DIFFERENTIATION

now is 2230, i finished a differentiation class at 2200...the most unsatisfied class in my time of teaching....because i failed to make my students to master the skills and techniques in answering the questions....they did try to let me feel that they had understood....but....their acting was not that convincing...i know they didnt understand....

hai......there is no main point in this post....i only want to stress what is the feeling when i cant fulfill my job.......there are too many things in my mind now....i dont know how to arrange them....

so thats all for today...bye.
