Teaching Physics Online – One Year Retrospective

There’s been a bit of a lack of content here. Cavic has moved to the teaching Physics online world and it’s been a ride. I started teaching remote, like the rest of the world, during COVID. I loved it so much that I decided to move my career in that direction.

So here we are, a year later. Moving to full-time online teaching is definitely a transition, especially with a course like Physics. Here are five things I’ve learned teaching virtual Physics.

1. Know your course

I know it’s impossible to do everything yourself. Don’t reinvent the wheel and all that. However, it’s important to know the course and content you are teaching. As obvious as that may seem, a lot of schools and districts buy premade programs that teachers had no input in. If this is the case, learn the content and the way it is presented to your students. Write review guides and/or make videos for students to clarify information that needs it and teach things “your way.”

Whether you have the luxury of going through the entire course before teaching it or you simply go through the next unit the week before you start it, make sure you go through all information students receive and experience your course as a student. I have always used resources with this principle: Never assign something to students that you have not completed yourself.

Never assign something to students that you have not completed yourself.

2. Quality resources are essential

In the classroom, you, the teacher, are always there to answer questions and see when students need help. In online spaces, you lose that sense of when students need you. Enter quality, teacher-made resources. Start with identifying areas in your course that students typically have trouble with or have common misconceptions about. Create a help site for students with videos, lab template documents, guided notes, etc. to help them when you aren’t available.

You can make a simple, easy to create and use help site using Google Sites

If you need help finding quality resources to supplement your course, here are some of my favorite resources for Physics and Astronomy.

Of course, you don’t have to do all of this upfront, but it’s an excellent goal to build towards as you make your way through your first year of online teaching. Try to consistently add to your library of resources as you have time.

3. You can and should still do labs when teaching Physics online!

Hands-on, inquiry-based learning is SO important in Physics. Physics really is a course of doing. Labs are arguably even more important in a virtual setting – students have trouble connecting and engaging with just words and problems.

There are a ton of resources and simulations out there to help foster that hands-on experience in a virtual setting. Focus on adding and/or creating labs that have students actually manipulate variables, mimicking a real lab setting. PhET has amazing simulations for almost every topic in Physics. I also love oPhysics – they aren’t as flashy, but they have a ton of simulations to work with.

Here’s an example of a great GeoGebra-based simulation from oPhysics.

4. Make yourself approachable and available

I know every school and district has different policies in place about how you are allowed to communicate with students. Work within your restraints and make yourself available to your students in as many ways as possible.

Google Voice has truly been game-changing – I love being able to text students from a work-only number. Students tend to see and respond to texts faster than any other method of communication. They also are more open to reaching out to me than through video channels – the camera-shyness is real!

Be open and available, but within reason. Make a schedule for yourself and students to set expectations and boundaries. Here is an example day schedule for how I break up my day.

You can also offer live lessons, Zoom office hours, and hours in which you will quickly respond to emails. Make yourself a schedule to not overwork yourself, but have times when students know they can get a quick response from you.

5. Be understanding and flexible

Virtual learning can be a challenge. Some students thrive in a self-paced environment. Some students need structure and due dates. Be prepared to accommodate different levels of structure for your students.

The same goes for due dates and timelines. Depending on your online Physics situation, you may have students juggling a lot of classes in-person and online. Set realistic expectations and be flexible if things change! Communication really is key for successfully teaching Physics online.

There are my top five things I’ve learned the last year teaching Physics online. If you’ve made the transition to online or blended learning, I hope these tips have been useful in structuring your course and resources for your students. Happy teaching!

The Experimental Design FRQ: Rethinking Labs

I previously discussed my tips of the AP Physics 1 and 2 FRQS, but I realize I didn’t really touch on the experimental design FRQ. I will write out some tips for that beast, but I want to discuss how I prepare my students for this throughout the school year.

The experimental design FRQ is probably the most daunting to students and teachers. The first time I had my students do one in class, it was truly abysmal. How can teachers prepare students for the experimental design FRQ?

