Enhancing Education and Tapping
into Filipinos IngenuityUnique opportunity in the Philippines to design anddevelop home grown content-driven system to
modernize labs in secondary schools and leaf frog
other developing nations. Tap the Filipinos creativeness and resourcefulnessto benefit KAPWAFilipino.We should not miss the opportunity.
