THE EFFECTIVENESS OF LEARNING DEVICES OF EARTH AND SPACE PHYSICS ORIENTED INQUIRY MODELS TO IMPROVE CRITICAL THINKING SKILL OF STUDENTS

Physics of earth and space is one of the subject that learn about natural phenomena. Leraning activity thatlearn about nature require students to be able to think logically and critically about a phenomena. Therefore,learning models and learning tools are needed that support lecture activity that allow students to constructknowledge through experiments and gather various information. The fact found that the lectures of earth andspace physics that are used today are still conventional. This does not support the improvement of student’scritical thinking skill. One solution that can be done is to develop lecture devices consisting of worksheetsoriented to inquiry models and earth teaching aids which are implemented in lectures. The aim of thisresearch is to obtain the effectivity value of the devices of earth and space physics lecture to improve thecritical thinking skill of students. Data collection instrument is pretest and posttest before and after use theproduct. Data analysis technique use t-test correlates with product moment. The result of this research is theworksheet of earth and space physics oriented inquiry model is effective improve of student’s critical thinkingskill with the value of the product moment is 60%.
