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.

High School Astronomy: 5 Free Resources for Teachers

When I first began developing the curriculum for my high school Astronomy course, I realized that there are very few resources out there. Many things I found on the Internet were geared towards elementary. Anything more in depth was geared towards college. Through some searching and adapting, I found a few indispensable things for my classroom.

1. MinutePhysics

Oh, how I love MinutePhysics. Simple, engaging, and brief. These short videos often work as lead-ins to more in depth discussions in my classroom.  Some of my favorites to show in class are:

Why is the Solar System Flat? I show this one when we learn about solar nebular theory and the structure of the solar system. This comes after we do a lab to simulate the formation of planets from an accretion disk. Watch below to see what you think!

His very first video was What is Gravity?, which is a classic even if it isn’t as polished as later videos. Why is it Dark at Night? is a great video to use during a Cosmology unit.

There are hundreds of videos to chose from, and they are all excellently done.

2. APOD

I wrote an entire post about using APOD in the classroom, but it’s simply too good to leave off this list. Read that to see more detailed on how I use this resources in the classroom.

APOD is a great resource for high school Astronomy classes!

The main reason I love APOD is that my students learn something new every single day from it – even on test days or whatever other distraction the school has planned. The Astronomy Picture of the Day is often related to current events, which is great to show students how Astronomy is relevant right now.

You can also search through the archive of pictures to find the perfect image to illustrate whatever you are trying to teach. They have an archive that goes back to 1995.

3. Twitter

I love including current events in my class. APOD is one way I do that, another is Twitter. Usually at the beginning of the year, I will find news articles and tweets to share with students. After the first quarter, I put this responsibility on students. While all regular news outlets have accounts, I like to find Astronomy specific accounts.

NASA runs several accounts to share information. I recommend NASA Astronauts, International Space Station, and NASA History Office. There are many more official accounts, from each individual space center to astronauts’ personal accounts.

There are also great accounts by individuals. Canadian astronaut Chris Hadfield runs a wonderfully curated account, with posts ranging from news stories to things about his everyday experiences. Chris tends to be a class favorite. Emily Lakdawalla, senior editors at the Planetary Society, also shares a wealth of great information and insight.

I tend to assign students a day, and on that day they share something they found on Twitter. I have also tried having students create an account and share, reply, and generally engage with real science on Twitter. Both are excellent ways to bring real experiences into the classroom.

4. McDonald Observatory Outreach

For more traditional resources, McDonald Observatory out of The University of Texas at Austin runs an excellent site. They have lesson plans, labs, course outlines, activities, etc. This was pretty instrumental in helping me get started developing my course.

I used the Scale Solar System activity in the first week of school to give an introduction to the course. I like the Observing the Moon activity as an introduction to observational astronomy also at the beginning of the school year. This activity on Kepler’s Laws is also one that I still use.

Many of the resources here are excellent and can be adapted to fit your course and style.

5. VCPS Curriculum Map

Last, and probably the most important, is this Volusia County curriculum map. My school district does not have any set curriculum or guide for Astronomy. This made planning a bit difficult in the beginning. I organized the order and structure of my course based on this map. The state standards are also helpful to demonstrate that your course meets state guidelines. Even if you are not in Florida, this map is immensely helpful!

I hope you find these resources useful, as they were all instrumental in setting up my course.

5 Tips for New AP Physics Teachers

So you just found out you are teaching AP Physics for the first time? Or maybe you are a veteran teacher that needs some new resources? We have all been there. Beginning to teach a new subject can be difficult, especially if it is an AP course. Here are my tips for new AP Physics teachers.

What to do before the school year begins

1. Attend an AP Summer Institute

I attended the APSI at the University of South Florida the summer before I began teaching AP, and it was the single most valuable thing I did to prepare. The presenter gave us a wealth of resources, performed sample labs, and really delved in-depth into the expectations for the course and national exam. Hopefully, your school will pay for your attendance, because it is expensive. However, even if you have to pay out of pocket I would still recommend attending. The resources and knowledge you gain are far worth it – this is the number one thing all AP Physics teachers should do!

