Improving Students’ Math Writing Skills and Interest Through Online-Based Flipped Classroom Models

In today's advanced technological era, the online-based flipped classroom learning model can overcome online learning problems while improving students' mathematical writing skills and interest in learning. The study aims to improve students' mathematical writing skills and interest in learning with an online-based flipped classroom learning model. The type of research is classroom action research (PTK) with a postest only one group design. The research subjects were 38 students majoring in mathematics education at Bina Bangsa University for the 2019-2020 academic year in the even semester. There are four stages of PTK which are carried out in several cycles, namely the planning stage, implementing actions, observation, and reflection. From the results of this study, it was concluded that the online-based flipped classroom model is effective in improving students' mathematical writing skills. Furthermore, it is concluded that students' learning experiences after being given learning with an online-based flipped classroom model, the majority of which are classified as high.
