• Introductory sentence describing what the figure shows
 (now: 2000-2017; projection 2017-2030)
• Overall comments about the data in the figure, and theirconnection to
a real-world context
• Specific comments about the data in the figure, and theirconnection
to a real-world context
• Summary sentence
 What’s the future of nanotechnology like based on this barchart?

57. OVERALL TREND
The overall trend is a dramatic increase, with the size of the market
going up approximately twelvefold, from its 2000 starting point of
about $25 billion. This might be due to a rapidly expanding use of
nanotechnology in many different areas.

58. SPECIFIC TRENDS
Amongst the differently coloured sectors, the most noticeable
change is that more and more market sectors are projected to be
using nanotechnology, and the absolute value of the market share
of all of them will rise. This could be explained by the fact that as
the emerging technology becomes more mature, confidence in its
use will increase. However, it can also be noted that the dominant
sector within Japanese nanotechnology will continue to be
electronics. Probably, this is because of the miniaturisation that
tends to take place with technology concentrating on going down to
as small a level as possible, the nanoscale.

61. DATA ANALYSIS

67. ANALYSE QUALITATIVE DATA
In analysing the interview data, two themes emerged which will be discussed in this section. These
themes were: the complexity and challenges of working with families and the professional satisfaction
and challenges of program planning for children in preschool or childcare.
For each of these graduates, their work with children was clearly the area of their professional lives that
was bringing the most satisfaction, although there were some challenges identified. In the
interviews, the data reveal that they were all seeking ways to improve their pedagogy and achieving
success in different ways…
Angela suggested that in her second year of teaching she had changed in that she was programming in
a "more child oriented" way. She discussed this change:
One of the things I've changed is this idea of herding children through the kinder day: they go from indoor play to
snack time to the mat and so on. How I do it now is that I have a lot of different things happening at once. I'll have
a small group on the mat and there might be some children sitting down and having a snack and there's still some
children in home corner playing.
These comments seem to provide evidence that Angela is growing professionally for two reasons. First,
the ability to identify changes in her program suggests to me that she has deeper pedagogical
knowledge gained through critical reflection on her practice, and second, there is congruence between
her expressed beliefs and the practice she describes.

70. DISCUSS YOUR FINDINGS
RESEARCH QUESTION
•Do your research findings support your initial hypothesis? Why
and how?
•Do your findings only support the hypothesis in part? Why and
how?
•Do your findings disprove your hypothesis? Why and how?
•What else do your findings tell you, over and above what you
initially set out to investigate?

71. DISCUSS YOUR FINDINGS
WRITING YOUR DISCUSSION
•Which has been done by other people
•Which has been done by you
•And how they complement each other
•Point out the agreements and disagreements between your data
and that of others.

72. VERB TENSES FOR DATA

73. When to use Tense example
Location element Present tense • The averaged results are presented in table
6.1
• Table 5 shows
Summary of
procedure
Past tense The influents to filter A and Bwere analysed
fully on a number of occasions, …
Results of analysis
(analytical process)
Past tense The ranges of metal atom concentrations…
were found to overlap.
Describe your
finding
Present tense • My data shows
• This study shows
• The findings of this research indicates
Your own analysis of
the data
Present tense This discrepancy can be attributed to the small
sample size.
Make reference to
similarities or
differences in
approach or findings
Past tense • However, Smith and Geva found that…
• A previous study in Belgrade also found

• Similar research carried out in the 1930s
showed that
Compare your

research
Use the present perfect tense
to highlight the recent
relevance of your research in
comparison with earlier
research referring to it in the
simple past.
This study has shown a prevalence rate of 2.5
which is greater than that found by Smith and
Geva in their Belgrade study…

74. USING CAUTIOUS LANGUAGE
AS A RESEARCHER, YOU ARE EXPECTED TO DISTINGUISH
CAREFULLY BETWEEN:
•Knowledge you are sure of because you have reliable evidence
for it
•Other knowledge you are less sure of
•Other knowledge you think is only within the realms of possibility
Therefore, very strong claims, like the one below, are rare in
academic writing
•Reducing fat intake lowers the risk of heart disease.

75. INDICATE THE DEGREE OF
PROBABILITY (NOTE HOW THE CLAIM
PROGRESSIVELY WEAKENS):
• It is certain that
• It is very probable/highly likely that
• It is likely that
• It is possible that
• It is unlikely that
→ Reducing fat intake lowers the risk of heart disease.

76. INDICATE THE DEGREE OF
PROBABILITY (NOTE HOW THE CLAIM
PROGRESSIVELY WEAKENS):
• Reducing fat intake lowers the risk of heart disease.
• Reducing fat intake could/might lower the risk of heart disease.
• Reducing fat intake may lower the risk of heart disease.

77. DISTANCE YOURSELF FROM THE
CLAIM:
• Reducing fat intake appears to lower the risk of heart disease.
• It seems that reducing fat intake lowers the risk of heart disease.
• Some researchers suggest that reducing fat intake lowers the risk
of heart disease.

78. DISTANCE YOURSELF FROM THE
DATA, BY SHOWING ITS
LIMITATIONS:
• Some studies indicate that reducing fat intake lowers the risk of
heart disease.
• Forthis age group , reducing fat intake lowers the risk of heart
disease.
• In most of the cases studied , reducing fat intake lowered the risk
of heart disease.

79. USE A QUALIFYING VERB:
• Reducing fat intake tends to lower the risk of heart disease.
• Reducing fat intake contributes to lowering the risk of heart
disease.

80. IN PRACTICE, A COMBINATION OF
THESE METHODS IS OFTEN
USED:
• The majority of studies indicate that for this age group, reducing
fat intake contributes to lowering the risk of heart disease.
