@article{2014,title={INVESTIGATION OF PROSPECTIVE TEACHERS’ CONCEPTUAL AND PROCEDURAL KNOWLEDGE OF TYPES OF EVENTS},abstractNode={Understanding mathematics or learning mathematics with understanding has an important role for students to gain problem solving skills and use mathematical knowledge in their daily lives. Therefore it is necessary to learn mathematics with understanding for doing mathematics. One of the subjects that there have been difficulties for conceptual understanding is ‘Probability’. Probability develops the ability of independent creative thinking, one of the most important purposes of mathematics, and it also develops the ability of probabilistic thinking. Development of students’ probabilistic thinking and dealing with the difficulties of probability teaching depends on teachers’ subject matter knowledge of probability. So, teachers should know the conceptual and procedural aspects of probability and also the advantages of probabilistic thinking. In this respect the purpose of this study was to investigate prospective teachers’ conceptual and procedural knowledge of types of events. A survey model, one of the quantitative research models, was used in this study. The study group consisted of junior and senior level prospective teachers enrolled to department of elementary mathematics education at a government university located in western Turkey. The data were collected by “Conceptual Knowledge Test” (CKT) and “Procedural Knowledge Test” (PKT) and were analyzed by the aid of a rubric developed by the researcher. The working group was of 100 prospective teachers. The findings revealed that the prospective teachers’ subject matter knowledge was generally lacking in conceptual depth and they had inadequate acquisition about types of events. According to the findings, prospective teachers were also inadequate to give real life examples of types of events. Besides, prospective teachers were inadequate in calculations for types of events. In accordance with the findings of the study, some suggestions were made for developing conceptual and procedural knowledge of probability effectively at undergraduate level.},author={Ayla ATA-- Kürşat YENİLMEZ},year={2014},journal={The Journal of Academic Social Science Studies}}
