Penelitian bertujuan mendeskripsikan kualitas LKPD elektonik pada konsep plantae berbasis keterampilan berpikir kritis jenjang SMA yang valid, praktis, dan efektif. Penelitian ini dilakukan dengan metode desain Evaluasi Formatif Tessmer, melalui langkah pengembangan 1) Self evaluation, 2) Expert Review, 3) One-to-one evaluation, dan 4) Small group evaluation. Subjek uji validitas adalah tiga orang ahli, subjek uji perorangan adalah tiga orang peserta didik kelas X SMA, subjek kelompok kecil adalah empat orang peserta didik kelas X SMA.
