Today we’re happy to announce that learners around the world can now access Khan Academy resources in Hindi! If you speak Hindi, you can learn math through our video lessons and practice problems mapped to India’s NCERT curriculum.

Wherever you are - Mumbai, Jaipur, a village in Haryana, or anywhere else around the globe - we believe you deserve the opportunity to learn at your own pace and in your own language.

Khan Academy in Hindi brings us one step closer to our mission of a free, world-class education for anyone, anywhere, and we thank our friends at Central Square Foundation for helping to make this possible. We hope you enjoy Khan Academy in Hindi!

At Khan Academy, we know how important computer science and computer programming are - in fact, the Khan Academy website wouldn’t exist if Sal didn’t know how to code! That’s why we participate in Code.org’s Hour of Code campaign every year during Computer Science Education Week - we want to make sure every student gets to learn the basics of coding.

From December 7 to 13, millions of students around the world will be learning to code - in classrooms, in after-school clubs, and with parents at home. We invite you to join the #HourOfCode movement by learning to code here on Khan Academy, picking from one of our three tutorials:

Hour of Drawing with Code: Learn to program using JavaScript, one of the world’s most popular programming languages, via two great options:
- Drag-and-drop: block-based coding for those with less typing experience or on tablet devices (ages 8+).
- Typing: keyboard-based coding (ages 10+).

Hour of Webpages: Learn to make your own webpages using the basics of HTML and CSS (ages 10+).

Hour of Databases: Learn the fundamentals of databases using SQL to create tables with data and query the data (ages 12+).

We hope you’ll join us in celebrating Computer Science Education Week and spend an hour on Khan Academy learning to code!

Here at Khan Academy, we are continually expanding our library of videos, text explanations, and practice questions across many subjects. To help guide us in creating content that truly meets student’s needs, we assembled a Student Advisory Council who have been working with Khan Academy for the past 2015-2016 academic school year.

The Student Advisory Council is a selective program that comprises high school and college students who care about learning and want to help other students succeed.

We’re excited to announce that Duck Duck Moose, an award-winning developer of educational apps for young children, is now part of Khan Academy.

We believe every child should have access to the best learning resources, so we’re making all 21 of Duck Duck Moose’s apps free.

Download the apps for Android from Google Play

Download the apps for iPhone or iPad from the App Store

Early childhood learning is a natural next step for Khan Academy. It allows us to reach children at a younger age and begin to have an earlier impact on basic literacy and math skills. We’re thrilled to enter early childhood learning with Duck Duck Moose as our partner. We’ve long admired their whimsical children’s apps, which have been downloaded more than ten million times and receive rave reviews.

In addition, Duck Duck Moose’s nine-person team is joining Khan Academy to lead a new initiative to develop early learning products for young children. This is possible thanks to philanthropic investment firm Omidyar Network, the first underwriter of this new initiative. Like us, Omidyar Network believes early childhood education is critical for long-term success. Together we hope to have a lasting impact on the lives of children.

We’re thrilled to welcome Duck Duck Moose to the Khan Academy family, and we hope you love their apps as much as we do.

Onward!

Estamos progresando continuamente en nuestra misión de proveer una educación gratuita y de clase mundial para cualquier persona, en cualquier lugar. Nuestros contenidos y productos ayudan a millones de estudiantes y maestros alrededor del mundo a practicar y explorar habilidades académicas a su propio ritmo y en sus propios términos.

Sin embargo, estamos a medio camino. Mientras continuamos expandiendo nuestros esfuerzos en los Estados Unidos y en otros países, es importante que nuestros recursos de alta calidad sean accesibles para cualquiera. A pesar de las tendencias globales que indican que las personas están entrando al mundo digital más rápido que nunca antes, todavía existen dos principales barreras para lograr el acceso global a la educación en línea: infraestructura básica y costo de datos de navegación.

En Khan Academy, nos dedicamos a reducir las barreras para el acceso universal a la educación. Hoy, los usuarios Telcel en México pueden navegar en las aplicaciones móviles de Khan Academy en español y en la página es.zero.khanacademy.org sin consumir sus datos de navegación de sus planes de pre pago o pos pago, gracias a nuestra alianza con la Fundación Carlos Slim y Telcel. El costo de los datos de navegación no debería ser una limitante al acceso a la educación básica, que creemos es un derecho humano fundamental.

