The Design Research Of The Middle School Chemical Experiment In Aesthetic Perspective

Since1950， scientific literacy become a new word attracted all attention in theworld， one of the themes of current science education highly pays equal attention to“science and humanities”，the course object of the foundation education emphasizes tocultivate students with scientific and humanistic accomplishment， with a strong andgood psychological quality，and to develop a aesthetic taste and healthy way of life".Then，the modern brain science research shows that scientific and comprehensiveintegrated development of the student’s left and right brain can avoid to isolate toknow the subject knowledge logic structure and situations. So the cultivation of theaesthetic feeling is a meaningful new subject which is worth exploring in scienceteaching.This study use the science and experimental design as the research basis，defining the chemical science， putting forward the education of humanisticpsychology and aesthetic psychology as the theoretical basis，analyses that chemicalexperiment teaching function, teaching objectives and the experiments’ improvementand innovation strategy are the embodiment or projection of the aesthetic.Combined with the aesthetic psychological structure design questionnaire,through descriptive analysis, we understand the students in the experimental aestheticfeelings show positive attention, but the aesthetic consciousness is lacking. Because ofthe examination-oriented education of oppression and the direction of the collegeentrance examination evaluation, aesthetic experience is conforming, and pay toomuch emphasis on experiment is beneficial to master chemistry knowledge; Aestheticpsychological tendency obvious, but the implementation of the aesthetic creation islack of support.This study regards the experimental design as its foodhold, analyzesexperimental apparatus based on multiple attribute of beauty, and interprets theexperiments in the teaching meterial based on basic categories of science: harmony,singular, simplicity and symmetry. In the first case, the author integrates the chemistryhistory of experiments of making alkali, and simulates the industrial productiondesign into simple experiment operating device. In the second case, the experiment ofextracting iodine form kelp, the author optimizes the experiment using orthogonal test, and comes to a conculsion: under the atmospheric pressure, ashing using theevaporating dish, using the mass fraction of H2O2for10%, adding10drops sulfuricacid for3mol/L, which belongs to the optimum conditons for the experiment, aregood for formating the experiment aesthetic feelings and experiences. In the third case,the author designs two simple experiments, reflecting the singular of science beauty,and symmetric category, strengthening the aesthetic experience of chemicalexperiment.
