Abstract

Miskonsepsi kimia adalah kesalahan dalam memahami konsep-konsep dasar seperti struktur atom, ikatan kimia, dan reaksi kimia. Miskonsepsi dipengaruhi oleh strategi pengajaran yang kurang menekankan pada rekonstruksi konseptual peserta didik. Upaya yang dapat dilakukan untuk mengatasi miskonsepsi adalah melalui pembelajaran remedial Conceptual Change. Pembelajaran remedial mudah dilaksanakan melalui Penelitian Tindakan Kelas (PTK). Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk mendampingi guru kimia di Kota dan Kabupaten Mojokerto dalam mengimplementasikan PTK sebagai upaya mengatasi miskonsepsi peserta didik. Pendekatan yang digunakan adalah pendampingan berkelanjutan melalui pelatihan, praktik penyusunan perangkat pembelajaran, serta implementasi PTK berbasis Conceptual Change. Kegiatan dilaksanakan sejak April hingga November 2025 dan melibatkan guru kimia anggota MGMP Kota dan Kabupaten Mojokerto. Tahapan kegiatan meliputi persiapan perangkat pelatihan, pendampingan penyusunan proposal PTK dan Lembar Kegiatan Peserta Didik berbasis Conceptual Change, pendampingan pelaksanaan PTK hingga dua siklus, serta evaluasi dan refleksi hasil kegiatan. Data dikumpulkan melalui tes diagnostik konsepsi, angket, observasi, dan analisis laporan PTK peserta. Hasil kegiatan menunjukkan peningkatan pemahaman guru terhadap miskonsepsi peserta didik, pemahaman mendalam dan penguasaan teknik PTK, mulai dari karakteristik, siklus pelaksanaan, hingga kemampuan merancang proposal PTK yang secara spesifik berfokus pada upaya reduksi miskonsepsi, dan respon positif dari guru sebagai peserta pelatihan. Berdasarkan hasil tersebut, dapat disimpulkan bahwa kegiatan PkM telah mencapai tujuan yang ditetapkan. Saran untuk pelaksanaan PkM tahun berikutnya adalah pelatihan penulisan artikel ilmiah sebagai hasil PTK untuk mereduksi miskonsepsi kimia peserta didik.

Abstract

This study aimed to determine the feasibility of student’s worksheet (LKM) for training students' argumentation skills in reaction rate material. The feasibility of LKM was reviewed in terms of validity, practicality, and effectiveness. The type of research used was Research and Development (R&D) with a 4D development model by Thiagarajan with three stages, namely definition, design, and development. A limited trial was conducted in class XI-5 at SMAN 1 Singgahan Tuban. The analysis of the feasibility of the LKM from the validity aspect, as seen from the content and construct, yielded a mode score of 5 in the highly valid category. The practicality aspect of the LKM was seen from the percentage of student response questionnaires of 98.07% and student activity observation sheets of 95.67%, which were classified as highly practical. The effectiveness aspect was analyzed based on the increase in pretest and posttest scores for argumentation skills and learning outcomes, reviewed through a paired sample t-test analysis. Both had a P-Value (1-tailed) of 0.000, so the P-Value (1-tailed) < 0.005, leading to the rejection of H0 and acceptance of H1. Therefore, it can be concluded that LKM is suitable for use as a learning medium to train students' argumentation skills in reaction rate material.

Abstract

This study was conducted to analyze the feasibility of PBL-based LAPD in developing critical thinking skills in Phase F of buffer solution material. The feasibility of LAPD was evaluated based on the aspects of validity, practicality, and effectiveness. The research design applied was Research and Development (R&D) with the 4D Thiagarajan development model, which includes definition, design, and development. Limited-scale testing was applied to grade XI students at Widya Darma High School in Surabaya. The feasibility analysis of LAPD in terms of content validity, construct validity, and graphic validity showed a mode score of 5, which is classified as very good. The practicality of the LAPD was proven by a student response rate of 90% and an activity observation result of 93.30%, thus classified as very practical. The effectiveness aspect was determined based on the pretest and posttest critical thinking scores. Testing with the paired t-test method obtained a right-hand p-value of 0.000 (<0.05), so the alternative hypothesis H1 was accepted and H0 was rejected. This improvement was supported by a critical thinking N-gain value of 0.77 in the high category, as well as student learning outcomes of 87.5, which had reached mastery. The analysis results indicate that PBL-oriented LAPD is feasible to be applied to train critical thinking on buffer solution material.
