Investigation Of High School Students Thinking Of Imagination In Theoretical Study Of Chemical Bonds

The learning of subject core knowledge is an important aspect to improve students' scientific literacy,chemical imagine thinking as the core thinking in chemistry learning,to chemical core knowledge learning has very important significance.In this paper,the core knowledge relevant bond theory of learning in imaginative thoug ht three basic content on the following issues:(1)to understand the situation of high school students thinking of imagination in learning theory of chemical bonds;(2)analysis of high school students to learn the theory of chemical bond imagine thinking the problems;(3)the imagination of high school students made some specific recommendations in the learning culture of thinking in the chemical bond theory.In this paper,as the main method of investigation,the case of high school students to imagine thinking a comprehensive analysis of chemical bond in learning theory,which found that high school students in the study of chemical bond theory thinking to imagine the problems raised on the basis of the specific Suggest.Survey showed that:(1)high school students understand the meaning of the chemical bond in native memory level,lack of imagination thinking;(2)the level of high school students on a bond of understanding the nature of the chemical reactions at low levels imagine thinking;thinking to imagine a case(3)the level of high school students on a chemical bond chemical reaction energy change awareness is not optimistic;(4)for a total of understanding valence bond or not well understood in depth from the electron cloud level,the lack of imaginative thought process activities;(5)the students will fail hybrid orbital theory to explain the construction of molecular models.The analysis revealed that the problems are:(1)the student's own efforts to the extent of the problem,the student foundation is not solid;(2)students' overall planning capacity of knowledge is not enough;(3)lack of teachers in the teaching process for students guide.Aiming high school students to imagine learning bond theory in mind the problems put forward specific teaching suggestions:(1)recognizes the importance of thinking to imagine theoretical study of chemical bond;(2)pay attention to the chemical bond theory knowledge learning culture imagine thinking.
