Learning media is an important learning tool to consider in the learning process. The presence of learning media can make learning more interesting and active, so that the use of media can help increase student achievement and learning motivation. The presence of learning media in citizenship learning content is considered very important to reduce the verbality of citizenship learning material. The aim of this research is to develop wordwall-based citizenship learninglearning media that can be used by teachers to transfer material and carry out learning evaluations. The type of research used in this research is development research (Research and Development). Research and development is research that aims to produce a product that comes from research and testing the product that has been developed. The development research model is the ADDIE model which consists of five stages of development research. The five stages are analysis, design, development, implementation and evaluation. In this research, the development stage will be discussed up to the ADD stage. The subjects in this research were media experts, material experts, and three 6th grade elementary school students to test the level of appropriateness of the media. Based on the validation test, it can be seen that through the two stages of validation by experts, the wordwall media was declared very suitable for use in learning. This is because wordwall media can have a positive influence on the classroom climate and student learning outcomes.

Education is considered crucial in improving the quality of human resources, especially through the process of personal formation through education. Law Number 20 of 2003 concerning the national education system emphasizes the importance of a learning atmosphere and an active learning process. Teachers, especially in science learning, face challenges such as low motivation and lack of interest in the material.This research uses a quasi-experimental method to evaluate the effect of using video-based learning media on elementary school students' knowledge, especially in classifying animals. The research results show that video media is effective in increasing students' learning interest and motivation, facilitating understanding of abstract science concepts, and optimizing cognitive learning outcomes.It was found that learning with video media creates a fun, active and motivating learning atmosphere, contributing to the success of science teaching in fourth grade elementary school. The implications of this research indicate that the use of video media can be an effective solution in improving science learning at the elementary level, building students' interest in learning, and supporting their cognitive development.

This assessment aims to assess the role of learning planning on the quality of educators in teaching and learning activities, the obstacles faced by teachers in carrying out learning planning at UPT SDN 060909. This research uses qualitative methods with a descriptive approach. The research subjects were all homeroom teachers at UPT SDN 060909 Medan Denai. The obstacle faced by teachers is that real teachers cannot guarantee that all students will be interested because there are also students who do not participate, for example when using the conversation method, students become calmer and still do not answer anything. This discussion method is very important to stimulate student activity. However, teachers always evaluate this to continue to improve the quality of educators so that these plans can be used as reference material for further development. From the research results, it was found that learning planning is very important in teaching activities, because learning planning can be a reference for a teacher to carry out learning in the classroom.
