On Wednesday, May 04, 2022, Mrs. Pheakdey Men led the 12th grade students of American Intercon School, Mao Tse Tong Campus to conduct an experiment on “Protein Identification” in Biology. The purpose of this experiment was to provide students with a better understanding of the lessons that could provide real knowledge and enhance their memory in the study of theory. The experiment went smoothly as expected, and the teacher successfully achieved the objectives of the lesson. The students gained knowledge, skills, and insights into the actual experiment compared to the lessons taught by the teacher in the classroom. At the same time, students actively paid attention and participated in the class with the classmates.
