Abstract
Students are facing problem in understanding of what they are learning in mathematics
lesson. There are a lot of students who are suffering from the conceptual change of
mathematics. To conduct the study, a group circulation (discussion ) based on qualitative
method Was employed. This pedagogical system is used to develop students' conception
towards polynomial and rational equations and functions.The main objective of this study
was to identify problems associated with conceptual change of students and assess
conceptual change strategies students use to enhance their mathematics achievement in areas
of polynomial and rational equations and functions .To do these Qualitative research method
was used employing phenomenology research design where the phenomenon was traced
through individual effort and group circulation guided by Apos theory. The study collected
data from 80 students that were selected from two schools from Addis Ababa. Narrative and
thematic data analysis was employed to classify the levels and practical conceptual change
strategies employed by students. From the data analysis the findings from this study include:
Before intervention no student reached the higher level-schema. 34.4% of the students were
found to be at level 3, and similarly 16.9% and 13.8% were found to be at levels 2 and 1
respectively and 35% did not respond. But after intervention 25% of the students reached the
highest level 4, schema. Therefore this study concluded that effective use of conceptual
change strategies help students to develop their understanding and achievement. The teaching
learning process of mathematics needs serious conceptual change strategies. The
mathematics subject needs more strategies or methods in order to understand about it. The
data was analyzed through narration before and after group circulation. The results obtained
were: conceptual change on this title, making students to do problems by their own, good
teaching practices and improving ability. In conclusion, students conceptualized different
ideas of their performance through the level of thinking ( Apos theory).
