I suddenly have to move my lab course online! What should I do?
In the wake of COVID-19, many faculty are being asked to quickly shift their lab classes online. (For general ideas about moving courses online, please see our other Expert Recommendation.) There hasn't been much research on making this type of sudden transition. We are sharing with you ideas and resources that align with research-based pedagogical principles, research-validated resources for teaching labs online, and ideas that colleagues are trying as they make this transition. This recommendation is being regularly updated during the outbreak, so if you have ideas and experiences to share, please let us know in the Comments section, or by emailing email@example.com.
Overall guiding ideas
- Please start with the overall guiding ideas in our other Expert Recommendation, which are applicable to all courses including labs.
- You can adapt labs you've already written, or look for lab curricula others have written that may work for your learning goals. You may likely have to adapt your learning goals and course expectations for this new situation.
- Be especially aware of equity issues as you move your lab course online. Some of your students may not have access to a smartphone or computer or reliable internet. Some of your students may not have access to household materials that you may expect to be common. Some of your students may be in environments difficult for conducting experiments (e.g., with children). Coming up with flexible options and approaching your students' varying situations with understanding is especially important.
How different lab components can move online
Labs typically comprise a variety of components. The lab components listed directly below can be moved online in a similar way to moving a lecture-based course online (or might even be online already in your course). For these components, see our other Expert Recommendation with advice for moving your lecture course online, especially the section on moving group work online.
- Pre-lab and/or post-lab assignment
- Come up with questions to investigate
- Interpret data / create models / reflect on results
- Write a lab report
- Create a class presentation
- Give each other feedback on any of the above
By contrast, the lab components listed below are those that need to be majorly re-thought as you move your course online. In this Expert Recommendation, we offer ideas for moving each of these components online.
- Observe a phenomenon
- Design an experiment including troubleshooting
- Collect data (ie make measurements)
- Analyze and visualize data
- Develop technical and practical laboratory skills
Ideas for observing a phenomenon and collecting data
- Students can observe astronomy and physics phenomena in their daily lives, without actually having to perform an experiment (e.g., rainbows in a glass of water, time and location of sunset)
- Students can use online simulations of physical phenomena. Many simulations allow you to adjust parameters and record data. There is research showing that students can actually learn more from a virtual lab than a physical lab (Finkelstein et al., 2005). See list of simulations below.
- Students can do an experiment with simple materials at home. Be aware that even materials you expect to be common may not be available to all of your students. Give options and be flexible. (And don't use dangerous materials!) See list of at-home experiments below.
- Doing experiments at home may help your students more clearly make connections between ideas they learn in class and their everyday lives. At the same time, they may feel less "sophisticated" to students than labs using fancy equipment, so you may want to explicitly highlight the authentic scientific practices students are engaging in.
- If you want students to make measurements, think about what kinds of measuring tools they might have available. E.g., a ruler, a protractor
- If students have a smartphone, they can use it to collect certain kinds of data. See resources below. Be aware that some of your students may not have access to a smartphone, or their phone may be too old for certain software.
- Students can video their own experiment to share with you and their classmates.
- You can consider putting together a box of equipment for your students to pick up and/or to mail to them. There are also companies that sell kits of equipment for doing labs at home, but we are not including resources that require additional cost to students or instructors.
- Students can do a combination of experimenting with simple materials to get the basic idea, blended with more detailed work using a simulation.
- Students can watch a video of an experiment. This can be a video you create or created by someone else. See list of videos in our other Expert Recommendation. Students can also make a measurement from an image (e.g., take a photo of an oscilloscope screen).
- In some cases, students can analyze the video to collect data on the experiment.
- See also ideas below for designing an experiment.
- You can give students a dataset to analyze, or help them to find a dataset in the literature. See list of resources for datasets below.
Ideas for designing an experiment and developing practical laboratory skills
- Students can work together (or alone) to write a proposal for an experiment.
- Students can read about or watch a video of an experiment and critique the design.
- Students can read about or watch a video of part of an experiment and write about what they would do next and why.
- You can have students vote on the next step, either by writing their ideas, or among a multiple-choice list. Then the instructor can video themselves doing that next step (to post asynchronously, or do it in real time on Zoom).
- Or you can create videos of multiple paths through an experiment (e.g., one path setting the dial to X value and another path setting the dial to Y value); then students watch the video corresponding to the step they choose (like choose-your-own-adventure).
- To develop troubleshooting skills:
- In an experiment they designed or read about: Students can discuss (in writing or synchronous Zoom discussion) what they think could potentially go wrong and what they would try in order to identify and fix potential problems.
- Students can watch a video of an unsuccessful experiment and discuss what they would do to identify and fix the problem.
- Helping students to develop practical laboratory skills without equipment will be difficult. But you may be able to create a video about particular techniques and ask students to write about the skills they see being used, questions they have, lab contexts where they think those skills would be used, etc.
Ideas for analyzing and visualizing data
- If students were previously doing this work on lab computers, try to get them access to the same or similar software for their own devices, and help them install and test it. Recognize that students' devices may be older and slower than lab computers, and that some students may not have access to devices at all.
- Help students collaborate while analyzing and visualizing data
- For analysis in spreadsheets: Google sheets, or emailing each other Excel files can work.
- Online Jupyter Notebooks - Platform for collaboratively working on Jupyter notebooks. There is a free version.
- Share files on Google Drive, Dropbox, or Github.
- Students can also share their screens in a Zoom breakout room
