Introduction
In 1958, my father and I armed ourselves with paper and
pencil and sat down at the kitchen table to design the world’s first perpetual
motion machine.The truth is we didn’t
get much further than drawing some high-speed, low-friction gyroscopes, but we
had some interesting conversations.
It is now the year 2000, and just a few nights ago I
confronted a similar scenario when my own son asked about inventing an
anti-gravity machine for a science project. Knowing just how impossible an
endeavor this was, I quickly steered him away to some alternatives. Although we
did generate a few good ideas, it occurred to me that I might not have
developed an enduring interest in learning, science, and technology if my dad
had responded in the same way that I just did.
Fast-forward to 2006. My younger son comments that it
would be cool if we each had our own personal flying device to avoid automotive
gridlock and wonders if that might make a good topic for a school project. To
investigate his idea further we generate a few related questions and query
NetLearner to see what kind of information is available.
From NetLearner my son is surprised to discover that
Michelangelo thought about similar issues 500 years ago. After reviewing the
other available information and surveying the available research supports, he
narrows in on an interesting, but manageable topic: comparison of personal
flying devices between the years 1500 AD to 2006 AD.
Throughout this process, NetLearner proves an invaluable
resource. The NetLearner research tools provide the supports he needs to
explore the broad landscape of age-appropriate resources. More importantly,
NetLearner has been tailored to his unique interests and abilities: his reading
abilities and math skills, his tolerance for ambiguity, his need to survey the
larger picture before getting mired in the details, how he prefers to keep
track of information, and his tendency to over-analyze available resources. His
suite of tools is customized to exploit his strengths and scaffold his
weaknesses, while providing opportunities to extend his abilities in realistic
ways.
Considering some of the changes that new technologies will
make possible at school, at home, and in the community, it is important to ask
how these technologies will affect the learning of children with disabilities.

Technology and Learning
Many experts feel that technology has failed to
demonstrate any significant advantage over traditional non-technology based
approaches to learning.Yesterday’s
electronic learning and productivity software placed huge demands on teachers’
time and schools’ bank accounts. Furthermore, although technology-based
learning environments included a number of the essential learning elements,
each element required a lot of knowledge and introduced new opportunities for
error. Much could go wrong – and often did.
With a little planning, the hardware, operating systems,
software applications, digital content and networks may all be made fully and
readily accessible to a wide range of learners. Although this kind of
accessibility was still a significant problem just a few years ago, in 2006 all
students have complete access to new learning technologies. These technologies
can take us beyond a modest improvement in access to learning content and
activities to the stage of improving learning opportunities themselves.
In the year 2006, we
understand the importance of high expectations for all learners:
continuous assessment, the judicious use of technology-based supports and
scaffolds, the social context for learning along with new teaching and learning
strategies, and materials that are attentive to the principles of universal
design for learning. More importantly, we know that the technologies used for
learning have to be very easy to use – by everyone. The programs do the work of
customizing so that we can concentrate on teaching and learning.
This is not a high-tech, low-touch learning environment
and teachers remain a fundamental fixture in the learning process. The work of
Lev Vygotsky has been extended to social and electronic learning environments,
making it possible to know just how much support is appropriate and necessary
for each individual engaged in the learning process. In fact, technology
enables teachers to pay more personal attention to each student to ensure that
every learner functions within his or her "zone of proximal development". The
number of bored and frustrated learners has been significantly reduced and
school has become a place of high productivity and achievement for almost
everyone.

A Scenario for Education
In 2006, a Middle School is a wondrous place. Educators at
this level know that in the classroom working together offers huge advantages
for learners, educators, and the community at large, as we see in many
enlightened workplaces. Competition still exists in the classroom. However,
cooperative team efforts are generally more highly valued than individual
accomplishments.
The project is core to learning. Learners agree to work
together to solve difficult problems. Each student brings special talents and abilities
to the table, and various project roles are assumed so that everyone
experiences all aspects of the project at different times. Learners support
each other because that is what is required to complete a high quality product.
The products become part of a physical or electronic portfolio, and each
learner’s contribution is reviewed.
The cooperative trend involves teachers as well.
Increasingly, teachers are shifting from their place at the head of the class
to a position alongside their students, discovering, exploring, and solving
problems together.Most learning is
accomplished by a combination of teacher guidance, individual study, and peer
collaboration. Although this new learning environment brings with it new
challenges, teachers have quickly discovered the advantages over the more
rigid, pedantic, and isolated classrooms of the past.
