It must be noted that Lope K. Santos addressed the First Indepence Congress on 30 February 1930 by expounding on "The Vernacular as a Factor in National Solidarity and Independence." In 1932, Representative Manuel V. Gallego authored Bill No. 588 which provided for the use of the vernacular as the medium of instruction in all public elementary and secondary schools.
Itinaguyod ito ni Representante Manuel V. Gallego sa kanyang pagpasa sa Panukalang Batas Bilang 588 na nagtakda sa wikang bernakular bilang wikang panturo sa elementarya at sekondarya sa lahat ng paaralang pampubliko.
