Research on Implementing the Core Literacy of Intuitive Imagination in Senior High School Mathematics Teaching

In the process of senior high school mathematics learning, improving students' intuitive imagination core literacy can enhance their ability to combine numbers and shapes. It also plays an important role in developing geometric intuition, spatial imagination, and understanding the essence of things. We first summarize the current strategies for cultivating the core literacy of intuitive imagination, then provide an overview of the intuitive imagination in core literacy. The author interviewed 12 senior high school mathematics teachers who were teaching locally in various cities in Shandong province with a large population and balanced education levels. Through interviews, it is learned that, students always lack numerical evidence when doing exercises, and most student s only look at questions without sketching. During teaching, teachers closely follow the textbook but lack explanation of flexible problem-solving methods using geometry, and they may experience improper use of teaching aids or incoherent explanations. Finally, corresponding strategies are provided.