Da clic aquí para ingresar a los recursos educativos de Aprende.org.

Este es el primer esfuerzo en lo que imaginamos puede ser algo más grande: los estudiantes alrededor del mundo con acceso a un tutor gratuito, 24/7, justo en la palma de sus manos. No podremos llegar ahí sin la ayuda de socios alineados a nuestra misión alrededor del mundo. Por eso, estamos compartiendo los principios de nuestro programa de alianzas con un profundo compromiso en poner a los estudiantes primero y estamos emocionados en colaborar con socios que creen que los servicios públicos, como la educación, son críticos para avanzar en el crecimiento humano, económico, y social.

Los principios de la alianza tasa cero de Khan Academy

Estamos colaborando con operadores de telecomunicaciones para que Khan Academy sea tasa cero en dispositivos móviles. Esto significa que nuestros aliados no cobrarán datos de navegación a los usuarios. Nosotros exploramos estas oportunidades de forma puntual. Compartimos y hemos adaptado muchos de nuestros principios directamente de Wikimedia y estamos interesados en desarrollar alianzas y colaboraciones con otras organizaciones educativas sin fines de lucro interesadas en incrementar el acceso en formas similares. Nos regimos por los siguientes principios cuando consideramos llevar a cabo una alianza:

Cláusula de no competencia: El objetivo principal de Khan Academy es proveer acceso a recursos educativos de alta calidad y gratuitos. Estamos interesados en ayudar a organizaciones con la misma misión no comercial de concretar esto

- Los operadores no tienen control editorial de nuestro contenido: El contenido es creado y seleccionado por Khan Academy, en asociación con nuestros aliados. Los operadores no tienen control sobre qué contenido ofrecemos. Ningún operador tiene derechos exclusivos perpetuos

Nuestro objetivo es maximizar el acceso del estudiante, y como tal no ofrecemos derechos exclusivos en perpetuidad a ningún operador, nunca: Esperamos asociarnos con muchos operadores alineados a nuestra misión para maximizar el impacto para los estudiantes

Licencia de uso de marca limitada: Los operadores obtienen una licencia para usar nuestra marca para promover Khan Academy. Ellos no pueden usar nuestras marcas para sugerir que están patrocinados, aprobados o apoyados por Khan Academy

Sin recolección de información personal: Los operadores reciben direcciones IP que serán tasa cero solo para identificar apropiadamente el tráfico en Khan Academy. Los operadores no pueden recolectar información personal acerca de los estudiantes, más allá de monitorear cuáles de sus usuarios están usando Khan Academy.

Sin vinculo comercial: El acceso a Khan Academy a través de programas de tasa cero no puede ser parte de un paquete comercial de un operador

Como una organización sin fines de lucro, nosotros observaremos detenidamente el impacto que este programa tenga en los estudiantes en México. Esperamos poder compartir nuestros aprendizajes. Estamos particularmente interesados en aprender qué tan viables son este tipo de programas durante los próximos cinco a diez años, mientras el costo por datos móviles baje y el acceso a Internet aumente. Por ahora, estamos emocionados en incrementar el acceso de una forma pequeña pero importante para los estudiantes en México.

Los usuarios Telcel en México ahora pueden navegar en Khan Academy en dispositivos móviles a través de es.zero.khanacademy.org o en nuestras aplicaciones para Android y iOS llenas de ejercicios, videos y artículos de un amplio rango de materias. Este trabajo no hubiera sido posible sin el generoso apoyo de nuestro socio, la Fundación Carlos Slim y Telcel. Para ingresar a más contenido educativo de calidad y sin cargo de datos visita Aprende.org

Si tu organización está interesada en asociarse con Khan Academy en una iniciativa similar, por favor envía tus propuestas a partnerships@khanacademy.org.


English

We’re making continual progress toward our mission of providing a free, world-class education for anyone, anywhere. Our content and products help millions of students and teachers around the globe find, practice and explore academic skills at their own pace and on their own terms.

