This research is motivated by the result of a preliminary study, which shows that there are many educators who apply assessment only to find out the student learning outcomes at the end of learning. Therefore, an assessment is needed that can improve students' understanding during learning, known as a formative assessment. The purpose of this study is to know the effectiveness of formative concept checks on students' cognitive abilities. The research method was used a quasi-experimental design with one group pretest-posttest design. The sample in this study was class X students senior high school in Bandung, an amount of 59 students. The data collection was conducted through a cognitive abilities test. The data were analyzed using the t-test and effect size. The results showed that there was a difference in the increased cognitive ability of students between the experimental class and the control class and the effect size value included in the medium category. This shows that the integration of formative assessment concept checks in physics learning was effective in improving the cognitive abilities of students.

Abstrak. Selama satu tahun, Matahari tidak selalu berada di daerah khatulistiwa, namun terkadang berada di daerah utara khatulistiwa serta daerah selatan khatulistiwa. Kedudukan Matahari di khatulistiwa disebut ekuinoks, kedudukan Matahari saat berada di titik terjauh di utara dari khatulistiwa disebut solstis musim panas ( summer solstice ), kedudukan Matahari saat berada di titik terjauh di selatan dari khatulistiwa disebut solstis musim dingin ( winter solstice ). Matahari di Observatorium Ilmu Falak Universitas Muhammadiyah Sumatera Utara menunjukkan posisi yang berbeda saat ekuinoks, summer soltice , dan winter solstice . Matahari terbit di arah timur dan terbenam di arah barat hanya terjadi pada saat ekuinoks. Meskipun saat ekuinoks, namun Matahari tidak dapat menunjukk arah timur dan barat sepanjang hari. Hal ini disebabkan pergerakan Matahari tidak tegak lurus terhadap horizon melainkan miring sesuai dengan lintang tempat. Abstract. During one year, the Sun is not always in the equator, but sometimes it is in the north of the equator and the south of the equator. The position of the Sun at the equator is called the equinox, the position of the Sun when it is at its farthest point north of the equator is called the summer solstice, the position of the Sun when it is at the farthest point south of the equator is called the winter solstice. The Sun at Obervatorium Ilmu Falak Universitas Muhammadiyah Sumatera Utara shows a different position during the equinox, summer solstice, and winter solstice. The sun rises in the east and sets in the west only at the equinox. Even at the equinox, the Sun can't show east and west all day. This is due to the movement of the Sun not perpendicular to the horizon but tilted in accordance with the latitude of the place.
抽象。有一年的时间，太阳并不总是在赤道附近，但有时它位于赤道的北部和赤道的南部。太阳在赤道的位置被称为春分，而太阳在赤道最北端的位置被称为夏季冬至，而太阳在赤道最南端的位置被称为冬季冬至。太阳在北苏门答腊大学的天文观景器上显示出春分、夏至和冬至的不同位置。太阳从东方升起，从西方落下，这只发生在春分的时候。即使是春分，太阳也不能整天东西方。这是因为太阳的运动不是垂直于地平线，而是根据纬度倾斜。抽象。在一年的时间里，太阳并不总是在equator，但有时它在equator的北部和南部。《孙at The equator位置是叫《位置》,孙的春分的时候是在它的北方farthest point of The equator是叫《夏至,太阳位置》当是at The farthest point (south of The equator是叫《冬天的冬至。太阳在东方、夏至和冬至期间展示不同的位置。太阳在东方升起，在西方升起，只在春分。即使在春分，太阳也不能整天东西方炫耀。这取决于太阳的运动，而不是垂直地延伸到地平线，而是根据地点的纬度倾斜。

