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.
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.
