The Digesting Of Searching Experiments And Validating Experiments In Chemistry Teaching Of Middle School

Since putting the innovation of the courses into effect in the year of 2001, the chemistry which is a subject based on lots of experiments brings into effect in the part of changing students' study mode and in the part of facilitating the development of students' throughways. Chemical experiments have also became the more important parts which needed put really into effect in during the course of designing curricula, compiling the teaching material and practicing the teaching. The conventional teaching of chemical experiment gave priority to experiments that were used to validate some theory, but the teaching that based on searching experiments has been fashionable now. Lots of teachers think that only searching experiments are the best now. Resulting from these above, some people have the following understanding: in order to do searching experiments, some teachers changed showing experiments into manual experiments by students, or only did the searching experiments and cast away the validating experiments. The teachers having above understanding have not realized the different teaching functions of validate experiments and searching experiments that they have diverse respective good or bad effects. They also have not realized that they should decided to use searching experiments or validating experiments to adapt to the developments of students' ideation and emotion, according to goals, contents, objects and conditions of teaching. As a result, I investigated the digesting of searching experiments and validating experiments in the school chemistry experiments teaching.This searching subject has four parts: Cognition of five Karamy middle schools' teachers on validating, exploring experiment and students' capability degree is analyzed in the first part through questionnaire design, investigation and statistics. The need and the feasibility of digesting of validating experiments and exploring experiments are also putted forward. The meaning, teaching function, excellence, abuse of validating and exploring experiment is discussed and the two teaching model is analyzed in the second part. In third part, the influencing factor of digesting on validating and exploring experiment is analyzed, and then some good cut-in points for the two experiments conformity is concluded for teaching practice, at same time some samples explain that. The evaluation and summing-up for students' grade, handle skill, thinking character and interest are gained through questionnaire, experiment etc method.The aim of this subject: I aim at fostering students' full characters and their...
