This research investigates the educational effects of online-integrated science program for economically disadvantaged 6th grade students. There were two classes with different learning methods: one with only the online-mentor and the other with both online and onsite mentors. The students received self-esteem scale and academic self-efficacy test at the very first and last class of the program. As a result, students showed positive alteration of self-esteem and academic self-efficacy after the program, meaning this program is effective at developing student's self-esteem and academic self-efficacy. This proposes that more education programs should be provided in order to raise underprivileged students with high potential into outstanding individuals.
