Problem-based learning math is forming children critical thinking in solving problems. Therefore, it can make children whose character so as to answer the question of educational quality improvement is expected in particular on education in elementary schools. The purpose of this research is to develop a problem-based learning math in elementary school. This study uses classroom action research approach. The results obtained in this study showed an increase in math skills of elementary school students

In this study aims to determine the effect of problem-based learning models on students' understanding of nationalism and patriotism of elementary school students as citizens. This type of research is an experimental study in the form of a pretest-posttest control group design research design. Hypothesis testing results explain the calculated t value obtained is equal to 5,216 and a significance value of 0,000, the hypothesis testing results indicate that the calculated t value obtained is greater than the t value in the table (5.216> 2.408) while the significance value is smaller than the α value (0,000 <0.05). Based on these results, the hypothesis is accepted, meaning that there is a significant influence between problem-based learning, on students' understanding of nationalism and patriotism of elementary school students as citizens.

Pelaksanaan penelitian ini dimaksudkan untuk mengetahui apakah dalam mengaplikasikan model Problem Based Learning dapat meningkatkan keaktifan dan keterampilan berpikir kritis siswa. Subjek penelitian yang digunakan ialah siswa kelas IV SD Negeri 2 Bojong yang memiliki jumlah 23 siswa, terdiri dari 15 siswa laki-laki dan sisanya perempuan berjumlah 8 siswa. Jenis penelitian yang dipakai ialah Penelitian Tindakan Kelas jenis Classroom Research dengan menggunakan model Kemmis & McTaggart. Pelaksanaan tindakan kelas ini diterapkan sejumlah 2 siklus, yaitu pra siklus, siklus I, dan siklus II. Per-siklus terdiri dari 4 tahap, yakni perencanaan, pelaksanaan tindakan, pengamatan, dan refleksi. Penelitian dilakukan pada semester II tahun ajaran 2020/2021. Pelaksanaan teknik penghimpunan data menggunakan tes dan non tes, sedangkan instrumen penelitian memakai soal uraian, lembar observasi, dan rubrik. Teknik analisis data yang digunakan oleh peneliti yakni teknik deskriptif komparatif. Hasil penelitian pada kondisi mula-mula atau pra siklus, keaktifan yang dicapai siswa terhitung 37,93%. Siklus I terhitung 60,82% dan pada siklus II mengalami kenaikan menjadi sebanyak 76,02%. Sedangkan saat siklus I, KKM yang dicapai atau siswa yang sudah memenuhi syarat berpikir kritis diakumulasikan dengan rata-rata sejumlah 63,78 dan pada siklus II siswa yang telah berpikir kritis meningkat dengan rata-rata 82,30. Oleh sebab itu, dapat dicapai kesimpulan bahwa keaktifan dan keterampilan berpikir kritis bisa ditingkatkan dengan cara menerapkan model Problem Based Learning.

This research was conducted to determine the effect of PBL learning models on improving understanding of concepts, and improvement of misconceptions of  grade V elementary school students in science lessons, and to find out the increase in understanding of the concepts and misconceptions of V grade elementary school students. The research was conducted in elementary schools in the District of North Sumedang Sumedang as an experimental class and one of the elementary schools in Cibugel District, Sumedang Regency as a control class. The research method used was pre-experimental research design with pretest-posttest control design. The results of this study indicate: 1) Knowing the effect of PBL models on understanding concepts based on the t test is 0.05 (0,000 <0.05), this shows that PBL models have a significant influence on concept understanding. 2) Knowing the effect of PBL models on students 'misconceptions shows the results of t test as follows 0.05 (sig. 0,000 <0.05), PBL learning models have a significant influence on the improvement of students' misconceptions. 3) Based on the test withney posttest the control class and the experimental class showed (sig. 0,000 <0.05), based on the calculation of the control class gain an average of 0.58 while the average value of the experimental class gain of 0.71 in the high category. 4) An increase in the misconception of the experimental class students was seen from the results of the pretest-posttest test of the experimental class which showed (sig. 0,000 <0.05), Calculation of experimental class gain shows the number 0.71 in the high category, while the control class gain test results show the number 0.44 in the medium category.   Abstrak Penelitian ini dilakukan untuk mengetahui pengaruh model pembelajaran PBL terhadap peningkatan pemahaman konsep, dan perbaikan miskonsepsi siswa kelas V SD dalam pelajaran IPA, serta untuk mengetahui peningkatan pemahaman konsep dan miskonsepsi IPA siswa kelas V SD. Penelitian ini dilaksanakan di  Sekolah Dasar yang ada di Kecamatan Sumedang Utara Kabupaten Sumedang sebagai kelas eksperimen dan salah satu Sekolah Dasar yang ada di Kecamatan Cibugel Kabupaten Sumedang sebagai kelas kontrol. Metode penelitian yang digunakan adalah pre-eksperimental dengan desain penelitian pretest-posttest control design. Hasil penelitian ini menunjukan: 1) Mengetahui pengaruh model PBL terhadap pemahaman konsep berdasarkan uji t adalah 0,05 (0,000<0,05) hal ini menunjukan model PBL memberikan pengaruh yang signifikan terhadap pemahaman konsep. 2) Mengetahui pengaruh model PBL terhadap miskonsepsi siswa menunjukan hasil uji t sebagai berikut 0,05 (sig. 0,000<0,05), model pembelajaran PBL memberikan pengaruh yang signifikan terhadap perbaikan miskonsepsi siswa. 3) Berdasarkan uji withney postes kelas kontrol dan kelas eksperimen menunjukan (sig. 0,000<0,05), berdasarkan penghitungan gain kelas kontrol rata-ratanya 0,58 sedangkan nilai rata-rata gain kelas eksperimen sebesar 0,71 dalam kategori tinggi. 4) Peningkatan miskonsepsi siswa kelas eksperimen dilihat hasil pengujian pretest-postest kelas eksperimen yang menunjukan (sig. 0,000<0,05). Penghitungan gain kelas eksperimen menunjukan angka 0,71 kategori tinggi, sedangkan hasil pengujian gain kelas kontrol menunjukan angka 0,44 kategori sedang.
