Abstract

Penelitian ini bertujuan untuk mengetahui apakah ada hubungan antara nilai UAS matematika semester gasal dengan nilai UAS matematika semester genap pada siswa kelas VII SMP Negeri se-Kecamatan Kaliwiro Tahun Pelajaran 2012/2013. Jenis penelitian ini merupakan penelitian korelasi. Populasi dalam penelitian ini adalah semua siswa kelas VII SMP Negeri se-Kecamatan Kaliwiro yang berjumlah 601 siswa. Teknik sampling yang digunakan adalah Simple Random Sampling. Sampel berjumlah 222 siswa.Teknik pengumpulan data dengan metode do-kumentasi. Statistik uji yang digunakan untuk menguji hipotesis adalah korelasiKendal Tau dan uji signifikansinya menggunakan ujiz. Dari hasil pengolahan data diperoleh koefisien korelasi sebesar 0,486yang berarti ada hubungan yang positif antara nilai UAS semester gasal dengan nilai UAS semester genap. Untuk uji signifikansi diperoleh zhitung = 10,795 dan ztabel = 1,96se-hingga zhitung> ztabel. Ini berarti terdapat hubungan yang signifikan antara nilai UAS matematika semester gasal dengan nilai UAS matematika semester genap.   Kata Kunci: UAS matematika, semester gasal, semester genap

Abstract

This research aims to describe the mathematical representation ability of students grade XI in online learning through a flipped classroom which was assisted by learning videos. It employed the mixed method specifically the concurrent embedded design. The subject of the research was determined based on the self-efficacy score from a self-efficacy questionnaire of the students grade XI at SMA N 1 Selomerto, Wonosobo. The tests, questionnaires and interviews were employed to collect the data. The effect of self-efficacy on mathematical representation ability was analyzed based on a simple linear regression test. The results showed that (1) students with high self-efficacy were able to master all indicators of mathematical representation well compared to students with moderate and low self-efficacy; (2) self-efficacy has a positive effect on the mathematical representation ability in online learning through flipped classroom.
