A. Why Do We Teach Technical English?
1. Definition of EST
EST is the area of study of English for science and
technology. It emphasizes purposeful and
utilitarian learning of English. The communicative
needs of the learners are important consideration
of course design. EST is concerned with both the
oral and written discourse of English for academic
or professional, occupational or vocational
purposes. EST mainly deals with learners at the
tertiary level for whom the learning of English
takes on a service role for their specific needs in
study, work or research.

A. Why Do We Teach Technical English?
3. Reasons for teaching technical English
-Students are familiar with the subject content.
-The learning objectives meet students’
communicative needs.
-The materials and activities promote students’
learning motivation.
-Learning is purposeful and beneficial.

B. Syllabus Design
1. Register approach
2. Rhetorical approach
3. Skills-based approach
4. Content-based approach
5. Genre-based approach

Teaching Technical English

C. Materials Development
1. Procedure
(1) analyzing learner characteristics and learner
needs
(2) determining course objectives
(3) evaluating/selecting available materials
(4) deciding on an appropriate approach
(5) designing/adapting/producing materials
(6) testing materials
9

C. Materials Development
2. Adapting materials
(1) at lexical level

subject content: introducing advances in
microprocessor interfacing techniques
10
Teaching Technical English

(Original) A complete interface board is today shrunk
into a few LSI chips. The price paid, as in the case of
a microprocessor, is that the architecture is frozen
inside the LSI chip.

(Adapted) A complete interface board is today shrunk
into (today becomes as small as) a few LSI (Large
Scale Integration) chips. The price paid, as in the case
of a microprocessor, is that the structure of computer
components becomes fixed and can no longer be
changed.

C. Materials Development
2. Adapting materials
(2) at sentence level
Subject content: acid rain may harm people who
suffer from asthma, bronchitis, and heart
disease
12
Teaching Technical English

(Original) That scientists have developed little firm
evidence linking acid rain to human illness does not
prevent them from fearing that breathing acidic
pollutants can harm people who already suffer from
asthma, bronchitis, and heart disease.

(Adapted) Although scientists have not found much
evidence linking acid rain to human illness, they fear
that breathing acidic pollutants can harm people who
already suffer from asthma, bronchitis, and heart
disease.

2. Adapting materials
(3) at rhetorical level
Rhetorical purpose: introducing the rhetorical
structure of comparison and contrast
14
Teaching Technical English

(Original) Scientists at the Academy of Natural
Science in Philadelphia spread a film of No.2 fuel oil
over water and exposed it to light wavelengths similar
to those in the sun’s high-energy spectrum. They
found that light produced toxins that killed
microorganisms in the water. Oil kept in the dark
remained stable and had no apparent effect on the
organisms.
15
Teaching Technical English

(Adapted) Scientists at the Academy of Natural
Science in Philadelphia conducted two experiments
comparing oil exposed to light and oil kept in the
dark. They spread a film of No.2 fuel oil over water
and exposed it to light wavelengths similar to those in
the sun’s high-energy spectrum. It was found that light
produced toxins that killed microorganisms in the
water. By contrast, oil kept in the dark remained stable
and had no apparent effect on the organisms.

-incidental learning vs. explicit teaching
22
Teaching Technical English

Example: teaching compounds
compounds in the lesson:
adjective compounds -- low-cost design, highquality product, hand-held device
noun compounds -- design value, design options,
software design
23
Teaching Technical English
Example: teaching compounds
1. ask students to derive rules about the formation
of compounds by using examples in the lesson
2. use interesting examples to highlight key ideas
about compounds (e.g., bird house/house bird,
data test/test data, sleep-inducing drug/druginduced allergy)

5. Teaching grammar
-forms and functions of grammar
-special usages in technical or academic contexts
-sources of difficulties
25
Teaching Technical English

Example: teaching voice (I)
Compare the following pairs of sentences:
(1) People speak English in London.
(2) English is spoken in London.


Example: teaching voice (II)

A scanner moves along the printed text and photographs
the words. _____ The computer analyzes the signals
according to programmed rules for pronunciation, and
sends a command to a speech-producing device for coded
speech units.
(1) A minicomputer then converts the words into electronic
signals.
(2) The words are then converted into electronic signals by
a minicomputer.

Example: teaching voice (III)
A plant is a living organism. Different parts, each with
particular purposes or functions, make up the plant. Some
parts of the plant may be removed without harming it.
Food is stored in the roots of plants such as beets, carrots,
and potatoes. Other plants are able to take nitrogen from
the air and add it to the soil. Scientists call these plants
legumes. If they are plowed under, they make the soil more
fertile.

and then more rapidly, finally getting to a
plateau. (describing a graph)
