Abstract: teaching activities in recent years really need to apply and create more methods and techniques to integrate into teaching lessons, especially at the lower secondary level. Realizing the importance of Industry 4.0 and the strong trend of globalization, as well as the foreign language ability of current middle school students, has improved significantly compared to previous generations, so English teachers play an important role in promoting and developing foreign language ability for children. In this article, I would like to present and propose solutions to develop 21st-century skills through the 9th-grade English Reading class, by applying KWL techniques and team working, in order to improve the quality of teaching activities, helping them confidently develop most of the skills required of the 21st century and building a knowledge base to prepare for the 10th-grade entrance exam.
