Liao Shu-chen, who has been a junior high school teacher for many years, notes that during their junior high school years, students experience rapid and violent changes in body and mind. The second year in junior high school is particularly frustrating: some students love to talk back, while others only pretend to obey the rules.
在國中任教多年的廖淑貞老師則指出，國中階段的學生處於身心變化急遽的風暴期，特別是國二，非常「彆扭」，有的愛唱反調，有的則陽奉陰違。
