Enhancing of Science Learning on Soil and Water Resources Using Web-Based Instruction for 8th Grade Students
Main Article Content
Abstract
The objectives of this research were to 1) develop the web-based instruction (WBI) on soil and water resources for 8th grade students, 2) assess the quality of the WBI by experts, 3) compare the students’ learning achievement before and after learning with the WBI on soil and water resources, and 4) study the students’ satisfaction toward the WBI on soil and water resources. The sample group was one classroom of 8th grade students (n = 31), which was selected by cluster random sampling. The research tools consisted of: 1) the WBI on soil and water resources for 8th grade students, 2) the WBI quality assessment form, 3) the learning achievement test on soils and water resources, and 4) the students’ satisfaction questionnaire toward the WBI. The research
design of one group pretest-posttest design was used in this study. The data were analyzed by using means, standard deviation, and t-test for dependent samples.
The results showed that 1) developed the web-based instruction (WBI) 2 units (1) soil and
(2) water resources, 2) the quality of the WBI was at a very good level, 3) the mean scores of students’ learning achievement of posttest were higher than those of pretest at the statistically
significant .05 level, and 4) the students’ satisfaction toward the WBI was at a very good level.