Only a few years ago, statewide assessments compelled
teachers to focus on a well-defined set of skills and knowledge. Property values were at stake. Now, although
everyone still has a learning path outlined in advance, much of the excitement
is focused on "just-in-time" learning opportunities. When a skill is desired or
needed, teachers and students log on to the Internet and engage in lessons
designed by the best available educational designers.
This "just-in-time" learning is supported by mentors and
intelligent agents.Better yet, the
technology-based learning program knows both the type and amount of support
appropriate for each learner. For example, it knows when and how best to
provide outcome models, request learner summaries to support reading
comprehension, check for recall of essential facts, and offer help with
analysis and organization.
Technology facilitates every stage of the learning
process. In the early stages, teachers can readily find the tools necessary to
gather, analyze, and organize information. When the students are ready to
demonstrate what they have learned, they can easily select from multiple
options for expression. With these technological tools assessment is
transformed from a terminal process to a continuous one where a student’s every
action can be used to analyze progress. New software tools help determine what
aspects of performance are most important to keep track of and how best to
present these central concerns to learner and teacher. This would be a hugely
difficult task if not for technology, which provides the learning team with
easy-to-use data summaries that they can use to make important decisions about
future directions.
A few educational publishers still produce textbooks, but
most schools have found that it is more productive and cost effective to
license specific content, as it is needed to accomplish particular project
goals. Publishers have worked hard over the past few years to provide digital
content and activities to the growing number of digital libraries used as
resources by learners around the world. Most publishers have found it
productive to tag their content and activities with meta-data that facilitates
its selection and use for various activities. Tagging standards now make it
possible for schools to quickly locate content from both large and custom
publishers and use it within the context of a lesson or project.
A few schools are now experimenting with electronic
locator and selector tools that build smart digital agents that help locate
content, activities, and learning tools aligned with established local
criteria. These new services hold great promise for saving time and money and
preventing problems associated with the purchase or license of materials that
are not properly aligned to established standards and local preferences.
Thus, although schools and publishers were concerned about
giving up the security and predictability of the textbook and supplementary
learning materials, most have now adopted the new method for selecting,
licensing and using such materials
Continuous learning experiences are now available not just
in the classroom but also in the library and at home. Homework is no longer
simply an opportunity to independently study, practice, or perform. In fact, it
is difficult to distinguish many aspects of regular classroom learning from
learning outside the classroom.Project
teams continue their work at home, sharing new ideas, resources, and content.
Learning and assessment are continuous.
Fiber optic and broadband connections are now pervasive in
most homes, and devices such as inexpensive, hand-held computers are widely
used. Teachers and learners can simply identify the device in use, and the
Extensible Markup Language and Extensible Style Language (XML and XSL) based
learning materials can be "downloaded" to fit that device’s requirements. Only
a single source of the content or activity is required, and it can easily be
provided for desktop, laptop, or portable handheld PCs. A few students even do
parts of their assignments on their cellular phones.
None of this was very practical just a few years ago when most of
the content was "hard wired" in HTML.
Furthermore, in today’s world technical requirements for
schools, families, and individual learners are minimal. Very few activities
require software to be installed on a particular client device. Instead, most
software resides on an active server and is easily updated by the provider. In
short, technology is now provided as a turnkey service, enabling educators and
learners to concentrate on education and learning.
The now near universal access to the content within the
technology also frees up educators to focus on improved learning. Assistive
technologies such as screen enlargers, switches for scanning, voice
recognition, and special type-ahead and word prediction programs are seldom
required, because all approved software programs now have built-in supports for
sensory, physical, cognitive and affective difficulties.
Teachers also have access to a rich variety of
cross-discipline content. Although many teachers are still required to have
content area specialties, teaching and learning is generally accomplished in a
way that blurs the lines between specific disciplines. In this environment,
cognitive development, problem solving, and socially appropriate work skills
are critical. Teachers and students work together to practice these skills and
monitor progress in these areas on a regular basis. No one is exempt.
In a cooperative planning session, teacher and student
develop flexible learning paths. Together they devise a set of well designed
and mutually agreed upon goals, suited to the individual learner’s skills. They
also decide on the appropriate scaffolds for doing research, analyzing and
organizing content, and demonstrating knowledge.
Basic reading, writing, math, and thinking skills are no
longer taught apart from compelling project-based subject matter.
