Abstract

This research is a classroom action research (CAR) which aims to improve students' biology learning outcomes
through the Problem Based Learning model. The research was carried out in three cycles consisting of four
activities, namely: planning, implementing actions, observing and reflecting. Each cycle was carried out for one
meeting. Data collection techniques in this study were observation and tests. The data collection instruments used
were observation sheets to collect data on student activity in the learning process and multiple choice questions
to collect data related to learning outcomes. The data analysis technique is descriptive quantitative.
Based on the results of the research analysis, it was found that the percentage of student evaluation scores who
completed the KKM increased in each cycle, namely in the first cycle which was completed by 31.25%, the second
cycle by 50%, and in the third cycle it increased to 87.5%. So the researcher can suggest that the problem-based
learning model can be an alternative learning model that is applied to biology subjects to improve student learning
outcomes.
