<![CDATA[Abstract: During this period, learning process is still conventional. Teachers still dominate learning process, it makes classroom atmosphere less active. Understanding the concept of a material also decreases. One way to overcome the problem is applying Inquiry learning strategy. This is a descriptive qualitative research by describing mathematics learning process using inquiry learning strategy and it is completed by Students’ worksheets (LKS). This research is conducted at State Senior High School (SMA) 1 Kauman Tulungagung. Observation results in this study consist of teachers and students’ observations. Based on teachers’ observation, the value is 35 and the percentage is 87.5%, so it is categorized into good teacher. Meanwhile, based on students’ activities, the value is 33 the percentage up to 82.5%, so it belongs to active students. The average of learning outcome is 89,61 with minimum completion criteria (KKM) value is 75 for mathematics, and the percentage of learning completeness up to 88,37%. So, it can be concluded that learning outcome with the implementation of inquiry learning strategy has good completeness score. It is based on 43 students’ responses with average value up to 51,04%. So, it is categorized into positive response because students respond well to the implementation of inquiry learning strategy. The results of this study can be used as consideration for teachers in choosing the right strategy for learning, so students can understand the material well.Keywords: Students’ Worksheet, Mathematics Logic, Inquiry Strategy.]]>
