Population Pyramids enhance the integration of
language and content in speaking and writing
Demography is an interdisciplinary field, which
is central to different degree programs such as finance, government,
International Relations and Economics to mention a few. When population
pyramids and diagrams are used in the EFL course, they are meaningful because
they conjure content material from the student’s area of study. Furthermore, a
range of language related to addressing present, past and future are used by
students as they look at population pyramids.
This is part of an ongoing class project, which
students have found interesting and useful as they have been able to put their
academic skills to practice. Furthermore, students realize the importance of transcending
the disciplines in order to provide a complete explanation for the demographic
trends and transformations.
Population Pyramids present the size of a
female and male population of a given area by age groups or cohorts by 5 year
intervals as can be seen in this pyramid of the world’s population profile for
2017
The website, https://www.populationpyramid.net/
presents population pyramids at a global, regional, continental and national
level. The user can look at pyramids for a place from the past, predictions for
the future. Dr. Martin De Wulf, the owner of the site, happily guaranteed the right to
copy graphs for academic purposes. This would enable students to use them for
slides or poster sessions to discuss and analyze population changes.
Talking about the past
As students compare the size of a certain age group
to another, they can develop language related to speculation such as models.
Irregular patterns in pyramids, such as certain disproportionally large or
small cohort triggers an interest the factors contributing to this phenomena.
It here that knowledge from mainstream courses such as history, current
affairs, sociology and others comes to use in student discussions. For example,
this pyramid of Oman brought up the issue of migrant workers as there cohort
for males aged 30-34 does not conform to that of most countries. Students who
have been studying migration suspect the presence of a large migrant labor
force given the age. Moreover, questions about the factors that pull them there
and their place of origin arise, Comparatives and superlatives come in useful
as students look at the cohort in light of its female counterpart.
Discussions about the future of a country in
terms of its working population and pension system are also triggered. Again,
in terms of language, it’s yet another opportunity for practicing modals. Also,
future conditionals can be practiced as students who have taken actuarial
science courses predict what would happen to the pension system as in the case
of Denmark.
Conclusions
Students simultaneously practice language and
content skills. Content knowledge is constantly constructed as students
reach into the different disciplines to explain the nature of a cohort in its
present, past and future forms. Students always ask to look at different
countries and also learn about countries they would never probably never have
studied. From a language perspective, they subconsciously drill grammar forms
as they speculate and compare cohorts and countries. Not much research has been conducted on the
dual learning that occurs through population pyramids in the classroom, making
them an interesting tool for areas such as PBL and CLIL.
