I’m a teacher, focusing on Spanish and English, as well as an academic researcher.

Hernán Rosario has a PhD from the University of Florida. During the past years his work has focused on teaching English and Spanish in various universities and colleges. His research focuses on the contact of Spanish and English in Puerto Rico, loan words and phonetic perception.
Hernán Rosario is originally from San Juan, Puerto Rico. He received his BA in Spanish High School Education from the University of Puerto Rico, Río Piedras Campus, where he also obtained his MA in Linguistics.
As a facilitator in the classroom, I provide guidance towards the student's self-discovery of the language and path to improvement. I value and consider the specific needs of the students in each course, adapting my teaching methods accordingly. This student-centered approach has been successful, as evidenced by consistently positive student evaluations and many students choosing to take multiple courses with me.
My teaching philosophy is grounded in a sociolinguistic and variationist approach, acknowledging the lexical, phonetic, syntactic, and pragmatic differences that exist across the diverse dialects of each language. I incorporate knowledge from different dialects to help students understand Spanish or English’s diversity, preparing them for real-world interactions with speakers from various cultural backgrounds.

Technology plays a crucial role in my teaching methodology. I utilize tools like Praat for acoustic analysis, allowing students to visualize and understand phonetic concepts across different languages. This hands-on approach helps students better comprehend linguistic variations and challenges potential prejudices about different the varieties of each language.
Beyond language instruction, I am committed to supporting students' professional development, guiding them toward study abroad opportunities and career paths where second language proficiency is valuable. My classroom environment encourages open communication and trust, enabling meaningful mentorship relationships with students.
