Pengembangan Android Mobile Learning CHEMDIC untuk Mencegah Terjadinya Miskonsepsi Peserta Didik pada Materi Sistem Periodik Unsur

Development of Android CHEMDIC Mobile Learning to Prevent Student Misconceptions on Periodic System of Elements Material 

Penelitian ini bertujuan untuk mengembangkan android mobile learning yang layak digunakan dalam pembelajaran untuk mencegah terjadinya miskonsepsi peserta didik pada materi sistem periodik unsur. Aspek kelayakan ditinjau dari tiga indikator yaitu (1) validitas mobile learning yang mencakup validitas isi dan validitas konstruk berdasarkan hasil penilaian oleh validator, (2) kepraktisan mobile learning yang ditinjau berdasarkan hasil angket respon dan hasil observasi aktivitas peserta didik, (3) keefektifan mobile learning yang ditinjau berdasarkan hasil pretest dan posttest dengan melihat pergeseran konsepsi peserta didik dari yang awalnya tidak paham konsep (TPK) menjadi paham konsep (PK). Penelitian ini merupakan penelitian pengembangan dengan metode Research and Development (R&D) menurut Thiagarajan (1974) dengan subjek penelitian 15 peserta didik SMAN 1 Krian Sidoarjo yang telah memperoleh materi sistem periodik unsur sebelum uji coba. Hasil penelitian yang diperoleh menunjukkan bahwa mobile learning layak digunakan sebagai multimedia dalam pembelajaran dan untuk mencegah terjadinya miskonsepsi peserta didik pada materi sistem periodik unsur. Hasil yang diperoleh antara lain (1) Skor modus validitas isi sebesar 5 dengan kategori sangat valid serta skor modus validitas konstruk sebesar 4 dengan kategori valid, (2) persentase rata-rata angket respon peserta didik memperoleh skor sebesar 96% dengan kategori sangat praktis dan hasil observasi aktivitas peserta didik memperoleh skor sebesar 95,81% dengan kategori sangat mendukung hasil angket respon peserta didik, (3) persentase rata-rata hasil pergeseran konsepsi peserta didik dari tidak paham konsep (TPK) menjadi paham konsep (PK) memperoleh skor sebesar 95,89% sehingga termasuk kategori sangat efektif.

This research aims to develop android mobile learning that is feasible to be used in learning to prevent students' misconceptions on the material of the periodic system of elements. The feasibility aspect is reviewed from three indicators, namely (1) the validity of mobile learning which includes the validity of the content and the validity of the construct based on the results of the assessment by the validator, (2) the practicality of mobile learning which is reviewed based on the results of the response questionnaire and the results of observation of student activities, (3) the effectiveness of mobile learning which is reviewed based on the results of the pretest and posttest by looking at the shift in students' conception from those who initially did not understand the concept (DU) to understand the concept (U). This research is a development research with the Research and Development (R&D) method according to Thiagarajan (1974) with the research subjects of 15 students of SMAN 1 Krian Sidoarjo who have obtained periodic system material before the trial. The research results obtained show that mobile learning is suitable to be used as multimedia in learning and to prevent students' misconceptions in the material on the periodic system of elements. The results obtained included (1) the content validity mode score is 5 with a very valid category and the construct validity mode score is 4 with a valid category, (2) the average percentage of student response questionnaires obtained a score of 96% with a very practical category and the results of student activity observation obtained a score of 95.81% with a category that strongly supported the results of the student response questionnaire, (3) the average percentage of students' conception shift from didn’t understand the concept (DU) to understand the concept (U) obtained a score of 95.89% so that it was included in the very effective category.
