Science versus Nature教學設計

  reading (1)
teaching objectives:
1.to reinforce students’ comprehension of the text and improve their other skills by participating in all the activities.
2.to help students know the widespread discussion about cloning and hold their own attitudes towards it.
3.to enable students to master the reading strategy and become more competent in reading articles related to science.
teaching focus and difficulties:
1. students can work out the meaning of difficult or unfamiliar scientific terms with reading strategy.
2. students can hold their own opinions on the base of reading the article.
teaching aids:
the multimedia
brief teaching procedures:
step1 lead- in
     check the homework. encourage students to share their sources relevant to cloning technology with the whole class. tell students that cloning has been the subject of scientific experiments for years. the recent success in cloning animals has resulted in fierce debates between scientists, politicians and public.
step2 reading strategy
     get students to go through the reading strategy, and make sure that everyone of them understands how to work out the meaning of these scientific terms.
step1 begin by reading the first and last paragraphs for an idea of what the article is about.
step2 circle any words you do not now. question things you do not understand or that do not appear to make sense.
step3 read through the article a few times, and make sense of the scientific terms upon further readings.
step3 first reading—main idea
     ask students to refer to the reading passage and find out the main idea.
     (the reading passage is made up of a newspaper article about cloning and two readers’ letters. we will be given information about how cloning is being researched and the different attitudes towards it.)
step4 second reading—understanding scientific terms
     ask students to circle the unfamiliar words or things they do not understand while second reading.     (for example: embryo, tissues and organs, interfere with nature, etc)
step5 third reading—detailed information
     ask students to read only the article carefully, and finish the following exercises:
     1. what are the different attitudes towards the success of cloning a human embryo?
  on the one hand (valuable tissues and organs can be produced and be used to save human lives)
