<![CDATA[This study aims to develop and produce student book and teacher manual book in teaching and learning for the topic of Problem Solving-oriented Linear Equation System of Two Variables with 5E setting. This is a development research on problem solving-oriented learning models with 5E settings. The research utilises supporting learning devices that includes student books, teacher manuals and lesson plans. The process of developing student books and teacher manuals refers to the Plom model of developing procedure. Subject of this study is 36 students of grade X Vocational School 1 Denpasar.
