| Informatics for Secondary Education - A Curriculum for Schools (ED/HEP - pii-iip - IFIP - UNESCO, 1994, 103 p.) |
Informatics can be of considerable value in the teaching of many subjects of the normal curriculum at the foundation and advanced levels. This section gives examples which teachers will wish to use themselves or when promoting informatics more generally with other teaching colleagues. Students will also find these examples a stimulant to their own work in other subjects as well as an enrichment of their informatics studies.
Teachers may find that by integrating the use of computers within subject areas, most of the Computer Literacy objectives can be met without the need for a separate course.
Students of the Advanced Level Unit GA3: Applications of Modelling, will find that earlier experience of using computers in other disciplines provides a good background to their work, as well as good starting points for more advanced subject oriented modelling techniques.
NATURAL SCIENCES
Text Processing
Students can use a word-processor to
type their reports of experiments and research.
Desk Top Publishing (DTP)
Students can use DTP to
produce attractive looking documents, especially those requiring a combination
of text and graphics.
Graphics
Students can use graphics software to prepare
illustrations, with or without labels, which can later be imported into DTP
documents; or which can replace the usual method of preparing hand-drawings.
Spreadsheets
Students can use spreadsheets to tabulate
and calculate results of experiments; or for manipulation of variables to see
certain effects that can be more clearly and quickly demonstrated with the use
of spreadsheets. Students can also request various types of charts to be plotted
from values entered into a spreadsheet.
Teachers could prepare templates to assist students new to spreadsheets; or prepare spreadsheets which have values already entered in order to illustrate effects from the manipulation of variables which is appropriate for work on simulation and modelling.
Databases
Students can create databases such as the
characteristics of chemical elements in the periodic table, characteristics of
plants, insects, and mammals; and interrogate these databases to find
relationships and commonalities. As a first step, teachers could prepare
databases into which students can add data.
Robots and Feedback Devices
Students can build robots
and use robotics to perform experiments, particularly in physics.
Using mechanical, temperature and other probes to monitor experiments, and feeding the readings directly into a spreadsheet, helps to obtain more reliable results and makes classroom work more realistic. Several software tools exist which take readings, interpret them and present them graphically.
Communication
Students can use computers to
communicate with other students on a local network, or with students in other
schools both locally and overseas. This enables data to be gathered and shared
with others, for example rainfall and Ph values in different countries or
particulars of insects unique to a region.
Speech Recognition
In Physics and at times in Biology,
students can use external devices to record sounds, and use computer analysis to
study sound waves and patterns .
Expert Systems
Expert systems written by students may
be of little value but students learn so much from writing such a system that it
should be attempted wherever resources are available. One expert system well
within the scope of advanced students predicts the result when two chemical
elements are mixed.
Modelling and Simulation
The "Three-mile Island"
disaster can be simulated in every classroom without any danger to students.
Even when students have performed or withnessed a demonstration, repeating the
experience through modelling often gives them further insights.
Presentation Software
Students can use presentation
software to generate slide presentations of their projects, experiments and
research findings to large groups in class.
MATHEMATICS
Spreadsheets
From doing repetitive calculations to
showing patterns in certain number manipulations, spreadsheets can play an
important role in mathematics at most levels.
Graphics
Specialised graphics packages are available
which show the graphical representation of any given function. Also there are
software packages which allow geometry problems to be presented on video screen.
Statistics
Using suitable software tools takes the
pain of hours of calculation out of statistics and provides important analyses.
The complications of manual calculation often make real-world examples too
difficult to handle; with a computer, realistic situations can be analysed more
readily.
Computer Assisted Design (CAD)
Some CAD packages can
be used in some aspects of geometry as substitutes for graphics packages.
Modelling and Simulation
Students can use simple
modelling packages, such as Mathematica, to gain insight into mathematical
functions.
LANGUAGES
Text Processing
The most common use is to create
letters and others documents.
Teachers or students can create Close reading texts, texts with missing words and texts that need punctuation, plural or another tense. Arranging a story in chronological order, or completing a story or an outline are other valuable applications.
Desk Top Publishing (DTP)
Apart from creating
newsletters, newspapers and posters, students are extremely fond of using
available graphics to create attractive documents.
Graphics
Being able to illustrate what they produce
gives students an impetus to write. Students will appreciate ready-to-use
graphics, and the high quality graphics they can create themselves. Some
programs combine the power of a simple DTP package with sophisticated graphics.
Robotics
For students the control of a robot through
commands in a foreign tongue is often a most satisfying task even with a
limitated vocabulary. For example, Logo is available in English, French,
Spanish, Greek, German and a number of other languages.
Communication
Nothing seems to be more motivating for
some students as communicating with a native speaker of a foreign language in a
distant country. The availability of e-mail, bulletin boards and computer
conferencing has made instant communication possible. However, communication by
(posted) disk and word-processor document should not be ignored.
Speech Recognition and Synthesis
Given the right
software, students can compare their own pronunciation with that of the
synthesised model, both oral and visual.
Expert Systems
Given the correct tools, students can
write programs which use the rules of an expert system language or manipulate
the language. For example, a simple expert system could he written to change
English nouns from singular to plural.
Programming
Given a suitable language (Logo, Boxer,
Lisp, Smalltalk) students can easily write their own expert systems as indicated
above.
"OUTSIDE BACK COVER" - AN ENCOURAGEMENT TO READING
This is an example of an inter-disciplinary project which helps to meet some of the Computer Literacy objectives and links students and teachers in school with information scientists and librarians.
The Project
Students write a "fourth outside back
cover" which is a summary of a book recently read with the purpose of giving
others the longing to read it (this is not a matter of marketing!).
Typing the Summary
Students use a word-processor to
prepare the text, adding personal information about themselves, their class and
their school, as well as keywords, ISBN number and an abstract which could be
used by school or local libraries. A complementary activity could be a book of
the month selection.
Database Creation
Students collect contributions from
other students in the same or different classes or schools within their region
to create a database of reviewed books.
Database Use
Students interrogate the database for
their next reading choice, to get or order a book from the librarian, or to link
with the database of the school documentation center.
SOCIAL SCIENCES
Text Processing
Any subject requiring reports, essays
and other documents can make good use of a word-processor, a graphics package
and desk top publishing software. Advanced students will be able to draw on
variety of information sources to prepare multimedia presentations.
Spreadsheets and Databases
In the study of social
sciences, spreadsheets and databases serve the same purpose: to enable students
to systematise and organise information. For example, students could make use a
spreadsheet to make a list of dates, events, countries and persons involved.
This list could then be organised by date, by country or by the person's name.
Such lists make good study aids. Younger students like to collect information,
and will enjoy setting up a database, for example on facts about all EEC
countries.
Communication
Students can use e-mail and disk mail to
communicate with residents of places of historical or geographic significance.
Statistics
Especially when studying Geography at an
advanced level, students may need to use a statistical package.
Expert Systems
Students of Geography could write
expert systems on such mailers as the conditions needed for a village to be
established and to flourish as a regional trade center.
ART
Graphics
Some graphics packages allow for the creation
of original artwork. However, art teachers are more interested in the way in
which they can create patterns, complementary patterns and patterns with
variety. For example in textile design, computers enable students to see an
overall result with less effort than by any other method.
Desk Top Publishing (DTP)
In the design of posters and
other printed matter, using DTP ensures a professional product in minimum time,
with the option to re-use or modify a design at will.
Programming
Programming languages with a graphics
interface, such as Logo, allow for the creation of intricate patterns with
minimum of effort. The graphics part of such a language should be included in
design courses.
