摘　　要：分析了“溶解度”实际教学中存在的2个问题:直接给出概念难以让学生真正理解,纯粹的知识性教学难以体现学科知识的价值和意义。提出在“溶解度”教学中融合真实工业生产和活动探究,能帮助学生全面深入地建立概念、理解概念和应用概念,并感悟科学本质和学科价值,以“矿盐”为主题,呈现了融合盐化真实工业生产和活动探究的教学实录,包括矿区采盐、厂区制盐和盐穴利用等3个环节。通过课堂生成分析了教学效果、存在的问题及教学的改进方向等。This paper analyzes two problems existing in the actual teaching of"solubility":it is difficult for students to really understand the concept directly,and pure knowledge teaching is difficult to reflect the value and significance of subject knowledge.It is proposed that the integration of real industrial production and activity exploration in the "solubility"teaching can help students comprehensively and deeply establish concepts,understand concepts and application concepts,and feel the scientific essence and discipline value.With the theme of "mineral salt",it presents the teaching record of the integration of real industrial production and activity exploration of salinization,including three links:salt mining in mining area,salt making in plant area and salt cave utilization.Through classroom generation,this paper analyzes the teaching effect,existing problems and the direction of teaching improvement.
