Quickly Transitioning to Teaching Online Due to COVID-19

[Andy Resnick]

There is no unified approach, everyone is left on their own.

That's a problem for a variety of reasons. Please try to encourage coordinated responses and actions by the Department (and ask the Chair to coordinate with other Departments) to prevent future problems and reduce student anxiety.

Has anyone altered or considered altering their course grading rubrics due to these circumstances?

My prof in my differential equations class changed it so quizzes and tests that occurred before the cancellation of classes carry heavier weight. Material tested during the online portion of the course will not count as much towards the final grade. I'm not so sure she can do this without consent of the students, but I could be mistaken.

I don't think it has anything to do with the "consent of the students", but rather with the policy of the school and the department. In my Syllabus, I reserve the right to change the content if the situation calls for it. And the current situation certainly fits the bill.

In my Astro course, the students now have to do a lot more work in filling out their weekly worksheet. So for the grades to be commensurate with the new amount of effort, I've increases the percentage of the worksheet grades from 10% to 20%. I've also dropped one of the midterm exams because we have essentially lost almost 2 weeks of class time, and could not cover one whole chapter, while I had to consolidate one topic into another during the same week.

All of these changes are allowed within the boundaries stated by the Syllabus that I handed out at the beginning of class, and my school allows me to make those changes.

In the institutions I've taught in, changing the weighting of early grades after the fact might be justification for a grade appeal if the course grade computed from the new weighting was lower than that computed from the original weighting. However, you have no idea right now how that appeal would go at your institution. Every student appeal that every occurred in my courses was denied.

My advice? Work hard to achieve your grade goal with the current weighting system. That's a guarantee. A grade appeal, while possible, is a dicey deal. Administrators have to hear grade appeals. I doubt many would listen to your complaining now with all they have going on.

 

[Mondayman]

At my last university instructors required explicit consent of the students to make a drastic change to the grading scheme posted in the course outline. I never heard of an instructor making changes that weren't beneficial to the students, so I don't believe it was ever an issue.

I doubt many would listen to your complaining now with all they have going on.

No one's complaining as far as I know. I'm certainly not, I do my work. I was mostly curious as to what other instructors did in regards to the current situation. In my case, the final has been lowered to the point of it being worth less than homework or the first midterm. It seems like too easy a pass to me.

At my last university instructors required explicit consent of the students to make a drastic change to the grading scheme posted in the course outline.

A motion could be passed by the Senate of your university that would give faculty the ability to change grading schemes.

Pasco has made some resources available to help with online lab activities.

Public Libraries in my county are shut for the immediate future by order of the state governor. No public Internet access. No paper book exchanges or other physical media. All social instruction on hiatus. Local university opened today for online classes after spring break. I am informed that university library remains closed. No physical study groups.

Suggestion for hands-on labs from Radar Science courses I helped design and teach:

We rebuilt working simulators with the latest gadgets as electronic laboratories with calibrated test equipment, probes, meters, spectrum anylyzers, O-scopes, etc. available in the radar vans. While I lectured on theory and particular applications in classroom setting following actual use of the systems, my fellow instructor introduced typical error states in the radar systems. Advanced students then divided into teams of two and troubleshot the problems*. We then debriefed and evaluated results.

We thought this method -- lecture, hands-on experiments, advanced theory, actual trouble-shooting, group evaluation -- on a daily basis best taught theory, operations and troubleshooting as experienced in the field during experiments (real-time missions to instruct visiting pilots).

The idea I am attempting to convey is to interleave lecture and labs in order to maximize resource allocation, particularly costly equipment, in small group settings with optimum skill retention. Similar methods have been adapted to remotely teach surgical students and EMT technicians optimizing valuable lecturer times -- which can be recorded but kept fresh -- and sparse expensive equipment.

*under quarantine conditions equipment can be cleansed between uses, lab partners can communicate via communication devices while instructors and assistants monitor lab activities via video links. Lectures, evaluations and discussions are all conducted electronically as previous posts describe. The only physical presence requires students to interact with equipment installations. Training partners can be gloved, masked as appropriate with all required safety equipment and/or be connected electronically.

Not exactly a teaching issue, but we are now trying to maintain a skeleton crew of faculty and staff to maintain critical research activities: NMR refrigeration, LN2 dewars, animal care, etc. It's a battle, and not a fun one.

I am streaming the lectures at the scheduled hours via Zoom. Once they are over I make slight edits and post them online for students that have missed the lecture or want to go back to look again. I use a setup where I can use my iPad Pro as a replacement for the blackboard. I would say it works pretty well. Today I stopped connecting the iPad to the laptop and started to instead log into the Zoom session directly from the iPad and share the screen in addition to using the laptop to stream the audio/video.

Since I don't have a touch-screen computer, I use my iPad as a whiteboard if I have to write something quickly. I have an app on the iPad called AirSketch where I can write on the iPad, and whatever I wrote is mirrored on my computer screen. So if I need to show the students some quick derivation of something during a Zoom session, I find that to be the most convenient way to do it.

Because my computer can use the iPad as a second display, and Zoom can share the screen of the iPad, I've been trying different permutations to see which works best. Next class, I'll run Keynote on my Mac and use the iPad as a remote. This way, I can see the presenter's notes, and I can use the Apple Pencil to control the laser pointer or to write on the slides. If I need to work out a longer problem, I'll share the iPad's screen and work the problem out in Noteshelf or GoodNotes.

Hey all,

What would be a good simulation software for electric circuit labs for intro physics? Software must be free to download. I was pointed to Pspice, but they don't have the light version any more. There is a student version, but they ask students to upload a copy of their student IDs, which might be a big no no from my school. So, what options are out there? I need ways to do the following labs: Investigating Ohm's and Kirchhoff's Laws, Parallel/Series circuits, voltage dividers, and behavior of RC, LC, and LRC circuits.

So, what options are out there?

I did a Google search on +free SPICE simulator and got a number of hits:

We're starting to get reports of 'Zoom-bombing': when a malicious individual finds an open Zoom meeting link and enters the meeting to disrupt it verbally or by sharing inappropriate material.

We're starting to get reports of 'Zoom-bombing': when a malicious individual finds an open Zoom meeting link and enters the meeting to disrupt it verbally or by sharing inappropriate material.

We have been warned about that happening, so I've been insisting that students log into their school's Zoom account before joining the session. I may have to hold them in the virtual "waiting room" before pulling them in.