I think the number one answer to this question is by flipping the way we do labs. So many of us are used to traditional labs with instructions that tell the students exactly what to do.

Sample student response from the 2017 experimental design FRQ
Check out the amount of writing required on these FRQs! Here is the full sample from 2017.

Labs are the ultimate exercise in inquiry for science classes. Many teachers struggle with having the time for inquiry, but inquiry labs don’t have to take any longer than traditional “cookbook” labs. Let’s look at the four levels on inquiry, with an example lab in AP Physics 1. If my explanations aren’t enough, here is some more detail on the four levels of inquiry from Inquiry in Education.

Level 1: Limited

Limited tends to require the least amount of critical thinking. Students prove something using a prescribed procedure. For instance, students prove the acceleration of gravity by dropped a picket fence through a photogate for 10 trials, average them, and find a percent error. Bad? No. Does this prepare students for the experimental design FRQ? Also no.

Level 2: Structured

Most of the labs I did in high school and college were structured. This is where our more traditional labs lie. The teacher provides the question and the procedure, and the students work through it. Higher order thinking may come in during the analysis portion of a structured inquiry lab, but the actual lab is fairly straight forward.

An example of this would be investigating the relationship between force, mass, and acceleration. Students are instructed to vary the force pushing a cart and a the mass of the cart, and derive Newton’s 2nd Law.

Level 3: Guided

Guided inquiry is really the sweet spot for preparing students for the experimental design FRQ. In guided inquiry, the teacher provides the problem and the students must come up with the procedure, data, and analysis to answer the problem.

I bought these poppers from Oriental Trading for a guided inquiry lab on energy!

This format most closely matches the types of questions students see on the experimental design FRQ. Through doing guided inquiry labs, students become used to figuring out their own procedure. Of course, every lab can’t be guided inquiry. However, this is a great tool to use during each unit. I will share some of my own examples below.

Level 4: Open

Open inquiry takes the student generated process a bit further. Students come up with the question, in addition to the procedure. I think that open inquiry is a great end-of-year review tool, but I don’t really use open inquiry for labs during the school year.

5 guided inquiry labs you can do next school year to prepare for the experimental design FRQ

So, now that you know a little bit about the types of labs, let’s look at how you can use structured inquiry labs to prepare students for the experimental design FRQ.

  • Projectile motion
    • Where will the marble land? A marble is shot out of a marble launcher, and students must place a cup so that the marble lands in it on the first try. Students can use whatever tools needed to figure this out, but they can not launch the marble during the procedure phase. I combat “cheating” by launching the marble early by not giving them the angle the final trial will take place at until the end.
  • Coefficient of friction
    • Does the coefficient of friction depend on the mass of an object? Students are given force sensors, various masses, rulers, and are able to gather additional materials if necessary.
  • Energy conversions
    • What is the spring constant of a popper toy? Students can use any lab materials available to them to determine the spring constant. The stipulation is that they must do it using energy, not Hooke’s Law. Most students choose to use video analysis using their phone, which I why I like not giving them set materials.
  • Rotational kinetic energy
    • An object rolls down a ramp. Does its percentage of translational versus rotational kinetic energy depend on its shape? Students are given a ramp, meter stick, and various objects (hoop, sphere, cylinder). They determine how much of each object’s initial gravitational potential energy is rotational kinetic energy at the end of the ramp.
  • Pendulum
    • What factor determine the period of a pendulum? Students must test at least four factors and derive an equation for the period of a pendulum.

Final thoughts

Of course, the goal of all labs is not just to prepare students for one FRQ on the National Exam. However, giving students genuine experiences in experimental design will prepare them and push their critical thinking skills. A good lab course uses a mix of different types and styles of labs, with guided inquiry being one part.

Also, don’t think you have to reinvent the wheel to push your students. How can you kick labs you already do up a level?

