Ellen Key, aunque no era una pedagoga, tuvo un efecto extraordinario con sus ideas sobre la educación de los niños expresadas en su obra El siglo del niño en 1900. Ella creía que la vida del niño es lo más importante y debe estar por encima de la familia, la sociedad y el Estado, por lo que los niños deben tener la mayor libertad en su educación y desarrollo personal de acuerdo con las leyes de la naturaleza.

Mirella era bella
Este cuento describe la relación entre Gustavo y Celeste. Celeste es una mujer hermosa que usa su belleza para obtener regalos y lujos de Gustavo. Cuando los negocios de Gustavo empiezan a ir mal, Celeste quiere tener un hijo, pero Gustavo decide terminar la relación. Celeste reacciona con furia, gritando e insultando a Gustavo.
My own reflection 1
The document discusses the origin and history of the English language. It explains that English began as a Germanic dialect spoken in a small part of the British Isles but has since become one of the most widely spoken languages worldwide. The development of English started around 3,000 years ago with the arrival of the Celts and was later influenced by Latin from the Romans. Over time, English underwent internal and external changes and can be divided into periods like Old English and Modern English. Learning about the origin and evolution of English provides useful context for teaching the language and answering students' questions.
