“…In learning physics, students are invited to think about finding solutions to problems associated with the theory (Fatimah et al, 2020). Physics learning should provide direct experience to students to increase the ability to construct, understand, and apply the concepts that have been learned (Firdaus et al, 2019).…”

Mataram City, West Nusa Tenggara Province, has started a transitional period, including in the world of education. The transition to the new normal requires adjusting the learning process to prepare students to learn normally. This study aims to describe students' physics learning outcomes using a blended learning model. This research is a type of experimental research. The research design was pre-experimental with the type of intact group comparison, where this type of research divided one class into two treatment groups. The population in this study were 11th-grade students of private madrasah majoring in science in Mataram city. The research sample was 50 students who were divided into two groups. The two groups were given a different treatment, where group 1 was taught with a blended learning model, while group 2 was taught using an online learning model. The physics learning outcome data were obtained through the initial and final tests, which were then analyzed descriptively using the N-gain test to determine the achievement of the learning process. Based on the research that has been done, it is found that the group taught with the blended learning model has a mean value of 70.14 with an N-gain of 0.36 (included in the medium category), which indicates that the use of blended models can be used to adjust students during a period of transition to a new normal. The use of the blended learning model in the learning process is to accustom students to return to normal learning, namely face to face in madrasah. It was done to increase student motivation to learn during the COVID-19 pandemic.

“…Keadaan bumi yang manusia tempati tidaklah bulat sempurna, jari-jari bumi di khatulistiwa 21 Km lebih besar dari pada jari-jari bumi di kutub (Lasiman, 2007). Semakin tinggi suatu tempat dari permukaan laut maka, semakin kecil percepatan gravitasinya (Firdaus et al, 2019). Dari beberapa penelitian yang sudah dilakukan perlu dilakukan verifikasi dalam variasi yang berbeda dan sangat penting untuk dijadikan bahan ekperimen sebagai informasi pengetahuan bagi pebelajar, dalam penelitian ini menyoroti variasi nilai percepatan gravitasi terhadapa ketinggian MDPL permukaan Bumi, karena beberapa teori menyatakan bahwa percepatan gravitasi dipengaruhi oleh posisi ketinggian dan massa benda sehingga besar percepatan gravitasi di Bumi tiap tempat itu akan berbeda.…”

Penelitian ini menjelaskan konsep fisika terhadap nilai percepatan gravitasi bumi pada gerak jatuh bebas. Percepatan gravitasi bumi yang dialami oleh suatu objek yang berada di permukaan laut khatulistiwa besarnya adalah 9,832 m/s2. Tujuan penelitian ini adalah untuk melihat pengaruh ketinggian MDPL terhadap nilai percepatan gravitasi bumi. Metode dalam penelitian ini adalah eksperimen yang dilakukan pada tempat dan ketinggian (MDPL) yang berbeda-beda. Setiap tempat dilakukan pengambilan data berulang sebanyak mungkin. Data dianalisis menggunakan persamaan matematis fisika percepatan gravitasi untuk gerak jatuh bebas, kemudian dilihat margin error. Hasil penelitian menunjukkan nilai percepatan gravitasi dari enam tempat yang berbeda diantaranya 15 MDPL = 8,52 ± 2,3; 50 MDPL = 9,67 ± 2,9 sampai 237 MDPL = 10,23 ± 2,6 dan rata-rata tingkat kesalahan 27 %. Data dilakukan fitting dengan menggunakan persamaan linier y = ax + b dalam bentuk grafik korelasi dengan R2 = 0.65 dengan kategori cukup.

“…The range, breadth and depth of topics discussed at each level vary according to the area of expertise of the lecturer/teacher [3]. Even though the concept of free fall motion has been obtained before and is often found in everyday life, there are still many students who experience misconceptions about speed, free fall acceleration and gravitational acceleration [4][5][6].…”

“…Free fall motion media is used in physics learning to visually explain to students the concept of free fall motion. This media is proven to reduce misconceptions and increase understanding of physics concepts [4]. It was also revealed that most students had misconceptions about acceleration, assuming that in each case it would have the same impact, namely acceleration depending on the motion of the object [3].…”

The purpose of this research is to understand the physics education concepts through solving unit review problems in free fall topic. This research is a quantitative descriptive study involving 19 students of Physics Education at the University of Tamansiswa. The test instrument consists of 2 essay questions that refer to problem-solving indicators. The results of the study obtained several findings. Analysis of understanding the concepts of physics education students through solving unit review problems in free fall topic had the highest percentage in the medium category. On the problem solving indicators Physics Approach, Specific Application of Physics, and Logical Progression students’ abilities are in the low category.