Abstrak. Kajian fenomena resonansi kolom udara yang ujungnya terbuka sebagian belum pernah ditemukan dalam materi pembelajaran fisika, menyebabkan pengetahuan konsep mahasiswa tentang resonansi kolom udara tidak utuh. Telah dilakukan perancangan alat sederhana dan penyelidikan resonansi sistem kolom udara berdasarkan variasi luas ujung terbuka untuk mengetahui pola hubungan antara variasi luas ujung pipa terbuka dengan frekuensi. Eksperimen ini dilakukan dengan suling pipa PVC tanpa lubang nada yang ditiup dengan alat sederhana yang dirancang sebagai kompresor balon. Sinyal suara yang dihasilkan direkam dengan software Audacity dan kandungan frekuensi harmonik dianalisis dengan algoritima Fast Fourier Transform ( FFT ). Hasil eksperimen menunjukkan bahwa variasi luas ujung pipa terbuka dari sistem kolom udara berpengaruh terhadap frekuensi bunyi secara logarithmic . Implikasi konsep ini dapat dijadikan sebagai bahan pertimbangan untuk mengembangkan diafragma pengatur luas ujung alat musik tiup sebagai pengatur tuning nada mengingat kebanyakan alat musik tiup tidak memiliki bagian penyetem nada. Abstract. Studies the resonance phenomenon at the open end partially of a pipe never been found in physics learning material, causing the students conceptual about pipe resonance to be incomplete. Simple apparatus and investigation of resonance pipe systems have been carried out based on the variation of open-end area to know the relationship with the frequency using a PVC flute pipe without tone holes and blown with a simple balloon compressor. Sound signals generated are recorded by Audacity software and to analyze the harmonic frequency content using the Fast Fourier Transform (FFT) algorithm. The results of this study show that the variation wide of the open end of the air column significantly influences the sound frequency as logarithmic. The implication of this concept can be used as a diaphragm to regulates the wide-open end of a wind instrument as a tuning tone.

Abstrak. Penelitian ini dilatar belakangi oleh Skor TIMSS bidang fisika Indonesia sangat rendah dan berada di bawah rata-rata internasional, hal tersebut disebabkan karena pembelajaran fisika di Indonesia kurang merangsang dan kurang dapat meningkatkan kemampuan tingkat tinggi.. Maka masalah pokok yang akan dicari pemecahannya melalui penelitian ini adalah perbedaan pemahaman konsep antara kelompok peserta didik yang belajar mengunakan model pembelajaran REACT berbantuan virtual laboratory, peserta didik yang belajar menggunakan model pembelajaran REACT dan model pembelajaran konvensional. Tujuan penulisan ini adalah mendeskripsikan pengaruh model REACT berbantuan virtual laboratory terhadap pemahaman konsep. Metode yang digunakan yaitu studi kepustakaan. Jadi, dapat disimpulkan model pembelajaran REACT dengan berbantuan virtual laboratory akan meningkatkan pemahaman konsep pada materi kesetimbangan benda tegar. Abstract. This research is motivated by the TIMSS score in the Indonesian physics field which is very low and below the international average, this is because learning physics in Indonesia is less stimulating and less able to improve high-level skills. Then the main problem that will be solved through this research is the difference in concept understanding between groups of students who learn to use REACT learning models assisted by virtual laboratories, students who learn to use REACT learning models, and conventional learning models. The purpose of this paper is to describe the effect of a virtual laboratory-assisted REACT model on understanding concepts. The method used is a literature study. So, it can be concluded that the REACT learning model with the assistance of a virtual laboratory will increase the understanding of concepts in the equilibrium of rigid bodies.

Penelitian ini dilatar belakangi oleh Skor TIMSS bidang fisika Indonesia sangat rendah dan berada di bawah rata-rata internasional, hal tersebut disebabkan karena pembelajaran fisika di Indonesia kurang merangsang dan kurang dapat meningkatkan kemampuan tingkat tinggi.. Maka masalah pokok yang akan dicari pemecahannya melalui penelitian ini adalah perbedaan pemahaman konsep antara kelompok peserta didik yang belajar mengunakan model pembelajaran REACT berbantuan virtual laboratory, peserta didik yang belajar menggunakan model pembelajaran REACT dan model pembelajaran konvensional. Tujuan penulisan ini adalah mendeskripsikan pengaruh model REACT berbantuan virtual laboratory terhadap pemahaman konsep. Metode yang digunakan yaitu studi kepustakaan. Jadi, dapat disimpulkan model pembelajaran REACT dengan berbantuan virtual laboratory akan meningkatkan pemahaman konsep pada materi kesetimbangan benda tegar. Abstract. This research is motivated by the TIMSS score in the Indonesian physics field which is very low and below the international average, this is because learning physics in Indonesia is less stimulating and less able to improve high-level skills. Then the main problem that will be solved through this research is the difference in concept understanding between groups of students who learn to use REACT learning models assisted by virtual laboratories, students who learn to use REACT learning models, and conventional learning models. The purpose of this paper is to describe the effect of a virtual laboratory-assisted REACT model on understanding concepts. The method used is a literature study. So, it can be concluded that the REACT learning model with the assistance of a virtual laboratory will increase the understanding of concepts in the equilibrium of rigid bodies.","PeriodicalId":17730,"journal":{"name":"Jurnal Riset dan Kajian Pendidikan Fisika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47488480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
