In this new normal, children are immersed more in using gadgets like cellphones, laptops, and notepads, and even watching different programs on television which has been shown to have both positive and negative effects on the child’s vocabulary acquisition, pronunciation, and comprehension. They are growing up highly immersed in digital media and engaged more in watching online videos using different applications. Mostly, parents allowed their children to use their gadgets without limitations anytime and anywhere. The general goal of the study was to find out the influence of online educational videos on the child’s vocabulary acquisition, pronunciation, and comprehension using Piaget’s Accommodation Theory. It also seeks information if Piaget’s Accommodation theory is relevant and effective in the present situation where children are engaged more in using gadgets rather than browsing books. The subject of the study was a four- year old child observed for four months watching online educational videos on YouTube five times a week regularly. Printed assessment, observation, video recording, and an interview were done to determine the progress of the subject in acquiring new vocabulary. The findings of the study revealed that watching online educational videos on YouTube has a positive effect. It influences the child in acquiring vocabulary, pronunciation, and comprehension. It also helps to develop the intellectual, social, emotional, and spiritual aspects of the child. A child who watched online educational videos on YouTube gains new knowledge, filtered it, and made interpretations based on reality. Based on new knowledge, old ideas are revised or even abandoned. A child’s vocabulary development benefits from watching educational videos online, but only under the supervision of parents or other adults. It also proves that Piaget’s assimilation and accommodation theory is relevant in the present situation even though high technology is widely used.