EdTech Tools for Physics: Top 5 Free Tools

Educational technology, or EdTech, is changing the way classrooms are structured. Classes are becoming more student-centered and collaborative through the use of technology, but many tools are too costly to implement. Here are five free EdTech tools for Physics that I have used with success. These tools are not necessarily just for Physics, but have worked well for my Physics classroom!

1. Nearpod

I like to think about how technology can enrich an experience, rather than how it can replace something. It’s easy to add tech – it takes practice and reflection to make it enrich the curriculum. Nearpod is one of those tools that can truly enrich an otherwise lackluster lesson.

Nearpod is nearly limitless in its classroom possibilities. I discussed it a bit already in my 5 Ways to Make Instruction More Student Driven. It truly is the most powerful tool I use in the classroom. It can transform a lesson from static an uninspiring to whole class participation and collaboration.

Sample Draw It featuring student-drawn motion graphs in Nearpod
Here is a real sample of some student drawings using the Draw It feature. The teacher receives all the drawings and can share them out to the class. We spent several minutes in this class going through each drawing and discussing what type of motion it showed.

Some of my favorite features within Nearpod are:

  • Collaboration boards
  • Importing existing PowerPoints and adding activities easily
  • Integration with PhET
  • 3D models and virtual field trips
  • Adding a slideshow for structured browsing time
Sample Collaborate Tool in Nearpod - one of my favorite edtech tools for physics!
Possibly my favorite feature of Nearpod in action! These collaboration boards are a great way to have students ask questions, share thoughts, and gauge prior knowledge. I love giving students the opportunity to put things into their own words for each other.

2. PhET

I would bet that if you are reading this website about Physics, you are already familiar with PhET Interactive Simulations. It is one of the most popular and widely used EdTech tools for Physics. Thousands of science teachers use these simulations for virtual lab experiences.

Using the PhET spring simulation as a virtual lab
One of the guided inquiry labs I do using PhET is finding out the mystery mass for this oscillating spring.

One of the reasons I love PhET is the flexibility in the style of investigations you can do. Even if you currently use PhET, I challenge you to kick your activities to the next level by including guided inquiry opportunities. These simulations are perfect for inquiry you can’t physically do in the classroom.

If you are a teacher, PhET does have some teacher created lessons you can access and use. I find that many teachers don’t know about this feature! You sign up for an account using your school email address, and the tools are located under each simulation.

Resources available to teachers for every PhET simulation
Example of some of the teacher resources available. These were all created by other teachers. If you like PhET, maybe submit some of your own resources to share with others!

PhET is also slowly making its simulations HTML5. If you don’t use it because of compatibility issues, check if your favorites sims are updated!

3. Quizizz

I am a newer user of Quizizz, but this school year I began incorporating it frequently in my classroom.

I like Kahoot. Students love Kahoot. Kahoot just doesn’t work for me. I find that students like it TOO much, which can lead to chaos and students not really reading the questions carefully. I also find that it just doesn’t have the flexibility and customization tools I want.

Enter Quizizz. You can utilize Quizizz in many different ways. I tend to use it as a class warm up, or “bell work,” activity. I like the ability to turn off the question timer, add the memes for a good laugh, and assign it as in class or at home. You have the flexibility to make Quizizz as fast-paced or relaxed as you want. There are dozens of Quizizz made by other teachers, and it is super easy to add your own questions.

Quizizz also has really in depth item analysis tools, which I review with my students after each game.

Sample student data from Quizizz
One of the item analysis tools is this student performance matrix (I cut off the students’ names on the left). I like being able to see a snapshot of each question’s score, plus each student’s performance. My students struggled with these questions a lot, so we did some reinforcement after this!

4. Tes Teach

Tes Teach with Blendspace is a platform to make choice boards online. You can make the tiles a wide variety of activities, which makes giving students choices super user-friendly.

Example tic-tac-toe board using Tes Teach - another one of the best edtech tools for physics
Here is a board I made for AP Physics 1. Students had to make tic-tac-toe that went through the middle, ensuring each student completed the exit ticket.