But we’re only part way there. As we continue expanding our efforts in the US and beyond, it’s critical our high-quality resources be accessible to everyone. And despite global trends that indicate people are coming online faster than ever before, there are still two major barriers to equalizing global access to online education: basic infrastructure and the cost of data.

At Khan Academy, we’re dedicated to reducing barriers to equal access to education. Today, Telcel customers in Mexico can access Khan Academy’s mobile apps in Spanish and the website es.zero.khanacademy.org without consuming data from their pre-paid and post-paid plans, thanks to partnership with Carlos Slim Foundation and Telcel. Data costs alone should not limit access to a basic education, which we believe is a fundamental human right.

This is the first effort in what we imagine can be something bigger: learners around the globe with access to a free, 24/7 tutor, right in the palm of their hands. We won’t get there without the help of mission-aligned partners around the globe. As such, we’re sharing our program principles to signal both our deep commitment to putting learners first and our excitement to collaborate with partners who believe public services like education are critical for advancing human, economic and societal growth.

Khan Academy Zero Rating Partnership Principles

We’re collaborating with telecom carriers to zero rate Khan Academy on mobile devices. This means our partners sponsor data charges to make them free for learners. We examine these opportunities opportunistically. We share and have adapted many of these principles directly from Wikimedia and are interested in developing partnerships and collaborations with other education nonprofits interested in increasing access in similar ways. We abide by the following principles when considering a partnership:

Non-competitive clause: Khan Academy’s main goal is to provide access to high-quality educational resources free of charge.  We’re interested in helping ensure organizations with the same non-commercial mission can do so as well.

Carriers do not have editorial control of our content: Content is created and curated by Khan Academy, in association with our partners. Carriers have no control over what content we deliver. No carrier has perpetual exclusive rights.

Our goal is to maximize access for the learner, and as such we do not offer exclusive rights in perpetuity to any carrier, ever: We hope to partner with many mission-aligned carriers to maximize the impact for learners. 

Limited trademark license: Carriers get a license to use our trademarks to promote Khan Academy. They cannot use Khan Academy trademarks to suggest they are sponsored, approved, or endorsed by Khan Academy.

No collection of personal information: Carriers receive the IP addresses of sites that will be zero-rated only to appropriately identify Khan Academy traffic. Carriers cannot collect personally-identifiable information about our learners beyond monitoring which of their users is using Khan Academy.

No commercial bundling: Access to Khan Academy through zero-rating programs cannot be part of or combined with a carrier’s commercial bundle.

As a non-profit, we will be closely watching the impact this program has on learners in Mexico. We look forward to sharing what we learn. We’re particularly interested in learning how viable these kind of programs will be over the course of the next five to ten years as the cost of data declines and access to the Internet increases. For now, we’re thrilled to increase access in a small but meaningful way for learners in Mexico.

Telcel users in Mexico can now access Khan Academy on mobile devices via es.zero.khanacademy.org or our Android and iOS apps, complete with exercises, videos and articles across a wide range of subjects. This work would not have been possible without generous support from our partners, the Carlos Slim Foundation and Telcel. To access more great educational content completely free of charge, visit Aprende.org

If your organization is interested in partnering with Khan Academy on a similar initiative, please send inquires to partnerships@khanacademy.org.

Announcing our 2016 Talent Search winners in the US and Canada

$

At Khan Academy, our mission is to provide a free, world-class education for anyone, anywhere. Our mission is ambitious, and we can’t do it alone. We need great explainers to create instructional videos, practice exercises, and reference articles to contribute to our growing library of content.

That’s why we ran the Khan Academy Talent Search again in the US and Canada this June - to find great video creators and amplify their voices. (We’ve also got a talent search in India! Click here for information.) We asked this year’s contestants to focus on a range of subjects from biology and psychology to geography and statistics. We received 1,300 video applications, and were blown away by the quality, passion, and ingenuity.

After reviewing all applications, we selected ten winners: one overall winner and nine finalists.

We were looking for videos that explain academic concepts with clarity and depth, are friendly and conversational, and laser-focused on helping students when they most need guidance - whether they are learning a concept for tomorrow’s test, completing their homework, or reviewing what they learned in class. These 10 videos clearly exemplify these qualities:

Scroll down to see all 10 videos. The overall winner receives a $3,000 cash prize and finalists receive $300. All winners are considered for content creation opportunities at Khan Academy.

