Learning has now gradually recovered from the effects of the COVID-19 pandemic with the start of limited face-to-face learning. This makes educators need to innovate so that students still have independent learning. Online learning that is less than optimal causes students to be too passive when learning offline. The use of technology, the selection of interesting learning models, and media according to the characteristics of the material, especially abstract material, are still needed to answer the challenges of 21st-century learning. The use of technology and the development of students' learning independence is very important to face real life and make learning more effective. The purpose of this study is to analyze the learning independence of students through the implementation of LKPD discovery learning assisted by augmented reality. This research is descriptive qualitative research with 28 students of class VIII at SMP N 2 Karangnongko. The data collection technique used a student learning independence questionnaire, which was triangulated with learning observation sheets and interviews with science teachers. The data analysis technique according to Miles Huberman (1992) goes through three steps, namely data reduction, data displaying, and conclusion drawing/verification. The results of the learning independence questionnaire were analyzed using the percentage technique. Based on the learning independence questionnaire data, the average percentage is 70% in the medium category

Technology-based mobile can be used as an experimental tool is Phypox. This study aims to report using a combination of Suling and Phypox in experiment activities. The designed activity aims to engage students in critical thinking. The instrument for measuring critical thinking consists of five questions based on the critical thinking aspect: interpretation, analysis, evaluation, inference, and explanation. The study used a one-group pre-and post-test design on 32 8th-grade students at one of the junior high schools in West Java Province, Indonesia. The study procedure is a pre-test, discussion of Suling’s concepts, introduction to Phypox application, experiment activity, presentation, and post-test. Data analysis uses the normalized gain to compare the pre-and post-test. Experiment activities help students to understand frequency, open organ pipes concepts, and investigate the speed of sound produced by Suling. The study found a significant change in the pre-and post-test scores of students after experimenting, so it could be interpreted that the experimental activities using Suling and Phypox affected critical-thinking students.
