The objective of the present study was to analyze the correlation between the representation of similar experience and the generation of scientific hypothesis of biology teachers on the swallowtail butterfly task. For this purpose, 38 biology teachers were sampled, and their teaching experience was 7.8 years on the average. ‘The task of butterfly’ including ultimate causes was selected as a scientific hypothesis formulation task. The biology teachers represented 2.9 similar experiences on the average, and classified them into five related categories. We developed an equation for calculating the similar experience representation quotient by defining similar experiences’ degree of likeness. Calculated by the equation, the biology teachers’ similar experience quotient (SEQ) was 10.16±9.50 on the average. A total of 79 scientific hypotheses and 2.1 per teacher were generated. The mean hypothesis generation quotient (HQ) was 23.53±16.51. The Pearson correlation coefficient (r) between SEQ and HQ was 0.76 (p<0.01). The correlation coefficient suggests a strong positive correlation between the two quotients. That is, it means that the representation of similar experiences plays a very important role in hypothesis generation process. Therefore, the results of this study demonstrate that, in hypothesis generation learning, it is a very effective teaching‐learning strategy to present similar experiences in order of relevancy.
