Development in circle theorems

Abstract

The study investigated the impact and the importance of the use of circle diagrams in the application of circle theorems towards geometry instructions. This study sought to find out what type of instructional approach mathematics teachers use in delivering the concept of circle theorems in mathematics classrooms. Also to find out perceptions students hold towards the learning of circle theorems in geometry. The study also sought to look at the extent diagrams can be used to improve upon learning for application of the concepts of circle theorems in geometry. The study was carried out in Mankessim Senior High School (SHS) in the Central region. The sample consisted of 63 form two students of the selected Senior High School. Business two (2) class was chosen for the study in the school. All the students in the Business class were used with the exception of two students who were absent during the start of the study. Questionnaires, Pre- test and Post- test were administered on mathematics teachers and students in the school. The data were then examined to obtain the attitudes students hold towards the use of circle diagrams in the application questions relating to circle theorems in geometry. The findings from the research questions were analysed which indicated that majority of the students liked the use of diagrams to enable them understand the geometry concept, like in the case of circle theorems. Also, majority of the students felt satisfied when using the circle diagrams in learning the concepts of circle theorems in geometry. The findings from pre-test and the post-test results indicated that the understanding and application of circle theorems using diagrams have improved upon the level of conceptual knowledge of the students in a given mathematical area. The results indicated that students‟ knowledge and understanding and application have improved as a result of the use of circle diagrams.
