Analysis The Learning Difficulty Of The Undissolved Electrolyte Dissolved Balance And It Teaching Strategy

"Dissolve the undissolved electrolyte balance" is very important in high school chemistry four balance,it is an important basic theory of chemistry module,content,strong logicality,students in the learning process and teachers in the process of teaching there are common difficulties."Dissolve the undissolved electrolyte balance" is the emphasis and difficulty in high school chemistry learning,the former concept is more distracting,students learn in this may result in more or less psychological barriers.Although from the point of view of the students have a certain ability of abstract thinking and imagination,but can’t see chemical reaction process of scratching,teacher’s language and the thinking method of ordinary alone is difficult to understand and grasp the theory.In the traditional way of teaching,the teacher speak pure theory,students to practice again,only with the teacher’s explanation,it’s hard to leave deep impression in the minds of the students,only by rote,effect is little,caused the difficult in the process of teachers in the teaching,the teacher speak of hard work,students learn the effect is bad.This study in order to solve this problem design questionnaires and interviews analysis students in learning as part of the content of trapped in learning trapped because of the effective teaching strategies are put forward.Choose this paper has studied the dissolve the undissolved electrolyte balance section of zhang ye,gansu province secondary school students were investigated,based on the analysis of the results of the survey,the author found that students in learning to"dissolve the undissolved electrolyte balance" reasons for learning difficulties mainly include the following:(1)the lack of learning interest and motivation,(2)lack of knowledge and ability to the starting point of(3)the influence of learning methods and habits(4)the effect of learning box(5)the lack of teachers’ teaching ability.For "difficult let dissolve electrolyte balance" the causes of the formation of learning difficulties,the author put forward the corresponding teaching strategies has the following points:(1)the leading study case writing class,in spreading knowledge construction bridge(2)the use of scientific and reasonable teaching materials,grasp the deep breadth of knowledge(3)the scientific use of a variety of teaching methods,stimulate students’ interest in learning(4)to form a cooperative learning group,and(5)the poor student mutual learning science moderate assignment,promote effective knowledge transfer.
