The Development of Learning Devices with the Etnoid (Ethnoscience Android) Assisted Guided Inquiry Model on Vibration and Wave Materials

This research was conducted in two stages; the preparation stage which was aimed to develop the device, followed by the implementation stage of learning in the classroom using the pretest-posttest design. The validation test consisted of media validation tests by media expert lecturers from the chemistry department and one junior high school science teacher, and the material validation test by material experts from the Science Study Program lecturers. The learning phase was carried out by involving 30 eighth grade students at Junior High School who had taken the material of vibration and waves. The results of the development were in the form of learning tools with Etnoid-assisted guided inquiry model. The validity score was 93.88%, indicating the very valid category, practicality score was 86.70%, of very practical categories, while effectiveness was 0.703, of high category, meaning that information was very effective to use in learning. Based on results, it could be generally concluded that the learning device developed with Etnoid-assisted guided inquiry model met very
