The Application of Variant Thinking in the Modeling of“Revenue Generation by Photographing”Task Pricing

变式思维是通过变换同类事物的表现形式,变更研究角度和方法,突出事物的本质特征或本质要素,让学生在变式中进行思维,进而掌握事物的本质和规律。在"拍照赚钱"任务定价建模过程中,运用变式思维,对模型进行逐步改进,依次引入打包系数、倍率等,从而解决建模问题。实践证明,有意识地运用变式思维,可以改善思维方式、提高建模能力。

Variant thinking focuses on altering the manifestation of similar matters,modifying the research prospective and approach,highlighting the nature and essential elements of all matters,in order to stimulate the students＇ variant thinking and learn about the nature and law of things. In the modeling process of ＂revenue generation by photographing＂task pricing,it has been found that the use of variant thinking,gradual improvement in models,the successive introduction of package coefficient,multiplying power can effectively resolve the modeling problems. The deliberate use of variant thinking is helpful in improving thinking patterns and enhancing the proficiency in modeling.
