Abstract: This research aims to develop instructional model problem-based mechanics with multi representation approach (the instructional model of Orientation IPA) to practice students’ critical thinking skill. The used method is research and development referring to Borg & Gall. This development research includes three stages, namely preliminary study stage, the development of model design and trials stage, and model evaluation stage. The focus of this research is in preliminary study and model design development stages resulting the instructional model of Orientation IPA. The expert validation is conducted by three experts and eight teachers of model users. The trial stage is conducted to students of 10th grade of Science Mathematics department of three classes. The sample determination uses Simple Random Sampling technique. The data analysis uses quantitative descriptive technique. The research results show that the instructional model of Orientation IPA meets the validation, practice and effectiveness requirements.

Keywords: critical thinking skill, instructional model of Orientation IPA, multi representation .

I. INTRODUCTION

The educational goals emphasize on knowledge acquisition and must describe the result study until to the high level of thinking, even to the ability to solve problems. In line with this, Gagne (1985) has opinion that the study condition has to be directed to problem solving which is the highest capability in thinking skill. The learning must be directed not only to get understanding achievement but also to improve the critical thinking skill. The development of critical thinking is considered as one of the most important goals from educational knowledge for more than one century (Forawi, 2012). The definitions of critical thinking very vary from the simple one to the complex one. Ennis (1991) defines the critical thinking as reflective and reasonable thinking focusing on deciding what have to do.
