Abstrak: Penelitian ini bertujuan mengetahui pengaruh penggunaan modeldiscovery learning terhadap keterampilan berpikir kritis siswa kelas IV sekolah dasar. Jenispenelitian adalah eksperimen semu dengan pola equivalent control group design. Subjekpenelitian adalah siswa SD Lab UPI Kampus Cibiru kelas IV-E (kontrol/26 siswa) dan kelasIV-G (eksperimen/26 siswa). Pengumpulan data menggunakan teknik pretes-posttest.Analisis data menggunakan statistik deskriptif dan inferensial parametrik dengan programSPSS for windows 23. Hasil pretest berpikir kritis memperoleh thitung (0,099)< ttabel (1,677),menunjukkan tidak adanya perbedaan berpikir kritis siswa. Hasil posttest berpikir kritismemperoleh thitung (2,591)> ttabel (1,677), menunjukkan ada perbedaan berpikir kritis siswa.Keterampilan berpikir kritis pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol.Berdasarkan analisis data, disimpulkan bahwa model discovery learning berpengaruhpositif terhadap keterampilan berpikir kritis secara signifikan.Kata Kunci: model discovery learning, keterampilan berpikir kritis.

This study aims to determine the effect of using a scientific approach to problem-solving skills related to environmental problems in fourth-grade students in elementary school. This type of research is quasi-experimental with an equivalent control group design. The research subjects were students at SD LAB UPI Kampus Cibiru class IV-A (control/26 students) and IV-B class (experimental/26 students). Data collection used the pre-test – post test technique. Data analysis used descriptive and inferential parametric statistics with SPSS 23.0 for windows program. The result of the problem-solving skills (Pretest) earned tcount (0.087) < ttable (1.677), indicating no difference in problem-solving skills. After being given treatment, problem-solving skills (Post-test) obtain tcount (2.754)> ttable (1.677), indicating there are differences in student problem-solving skills. The problem-solving skills in the experimental class are higher than the control class. Based on data analysis, it was concluded that the scientific approach had a significant positive effect on problem-solving skills related to environmental problems.

This research objective was to improve the environmental concern attitude of grade 4 students by using reading materials. This research is a classroom action research. The research was conducted in two cycles with each cycle consisting of planning, action, observation, and reflection. The subject of this study was the grade 4 students of SDN 5 Panjer which amounted to 24 students. The data sources used in this research were students, teachers, and observers. Data analysis using quantitative and qualitative techniques, including data reduction, data presentation, and drawing conclusions. The results of this research indicate that students environmental concern attitude improved from pre-cycles, cycle 1 and cycle 2. The results of this research indicate that students environmental concern attitude improved from pre-cycles 25%, cycle 1, 48% to cycles 2, 82%. In learning, the teacher uses a reading material based contextual approach with steps: (a) constructivism, (b) inquiry, (c) questioning, (d) learning community, (e) modeling, (f) reflection, (g) authentic assessment. The conclusion of this study is the use of reading materials based contextual approach can improve environmental concern attitude of grade 4 elementary school students.

Learning environmental pollution in the Problem-based learning (PBL) model allows students to improve their science process skills. This research is quasi-experimental due to students were remaining in their classes. In the experimental class, PBL models and control classes were given conventional models. The sample was chosen by simple cluster random sampling technique. Before be implemented, the research instrument was tested for its validity and reliability. Data analysis used descriptive and inferential techniques. Descriptive techniques are used to see of sample representation. Inferential techniques are used to see normality and homogeneous data. Descriptive analysis results show that the score of all indicators of science process skills consists of: observing, interpreting, predicting, using devices and materials, applying concepts, planning experiments and communicating quantitatively is higher in the PBL model group than the conventional model group. The inferential analysis results show that the data obtained is normally distributed and homogeneous. One way ANOVA test results in a significance value = 0.033 < α = 0.05, H0 is rejected. There is a significant effect of the PBL model on science process skills in learning about environmental pollution.

Setiap anak berhak mengenyam pendidikan dasar tanpa terkecuali. Sekolah dasar wajib menyediakan layanan bagi seluruh anak, baik yang normal secara umum maupun anak berkebutuhan khusus. Argumen tersebut diperkuat dengan adanya Convention on the Rights of Persons with Disabilities yang menyerukan bahwa pendidikan inklusi sangat penting untuk diberlakukan. Kenyataannya, banyak sekolah dasar yang belum mampu memberikan layanan bagi anak berkebutuhan khusus. Guru merasa tidak mampu memberikan layanan pendidikan bagi anak berkebutuhan khusus yang masuk di sekolah reguler. Penelitian ini bertujuan untuk menggali informasi mengenai pemahaman guru terhadap anak berkebutuhan khusus serta jenis-jenisnya. Penelitian ini merupakan jenis penelitian kualitatif deskriptif. Data dikumpulkan melalui wawancara memalui media google form dan melalui aplikasi whatsapp dengan triangulasi sumber. Partisipan yakni 28 guru dari empat sekolah di kota Merauke. Hasil penelitian menunjukkan bahwa 92.9% guru sudah mengetahui informasi mengenai apa itu anak berkebutuhan khusus secara umum. Tetapi, sebagian besar partisipan belum mampu memberdayakan karakteristik pada setiap jenis ABK dengan baik. Hal itu menyebabkan guru mengalami kesulitan dalam memberikan layanan pendidikan yang sesuai.
