Over the last 12 years I have gained vast experience designing and developing Spanish language curriculums at the college level. I have worked as a Spanish instructor at the University of Colorado at Boulder for 10 years. I have taught and designed classes for Beginning Spanish 1 (SPAN 1010), Beginning Spanish 2 (SPAN 1020), Intensive Second-Year Spanish (SPAN 2150), and Advanced Spanish (SPAN 3000). Heritage Spanish students at CU take the course SPAN 2150 to improve and develop their heritage linguistic abilities. Moreover, heritage students with advanced knowledge in grammar take the course SPAN 3000 to improve and develop writing abilities and learn about Latino culture. I also worked as a Spanish lecturer for the Anderson Languages & Technology Center (CU), teaching and designing the courses for advanced, intermediate, and elementary Spanish. I must also mention I have been the substitute lecturer for the course Spanish Phonetics and Phonology (Spanish 3050-001) at the University of Colorado at Boulder.
