ABSTRAK

Latar belakang yang mendorong penelitian ini adalah rendahnya hasil belajar siswa kelas IV pada mata pelajaran matematika, kurangnya antusias siswa terhadap pembelajaran, fasilitas pembelajaran terbatas dan perbedaan pemahaman siswa. Hal tersebut disebabkan kurangnya pembelajaran yang efektif dalam mengoptimalkan kemampuan pemahaman konsep siswa.  Permasalahan dalam penelitian ini adalah 1). Apakah Media gabiltal menggunakan Model Everyone is a Teacher Here efektif  pada kemampuan memahami konsep mata pelajaran matematika kelas IV SD Negeri Tlogosari Wetan 01 Semarang?  Jenis penelitian ini adalah penelitian kuantitatif True Eksperimental Design dengan desain Posttest Only Control Design. Populasi penelitian adalah semua siswa SDN Tlogosari Wetan 01 Semarang tahun pelajaran 2017/2018. Sampel yang diambil adalah 48 siswa kelas IV A dan IV B dengan menggunakan teknik Probability Sampling berbentuk Cluster  Sampling. data penelitian ini diperoleh dari tes, dokumentasi dan observasi.   Hasil analisis kemampuan pemahaman konsep matematika bahwa presentase klasikal kelompok eksperimen (96%) lebih dari kelompok kontrol (71%), serta berdasarkan hasil uji t diketahui  𝑡ℎ𝑖𝑡𝑢𝑛𝑔 lebih dari 𝑡𝑡𝑎𝑏𝑒𝑙 ( 5,2971 >0, 2887) . Kesimpulannya adalah media gabiltal menggunakan model everyon teacher here efektif pada kemampuan pemahaman konsep matematika. Ketuntasan klasikal kelas eksperimen dengan presentase ketuntasan 96% sedangkan ketuntasan pada kelas kontrol 71%. Disimpulkan bahwa melalui media gabiltal menggunakan model everyone is a teacher here siswa dapat mencapai ketuntasan belajar. perbedaan hasil belajarnya 25%. Kesimpulan media gabiltal menggunakan model everyone is a teacher here efektif pada kemampuan pemahaman konsep siswa.   Berdasarkan hasil penelitian ini saran yang dapat disampaikan adalah supaya media gabiltal menggunakan model everyone is a teacher here dapat digunakan salah satu alternatif guru dalam mengajar.

ABSTRACT

The backgrounds that encourage this research are the low learning outcomes of fourth grade students in mathematics subjects, the lack of enthusiasm of students towards learning, limited learning facilities and differences in students' understanding. This is due to the lack of effective learning in optimizing the ability to understand students' concepts.  The problems in this research are 1). Does Media Gabiltal use the Model Everyone is a Teacher Here effective in understanding the concept of the fourth grade mathematics course SD Negeri Tlogosari Wetan 01 Semarang?This type of research is Quantitative True Experimental Design with Post-test Design Only Control Design. The study population is all students of SDN Tlogosari Wetan 01 Semarang of academic year 2017/2018. Samples taken were 48 students of class IV A and IV B by using Probability Sampling technique in the form of Cluster Sampling. This research data obtained from the test, documentation and observation. The result of the mathematical concept comprehension analysis shows that the classical percentage of the experimental group (96%) more than the control group (71%), and based on the result of t test is known t_hitunglebih than t_tabel (5,2971> 0, 2887). The conclusion is the gabiltal media using the model everyone is a teacher here effective on the ability of understanding mathematical concepts. The classical completeness of the experimental class with 96% mastery percentage while the completeness in the control class is 71%. It was concluded that through the gabiltal media using the model everyone is a teacher here the students can achieve learning mastery. Difference of learning result 25%. The conclusion of the gabiltal media using the model of everyone is a teacher here is effective in students' conceptual comprehension skills.  Based on the results of this study suggestions that can be delivered is that the gabiltal media using the model everyone is a teacher here can be used one alternative teacher in teaching.