These boards don’t always look super pretty, but they are an effective way to give student’s choices in their learning. It is important to strategically place activities so that all students are working at the same level of rigor. I wouldn’t want one student watching three videos while other does three higher level free response questions.

5. GoSoapBox

GoSoapBox is a new tool I am testing out. It is a diverse and promising tool. I really think this might be one of the most beneficial EdTech tools for Physics out there right now.

GoSoapBox has a plethora of features. The most intriguing one is a clicker-type interface that can act as a “back channel” for your class. While clickers aren’t anything new, they are expensive and not realistic for many schools. GoSoapBox works on practically any device and does so much more than the clickers I used in college.

Here is the teacher dashboard for a sample lesson I created. GoSoapBox calls their lessons “events.”

On the teacher dashboard, you can create quizzes, polls, and discussions for students to respond to using their device. The Social Q&A feature is my favorite, however. Students can write in questions during a lecture discussion, and other students can see those questions. Students can also “like” other questions to indicate they were thinking the same thing.

Some edtech tools for physics are available within GoSoapBox, such as this live confusion barometer to use during lecture style classes
This is what the students see on their device. There are currently no active quizzes or polls, but students can still ask questions and use the barometer.

The confusion barometer is another feature that could really benefit Physics classes. Sometimes I feel like I completely lose my class mid-discussion, and the confusion barometer can help me be aware of that. At any time, students can toggle the barometer to “I am confused” and the teacher will see how many students are lost.

There are hundreds of EdTech tools out there, and I discussed just five of them today. Do you know of any other EdTech tools for Physics classes? What are you doing to disrupt education in your classroom?

Kanban Boards for Teachers: Making business productivity work in the classroom

Time management is my biggest challenge as a teacher. I used to stay after school every single day for 2 hours or more, as well as grade and lesson plan at home. I burned out. Work consumed my life.

I have done everything I can to make myself never feel like that again. A huge part of this career is managing your time. I have a very strict after school policy, as well as a personal philosophy about taking work home.

But come the end of the quarter, I STILL end up with a million last minute things to do. Enter my latest idea.

Kanban Boards

Kanban is extremely popular in the business world right now, especially in software development. This method helps to visualize the steps of a process. Generally, the process is categorized into, “To Do,” “Doing,” and “Done” or something similar. This can be virtual or a physical board displayed in the workplace. Tasks are moved through the stages until they are completed. It provides evidence and visualization for productivity.

 Why Use Kanban Boards? Here is an overview of Kanban boards and software, LeanKit, that is geared towards business solutions.

Last year, I had the idea that Kanban boards can be used for teachers. I decided to do lesson planning on the virtual platform, Trello. Trello is one of the most versatile productivity tools I have ever used – I have boards for my website, lesson plans, cooking, and home to-dos. I love my lesson planning board, but I also like to hand write my lesson plans. I enjoy having physically to-do lists. Additionally, I wanted students to be able to contribute to-dos. Like I said in an earlier post, I want my classroom to be student-driven.

My personal lesson planning Trello board. I love being able to drag and drop the days if I need to adjust my lesson plans.

My New Board


I came up with a solution in a fit of frustration as my grading pile got larger and students kept reminding me of more to do. I made a physical Kanban board, put everything I needed to do on sticky notes, and invited students to add to it. Simple.

Excuse the messiness and unwashed board – I do not joke when I say I had the idea and implemented it within about 10 minutes.

It is messy – I will clean my board until it’s white again and redo the title cards. However, within minutes of setting this up, I felt my stress level decrease. If a student asked me to do something, I handed them a sticky note and put it in the to-do section. As I graded, I felt gratified as I got to move each sticky note to the “done” section.

What do you think? Are you as unorganized as I was? Do you think this method will help keep you on track? I hope the idea of Kanban boards for teachers will help get you thinking on how to organize your teaching!

