《初中數(shù)學幾何模型精講》系列課程，是以現(xiàn)行義務教育階段中學數(shù)學教材知識為基礎，以考拉教研組金牌數(shù)學教研團隊根據(jù)中考熱點題型提煉而出的“幾何模型”為主線，結合中學階段學生的學情學力而精心設計的精品課程。該課程具有趣味性濃、知識性強、條理清晰、通俗易懂等特點，其中的每一講都以古典武俠風的故事開篇，采取“提出模型——分析模型——講解模型——應用模型——鞏固練習”的五步結構模式，引導學生理解相關幾何模型的特點及用法，讓他們在趣味中提升，在解題中明了。我們希望通過深入淺出的分析和講解，啟發(fā)學生的讀圖能力和解題思維，培養(yǎng)出對相關幾何問題“見招拆招”的功底，較終實現(xiàn)“庖丁解牛、游刃有余”的目標。
