Abstract:
This study aimed on assessing the influence of self-efficacy belief on mathematics academic
performance between experimental and control group of students in case of Nafyad No.1
Secondary School at Adama town, and identifying the major effects of self-efficacy belief
difference between experimental and control group performance on mathematics achievement.
The methodology used for the study was quasi experiment while participants were purposively
selected for experimental and control groups. The participant of the study were 110 students out
of which, 55 students for experimental group came from grade 10-A while the 55 students of the
control group were from grade 10-B. For this research achievement, two Nafyad High School
principals and three mathematics teachers were involved. After groups were selected the first
semester mathematics mid-test of students was taken as pretest. Then, the treatment was given
which was prepared to enhance the thinking of self-efficacy belief of the experimental group. The
treatment substances were given through training for four weeks. The collected data was
interred in to SPSS with the value of pretest and post test data. The major findings of the
research questions were approved by mean, t-testes, standard deviation and P value obtained
from statistical package of social science. The collected data were analyzed and explained both
quantitatively and qualitatively so as to reach the findings. The major findings obtained from
pretest and post test score were that there were differences before and after the treatment
between experimental and control groups. Secondly, self-efficacy belief differences were also
seen between experimental and control group. The conclusions were the enhanced self-efficacy
belief brought change on mathematics achievement score. The treatment generally changed the
thinking of self-efficacy belief of students to enhance self-belief towards mathematics. It was
evident that the treatments / training given for the experimental groups have caused major
changes on students.
