PENERAPAN PENDEKATAN ILMIAH (SCIENTIFIC APPROACH) DENGAN PROSEDUR UNDO UNTUK MENINGKATKAN HASIL BELAJAR PADA INVERS FUNGSI

Abstract

One of the basic competencies that must be mastered class XI-IPA is "Resolving issues related to the inverse function". Basic competence is also one of the indicators in the national exam, so students of class XI-IPA should really master. However, based on the experience of researchers for teaching mathematics, indicates that any repetition of inverse functions are still many students who score below KKM. From the discussion in MGMPs indicated that student difficulties in determining the inverse function due to step determines inverse functions too abstract. Therefore do classroom action research in an effort to improve student learning outcomes in class XI-IPA-7 (Acceleration) SMAN 2 Brass Odd semesters of the school year 2014 to 2015 on the basis of competence finding the inverse of a function by applying a Scientific Approach (Scientific Approach) with Undo Procedure. Application of Scientific Approach (Scientific Approach) with the Undo procedure is proven to improve student learning outcomes in class XI-IPA-7 (Acceleration) 2 SMAN 2 Brass half of the school year 2015 to 2016 on the basis of competence finding the inverse of a function. This is supported by: (1) the results of the competency test is very high. The average results of the competency test in cycle 1 was 88.44 increase in cycle 2 to 97.50. (2) the group's work was optimal. The average results of the group work in cycle 1 was 96.67 increase in cycle 2 to 100 (3) the results of students' activity quite well. Activity of students in cycle 1 was 83.95 increase in cycle 2 to 96.30. Based on the conclusion, delivered the following suggestions: (1) The Scientific Approach (Scientific Approach) with the Undo procedure can increase the activity of learning and student learning outcomes in basic competency finding the inverse of a function. And (2) To other researchers suggested that trying to conduct action research class that implements the Application of Scientific Approach (Scientific Approach) for the other subjects.
