Aprender requiere tres procesos
• Codificar
• Almacenar
• Evocar

La evocación ayuda a consolidar lo que sabemos y facilita futuras evocaciones.

Y evocar no es más que evaluarse.

"La única manera de saber si sabemos (hacer) algo es evaluándonos, es poniéndonos a prueba (haciéndolo)"

"Pero, además, evaluarse es en sí mismo una manera de aprender"

"La evaluación debe cumplir una función reguladora (durante). No sirve dar un feedback al final, cuando ya no hay nada que hacer."

De la presión y el juicio que supone la evaluación calificadora al aprendizaje que facilita librarse de las notas.

Seguimos a vueltas con las notas.

La cultura de la calificación promueve que el objetivo de los estudiantes sea la nota y no el aprendizaje.
Me lleva a la paradoja de la calificación. www.nachosm.com/blog-es/la-p...

"Evaluar es tomar evidencias del aprendizaje. Calificar es valorar esas evidencias convirtiendo la evaluación en sumativa. Si usamos esas evidencias para tomar decisiones y dar feedback, la evaluación es formativa" @hruizmartin.bsky.social en #researchED_Madrid

I was interviewed for my school's Newsletter and I translated it. #EduSky #MathSky

Excerpt from the interview highlighting a phrase from the book "Learning to love Math" that states "No other school subject pushes emotional buttons the way math does".

Cita de "How the brain learns mathematics" por David A. Sousa
"Students in the elementary grades are still interested in their studies, and the arithmetic they need to learn is achievable without too much effort. They generally maintain a positive attitude toward mathematics in these grades. But attitudes change when students get into middle school and high school, where mathematics is taught by subject-area teachers and the coursework is more demanding. Teachers now hear many students saying, “I don’t like math!” There are several reasons for this emotional response to secondary-level mathematics. One reason is due to what is generally termed “math anxiety.” We will discuss math anxiety in greater detail in Chapter 7. For now, we will note that anxiety triggers an increase in corti- sol—the stress hormone—in the blood, and that produces an unwelcome and uncomfortable mental state."

As the school adopts a comprehension-based approach for teaching maths, it was a surprise the resistance showed by a number of families.
The changes include using manipulatives and alternative algorithms to the traditional ones.
After reading to Judy Willis, I guess it's not surprising.
Cite from the book "Many parents of today's students learned math by doing worksheets and drills, and they expect the same for their children. Parents who were successful in math through repeated memorization skills (rather than strong concept development) may resent alternative math instruction, such as inquiry and manipulatives, for their children. A possible result is that some parents may feel frustrated when they can't help their children with the unfamiliar homework." Book cover of the book "Learning to love math" by Judy Willis

Hola! 👋
Estoy de acuerdo, @smaccarrone.bsky.social deja claro el mito de la dificultad, falta que convenzamos en clase de que pueden.
Por otro lado está esto otro de David A. Sousa en "How the brain learns mathematics"de cuando se acostumbran a mates mecánicas en primaria y luego se complican.
Fragmento del libro de David A. Sousa en el que se dice que en primaria las matemáticas requieren poco esfuerzo y luego en secundaria se complican.
