| Metode Pembelajaran | KBL (Knowledge Based Learning): Mahasiswa diberi bahan kajian yang diharapkan dapat meningkatkan pengetahuannya, melalui kegiatan seperti ceramah, menonton video. Tepat untuk kuliah yang CPMK-nya mementingkan kognitif.
PBL (Problem Based Learning): Mahasiswa dihadapkan pada suatu masalah, dan mencari solusinya dengan mengaplikasikan BK. Tepat untuk kuliah yang CPL-nya mengandung pemecahan masalah (problem solving).
CBL (Case Based Learning): Mahasiswa dihadapkan pada kondisi nyata di Masyarakat / dunia, dan menanggapinya dengan memilih solusi terbaik menggunakan BK. Perlu digunakan untuk kuliah yang CPL-nya mementingkan pengambilan keputusan secara subyektif (etika, profesinalisme, dll.). | KBL (Knowledge Based Learning): Students are given study materials that are expected to improve their knowledge, through activities such as lectures, watching videos. Suitable for lectures whose course learning objective emphasizes cognitive.
PBL (Problem Based Learning): Students are faced with a problem, and find a solution by applying study materials. Suitable for lectures whose learning outcomes contains problem solving.
CBL (Case Based Learning): Students are faced with real conditions in society / the world, and respond to them by choosing the best solution using study materials. Needs to be used for lectures whose learning outcomes emphasizes subjective decision making (ethics, professionalism, etc.). |
