Teacher Review

Khan Academy has a collection of more than 5,500 videos and 100,000 practice problems covering K-12 math and select topics in science, history, business, art history and test preparation. It focuses primarily on content for students in the US schools, but it's a reliable source for anyone with a hunger to learn. Khan Academy is worth using if you're on a budget and want to get a customized plan with practice exams and lessons to help you ace the test. You can use Khan Academy both online and offline - the app allows you to download your favorite content to your phone and browse it later even without an internet connection. 

If you haven’t heard of Khan Academy already, we encourage you to try this free tool for both students and teachers. You need to know that this is an extension of the Khan Academy website, makers of Khan Academy Kids which is a non-profit, open source educational website with the aim of ‘changing education for the better by providing a free world-class education for anyone anywhere’.

Khan Academy allows you to watch more than 4,300 video lessons on topics including mathscience, economics, and humanities either by streaming them from the site or downloading them for later viewing or when you don’t have an Internet connection. Khan Academy specializes in teaching history, math, and science and suitable for students 14+. Khan Academy receives a 5 star EAS Certification and the EAS Recommended status making it one of the best educative apps on the market.

Salman Khan, an educator and former hedge fund analyst gave up his job and dedicated his time to start Khan Academy after uploading educational videos on YouTube to try and offer his young cousins a remote educational supplement. 

Is Khan Academy a reliable source?

Upon finishing our Khan Academy review, we believe this is one of the best educational apps on the market. Khan Academy is a simple learning app that is very easy to use. On opening the app you will see the menu on the left side with all the videos organized under 7 categories: Math, Science & Economics, Humanities, Test Prep, Partner Content, Talks and Interviews, and Coach Resources. At the time of this Khan Academy App review the app provides access to over 4,300 videos currently available on the Khan Academy website.  On choosing one of the above categories you will open a more detailed menu that includes, for example under Science & Economics, biology, chemistry, computer science and more others. You will find many subcategories and at all times you are shown how many videos are included under each of them.  

The videos are organised like mini lessons, most of them under 10 minutes. All of them are lectured and feature very useful and witty slideshow drawings. You also have underneath the video player an interactive transcript that, even though it doesn’t scroll down automatically while the video plays, makes it very easy to follow or to jump around specific topics in the videos. Students will find this very useful if they think the lecture is going to fast or if they will want to review just certain parts.

How much does Khan Academy cost?

Khan Academy is free to download! Learn almost any subject free of charge with this reliable education app! 

What are the benefits of Khan Academy?

After completing our Khan Academy app review we think that two of the most important features of this education app is the possibility to download the videos so you can watch them offline and the login function that allows you to access your profile.

Until recently the Khan Academy app wasn’t offering any practice exercises and students had to use the website to get to practice what they learn.  But at the moment students can practice their skills by accessing their account and opening the knowledge map where they will find a series of mathematical tests. Khan Academy offers an extensive content relating to Math and most of the exercises provided are intended to develop math skills (you get to try exercises like adding negative numbers, subtracting decimals, logarithms and many more). Students can check their profiles to view their history, achievements and other suggestions on what they could learn next.

Khan Academy app also offers mentors, parents and teachers a coaching tool that provides insight into a child’s progress. Teachers are offered ideas, materials and best practices for integrating Khan Academy into their classrooms. You can create classes, add students and the skills they’ve worked on and completed. Having the possibility of accessing lectures at home means that students who struggle to focus in the classroom can catch up quickly with the rest of the class by exploring the mini-lessons at home and at their own pace.

Final Thoughts

Our overall Khan Academy review is positive. At the time of this Khan Academy app review we found the lessons are accurate, easy to understand and very varied making it a good resource for all ages. Some videos took more to load than others and a back button in the account pages could be useful, but if you are a student who needs more help outside the classroom or just want to learn about subjects you are interested, Khan Academy app is an educational tool that will not disappoint. The app receives a 5 star EAS Certification and the EAS Recommended status.
