Upaya Peningkatan Aktivitas Belajar Melalui Penerapan Model Discovery Learning pada Mata Pelajaran Biologi di Kelas XI IPA2 SMA Pembangunan Laboratorium Universitas Negeri Padang

Abstract

Classroom action research has been carried out to find out the improvement of student learning activities in biology subjects during the learning process by applying the Discovery Learning model in the XI IPA2 Senior High School class. The background of this study was due to the low student learning activities observed at the initial observation. The design of this classroom action research uses was the Kemmis and McTaggart model, which consists of four steps, namely: plan, action, observing, and reflect. The lesson material presented during cycle 1 is the structure and function of cells, and in cycle 2 are various bioprocesses in cells. The steps of the Discovery Learning model that are carried out are as follows: (1) giving stimulus (stimulation), (2) identifying problems (problem statements), (3) data collection (data collection), (4) processing data (data processing) , and (5) verify. The subjects of this study were students of class XI IPA2 SMA Pembangunan Laboratorium Universitas Negeri Padang, which numbered 30 people. The study was conducted in the odd semester of the 2018/2019 academic year. Students' learning activities observed were: (1) paying attention to the teacher's explanation, (2) actively participating in the work on LKPD, (3) asking questions to the teacher/friend, (4) answering teacher/friend questions, (5) disturbing friends or doing other work. The data obtained were analyzed using percentage techniques. The percentage of learning activities obtained is then concluded by referring to the criteria proposed by Arikunto (2006). The results of this study revealed that the application of the Discovery Learning model on biology subjects in class XI IPA2 SMA Pembangunan Laboratorium Universitas Negeri Padang could increase students' positive learning activities and reduce negative activity.
