Content Reconstruction of High School Whole Book Reading Instructions Based on Big Ideas—Taking the Reading Instruction of Dream of the Red Chamber as an Example

At present, in the practice of whole book reading teaching in high school, the selection of teaching content is still a matter of concern, which is arbitrary or deliberate. Therefore, the introduction of the Big Ideas to determine the content of whole book reading teaching in a scientific way has its practical motivation and bilateral value for teaching and learning. In the instructions of whole book reading in high school language, the extraction of big ideas requires initial definition and subsequent validation. The initial definition follows the top-down path, including "applying disciplinary thinking" and "relying on learning task groups"; the subsequent validation follows the bottom-up path, including "Make a reference to bibliographic genres" and "Analysing students' learning responses". As a key reading book in high school, Dream of the Red Chamber is an example to present the reading teaching content based on the reconstruction of big ideas with certain reference value.
