Research On The Design For Comprehensive Chemical Experiments In Middle School

Chemistry is science based on experiment and experiment is basis of middle school chemical teaching. Through experiments we can help middle school students form chemical ideas, deepen their understanding of fundaments and basic knowledge of chemistry and master basic experimental skills, Besides, it can help foster middle school students' abilities of observation thinking and imagination through watching chemical phenomenon together with analyzing reasoning, and deciding. Therefore, experiment teaching is an effective way of comprehensive chemical teaching.Of all chemical experiments, the most vivid and active teaching method is comprehensive and design experiments. The following paper discuses the necessity, feasibility and designing principle of carrying out comprehensive chemical experiments in middle school. There are also seven comprehensive experiments applicable to middle school students, when designing these experiments, we synthesize the preparation, nature and application of chemical compound, lessening the dull experiments that use test-verify way and spoon-feeding way of teaching.In addition to this, we connect experiment teaching with practical production and real life, opening up the students field of vision and arousing their interest in probing things. While compiling these experiments, we raise some inspiring questions. Lead students to think actively and cultivate their think abilities.To carry out comprehensive experiments in middle school is a new question for study. Here we just have a preliminary try at it, aiming to get more valuable opinions. We hope our ideas will help promote. Further reform in the teaching of middle school chemical experiment.
