The impact of the COVID-19 pandemic has affected various fields of life, including education, resulting in changes to the learning system. The purpose of this research is to analyze the difficulties experienced by physics teachers during learning online. The sample in this study was 8 physics teachers with the criteria of 2 male teachers and 6 female teachers with the specifications of 6 senior teachers and 2 junior teachers. The research method used a quantitative approac h with an instrument in the form of a questionnaire to analyze the difficulties of physics teachers in online learning, the analytical model used is interactive analysis. The results of this study illustrate that in general physics teachers in Banda Aceh have difficulty in teaching online. The most dominant difficulties are the lack of motivation and interest of students, student participation, and the difficulty of conveying abstract physics concepts. It is hoped that further research can examine the strategies that can be offered to physics teachers in online learning.

The low scientific literacy of Indonesian students attracts the attention of Indonesian education practitioners to continue researching the right solution to overcome it. With the help of multi-representation interactive multimedia, this research facilitated students to learn actively and independently. The aim of this research was to develop multi representation-based interactive multimedia (MRIM) to improve students' scientific literacy skills. The research method is research and development with 4D model (define, design, develop, and disseminate), and data analysis using Paired t-test. The define stage for problem identification and analyzing needs, we involved a sample of 30 students from 8th grade and 2 science teachers. At the design stage, a multimedia framework and scientific literacy instruments were created. In the develop stage, multimedia was tested on 1 lecturer as a reviewer, and 3 teachers, and then the media was tested on a small group, consisted of 7 students of 7th grade of SMPQT Al-Hamidiyah with random selection. And at the disseminate stage, all data that has been processed is then written in the form of articles which will then be published. The results of the expert judgment test stated that the multimedia is feasible to use, while the small group test results showed that this multimedia can improve students' scientific literacy skills with a significance value of 0.000 <0.05 (based on the results of the paired t-test). In conclusion, this interactive multimedia is very suitable for use in learning and can improve students' scientific literacy skills

Laboratories are an important part of physics learning activities in schools. However, learning activities in MAN 3 Banda Aceh still rarely use laboratory facilities. It is important to do research related to the use of laboratories in physics lessons. This study aims to determine the impact of laboratory use in achieving physics learning outcomes in MAN 3 Banda Aceh. This study uses a quantitative approach with the method used, namely the experimental method by comparing between experimental classes taught using laboratories and control classes that are not taught to use laboratories after being treated. The population in this study were all students of class X MIA in MAN 3 Banda Aceh. The research sample was selected by purposive sampling, which consisted of class X MIA 1 as the experimental class and class X MIA 2 as the control class. The research data consisted of pre-test and post-test. Then the data of this study were analyzed using t-test statistics. Results The study found that the pre-test value was normally distributed and homogeneous. Then based on the t-test obtained, (4.118) ≥ (2.009). It can be concluded that the results of physics learning using laboratories are better than those that do not use laboratories in students of MAN 3 Banda Aceh.
