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

Critical thinking is the ability to analyze and find out the truth of the information obtained in order to determine the right decision. The purpose of this study was to determine the critical level of class VIII students at SMP Negeri 2 Bungkal, especially on the material of the human excretory system. Type of this research is descriptive qualitative. The subjects used were students of class VIII A SMP Negeri 2 Bungkal, Ponorogo who collected 30 students using purposive sampling technique. Data collection techniques consist of interviews and tests. The research instrument consisted of a teacher interview sheet and a critical thinking question instrument that had been validated by expert lecturers. The data analysis technique used is descriptive analysis technique. The results showed that in the aspect of interpreting the average score was 34.66 (very low), analyzing 38.66 (low), evaluate 55.33 (enough), concluding 29.99 (very low), explaining 58.66 (enough). So that overall students' critical thinking is included in the low category with an average value of 43.46. This research is important because it can be used as input for teachers to design learning using appropriate models and approaches so that they can develop and improve students' critical thinking

Masa pandemi Covid-19 pada saat ini sangat bergantung pada Kemajuan teknologi. Pembelajaran secara online menyebabkan suatu masalah kecemasan, ketidaksetaraan antara anak-anak karena akses, beresiko kecanduan internet, tidak memiliki disiplin belajar yang diperlukan dalam pendidikan individu Sehingga pada penelitian ini bertujuan untuk menganalisis hasil belajar dan respon siswa setelah pembelajaran menggunakan media padlet berbantuan phet simulation. Metode penelitian yang digunakan adalah quasi eksperimental desain dengan desain penelitian one group pretest and posttest. Subjek penelitian adalah siswa kelas IX. Teknik analysis data menggunakan uji paired sample t test . Hasil uji normalitas pretest dan posttest di peroleh nilai hasil pretest sebesar 0,053 dan hasil postest 0,056. Sehingga dapat disimpulkan bahwa data terdistribusi normal. Hasil uji hipotesis menunjukkan bahwa nilai siginifikansi 2 arah yaitu 0,000<0,05 yang menunjukkan bahwa H0 ditolak dan H1 diterima. Berdasarkan hasil penelitian diperoleh bahwa hasil belajar siswa antara tes pretest dan tes posttest setelah menggunkaan media padlet berbantuan phet simulation meningkat adapun respon siswa menyatakan baik terhadap penggunaaan media padlet berbantuan phet simulation ketika pembelajaran online. Jadi penggunaan media padlet berbantuan phet simulation cocok digunakan ketika proses pembelajaran online.
