在这个对话中，三个学生（Lee, Peter,
and Jana）谈到科技工数教育。
Peter: I still
want to teach younger students, but I’ve decided that I also want
to teach STEM-related
subjects.
Lee:
STEM, as in science, technology, engineering and math?
Peter:
Exactly. Scientific and technological
innovations are really important these
days. And students need to be exposed to
STEM subject
matter as early as possible. And in a fun
way!
Jana: As an engineering
major, I couldn’t agree more.
It’s important to teach students what they can do with their
knowledge. I get to think up complex
ideas, but I also get to design them and sometimes build
them.
Lee: I
totally agree. I can’t wait for others to solve global
environmental issues. In my environmental science classes, we learn
how
to gather and evaluate
evidence,
beinnovative and develop
solutions to global issues.
Peter: Those are the
skills I want to teach my students one day! I think STEM education
is linked to a country’s
future prosperity.

“日常会话”由美国国务院教育与文化事务局英语语言项目处（Office of English Language
Programs, Bureau of Educational and Cultural
Affairs）资深项目官员海蒂·豪兰（Heidi
Howland）编写。
Six
students from around the world meet. What do they have in common?
They are all exchange students studying at a U.S. university for a
semester. Throughout the semester, they learn more English, learn
about U.S. culture, and learn more about their fields of study.
This series of Everyday
Conversations is about these six students and
their experiences during a semester at a university in the U.S.
These conversations are for intermediate-level English-language
learners or higher.

In this conversation,
students (Lee, Peter,
and Jana)
discuss STEM education.
Peter: I still
want to teach younger students, but I’ve decided that I also want
to teach STEM-related
subjects.
Lee:

Peter:
Exactly. Scientific and technological
innovations are really important these

Now let’s review the vocabulary.
STEM is an acronym for “science,
technology, engineering and math.”
An innovation is
a new idea, new thing or new way of doing something.
Scientific innovations are new
ideas, new things or new ways of doing something related to the
fields of science, such as biology, chemistry or
physics. Technological
innovations are new ideas, new things or
new ways of doing something related to technology.
In this context, subject
matter means the information or topic
taught in school.
The phrase “couldn’t agree more” is used to
emphasize that one completely agrees with something a person
says.
To think
up something is to invent or imagine
something.
Complex means made of a lot of
different parts, difficult to understand, not simple.
To gather
evidence means to find and collect
different reasons something may or may not be true. After gathering
evidence, one
can evaluate it.
This means to form an opinion about the value or quality of it.
Innovative means having new ideas
or ways of doing things.
Prosperity is the state of being
successful, especially in making money.