Beyond the third grade, skill development is
embedded within the project work. Curriculum experts can continuously examine
what is worth knowing, because facts are easily obtained, organized, and
applied to new learning situations. Exemplars can be generalized, and learners
are proficient at using reference materials and pattern recognition and
generation tools.
Teachers and learners fully understand the difference
between access and learning, and when high degrees of access and support
diminish opportunities for learning, resistance is introduced.
Just as resistance can build muscle in the
weight room, it can provide appropriate learning challenges in the
classroom.If the automatic "main topic
highlighter" stands in the way of the learner becoming independent and
strategic, its supports are diminished.

A Scenario for Accessibility
Access to content and learning is simply a first step. In
2006, it is no longer considered an educational solution but rather a basic
right. All learners now have access to information and learning experiences in
the necessary and preferred modalities.
Following guidelines developed by the National Center on
Accessing the General Curriculum in conjunction with other organizations like
the World Wide Web Consortia Web Accessibility Initiative (W3C-WAI), and NISO,
publishers provide content that is accessible from the start. Images, links,
charts, and tables have long descriptions; digital movies include captions and
video descriptions, and auditory media incorporate text and other visual
representations.Electronic books are
published in a format that make them usable in many environments and by
individuals who require unique supports while reading.
Top
Electronic Books
Publishers routinely include features that make text both
accessible and more intentionally supportive of learning since text is now
widely available in digital format. Synthetic speech along with synchronized
highlighting of the spoken text is readily available. Direct links to reference
materials are simple to use, and definitions are provided with consideration
for the context in which the term or phrase was originally used. Content is
presented with usability in mind. Presentation is clear and straightforward,
and selected tools, supports, and scaffolds easily integrate within the
learning environment. Simple navigation controls allow learners to quickly find
what they need.
New standards and technologies make access even more
automatic by making it possible to create content just once and then provide
opportunities for multiple expression suited to the needs and desires of each
individual learner. For example, the same XML content source can be displayed
in a browser, printed, used as a source for refreshable Braille devices, or
spoken with high quality expressive synthetic speech. It can be displayed and
voiced on desktop computers, notebook computers, handheld PC’s, personal
digital assistants, and digital portable telephones.

Goals for Learning
High standards for all learners remain a critical
component of our nation’s year 2006 effort to improve educational opportunities
for learners with diverse backgrounds, styles, and abilities. Access to,
participation in, and progress within the general curriculum remains the
cornerstone of school reform efforts for diverse learners. Fewer than two percent
of students require significant alternatives to the general education
curriculum and the built-in educational assessments.
Inability to graduate from high school due to poor
performance on high stakes assessments was once a significant barrier to
entering higher education programs and acquiring productive employment. Over
the past few years, many public schools have retained students with identified
special needs until they demonstrate proficiency in reading, mathematics, and
writing as well as basic knowledge of science, history, and government. The
increased costs associated with providing educational programs beyond the 12th
grade have provided schools the incentive necessary to implement improved
programs of early identification and support within the general education
program.
What has changed are not the standards, but the options
for reaching those standards. We can now more carefully individualize the goals
that we derive from standards, as well as the paths that lead to those goals –
through more flexible methods and materials. With those options has come a
closer scrutiny of the learning needs of students, and the educational
alternatives with the curriculum. Identifying the proper balance of support and
challenge demanded by a particular learner within a selected context is now
critical to the provision of a properly "tuned" educational experience. When
the goal is to improve knowledge of some historical event, for example, it is
now commonplace that we allow learners to use a variety of needed supports and
scaffolds – such as text-to-speech reading – for accomplishing that specific
goal. However, when a struggling reader is easily able to grasp the concepts
within a history lesson, it may make sense to reduce the reading supports and
give the student an opportunity to practice reading and comprehending
completely without supports. In this case, the goal is both greater
independence in reading and improved performance in history.
This is a topic rich with opportunities for future study.
We do not yet know whether students who read a great deal of their
subject-matter content in a supported reading environment (e.g. with
text-to-speech capabilities) will learn to read more quickly or more slowly
than students in unsupported print environments. We might also ask what is the
proper balance of the familiar and novel for a particular learner within a
particular learning activity. The learning technologies available in 2006
enable us to experiment with these settings, but much more data collection and
analysis must be completed before individualization can be accomplished
automatically, without human intervention.
One result of this flexibility is a decreased insistence
on the same performance goals for every student within a given standard.
