Abstract

In fact, most of studens thought that Mathematics is difficult,  because  the instruction was dull, teacher was less  active as facilitator in instruction, teacher did not apply imstructional media, teacher didnot involve students enough  in instruction, too many formula but less in practice and also teacher did not maximalized instructional model, as the result, the instruction was ineffective, besides teacher was focuse more  on cognotive oriented domain at class instruction, he left students' affective and pshycomotor domains, so that, their maturnity was less maximal. The objective of study wad to improve students' activities and the  mathematics'score  through geoboard instructional aid. The research was done at seventh hrade of SMP N 3 Metro Lampung on April 2018. It was a Classroom  Action Research. Data collection were observation sheets, tes and questionnaire that was students' response to instruction. It was analysed through descriptive analytic technique. The result of study was the using of  ELPSA model through geoboard assisstance at two dimentional figure could improve the avetage value 55.36 % at cycle I  into 74.49% at cycle ll, and the average result value was 55.06 at cycle ll became 67.41 at cycle ll. Based on the data finding, it can be infered that in appliying mathematis at class teacher should motivate students' interest and also fix the quality of instruction through variation of instructional model and suitable teaching aid,so that students' result can be maximazed

Abstract

Pembelajaran abad 21 memerlukan pemanfaatan media dalam pembelajaran, yang  mengakibatkan keinginan dan minat baru, meningkatkan motivasi dan rangsangan dalam pembelajaran, bahkan berpengaruh secara psikologis kepada siswa. Media pembelajaran berbasis teknologi dapat membuat pembelajaran lebih powerfull, karena penggunaan media dalam proses pembelajaran bukan merupakan fungsi tambahan, tetapi mempunyai fungsi sebagai alat bantu untuk mewujudkan situasi pembelajaran yang aktif, efektif dan menyenangkan. Arus globalisasi yang terjadi saat ini juga mencakup aspek kemajuan dalam penggunaan teknologi informasi, diharapkan tujuan dari penggunaan geogebra dapat meningkatkan motivasi belajar matematika yang divariasi dengan model pembelajaran Discovery Learning. Penelitian ini dilakukan pada kelas IX SMP Negeri 3 Metro pada bulan November 2018  menggunakan metode Penelitian Tindakan Kelas, adapun teknik pengumpulan data menggunakan observasi dan angket motivasi. Analisisnya menggunakan teknik skala likert. Hasil penelitian  ini adalah melalui Discovery Learning dengan Geogebra dapat  meningkatkan motivasi belajar siswa, sehingga aktivitas belajar juga mengalami peningkatan dengan rata-rata 60,83% pada siklus I menjadi 89,38% pada siklus III. Oleh karena itu dalam pembelajaran hendaknya guru dapat berinovasi untuk memotivasi dan meningkatkan kualitas pembelajaran dengan model yang bervariasi dan media yang sesuai, sehingga hasil belajar dapat maksimal. Twenty first century instruction needs media application, which appear  new demand and need, improve learning motivation and stimulate, event it affected students pshycologically. Instructional media which based on technology can create powerfull instruction, because the use of them in instructional process is not as additional function, but they function as device to create active, effective and enjoyable instructional atmosphere. Globalisation streaming nowadays also included the improvement of information  technology  which hoped that the application of Geogebra can improve the motivation on learning mathematic which variated in learning model Discovery Learning. The study was applied at IX grade of State Junioe High School 3 Metro in Movwmber 2018 through Classroom Action Research, The data collection was done using motivation questionnaire, The Analysys was done through  likert scale. Discovery Learning of Geogebra can improve students' learning motivation so that learning activities can be improve too, the score's rate 60.83% at cycle I became 89.38% at cycle II. It can be said that teachers should do innovation to motivate and improve learning quality through variation of models and fixed media in order to gain maximum achievement of learning
