Application Of The Control Experiment In The Chemistry Teaching In Senior High School

The control experiment is an important means of chemistry experiment teaching, is one of the successful case into the chemistry experiments from the clinical diagnosis and treatment, control experiments have accounted for a large proportion of. the middle school chemistry textbook and the students’ experimental ability identification and assessment. A comparative experimental study is the main content of the students knowledge about experimental condition, process design, observation and conclusion analysis and control. This requires teachers to control experiment method in the process of teaching and more mining information hidden behind the textbook experiment, it also guide students to analyze the connotation of control experiment and improve the ability of solving problems and science quality objective.Experimental teaching is a key and difficult problem in the teaching of chemistry, how to carry out the effective chemistry experiment teaching is and more and more popular, control is a scientific learning method and plays an irreplaceable role in cultivating students’ thinking ability, the experiment process requires students use brain, eye and hand, after experimental operation, rigorous, careful observation and logical reasoning, they draw a scientific conclusion. This topic study chemical experiment teaching can promote students’ thinking, effective operation, observation, perception and problem solving ability.This topic analyze the experimental content, presents the design principle and process control experiment, classify the experimental in high school chemistry textbook, analysis the different types of control experiment teaching content, improve the control theory and feasibility experiments applied in teaching. The topic take the typical subject in high school chemistry teaching as specific examples to explain the chemical knowledge teaching process design, evaluation methods and the attention matters. We hope that this topic research can provide some useful reference for educators, so teachers will pay more attention to students’ strict scientific attitude and the ability solving practical problems, in order to cultivate all-round development people.