Instead, we recognize the value and opportunity that lies in diversity. We
spend less time trying to make all of the students perform at the same level in
one limited area of expertise, and more time trying to identify every student’s
strengths across a wider range of capabilities. As a result, we provide more
balance for developing and demonstrating proficiency in all receptive and
expressive modalities. We now know how to provide opportunities for basic
development skills such as reading and listening, writing, speaking, drawing,
sculpting, and computing, as well as higher order ones such as research and
analysis. We know how to provide a balance of individual and group learning
opportunities that encourage the development of self-esteem, sociability,
self-management and integrity. Smartly embedding what is already known within
classroom and electronic learning environments will continue to challenge
curriculum developers and publishers for many years.

Universal Design for Learning
The Universal Design movement in architecture was
motivated by the realization that designing buildings with built-in
accessibility to everyone was a far superior approach to making posthoc
modifications. On the heels of the Universal Design movement in architecture
came a similar movement in education. For those designing educational
environments, building an accessible building from the start provided many
financial and practical advantages. For those designing educational
instruction, parallel advantages became clear at the beginning of the third
millennium. Educators and curriculum designers realized that teaching
approaches and curriculum materials that were designed to be flexible and
supportive of diverse learning needs would have a clear advantage in the
marketplace.
CAST developed the idea of Universal Design for Learning
(UDL) as an educational application of the concept of Universal Design. The
basic premise behind UDL is that curricular content should be provided in
multiple representations or in a transformable format such that multiple means
for expression, control and engagement are built into each learning activity,
enabling every student to learn from that curriculum. Thus, UDL promotes new
standards requiring teaching curricula flexible enough to accommodate the
entire spectrum of learners.
Together with educators, CAST realized that the
educational materials best able to meet these new requirements are digital
materials. Electronic learning environments readily overcome physical
disabilities that could prevent access.
Supports such as keyboard shortcuts and access keys provide access to
those whose physical challenges prevent them from using a mouse. Simple
switches may also be used to navigate the electronic environment.
However, UDL goes beyond mere access. With digital content
it is easier and more cost-effective to provide multiple representations of the
same content (e.g. image and sound), to transform one media to another (e.g.
text-to-speech), to alter the characteristics of a presentation (e.g. size,
color, contrast), and to provide the same basic content at varying levels of
difficulty. Furthermore, digital content is usable by a wide variety of display
and presentation devices (e.g. computer, handheld, phone), enabling students to
express themselves using writing, speech, or drawing within the same electronic
environment.
Publishers have responded to UDL in an extremely positive
fashion. UDL has helped them to produce content that can be customized to
regional and individual needs and will eventually provide a mechanism for the
elimination of multiple versions of the same content.
UDL also considers learner engagement essential. Digital
technology offers the means to tailor learning to personal interests and
abilities. Students who need to feel that they are in charge of their own
learning now have the tools for working with educators to establish appropriate
learning activities.
Thus, in a universally designed classroom, the goals for
learning are flexible, assessment is continuous, and students are provided with
the tools necessary to adapt media and materials to their individual needs.
This may have seemed impractical just a few years ago when most curriculum
materials were provided on paper, and instruction was primarily provided by
frontal teaching methods. However, in 2006 the electronic learning environment
– supported by searchable and flexible digital libraries, knowledgeable
teachers and learning specialists, and an appreciation for the value of
diversity within schools – has significantly altered our conception of what is
possible.
Top
Support and Challenge
We now know that students with disabilities – in fact all
learners – fall along a continuum of learner differences. Although standards
should remain high for all students, it is realistic to assume that they must be
adjusted for a few. The goals for a particular learning activity will differ
depending on how information is presented and how strategic the learner is
within the context of the activity. The goals set must also take into account
various affective issues such as the need to be in control, the amount and type
of feedback needed, persistence, and tolerance for frustration.
Recent studies have taught us that productive learning
richly engages the brain. However, if a task becomes too challenging, learning
is less efficient. Educators
know that low expectations are detrimental to learners of all abilities, but
determining the proper amount of novelty and the appropriate balance of support
and challenge can be vexing, even to the experienced teacher.
In 2006, most decisions about support, challenge, and
novelty are determined cooperatively, by teacher and student. These decisions
are made based on data from past performance, which can be maintained on a
central server.Thanks to newly
available tools, this data can be visualized and analyzed rapidly and
efficiently by teachers trained to support all types of learning. It is worth
noting that the flexibility available within these data analysis tools provides
an important exemplar for educators who quickly realize that they, too, need to
be strategic in ways that may differ significantly from their peers.
