Two children working together to make things

5 Collaborative Strategies for STEM Learning

The skills we want to help young students develop don’t just include those directly connected to the subjects being taught. Modern science standards give guidance on how students should investigate matter, forces, and living things, of course, but they also emphasize skills like working in teams, collaboration, and engaging in argument from evidence. But what makes these such a crucial part of well-rounded science classes?

Science lessons—even virtual ones—provide great opportunities to give students investigative problems they must work together to solve. The engineering design process is a perfect opportunity to encourage students to team up, develop and test ideas, appreciate each other’s creativity, and talk about their successes and failures.

As students work in teams, they’re learning to communicate, to respect the ideas of others, and to understand why everybody’s role is important. These are essential aspects not only of classroom collaboration, but also of being part of society. Good teamwork improves students’ social skills. It makes them more self-confident. It even reduces bullying. And it helps children to go on to become successful adults.

That’s why we made teamwork, communication, and collaboration fundamental components of the Twig Science program. It’s there in all of our story-driven investigation modules, and we also created special 3-D Team Challenge mini-modules totally focused on teambuilding and how scientists and engineers work in teams. In doing so, we came up with some useful ideas for increasing the collaborative value of lessons that we thought we’d share with you—you’ll find all of these in the Twig Science Team Challenges and investigations, but they can be adapted for any lesson.

Here are our favorite five ideas:

1. Student-agreed “Science Expectations”—Children hate being told what to do when they don’t understand why they’ve got to do it.

It’s a good idea to get students to discuss the factors that create a productive learning environment. Guide them to come up with their own ideas for how investigations should be carried out in an environment that encourages collaboration and respect. Children hate being told what to do when they don’t understand why they’ve got to do it—but if they are included in creating the rules, they respect and learn from them. Twig Science mini-modules include sections where students brainstorm “Science Expectations.” They think about what good teamwork involves and how it could work better, and they produce a Science Expectations poster to display in the classroom throughout the year. Examples of Science Expectations could include “We respect each other,” “We let everyone share their ideas,” “We encourage each other,” or “Everyone helps to clean up.”

2. Team-building exercises—Prepare students for just about every situation they’ll ever encounter in their professional and personal lives!

Before getting students to embark on in-depth, full-length engineering investigations, it can be helpful to have them take part in shorter, low-stakes team-building exercises. In Twig Science mini-modules, we suggest various icebreaker activities, storytelling games, and classroom discussions. These get students engaging in civil discourse, deliberating, debating, building consensus, compromising, communicating effectively, and giving presentations. These are incredibly valuable skills that not only prepare students for the long-form storyline investigations that make up the main Twig Science modules—they prepare them for just about every situation they’ll ever encounter in their professional and personal lives!

3. Reflection points – Students review and discuss their work as a form of self-assessment.

Involving students every step of the way in thinking about what they’re doing, why they’re doing it, and how they could do it better helps to embed the skills that they are developing. We made sure to put frequent reflection points in Twig Science to give students a chance to discuss how teams are working together and whether everyone is getting their chance to take part. The important thing about reflection is that it’s a form of self-assessment. You’re not grading the students, and there are no correct or incorrect responses. The purpose of the discussion is for students to think about the investigation processes and to share and reflect on different ideas. What have they enjoyed? What was easy and what was challenging? How do their experiences in their teams connect to experiences outside the classroom?

4. Real-world connections –  Get students acting out behaviors that they’ll be able to use again and again throughout their lives.

A big part of Twig Science’s collaborative investigations is how they connect to the way real-life scientists and engineers work in teams. Giving students this real-world connection adds meaning and purpose to what they’re doing. As they take on the roles of scientists and engineers, they’re acting out behaviors that they’ll be able to use again and again throughout their lives. They’ll understand that scientists, too, have team roles. They listen to each other. They’re respectful when they disagree. They build on each other’s ideas. Students will associate these attitudes with success as they act them out and become used to recognizing them in the world around them.

