Bosconians were amazed by science-related activities and exhibits in various categories. Director Sicat expressed strong support for research initiatives, highlighting partnerships with Tarlac State University and the Provincial Government. This experience cultivates a research culture and fuels innovation for the future!

From a wide array of students with special skills in Mathematics, four Bosconians were recognized by the Department of Science and Technology (DOST) Science Education Institute for their international contribution in their field conferring the Youth Excellence in Science (YES) Award, last January 30, 2024, at Fr. Balocco Gymnasium.

The YES Award is to recognize young men and women of science whose quest for excellence knows no bounds. The students who are awarded are; Julleana Marie Soriano, Jesse Alexander A. Mancao, Allan Matthew V. Verbo, and Royce Cendrick Y. Wong. These young mathematicians were accompanied by the Rector – Principal, Fr. Edwin L. Ulanday, SDB, Deputy Principal for Academic Affairs, Fr. Daniel R. Gonzales, SDB, and the Institution Research Officer, Mr. Karl Josh M. Guillermo. 

Don Bosco Tarlac Research Office initiated an inception meeting with the University of the Philippines Manila School of Health Science – Tarlac Campus to discuss the plans for future research collaboration and partnership, last February 12, 2024, UP SHS Extension Campus, San Isidro, Tarlac City. 

The inception meeting for research collaboration holds paramount significance for the educational research of the institution as it serves as the foundational step in developing research initiatives. 

The meeting was directed by the UP SHS Executives, headed by the acting director, Asst. Prof. Mary Cris Tablante-Rombaoa, and Don Bosco Tarlac’s Research Officer, Mr. Karl Josh M. Guillermo, together with the Institutional Affairs Office, headed by Dr. Therese Angela M. Caldez, External Affairs Officer, Mr. Ryan Benedict D. Gonzales, and CommDev Officer, Ms. Ivy Joy T. Gabriel.

The collaboration with UPM SHS Tarlac Campus can establish the framework and initial plans for the joint research endeavor shaping the trajectory and outcomes of the combined effort. The expertise of both institutions can be used in providing progressive research results that can be used for extension programs and adopted communities.

Being the first private school in the city to host the DOST-Regional Mobile Science Centrum (RMSC), Don Bosco Tarlac became this year’s home of DOST science exhibits.

The RMSC showcased 22 science-and-technology-based crafts and apparatus that enable students to establish scientific and innovative minds with principles, theories, facts, and concepts across science.

The said event is in partnership with the Department of Science and Technology-Tarlac (DOST-Tarlac), the Department of Education Tarlac City School Division (DepEd-TCSD), and Don Bosco Technical Institute Tarlac, Inc. Institutional Affairs Research Office.

In the welcoming remarks of Mr. Karl Josh Guillermo, Don Bosco Tarlac’s Institutional Research Officer, “The Mobile Science Center is not just a collection of exhibits; it is a gateway to a world of wonder and curiosity,” emphasizing that science has its own depth since there are many ideas to unlock and questions to explore as we delve to understand the concepts of each experiment in the science centrum.

DOST Regional Director, Dr. Julius Caesar V. Sicat, shared, “This event and place are an open invitation for our youth to explore the boundless concepts that science will bring us,” emphasizing the significance of this program to the youth in fostering science and innovation in our country.

Additionally, Dr. Irelyn P. Tamayo, DepEd Tarlac City Schools Division Superintendent, expressed that “If we want to make our nation not a third-world country, we must have a strong foundation in science, which will come, of course, from the brilliance of science teachers and DOST in this endeavor through interactive tools and equipment,” highlighting the aid and value of these innovative technologies in nurturing the knowledge of students, especially in science subjects, to be able to compete with students across the world. 

“Makaka-asa po kayo na ang City Goverment of Tarlac…, ay patuloy na naka-suporta sa makabuluhang programa ng DOST, na naglalayong palaguin ang Science and Technology bilang susi sa pag-unlad at progreso ng Tarlac City at ng buong bansa, lalo na ang pag-unlad ng pamumuhay ng ating kababayan…,” emphasized Hon. Kathrina Theresa Angeles in her inspirational message during the opening ceremony of the RMSC.

Don Bosco Tarlac invites teachers and students from various schools in Tarlac City to join, experience, and acquire new knowledge through having a moment with the interactive exhibits prepared by the DOST for Tarlaqueños.
