PENGEMBANGAN SOFTWARE MISTION UNTUK MENDETEKSI DAN MEREDUKSI MISKONSEPSI PESERTA DIDIK DENGAN STRATEGI CONCEPTUAL CHANGE TEXT PADA MATERI STOIKIOMETRI

DEVELOPMENT OF MISTION SOFTWARE TO DETECT AND REDUCE STUDENTS' MISCONCEPTION WITH CONCEPTUAL CHANGE TEXT STRATEGY ON STOICHIOMETRY MATERIALS

Miskonsepsi sering terjadi, terutama pada materi kimia yang sarat akan konsep abstrak. Stoikiometri merupakan materi yang sulit karena memiliki banyak konsep abstrak. Tujuan penelitian ini adalah untuk mengetahui kelayakan pengembangan software mistion untuk mendeteksi dan mereduksi miskonsepsi pada materi stoikiometri dengan strategi conceptual change text. Penelitian ini dilakukan dengan menggunakan metode Research and Development (R&D) dengan subjek penelitian 15 siswa SMAN 1 Gedangan. Software dikembangkan menggunakan Adobe Flash CS 6 dengan action script 3.0. Kelayakan perangkat lunak dilihat dari aspek validitas berdasarkan lembar validasi, kepraktisan berdasarkan angket respon peserta didik yang didukung lembar observasi aktivitas peserta didik, dan keefektifan berdasarkan hasil pergeseran miskonsepsi. Hasil analisis data menunjukkan bahwa 1) Software sangat valid dengan rata-rata hasil validasi isi 93,52%, dan validasi konstruk 91,82%. 2) Software sangat praktis, dengan rata-rata hasil angket respon siswa viii sebesar 95,28% dan didukung oleh rata-rata hasil observasi siswa sebesar 85%, 3) Software efektif dengan hasil rata-rata pergeseran miskonsepsi untuk sub-konsep hukum dasar kimia sebesar 77,27% dengan kategori efektif, sub-konsep persamaan reaksi sebesar 85,05% dengan kategori sangat efektif, dan sub-konsep mol adalah 73,72 % dengan kategori efektif.

Misconceptions often occur, especially in chemical materials, which are full of abstract concepts. Stoichiometry is a problematic material because it has many abstract concepts. The purpose of this study was to determine the feasibility of developing mistion software to detect and reduce misconceptions in stoichiometric material with a conceptual change text strategy. This research was conducted using the Research and Development (R&D) method with 15 students of SMAN 1 Gedangan as research subjects. Software is developed using Adobe Flash CS 6 with action script 3.0. The software's feasibility is viewed from the validity aspect based on validation sheets, practicality based on student response questionnaires supported by student activity observation sheets, and effectiveness based on the results of misconceptions shift. The data analysis results show that 1) the software is very valid with the average result of content validation is 93.52%, and the construct validation is 91.82%. 2) The software is very practical, with an average result of student response questionnaires is 95.28% and supported by an average result of student observations is 85%. 3) Software is effective with the average result of misconception shift for sub-concept basic chemical law x is 77.27% with effective category, sub-concept of reaction equation is 85.05% with very effective category, and sub-concept of mole is 73,72% with effective category.
