Abstract

Abstract: The purpose of the research is to improve students' mathematical reasoning ability through knisley mathematics learning model (MPMK). This research uses classroom action research method (PTK). The instruments used are test instruments and nontes. The study was conducted in class X in SMA Negeri 8 Bandar Lampung Lesson 2015/2016 year, subject of 36 students. Having given the knisley mathematics learning model the students' mathematical reasoning ability increases. In cycle 1 formative test 55.56% (less), cycle II formative test 65.86% (less), and cycle III formative test 72.22 (enough). Further research suggestions need to apply the knisley mathematical learning method to the subject, ladder or different mathematical abilities. Abstrak:Tujuan dari penelitian adalah untuk meningkatkan kemampuan penalaran matematis peserta didik melalui model pembelajaran matematika knisley (MPMK). Penelitian ini menggunakan metode penelitian tindakan kelas (PTK). Adapun instrumen yang digunakan adlah instrumen tes dan nontes. Penelitian dilakukan pada kelas X di SMA Negeri 8 Bandar Lampung Tahun Pelajaran 2015/2016, Subjek penelitian 36 peserta didik. Setelah diberikan model pembelajaran matematika knisley kemampuan penalaran matematis peserta didik meningkat. Pada siklus 1 tes formatif 55.56 % (kurang), siklus II tes formatif  65.86% (kurang), dan siklus III tes formatif 72.22 (cukup). Saran penelitian selanjutnya perlu menerapkan metode pembelajaran matematika knisley pada pokok bahasan, jenjang atau kemampuan matematis yang berbeda.

Abstract

This study aims to increase interest in learning mathematics and describe the process of learning mathematics through computer learning media with the MS Power Point program. The research method used is a quasi-experimental method of classroom action research using the PAOR procedure. The results showed that based on the data shown by the results of the questionnaire, interview or observation during the learning process took place, the average results of the questionnaire interest in learning before the action was 62.17%, after the first cycle was 69.70% and after the second cycle was 76, 88% (high) means there is an increase in interest in learning from pre-study to the first cycle of 7.53% and from the first cycle to the second cycle of 7.18%. For the average results of observations of pre-research learning interest is 38.44% in the first cycle is 52.40% and the second cycle is 70.11% From pre-research to the first cycle there was an increase of 13.96%, from the first cycle to the second cycle up 17.71%. Overall from the pre-study to the end of the study there was an increase of 31.67%. This shows that by using computer-assisted learning media MS Power Point program students become more eager to learn mathematics.