Student-Driven Instruction: Rethinking Your Classroom

Student-driven instruction is one of the new buzz words, but it’s not just buzz. Education is moving towards a less structured, more student-paced, and student-led model. Changes like the emphasis on blended learning and the revised AP Physics exams are pushing these ideas forward. Going from a teacher-led class to a student-led one can be difficult, but here are some tips to help make your classroom all about the students.

1. Do away with neat rows

During my first two years teaching, I floated between classrooms and had to use whatever seating arrangement the other teacher used. When I got my own classroom my third year, the first thing I did was trade desks for tables. Even if you can not do this, putting desks in pods of four works the same.

This classroom structure is so important in creating the environment I want. In rows, it sets a tone that students may not talk and work together. In pods, every activity is collaborative. In every thing my students do, save unit tests, they are encouraged to have collaborative discussions.

I know this method seems difficult for some teachers. Another teacher came to my room and asked how I prevented them from talking. I don’t. I find that when they are in groups, they ask each other questions more often and tend to talk quietly, versus shouting across the room at their peers. This structure encourages quiet talking, which is good in a learning environment.

2. Notes through an interactive medium, such as Nearpod

I hate direct teaching. Everyone loses focus after twenty minutes or so. I limit the time I spend lecturing, but when I do I love using interactive media. Nearpod is one way to make lectures more student-led. Nearpod is extremely easy to use, especially if you already have PowerPoints you use for your course. You simply upload your PowerPoint and add activity slides to engage students. This is a great tool to revise your existing material into student-driven instruction.

These activity slides vary from quizzes, drawings, open-ended questions, virtual field trips, and more. Students also have notes on their own screen, which makes it easier for them to write down what they need. Nearpod can be used on laptops, tablets, computers, or cell phones. Even if you don’t have access to technology every day, using interactive notes is a great way to make lectures more engaging every once in a while. I sometimes have students use their own devices, and share with their partner if they don’t each have one.

3. Collaborative corrections

I like using this method with things like free-response questions or homework that I have handed back. I will grade the assignment with little feedback or corrections, except a few clues. Students work together to put the clues together and come to the correct answer. Even grading can be considered student-driven instruction with this method.

Some teachers call this homework circles, or simply corrections, but whatever you call it works. This method engages students in making corrections on their work and learning from their peers. It also makes grading easier – instead of giving them the answer, they have to work for it.

4. Less cookbook, more inquiry

I begin most units with an inquiry demonstration or lab. Then throughout the unit, we revisit the lab and try to come to new conclusions. It makes the learning process a puzzle that we slowly put together.

It’s hard sometimes to give control to the students. It’s hard to not give them answers. It frustrates them at first. However, these learning processes are important in making actual connections, and not just memorizing facts.

Inquiry learning can vary from questioning, research, labs, demonstrations, and more. I will be posting some ideas for Physics and Astronomy classes in the future – stay tuned! (Here is my post on using inquiry labs in AP Physics!)

5. Involve students in questioning

This is always difficult for students and teachers, but it is a deep learning exercise. One way I like to do this is having students write their own questions. Those questions are used in review games, and some may even appear on tests. Question creation can even be used as an introductory technique to just get their brains going.

A Webb's Depth of Knowledge chart to help include questioning strategies in student-driven instruction

I usually have students try to create questions from each of Webb’s Depth of Knowledge domains. Without structure, students tend to stay in domain 1. Charts like this help students create more rigorous questions.

Another example of question stems used for student-driven instruction

If students need even more guidance, especially in the beginning of the year, you can use question stems. These help guide students in what makes a question deeper.

For activities focused on getting the brain going, I like things like Q-matrices, Q-dice, and Q-chips. You can purchase these things from various educational companies, or make your own!

Engaging your students in the classroom is important to do every day. Student-driven instruction engages students and forms more meaningful educational experiences. I hope these ideas help foster a more student-driven culture in your classroom.
