Development of Vidio Explainer learning media based on case method and network in the Mathematics Economics course to improve students' understanding of concepts

Technology continues to develop into the world of education, especially universities. The development of the world of digital technology is accelerating, even its development is faster than the world of education itself. This era is characterized by the use of technology to process data, including processing, obtaining, compiling, storing, manipulating data in various ways to produce quality, relevant and accurate things. The acceleration of technological progress has also given birth to new policies in the world of higher education, including Universitas Negeri Medan which has issued a decree through the Rector's Decree No. 000119/UN33/KP/2022 which states that learning in Universitas Negeri Medan environment in the Even Semester 2021/2022 is carried out through Hybrid Learning. The characteristics of Hybrid learning include integrating technology in learning. Technology integration in learning is utilizing a tool in developing and using learning tools, such as technology integration in learning media. One of them is the explainer video learning media. The objectives of this study are 1) Developing Case Method Learning Media Vidio Explainer economic mathematics course, 2) Describing the Validity of Case Method Learning Media Vidio Explainer economic mathematics course 3) Describing the practicality and effectiveness of Case Method Learning Media Vidio Explainer economic mathematics course.
