Hasil penelitian menunjukkan bahwa : (1) Rancang bangun pengembangan media pembelajaran puzzle melalui model ADDIE yang terdiri atas analisis (Analyze), rancang bangun (Design), pengembangan (Development), Implementasi (Implementation), dan evaluasi  (Evaluation). (2) Produk dinyatakan valid dilihat dari review para ahli dan uji coba siswa dengan (a) hasil review ahli isi mata pelajaran menunjukkan media pembelajaran puzzle berkualifikasi sangat baik (97,14%), (b) hasil ahli desain pembelajaran menunjukkan media pembelajaran puzzle berkualifikasi baik (88%), (c) hasil ahli media pemebelajaran menunjukkan media pembelajaran puzzle berkualifikasi cukup (70%), (d) hasil uji coba perorangan menunjukkan media pembelajaran puzzle berkualifikasi sangat baik (94%), uji coba kelompok kecil menunjukkan media pembelajaran puzzle berkualifikasi sangat baik (93%), dan uji coba lapangan berkualifikasi baik (87,33%). (3) Uji efektifitas media pembelajaran puzzle menunjukkan bahwa hasil thitung (9,240) > ttabel (2,056). Ini berarti media pembelajaran puzzle efektif untuk meningkatkan hasil belajar siswa kelas IV pada kompetensi pengetahuan IPA di SD Negeri 2 Bengkala, Kecamatan Kubutambahan, Kabupaten Buleleng tahun Pelajaran 2018/2019.

Penelitian ini didasari karena siswa masih kurang disiplin dalam belajar, seperti siswa berbicara dengan teman sebangku saat guru memaparkan materi di kelas. Hal membuat membuat terhambatnya prestasi belajarnya. Karena sikap disiplin sangat penting dimiliiki siswa, karena dengan siswa memiliki sikap disiplin dalam belajar yang tinggi, maka siswa akan memiliki prestasi belajar yang tinggi. Penelitian ini bertujuan untuk mengetahui hubungan antara disiplin belajar dengan prestasi belajar Siswa Kelas V. Jenis dari penelitian in adalah Ex Post Facto. Besar populasi siswa Kelas V dalam penelitian ini adalah 176 siswa, sedangkan untuk jumlah sampel dalam penelitian ini adalah 144 siswa. Data yang di ambil untuk sikap disiplin belajar adalah kuesioner, sedangkan data yang di ambil untuk prestasi belajar adalah pencatatan dokumentasi. Dalam penelitian ini teknik analisis data yang digunakan yaitu teknik statistik deskriptif. Dari hasil penelitian terdapat korelasi antara disiplin belajar dengan prestasi belajar Siswa, dengan koefesienan korelasi rxy hitung 0.89 > r tabel 0.138, yang artinya bahwa terdapat korelasi yang positif dengan kategori hubungan yang sangat kuat dan nilai arah koefisensi regresi dinyatakan bernilai positif. Berdasarkan hasil penelitian, dapat disimpulkan bahwa terdapat korelasi disiplin belajar dengan prestasi belajar Siswa. Sehingga dengan adanya penelitian ini, dapat dijadikan sebagai acuan dalam menambah pengetahuan tentang hubungan disiplin belajar dengan dengan prestasi belajar siswa.

The teachers in elementary schools have not conducted studies and developments as well as changes in the learning process oriented towards the latest student cognitive domains. The proof is that the teacher is only able to make items on the evaluation of learning outcomes that only ask students to utter memorization. This study aims to develop a learning model oriented to the dimensions of knowledge and cognitive processes. This type of research is a development with the Dick & Carey model. The subject of this research is a learning model oriented to the dimensions of knowledge and cognitive processes. Data collection methods used were interviews, documentation, questionnaires, and tests. The data analysis used is the t-test. The results showed that the learning model with the orientation of knowledge and cognitive processes (PSBDPPK) was valid, effective, and efficient to be applied in elementary schools, and the results of the t-test show that this model has a significant effect on student learning outcomes, this is indicated by the t-test, the value (Sig. (2-tailed)) is 0,000. So, it can be concluded that the learning model that crosses the dimensions of knowledge and cognitive processes (PSBDPPK) is valid, effective, and efficient to be applied in elementary schools.

The purpose of this study was to know significant difference of the result study in science subject between groups of students who were taught by using Two Stay Two Stray (TSTS) learning model and group of students who were not taught by using Two Stay Two Stray (TSTS) through learning model in grade V SD students in Gugus XIII Buleleng District AcademicYear 2017/2018. This research was quasy experimental. Research design was Non Equivalent Control Group Design. The population of the research was the students in fifth grade of SD in Buleleng District  in gugus XII on second semesterAcadmic Year 2017/2018. Samples was random sampling technique and it was obtained SD N 3 Banjar Tegal as an experimental group which  numbered16 students and SD Mutiara Penyabangan as a control group which numbered 32 students. Data collected was the test of result study in science subject which included the cognitive aspects that was obtained from result of the multiple choice / objective form. The data obtained can be analyzed inferential statistics (test - t polled variance). Based on the results showed that the average score of result study of the experimental group in science was 27.38 higher than the average score of result studyof control group that was 19.56 in mathematic. This proved that there was a significant difference of result study in science subjectbetween the students who were taught by using the Two Stay Two Stray learning model through the Study Lesson with the students who were not taught by using the Two Stay Two Stray through Lesson Study lesson in grade V SDN 3 Banjar Tegal.

A B S T R A C TThis study is aimed at investigating the difference of students' civics achievement between those who are taught by Think Pair Share model based on concept mapping and those who are taught by conventional learning model of the fifth grade students in Elementary School of Cluster I in Petang District. It is a quasiexperimental research using non-equivalent post-test only control group design. The population of this research is 102 students in grade V in Elementary School of Cluster I Petang District. The samples of this research are fifth grade students of SD Negeri 3 Carangsari as experimental group and fifth grade students of SD Negeri 1 Carangsari as control group. The data of civics achievement were collected by using multiple choice tests. The data obtained were analyzed using descriptive statistics and inferential statistical analysis (t-test). The result showed that tcount= 3,83 and ttable = 2,03 (tcount>ttable) which can be concluded that there are significant difference between the students' civics achievement between those who were taught by Think Pair Share learning model based on concept mapping and those who were taught by the conventional learning model in grade V in Elementary School of Cluster I Petang District of Badung Regency in academic year 2017/2018.
