Let us imagine that you are an adult learner who wants to keep learning, but are not looking for academic qualifications. What do you do?
If you go with most agencies, they will likely offer you courses or modules. These might lead up to something or they might be self-contained. But they are still not designed with you in mind because there are desired outcomes, learning objectives, and curricula determined by someone else.
What are you looking for does not quite exist in the schooling and vendor realms. Instead what you need is designed with two main principles: Just-in-time (JIT) and just-for-me (JFE).
What you need is experiences. An extended vacation might do the trick if you travel light and learn on the run. If you stay in a place where the residents do not speak your native tongue, then you might pick up a new language.
But that is not the bi- or multilingualism I am thinking most people need to experience.
I see the wisdom of thought leaders who suggest that kids be comfortable in one or more programming language. That is something a school or vendor can help provide. A very motivated individual can also learn this on his or her own thanks to the multitude of books and online resources on programming.
Without this language, most individuals can problem-seek. But armed with the ability to program well, individuals have one more tool with which to problem-solve.
The older adult learner is unlikely to want or need programming language skills. So what experiences might they invest in?
I suggest being fluent in the daily language of operating systems. The dominant ones are Windows and Mac OS on larger screens, and Android and iOS on smaller screens. We might throw Chrome OS on both screens for good measure.
Being conversant in more than one operating system language can help older learners problem-seek and problem-solve on any major computing platform.
If you need to book that vacation, can you do the research, take notes, seek advice, book a cheap flight, and get the ideal Airbnb place on desktop and mobile devices? Do you know the merits or demerits on each platform?
Now imagine having to offer your services or wishing to stay relevant to clients who are likely on different platforms. You might create an online presence on one platform, but does it look the way you want it to on another? You can only know for sure if you are comfortable, or better still, fluent in all major OS languages.
This is why I have no qualms about investing in various devices with different operating systems. They create learning opportunities just-for-me and just-in-time.
When articles run on techie sites or blogs about devices running a particular operating system, there will invariably be a comment war where one side slimes the other. This is as pointless as arguing whether one language is better than another.
The more you learn, the more you realize how they are more the same than different. Then the fights seem small-minded and petty.
