3
and math are known as STEM classes.

Many professors continue to teach STEM classes the traditional way, by lecturing.
5
But standing in front of the class and lecturing may not be the best way to teach today's students.

背景与背景信息
在当前的教育体系中，科学、技术、工程和数学（STEM）课程通常依然以传统的讲授方式进行教学。加州大学洛杉矶分校的凯文·埃根（Kevin Egan）指出，这种教学方法虽然并非坏事，但如果仅仅依靠讲授，则其效果可能会大打折扣。研究表明，学生在参与课堂讨论、提问及动手活动时，学习动机和参与感会显著增强。这提醒我们，教育工作者需要调整教学方式，使得学生能够更主动地参与学习过程，尤其是在如数学和科学这类内容复杂的学科中。
日常交流的五个常用短语
- I have a question.（我有一个问题。）
- Can you explain that again?（您可以再解释一下吗？）
- Let’s work on this together.（让我们一起解决这个问题。）
- What do you think about this?（您对此怎么看？）
- I prefer cooperative learning.（我更喜欢合作学习。）
这些短语不仅在课堂上，日常沟通中同样适用，可以帮助你提高英语口语练习的流利度和自信心。
逐步影子练习指南
为提升你的英语发音和口语表达能力，特别推荐使用“shadowspeak”或“shadow speech”技术。以下是一个逐步指南，帮助你克服视频中难度较高的部分：
- 选择片段：从视频中挑选一小段，长度可以在30秒到1分钟之间。
- 仔细听：多次听这段音频，专注于讲者的发音、语调和语速。
- 分段模仿：尝试逐句模仿讲者的语音，注意每一个音节，尤其是重点词汇。可以使用“提高英语发音”作为你的练习目标。
- 录音对比：录下自己的模仿，再回去与原音频进行对比，注意差异。
- 反复练习：坚持每天练习，逐步提高你在“雅思口语练习”中的表现和自信度。
通过这种逐步“影子练习”的方法，你不仅能增强对英文口语的理解，还能逐渐增加你的实际应用能力。从而在任何学术领域获得成功。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
