You can monitor your own progress and set goals for yourself in your dashboard, which prominently displays the badges you've won and your "energy points."Įxpand your programming horizons with CodecademyĪs much as I appreciate Codecademy's polished interface and interactive tutorials, more than once I was stymied by the lack of help when the code I wrote failed to execute as expected.Īdmittedly, my programming experience is limited to HTML and JavaScript. Like LearnStreet, teachers can sign up to be "coaches" for their students and manage their students' progress. You can also browse the programs written by other students. A space is provided for creating your own programs, which you can save in your profile and share with the world. It's easy to navigate the Khan Academy lessons and jump between them and the site's other features. After the coding technique is demonstrated in a video, you're challenged to write code that executes the technique. When your code isn't quite right, the tutorial provides hints to help you spot and correct the problem. Each video lesson animates the coding technique in a window on the left and shows the result of the code running in a window on the right.Īfter you watch the coding in action, you're challenged to write code that duplicates the operation. The courses are divided into about a dozen categories, each of which has from three to 12 separate lessons. Rather than focus on a particular programming language, the Khan Academy's programming module uses JavaScript to illustrate concepts that apply to coding in general while also teaching some practical JavaScript skills. The Khan Academy is famous for its ground-breaking video tutorials covering nearly every subject a student is likely to encounter. Khan Academy lays a solid programming foundation

LearnStreet also offers free courseware for teachers who want to instruct their students in coding. The projects can be sorted by level (beginner, intermediate, advanced) and by category (tools, games, and algorithms). Once you finish the site's programming courses, you can turn your attention to the dozens of coding projects for JavaScript, Python, and Ruby. It took me about two hours to work my way through the first five lessons in LearnStreet's 12-lesson Ruby for Beginners. LearnStreet's Ruby tutorial prompts you with hints and answers when you make a mistake in its coding exercises. The instructions are listed on the left side of the screen. Under the code is the run environment that demonstrates the code you write.

The first thing you notice when you start the lessons on LearnStreet is the prominent code-entry screen on the right side of the window.

Each of its dozens of lessons includes plenty of "Try it yourself" options for practicing the technique the step covers. The simplest of the coding tutorials I tried was 's JavaScript tutorial, which you can complete without having to register (unlike the other three services). If you've done a little coding in the past, you'll likely have better luck than I did with Codecademy's write-it-yourself approach. I made it through 24 percent of the Codecademy's Ruby tutorial before I hit a lesson that stopped me in my tracks: in the loops section, of course. However, the complete program could easily take weeks to complete. The video lessons in Khan Academy's Programming curriculum keep you engaged in the subject and are perfect for folks starting at square one. The lessons prompt you to write and run the code for each step, and when you make a mistake - which is key to learning how to program - the correction hints are clear. (Note that all but requires that you register to use the service by providing an e-mail address and password.)Īll four of the coding tutorials I tested have their positive attributes (ahem), but my favorite is LearnStreet's Ruby for Beginners, which was just my speed. Whether you're a programming newbie or an old hand looking to learn a new skill or two, these four free services have you covered. Learning how to code has never been easier.

In the not-too-distant future, writing code may be as commonplace as typing and other forms of text-keying are today. The number of people who spend their workday coding continues to soar. Now we're all tapping away at keyboards and screens from morning until night. Not so long ago, typing was for secretaries, journalists, and would-be authors.
