Want to learn about a topic? Try writing about it

Every now and then, I’ll peruse the forums on SSC.  In addition to people answering questions about SQL Server, there also tends to be some banter, which is probably not unusual in many forums of this nature.  One of the comments I’ve seen time and again is something like, “I learn more about subjects by answering people’s comments on these forums.”

There is more truth to this statement than people realize.  In my experience in writing about technology, I often find that I end up learning about the technology about which I’m writing — sometimes to the point of becoming a subject matter expert.

Several years ago, I taught part-time at a local business school (roughly equivalent to community college level).  I taught primarily general mathematics and a few computer classes.  I was once asked to fill in for another instructor who taught statistics.  My problem: I didn’t know much about statistics.  So, I read up on it (along with the syllabus that I would be teaching that day).  I wanted to at least be able to sound like I knew what I was talking about.  As it turned out, by teaching that class, I actually learned something about it.  The students were not the only ones who got an education that day.

The other day, I began writing a draft article regarding a subject about which I’d like to learn more: BI (edit: the now-finished article can be seen here.).  I’ve dabbled in BI a little bit; I worked a previous job where I was asked to perform some data analysis (which is how I learned about cubes and pivot tables), and I took a course in decision-support systems in grad school.  I’m seeing more SQL Saturday presentations about BI; indeed, there are even SQL Saturday conferences dedicated to BI topics (usually indicated by the words “BI Edition”).  It is a topic about which I do have some interest, and it’s something about which I’d like to learn more.

My friend, Paresh Motiwala, who was one of the organizers for SQL Saturday Boston BI Edition a while back, encouraged me to apply to speak at the event.  I said to him at the time, “the only thing I know about BI is how to spell it!”  (His response: “Hey, you know how to spell SQL!”)  On hindsight, I probably should have applied; it turns out that even BI Edition conferences accept professional development topics, under which nearly all of my presentations (so far) are categorized.

So if I claim to know so little about BI, why did I decide to start writing about it?  Well, I’m trying to learn about it, and I’d like to pass along what I learn.  But, I want to place a greater emphasis on the first part of that statement: I’m trying to learn about it.  Writing about it makes me learn something about it a little more in-depth.  And by doing so, I discover that I have a better grasp of the topic.

Hopefully, relatively soon, you’ll see an article from me about BI.  Hopefully, I’ll have learned enough writing about it that you’ll be able to learn something from me.  And hopefully, I’ll have demonstrated that I’m learning something new, and improving myself in the process.

If you want to learn something new, try teaching it or writing about it.  You’ll be surprised how much you, yourself, learn in the process.
