Penelitian ini bertujuan untuk mengetahui pengaruh strategi pembelajaran aktif tipe everyone is teacher here (eth) terhadap minat belajar matematika pada siswa kelas vii mts ddi tarakan. penelitian ini dilaksanakan pada tanggal 05 mei–18 mei 2017 di mts ddi tarakan. jenis penelitian ini adalah quasi exsperimental research dengan desain posttest only control design. populasi dalam penelitian ini adalah seluruh kelas vii mts ddi tarakan. sampel penelitian ini adalah kelas vii-a sebagai kelas eksperimen dan vii-b sebagai kelas kontrol, sampel penelitian diambil dengan teknik simple random sampling. teknik pengumpulan data dalam penelitian ini menggunakan angket dan lembar observasi. data dianalisis menggunakan analisis statistik deskriptif dan analisis statistik inferensial. analisis deskriptif meliputi rata-rata hitung dan simpangan baku. analisis statistik inferensial menggunakan uji statistik independent sample t- test dengan bantuan software spss versi 16.0 for windows. hasil analisis deskriptif menunjukkan bahwa nilai rata-rata minat belajar matematika kelas eksperimen adalah 75,95 dan nilai rata-rata minat belajar matematika kelas kontrol adalah 62,00. sedangkan berdasarkan hasil analisis uji independent sample t-test dengan taraf signifikan 5% (a = 0,05) diperoleh p-value sebesar 0,000. sehingga dapat dilihat bahwa 0,000 < 0,05. dengan demikian ho ditolak dan ha diterima, artinya nilai rata-rata minat belajar matematika siswa pada kelas eksperimen lebih tinggi secara signifikan dari nilai rata-rata minat belajar matematika siswa pada kelas kontrol. sehingga dapat disimpulkan terdapat pengaruh strategi pembelajaran aktif tipe everyone is teacher here (eth) terhadap minat belajar matematika pada siswa kelas vii mts ddi tarakan. kata kunci: everyone is teacher here (eth), minat

The objective of this research is to find out the effect of guided active learning strategy on the type everyone is teacher here (eth) toward mathematic students’ interest at the seventh-grade class of mts ddi tarakan. this research was held on 05 may – 18 may 2017 in mts ddi tarakan. the type of this research is quasi experimental research by posttest only control design. the population of this research is all the seventh-grade students’ of mts ddi tarakan. the sample of this research is class vii-a as an experimental and class vii-b as a control group. the sample was taken by using simple random sampling. this study used questionnaire and observation in collecting the data. the technique of data analysis is descriptive and inferential analysis. descriptive analysis included the mean and standard deviation. inferential analysis which using independent sample t-test helped by software spps version 16.0 for windows. descriptive analysis showed that the average score the ability of interest experimental class was 75,95 and the average score the ability of interest on the control class is 62,00. while, based on the analysis of test independent sample t test with significance level of 5% (a = 0,05) obtained p-value is 0,000. it can be seen that 0,000 < 0,05. it means that ho was rejected and ha was accepted. that means, the average ability of the mathematic students’ interest in the experimental class was significantly higher than the average in the control class. so that, it can be concluded there are significantly active learning strategy on the type everyone is teacher here (eth) to the students’ ability interest at the seventh-grade students of mts ddi tarakan. keywords: everyone is teacher here (eth), interest
