The online learning process creates problems that the practicum cannot be carried out during the online learning process. This problem has an impact on the decline in the level of understanding of students' scientific concepts and process skills. Researchers used a PhET-based STEM approach to overcome these problems. The purpose of this study was to determine the impact of the PhET-based STEM approach in improving students' conceptual understanding of physics subjects at SMA N 5 Banda Aceh. Data collection for this study was conducted in March. Analysis of the data used is a statistical test that is independent-t test. The results show that the use of the PhET-based STEM approach has a very positive impact on improving the understanding of physics concepts that are tested through objective tests. The results of the variable understanding of the concept can be seen from the N-Gain. In the concept understanding variable, the experimental class got a gain value of 0.6 and the control class was 0.5. Both fall into the medium category. So it can be concluded that the PhET-based STEM approach can improve students' conceptual understanding in physics.

This study aimed to explore the effectiveness of modeling instruction based on a system for improving student’s understanding of energy concepts on high school students. This Research was a mixed-method design with an embedded experimental model. The subject of this study was the 62 students of 11th grade, at Senior High School in Nganjuk, Indonesia. Modeling instruction based on system learning could significantly improve students' understanding of concepts better than conventional learning. Based on the calculation of the effectiveness of learning using N-gain obtained for 0.33 (medium or low medium category) for the treatment class and 0.18 (low category) for the control class. It concluded that improved students' conceptual understanding of the treatment class was better than the control class. This research also was identified student’s difficulties especially in differentiating forces and work. Students propensity to use p-prime in solving problems rather than using energy theorems.

Abstract: Competency standards needed by a lecturer in carrying out their work require the lecturer to master the curriculum, learning material, education policies, understanding the characteristics and content of learning materials, mastering the concept, understanding the context of science with society and the environment, the impact and realization of that knowledge in the life of society . This study aims to determine the effect of the quality of lecturer learning on student teaching skills. This research is quantitative. The conclusion of this study is that there is a significant influence between the Quality of lecturer learning with student teaching skills. Based on Anova's table image, it is known that the value of Sig = 0.029 <0.05. If the value of Sig <from α (0.05) then Ho is rejected. That is, the variable teaching skills of students are affected by the quality of lecturer learning.Keyword : lecturer learning, teaching skills, learning processAbstrak: Standar kompetensi yang diperlukan seorang dosen dalam menjalankan pekerjaannya mengharuskan dosen untuk menguasai kurikulum, materi pembelajaran, kebijakan- kebijakan pendidikan, pemahaman pada karakteristik dan isi bahan pembelajaran, menguasai konsep, memahami konteks ilmu dengan masyarakat dan lingkungan, dampak dan realisasi ilmu tersebut dalam kehidupan masyarakat. Penelitian ini bertujuan untuk mengetahui  pengaruh kualitas pembelajaran dosen terhadap keterampilan mengajar mahasiswa. Penelitian ini bersifat kuantitatif. Kesimpulan penelitian ini yaitu terdapat pengaruh yang signifikan antara kualitas pembelajaran dosen dengan keterampilan mengajar mahasiswa. Berdasarkan gambar tabel Anova diketahui nilai Sig = 0,029 < 0,05. Apabila nilai Sig < dari α (0,05) maka Ho ditolak.

The Impact

This study aims to investigate the improvement of students' mathematical concepts understanding through the application of Guided, Explained, Collaborated & Evoked (GECE) Learning Strategy. The GECE Learning Strategy originates from the integration of the Auditory Intellectually Repetition (AIR) learning model and Guided Discovery learning model. The quasi-experimental with nonequivalent control group design was employed in this study. The instruments used were a test in the form of a description based on real-world concepts and a questionnaire to determine students' responses in the process of learning mathematics. Based on the results of hypothesis testing using the Mann-Whitney test, it was obtained that p <α (0.001 <0.005) which shows that the application of the GECE learning model affects students' mathematical concept understanding with n-gain of 0.62 (medium category). The effectiveness of the learning model applied was measured using Cohen's formula and a value of 1.88 (high category) was obtained. The results were also supported by positive students' responses of 3.45 which means that the integration of the Auditory Intellectually Repetition (AIR) learning model and Guided Discovery learning model could effectively improve students' mathematical concepts understanding.

The Impact

The phenomena accompanying the impact of large meteorites on the surface of the Moon or of the Earth can be examined on the basis of the theory of explosive phenomena if we assume that, instead of an exploding meteorite moving inside the rock, we have an explosive charge (equivalent in energy), situated at a certain distance under the surface.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.
