The design of laboratory activities is used in practicum activities in schools to develop scientific process skills. This study provides an overview of the design of laboratory activities used in schools. The research method used is descriptive qualitative with a research sample of six practical worksheets selected by purposive sampling technique. The research instruments used in the study were conceptual analysis, competency analysis, practical analysis and knowledge construction analysis based on the Vee Diagram scoring table adapted from Novak & Gowin (1984). The results showed that all DKL met the minimum standards of curriculum competency standards in force. Whereas for competency analysis, most of the laboratory activity designs used have not developed a high level cognitive level and have not trained the scientific method skills needed by students, in the practical aspects of tools and materials can be easily obtained, but for the structure of the work steps there are unstructured ones. The results of the analysis of knowledge construction using instruments from Novak & Gowin (1984) show that most procedural steps can be done but are less relevant to the knowledge reconstruction process or do not lead to the formation of knowledge claims in linking object events (observed facts) with the knowledge they already have. .Reconstruction made base the results of analysis DKL.
Desain kegiatan laboratorium digunakan dalam kegiatan praktikum di Sekolah untuk mengembangkan keterampilan proses ilmiah. Penelitian ini memberikan gambaran desain kegiatan laboratorium yang digunakan di Sekolah. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan sampel penelitian berjumlah enam lembar kerja praktikum yang dipilih dengan Teknik purposive sampling. Instrumen penelitian yang digunakan dalam penelitian yaitu analisis konseptual, analisis kompetensi, analisis praktikual dan analisis konstruksi pengetahuan berdasarkan tabel penskoran Diagram Vee yang diadaptasi dari Novak & Gowin (1984). Hasil penelitian menunjukkan bahwa seluruh Desain Kegiatan Laboratorium (DKL) memenuhi standar minimum standar kompetensi kurikulum yang berlaku. Sedangkan untuk analisis kompetensi sebagian besar desain kegiatan laboratorium yang digunakan belum mengembangkan level kognitif tingkat tinggi dan belum melatihkan kemampuan metode ilmiah yang dibutuhkan oleh siswa, pada aspek praktikal alat dan bahan dapat dengan mudah diperoleh namun untuk struktur langkah kerja terdapat yang tidak terstruktur. Pada hasil analisis konstruksi pengetahuan menunjukkan sebagian besar procedural dapat dikerjakan namun kurang relevan dengan proses rekonstruksi pengetahuan. Rekonstruksi DKL dibuat berdasarkan hasil analisis DKL.Â
