The Development And Application Of High School Chemistry Guided Learning Case

The core concept of the new curriculum reform is "people-oriented,student oriented",advocate studying must be based on the students as the main body,teachers as the leading,change the way of learning.Therefore,teachers should pay attention to guiding students to conduct autonomous learning,cultivate students' innovative spirit and practical ability,change their learning methods and habits,and form the habit of autonomous learning and lifelong learning ability."Guiding learning case" teaching mode is under the requirements of the new curriculum reform,drawing on Anqiu No.4 and Qinyang Yong Wei school of successful experience in reform,the creation of a to develop their design guiding case as the carrier,efficient application in the classroom for guiding students positive thinking,self learning and the teaching mode of learning,cooperative learning and overall development.To determine Ruyang County first senior high school part of students as the research object,through the questionnaire survey,the collective research,with the development of the students in our school teaching case,and the theoretical basis of teaching of "guiding case" teaching mode was discussed,on the "Guide Detailed description of learning " teaching mode to follow the principle of teaching,including the main principle,explore the principle,gradient principle,the principle of innovation etc..According to the nature of the teaching content,we divided the chemistry course into the new lesson,the review lesson,the exercise class,the experimental class and so on,the class type is different,the teaching method,the thought is also different."Guiding case" teaching mode in high school chemistry of different class teaching process and teaching case is introduced in this paper,and the teaching of attention and teaching reflection,further to solve the idea of the new curriculum in the teaching practice in a mere formality of problem,improve the students' learning autonomy.First,to establish the class of 2013(4)class as the experimental class,a high(5)in the control class and two classes are for 70 people,which because the average placement,so two classes of students intelligence levels and chemical grades in the same level,teachers of all subjects preparation is the same.Then,experimental class implementation of the "guiding case" teaching mode(to school development,the preparation of guiding case based teaching),control class uses the traditional teaching mode(only rely on textbooks and general exercises were teaching,chemistry teachers with a teacher.After a period of study,the students in the two classes of chemical examination results for statistical analysis of the pretest,mid test and post test.The results show that in the pretest and posttest scores reached significant difference level(measured in Z0.05: Z=2.00> =1.96: Z=2.24> Z0.05 =1.96;after the test,at the same time from the end)the scores of students in experimental class,class 4 of the total number of on-line better than the control class class 5,class 4 as the experimental class above the second line of the number 25,on-line rate was 35.7%,and the number of on-line control class is 16,on-line rate of 22.9%,the experimental class line rate than control class 5 class high 12.8 percentage points;the experimental class three above the line number for 60 people,three more than the line rate is as high as 85.7%,than the control class line number is 47,on-line rate of 67.1%,up 18.6 percentage points.These data can be a powerful description of "guiding case" teaching mode of practice research has very good effect,can effectively improve the students' grades.At the same time,the implementation of the different stages of "guiding case" teaching mode in the experimental class,we conducted a questionnaire survey and interview of the students,through the summary,compared with that of,students and the teaching mode of "guiding case" has been basically adapted to,adapt to the rate increased from 40.0% of the initial to 76.8%.At the same time,learning interest and enthusiasm of students were improved,self-learning ability,research ability,cooperation ability and learning achievement have great progress and improvement.The teaching practice results can be explained,students like "guiding case" teaching mode,and have basically adapt to this model,in the chemistry teaching to carry out "guiding case" mode is helpful to cultivate students' autonomous learning ability,can mobilize the enthusiasm of students and learning interest,help students to develop good study habits,promote the chemistry learning performance and overall quality raise,and for the future of students learning and development created good conditions,at the same time,reduce the burden on teachers.Students to truly become the masters of learning,creating a win-win situation.
