Nanchong, Sichuan: Longmen Middle School teacher's biology micro course "Epigenetics" won the first prize in the municipal competition

Recently, the results of the 2025 Teacher Digital Literacy Improvement Practice Activity in Nanchong City were announced. The biology micro lesson "Epigenetics" jointly created by Li Jia, Li Furong, and Chen Lihua from Nanchong Longmen Middle School won the first prize in the high school section of the basic education group with high-quality content and distinctive practical characteristics.

This micro course focuses on core biological literacy, with "case investigation" as the narrative thread. Starting from the differences in traits between identical twins, combined with mouse hair color genetic experiments, it explores the differences between classical genetic predictions and actual results, revealing the concept and mechanism of epigenetics, and expanding related examples. This micro lesson design transforms knowledge points into clues for solving cases, allowing learners to master knowledge in the process of "solving puzzles", and finally return to the case to identify the "real culprit", combining fun, exploration, and application.

This award is not only a gratifying reward for the teachers' deep cultivation of teaching, but also a reflection of the school's commitment to "digital empowerment education" and the promotion of teaching innovation. The school will continue to strengthen the cultivation of teachers' digital literacy, promote the deep integration of information technology and education, encourage teachers to constantly explore new paths and methods of digital teaching, and continuously enhance the school's ability to educate students through digital teaching.
