Hello fellow linguaphiles! My name's Osvaldo but people usually call me Valdo. I could also be called 偶巴多 (中文), Oswald (auf Deutsch), or Освальдо (по-русски). My native language is Spanish but I also have a native fluency and proficiency in English. I have a Bachelor's degree in Philosophy and a Master's degree in Linguistics. I enjoy travelling, exercising, running, kayaking, dancing, and learning new languages. I've lived in Puerto Rico for most of my life but I also spent some time living abroad in Beijing, China and in Berlin, Germany.Mostrar traducción
Yo como profesor
I have a TEFL certification from ITA (International TEFL Academy) and I've been teaching ESL since 2015. I also have a CIPELE certification from the University of Salamanca. I've taught Spanish since 2021. I have experience working with students of different ages and levels of proficiency. I've taught children, teenagers, and adults with beginner, intermediate, and advanced levels of proficiency. I have experience teaching online, at language learning centers, and at traditional schools. I've had group classes and individual 1-on-1 classes too. I've also taught basic Mandarin Chinese at a local university.Mis clases y método de enseñanza
I use all kinds of tools and resources to teach classes online. I like to have my students do different types of exercises to help them improve their language skills (reading, writing, speaking, listening, grammar, and comprehension). I've used various platforms like zoom, skype, google hangouts, kahoot, and youtube. I have also used several documents like ppt's, pdf's, newspaper articles, and word documents. During class, my students do listening comprehension exercises, conversational activities, reading comprehension activities, grammar exercises, among others. If you wish, we can also use a book for our classes but we need to come to an agreement beforehand.Mi material didáctico

Valdo is a phenomenal teacher - attentive and creative. I have taken 3 weeks of lessons and see a dramatic improvement in my comfort with speaking and understanding Spanish.

I am on a mission to learn Spanish and Valdo is the best! I took a while looking at other teachers' profiles and chose Valdo because of his qualifications and excellent reviews. I look forward to my lessons every week, each time there is new material or we are reviewing to really let it sink in. Lots of variety, and he provides resources so that I can continue practicing Spanish outside of class as well. Valdo is a fantastic teacher, and just a really cool person in general.

1000% an amazing experience! Osvaldo was super chill, explained things well, and help put together a plan that was personalized for me. He took the time to get to know more about me before jumping into a plan which I really appreciated as well. Excited for the journey to come!

Valdo went over his teaching techniques, asked about my expectations, and also went over some vocabulary and questions to gauge my knowledge of Spanish. It was a great introduction. I already booked my next lesson.
