The purposes of this research were 1) to develop of web-based learning with augmented reality technology by using self-directed learning model on basic science course to develop learning achievement for grade 8 students of Bang Li Witthaya school 2) to determine the effectiveness of webbased Learning the developed  3) to compared student’s learning achievement result after using the developed 4) to study student’s satisfaction towards using the developed. The sample group in this research were 29 students by using cluster random sampling method, in grade 8 students of Bang Li Witthaya School. Tools used in this research were: 1) web-based learning with augmented reality technology by using self-directed learning model that has been evaluated by experts 2) self-directed learning plan 3) the learning achievement test 4) questionnaires for students’ satisfaction. The research statistics for data analysis are percentage, arithmetic mean, standard deviation and t-test dependent.  Results were as follows: 1) the effectiveness of web-based learning with augmented reality technology by using self-directed learning was 80.23/81.61 which was standard at 80/80 2) the learning achievement was statistically significantly higher than before learning at 0.05 level 3) the student satisfaction towards the developed of web-based learning with augmented reality technology by using self-directed learning model was at high level.
