Effectiveness of Flipped Classroom to Mathematics Learning of Grade 11 Students

ABSTRACT 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. ! Keywords: Flipped classroom, Video Lecture, Achievement 1. Introduction ! Learning circumstances nowadays has changed according to rapidly changing technology. This paradigm shift has resulted in the seeking of new systems and the adjusting and updating of current methods in order to be in accordance with today's ever changing age. Therefore, ideologies, systems, and practices that have been implemented in the past, may be analyzed and reviewed in order to assess the quality and the appropriateness of the results. There is now an important goal for educational institutes to develop and create newer systems to improve learning environment. (Paje,S, 2013) Traditional learning is when the teacher feeds information and experiences to their students and the main focus is at the teacher. This is a teacher-centered method which is different from the flipped learning method where the methodologies, focus, and energy are given to the learners; individualized competency. The knowledge, skill, concentration, and wisdom given to the individual are self-paced and the teacher assigns various types of work via ICT. In addition, this method of learning is taken place outside the school and gives freedom to the learners to have fun with the learning materials. This has inevitably changed the role of teachers. With that being said, tutors and coaches have emerged as the instigators and facilitators in the classroom. They have created enjoyable activities and suitable learning environment for their learners. Through the use of flipped classroom, a holistic or a mastery of learning is creates. This is also a highly effective method to teach students and kids. This creates cooperation, built confidence, given opportunities for critiques among students. This mastery of learning method shown in the study is to improve the acquisition of knowledge and concepts of 80% of the students whereas if taught with traditional learning, only 20% would have understood the material. (Panich,V, 2013) Characteristics of Mastery Learning according to Tisna Khammani (2010) is that
