The Effectiveness of The Animation Video Learning Earth’s Layer Media to Improve Students’ Concept Understanding

Science learning of the earth’s layers subject is not optimal. One of the factors causing the less optimal learning is the lack of media that support this subject. Students want a learning media that can motivate them to learn and also make it easier for them to understand the subject matter. This study aims to analyze the effectiveness of instructional video animation media on the earth’s layers subject in terms of the results of understanding the concepts of junior high school students. This study used a research design “One group pretest-posttest design”. The subjects of this study were 28 students of class VII-D SMP Negeri 3 Sidoarjo. The data collection technique used the test method. The conceptual understanding indicator used is to give examples, categorize, compare and explain. The results of this study are that the indicators give an example of obtaining an n-gain of 0.84 in the high category, the indicators categorizing obtaining an n-gain of 0.67 in the moderate category, the indicators compare getting an n-gain of 0.69 with the medium category and the indicator. explained that obtaining an n-gain of 0.68 in the medium category. The indicator compares getting the lowest posttest score and the indicator gives an example of getting the highest posttest score. So it can be concluded that the animated video media as a learning medium on earth layer material is very effective in increasing students’ understanding of concepts 0.69 in the medium category and the indicator explains that it gets an n-gain of 0.68 in the moderate category. The indicator compares getting the lowest posttest score and the indicator gives an example of getting the highest posttest score. So it can be concluded that the animated video media as a learning medium of earth’s layers subject is very effective in increasing students’ understanding of concepts 0.69 in the medium category and the indicator explains that it gets an n-gain of 0.68 in the moderate category. The indicator compares getting the lowest posttest score and the indicator gives an example of getting the highest posttest score. So it can be concluded that the animated video media as a learning medium of earth’s layers subject is very effective in increasing students’ understanding of concepts.
