對教材資源的一些討論摘要：本文就筆者在使用北京師范大學版的實驗教材（數(shù)學第六冊）過程中，對教材資源中的問題進行了理解、分析和建議。關鍵詞：科學性；真實性；層次性；繁瑣性；誤解。

2023年，我有幸參加了新課改實驗教材的教學工作，教材一拿到手，我就被那些花花綠綠、生動形象的圖文吸引了，并下定決心，一定要深鉆教材，認真研究。在我使用它的近兩年的時間里，我發(fā)現(xiàn)新教材的可行性特別強，學生腦子靈活、能力強，與此同時我也有太多感受，現(xiàn)僅對教材資源與大家商榷：我們學校是2023年開始使用北師大版新教材的，其中一些圖文我認為容易造成學生的誤解，不利于學生進行有效的學習。圖例的科學性第六冊數(shù)學書第13頁，看一看，說一說下面哪些圖形是對稱圖形（如圖1）圖1圖2紅旗應向一個方向飄，除非旗桿那里有電子吹風機（我想是沒有的），這幅圖有失真實性，孩子們的爭議比較大，有的說不看紅旗，就建筑來說是對稱圖形；有的說這幅圖形對折不能完全重合，說明不是對稱圖形等等。我不知道編者的本意是就是通過這些細節(jié)考察學生對對稱圖形的掌握程度，還是根本沒想到我們的學生會“盯”的這么仔細，但不管怎么樣這幅圖不符合實際。選編的練習容易引起誤解第六冊數(shù)學書第55頁畫
