Information is power
Francis Bacon
What we need today is not more power,
but rather the power to manage the information that we have.
Norton/Wiburg
We are living in an age where the currency and product of much of
what we do is information. The information explosion that we must
face is staggering in its proportions. Not only is the amount of information
a cause for concern among educators, but the means to access and use
that information is changing as well. Rather than focus our attention
on the futile task of keeping up with the amount of information, shouldn't
our goal be to give our students the skills with which they can access
and manipulate the data? This lesson plan is designed to explore the
on-line database as a means of finding and gathering meaningful data
and to enhance the communication skills our students will need to
be successful lifelong learners.
In the initial phase of the lesson, the students were given the task
of choosing companies that traded stock on the New York Stock Exchange,
locating information about those companies and making investment decisions
based on the information they could obtain. Rather than simply giving
the students that information, it is necessary to provide the tools
they need to search for the data on which to base their plans. These
search skills are readily transferable to all other curricular areas
and will form the basis of an improved ability to deal with the information
'overload'. Students are given the opportunity to design a strategy
for searching based on criteria that is at first teacher directed
and then augmented and extended by group deliberation.
Once the companies have been decided upon and investments made, the
students are then instructed to track the daily performance of their
stocks using an on-line database. (www.nasdaq.com).This gave
the students the opportunity to experience and exploit one of the
unique characteristics of the Internet - its currency. The ability
to immediately distribute information world-wide allows us to stay
up-to-the-minute on the information that we need. In dealing with
financial matters, this immediate information is critical. Fluctuations
in the stock market minute-by-minute can have a profound impact on
investment strategies. The use of an on-line database allows students
to literally witness those fluctuations as they occur and analyze
the effects on their investments. Utilizing the Internet to stay abreast
of ever-changing events is vital in almost all areas of learning.
Accessing the Nasdaq web site, the students are presented with a
large amount and wide variety of information. Given the structure
of the lesson plan and the goals for investing set forth by the instructor,
it is up to the students to decide on the types of information that
will be valuable to them. One of the most discouraging aspects of
using the Internet, or a database, is the overabundance of information
that is presented. However, it is up to educators to give the students
the skills needed to evaluate the information as to its relevance
and quality. Norton & Wiburg, in Teaching with Technology, write,
"...effective sorters must be able to determine which parts of
the remaining information are important and which parts are superfluous.
In a world producing information faster than it can be sorted, deciding
what not to attend to becomes as important as deciding what to attend
to."
Simply being able to find and collect information is not enough.
The students must synthesize the information that they have collected
and communicate that information in a meaningful way. Students today
must have the ability to take information and create effective presentations
of that information. Graphical representations of numerical data is
superior to tables because of what Donald Norman calls the "Perceptual
Principal". In Things That Make Us Smart, he writes, "Perceptual
and spatial representations are more natural and therefore to be preferred
over nonperceptual, nonspatial representations..." Encouraging
students to use the spreadsheet graphing functions gives them the
tools by which they can effectively relate to others their experiences
in working with the stock market. Students are able to demonstrate
the performance of various stocks, as well as the resulting profits
and losses in a way that is easily understood.
In preparing today's students for the future, schools must recognize
that the model of teacher-as-infomation-provider will not be adequate.
There is simply too much information to impart in the time allowed,
and the volume is growing every day. In order to allow our students
to become independent, life-long learners we must move beyond the
traditional concept of literacy and provide them with what Paul Gilster
calls Digital Literacy. In his book Digital Literacy, he defines
this as "...the ability to understand and use information in
multiple formats from a wide variety of sources when it is presented
via computers." Today's literate student is one who possesses
the skills needed to search for information efficiently; evaluate
the information to sort between the valuable and the irrelevant; create
a product using the information and; finally, communicate that information
in a way that is understandable and meaningful.