5. Language routines – Communication is a fundamental component of teamwork.

How students use language is an important indicator of their levels of understanding and respect. Communication is a fundamental component of teamwork, which involves a careful balance of being able to express ideas and opinions and also listen to those of others. It’s directly connected to our social and emotional development because language is our primary method of expressing what we feel about ourselves and each other and describing what we agree and disagree about. Twig Science includes a number of repeated language routines (e.g. Turn and Talk, Collect and Display) that structure the way students use language in investigations. They’re encouraged to use the words they feel comfortable using—without the need for formal “perfection”—while given the support to connect these to scientific vocabulary when they’re ready. The language routines support English Learners—and other students who lack confidence—to take part fully in discussions. Communicating in an inclusive, encouraging, understanding environment leads to confidence, and confident communication increases students’ ability to work well as team members in the classroom and as successful and respectful citizens.

Anchor Phenomena and Investigative Phenomena in Twig Science

In Twig Science, every module has a storyline that sets its module anchor phenomenon in a grade-appropriate context. The storyline is introduced near the start of each module through a module trailer video. This video is not a replacement for complex observable events that students must investigate to solve or explain, but an engagement tool to get students excited about the challenges and phenomena they are about to explore.

Every module’s anchor phenomenon is scaffolded through a sequence of smaller investigative phenomena and problems, known as Driving Questions in Twig Science.

In every grade and every module of Twig Science, observing and explaining phenomena and designing solutions provide the purpose and opportunity for students to engage and drive their own learning.

Grade 4, Module 3: Time-Traveling Tour Guides

For example in Grade 4, Module 3, students make sense of the module anchor phenomenon: How have weathering and erosion sculpted some of Earth’s most interesting landscapes?

As per our instructional design, the investigation of this anchor phenomenon is resolved over several weeks of instruction. The students’ first exposure to it is carried out at local level in the module’s first lesson, when students take part in an outdoor investigation in their schoolyard, recording their observations for changes that might have occurred over time.  Afterward, in a class discussion, they connect their findings to the first investigative phenomenon (Driving Question):  What makes landscapes change over time?  They begin to understand how landscapes change, and they identify water, wind, and ice as possible agents of those changes.

In Lesson 4, the scale of what they’ve seen and discussed changes both in terms of size and time as they explore geological features of the Grand Canyon.  Students observe 360-degree photographs of the Canyon. They generate wonderful questions about this phenomenon.   The module trailer video is shown in Lesson 4, introducing the storyline in which students take on the role of tour guides and explain what they learn about the Grand Canyon to visiting tourists.  

Students continue their investigation to explain the geological features of the Grand Canyon in subsequent Driving Questions.  

In Driving Question 2 (Why do we see different rock layers in the Grand Canyon?), students make physical models of layers of rock at the Grand Canyon containing different fossils within different layers.  Students come to understand that rock layers represent different periods of geological time and that layers further up the canyon are more recent.  They figure out that fossils help us understand what landscapes used to be like. Students begin to connect the component parts of a landscape and the evidence available to them as to how it was formed.

In Driving Question 3 (How did the Colorado River sculpt the Grand Canyon?), students make stream tray models to observe the phenomenon of how the movement of water causes erosion, connecting it to nature by looking at satellite photos. They figure out that water can change the land (including carving river channels) by modeling the water flow of a river in a stream tray and making observations. They figure out that there are variables (stream flow, steepness of slope) that affect the rate of erosion. Students have now investigated one of the key agents of erosion that sculpted the Grand Canyon. 

In Driving Question 4 (What other amazing landscapes have been sculpted by weathering and erosion?), students extend their investigations of landscape change beyond the Grand Canyon.  They explore the investigative phenomena How do wind and ice change the land? They use physical models to help investigate natural phenomena such as Yosemite Valley and connect their findings to real-world examples. They figure out that the movement of ice and the wind can dramatically change landscapes, finding evidence for this in the models they create: observing changes in clay when a block of ice is moved over it and in sand when blown by a fan.

In exploring these anchor and investigative phenomena in Time-Traveling Tour Guides, students revisit the topic of landforms, explored in Grade 2 in Twig Science, and investigate erosion and weathering. They also look ahead to the H2O Response Team module in Grade 5, in which they build on their Grade 4 ideas about how water and wind affect Earth.
