Mark Joseph L. Mendoza is a Mathematics teacher under the Senior High School Department of De La Salle Santiago Zobel School - Vermosa Campus. He is a Microsoft Certified Educator, Microsoft Education Ambassador, Microsoft Innovative Educator Expert, and Google Certified Educator Level 2. He has been chosen as one of the attendees of the International STEM Studio Seminar which was held last July 2018 in California. Likewise, he was also selected as a speaker in a number of technology-related seminars such as STEP (Society for Technology in Education Philippines), Apple Education Leadership Summit, and EduTECH Philippines. Mark believes that teachers should always prioritize pedagogy more than the use of technology in the classroom, but having a combination and balance of both is better. Further, he also believes that teachers are the instructional material.
