The sample consisted for grade 7 students in Noppitam Wittaya School year 2017 by the cluster random sampling 2 classes overall 70 students. The research instruments included a WBI for review on integer system, a quality assessment form, a learning achievement test (with p = 0.35-0.68, r = 0.24-0.59, and KR-20 = 0.88). The data were analyzed by using mean ( ), standard deviation (S) and t-test for dependent samples

    The result showed that the quality of WBI for review on standard of network connectivity were at a high level ( = 4.58, S = 0.50) in the aspect of the lesson content and also the media production ( = 4.33, S = 0.61) with the efficiency of 81.11/82.67. The results of learning achievement tests showed that the post-test scores ( = 24.20, S = 3.44) of the students were significantly higher than the pre-test scores ( = 13.77, S = 4.04)
