The aim of this research is to find the problems of advanced writing skills of upper elementary school students, and provide solutions. The research method used is a literature review. Based on the research results, it can be concluded that there are two factors that cause students' difficulties in writing at a high level, namely internal factors and external factors. Internal factors include students' weak motor skills, weak visual memory, low students' interest and motivation to learn, and finally students' study habits in class and at home. Meanwhile, external factors include lack of attention from parents towards students, an atmosphere at home that is less supportive, environmental conditions and finally the influence of social media. The lack of writing skills in elementary school students may also be caused by the less than optimal use of innovative learning methods. One way to optimize the writing learning process and increase students' writing motivation is to increase students' interest in writing through interesting learning models and learning media.

The problem-based education model begins with posing a problem or posing a problem, focusing on disciplinary relationships, investigation, group collaboration, as well as creating work, demonstrating and solving the given case. This problem-based education is student-centered, where teachers only share a little data and students who want to be more active in solving problems. This problem-based education uses real (authentic) problems that are unstructured and open-ended as a context for students to improve their problem-solving and critical thinking skills, and at the same time build new knowledge. In contrast to conventional education where real problems are used as the implementation of concepts, problem-based education makes real problems a factor in students' learning process before they understand formal concepts.
