Abstract: Sharing knowledge not just led to improved learning on the part of the receiver, rather, the knowledge giver could also benefit from it. This descriptive phenomenological study delved into knowledge sharing motivation of students under the Curricular Program for Science, Technology, and Engineering at Laoang National High School. Ten purposively sampled informants participated in focus group discussion with three follow-up semi-structured interview the data from which were analysed through Colaizzi (1978) method. Results indicated that communal relationship, selflessness, and no-one-gets-left-behind mantra emerged as the most predominant themes which also reflected certain noteworthy Filipino values. This direction could point to researches which unravel novel knowledge sharing activities that further polished the critical thinking skills of students.
