Research On Teaching Effect Of Information Technology In Ionic Equilibrium Of Aqueous Solution

Ion Equilibrium in Aqueous Solution is the third chapter of the principle of che mical reactions published by the People's Education Press.It is complex and theoretical.I t is also a difficult point for high school students to study and a hot topic in the college en trance examination.The traditional teaching method of "one blackboard,one lecture stag e,teacher-centeredness,and students' note-taking not only makes students bored and tire d,but also makes them have a negative attitude to learning,which puts teaching in a very awkward position.The chapter "Ion Equilibrium in Aqueous Solution" shows the chemical phenomena of weak acid,weak base ionization,weak ion and weak acid or weak base coexistence.It teaches students to understand the chemical phenomena of molecule and ion coexistence i n weak electrolyte solution by using the scientific principles of macro and micro,dynami c and equilibrium.It shows students the chemical changes and their reaction rules as well.All of these are inevitably benefial to the development of students' core competence.The author of this paper chooses two classes(experimental group and control class)as the research objects,teaches the experimental group through discovering the teaching d ifficulties,using information technology to design the teaching courseware of micro-visibi lity and theory visualization,and analyzes the differences between the two classes from t he aspects of learning interest,work assignments,questions,concept,comprehension,overal l scores with through the method of periodic evaluation and observation records.This pap er discusses the teaching effect of information technology on Ion Balance in Aqueous Sol ution,and evaluates the results effectively.
