高一英语（外研版2019必修第一册）
课题主题 | Word Formation （构词法） | |
教材分析 | 本课选自2019版外研社高中英语教材必修一Unit 2 Exploring English 的Using Language 部分。课本上该部分比较简洁，只简单地列举了四种构词法，没有详细的讲解，所以制作本微课作为课堂中讲解的辅助资源，让学生对构词法掌握更清晰。 | |
学情分析 | 本微课的授课对象是高一学生，英语水平中等，平时英语学习中的两大难题是记忆单词困难以及在阅读中遇到生词不会根据构词法或语境进行词意推测。构词法能在很大程度上解决学生的这两个问题，提高英语学习效率。 | |
课标要求 | 1. 了解词汇的词根、词缀；掌握词性变化规律，并用于理解和表达； 2. 运用构词法知识，扩大词汇量深度、学习词语，在表达各种信息时提高词语使用的准确性和丰富性。 | |
教学目标 | 学完本微课后，学生能够： 1. 掌握四种常见构词方法的定义和用法； 2. 运用构词法帮助记忆词汇，提高学习效率； 3. 运用构词法结合语境推测语篇中的生词，提高理解的准确性。 | |
教学步骤 | ||
内容设计 | 设计意图 | |
1. Lead in The teacher use two questions to lead in the topic “word formation”. 1) Do you have difficulties in memorizing new words？ 2) Do you worry about that the unfamiliar words in a reading passage might affect your understanding? | 用学生英语学习中面临的真实问题激发学生学习兴趣，引入话题。 | |
2. Activate background knowledge Ask Ss what they know about word formation? | 激活学生背景知识，确定教学起点。 | |
3. Think and learn Mainly use the inductive method to lead Ss to find out different types of word formation. (1) Ss look at some familiar words such as bookstore, everywhere, weekend and sunset and analyze how these words are formed to elicit the first type of word formation: compounding. (2) Ss analyze the different parts of speech of the same words and realize the fact that the same words can mean differently when we change their part of speech, which elicit the second way of word formation: conversion. a) Our classroom is very clean. b) We clean our classroom every day. (3) Use the network buzzword “YYDS”, which is very familiar to the Ss, to lead in this part. Ss think about what “VIP”, “DIY”, “NBA” stand for to understand the third type of word formation: abbreviating. (4) Guide Ss to think about the usage of prefix and suffix with the example of “like, dislike, unlike, unlikely, likely and likeness”. Explain the functions of prefix and suffix.
|
以归纳法为主，发挥学生学习主体作用，从熟悉的词汇中分析归纳出四种构词法类型。 | |
4. Summarize Guide Ss to summarize the four types of word formation and stress its benefits for word memorizing, word guessing and English learning in general. |
回顾总结，联系学习实际，提高学生学习技巧和运用所学解决实际困难的意识。 | |
5. Exercise Ss finish the exercises on the handout to practice four ways of word formation and consolidate their understanding. | 通过练习内化学生所学的构词法知识，巩固新知。 | |
