Abstract

Information obtained from the results of interviews with chemistry teachers that there is no LKPD that uses the problem based learning model. Based on the summative value of students on the material of basic chemical laws, it can be concluded that students' understanding of the material of basic chemical laws is still low. This study aims to develop and analyze the validity and practicality of teaching materials in the form of LKPD basic chemical laws based on problem based learning phase E of SMA. The type of research conducted is Educational Design Research (EDR) with the Plomp model. The data obtained are processed using the Aiken's V formula. The study was conducted at the Department of Chemistry, FMIPA UNP and SMA Pembangunan Laboratorium UNP. The validation results show that LKPD has a validity value of 0.90 and a practicality value for teachers of 93.75% and students of 88.6%. The results of the study indicate that the LKPD basic chemical laws based on problem based learning that was developed is valid and practical.

Abstract

Pembelajaran kimia di SMA kerap menjadi tantangan karena sifatnya yang abstrak, khususnya pada materi rumus kimia, tata nama, dan persamaan reaksi. Berdasarkan observasi di SMAN 11 Padang, banyak peserta didik belum mencapai ketuntasan belajar. Penelitian ini bertujuan menganalisis pemahaman konsep dan sikap peserta didik serta hubungan antara keduanya. Metode yang digunakan adalah deskriptif kuantitatif denngan teknik simple random sampling pada peserta didik kelas X Fase E. Data dikumpulkan melalui tes diagnostik Three-Tier dan angket sikap berbasis skala Likert yang dimodifikasi dari CLASS. Instrumen berupa tes diagnostik yang telah divalidasi oleh ahli dan uji reliabilitas, daya beda, serta indeks kesukaran sebelum digunakan pada tiga kelas sampel. Sementara itu, Instrumen angket sikap CLASS telah terbukti valid dan reliabel sehingga tidak perlu dilakukan pengujian ulang. Hasil menunjukkan pemahaman konsep tergolong rendah 21,46%, dengan tingkat miskonsepsi 67,38% dan tidak paham konsep 10,70%. Sebaliknya, sikap peserta didik terhadap pembelajaran kimia tergolong baik. Uji korelasi Pearson menunjukkan hubungan positif yang lemah antara sikap dan pemahaman konsep. Temuan ini menegaskan perlunya strategi pembelajaran yang lebih efektif untuk meningkatkan pemahaman konseptual.
