The Improvement Efforts on Physics Activity and Results of Learning Using Practicum

This study aims to increase physics activity learning outcomes with practical methods in class XI IPA1. The study was conducted in two cycles, consisting of: planning, implementation, analysis, reflection. The first cycle is obtained, the students' activity consider the teacher's explanation 57.14%, using the laboratory equipment of 22.86%. cooperation between students in the group 28.57%, asking questions11.43%, answering teachers questions 45.71%, expressed ideas 8.57%, draw conclusions 42.85%. make reporting 51.43%, punctuality 42.86%. Learning outcomes mean 66.60, highs 79.00, lows 53.00, classical completeness 57.14%. In the second cycle of the student activity increased to 94.28%. Using laboratory equipment 85.71%. cooperation between of students in the group 71.43%, asking the question 40%, answered questions teachers 82.86%, expressed the idea 28.57%, summed 80.00%. make reporting 97.15%, punctuality 85.71%, and learning outcomes mean of 77.80, 89.00 highs, lows 63.00 88.57% classical completeness. Penelitian ini bertujuan untuk meningkatkan aktifitas hasil belajar fisika dengan metode praktikum pada siswa kelas XI IPA1. Penelitian dilakukan dua siklus, terdiri dari: perencanaan, pelaksanaan, analisis, refleksi. Siklus pertama diperoleh, aktifitas siswa memperhatikan penjelasan guru 57,14%, menggunakan alat-alat laboratorium 22,86 %. kerjasama antara siswa dalam kelompok 28,57 %, mengajukan pertanyaan 11,43%, menjawab pertanyaan guru 45,71%, menyatakan ide 8,57 %, menarik kesimpulan 42,85%. membuat pelaporan 51,43 %, ketepatan waktu 42,86%. Hasil belajar rerata 66,60, tertinggi 79,00, terendah 53,00, ketuntasan klasikal 57,14%. Pada siklus kedua aktivitas siswa meningkat menjadi 94,28%, Menggunakan alat-alat laboratorium 85,71%. kerjasama antara siswa dalam kelompok 71,43%, mengajukan pertanyaan 40 % menjawab pertanyaan guru 82,86%, menyatakan ide 28,57%, menyimpulkan 80,00%. membuat pelaporan 97,15%, ketepatan waktu 85,71%, serta hasil belajar rerata 77,80, tertinggi 89,00, terendah 63,00 ketuntasan klasikal 88,57%.