Although our talent search is over in the US and Canada, we’re still looking for great creators to bring content to learners around the world. Check out our careers page for current job openings on our content team.  As previously mentioned, we’re running an India Talent Search to identify great video creators who can create content aligned to India’s academic standards.

Check out the 10 winning videos!

 

Overall winner Alison Caldwell: Doctoral student in neuroscience

Parts of the Brain

Alison’s video description: The brain is a complex organ, and even though it all kinda looks the same, it turns out that different parts of the brain do different things. In this video, we’ll go over all of the major parts of the brain, including the occipital, temporal, parietal, and frontal lobes. And we’ll even cover some of the other structures that get taken for granted. Get ready to fall in lobe!

Why we selected this video as the overall winner: ‘Parts of the brain’ covers the academic concepts deeply and rigorously, and Alison’s delivery throughout the video feels friendly and conversational while staying focused on what a student needs to know for class. You might have guessed that one of the reasons we selected this video as the overall winner is its high production values (engaging special effects, beautiful brain illustrations, etc.). While these certainly make the video enjoyable to watch, high production values aren’t a factor in our scoring. We look for videos that display exceptional clarity, approachability, and a focus on student needs - all qualities this video exemplifies.

Meet our nine Talent Search finalists!

Abraham Feinberg: College science teacher and data analyst

Nature vs. Nurture - Part 1

Abraham’s video description: Are your behaviors a fixed, inevitable result of your genes? Or are they the result of the people and objects that surround you? In this video, we’ll take a first look at the concept of Nature vs. Nurture, and we’ll try to get a beginning idea of why it’s such an important issue in many different areas of psychology (and everyday life!).

Check out more videos by Abraham.

Alexandra Evans: Policy instructor, Foreign Service Institute

Writing in the Ancient Near East

Alexandra’s video description: People have been drawing pictures for tens of thousands of years, but when did we really start to write things down? How did we develop written words from pictures? In this video, we’ll take a look at the very first writing systems, Sumerian cuneiform and Egyptian hieroglyphs, and we’ll trace how pictures evolved into written words.

Check out more videos by Alexandra.

Brian Macon: Full-time faculty, full-time father and husband, part-time PhD student

Confidence Intervals and Central Limit Theorem

Brian’s video description: What is the connection between the Central Limit Theorem and Confidence Intervals? In this video we will use a computer simulation to answer that question. The simulation will help us visualize the nature of sampling distributions as we begin our conversation about using estimates to make future predictions.

Check out more videos by Brian.

Jay Lin: Medical student and educational video producer

Neurotransmitters

Jay’s video description: How exactly do drugs affect the brain? This video will go over the normal chemical signaling in brain cells, and then explore the different ways drugs can change this normal signaling.

Kelly Squires: Retired middle school teacher

Plate Tectonics

Kelly’s video description: Whether we’re aware of it or not, the earth’s crust is in a constant state of motion. A whole lot of colliding, dividing and sliding of massive chunks of lithosphere called plates, is happening very slowly but surely, right this very second. The reason for this remarkable movement is plate tectonics. In this video, we’ll explore the cause of plate tectonics, the major plates found throughout the earth and the various landforms such as mountain ridges, valleys, volcanoes and faults that result from the plates’ movement.

Robert Lochel: High school math teacher

Chi-Squared Goodness of Fit Tests

Robert’s video description: Are hospital births equally distributed through the week, or are some days more likely? A chi-squared goodness-of-fit hypothesis test is used to compare the variability present in the data to what could reasonable occur by chance alone, and the big ideas behind these categorical tests are explained.

Check out more videos by Robert.

Finalist: Ron Maxwell: Middle school science teacher

Moon phases explained- middle school level

Ron’s video description: A simple talk to help you learn the phases of the moon and the way the moon phases happen…

Check out more videos by Ron.

