To the current and future moderators: I think the criteria Liam brought up is an important one... to leave in! We should be exchanging ideas about pedagogy and...
I do not find posts such as Liam McDaid's useful. There are lots of places on the internet to express opinions, but that is not the purpose of astrolrner. I...
And some of us do not lecture. I find it totally ineffective for my students and don't use it. This is exactly why we should have the opportunity to share...

Can't help myself - must weigh in... 1) The moderators do a great job - and yes I have been censored in the past over language used, they were right but it...
Hello all! I first wrote you all a few months ago about my desire to write an AER publication. My topic will be Teaching Astro 101 Online and in Virtual...
Angela, Thank you for your correction to what I said about Astrolrner being Astro 101 centered. I do agree with what you said. Many of the techniques discussed...
I've recently become part of a K-14 professional development group known as the Galileo Group (the name is a simple coincidence; the focus is on general...
... For SecondLife, I would like to see a focus on the 3D aspects of teaching. Powerpoint presentations and streaming video is nice but using SecondLife as a...
Jim, I'd like to know 1). How to integrate a virtual experience (2nd life or even a space sim) into the curriculum. I mean what elements of the sim will be...
Danny, I've only had one experience but it was major. My graduate level "Atoms and Molecules" physics class was taught by Alan van Heuvelen (now at Rutgers),...
Hi Jim, I'm sure many of us on Astrolrner@CAE are very much looking forward to your insights into online teaching-we increasingly hear from our workshop ...

Hello all, The recent discussion regarding the focus of astrolrner raises a significant question for our community to consider. Astrolrner is an important...

Hi Y'All I'll be presenting some stuff at the AAS on using learner-centered techniques in upper division classes. And the technique I will present is also...
I'd like to see researchers use astrolrner because the rest of us are then exposed to their ideas as they develop. And they might gain from comments we make. ...
For anyone in the SoCal area, I am giving an invited talk on our national study on Astro 101 teaching and learning (featured in our Physics Today article) on...
I agree ith Steve. Knowing what research is going on and how it is being conducted allows us to modify projects we are working on and also lets us explain a...
Hi, all - Does anyone know whether the CCDs in store-bought digital cameras can detect cosmic rays? Once upon a lifetime ago, cosmic ray hits on the CCD chips...
Hmm...Cool idea. I don't know for sure but here's what my gut tells me. Yes you technically should be able to detect cosmic rays, or rather cosmic rays would...

Some Digital SLR cameras provide an option, 'B' for bulb, that allows taking long exposures, many minutes in fact on those DSLRs that have the 'B' function....
I agree with Dan that finding cosmic rays would be difficult to do with an inexpensive digital camera such as those on a cell phone because you don't have much...
Hello Everyone, At my university, we are at the period of the semester I personally find the most difficult. I call it the "post midterm doldrums." The...
 I enjoyed what Kendra did and realized my original post was written in terms of an actual photo, so I decided to do what Kendra did. My camera is a Canon XTi...
Interesting question re mid-term doldrums. I tend to notice it at about the 2/3 - 3/4 mark. It may have an analog in the infamous "dog days" (bonus obscure...
One way that you might distinguish a cosmic ray hit on a CCD from thermal noise is if you are lucky enough to catch a grazing hit. The result will be a streak...
I don't have a comment on the main issue, but I'd like to answer the bonus question. :-) It refers to Sirius, the "dog star," and its use as a marker of time...
Hi all, This year I took "just-in-time teaching" to a whole new level and I'd like to share my experience with you. I now assign homework due online BEFORE our...
Maybe you could import your image into IRAF or MaximDL or something similar, and do a surface plot. It would appear as a tight spike. Jim From: Chris Anderson...
I wanted to see if the number of hits that Roy and I have been seeing on our dark images was in the ballpark for the estimated number of cosmic ray hits per...
