathematics in mathematical terms and forming mathematical patterns in these situations. This study in which we try to understand math teacher perceptions towards mathematical modeling aims to figure out whether or not mathematical modelling is put into practice along with its reasons. The sample of the study is composed of nine secondary school mathematics teachers who work at different public schools in Ankara. The data gathered via semi-structured interviews with math teachers were coded through content analysis, and the factors that prevent teachers from integrating modeling practices in teaching of mathematics were found to be "teachers' lack of knowledge regarding the mathematical modeling activities, lack of quality resources on mathematical modeling activities, the loaded curriculum, the structure of the Transition to Higher Education Exam, student motivation for modeling activities, students' level of readiness."
The change in technology manifests itself in the restructuring of mathematics teaching and learning processes. Effective use of information and communications technology (ICT) in learning environments has gained importance. The ability to prepare technology-based course materials is currently one of the competencies of teachers. In this study, within the scope of the Erasmus+ project titled 'Math Teachers' Adventure of ICT Integration', mathematics teachers were offered an online course called 'Teaching Mathematics with GeoGebra,' which combines geometry, algebra, graphs, statistics and calculus in a single interface. It is both a dynamic geometry software program and a computer algebra system. The aim of this study is to examine the course materials developed by teachers using GeoGebra and determine the errors in their materials. The technology-pedagogy-content knowledge model was used as the framework for the content analysis. Based on the results, suggestions for both in-service training of teachers and future research were presented.
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.
