4. Why?
1. Insufficient science equipment; Teachers resort to oral
instructions in lieu of manipulative materials.
2. Lack of science rooms (even in science high schools).
3. (Some) Principals lack the basic training in science.
4. Science instruction is done incidentally; concepts
incorporated in English.
5. (Some) Teachers lack the basic science information and
training.
6. (Some) Teacher training schools do not give emphasis in
science as a subject.

5. Proposed Solution
• Start a program to develop low-cost
multipurpose instrumentation and laboratory
modules for Philippine secondary schools.
• Hardware is a handheld, microcontroller
controlled unit, working with a wide
assortment of plug&play sensors and probes.
• Open source system to allow 3rd party
developers to contribute “apps”.
6. Program Implementation
• Development is over 2 years
• Begin with 2-week summer workshop to
introduce the idea to the smartest and brightest
recruits and students of the UP system.
• They will be trained and will develop prototype
laboratory modules.
• Activities will followed by an intensive
development, testing, validation, manufacturing,
documentation and deployment phases.
7. Benefit to Higher Education
• Participants will gain extensive knowledge of
microcontroller
systems, electronics, mathematics, oral and
written communications;
• Exposure to design processes under realistic
constraints including economics, political and
ethical dimensions;
• Instill spirit of working for the common good.

14. The Opportunity: Enhancing
Education and Tapping into
Filipino’s Ingenuity
• Excellent opportunity exists in the Philippines to design
and develop home grown content-driven system to
alleviate lack of labs in secondary schools and modernizing
them.
• We will tap the Filipino’s creativeness and resourcefulness
to develop low cost but sophisticated instrumentation to
benefit the Filipino people.
