I waited 14 years to do something that I should have done in my first year of teaching：shadow a student for a day.
    This is the first year I am working in a school but not teaching my own classes.Being the High School Learning Coach，a new position for the school this year，my job is to work with teachers and administrators（管理人員） to improve students' learning outcomes.
    As part of getting my feet wet，my principal suggested I "be" a student for a day：I was to complete all the work of a 10th-grade student.My task was to do everything the student was supposed to do：If there were notes on the board，I copied them as fast as I could into my notebook；if there was a chemistry experiment，I did it with my host student；if there was a test，I took it.
    I could not believe how dog-tired I was after the day，because I literally sat down the whole day，except for walking to and from classes.We forget as teachers，because we are on our feet a lot --- in front of the board，walking as we speak，circling around the room to check on student work...we move a lot.
    But students almost never move，because in every class，the expectation was for us to come in，take our seats，and sit down for the whole class.Therefore，by the end of the day I was eager to move.I had planned to go back to my office and write down some notes on the day，but I was so exhausted that I couldn't do anything but watch TV and I was in bed by 8：30.
    If I could do back and change my classes now，I would immediately change the following three things：
    ①mandatory stretch（強(qiáng)制伸展）halfway through the class；
    ②put a basketball hoop（籃筐）on the back of my door and encourage kids to play in the first and final minutes of class；
    ③build a hands-on，move-around activity into every single class day.
