The purpose of the present study was to study the effect of Abacus Mental Arithmetic Program on self-confidence of students in Mathematics. The main objectives were to study the effectiveness of Abacus Mental Arithmetic Program on developing self-confidence in solving mathematical problems and to study the significant difference in the self-confidence scores of boys and girls of experimental group. The sample of the present study consisted of 52 students falling in the age group of 10–12 years and studying in the C.B.S.E affiliated public schools of Ambala City. Out of 52 students, 26 students (12 girls and 14 boys) were in control group and 26 students (11 girls and 15 boys) were in experimental group. The tool used for data collection was Self-Confidence Scale in Mathematics developed and standardized by the investigator herself. On the basis of the analysis of data, it was found that there exists significant difference between the means of post-test scores of self-confidence for control and experimental group. Thus, it was concluded that the Abacus Mental Arithmetic Program helps in developing self-confidence of students in Mathematics. No significant difference was found between the means of post-test scores of girls and boys of experimental group with regard to self-confidence. Thus it was concluded that both girls and boys of experimental group were having the same level of self-confidence after getting treatment.
