Develops The Student Chemistry Thought Quality Practice Research Using The Contrast Experiment In The Middle School Chemical Teaching

To enhance student's scientific accomplishment as the primary intention chemistry curriculum standard emphasizes " The experiment has the unique function in raising the student scientific thought aspect". The article thinks, to raise student's thought ability may obtain from raising thought quality because the thought quality is the concrete manifestation of thought ability. Through raiseing middle-school student's chemical thought quality may build the solid foundation for the chemical teaching in ability raising goal. This paper inquires into the strategy and the way to train the student thought quality (included thought depth, width, flexibility, nimbility, criticism, creatively and so on)using the massive contrasts experiment as cutting into the spot in the new teaching material in the middle school chemical teaching. Carrying on the comparison test in the natural sciences methodology as the foundation, takes the detailed classification of contrast experiment in the middle school chemistry new teaching material, proposes the principle and the step of contrast experiment designs, improves and supplements some contrast experiments; discusses and puts to the practice to develop the student different thought quality teaching strategy using the different type contrast experiment; Unifying the characteristic of the middle-school student thought development and chemistry discipline estables chemical thought quality diagnosis and the evaluation system by the test question card. The education experiment proved that, The fit and unfit chemistry thought quality directly affects student's chemistry result. Using different type contrast experiment teaching can remarkably enhance student's thought quality. The teaching using the contrast experiment can promote the transformation, in the teacher teaching way and the student studies way...
