The purposes of this study were to (1) Create and find an effective learning package for Increasing learning achievement of school under Khon Kaen primary educational service area office 3, (2) Study the effectiveness index of learning package,(3) Comparison of teacher learning academic achievement before learning and after using the learning packages, (4) Assessing the quality of learning package, (5) Study the teachers' satisfaction towards the use of learning packages. The target group was teachers, under Khon Kaen primary educational service area office 3, Semester 2, academic year 2018, amount of 108 persons using cluster sampling (Cluster Random Sampling), research and development (R & D) is divided into four phases. Phase 1: Study basic information about learning package development, Phase 2, develop learning packages, Phase 3: Use of Learning Package and Phase 4 Evaluation of the use of learning packages. Research instruments use in the study, consisting of (1) 4 learning package sets (2) 80 inter-school and post-test tests as 4 multiple-choice tests with difficulty (p) from 0.40-0.77, classification power (r) from 0.27-0.67 and the reliability of the questionnaire was 0.86 and 40 achievement tests with difficulty (p) from 0.36-0.75, classification power (r) from 0.38-0.78 and the confidence was to 0.89, (3) 30 items learning package quality evaluation form, and (4) 30 vocational certificate students that used instructional package with the reliability of 0.94, statistical analysis data included percentage, average, standard deviation and (t-test). The results of the research showed that 1) Learning package effectiveness was from the test during the whole course (E1) and the effectiveness of the results (E2) after the class will have E1/E2 at the level of 86.38/88.41 was higher than the criteria set 80/80. 2) Learning Package effectiveness index was the overall effectiveness of learning (E.I.) was 0.7678, indicating that teacher knowledge increased to 0.7678 or 76.78 percent. 3) The learning achievement of teachers found that after learning has a higher score, and from the t-test, found that the test scores before studying was ( =36.63) and post-tests cores was ( =70.73) and the development results was 34.10, indicating that overall, teachers with more development differences were statistically significant at the .01 level. 4) Quality of learning packages for Increasing learning achievement of school, the overall average was high level ( =4.54) 5) The satisfaction of teachers towards using learning packages for Increasing learning achievement of school, with the average was highest level ( =4.63)
