Pengembangan LAPD Berstrategi Mind Mapping untuk Meningkatkan Keterampilan Berpikir Kreatif pada Materi Atom dan Nanoteknologi

DEVELOPMENT OF STUDENT ACTIVITY SHEET (SAS) BY USING MIND MAPPING STRATEGIES TO IMPROVE CREATIVE THINKING SKILLS ON ATOMIC AND NANOTECHNOLOGY MATERIALS

Penelitian ini bertujuan untuk mendeksripsikan LAPD yang layak untuk meningkatkan keterampilan berpikir kreatif peserta didik pada materi atom dan nanoteknologi ditinjau dari validitas isi dan konstruk melalui hasil validitas oleh para ahli, kepraktisan melalui aktivitas peserta didik dan respon peserta didik terhadap LAPD serta keefektifan melalui peningkatan berpikir kreatif peserta didik. Jenis penelitian ini termasuk penelitian dan pengembangan. Model pengembangan yang diigunakan mengacu pada model 4-D namun hanya dibatasi pada tahap define, design, dan  develop. Kegiatan uji coba dilakukan pada 34 peserta didik kelas XE-3. Validasi dilakukan oleh validitor ahli dengan skor yang ditentukan berdasarkan nilai modus. Hasil penelitian menunjukkan kelayakan LAPD ditinjau dari validitas isi dan validitas konstruk yang mendapatkan modus 4 dan 5 pada setiap aspek dengan kategori valid dan sangat valid sehingga secara keseluruhan LAPD memperoleh modus ≥4 dan dinyatakan valid.  Hasil analisis kepraktisan dilihat dari angket respon peserta didik dan observasi aktivitas peserta didik. Persentase kepraktisan berdasarkan angket respon peserta didik dan observasi peserta didik diperoleh sebesar 92,01% dengan kategori sangat praktis. Sedangkan hasil observasi aktivitas peserta didik diperoleh aktivitas relevan pada pertemuan 1 sebesar 97,62% dan pertemuan 2 97,37%, . Dari kedua persentase tersebut diperoleh persentase aktivitas relevan peserta didik sebesar 97,5% sehingga dapat dikatakan LAPD yang dikembangkan sangat praktis. Hasil analisis keefektifan LAPD diukur berdasarkan peningkatan keterampilan berpikir kreatif peserta didik melalui pretest dan posttest mind mapping serta soal uraian keterampilan berpikir kreatif materi atom dan nanoteknologi dengan nilai N-gain yang diperoleh secara berurutan sebesar 0,73 dan 0,72 dengan kategori tinggi. Berdasarkan hasil validitas, kepraktisan dan keefektifan sehingga LAPD berstrategi mind mapping layak digunakan sebagai perangkat pembelajaran untuk meningkatkan keterampilan berpikir kreatif pada materi atom dan nanoteknologi.

This study aims to describe the feasibility of LAPD to improve students' creative thinking skills.. This type of research includes research and development. The development of the model used refers to the 4-D model but is only limited to the stages of determination, design, and development. Trial activities were carried out on 34 students of class XE-3. The feasibility of the developed SAS is guided by validity, practicality, and effectiveness. Validation was carried out by expert validators with scores determined based on the mode value. The results of the study showed the feasibility of the teaching module in terms of content validity and construct validity which obtained modes 4 and 5 in each aspect with valid and very valid categories so that overall the teaching module obtained a mode ≥4 and was declared valid. The results of the practicality analysis were seen from the student response questionnaire and observations of student activities. The percentage of practicality based on the student response questionnaire and student observations was obtained at 92.01% with a very practical category. Meanwhile, the observation results of student activities obtained relevant activities at meeting 1 of 97.62% and meeting 2 97.37%. From the three percentages obtained the percentage of relevant participant activities was increased by 97.5% so that it can be said that the SAS was developed very practically. The results of the analysis of the effectiveness of SAS were measured based on the increase in students' creative thinking skills through the pretest and posttest mind map as well as questions about understanding creative thinking skills on chemical bonding material with N-gain values obtained respectively of 0.73 and 0.72 with a high category. Based on the results of validity, practicality and effectiveness, the mind map strategy teaching module is suitable for use as a learning tool to improve creative thinking skills on atomic and nanotechnology materials.

Key words: SAS, mind mapping, creative thinking skills, atoms and nanotechnology
