Julio Delgado
Spanish || 10th
Digital Portfolio

My name is Julio Delgado and I am a Spanish teacher at High Tech High. I have an undergraduate degree in education and Spanish literature from the National University of El Salvador. I also have a California credential to teach literature and Spanish language at a high school level and two years of graduate courses in Special Education. I have taught bilingual elementary school for almost five years and Spanish language and literature at a high school in Los Angeles. I also have over 10 years experience coaching soccer, from my children's teams to a varsity high school team.

Before becoming a teacher I had the privelege to work with many different communities. In college, I designed and implemented a literacy project for adults and children in a Mayan community in El Salvador. I also conducted an oral history project about the struggles of refugees fleeing from a war zone within El Salvador.

As a member of the Central American Refugee Comittee in Los Angeles, I traveled across the US participating in a national educational campaign for peace and human rights in Central America. Also, I have worked in a homeless children's shelter for the International Human Rights Center in Los Angeles and worked with adults with severe disabilities as an independent leaving skills coach in San Francisco.

Anne Duffy
Math|Science || 10th
Digital Portfolio

I grew up in Denmark but have lived in the San Diego area since 1989. I received my Bachelor's degree in chemistry from UCSD. After acting as an undergraduate teaching assistant at UCSD, I fell in love with teaching. I chose to stall my doctoral degree in chemistry and pursue a Master's degree in chemistry (also at UCSD) while researching teaching options at various levels.

Upon completing my Master’s, I went to what my chemistry lab colleagues called “the dark side” when I chose to pursue a doctoral degree in math and science education instead of organic chemistry. I have been teaching in various capacities since 1995 with ages ranging from Kindergarten science outreach, 4th and 5th grade math enrichment to organic chemistry students in college.

I know that I have found a satisfying career not just because I love teaching math and science at all levels but because I would do it for free. Shh. That’s our little secret.
