Inquiry Based Lesson Study to Improve Students' Activity in Learning Biology

摘要

This lesson study was aimed at improving students' activity through inquiry learning model on General Biology subject. It was conducted in odd semester of academic year 2012/2013, for the first semester students at Class A on General Biology subject, Department of Biology Education, Universitas Muhammadiyah Purwokerto. The subjects of this lesson study were students taking General Biology subject from class A; they were 30 persons consisting of 23 female students, and 7 male students. The learning process included four basic actions correlated and continued each other in each cycle; the actions were: (1) planning, (2) acting, (3) observing, and (4) reflecting.
