DEVELOPMENT OF STUDENT WORKSHEET WITH MIND MAPPING ORIENTED USING iMindMap APPLICATION FOR ATOMIC STRUCTURE AND THE PERIODIC SYSTEM OF ELEMENTS TOPIC

Abstract

Tujuan dari penelitian ini adalah mengetahui kelayakan secara teoritis dan empiris Lembar Kerja Siswa (LKS) Berorientasi Peta Pikiran Menggunakan Aplikasi iMindMap Pada Materi Struktur Atom dan Sistem Periodik Unsur, serta untuk mengetahui hasil belajar siswa setelah menggunakan Lembar Kerja Siswa (LKS) berorientasi peta pikiran. Metode  penelitian yang digunakan adalah metode Research & Development (R & D) oleh Sugiyono (2011). Instrumen penelitian yang digunakan adalah lembar validasi Lembar Kerja Siswa (LKS), lembar obsevasi, angket respon siswa, dan lembar tes hasil belajar. Sumber data diperoleh dari dosen kimia dan guru kimia, serta 15 siswa SMA Kelas X. Berdasarkan hasil penelitian yang telah dianalisis, rata-rata persentase penilaian dosen kimia dan guru kimia terhadap kelayakan secara teoritis LKS berorientasi peta pikiran menggunakan aplikasi iMindMap sebesar 89,63%. Hasil analisis terhadap kelayakan secara empiris LKS berorientasi peta pikiran ditinjau dari penilaian observasi aktivitas siswa oleh pengamat sebesar 87,92% dan respon siswa terhadap kelayakan LKS berorientasi peta pikiran sebesar 92,74%. Selain itu, hasil penelitian menunjukkan peningkatan hasil belajar siswa setelah menggunakan LKS berorientasi peta pikiran menggunakan aplikasi iMindMap dengan persentase ketuntasan hasil belajar mencapai 80%.

The aims to this research is to know the feasibility of the theoretical and empirical Student Worksheet with Mind Mapping Oriented Using iMindMap Application for Atomic Structure And The Periodic System of Elements Topic, and also to know student mastery learning after using student worksheet mind mapping oriented, The research is using Research & Development (R&D) method  by Sugiyono (2011). The instruments of the research are using validation sheet of student worksheet, observation of student activity sheet, student questionnaire responses, and mastery learning test sheet. Sources of data have obtained from the chemistry lecturer, chemistry teacher, and also 15 of high school students on 10^th Grade. Based on the research that has been analyzed, the average percentage assessment theoretical validity of chemistry lecturer and chemistry teacher to the feasibility of student worksheet with mind mapping oriented using iMindMap application is confirmed at 89,63%. The analyze results to empirical feasibility of student worksheet with mind mapping oriented based average percentage of student activity observation by observers is 87,92% and the students response to the feasibility of student worksheet with mind mapping oriented by 92,74%. Beside that, the results show that there is an improvement in student mastery learning after using student worksheet with mind mapping oriented using iMindMap application with mastery learning completeness percentage of 80%.
