Abstract
When confronted with problems such as teaching in large classes, students of differing abilities, distance education and differ expectations for classes, it has become more challenging to satisfy students and maintain quality teaching using traditional teaching. According to previous problems, we propose a teaching model using problem-based learning with situated learning and differentiated instruction. We compose teams of students from various backgrounds to cooperate, team members are assigned to different positions: project manager, user experience engineer, research and development engineer and quality assurance. They have to accomplish a project from real-world problems and develop the product in the following steps: idea generation and screening, concept development, development and launch product. Then we apply differentiated grading and are committed to whether students achieve their learning goals. We use mixed methods research to evaluate our teaching achievements, we compare students’ grade and their feedback from course evaluations, invite experts to classify team projects and have interviews with students to understand their thoughts. We expect that our proposed teaching model can improve recent problems, motivate students and deeper learning, and connect with real world to learn and cooperate together. And Differentiated grading can make student to focus on their learning goals, get a sense of accomplishment from our courses. Keywords: Problem-based learning, Situated learning, Differentiate instruction, Mixed methods research.
