2 WEB 2.0 AND LEARNING
INFRASTRUCTURES
Since the introduction of the personal computer,
there have been many advocates working on using
computers to deliver learning materials. There have
also been, of course, people who have critically
commented on the lack of tangible results associated
with the introduction of computers in the classroom.
For instance, one article published by Oppenheimer
(1997), “The Computer Delusion,” sent a strong
message regarding the lack of accountability of
many projects using computers in classrooms in the
US. Also, Katz (1999) argues that today‟s colleges
and universities are faced with an environment in
which information technologies are rapidly
becoming the preferred mode of instruction to a
point that institutions cannot rely on traditional
methods to survive and prosper. Knowledge and
learning assisted by an organizational learning
infrastructure is not only about technology, it is
about culture, policies, processes, procedures, tools,
templates, incentives, etc. These infrastructures
include courses, communities, assessing the current
state of the technology, identifying long-term goals,
establishing metrics, prioritizing short-, medium-,
and long-term goals, and assessing them regularly.
Web 2.0 technologies allow people to converse,
communicate, collaborate and take collective action
as never before (Rosen and Nelson 2008, Shirky
2008). O‟Reilly (2005) conceptualized the Web 2.0
phenomenon as a reaction to the claims that with the
burst of the dot-com bubble, the Web was finished.
The term is used to describe how the World Wide
Web has changed to a collection of technologies that
have encouraged the evolution of communities and
services known as social software – Facebook,
MySpace, Bebo, LinkedIn; video sharing –
YouTube, Metacafe, Revver, Google Video, Yahoo
Video; wikis – Wikipedia; blogs – WordPress,
TypePad, LiveJournal, Blogger; and productivity
software – Zoho, Google Docs, ThinkFree Office,
Writeboard (Kroski 2008). MIT‟s iCampus project,
a recently concluded seven year, $25 million R&D
effort (funded by Microsoft Research) that focused
on building technologies that enable more effective
learning, is a good example of a Web 2.0 learning
infrastructure (Morrison and Long 2009). Users can
access the iCampus portal, observe its design, get
information about accessing material, and download
the open-source courseware. This project is entirely
open source, so you can implement material of your
own using their architecture. And visitors can try it
out; there is material that is publicly accessible.
Anybody can create an account by registering on the
welcome screen.
From a learning perspective, the advent of Web
2.0 has enabled students to use the Internet in a
completely new, participatory way. They can use it
to read about specific topics, but also to write and
contribute, as the barriers to content creation have
become so low. It is through this participation that
students are able to author their own online
experience, allowing them to have group
conversations as part of their learning experience.
Basically the only skill we assume our students have
is how to use a Web browser, and this has been met
without exception.
From a learning assessment perspective, the use
of Web 2.0 tools provides an opportunity for
instructors to observe the way students progress
along the stages of expertise (Dreyfus and Dreyfus
1986). There is a range of proficiency within student
groups. Working together, skills are transferred from
the more to the less skilled, facilitating a slow but
sure increase in proficiency and movement from
novice to advanced beginner and perhaps even along
the scale to competent user. By continually working
within the Web 2.0 learning infrastructure,
individuals will eventually reach the proficient and
expert levels, even though such achievement is
likely beyond the scope of our course.
From a problem solving and decision making
perspective, problem solving using computers has
been a predominant paradigm. Many courses are
dedicated to teaching skills in particular
applications‟ features and functions. Yet it is equally
important to know when to use a tool as it is to know
how when the time comes to solve specific
problems. The framework of problem solving and
decision making introduced along the use of
spreadsheets in a business context offers the
opportunity of presenting both the tool and the type
of problems in which they are used. Spreadsheets are
widely used in businesses. They are not only
powerful calculators, but also powerful tools for the
manipulation and analysis of data for decision
making. Spreadsheets allow discussions on what-if
analysis, financial analyses including rate of return,
amortization, and forecasting, and in converting data
into information. The goal is that students learn
„how to map a problem into a two dimensional
application using columns and rows.‟ They are
encouraged to explore new features and functions to
solve problems and support decisions. Along the
problem solving framework, the importance of
recognizing a problem is encouraged as well as the
analysis of available data to generate a problem
