一、实验介绍

本学校本学期高一年级开始使用进口教材《Solutions Intermediate》为了实验学生是否能拿下里面众多的生词，特此设计了本教案，并将两个班级进行对比分析。

实验内容为《Solutions Intermediate》Unit 1A Vocabulary and Listening

实验对象为高一年级两个相同人数的班，实验班和对照班。

二、实验和课程设计及反馈

Pre-class task：

Students are required to use casino to self-study exercise 1 and 2. Find out the meaning for those new words both in Chinese and English.

注：这个部分在对照班没有布置，仅实验班学生做，他们运用卡西欧辞典查出单词并放入卡西欧学习簿的单词本中，方便上课随时调用。

Teaching design

Step one：（warm-up questions）

1. What kind of clothes do you like wearing？

2. What do you wear when you are taking part in the flag-raising ceremony every Monday morning？Do you like it？

3. Work in pairs，and describe the worst dressed person you once saw. Be sure to use your newly learned words as much as possible.

Step two：（Exercise 1&2）

Look at the pictures，these are Hollywoods worst-dressed celebrities，can you use the adjectives in exercise 1 and 2 to describe them？

注：在描述前，實验班仅用英文解释来检查他们对生词的掌握，卡西欧的学习簿也可以随时查用，对照班教师课堂上直接口头给出生词解释。

对照班完成任务明显耗时较实验班长。

Step three：（Exercise 3&4）

1. Listen to the radio show. Which two celebrities in the photos are described？

注：由于对第一题第二题单词熟悉程度不一样，实验班的学生由于单词定位速度更快地找到四个人中的两个人。

2. Take down notes about those descriptive words or phrases.

3. Use your note to finish Exercise 4.

注：本部分两个班在用时和准确率上无差异。

Step four：（Exercise 5）

Use your notes and Exercise 4 to figure out the rules of using adjectives before noun.

Opinion-size，length，or shape-texture-pattern or color-material

Step five：（in-class learning output）

Speaking：work in pairs and describe the most beautifully dressed person you once saw. Be sure to use your newly learned words as much as possible.

三、词汇习得检查

词汇习得检查结果如下：

四、实验结果分析

实验班虽然和对照班在词汇习得检测的差距不算很大， 稍稍好一点点（P<0.04），但是在课堂词语运用表现上明显好过对照班，课前运用卡西欧学习单词，对课堂词汇识记效率有明显的帮助。所以总体看来，课前运用电子词典对英语课堂教学是有好处的。
