1、1High school chemistry experiment on innovation cultureChemistry is a laboratory-based science, years of teaching proved: chemistry experiments for chemistry students is not only the knowledge, understanding of chemical laws, and the formation of chemical concepts, an important way to improve capabi
2、lities, and the process for students innovative spirit and ability, is not a substitute for other disciplines, so we must be based on this chemistry experiment based on students ability to innovate and strive to build the House, I believe that the following aspects should be implemented. First, chan
3、ge the demonstration experiment for students and teachers and students together to complete the experimental group Professor Yang Chen once said: Chinese childrens interests and abilities in hands-on are obviously not as good as European and American children, mostly without hands-on opportunities.
4、In fact, not only our children so that our students in the international Olympiad theoretical results are always living in the edge, experimental results tend to be lagging behind other 2countries. The main reason is: high school textbooks in the experimental arrangement is not too much already, som
5、e teachers do not consciously attempt to take year round, instead of using students to explain and demonstrate the hands-on operation, some simply to replace the stylized writing training the experimental group of students. In view of this, educators should strive to do through hands-on practical ac
6、tivities to develop students creative ability in practice. Specifically, this experiment can demonstrate to students some all student groups to do experiments or experiments, such as ethylene and nature of laboratory experiments previously always prepared by the teachers contract to complete, studen
7、ts do not think, was appealing in mind, teachers and students together to complete now to enable students to participate, through the reaction mixture preparation and ignition of ethylene gas to develop a good psychological quality, strict control of temperature, the reaction solution, train the stu
8、dents a rigorous scientific approach; temperature is too low or too high temperature may cause any results, what to do? these will stimulate students to seriously consider the design approach, innovative thinking to develop students ability 3and innovative ability. color change reaction solution to
9、acidic KMnO4 solution and ethylene, bromine faded experiment, to develop the students observe and analyze the innovative ability grouping experiments better to provide students with the participation of all, the chance yourself. In this process, the winners reap joy, thus to stimulate their interest
10、 in innovation and passion, losers from gaining experience and lessons learned to stimulate their serious consideration, to be creative, so that the teaching process as students learn to seek knowledge, foster innovation and practical capabilities. Second, change the validation experiments to explor
11、e the experiment Validation experiments have been learned through experiments with chemical knowledge to prove its accuracy, the students in the state of passive acceptance of knowledge, and to explore practical means of chemical experiments, based on scientific analysis and integration through the
12、thought process to obtain knowledge of a test, this process requires students to have more thinking and discussion, students explore knowledge in an active state, to cultivate creativity in our students is 4very beneficial for example, in learning the nature of Cl2: First of all doubts and questions
13、: Cl2 can dissolve in water? Cl2 can react with water it? If, resultant is what? Experiment to explore: (1) in two bottles of any color similar to the chlorine by adding a small amount of water to take a bottle full oscillation, with another bottle of chlorine to compare their color, the color of it
14、s solution with distilled water compared to what conclusion? ( 2) of chlorine were added AgNO3: solution and dilute HNO3, NaHO2 solution, blue litmus test solution, respectively, to see what phenomenon? conclusion how? (3 pure dry Cl2 through dry and wet blue litmus paper and observe what phenomenon
15、? say what? Scientific analysis: (1 bottle of reagent water gas lighter color, the color turns yellow-green solution; (2 white precipitate, bubbles, fade after the first red, (3 dry test strip does not change color, moist strips After the first red fade. Conclusion: Chlorine can dissolve in water, b
16、ut solubility is not, part of Cl2 dissolved in water reacting with water, C1-, H +, HCIO. Dry C12: do not have the 5bleaching, the bleaching effect is HCIO. Change validation experiments to explore the experiment, active in the students thinking, to stimulate enthusiasm for the initiative to actively explore and enhance self-confidence, the activation of innovation. Third, carry out experiments designed to stimulate innovation Practice is the cra
