Nowadays, scientific approach is not the only approach to teach English using Curriculum 13. English teachers may also use the other approaches; one of them is project-based learning. That is why, it is necessary to conduct a research to develop a model of teaching English using project-based learning to help English teachers teach English to SMA students in Surakarta. The objectives of the research are: (1) to study the quality of the existing model for teaching English in SMA Surakarta; and (2) to develop a model for teaching English using project-based learning which is feasible to develop the students' four English skills. The research method used is Research and Development. Because it is an educational research, it is classified as Educational Research and Development. The results of the research in the first year show that there are still some weaknesses of the existing model for teaching English, so it is necessary to design the prototype for teaching English using projectbased learning. The prototype is tried out until it becomes a feasible model for the teacher to teach English, for the students to study English, and for developing the students' four English skills (listening, reading, speaking, dan writing).
