Research On Design And Practice Of Question Strings In Senior High School Chemistry Teaching

With the rapid and continuous development of modern society,education must be in constant reform and development to meet the social development.The goal of modern education must be transformed from the simple inheritance and dissemination of knowledge to the brilliant development and creation.Education is supposed to lay a solid foundation for the growth and development of personal life from the perspective of humanism rather than develop specific talents only.In this situation,countries all over the world have set off a wave of reform in every field of teaching.China is no exception.All sectors of education are encouraged to explore new educational ideas,educational modes and teaching methods,attempting to improve the teaching quality and to promote the development of China's politics,economy and culture.In the August of 2010,considering the actual situation in the school as well as the region,Rudong Middle School of Shuyang County,Jiangsu province where the author works,put forward the highly efficient problem-solving teaching mode after repeated,careful discussion and research.As a chemistry teacher of the school,the author is also actively involved in the study on the concrete application of the mode in chemistry teaching.The high efficiency in the highly efficient problem-solving chemistry teaching mode is achieved via the unique design of the problems.The design of problems as a system can be thought-provoking,developing and improving students' scientific thinking.It enables students to achieve high efficiency in knowledge acquisition,laying foundation for the growth and development of students.The highly efficient problem-solving teaching mode has advantage over the traditional cramming method of teaching In the efficient chemistry teaching mode based on problem-solving,the students are required to participate in the process of knowledge construction through problem-solving so as to acquire knowledge and find the rules.This process can greatly stimulate students' thinking and thinking intensity,and cultivate students' scientific literacy and thirst for knowledge.Thus,students may learn in a more independent and effective way.In addition,the mode may enhance each student's cooperation and communication skills and logical thinking.Through long-term exercise,these advantages will be greatly improved,which will be of great help to the long-term development of the individual.Moreover,in this teaching mode,it is more conducive to the interaction between teachers and students.Students have more time and more interest to participate in classroom activities,enlivening the classroom atmosphere.This thesis makes a detailed interpretation of the highly efficient problem-solving chemistry teaching mode,enclosed with several typical and detailed teaching designs.Then it makes a contrastive analysis of the grades of the experiment class and the control class.Furthermore,basing on the questionnaire and students' subjective attitude of the teaching mode,the thesis analyses the practical application of the teaching mode and finally evaluates the mode.
