The aim of this research is to investigate the learning effect of the fifth grade students after the biochar teaching activity. The Researcher directed an unequal post-test control group designed for two classes in a medium-size elementary school in Chiayi County. Class A is the experimental group and class B is the control group. Based on teaching objectives and research purposes, the researcher designed the course according to the students’ biochar learning goal and of their applying POE into biochar teaching. The data sources include before and after measured analysis, the POE learning sheet, and two-tier diagnostic test data. According to the analysis data, the researcher comes to the following conclusions: A. Compared to traditional didactic teaching, POE teaching establishes the concept of biochar more among the high-score students studied in this science. B. Adopted two-tier diagnostic tests can filter and inspect whether students sank into myths or mistakes. Except for using POE teaching for the high-score students studied in science, the results of traditional didactic teaching or POE teaching for general students shows obvious discrepancy in the post test which uses two-tier diagnostic tests, and these students may need remedial teaching for myths someday C. During the biochar classes, if a teacher doesn’t timely clarify a student's previous myths when the teaching involves the original knowledge, it may obstruct a students’ learning of new concepts.
