Abstract: Abstract This study determined the effects of an Intelligent Tutor System (ITS) on students’ achievement in computer graphics in universities in Enugu state Nigeria. The study adopted a quasi-experimental design. The population of the study is 171 final year computer education students in the four universities in the area that offer computer education in the 2022/2023 academic session. 130 computer education students from two intact classes were used as sample for the sample study. The instrument that was used for data collection was the Computer Graphics Achievement Test (CGAT). Kuder Richardson formula 20(K-R 20) was used to determine the reliability of CGAT, which yielded a reliability index of 0.92. The data collected were analysed using mean, standard deviation and analysis of covariance (ANCOVA). The hypotheses were tested at 0.05 level of significance. The result of the study shows that students who were taught using ITS had higher mean achievement scores compared to those taught using the conventional lecture method. There was also a significant difference in the mean achievement and interest scores of students based on method of instruction used in teaching computer graphics. The male students taught computer graphics using ITS had a slightly higher mean and interest scores when compared to their female counterparts. However, there was no significant difference in the mean achievement scores of the students based on gender. It was therefore recommended that ITS be included in the computer graphics programme in universities to foster effective utilization in teaching considering its benefits.