Finalist: Sonal Nalkur: Visiting Assistant Professor of Sociology at Emory University

Gender, Norms, and Occupations

Sonal’s video description: Why do some occupations seem to have a higher proportion of men or women? And does a person’s gender always have implications in the workplace? Many sociologists are curious to understand the reasons why the labor market looks the way it does. We also want to understand the specifics about why some people might be excluded or treated differently in the workforce. In this video, you’ll be introduced to some of the concepts that allow sociologists to ask bigger questions about how gender might operate in various occupations.    

Finalist: Steve Yang: Recent graduate of Rensselaer Polytechnic Institute

Bernoulli’s Equation Revisited

Steve’s video description: Engineering principles are often built upon concepts that you may have already learned in math and physics. In this video, we’ll see how we can adapt and expand the energy form of the Bernoulli’s Equation to the hydraulic head form to better suit the needs of engineers.

Check out more videos by Steve.

Announcing Free LSAT Prep for All

$

We’re proud to announce we’ll soon offer free, personalized LSAT prep for all.

Every year, more than 100,000 people take the LSAT, the Law School Admission Test. Many test takers have traditionally paid for test prep, which can cost hundreds or even thousands of dollars.

We’re excited to offer a free LSAT practice program designed to help students with the skills they find challenging so that they can show up on test day ready to rock the LSAT.

What’s more, we’re doing this by partnering with the maker of the LSAT, the Law School Admission Council. By working with the maker of the exam, we can help many more people learn the skills they need to do well on the LSAT, in law school, and their careers.

We’re honored the Law School Admission Council has chosen to partner with us, and we’re excited to work together to help level the playing field.

Today’s announcement continues our tradition of providing free, official practice for standardized exams. In 2015, Khan Academy launched free Official SAT Practice with the maker of the SAT, the College Board. More than three million students have used Official SAT Practice at roughly equal rates across income levels, race, ethnicity and gender.

As always, our mission is to provide a free, world-class education for anyone, anywhere. We think free LSAT prep aligns perfectly with our goals. Look for it on Khan Academy in late 2018.

Studying for the SAT for 20 hours on Khan Academy associated with 115-point average score increase

$

We’re excited to announce today that studying for the SAT for 20 hours on Khan Academy’s free Official SAT Practice is associated with an average score gain of 115 points. That’s nearly double the average score gain compared to students who don’t use our free test prep.

Official SAT Practice is free for everyone and personalized for each student. Start getting ready for the SAT today! We think a 115-point score gain can make a real difference when applying to college.

If you don’t have 20 hours to practice, don’t worry. Shorter periods of time also correlate with meaningful score gains. Six hours of study on Official SAT Practice is associated with an average 90-point increase—no small bump.

We’re also excited that more than 16,000 students from the class of 2017 who used Official SAT Practice improved their scores by more than 200 points. Way to go!

Together with the College Board—the maker of the SAT—we studied data from nearly a quarter million high school students from the graduating class of 2017 who took the PSAT/NMSQT and the new SAT in the past year. Score gains were consistent across genders, family income levels, races, ethnicities, high school GPAs, and parental education levels.

Since its launch in 2015, Khan Academy’s free Official SAT Practice has been used by more than 3.7 million students. We’re glad so many people are finding it helpful!

* Nearly 40% of all test takers report using our free Official SAT Practice, making it the number one tool for SAT prep.

* Twice as many students report using Khan Academy as paying for commercial test prep.

Khan Academy and the College Board developed Official SAT Practice to create personalized tools to help all students, regardless of income level or background, prepare for the SAT and college-level courses.

Official SAT Practice reinforces what students are learning in school by helping them focus on the knowledge and skills most essential for college. And it’s free, for everyone, forever.

The Khan Academy team creating AP materials includes current and former AP teachers. External reviews by members of the AP community ensure all AP materials on Khan Academy align with the AP Program’s rigorous academic standards.

Our team is also working to add practice exercises to every AP course and will be making them available as soon as they’re ready.  (Our AP Calculus courses already have exercises.)

AP teachers, your insights and observations from using Khan Academy are the most valuable feedback we receive. Our goal is to make our lessons helpful for both teachers and students, and we can’t do it without you. Please send us your thoughts, no matter how big or small.

Here’s a video of an AP teacher who uses Khan Academy in the classroom. Bill Scott is the chair of the math department at Phillips Academy in Andover, MA.

