Question 7: "Why are Flowers So Red" Lesson Plan Lesson Plan Instructional Design Hello everyone! The article I am exchanging today is an illustrative essay genre titled Why Are Flowers So Red? Inappropriate places I implore you to correct.
1, the guiding ideology:
Language teaching should guide students to discover the rich world of language, in the world of language to discover the rich world of life, feel the rich world of emotions, in the process of discovery to improve their own language literacy and language skills. The theme of the fourth unit of this booklet is the illustration of things, which is intended to guide students to discover the magic of the scientific world and feel the charm of the combination of science and language, and the lesson "Why are the flowers so red?" is a good reflection of the theme of language discovery. I designed this lesson, trying to prompt students to change the way of learning, independent learning, discovering problems, exploring problems, solving problems, and cultivating the habit and ability of discovery.
2, the overall design intention:
The teaching object of this lesson for the seventh-grade students, from the beginning of the first year, I have focused on cultivating students two reading habits: one is to read the article closely around the writing of what how to write the two aspects of the two, and the second is to read a text, you must be on the content of the article or the expression of their own views or questions and written records. In the new classroom under the guidance of the concept of the new standards, they have a year of learning experience, the learning of the new curriculum is more familiar and adaptable, in the classroom has been independent, cooperative, exploratory learning experience, the classroom initiative is relatively good, know how to cooperate with others to learn, but also has a certain language literacy.
So I will teach this lesson in two lessons, the first lesson to guide the students to feel the charm of science, to cultivate the students of the article overall perception, understanding, the ability to understand, to solve the problem of what to write; the second lesson to learn the delicate structure and strict language, to solve the problem of how to write.
Teaching should closely follow the new standards, according to the students, the characteristics of the material to teach reading this article, in mobilizing students to think, discuss, and express themselves on their own, mobilizing the autonomy of the students, teachers are mainly inspired to guide the students, and vigorously advocate to the students to independent, cooperative, inquiry learning style, so that students are accustomed to this method of learning, and are accustomed to the combination of individual learning, cooperative learning, and inquiry learning. At the same time, in the classroom, teachers should be flexible in dealing with the relationship between multimedia and text, with multimedia vividness, image to attract students, better serve the students.
I think this lesson is long, to use half of the class time to consolidate stylistic knowledge, familiarize with the content of the text. In addition, because the text involves a wide range of knowledge, in explaining why the flowers are so red, the use of biochemistry, physics, plant physiology, evolutionary theory, natural selection and artificial selection, etc., to illustrate the matter of fact there is a certain depth, the students understand that there is a certain degree of difficulty. Therefore, in teaching, there is no need to explore in depth these very specialized knowledge, students know it can be. Otherwise, it will be noisy, the language of the classroom into another classroom.
