Could the Interband Lag of Active Galactic Nucleus Vary Randomly?

The Astrophysical Journal
The interband lags among the optical broad-band continua of active galactic nuclei (AGNs) have been intensively explored over the past decade. However, the nature of the lags remains under debate.

Establishing The Empirical Relationship Between Non-Science Majoring Undergraduate Learners’ Spatial Thinking Skills And Their Conceptual Astronomy Knowledge

, 2013
The astronomy education community has tacitly assumed that learning astronomy is a conceptual domain resting upon spatial thinking skills. As a first step to formally identify an empirical relationship, undergraduate students in a non-major introductory ...

The State of Astronomy Education in the U.S.

, 1996
I would like to set the scene for the discussion that will follow in this book and bring up a few disturbing points which I believe any discussion about astronomy education will ultimately have to address.
