The purpose of this study is to develop a concept model of integrating off-campus internships and capstone courses through mLearning technologies. There are five steps of this concept model. The first step is to develop the teaching objectives and digital teaching material for the integration of off-campus internships and capstone course in the technological universities. The second one is to introduce the business mentors to join the teaching plan for integrating of off-campus internships and capstone course. The third one is to design a pretest-posttest control group experimental design. The experiment group uses our course design and based the mlearning technologies to achieve the teaching strategy. Then, the study will compare the result of two groups in pretest and posttest. It will take the pretest scores of employability skills for experiment group as covariates. Finally, it will use ANCOVA analysis to understand whether students can effectively enhance the employability skills through mLearning teaching strategies during off-campus internship and capstone courses.
