Pengembangan Lembar Aktivitas Peserta Didik untuk Meningkatkan Kemampuan Argumentasi pada Materi Faktor-Faktor yang Memengaruhi Laju Reaksi Melalui Model Pembelajaran Argument Driven Inquiry

Development of Student Worksheets to Improve Argumentation Skills on Factors Influencing Reaction Rate Material Through the Argument Driven Inquiry Learning Model

Penelitian ini membahas mengenai pengembangan lembar aktivitas peserta didik untuk  meningkatkan kemampuan argumentasi pada materi faktor faktor yang memengaruhi laju reaksi melalui model pembelajaran Argument Driven Inquiry. Tujuan utama penelitian ini adalah untuk mengetahui kelayakan lembar aktivitas peserta didik berdasarkan aspek validitas, efektivitas, dan kepraktisan. Penelitian ini menggunakan model ADDIE yang dibatasi hingga tahap pengembangan, khususnya sampai pilot implementation. Penelitian dilaksanakan di Prodi S-1 Pendidikan Kimia Unesa dengan pelaksanaan pilot implementation di SMAN 1 Surabaya. Sumber data yang digunakan yaitu data validitas LAPD, data hasil pretest dan postest peserta didik, data angket respon peserta didik, serta data obersevasi aktivitas peserta didik.  Validitas LAPD diukur menggunakan lembar validitas, efektivitas LAPD diukur melalui tes kemampuan argumentasi, respon peserta didik diukur melalui angket, dan aktivitas peserta didik diukur melalui lembar observasi. Hasil penelitian menunjukkan bahwa aspek validitas mendapat kriteria baik hingga sangat baik dengan modus skor antara 4 hingga 5. Berdasarkan aspek efektivitas, diketahui p hitung adalah 0,00, di mana nilai ini lebih kecil dari nilai signifikasi yaitu 0,05 sehingga disimpulkan bahwa H0 ditolak dan H1 diterima, yaitu terdapat peningkatan yang signifikan antara skor pretest dan posttest. Berdasarkan aspek kepraktisan, didapatkan persen kepraktisan dari angket respon peserta didik yaitu 83,3%-100% dengan kriteria sangat baik dan persen kepraktisan dari lembar observasi aktivitas peserta didik yaitu 80%-100% dengan kriteria baik hingga sangat baik.

This study discusses the development of student worksheets to improve argumentation skills on the material of factors that influence reaction rates through the Argument Driven Inquiry learning model. The main objective of this study is to determine the feasibility of student worksheets based on the aspects of validity, effectiveness, and practicality. This study utilises the ADDIE model, which is primarily limited to the development stage, particularly during the pilot implementation phase. The study was conducted at the Chemistry Education Study Program, Unesa, with a pilot implementation at SMAN 1 Surabaya. The data sources used were LAPD validity data, student pretest and posttest results, student response questionnaire data, and student activity observation data. LAPD validity was measured using a validity sheet, LAPD effectiveness was measured through an argumentation ability test, student responses were measured through a questionnaire, and student activities were measured through an observation sheet. The results of the study showed that the validity aspect received good to very good criteria with a score mode between 4 and 5. Based on the effectiveness aspect, it is known that the p-value is 0.00, which is smaller than the significance value of 0.05. Therefore, it is concluded that H0 is rejected and H1 is accepted, indicating a significant increase between the pretest and posttest scores. Based on the practicality aspect, the practicality percentage of the student response questionnaire was 83.3% to 100%, meeting very good criteria, and the practicality percentage of the student activity observation sheet was 80% to 100%, meeting good to very good criteria.
