① 實驗設計將學生分組，利用桌上的器材進行探究（幻燈片展示）這個實驗難度較大，為了降低難度，為實驗探究鋪下第二臺階，要求學生先分小組討論以下問題（幻燈片展示）有些學生可能不知如何下手，我會要求學生先閱讀課本中的實驗描述從中得到一點提示，再讓一兩個小組同學回答，這樣既體現(xiàn)了學生學習的主體性又可提高學生自主思考和語言表達能力，之后我再進行補充完善（幻燈片展示答案），并用幻燈片把實驗步驟展示出來，在學生實驗過程一直保留，使學生能朝正確的方向進行猜想和操作，為實驗探究鋪下第三個臺階。② 實施探究在學生分組進行探究過程，教師巡視解惑，隨時觀察學生情況，解答學生提出的問題，還可用自言自語方式提示應注意的一些問題，如儀器的正確使用，操作的規(guī)范等，幫助學生盡量在規(guī)定時間內(nèi)順利完成實驗。

人教版高中英語必修4A taste of English Humor說課稿3篇
Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill
