It has___________. It can________.</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">同学们都争着说,你一句,我一句,不仅巩固了旧知识,也活跃了课堂气氛。同时,同学们对如何描述“</SPAN><SPAN lang=EN-US>hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">的特征也了解了不少。在学习了单词之后,我提出第二个学习任务:你们知道母鸡与其他动物不一样的地方吗?同学们互相讨论。之后我呈现句型:</SPAN><SPAN lang=EN-US> It can lay eggs. </SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">并让同学们来模仿“</SPAN><SPAN lang=EN-US>hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">,同学们一边说,一边学“</SPAN><SPAN lang=EN-US>hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">的样子,兴趣昂然。最后,我在模仿“</SPAN><SPAN lang=EN-US>hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">动作的同时,模仿他们的叫声,此时,提出第三个学习任务:学会用</SPAN><SPAN lang=EN-US>They go”_________”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">来模仿动物们的叫声。通过这三个任务的学习,同学们都有所收获,能力较弱的学生只需要完成第一个任务,而能力较强的学生可以完成</SPAN><SPAN lang=EN-US>2~3</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">个学习任务。</SPAN></FONT></P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt 18pt; TEXT-INDENT: -18pt; LINE-HEIGHT: 150%; mso-list: l0 level1 lfo1; tab-stops: list 18.0pt"><SPAN lang=EN-US style="FONT-FAMILY: &#718;&#805;; mso-fareast-font-family: &#718;&#805;; mso-bidi-font-family: &#718;&#805;"><SPAN style="mso-list: Ignore"><FONT size=3>2.</FONT><SPAN style="FONT: 7pt 'Times New Roman'">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </SPAN></SPAN></SPAN><FONT size=3><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">教学方法丰富多样:</SPAN><SPAN lang=EN-US><A href="http://lwcool.com/jx/showcls.asp?id=2&amp;parent=0"><SPAN lang=EN-US style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'"><SPAN lang=EN-US><FONT color=#000000>教学</FONT></SPAN></SPAN></A></SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">方法总是相对而言的,它总是因课程,因学生,因教师自身特点而相应变化的。有效的课堂教学理不开有效的教学方法。为了提高学生的学习兴趣,使学生更主动的参与到学习过程中来。我采用各种有效的教学方法,来激发学生学习兴趣,如:用</SPAN><SPAN lang=EN-US>”hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">的剪影来让同学猜一猜这是什么动物,或是让学生自编一个短剧,用学过的或新授的句型来描述</SPAN><SPAN lang=EN-US>”hen”</SPAN><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'">的一些生活习性。这样,使得枯燥的机械性训练变成了一个有趣的教学活动,使学生兴趣盎然。其目的就是引导学生在情境中主动地实践、体验语言,从而让学生真正获得一种交际能力。</SPAN></FONT></P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; TEXT-INDENT: 24pt; LINE-HEIGHT: 150%; mso-char-indent-count: 2.0"><SPAN style="FONT-FAMILY: 宋体; mso-hansi-font-family: 'Times New Roman'; mso-ascii-font-family: 'Times New Roman'"><FONT size=3>总之,这堂课经过反思与重新设计,学生的学习主动性得以提高,学生的知识面得到横向的拓展,学生能在学中用,在用中学,学用结合,学以致用。</FONT></SPAN></P> <P class=MsoNormal style="MARGIN: 0cm 0cm 0pt; LINE-HEIGHT: 150%"><SPAN lang=EN-US style="FONT-FAMILY: &#718;&#805;"><o:p><FONT size=3>&nbsp;</FONT></o:p></SPAN></P>
