The research aims to investigate the learning progress from applying the practice module for enhancing basic Math as well as the instruction applying CAI along with traditional class method for the course Engineering Mathematics 1. The sampling population included 4-year undergraduate engineering students from 9 majors in the academic year 2003. From the total 300 students who joined Math improvement program during the summer time, the sampling group of 136 students volunteered to participate in the project. The subjects were tested for their basic knowledge score and achievement score. The progress was indicated by the difference between the former score gained before practice with the module and the achievement score gained after such practice. The correlation between the achievement score and basic score would be analyzed afterwards. The t-test was conducted to compare the two means while their relationship was tested by Pearson s Product Moment. The relationship was presented by a profile line. The data was analyzed by SPSS for Windows 12.0 and the results are as follows: 1. Basic Math scores of the students joining the project were significantly higher than the scores gained before participation (p<.001). 2. The average progress of the sampling population being instructed by traditional class method combining with CAI was 14.39 from the total of 40 points, with 0.656 positive relationship with the basic knowledge score (p<.001), revealing that the progress in Engineering Math 1 could be explained by the method of traditional training in connection with additional Computer Assisted Instruction.
