That is , first , valuing hardware and despising software , repeating in low level , not emphasizing practical results , low utilization ratio and inefficient . second , shortage of training , teachers are poor in information accomplishment . third , the contents of courses , teaching ways and ideas are old 具體表現為:一是信息化基礎建設重硬輕軟,低水平重復,設備配置不重實用、實效,利用率低,功能效率低;二是培訓力量不足,教師信息素養偏低;三是課程、教學方法、教學觀念陳舊等。
Then , according to the current situation of mathematics teaching , it advances four principle of the approach ( the principle of simplifying forms and emphasizing practical results ; the principle of creating settings and studying initiatively ; the principle of stressing the process and encouraging the exploring ; the principle of connecting with the reality and stressing the practice ) . next , according to these teaching principles , it designs the class teaching frame of the approach , as follows : creating the right settings of the problems - presenting the basical teaching problems - solving the basical teaching problems - demonsting the examples - feedback and evaluation 提出了“問題解決”教學的四原則(淡化形式,注重實效的原則;創設情景,主動學習的原則;突出過程,激勵探索的原則;聯系實際,注重實踐的原則) ,并根據教學原則,設計了“問題解決”教學的課堂教學結構:創設合適的問題情景? ?提出基本的數學問題? ?解決基本的數學問題? ?例題示范? ?反饋評定。
