Several people have asked me about using propensity score matching with complex surveys, and whether/how weights, PSUs and strata should be taken into account. This paper explains how to handle these issues.
Narcissists in education: an empirical analysis of tweets
This is excellent:
Should we be using multiple imputation? Perhaps not
Several years ago I took a missing data workshop from Paul Allison, where he extolled the virtues of MI. He has apparently changed his stance on this, and his intellect is such that we should be paying close attention to what he is saying:
Measuring college student learning in the UNC system
The General Education Council of the UNC General Administration asked me to give a presentation on issues around measuring student learning in higher education. Slides are here.
The state has adopted an ambitious strategic plan; one of their stated strategies is “Become a national leader in the assessment of student learning gains” (p. 44).

I recently started a quant methods working group at the College of Education here, and gave a presentation on propensity score matching for people who had heard about it and wanted to know more.

WEIGHTING: WHY, WHEN, AND HOW?
Making my code public
My New Year’s resolution for 2014 is to publicly post all of my Stata code for my projects. Why? This will force me to be more careful with my code, even though I am already somewhat anal when it comes to my code.
Replication of research: more bad news
The amount of evidence demonstrating that most published empirical studies are crap seems to be increasing. See, for example, this article from the Economist.
This is a great piece on how a student debunked a psychology study by some big guns in his field. Title: Nick Brown Smelled Bull. Funny, I smell that a lot when I read the higher ed journals.
