摘要:This research aims to find information about the improvement of mathematics achievement of grade five student
through guided discovery learning. This research method is classroom action research using Kemmis and Taggart
model consists of three cycles. Data used in this study is learning process and learning results. Learning process
data is obtained by check list and is descriptive analyzed. Learning results data is obtained by conducting test and
is analyzed by simple statistics. The result shows that student's ability of observation, discussion and knowledge
acquisition are improved with guided discovery learning. Hence, guided discovery learning improves students’
mathematics learning outcomes.
