Shadowing Practice: Crash Course Scientific Thinking Preview - Learn English Speaking with Video
Creando lección...
1
Science is everywhere.
2
And you're interacting with it all the time.
3
In school, sure.
4
But also in the news.
5
On your For You page.
6
Around your dinner table.
7
And right here on YouTube.
8
That's a good thing.
9
Science is one of the coolest things our species has going for it.
10
Right up there with art, literature, and bidets.
11
But when it's coming at us all the time from all kinds of places, it can be hard to make sense of it.
12
Much like a bidet.
13
These days, we're bombarded by news stories about science.
14
Our feeds are full of everything from nutrition to climate change.
15
On top of that, our own brains are hardwired to deceive us.
16
We all have cognitive biases that, when left unchecked, can make it even harder to know if something is supported by evidence or not.
17
But science isn't just a buzzword.
18
It's a unique way of uncovering knowledge that's dynamic, communal, and self-correcting.
19
And it's one of the best ways we have of understanding what's actually going on around here.
20
Thinking scientifically helps us push past biases and agendas and clickbaity headlines towards the elusive, capital T, truth.
21
Hi, I'm Hank Green.
22
I started making YouTube videos in 2007 with my brother, John.
23
Now I am a go-to internet science guy, having produced and hosted literally thousands of videos and podcasts all across the internet.
24
I also co-founded Complexly, which produces this show, Crash Course, as well as SciShow and nearly a dozen other educational YouTube channels.
25
In seven episodes, Crash Course Scientific Thinking will explore the foundational principles that underlie scientific thought.
26
We'll pull back the curtain on peer review, take a magnifying glass to scientific sources, unpack big ideas like consensus,
27
and consider how what we know about the world grows and changes over time.
28
And we'll explore scientific experiments, processes, and discoveries to figure out how science has impacted our lives.
29
By the end, you'll be able to think more critically about basically everything from
30
From your science textbooks to the news on your feed to that guy who keeps yelling at you about science on TikTok.
31
We'll learn how to sift through information wherever it comes from, to inch ourselves closer to a nuanced, shared, scientific understanding of the world.
32
And you'll walk away a more savvy consumer of science information.
33
So join us here next time when we will ask a big question… can we trust our own brains?
34
This episode of Crash Course Scientific Thinking was produced in partnership with HHMI Bio Interactive, bringing real science stories to thousands of high school and undergrad life science classrooms.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
