The Study Of Teaching Strategy About The Junior Chemistry Homework In Different Levels

The request of the curriculum standard about the chemistry task is: “to reflect the quality education,to strengthen the contact with social reality and real life.We should pay attention about the ability of using the basic knowledge basic skill to analysis and solve problems,and it is contribute to solve problems creatively ”.But teachers often arrange the “one size fits all”homework,creating students appear the phenomenon of “Hurry” or “ Eat”,thus the effect of homework is harmful to exert effectively,the development of every student is harmful to promote.Thus,in order to complete chemical homework mission better,the students in different levels can finish homework easily,pleasure and effectively,teacher can try to arrange the homework that is in difficulty difference and the amount of homework is difference.Through referring to a large number of literature,discovering it is seldom about the levers chemical task,so this paper based on the new curriculum requirements for chemical task and the study of situation homework,according to the difference for students and analyzing the examination questions.I carry out the teaching strategy of levels homework,in order to change the situation chemistry homework.Under the premise we should respect the students difference and reduce the burden and efficiency,let each student do suitable homework,thus improves the role and efficiency,to improve the students learning initiative and enthusiasm.Because of students difference and the learning styles differences,lead to the same homework that can create the different pressure and mastery,so we should arrange the homework in different levels.In the implementation process,the first is students stratified,then task stratified,the last I carry out the teaching tactics from three areas that is consist of guide stratified,correction stratified,evaluation stratified.Using the way of arrangement levers homework,causing the result that the score isbetter than the beginning,the interest in learning and the initiative is much more promotion.The following conclusions: the first,the teaching strategies of layered homework that is effective;The second,this topic conforms the teaching ideas about according to their aptitude,on the basis of the diversity of students,the students in the line with the law of development.The last,the issue raised by a hierarchical arrangement of chemistry homework policy effect that is remarkable.Students achievement has more obviously improving than the tactics before the implementation.
