6 tips for teaching evolution in high school biology

Ever heard someone ask, "If we evolved from monkeys, how come there are still monkeys?" Or the classic line, "Evolution is just a theory." I mean, seriously? Let's face it, there are some serious misconceptions about evolution floating around, and it's time to set the record straight. So, buckle up because we're diving right into the heart of the matter. No pointing fingers, just good ol' fashioned understanding. We'll tackle everything from the basics to the nitty-gritty, because who doesn't want to get what evolution is all about? And don't worry, if you're feeling a bit uncertain about this whole evolution thing, especially with beliefs that lean towards a young Earth, we've got your back. Let's address those concerns head-on and unravel the mysteries together. So, grab a seat and get ready to clear the air on evolution!

1. Address Misconceptions Head-On

You know, I've heard that "If we evolved from monkeys, how come there are still monkeys?" question more times than I can count. And then there's that other idea that keeps popping up, "Evolution is just a theory." I mean, seriously? That shows some folks haven't quite got the hang of what a scientific theory actually is. There are a number of misconceptions about evolution, which is why those need to be addressed from day one.

But hey, we're not here to point fingers. We're here to set things straight. Let's dive right in from the get-go. I've got a little mantra for my students: "It's totally cool if you don't agree with evolution, but let's make sure you actually get what it's all about." Because honestly, misunderstandings about evolution can create some pretty tangled debates.

Now, I get it. Some students might be a bit uneasy about this whole evolution thing, especially if their background leans toward a belief that the Earth is only about 6,000 years old. It's cool, we're all coming from different places. So, let's be proactive and deal with these concerns head-on. We're talking about misconceptions, fears, and all those questions that might be bouncing around.

Here's a little trick I've got up my sleeve. I hand out this pre-survey to my students. I use pre-survey in many of my products, most notable the cross-cultural slave trade project requires a lot of introspection on the part of students. Its also true for evolution. It's got a bunch of statements on it, and they have to decide if they're true or false. Every single one of them is false. Sneaky, right? But they're also some of the most common misconceptions I've come across. This little survey gives us a starting point to dive into the nitty-gritty and sort things out. It's all about building that understanding and smoothing out those uncertainties. So, yeah, we're clearing the air, right from the very beginning.

2. Highlight the Population Perspective

Central to comprehension is grasping that individuals don't evolve—populations do! This principle is pivotal. Instill this concept early, as it dispels numerous misconceptions. Natural selection acts on heritable traits, shaping a population's gene pool over time. Repeat this mantra often, allowing it to permeate your students' understanding of evolution's mechanics.

3. Witness Evolution Through Simulations

Unlocking evolution's secrets often hinges on simulations. These simulations are your trusty companions in cultivating understanding, and there are a few online simulations you can incorporate into the classroom. The iconic bird beak simulation remains a visual highlight, demonstrating natural selection's workings. For a more controlled virtual approach, explore online simulations like the peppered moth example. These tools immerse students in evolution's dynamics while avoiding utensil-wielding chaos.

4. Connect with Real-World Examples

Evolution thrives on real-world examples—use them abundantly. For example, one thing you could do is teach students about the evolution of viruses: influenza is the perfect example. Why do we need a new flu shot each winter? That is because influenza evolves. Covid-19 evolves, HIV evolves and many pests evolve resistance to pesticides. You can also explain to students that when the doctor prescribes antibiotics, they need to take the entire bottle, not just take the meds until symptoms go away. Germs evolve – even inside of us.

And get this—when the doctor gives you antibiotics, it's like handing the germs an ultimatum: "Take this entire bottle or face the consequences!" Germs inside our bodies are evolving too. They're like little shape-shifters trying to outsmart us. It's like a science fiction story happening inside us.

Showcase the wonders of evolution unfolding in our lifetime. Don't miss the chance to present the captivating evolution narratives that surround us. PBS's "Evolutionary Arms Race" video, peppered moth demonstrations, and the evolution of antibiotic-resistant bacteria stand as captivating exemplars. These real-world instances breathe life into classroom learning.

5. Welcome Multiple Voices

Evolution education isn't a solo journey. Capitalize on diverse voices to reinforce key points. Acknowledge that students often carry misconceptions into the classroom. Embrace a multitude of external videos and resources to broaden their perspectives. Encourage students to engage with different sources through station activities, ensuring they glean insights beyond the confines of your instruction.

6. Foster Open Conversations

Creating a culture of dialogue is paramount. Encourage open conversations, even when the topics are challenging. Cultivate an environment where students feel at ease expressing their questions and concerns. Acknowledge that it's okay not to have all the answers. Embrace humility and guide students towards researching and discovering answers independently. The willingness to listen and guide holds immense value.

Embracing these six strategies empowers you to orchestrate an enriching evolution education experience. With careful attention to misconceptions, population perspectives, simulations, real-world connections, varied voices, and open dialogues, you nurture a classroom environment that celebrates inquiry, exploration, and growth.