Analysis software is now being modified to provide a
customizable mix of teacher, student, and technology adjustments to the
learning content, activities, and tools. Although it soon may be possible for
the software to do much of the work, many teachers are finding that the process
of evaluating progress and determining the appropriate future path is an
extremely valuable exercise and are therefore likely to use the computer
generated data simply to monitor their own decision making. In fact, so much is
being learned about maximizing learner opportunity via continuous assessment
that the more formal terminal assessment tools have not been able to keep up.
Those who wish to recapture testing time in
order to maximize learning opportunity view this turn of events in a very
positive light.
Top
Cognitive Scaffolding for Individuals and Groups
Awareness of connections to personal experience, the past,
other fields of study, and even the future help to make us smarter in our
day-to-day endeavors. Only recently have researchers and developers begun to
seriously address how making these kinds of connections can help us to learn
and create in the classroom. They have found that technology can help us to
discover links that are not obvious to casual observers. In years past, learners worked long and hard
to discover relationships. Now, a growing population of learners can do it
quickly with the benefit of scaffolds and supports that display keyword
connections, provide "compare and contrast" summaries, generate concept maps
that expose main ideas and supporting details, show relationships between
current and past events, and step learners through an active inquiry process
designed to expose relationships. Some feel that these new tools can be likened
to the sensory and physical assistive technologies of the past, but others view
them as much more, as tools that extend one’s capabilities.
The key is that these cognitive supports are increasingly
available within all curricular materials, a normal and expected part of
educational design. In addition, new reading and display devices can now keep
track of essential points using colors and sounds designated by the learner for
specific purposes. For example, items which are likely to be useful for a
particular project can be highlighted in green if they are deemed "sort of
interesting and worth revisiting". At the appropriate time the marked text and
media, together with annotations and bibliographic information, can be easily
collected for the development of a project or presentation.
So far, we have focused on individual supports. However,
group supports for working collaboratively are also now common in 2006.
Students often contribute to a common document stored on a remote server. The
document is developed over time by a team that agrees in advance how different
individuals would best contribute to its evolution. Content is marked to
indicate authorship, and annotation by anyone in the group is possible at any
time. Of great value to the working group is the ability to build a common
favorites file on the server so that everyone benefits from the Web-based
resources located by each member. Members can even use a rating scale to rank order
the resources by perceived value.
Top
Fostering Growth and Independence
Learning takes place just about everywhere and at any time
in 2006. It was difficult to accomplish, but deliberate planning has finally
made academic achievement for all a desirable outcome. All of this was
accomplished within the context of a social learning environment that
encouraged and rewarded group work and project based learning and placed a high
value on problem solving and continuous improvement of basic skills. Team
achievements in the classroom now receive higher recognition than success on
the football field.
In this new educational environment, each individual’s
contribution is critical. No one is left behind or allowed to slide by because
of the efforts of others in the group. Students are taught to provide feedback
to other learners and to self-monitor their performance. Technology is used to
record progress. Teachers, parents, and students often meet to review the data
in an environment where self-monitoring is highly valued and asking for help is
considered beneficial to all.
The systematic withdrawal of supports and scaffolds within
and across the various projects is considered necessary to foster growth and
independence. Over time, novelty and challenge within the project activities
are introduced more frequently to provide opportunities for developing new
strategies for independence. For example, the server software makes fewer links
and connections, and students are periodically challenged to work on a more
individual basis. Depending on feedback and conference discussions, some
supports and scaffolds may be withdrawn altogether for brief periods to ensure
easy access to a wide range of educational supports is not creating unnecessary
dependence.

A New Role for Special Education Services
Now that accessibility is built in, teachers spend very
little time inventing new accommodations and modifications for basic access to
content and learning experiences. Their focus is not on "disability" and
identifying problems in children. Instead their focus is on learning, and
identifying barriers or opportunities in learning materials. A learning
specialist in 2006 knows a lot about learning and knows how to plan and adjust
support within the content of the general curriculum so that every child is
maximally in their zone of proximal development. She knows how to evaluate
performance data and how to collaborate with teachers, parents, and students to
provide recommendations for the right balance of social interaction, on-line
customized content, skill advancement, performance, and teacher consultation.
The disability and special talents training she has participated in provides
her with general guidance for making adjustments to the learning environment.
