Cuesta College, San Luis Obispo, CA
Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.
The following questions were asked on reading textbook chapters and previewing presentations on Kirchhoff's laws.
Selected/edited responses are given below.
Describe something you found interesting from the assigned textbook reading or presentation preview, and explain why this was personally interesting for you.
"That astronomers use helioseismology to make observations based on Doppler, since no light emerges from within the sun. I think it's cool."
"Without a doubt learning about the Doppler Effect. We covered it in physics and Earth science but it's one of those things that I love covering over and over."
"I found the rainbow spectrum (continuous spectrum) to be interesting because its a " complete unbroken rainbow" how cool is that?"
"I thought it was really interesting when we covered the idea of the light spectrum when it comes to wavelengths. I like how I know understand how a neon light works because I found neon lights to be one of the coolest things, and still to this day, and so now that I can understand what makes the neon lights light up like that is something really cool to have under my belt. Plus it makes me sound smart."
"The description of sound moving toward us as 'squished' and having a higher pitch and sound moving away from us as 'stretched' and having a lower pitch--it helped me understand better which is higher pitched and which is lower."
"I really liked the atomic spectra section. I found it interesting how the spectrum of the Sun can reveal what it is made of."
"I would like to know more about Kirchhoff--he made some stellar laws. Light is awesomeeeee!"
"I'm sorry I honestly haven't gotten to the assignment yet I've had a crazy week."
Describe something you found confusing from the assigned textbook reading or presentation preview, and explain why this was personally confusing for you.
"On which spectra is which."
"I'm not sure if the Balrog is emitting or absorbing. I really don't know the intensity or lack thereof of the Balrog's light."
"Definitely gas atoms and how they play a role when talking about the spectra and telling the differences between spectra."
"How to tell what type of spectrum something will produce. I understand the differences between continuous, emission, and absorption but I am having a hard time actually telling the difference between them when it comes to the presentation slides."
"The Doppler effect confuses me the most out of this section. I'm also a little confused about the differences between emission lines and absorption lines, but I think the lecture will clear those concepts up."
I believe Pluto should be a planet. (Original responses.)

Briefly explain your answer to the previous question (whether Pluto should be a planet).
"We went over it in class that it is not a planet."
"Pluto does not fit humankind's current definition for a planet, which I still stand by."
"It's too tiny; doesn't meet the criteria to be a planet."
"I'm a traditionalist... It's the principle of it... Keep it a planet."
"Just as explained in the in-class activity, there are a lot of examples of objects that could qualify as planets if they didn't have objects around them. Pluto has to follow the rules regardless of human history."
"When we did the classification chart in class where we went thru the rules of what consists of a planet Pluto was classified as a dwarf planet so it wasn't in with the rest of the major planets."
"I don't think Pluto should be a planet because it is significantly smaller than all the other planets and it is closer to size to the dwarf planets. 3/12/2018 9:44 PM Categorize as... – View respondent's "
"Based on the criteria we went over a few weeks ago, I still don't think Pluto should be a planet because it doesn't not contain all of the required criteria that other planets do. It is a dwarf planet."
"It was once a planet, so it should always be a planet."
"Pluto was considered a planet before and it is still in our solar system so I believe it should still be a planet."
"I feel like it should be, but after learning how other planets have nothing else in its orbit makes me not think it should be."
"After the in-class discussion I have determined that is it not considered a planet, but because I've always be so pro-Pluto I had to put neutral."
"I can't decide because according to the planet flow chart it shouldn't be a planet, but i feel in my gut it should be a planet."
"Pluto is smaller than Earth's moon, and we don't classify the moon as a planet, so why would classify Pluto?"
"It doesn't meet all of the requirements according to the IAU."
"I think that Pluto is classified as a dwarf planet, and it makes sense as to why, I just feel bad for Pluto still."
"It doesn't meet the current requirements to be considered a planet. Although, I'm still a little sad because it kind of ruins 'Sailor Pluto' from Sailor Moon for me now, but whatever."
"It's still part of the Kuiper Belt...just a frozen chunk flying around...why are we still talking about this? Did I miss something?"
Match the spectrum type with their appearance.
(Only correct responses shown.)
Rainbow containing all colors: continuous [89%]
Rainbow with thin black lines: absorption [67%]
Colored lines on a black background: emission [89%]
Given off by hot, dense object: continuous [72%]
Given off by hot, diffuse gas atoms: emission [61%]
Passing through cool, diffuse gas atoms: [61%]

Ask the instructor an anonymous question, or make a comment. Selected questions/comments may be discussed in class.
"The Balrog was the coolest thing for my cousins and me growing up. We were/are really into the LOTR universe still."
"This section was a little difficult for me, can we go over this some more in class?"
"Can we go over the three different spectra in more detail?"
"I'm a little confused by the spectrum questions on this assignment, but I see we will go over them as slides which is a relief."
"When will we be able to see our total grade with the online assignments included? (Course point totals have already been posted online, we'll go over this in today's class.)
"Favorite movie that deals with astronomy?" (I don't think I have a favorite "entertainment" movie in terms of astronomy, but we'll watch one of my favorite astronomy documentaries this week in class.)
