The purposes of this research were 1) to develop the online lessons using cooperative learning by think-pair-share techniques in technology (computing science) subjects for grade 8 students, 2) to evaluate the quality of the online lessons using cooperative learning by think-pair-share techniques in technology subjects for grade 8 students, 3) to find the effectiveness of the online lessons using cooperative learning by think-pair-share techniques in technology subjects for grade 8 students, 4) to compare the learning achievement of the students before and after learning with online lessons using cooperative learning by think-pair-share techniques in technology subjects for grade 8 students, and 5) to find the satisfaction of students on the online lessons using cooperative learning by think-pair-share techniques in technology subjects for grade 8 students. The sample group used in this research was 40 students of grade 8 students at Rachineeburana School. The purposive sampling technique was used. The instruments used in this research were the online lessons in technology subjects, the assessment form of the content, the assessment form of the techniques and methodology, the learning achievement test, and the assessment form of student satisfaction. The data were analyzed using mean, standard deviation, and dependent t–test.

The research findings showed that 1) the online lessons using cooperative learning by think-pair-share techniques in technology subjects included 3 units; communication technology, computational concepts, and responsible use of information technology, 2) the opinion of the content experts and the opinion of the technique and methodology experts on the online lessons using cooperative learning by think-pair-share techniques in technology subjects were at the highest level, 3) the effectiveness of the online lessons using cooperative learning by think-pair-share techniques in technology subjects was 94.75/83.42 which higher than the criteria 80/80, 4) the students who studied with the online lessons using cooperative learning by think-pair-share techniques in technology subjects had post-test scores higher than pre-test scores at .05 significance level, and 5) the students' satisfaction with the online lessons using cooperative learning by think-pair-share techniques in technology subjects was at the highest level.
