Brain-based learning: Using 4MAT model for teaching transformations in geometry
(2020-12-11) Aliustaoğlu F.; Tuna A.
Many models that take into account the learning styles have been developed with the formation of modern educational approaches. 4MAT model is a natural learning process moving sequentially through the learning cycle. According to the 4MAT model there are four learning styles and each student can learn more comfortable with their own learning styles. In consideration of neurological studies, also, the dominant hemisphere used by individuals in the information processing process is important in the 4MAT model. This chapter presents a lesson plan based on the 4MAT model as well as the results regarding the application of this lesson plan in a middle school located in the northern part of Turkey. The lesson plan was prepared by examining the books titled "4MAT 4 algebra: The system of mathematics" and "4 MAT 4 geometry teacher book" and receiving expert opinions.
Examining the pedagogical content knowledge of prospective mathematics teachers on the subject of limits
(2021-01-01) Aliustaoğlu F.; Tuna A.
This research aims to investigate the pedagogical content knowledge (PCK) of prospective mathematics teachers on the subject of limits, based on the two components of PCK: the knowledge of student understanding and the knowledge of instructional strategies. The research sample comprises 33 fourth-year prospective Mathematics teachers (known hereafter as Mathematics Teacher Candidates or MTCs). As a data collection, a tool PCK test was used and the PCK test contains seven questions, including questions related to the misconceptions of students about limits. The MTCs were asked to identify inaccurate answers to each question, to state the causes of the mistakes and to design an instructional process to eliminate these mistakes. A descriptive analysis technique was used to analyze the data. Based on the ‘knowledge of student understanding’ component, it was observed that the MTCs could not find the reasons underlying the mistakes, even though they could determine the student's mistakes. On the other hand, based on the ‘knowledge of instructional strategies’ component, it was seen that most of the MTCs did not fully express their process in correcting the students' mistakes or only gave general answers. It was seen that there were deficiencies in both knowledge components.
Misconceptions of sixth grade secondary school students on fractions
(2018-06-01) Aliustaoğlu F.; Tuna A.; Biber A.Ç.
The purpose of this study is to determine the misconceptions of 6th-grade secondary school students in terms of part-whole relation in fractions, representation of fractions on the number line, comparison of fractions and operations in fractions. The sample of this study is composed of 104 students who are being educated in 6th-grade of five secondary schools in 2017-2018 teaching year in a province which takes place in the north part of Turkey. Fractional information test, which consists of 5 open-ended questions developed by researchers, was used as data collection tool. The data of the study were analyzed using the content analysis method and in this method frequency/percentage tables were used. By examining the explanations that the students have made, the incorrect answers are divided into categories, and the misconceptions in each question are presented separately. As a result of the study, it has been seen that students have misconceptions in terms of parts-whole relation in fractions, representation of fractions on the number line, comparison of fractions and operations in fractions.
