一、激趣导入,诱发探究动机作为教师应该在科学教学中巧妙地设计符合学生特点的、学生喜爱的、新奇的活动来激起学生强烈的学习兴趣。如教学“小苏打和白醋的混合”这一内容时,我把实验需要的材料设计成卡通对话——小苏打说:“蒸馒头,做面包,碳酸饮料少不了我小苏打。”白醋说:“凉拌菜,软化血管也少不了我老白醋。”玻璃杯说:“你们俩别自夸了,把你们俩混合在一起还能逞强吗?”通过对话,学生产生了疑问:“把小苏打和白醋混合后会发生怎样的变化?”
First, the introduction of excitement, to induce inquiry motivation As a teacher in science teaching should be cleverly designed to meet the characteristics of students, students favorite, novel activities to arouse students’ intense interest in learning. When teaching “Blend of Baking Soda and White Vinegar”, I designed the materials I needed for the experiment into a cartoon dialogue - Baking Soda: “Steamed buns, bread, carbonated drinks, and ultimately, my baking soda.” “ White vinegar, said: ”salad, soften the blood vessels, and ultimately, my old white vinegar. “ The glass said: ”You two do not boast, you both can be brave?“ Through dialogue, students have questions : ”What happens to the mixture of baking soda and white vinegar?"