Khan Academy launches free Official LSAT Prep

Many LSAT-prep courses can be expensive, leaving a lot of law school hopefuls feeling out of luck. Not anymore.

Thanks to Khan Academy’s new Official LSAT Prep, anyone interested in going to law school can now prepare for the LSAT—the law school admission test—with a personalized study plan entirely for free.

Khan Academy collaborated with the Law School Admission Council, the maker of the LSAT, to design the first free and official test prep program for the LSAT.

The aim of Khan Academy Official LSAT Prep is to help aspiring law students build the skills and confidence they need to succeed on test day—all on their own schedule.

Official LSAT Prep diagnoses each student’s strengths and weaknesses and creates a tailored practice plan. Each student sets a score goal. Then, the program guides students through lessons and practice questions at just the right level to help them work toward that score. Videos, articles, and explanations cover every concept on the LSAT. Through it all, we provide regular updates, so students can track their progress.

Today’s announcement marks the launch of Khan Academy’s second official test prep for critical standardized exams. In 2015, Khan Academy launched Official SAT Practice with the College Board. Nearly six million people have used Official SAT Practice, and research shows that practice on Khan Academy advances all students regardless of high school GPA, gender, race, ethnicity, or parental education level.

We’re honored to provide free and personalized test prep for all and excited to help aspiring law students pursue their dreams.

The 2017 Khan Academy annual report is here! As a nonprofit organization, we’re grateful for our donors and honored to share the work they make possible. We’re also excited to celebrate the success of students and teachers who used Khan Academy in 2017.

Here are a few highlights:

• School districts across the country and around the world partnered with Khan Academy in 2017 to bring our free resources into classrooms, especially those with traditionally underserved and underrepresented demographics. We’re proud to work with teachers to provide in-class practice, homework, review, and test prep.

• We announced that practicing for the SAT on Khan Academy is associated with significant score gains. Research shows studying for the SAT for 20 hours on Khan Academy is associated with an average score increase of 115 points, nearly double the average score gain of students who don’t use Khan Academy.

• More than one million students and 23,000 teachers took part in LearnStorm, our first-ever national education challenge. Students logged 90 million minutes of learning! We continue to have an impact where it’s needed most: 55% of students who participated in LearnStorm in 2017 attended schools where a majority of students qualify for free and reduced-price lunch.

2017 was a big year for Khan Academy. As we look ahead toward the second half of 2018 and beyond, we’re energized to continue our work to support students and teachers around the world. Learn more about our work in individual school districts like in Long Beach, California  and across countries like  India and Brazil.

Our mission of providing a free, world-class education for anyone, anywhere is made possible by generous support from donors like you. Please consider making a donation today. Thanks for your support. Onward!

Khan Academy introduces something big for little learners

Today we’re announcing something entirely new: an education program for children ages two to five designed to inspire lifelong learning.

Khan Academy Kids is available now in the App Store and in beta for Google Play and the Amazon Appstore. Like all our educational offerings, Khan Academy Kids is 100% free. It’s part of our mission of providing a free, world-class education for anyone, anywhere. (We’re a proud 501©(3) nonprofit organization that offers all our resources free to students and teachers.)

With thousands of original activities, books, videos, and lessons, Khan Academy Kids combines subjects like math and reading with creative activities like drawing and storytelling.  

We worked with childhood experts from the Stanford Graduate School of Education and children’s book authors to create the app. Our curriculum and library of books teach academic skills as well as social-emotional development and healthy habits.

Animated animals from around the worlds—aren’t they cute?—guide children through educational materials at just the right level for them.  As kids learn, they collect bugs, hats, and toys for their favorite characters.

While many early learning apps focus on a narrow skill area, Khan Academy Kids is a complete learning experience across multiple subjects that is aligned to the Head Start Early Learning Outcomes Framework for preschool-aged children and Common Core State Standards for kindergarten-aged children. The program is designed to adapt over the years as a child grows.

Khan Academy Kids was created by our award-winning early learning team,  whose educational materials have won 21 Parents’ Choice Awards, received 18 Editor’s Choice Awards from Children’s Technology Review, and been voted the best children’s app at the International Consumer Electronics Show.