2. Join Pretty Good Physics

The previous AP teacher at my school told be about this site, and then I learned about it again at the APSI. It is a great place to find resources, share resources, and get ideas for your course.

There is a general wiki that has labs, activities, and various problem sets. This site is publicly view-able. There is also a secure site in which you must prove you are a teacher – secure includes test questions, FRQs, practice national exams, and so much more. I recommend joining both wikis.

3. TIPERs are your best friend

TIPERs, or Tasks Inspired by Physics Education Research, are a life saver. I find that these exercises tend to be pretty close to what students encounter on the national exam, and they are also just great problems. My students get an FRQ every week, and many times that FRQ is actually a TIPER. There are so many to choose from.

TIPERs are a great resource for AP Physics teachers

One type of exercise is a ranking task, in which students analyze six or so different scenarios and have to organize them based on most velocity, most kinetic energy, etc. The national exam has included these types of questions, as evident by 2017 AP Physics 1 FRQ #1.

You can find the book on Amazon, but I recommend getting an electronic version.

Here is an article on College Board’s website on using TIPERs and similar ranking tasks in your classroom. They also included this sample ranking task on projectiles.

4. Use the released practice exams

The released exams are my exams. Make sure you get access to the AP Audit website and secure documents. These documents can be used for in-class use, but may not be posted online or provided for students to take home. This makes they excellent test questions – they are secure and have actually been on the national.

The first thing my students said to me after the national was that it was not any harder than what we did in class. Sure, it was hard, but they were adequately prepared. Released exams are your best resource for preparing your students.

5. Do all the labs

Seriously, all of them. Okay, maybe not all, but at least 1-2 a week. 25% of your class should be time spent in laboratory experiences. This may sound like a lot and you may say that you don’t have time, but it is absolutely necessary. I teach in a school with 50 minute class periods. It is possible.

It is important to vary between the types of labs students perform. You can do inquiry-based labs, traditional step-by-step labs, design challenges, virtual labs, create models, whatever – the point is that students need their hands on things for Physics to make sense. I posted about how I use labs in my AP Physics course to help with the experimental design FRQ – check it out here!

Data tracking for AP Physics

I previously shared that I started doing Multiple Choice Mondays and FRQ Fridays every week going into the AP exam. Here is a sample score tracking sheet my students used to track their progress. It was helpful and motivating for them to see their progress over time.

AP Physics Pass Rate Reflections

How much does your AP Physics pass rate matter as a teacher? I started teaching AP Physics 1 two years ago. I was scared. The national pass rate was appallingly bad and I was afraid to push a course that no one could pass on my students.

Here is some data from the 2016 AP Physics 1 exam courtesy of Total Registration

I feel very different after teaching it and getting through two National Exams.

What does the national AP Physics pass rate tell us?

I firmly believe that the national pass rate does not accurately reflect the course. If you look at the numbers, many many more students took AP Physics 1 than the old B exam. Schools seemed to have pushed AP Physics on too many unprepared students. Additionally, I have heard tales of freshmen taking it, of schools completely abolishing all Physics but AP, and offering 1 and 2 in the same year. I think all of these things artificially deflate the AP Physics pass rate.

What’s the big difference in the newer course? Less rote memorization and plug-and-chug. More analysis and critical thinking. These are important skills that I hope my students take away from the course. I always say that Physics teaches you how to think. For instance, I’d rather my students remember how to think than recite a definition. I posted here about how I rethought my classroom to make it more student-centered – these types of strategies are definitely important to adjust our teaching to include inquiry and critical thinking.

My hypothesis is that the national pass rate will slowly rise to 50% or so as teachers learn the test and students are able to more adequately prepare. Also, it will take time for teachers and students to adjust to the new exam format. , This exam has almost no calculations and hopefully will create change overall in how Physics is taught. Physics education as a whole seems to be moving towards conceptual understanding, inquiry, and a more hands-on approach. Only time will tell. My biggest fear is that students will see the pass rate and not take the class. They’d be missing out on an amazing adventure.
