As a preservice teacher in Valaya Alongkorn Rajabhat University, I embarked on a transformative journey under the tutelage of two seasoned educators, Mr. Naphat Charoenkrittayawut, teaching Grade 9, and Ms. Navalak Saisutthilak, instructing Grade 12. Stationed at the Royal patronage Demonstration School, my role was not just that of a learner, but an observer tasked with exploring the dynamic world of foreign language education. Over the course of 20 days, I had the privilege to delve into the strategies and techniques of these two English teachers, spanning both junior and senior high school levels.  This blog chronicles the pedagogical content I discovered during this immersion in the Foreign Language classrooms, offering insights into teaching methods, learning materials, technological integration, and authentic assessments.