Diagnostic testing was banned in 2005, because it provided
limited, decontextualized "point-in-time" data and was used mostly by
clinicians to label and categorize children in ways now thought to be
unproductive.Categorical labels are
now of limited value. Individual Educational Plans are prepared for all
students, but these plans are based on day-to-day performance and periodic
conferences with learning specialists, educator teams, and parents. A
continuously updated record of activities, preference settings, computer
mediated adjustments and performance provide the summary recommendations, and
predictions that are needed by the learning specialist to optimize learning
with consideration for social and emotional development.
The learning specialist is considered an integral part of
each education team and provides support for other team members, parents, and
students. They are available to address the unique learning needs of all
students and are trained to facilitate a decision making process that results
in improved learner performance. In 2006, fewer than ten percent of all
learners require special amendments relating to their specific significant
sensory, physical, cognitive, emotional, social, and health issues.

Summary
In the year 2000, teachers indicated that they found it
difficult, if not impossible, to modify teaching methods and curriculum
materials to meet individual student needs. Some thought that this condition
was due to years of special services provided by special educators who were all
too willing and able to assume responsibility for students identified as having
special needs.
In 2006, we do not think about special education as a
separate program or service. Instead, all learners benefit from the work of the
school’s learning specialists. Access to the general curriculum, as well as
participation in and progress within the general curriculum, is considered a
right. We now have the social learning environment, trained educators,
instructional methods, flexible content, and technology tools necessary to
guarantee this right for everyone.
As my son searches the Internet and his personalized
learning environment using NetLearner, he quickly collects, organizes, and
analyzes information he will need to discuss his personal flying device project
in school the next day. In other
homes, students approach the same task but perhaps in very different ways. In
the year 2000, some of these supports would have been impossible, and some of
these students would have been considered "disabled".
Instead, they have grown up with tools that are as varied and as
flexible as they are. Tomorrow, in school, they will form a diverse team to
collaborate on this project, and they might just make something very special.

Additional Resources on the Web
The Technologies for Achieving the Vision
The technologies that will be needed in 2006 are mostly
available today. However, they have not
been fully developed, nor have the development and monitoring tools required by
publishers and educators been standardized.
Extensible Markup Language (XML), Extensible Style
Language (XSL), and secure personalization and digital rights technologies will
soon provide benefits to learners that eluded educational developers for years.
Format, structure, and content selection by XSL can render appropriate content
on browser screens or for printing and even generate refreshable Braille. Since
there is now some agreement on which meta-data are appropriate for education,
course developers and on-line content delivery warehouses can provide
educational programs customized for selected standards, needs and interests.
Standalone XML pages will give way to those controlled by a Document Type
Definition (DTD) file customized for a given purpose or field of study.
The tools for creating custom tags for XML
are just emerging and within a few years, it may be practical for educators to
create their own.
XML Pointer Language (XPointer) and XML Linking Language
(XLink) can provide essential resource connections over the Internet. In
addition to simple links, XML can provide links between multiple resources and
links between read-only resources. XPointer describes how to address a
resource, and XLink describes how to associate two or more resources. As these
technologies mature, customized content and personalized learning activities
will become pervasive within our schools.
The IMS Global Learning Consortium, Inc. delivered open
specifications for the technical building blocks of online learning in June
2000. The IMS Content Packaging Specification and the IMS Question and Test
Interoperability Specification, as well as Version 1.1 of the IMS Learning
Resources Meta-data Specification, were approved and released. The
specifications are designed to provide standards, such as meta-data, for
educational purposes and will be used to provide the greatest possible
integration of various competing on-line learning environments. The IMS Content
Packaging specification will allow us to define course content and then deliver
it using a standard XML-based descriptor.
Tools for acting on content will also mature. Talking
browsers will provide a visual representation of content while offering
text-to-speech or SMIL controlled MP3 digital voice files to read while
highlighting the content. SMIL is the Synchronized Multimedia Integration
Language that will be used extensively with Scaled Vector Graphics (SVG) to
offer high quality customizable multimedia presentations. Cognitive support
tools will become easier to use and will be integrated with our content
presentation browsers.
Interwoven support and scaffolding capabilities will be
built into the server side applications, the client-based tools, and the
educational content.Wireless Internet
access for all media types and handheld personal computers will become
pervasive for communication and learning. The goal is to provide every learner
with the ability to log onto his or her learning environment from any available
device from any location. In 2000, this is not practical. In 2006, it is a necessity.
