  • 第6题:

    资料:Special needs students can not only learn from regular education teachers, but can participate in collaborative learning with mainstream students as well. Collaborative learning allows students to work together in groups to complete lessons and assignments.
    A number of educators with inclusion classrooms are realizing the benefits of collaborative learning and special needs students being placed in small group environments with regular education classmates. Collaborative learning allows students to converse with one another and brainstorm together in order to find solutions to problems or to complete an assignment. This type of learning allows students of varying ability levels to lend their individual strengths to the group as a whole, thereby encouraging an appreciation of diverse ideas and approaches to problem solving.
    Teachers can choose to implement several different types of collaborative learning strategies, depending on the needs of students and the focus of specific assignments. Examples of small-group collaborative learning methods are:
    1) The Think-Pair-Share strategy, which involves each student in the group taking one minute to formulate a response to the teacher's question, then sharing individual findings with a partner. After collaborating in pairs, students can then share input with slightly larger groups or with the entire class.
    2) The Simple Jigsaw strategy, which involves four-person teams splitting a teacher-assigned task into equal parts. Each student in the group acts as an "expert" on one section of the assignment and meets with corresponding "experts" in other groups for discussion and task mastering. Students then return to their initial teams to share their knowledge of the task with other members.
    3) The Three-Step Interview strategy, through which students initially break into pairs and take turns interviewing one another about an assignment. Each pair of students then combine with another pair in order to enhance the discussion.
    4) The Numbered Heads Together strategy, where each team member is assigned a number, then instructed to collaborate on a question. The teacher then calls a number randomly, and the student in each group who has that number acts as spokesperson in answering the question. Each student must be prepared for the possibility of having his or her number chosen.
    The benefits of collaborative learning and special needs students having the opportunity to engage in small group tasks can produce positive results in regard to classroom organization and management. Teachers who research tips on collaborative learning and implement the practice with students are likely to have a successful inclusion classroom.

    What is the most distinct feature you think by the term “inclusion classroom”?( )

    A.It is desired for students with special needs
    B.It is tutored by regular teachers for mainstream students
    C.It is planned for collaborative learning by mainstream students
    D.It has students with special needs and regular education classmates

    Step 2: Presentation
    Draw a ear on the blackboard and ask students what it is. Write down the word. Then ask what ears can be used to, and they will say we use ear to hear something. Write down word “hear”. Then do the action of hearing and put hands near the ear, and write down the word “near”.
    Ask students to read the three words after the teacher, and find out the similarity among them. After discussion, they will say all these words have “ear”. Then ask students how to pronounce this group of letter. We will know it pronounce as /ir/.
    Step 3: practice
    Give students some other words with the group of letter “ear” and ask students to read them by groups. For example, a sentence “my dear, your tear is clear in my mind for years”. Then students can have a brainstorming and think of more words with “ear”.
    Play a game Hot potato to practice these words. The teacher plays a piece of music. When the music is playing, students pass the ball from one to another. When the music stops, the one who gets the ball should read words on the blackboard.
    Step4: Production
    Do a chant with students: put your ear, near my ear, and you will hear, and you will hear, and you will hear, NOTHING!
