花的结构教学设计
<p>一、教学目标</p><p>认知目标：描述花的结构和各部分的功能，并说明花的主要结构是花蕊的理由。</p><p>能力和技能目标：</p><p>通过解剖、观察花的结构，培养学生的观察能力、实验操作能力、合作能力、思维能力、分析总结及语言表达能力;通过逛花市，培养学生收集知识的能力;通过制作花的贺卡，培养学生的想象力及动手能力。</p><p>情感和价值目标：</p><p>培养学生对美好生活热爱的情感;打开学生的想象空间，溶入亲情、友情，进行情感教育。</p><p>二、教学重点</p><p>花的结构及功能，特别是子房的结构。</p><p>三、教学难点</p><p>花的结构及功能</p><p>四、教学方法：直观教学法、小组合作式教学法、启发式教学法</p><p>五、教学过程：</p><table align="center" border="1" cellpadding="0" cellspacing="0" style="border: 1px solid black;
