Abstract

The research is aims to determine the effect of feedback on students’ mistake in completing the algebra arithmetic operation. The effect can be seen by the average difference in students’ mistake in completing the algebra arithmetic operation between the given feedback and are not given feedback. The population was all of the second grade students at SMP Negeri 1 Adiluwih in the academic year 2015- 2016. The samples of the research were taken by using the cluster random sampling technique. The research instrument used was a test in the form of description consists of four items. Data acquisition is done by testing with data analysis techniques using U-test (Mann-Whitney U test) because the data is not normally distributed. The result of the research can be concluded that the provision of feedback can influence the students mistakes in completing the algebra arithmetic operation. The effect can be seen by the average difference in students mistakes in completing the algebra arithmetic operation between classes given feedback and classes are not given feedback. Keywords : feedback, students mistakes, algebra arithmetic operation

Abstract

Abstract:This research aims at finding out 1). To find out the average difference in learning outcomes of students learning mathematics using a contextual approach to the learning  style VAK (Visual Auditory Kinesthetic) with a direct approach, 2). Knowing the average results of applied mathematics learning with contextual approach VAK learning styles (Visual Auditory Kinesthetic) higher than the average results of students mathematics learning approach is applied directly to the material of linear equations. The population of this study was all students in grade X MA Al-Hidayah. For data analysis was performed using the formula t-test for normally distributed samples.The conclusions of the research were as follows that the average results of students mathematics learning gained through the application of contextual learning style approach VAK (Visual Auditory Kinesthetic) higher than the average of students mathematics learning outcomes obtained through the direct approach.Keyword : Contextual approach, VAK (Visual Auditory Kinesthetic)
