RATIONALE
Technology, especially computers and computer-related peripherals, have
grown tremendously and have permitted all areas of human lives. It has undoubtedly
permitted the world of education. Hence, educators must prepare for a technology-rich
future and keep up with change by adopting effective strategies that infuse lessons with
appropriate technologies. Indeed, technology makes education become more exciting
and interesting to students.
One of the most important and commonly used materials in teaching is the
chalkboard and whiteboard. It is used in writing information discussed by the teacher or
by the students in school. It allows a better interaction between the teacher and the
students. Nowadays because of technological innovations, teaching techniques are
improving. Presenting lessons or reports by means of projector are widely applied. It
gives a visual presentation of what is being discussed, but using the projector takes much
time and more effort especially in operating the PC or laptop by its conventional mouse.
Most classrooms use ordinary blackboards and whiteboards as their
visualization tool. During class, writing the topics to be discussed in the board takes
much of the teacher’s effort and time. Teachers and students are used to it but they still
need convenience in learning. Also, in electronic presentation like PowerPoint, Word or
Pdf files, the teacher takes time in manipulating the computer while discussing.
With these reasons, the presenter decided to develop ALIW Management
based on Johnny Lee’s concept. It allows instructors and students to manipulate the
whiteboard electronically. It is a low-cost alternative interactive whiteboard that uses IR
camera in a Wii remote and IR LED as a pointer.
LITERATURE BACKGROUND
Education is the formal process by which society deliberately transmits its
accumulated knowledge, skills, customs and values from one generation to another.
A right to quality education has been created and recognized by some
jurisdictions: Article XIV, Section 1 of the 1987 Philippine Constitution states that:
The State shall protect and promote the right
of all citizens to quality education at all
levels, and shall take appropriate steps
to make such education accessible to all.
A quality education leads to an excellent student education.. There are ways
to ensure that a quality education always equals an exceptional student education. The
future of the country depends on a quality education being provided in every school. It
plays a major role in the student education. Using a framework that increases quality
education in school districts can help design maps to continuous improvement in student
education.
The fundamental purpose of education is to gain knowledge, inculcate the
forms of proper conduct and acquire technical competency. Education serves as the
means to develop oneself physically, mentally and socially. The importance of education
to youths manifests itself in terms of the need to cultivate the youths of society into
mature individuals.
Recent surveys show that student education is no longer based around the
basics. In order to obtain a quality education, the fundamentals must be taught. Student
education relies on the basic skills in order to succeed. A quality education begins with
the fundamentals like, problem-solving, teamwork, and organization. These core
principles create a quality education and promote an exceptional student education.
It is also important to create a way to measure the progress of students. There
will always be topics and subjects that are harder to teach than others. It is important to
assess one’s methods and students’ progress often to make sure no child is left behind.
Meaning no child is left not understanding what was taught (Phil-race articles - 2008).
According to Barbara Gross Davis's book, "Tools for Teaching", students
need time to assimilate new information and to take notes, but if the teacher speaks too
slowly, they may become bored (Brown, 2011).
Chalkboard is seen as just another thing but it plays a vital role while
cherishing the memories of school and classrooms. Chalkboards are the strongest
medium to impart education as it helps to explain the topics with diagrams. The amazing
thing about chalkboards is its history. It enables teachers to present written information
to a room full of students at once, a task that was nearly impossible before the early
1800s.
In recent years, interest in the use of technology in education has come into
prominence as a national goal. Currently, more than ninety five percent (95%) of public
schools have computers (National Center for Education Statistics, 2000).However,
knowledge about how to best apply this technology to educate and train has been an
unresolved issue for researchers for more than 50years (Perez, 2003).
To initiate this need, invention of Interactive Whiteboard came. A commercial
interactive whiteboard is a piece of hardware that looks much like a standard whiteboard
but it connects to a computer and a projector in the classroom to make a very powerful
tool. When connected, the interactive whiteboard becomes a giant, touch-sensitive
version of the computer screen. Instead of using the mouse, you can control your
computer through the interactive whiteboard screen just by touching it with a special pen
or, on some types of boards, with finger. Anything that can be accessed from your
computer can be accessed and displayed on the interactive whiteboard, for example
Word documents, PowerPoint presentations, photographs, websites or online materials
(IWB solutions - 2008).
Although this invention is a very useful thing, it can’t help those schools and
establishments whose funds are not capable of purchasing this tool. An interactive
Whiteboard may cost USD600-USD3000 depending on its specifications. In this case,
this is only available to those rich schools that have lots of extra funds to purchase it.
This is the main reason that the presenter was able to come up with the
solution of providing a low- cost alternative interactive whiteboard to be used in
classrooms of Bohol Island State University Main Campus.
Interactive projection systems typically require a dedicated location tracking
technology for the purposes of cursor or controller input. Many research systems
exploring projector-based augmented reality of the projected imagery onto physical
surface which is done either manually, using camera other tracking device. Using IR
patterns, it can discover the locations of light sensors in a manner that is invisible to
human observer while visible patterns provide application content. By unifying the
location tracking and projection technology into a single device, it will greatly simplify
the implementation and execution of the interactive projection systems and inherently
support multi-user stylus input on surfaces (Lee, 2007).
DEFINITION OF TERMS
Chalkboard. A reusable writing surface on which text or drawings are made with
sticks of calcium sulfate or calcium carbonate, known as chalk.
Computer. An electronic and programmable machine that receives input, stores and
manipulates data, and provides output at high speed according to program instruction.
Interactive whiteboard. An interactive whiteboard is a large, interactive panel that
connects to a digital projector and a computer, displaying the information on the
computer screen and can be controlled by touching the board directly or by using a
special pen.
IR (Infrared). Is electromagnetic radiation with a wavelength longer than that of
visible light.
IR camera. A device that forms an image using infrared radiation, similar to a
common camera that forms an image using visible light.
Mouse Pointer. Shaped like an arrow or a small hand with the index finger pointing
towards the top of the display device. The mouse pointer moves as the user moves his
or her mouse and is used as a reference point to where the mouse is located on the
display screen
Quality Education. The education which fulfill the desired knowledge standards and
skill suitable for the time being.
Technology. The usage and knowledge of tools, techniques, and crafts, or is systems or
methods of organization, or is a material product of these things.
Whiteboard. A non-electronic variation of the traditional "rewriteable" classroom
blackboard, but is white instead of black and of a material that can be written on with
colored markers (known as dry erase markers).
WII remote. Also known as Wiimote, the primary controller for Nintendo's Wii
console.
OPERATION
To start operating the Alternative Interactive whiteboard, add first the
wiimote controller to the computer’s Bluetooth device list. Pressing buttons 1 and 2
simultaneously or CALIBRATE button will make the wiimote into discovery mode
allowing the computer to connect. Wait until the status bar becomes green. It indicates
that it’s ready to use.
When manipulating the IR pen, be sure not to block the IR camera because it
will loss contact with the IR light. In order to have better tracking, ensure that the
wiimote is placed not too close but not too far with the surface with a field of view to
about 45 degrees. One can shift the mouse command from its default left click to right
click by pressing the “toggle right click” button allowing more convenience during the
process of manipulating the Interactive whiteboard.
When charging the IR pen, the LED indicator will turn off if the battery is fully
charged. It can be charged to any USB port or any 5v DC power supply.
