Final answer:
Colonial mentality is the Filipino trait that works against the shift in the teacher's role from the teacher as a fountain of information to the teacher as a facilitator.
Step-by-step explanation:
The trait that works against the shift in the teacher's role from the teacher as a fountain of information to the teacher as a facilitator in the Filipino context is Colonial mentality. Colonial mentality refers to the mindset of valuing and adhering to Western ideals and standards, often at the expense of local culture and traditions. This mindset can make it difficult for teachers to embrace the idea of facilitating student learning and encouraging critical thinking, as it may conflict with the traditional hierarchical role of the teacher as the sole provider of knowledge.
