The purpose of this research is to examine the effectiveness of teaching mathematics by using flipped classroom. The participants of this study consist of 42 grade-11 students in mathematics class at Demonstration School of Suan Sunandha Rajabhat University, Bangkok, Thailand. This was taken in the second semester, academic year of 2014. The instruments used in this study include video lectures, worksheets and in-class assignments. The researcher found that flipped classroom encouraged students to be able to manage time in classroom more efficiently and improved their achievement in learning Mathematics at the expected criteria 70 percent. Video assisted students to access and understand the contents with sample problems more clearly. Another strategy, in-class assignments, allows students to have more opportunity to communicate with their teacher. Flipped classroom allows students who can’t mark it to some classes be able to catch up to lessons anytime and anywhere. This approach increases opportunities for student engagement which helps students to achieve the course’s learning objectives.
