In the 21st century the world entered the era of globalization as a result of the development of Science and Technology (Science and Technology). This is marked by competition in various fields of life. For this reason, it is demanded that everyone can master the science and technology and be able to adapt to their environment.. Learning physics in the 21st century is different from before. The 21st century, known as the technology age, requires teachers to have teaching skills, including utilizing technology in learning). Physics is one part of natural science that underlies the development of science and technology. Physics is the study of natural phenomena related to matter and energy. This study aims to analyze the effect of virtual laboratory media on student competencies in terms of education levels and physics learning materials. The research method is a meta-analysis with a sample of 17 articles in national journals and 3 articles in international journals. The instrument used in this study was the code sheet and the effect size calculation. Based on the results of the study it can be concluded that: 1) Virtual laboratory media provides a high positive influence on student competence (0.84), 2) the influence of virtual laboratory media on student competencies based on education levels is more effectively used at high school education levels and 3) the influence of media virtual laboratory on the competence of students based on physics learning material very high influence (1.17) on alternating current material.

This study aims to determine the meta-analysis of the development of integrated learning modules in environmental literacy in terms of validity, practicality and effectiveness. This research method is a meta-analysis method. The population in this study are all written documents regarding educational research that discuss modules with integrated environmental literacy. The sample used was 10 journals consisting of national and international journals. Data collection techniques in this study using documentation techniques. The instrument for data collection is an observation sheet with data coding . The average value of validity of the ten journals is 0.80 with a valid category, while the average practicality is 0.61 with a high practicality category. Effectiveness test to determine the effect size of each journal in terms of levels of education, subjects and influence after use. Based on the level of education the highest effect size at the level of junior high school with a value of 1.28, for subjects that are science with a score of 0.71, while for the aspect of influence after use there is an attitude of environmental care with a value of 1.62. Thus the integrated learning module environment literacy is valid, practical and effective to be used for junior high school level, natural science subjects and can improve students' environmental care attitudes.

Indonesia was one of the countries which was frequently shook by earthquake. School education was believed could be the right institution for giving understanding about earthquake materials. Earthquake materials could be integrated into study resource. One of study resource that could be developed based on 21th century learning process was electronic book or e-book. The aim of this research was to rendering integrated physics e-book of earthquake material based on problem based learning to improve the responsiveness of students. This research used is a Quasi Experiment research. The population this research was the students of grade X MIA in SMAN 2 Ranah Pesisir which registered at he academic year of 2020/2021. The samples used is purpose sampling. This research instruments used is responsiveness competence through observation sheet, knowledge competence through pretest and posttest, skills competence through performance. The data of responsiveness an skill competence obtained were analyzed by using chart analysis and the data of the knowledge competence were analysis by using N-gain. Based on the results of the study it can be concluded that: 1) average responsiveness attitude of competence is very good categories, 2) N-gain of knowledge competence is high categories, and 3) average skill competence is very good categories. This shows that there are integrated Physics e-book of earthquake material based on problem based learning was valid, practical, and effective for increasing the students competencies, which includes competencies of responsiveness attitude, knowledge, and skill.

Pada saat pembelajaran akan dilaksanakan, hendaknya seorang tenaga pendidik yang profesional harus memahami karakteristik isi pesan pembelajaran yang akan disampaikan, agar tidak salah dalam memilih strategi pembelajarannya, interaksi pembelajaran, pengelolaan kelas, pemilihan bahan pembelajaran, dan media pembelajaran, serta alat evaluasi yang akan digunakan. Bahan pembelajaran dalam konteks pembelajaran merupakan salah satu komponen yang harus ada, karena mbahan pembelajran merupakan suatu komponen yang harus dikaji, dicermati, dipelajari dan dijadikan bahan materi yang akan dikuasai oleh siswa dan sekaligus dapat memberikan pedoman untuk mempelajarinya. Tanpa bahan pembelajaran maka pembelajaran tidak akan menghasilkan apa-apa. Bahan pembelajaran mempunyai peran yang sangat penting dalam kegiatan pembelajaran. Bahan pembelajaran dapat berperan sebagai bahan belajar mandiri, apabila bahan pembelajaran didesain secara lengkap. Bahan pembelajaran ini dilengkapi dengan tujuan pembelajaran atau kompetensi yang akan dicapai, materi pembelajaran yang diuraikan dalam kegiatan belajar, ilustrasi media, prosedur pembelajaran, latihan yang harus dikerjkan dilengkapi rambu jawaban, tes formatif dilengkapi dengan kunci jawaban, umpan balik, daftar pustaka.
