Abstract:
The ability to communicate is an essential ability of every human being. The importance of communication is also indispensable in the learning process. In mathematical learning, the ability of mathematical communication is very necessary to continue to be developed. The purpose of this research is to produce a valid and practical guided inquiry based mathematical instructional material for the learning of class X SMK students and to know the potential effect of instructional mathematical instructional materials based on guided inquiry for learning of class X vocational students. The research method used in this research is Design Research Type Development Studies. Research is done in two stages of preparation phase (Preliminary) and formative evaluation stage. Formative evaluation stage includes self-evaluation, prototyping (expert review and one-to-one (low resistance to revision), and small group), as well as field test (high resistance to revision). The result of this research is the result of instructional material in the form of Student Worksheet (SW) which valid and practical. Then based on the process of development and analysis of students 'work in SW, the prototype of teaching materials in the form of SW based on guided inquiry model has a potential effect on students' mathematical communication ability. |
