Math

The Trinity Mathematics Department realizes all students progress through levels of cognition and maturity. The Trinity Mathematics Department accurately assesses entering students and provide developmentally appropriate mathematics courses at every level. The teacher’s role is to identify a student’s individual strengths and weaknesses and to provide a challenging environment that promotes growth and development, meeting students at their level of competency. Students are regularly assessed to ensure progress and readiness for subsequent coursework at Trinity School or in college. The Math Department works toward the following “big picture” goals for every student:
  • As a college preparatory community, we want our students to graduate with the skills and confidence to be successful at any university in any discipline.
  • Students need to finish each course with a strong foundation in both knowledge and skills that prepares them for the following course.

Faculty spotlight: Mr. Phil Edwards

Phil Edwards, Math Dept. Chair
Phil’s high school experience in math and physics sparked a passion for the sciences, so he entered college planning to major in engineering. During college he felt a “call” to some form of ministry and fell in love with teaching and learning. He attended Southern Baptist Theological Seminary, then, believing he was meant to teach, he visited with school districts in San Antonio and found a need for math teachers. After emergency certification,  he worked with students at all levels and definitely feels it has been the affirmation of his calling. He also completed the additional hours in math at Southwest Texas University and Texas Tech.

Phil has taught in public schools for 36 years – in San Antonio, Midland, and as an adjunct instructor at Midland College for 23 years. He is married to Paula Edwards who taught choir at Lee High School for 26 years. They have twin daughters: Elizabeth (a junior high choir teacher) and Clare (a senior recruiter for Vail Resorts) and two and a “half” grandchildren: William, Elia, and one due soon.

As a teacher, what he finds most impressive about the educational experience at Trinity School is the collective commitment to education. With the stated mission to be a “ college preparatory community,” the administration, faculty, and students actively strive for quality in the learning experience. There is true camaraderie among the students--they desire the best for all, with a willingness to help and hold each other responsible while showing an appreciation for the quality of Trinity’s faculty.
