设计教师：深圳市龙华中学张兆玉教学年级：高二课题名称：Unit3 Inventors and Inventions—The problem of the snakes 教材版本：NSEFC BOOK8授课时间：40分钟（Ⅰ）Syllabuses ObjectivesIt is required in the New Syllabuses that senior students should develop reading skills to read for information, to read for language knowledge and to read for pleasure. Senior Two students are supposed to achieve 8-graded objectives in the aspect of reading skills proposed in the New Syllabuses.（Ⅱ）Target materialWith the development of science and technology today, a variety of inventions and creations have come out from every aspect of our life. The thinking qualities and patterns of a person play an important role in his or her lifelong development. That’s why modern education needs to develop the learner’s creative thinking.The unit theme is about “Inventors and Inventions”, which covers “the difference between ‘Invention’ and ‘Discovery’”, “the stages in producing an invention” and “the patent application criteria.The 3A (“Awareness-Autonomy-Authenticity) teaching principle is embodied in the teaching design. The teacher is to help the students express their own ideas and opinions about a creative smart thing, and describe an invention.(Ⅲ) Academic levelSenior Two students, active in thinking and curious about everything, have already got lot of knowledge in science and technology from their science subjects. They are very familiar with the topic. They have the ability to communicate with each other about the target material, but they still have some difficulty expressing their own thoughts and describing an invention. Therefore, I can stimulate the Ss’ interest in this topic, and they will be motivated to accept the challenge to learn and use language to achieve these goals.The core task in this lesson is to read the passage “The Problem of the Snakes”. I ask the students to collect from the Internet some information about “inventions” before this lesson as a pre-lesson activity.（Ⅳ）Teaching objectivesLanguage-knowledge：1) To grasp the general idea and specific details of this text.2) To familiarize the Ss with the use of the past participle3) New words and expressions in the text.Language skills：Reading skills including the following and also follow on activities for speaking and writing about an invention.1)To develop the ability of reading for specific details.2)To grasp the logic links between paragraphs of the text.3)To learn to guess meanings in context.Learning Strategies：Cooperative learning by means of pair or group work.Affective objectives:Students are challenged to think creatively，to identify the difference between discovery and invention, and to experience the enjoyment in making an invention.Cultural awareness：To challenge the students to solve a real-life problem and share experiences with others in the process.To learn to be imaginative and creative.（Ⅴ）Teaching Strategies:Teaching approaches:1)The Communicative Approach: This lesson contains activitieswhere learners communicate and where tasks are completed by meansof interaction with other learners. There is extensive use of pair,group and mingling activities, with the emphasis on completing thetask successfully through communication with others.2)The Task- based Approach: I offer the student opportunities todo something—to acquire information and knowledge, to processinformation and to apply knowledge to solve an authentic problem.In this lesson I create a need to learn and use language. Studentsare assigned several tasks to complete in order to achieve aspecific outcome.Learning Strategies:Language is acquired as learners actively engaged in attempting to communicate in the target language. All the activities I designed are intended to provide various personalities opportunities to do things actively and to motivate students to fulfill their potential to achieve the goals by using English in a communicative classroom.That’s what the Learning-by-doing principle requires.Teaching Aids:Stud ents’ worksheet, a projector and a multimedia computer（Ⅶ）Post-lesson ReflectionIn principle, I adapt communicative and task- based approaches in this lesson. All the activities that focus on one main target are organized in a task-cycle with an outcome--- following the stages mentioned in the text to solve a real-world problem. The task cycle consists of a seriesof minor tasks, each of which serves one primary focus on enabling the learner to reach higher and higher levels of communicative performance. Consequently, students from different English levels can participate in the classroom activities all the way, and so they are challenged to achieve the main goal I set for them by means of different leaning strategies. That’s just what we teachers should take into consideration when we design our classroom teaching.1)The tasks set in a meaningful communicative classroom enable thestudents to process language which is being learned or recycled more naturally.2)The computer-assisted teaching aids contribute to improving theefficiency this lesson, by increasing the input of information.3)The post-reading task provides the students an opportunity to solvea problem in an authentic situation and use what they have learned todo something by communicating with others4)All the activities, arranged in the pattern: inputting information—processing information—outputting information, are meant tostrengthen the integrated skills.附学生课堂活动工作单：（Students’ worksheet）:Task oneA discovery is____________________________________________________________________ .An invention is___________________________________________________________________.
