All middle school students are at different stages of development: some students have matured considerably, while others still have a long way to go. Hunt, Wiseman, and Bowden conclude that when examining attitudes and behaviors, some middle school students are "childlike" while others are "deeply involved in the complex characteristics of the adolescent lifestyle" (1998, p. 57). They also establish that middle school students are in a period of “significant transition,” a time with which some struggle, while others thrive on the change. (Hunt, Wiseman and Bowden, 1998, pp. 60-61). The middle school age group is generally distinguished by children and adolescents aged 10 to 14. This age group was not distinguished until the 1980s (Hunt, Wiseman, & Bowden, 1998, p. 58), coinciding with the later development of college. (compared to college). These students find themselves in a stage invented by Donald Eichhorn called “transesence” (Manning & Bucher, 2012, p. 5). In general, transesence students share seven developmental tasks identified by Thornburg (Hunt, Wiseman, and Bowden). , 1998, p. 58-59): They become aware of physical changes that are occurring rapidly. They are able to organize their thoughts and solve problems better. They learn new social and sexual roles. They begin to identify with existing stereotypes. They begin to develop important peer friendships. They gain a sense of individual independence. Their moral development and values ​​mature. Because of this complex range of developmental levels, middle school teachers need to understand what existing stereotypes are. what is the level of the students, as well as how they can approach the teacher's challenge as a whole...... middle of document ......012).
