Abstract

The purpose of this study was to examine a method of instruction that might help the learner discover a hidden regularity in a phenomenon. We decided to try visualization of the phenomenon as an instruction method applied during observation possibly leading to this discovery. To verify the effectiveness of the method, a class studying phyllotaxis was divided into two groups. For the experimental group, we decided to write numbers sequentially on the leaves, starting from the lowest leaf.<br>The result of the observation shows that the experimental group had more students who noticed that leaves were arranged on the stem in a spiral pattern than the control group. In addition, discussions about the fact that leaves were arranged in a spiral were more frequent in the experimental group than in the control group. This suggests that devising a visualization of the phenomenon is an effective instruction method to help learners discover regularity.
