THE BLENDED LEARNING ON C PROGRAMMING FOR GRADE 9 IN DEBSIRIN SCHOOL

Abstract

The purposes of this study were 1) to develop a blended-learning lesson plan on C Programming, 2) to develop web-based instruction (WBI) on C Programming, and 3) to compare learning achievement of the students before and after blended-learning instruction. The samples were  grade 9 students in the academic year 2/2015 from 2 classrooms at Debsirin School, selected by Cluster Random Sampling method. The samples were divided into 2 groups, including 1 classroom with 50 students for the examination of courseware efficiency, and 1 classroom with 50 students for the comparison of learning achievement before and after blended-learning instruction. The research instruments were a blended-learning lesson plan, a WBI on C Programming, a quality evaluation questionnaire, and an achievement test on C Programming with consistency index (IOC) at 0.67-1.00, difficulty value at 0.22-0.80, discrimination value at 0.24 - 0.68 and the reliability coefficient were at 0.89. The data were analyzed by using mean, standard deviation, and t-test for dependent sample The results showed that 1) the blended-learning lesson plan on C Programming was excellent level ( =4.67 and S=0.57), 2) the WBI on C Programming was excellent level  ( =4.79 and S=0.41), 3) the efficiency of the WBI on C Programming was in congruence with the standard at 81.52/84.00, and 4)the post-instruction learning achievement of the students was significantly higher than the pre-instruction learning achievement at .01
