The purpose of this study was to study the attitude towards statistic and the students learning achievement through Statistic I of students through the use of a cooperative learning method with STAD. The samples was students in the 2nd semester of 2005 academic year of Rajamangala University of Technology Phra Nakhon. The students of 1 classroom was selected by using simple random sampling method. The design of this study was one group pretest -posttest design. The data statistically analyzed by t -test for independent samples. The results were as follows: 1.The attitude towards statistic of students who learned form use of a cooperative learning wit~ STAD was significantly higher than the students who without learned form use of a cooperative learning with STAD at the 0.05 level. 2.The statistic I achievement of students who learned form use of a cooperative learning with STAD was significantly higher than the students who without learned form use of a cooperative learning with STAD at the 0.05 level.

The purposes of the research were to create and find efficiency validation of computer assisted instruction focused on the practice to record data for report writing for t Ie standard 90/90 and analyze the student learning achievement after using (computer assisted instruction. The I samples were the 20 first year Bachelor of Science in Technical Education st~dents enrolled in Industrial Engineering Rajamangala University of Technology fhra Nakhon North Bangkok Campus. The Researcher experimented by using prete~t and then using the computer assisted instruction focus on the practice to Iprepare specimens in learning next the students did the posttest. After that the resrarcher calculated to find the computer assisted instruction efficiency and analyzed:! the students leaning achievement after studying. The result revealed that the computer assisted Instruction efficiency was efficient for standard 90 / 90. And after studying by using computer assisted instruction tme students learning achievement increased significantly at 0.05.
