Just finished the second week of the Boom Startup Ed Tech accelerator, which is GREAT. I am learning a lot and plan on working insane hours for the next few months to put it all into practice. We have had to answer a lot of legitimately hard questions about cash flow analysis, burn rate, user…
A few months ago, in between everything else in my life, I had been working on applications for accelerators and an executive summary for investors. While money is always a good thing, I was surprised by the unexpected benefits. The questions asked by investors are the same ones you should be asking yourself. If you…
I read this in a review of a study on teacher expectancy effects but it could really apply to so many other studies. If these results bear any relationship at all to reality, it is indeed a fortunate coincidence. Those of us who choose careers in research like to believe that it is all like…
In assessing whether our Fish Lake game really works to teach fractions, we collect a lot of data, including a pretest and a post-test. We also use a lot of types of items, including a couple of essay questions. Being reasonable people, we are interested in the extent to which the ratings on these items…
Having been in Rio the past two weeks where Internet access occurred in five-minute increments roughly 11 hours apart, I have a few blog posts saved up I was unable to upload. Expect a few more over the next few days. July 26,2015 I was in our office at the Water Garden exactly 1 day…
Sometimes, you can just eyeball it. Really, if something truly is an outlier, you ought to be able to spot it. Take this plot, for example. It should be pretty obvious that the vast majority of our sample for the Fish Lake game were students in grades, 4, 5 and 6. Those in the lower…
I’m really busy here in Brazil. Honest. You think I am sitting here like this: But really, it’s like this: Still, I have taken time away to explain to you how not to get your sorry ass fired, so listen up niños . I had the benefit of starting writing software at a large organization,…
Well, I don’t know about you, but I am anyway, and I’m guessing if you are reading this that you probably are, too. If you read the bottom half of the internet (a.k.a. the comments section), you’ll find that any mention of privilege sets some people off … I’m not privileged! My parents didn’t have…
It was recently noted on our company twitter account that I’m out of town so often that I’ve come to resemble the Travelocity gnome in more than stature. I’ve been traveling on business for nearly my entire career. Despite the proliferation of Google hangouts, Skype, Webex, Go-to-Meeting, FaceTime and God knows how many other technological…
Previously, I discussed PROC FREQ for checking the validity of your data. Now we are on to data analysis, but, as anyone who does analysis for more than about 23 minutes can tell you, cleaning your data and doing analysis is seldom a two-step process. In fact, it’s more like a loop of two steps,…
