Abstract: Research findings have not yet formally established that Computer-Aided Instruction (CAI) offers a significant improvement over conventional method of teaching. However, in a meta-analysis of 254 comparative Computer-Assisted Instruction studies, Kulik and Kulik found that the students of varying ability levels all displayed significant positive learning gain when using CAI had better examination score, better attitude toward instruction and computers. This covers a wide range of concepts on how to use Microsoft package to solve mathematical problems graphically. Spreadsheet package is used in giving step-by-step solutions to graphical problems with emphasis on Microsoft Excel. The computerised learning activities in this study will supplement conventional instructions of acquiring skills and thus enhances effective students learning.
