The Development of Learning Achievement on Plant Propagation by Using the Project Based Approach for Grade 8 Students

Abstract

The objectives of this independent study were 1) to compare learning achievement on Plant Propagation for Grade 8 students using the project based approach between pretest and posttest scores, 2) to compare learning achievement on Plant Propagation for Grade 8 students using the project based approach between post-test scores and criteria at 70%. The sample of this study was Grade 8 students at Nongkipittayakom school, Nongki, Burirum, under the office of Secondary School Area 32. There were 45 students as a sample group. The research instrument consisted of learning achievement test that had the difficulty index between 0.38-0.76, discriminative index between 0.20-0.38; and total reliability at 0.46. The statistics used to analyze the data were percentage, mean, standard deviation, and t-test for one simple.   The research showed that 1) Learning achievement on Plant Propagation using project based approach for Grade 8 students had post-test scores higher than pretest-scores with significant difference at .05 and, 2) learning achievement on Plant Propagation  using project based approach for Grade 8 students had post-test scores higher than the criteria at 70% with significant difference at .05.
