When implementing flipped classroom, it needs several learning strategies and E-learning tools to assist students doing blended learning. By studying the learning materials on the E-learning platform in advance, students may have a certain degree of knowledge, he or she may know the target and the contents of a class before class time. In another aspect, students may also find some problems during the self-learning stage. Therefore, the teacher may leverage problem based learning strategy and then guide students analyzing and solving the problems by themselves. In this research, we provide remedy learning and peer interaction tools during learning stage under flipped classroom. In the end of semester, we collected the relation between the learning progress and learning achievements to judge the study results of students. After analyzing, the conclusion result is that a flipped classroom with blended learning which mixed up outcome based learning and problem based learning raised learning achievement of students.