Parent participation is a key component of the Khan Academy Kids experience. Parents can engage in learning activities with their child, and we encourage moms and dads to read our interactive books out loud. Parents can also view their child’s progress on activities in the Library and set up accounts for multiple children, all for free.

Extra special thanks to the Khan Academy Kids partners who provide free learning materials: Super Simple Songs® from Skyship Entertainment™, Bellwether Media, and National Geographic Young Explorer Magazine. We’re grateful for their contributions!

Khan Academy Kids is made possible through generous support from Omidyar Network and Windsong Trust as well as kind donations from people like you. Thank you for your support, and onward!

Have you seen our new look?

We’re delighted to share the new logo that you’ll begin seeing across Khan Academy’s offerings in the coming days:

image

Our logo is new, but it reflects Khan Academy’s core values, which haven’t changed over time. Its shape and bright color reflect the joy of learning and the transformational power of education. The hexagon is a fundamental building block in math, nature, and art. And, we’ve retained the leaf symbol from our previous logo—a classic metaphor for personal growth, which we care deeply about.

Our new logo is a celebration of the passion for learning that we value as an organization and a community.

We’d love to hear what you think in comments. If you plan to use the new logo in your classroom, we’d love to hear how.

You might be wondering why we updated our logo. It’s pretty simple: Khan Academy is always growing and improving, and we need a logo that keeps up. We’ve evolved from a single website for desktops to multiple apps available across many devices. In our early days, we were known for math videos, but today we offer personalized learning across many subjects and every grade. Just this week we launched a new mastery learning system and new lessons for back to school!

Our new logo is flexible enough to work in a variety of settings. We think it looks great on devices, dashboards, app stores, laptops, and desktops. And, we love using it across our many platforms.

As you’re using Khan Academy to learn or to teach, we hope you’ll enjoy seeing our new logo out of the corner of your eye. Thanks for being part of a terrific community that celebrates learning and growth. Onward!

Our new, free, educational program, Khan Academy Kids, is designed to inspire young children to become learners for life. The app seamlessly intertwines animation and puppetry from Super Simple Songs® with interactive, educational activities covering early literacy, math, language arts, creative thinking, and social-emotional skills.  

Khan Academy is thrilled to partner with Skyship Entertainment™, the creator of the beloved Super Simple Songs.  “We are excited to collaborate with Skyship because of our shared commitment to making sure children everywhere have access to a quality education,” said Caroline Hu Flexer, head of Khan Academy Kids.  

Skyship Entertainment was started by two teachers who had the idea of combining favorite children’s songs with learning. “Our focus has always been making learning simple and fun, so we’re thrilled for Super Simple Songs to be part of Khan Academy Kids,” said Skyship Entertainment cofounder Troy McDonald. “We can’t think of any organization more passionate about education than Khan Academy.”

Super Simple Song’s beloved children’s classics are integrated into a wide range of educational activities in Khan Academy Kids to create a unique learning experience. Below are examples of what kids and parents can expect to see in the app:

Practice adding and subtracting with “Five Little Ducks”.

LearnStorm, our free back-to-school program, is back for a second year and open for teacher registration!

LearnStorm gives teachers a powerful tool to jumpstart the school year. Teachers can assign personalized practice and research-backed growth mindset activities that teach students how the brain gets stronger and smarter with new learning.  We’re proud to have worked with PERTS, a Stanford research center, on this year’s expanded growth mindset curriculum.

Students get real-time feedback and master skills as they progress through LearnStorm. Together, teachers and students celebrate progress on an interactive tracker, unlocking individual and class prizes as they go.

Watch some very excited students celebrating their LearnStorm success.

LearnStorm runs Tuesday, September 4 through Friday, November 9. Teachers can easily enroll using a Khan Academy account.

Last year, LearnStorm reached nearly one million students and 24,000 teachers in the US, with schools in all 50 states participating. Approximately 98% of teachers surveyed said they plan to use LearnStorm again this year. In pilots of LearnStorm, 96% of students reported their learning confidence increased while using Khan Academy.

LearnStorm is made possible through the generosity of MathWorks, a Massachusetts-based developer of software for scientists and engineers and a sponsor of LearnStorm.
