Hasil rekonstruksi diharapkan sebagai sumber alternatif desain kegiatan laboratorium yang dapat digunakan oleh guru dan siswa sebagai pedoman dalam kegiatan praktikum pada materi sistem indera.

Namun belum banyak kegiatan praktikum biologi yang mendukung pada kemampuan literasi kuantitatif siswa. Penelitian ini bertujuan untuk memberi gambaran mengenai kualitas desain kegiatan laboratorium (DKL) materi respirasi anaerob yang tersedia di lapangan serta mengembangkan DKL alternatif yang dapat memfasilitasi keterampilan laiterasi kuantitatif siswa. Metode penelitian ini adalah deskriptif dengan menggunakan pendekatan ANBUCOR (Analisis, Buat, Coba, dan Rekonstruksi). Tahapan penelitian meliputi analisis DKL lapangan, pembuatan DKL alternatif, uji coba, dan rekonstruksi. Instrumen penelitian berupa rubrik penilaian dan catatan lapangan. Hasil analisis terhadap DKL yang terdapat di lapangan menunjukan bahwa pada umumnya DKL telah relevan dengan tuntutan kurikulum namun terdapat kelemahan pada aspek kompetensi yaitu pada indikator interpretasi dan representasi data. Hasil pengembangan diperoleh DKL alternati...

The design can stimulate the formation of a concept that has previously been obtained. This study aims to analyze several laboratory activity designs, then conduct trials and reconstruct Practicum Activity Design which refers to the 2013 curriculum. The research method used is descriptive quantitative. The sample used in this study as many as nine Practicum Activity Design cladograms selected using purposive sampling technique. The research instrument used is the analysis section relevance, competence, construction of knowledge and practical analysis that has been in judgment by experts. The results showed that the relevance aspect already refers to KD, namely the preparation of a cladogram based on the principle of classification. But in some other aspects it has drawbacks. These deficiencies include unclear tools and materials, unclear working procedures, difficult data interpretation processes. So ...
