Teaching procedures:
Step 1 Warming up
The teacher starts the lesson with a small guessing game. Students are divided into several groups. A question “How many languages are there in the world?” is presented on the screen. Answers varying from “more than 2000” to “more than 7000” are also presented on the screen. Students are encouraged to guess the answers. And students who guess it right can gain points for their groups. And the answer is more than 6000.
Step 2 Presentation of a card
Present a new year’s card to the students. Ask them to recognize the languages printed on the card. If some students could read some of the languages, encourage them do it in the class.
Step 3 Discussion of emoticons
An emoticon is presented on the screen. Two questions “We often see this while chatting on line or in our text messages, what does it stand for? Could you give some other examples of emoticons?” are raised on the screen as well. Students are encouraged to utter their ideas freely. And the teacher really should appreciate their answers and the opportunity to learn from the students.
More emoticons are presented on the screen to let students guess or tell the meaning of them. This can also be involved in the competition if the teacher wants it to be interesting.
Step 4 Discussion on other forms of languages
Tell students that a language is not only something that can be spoken or typed. Show them a picture of sign language on the book. Give a short introduction of the meaning of the gesture. Present more pictures of sign language and get students to guess their meaning.
Step 5 Introduction of Braille
Deaf people can use sign language to communicate. Ask students “How can blind people read the language in the books?” Present a picture of Braille alphabet on the screen. Ask students to feel the dots on their cash if possible.
Step 6 Discussion on communication between animals
Raise the question “Do you believe animals can also speak languages?” Let students express their idea about communication between animals.
