Under the framework of inductive and deductive methods, the course leads students to explore the mysteries of crop circle graphics. The inductive method is used in the course to extract information from reading articles and conduct comparative analysis. After summarizing, 3-4 hypotheses are obtained, and then the interpretation method is used as a framework to lead students to explore. This includes the exploration of human nature through educational drama, the expression and transmission of symbols through performing arts, and the inclusion of natural science experiments as one of the methods of inquiry. Let the learning of knowledge come from the desire and pursuit of knowledge, and the cross-domain nature of the curriculum is the essential driving force for the pursuit of the truth. The virtual goals come from the analysis of crop circle graphics, while the actual learning goals include information management/experimental science/interpretation of symbols/mathematical reasoning/image analysis/imaginative creation, etc.
