Estructura del curso

Este curso contiene 20 videos en vivo de LIVE de 1 hora. 16 son lecciones y 4 son análisis de examen donde se comentan los 4 exámenes de práctica de 1 hora del curso (tarea). Dos de nuestras Stars enseñan la clase conjuntamente. En total, hay más de 150 problemas.

Cada lección contiene distintos problemas diseñados para que sean desconocidos para ti, para inspirarte a imaginar tus propias soluciones. En el formato de clase de video en vivo de LIVE, tu propones ideas y pensamos juntos para inventar varias soluciones alternativas con las ideas propuestas en clase. Así participas activamente en el descubrimiento de las matemáticas.

Cada examen de práctica contiene 20 problemas. La mitad son de dificultad media y la otra mitad son más complejos.

I fall asleep to prof. loh music every night and listen to his ted talk every night

We appreciate how much [our son] is learning and growing in this class. Thank you for making the world a better place through math and kindness!

I have high respect for Po-Shen, and was hoping for a while to get a first-hand view of this approach to online classes. [My daughter] didn't really let me observe too much, but she did confirm that this class was better than any other online classes she's had, and better than some in-person classes too. That's very impressive. Great job, everyone involved!

Thank you very much for explaining [my son's learning situation] in detail… I asked him about this course and he expressed that he was very interested and enjoyed learning this course. The school had a test for the most recent class, so I watched the replay in the afternoon. I think he gained something from this course. Thank you teacher!

[My daughter] enjoyed really much all the sessions she attended, thank you for the great teaching and animation!

Thanks so much for the detailed class participation summary! It is very helpful! [My daughter] said the class is very useful and more interactive activities than other virtual class she had before!
