Khan Academy has been an invaluable resource for learners of all ages. Their extensive library of instructional videos covering a wide range of academic subjects, from mathematics and science to history and the arts, has empowered millions of students to learn at their own pace and master key concepts. The organization's commitment to providing free, high-quality education to anyone, anywhere, is truly admirable. Khan Academy's innovative approach, which includes features like progress tracking and interactive exercises, has revolutionized the way we think about learning and teaching. We are grateful for the hard work and dedication of the Khan Academy team, whose efforts have made a profound impact on education around the world.

Also, we would like to extend our sincerest gratitude to Dr. Darrel M. Ocampo, who served as the panel chair for our research project, "Flipping the Mathematical Classroom: Effectiveness of Khan Academy Videos in Teaching Calculus 1 to Math Majors." We are also deeply thankful to Prof. Salvacion A. Eje, Prof. Julie B. Llagas, Ms. Donna Claire Caneza, Ms. Mary Grace Aureus, and Mr. Teodoro Jan Mirate, who comprised the panel and provided valuable insights and feedback throughout our research. Their guidance and support allowed us to successfully conduct our study, which aimed to investigate the effectiveness of Khan Academy videos in teaching Calculus 1 to math majors through a flipped classroom approach. We appreciate their dedication to fostering academic excellence and their commitment to ensuring the quality of research in our institution.
