4. Why?
Scientific writing is the culmination or end product of
scientific research. Scientists pose questions and then
perform experiments to answer their questions. The
results that come from experimentation must finally
be presented to the rest of the scientific community in
the form of a published paper in a primary journal
before the research is considered finished.
5. Main Point
Writing an effective scientific paper is not easy. A
good rule of thumb is to write as if your paper will
be read by a person who knows about the field in
general but does not already know what you did.
Before you write a scientific paper it is a good idea
to read some scientific papers in the format of the
paper you will use. In addition to the science, pay
attention to the writing style and format.
6. Example (1)
q An evaluation of the program by us will
encourage increase in efficiency in the
servicing of clients.
q We will evaluate the program so that we can
serve our clients more efficiently.
7. Example (2)
q The design of the experiment, in terms of the
establishment of a clear control and the practicability of
timing the reactions precisely, although compensations
were included to address these factors, was not
successful.
q The design of the experiment was not entirely
successful, because the failure to establish a clear
control and time reactions precisely, although
compensation were included to address these factors.

(IMRAD)
Introduction
2. Presents clearly the background and scope of a
problem
3. Review pertinent literature
4. Presents the investigation method
5. Lists principal findings
6. Summarizes main conclusions
12. Additional Tips
1. Move from general to specific
2. Engage your reader
3. Make clear the links
4. Be selective
5. Ask your instructor
13. Additional Tips
This study investigates the relationship between
tree density and fruit size.
The purpose of this study is to determine the effect
of enzyme concentration on the reaction rate of ....
14. Additional Tips
The hypothesis is the explanation you are proposing
for certain observations. It is a tentative answer to the
question you have posed above. It should be
accompanied by a prediction of results expected
under certain conditions if the hypothesis is correct.
If competition lowers reproductive output, then fruit
size should be smaller when tree density increases.
15. Materials and Methods
– Describes exactly materials, quantity, and sources
– Makes possible repetition of experiment
– Describes clearly the experimental design
– Uses past tense
– Gives references for methods used
– States the statistical analysis
16. Additional Tips

19. Results
q 1. Explain why each procedure was done, i.e., what variable were you measuring and why? Example:
Difficult to understand: First, I removed the frog muscle and then I poured Ringer’s solution on it.
Next, I attached it to the kymograph.
Improved: I removed the frog muscle and poured Ringer’s solution on it to prevent it from drying out. I then
attached the muscle to the kymograph in order to determine the minimum voltage required for contraction.
q 2. Experimental procedures and results are narrated in the past tense (what you did, what you found, etc.) whereas
conclusions from your results are given in the present tense.
q 3. Mathematical equations and statistical tests are considered mathematical methods and should be described in this
section along with the actual experimental work.
q 4. Use active rather than passive voice when possible. Always use the singular "I" rather than the plural "we" when
you are the only author of the paper. Throughout the paper, avoid contractions, e.g. did not vs. didn’t.
q 5. If any of your methods is fully described in a previous publication (yours or someone else’s), you can cite that
instead of describing the procedure again.
20. Right and Wrong
q NO: Dissolved oxygen results are shown in Table 1.
q YES: Table 1 shows that dissolved oxygen
concentrations ranged from 14 ppm to 9 ppm.
q NO: Figure 1 shows the relationship between water
depth and dissolved oxygen concentration.
q YES: As shown in Figure 1, dissolved oxygen
concentration decreases with depth.
21. Right and Wrong
q NO: The geologic cross section shows the makeup of the
subsurface.
q YES: The geologic cross section illustrates that the
subsurface consists of sand and gravel with some clay
lenses.
q NO: The geologic cross-section shows that groundwater
can travel quickly through the subsurface. (discussion).
22. Additional Tips
1. Order: from most to least important, from
simple to complex, organ by organ
2. Use past tense
3. Don’t simply repeat table data
4. Don’t interpret results
5. Avoid extra words
23. Discussion
1. Principles, patterns, relationships, generalizations
2. Exceptions and unsettled points
3. Results compared with previous work
4. Implications, applications, beneficiaries
5. Clear conclusions
6. Evidence summarized for each conclusion
7. Possible future research arising, if any
24. Additional Tips
1. Move from specific to general
2. Don’t bury or ignore the major issue
3. Make explanations complete
• Don’t overgeneralize
• Don’t ignore deviations in your data
• Avoid speculation that can not be tested in the
foreseeable future
25. Examples
•NO: The groundwater is getting cleaner.
YES: On February 12, 1990 the monitoring well contained
23,000 ppb of dissolved hydrocarbons; while on September
16, 1996 the same well contained only 87 ppb. This indicates
the groundwater is getting cleaner.
•NO: The lake is not in danger of becoming acidified.
YES: An alkalinity of 140 ppm helps to prevent the lake from
becoming acidified.

36. This is a brief synopsis of the paper so that the reader can get the point
and decide whether to read the entire paper. Abstracts are typically
included along with titles in bibliographic sources such as the ones
you use in on-line searches. In about 100 or 200 words, an abstract
summarizes the purpose of the study or question investigated, the
method used, the major results, and the conclusions drawn from the
study. It is good practice to write the abstract last, even though it
appears at the beginning.

q A fascinating book written by Mr. Wang will be coming
out soon. This epic book vividly portrays the life of a
penniless family with five brothers to go into the army to
combat with the fully armed inhuman Japanese invaders,
taking place in the 1930’s in the northern China plains.
After I skimmed through the sample copy in which Mr.
Wang inscribed his name, I was immediately engrossed
in it. This book should be a highly recommended must
read for all Chinese people who want to recall that
bloody war between the brave Shandong people and the
brutal Japanese aggressors.
