Penelitian ini termasuk jenis penelitian tindakan kelas (PTK) yang dilakukan sebanyak 2 siklus terhadap 41 subyek. Data diperoleh dengan cara melakukan kegiatan observasi dan juga tes secara tertulis. Pada penelitian ini terlihat bahwa hasil belajar siswa kelas V pada mata pelajaran PKn ini mengalami peningkatan. Pada tes siklus I nilai rata-ratanya 61,15 dan pada saat tes siklus II nilai rata-ratanya menjadi 77. Jika dipersentasekan maka nilai ketercapaian pada siswa kelas V di siklus I 46% dan pada siklus II 70,4%. Meningkatnya hasil belajar pada siswa kelas V pada siklus II disebabkan oleh adanya peningkatan aktivitas belajar saling ketergantungan yang positif 38%, interaksi tatap muka 78%, tanggungjawab individu 32%, keterampilan komunikasi antar kelompok dan individu 50%, dan evaluasi proses perkelompok 32%. Pada siklus II, saling ketergantungan yang positif 60%, interaksi tatap muka 83%, tanggungjawab setiap individu 63%, keterampilan komunikasi antar kelompok dan individu 73%, dan yang terakhir itu evaluasi proses perkelompok 73%. Dari penelitian ini dapat disimpulkan bahwa dengan melakukan implementasi model STAD ini sangat baik untuk meningkatkan hasil belajar dan aktivitas siswa pada pembelajaran PKN di kelas V SDN 125558 Siantar Sitalasari.

This research is a type of classroom action research (PTK) which was conducted in 2 cycles on 41 subjects . The data were obtained by carrying out observation activities and also written tests. In this study, it can be seen that the learning outcomes of class V students in this Civics subject have increased. There is a test cycle I the average value is 61,15 and at the time of the second cycle test the average score becomes 77. If a percentage, the achievement value in class V students in cycle I is 46% and in cycle II is 70.4%. The increase in learning outcomes in class V students in cycle II was caused by an increase in positive interdependence learning activities 38%, face-to-face interaction 78%, individual responsibility 32%, communication skills between groups and individuals 50%, and group process evaluation 32%. In cycle II, positive interdependence is 60%, face-to-face interaction is 83%, responsibility for each individual is 63%, communication skills between groups and individuals are 73%, and the last is evaluation of the group process 73%. From this research it can be concluded that by implementing the STAD is very good for improving learning outcomes and student activities in PKN learning in class V SDN 125558 Siantar Sitalasari.

This study aims to determine the feasibility and effectiveness of teaching aids and to develop multiplication board aids based on Montessori in order to improve the ability to calculate multiplication and create a more interesting and enjoyable learning process for class II MIN 12 students in Medan City. This study uses the Research and Development (R&D) method using research and development procedures from Borg and Gall with 8 steps out of 10 steps namely: research and data collection, planning, product draft development, initial field trials, product revisions, field trials main, operational test and final product revision. Data collection techniques with observation, interviews, questionnaires and tests. Data analysis techniques using quantitative descriptive statistics. From the results of validation by material experts, media experts and field trials conducted by teachers and students it can be seen that they fall into the very feasible category. This is indicated by an increase in student learning outcomes of 58,6%. The results of field trials also found that visual aids had cognitive and affective impacts in the form of increasing students' concentration and interest in learning.

The purpose of this study was to determine the correlation between the auditory, intellectual, and repetition learning models on the learning achievement of Santri at LPBA (PP Mambaul Ulum Bata-Bata), while the method used was a quantitative research method with analysis using product moment correlation. The results of the research after the manual analysis showed that the r count was 0.676, higher than the r table value of 0.235, so that the r count was in the range of 0.600 to 0.800 with a high interpretation. The conclusion from this study is that auditory, intellectual, and repetition (AIR) learning have a high relationship with the learning achievement of students at the Arabic Language Development Institute (LPBA) in PP. Mambaul Ulum Bata-Bata is accepted because the work "r" value is 0.676 in the range of numbers between 0.600 and 0.800 with a high interpretation. This is supported by observational data, interviews, and documentation.

<p><strong><em>This study aims to determine the implementation of PKN learning assessment in the pandemic period in Class IV of Al-Fauzi Elementary School. This study is a qualitative descriptive study with the research subject of grade IV-A teacher of SDIT Al-Fauzi. Research data were obtained through interview techniques and documentation techniques. Then the data were analysed to get an overview of the implementation of PKN learning assessments in pandemic times. Based on research results showing the performance of PKN learning assessment in the pandemic period in Class IV of Al-Fauzi Elementary School conducted online through WhatsApp and face-to-face through home visit application. PKN learning assessment activities are carried out by giving questions in the form of objective tests, i.e., multiple-choice tests and essay tests, to students who are then conducted assessments by teachers. The impediment to the implementation of PKN learning assessment in pandemic times is that the mobile phone used by the teacher had experienced errors due to a large number of photos of students' assignments to be assessed.</em></strong></p>
