5 Ways to Build a Language-Rich STEM Environment

Have you ever seen a student's eyes glaze over when you introduce a term like "photosynthesis" or "algorithm"? In STEM (science, technology, engineering and mathematics), language can feel like a barrier. As educators, our greatest opportunity is to transform it into a bridge.

In a language-rich STEM environment, learners think critically, communicate effectively and innovate creatively. By combining language development into each STEM lesson, we equip learners to understand complex concepts and articulate their ideas with confidence.

Here are five ways to build a language-rich STEM environment:

1. Go Beyond the Glossary: Teach STEM Vocabulary for Deep Understanding

A strong understanding of the key terms used in a lesson increases engagement and builds confidence. Repeated exposure through varied methods ensures retention and practical application.

✏️ Introduce vocabulary through multiple modes:

• Visuals: Show time-lapse videos, physical models or diagrams.
• Hands-On Activities: Conduct experiments where students observe and interact with concepts.
• Digital Media: Use simulations and interactive tools.

✏️ Revisit key terms regularly:

• Incorporate quick reviews at the start of new units.
• Use vocabulary games or student-created glossaries.
• Create word walls.
• Encourage learners to use new vocabulary in discussions and responses.

In Dirt Camp, learners explore the vocabulary of soil science not just through definitions, but by engaging all five senses to describe soil properties, fostering a deep and multi-sensory understanding of terms like "topsoil" or "loam."

2. Foster Collaborative STEM Discussions to Enhance Learning

Learning is social, and STEM is no different. Collaborative talk offers a low-stakes way for learners to explore ideas and refine understanding.

✏️ Facilitate pair and group discussions:

• Pair and share: After a demonstration, have learners explain concepts to a partner.
• Provide sentence starters to help articulate thoughts (e.g., "My hypothesis is based on..." or "One advantage of this design is...").

✏️ Embrace diverse perspectives:

• Learners hear different ways to articulate concepts, expanding their vocabulary.
• Encourage rephrasing ideas or constructive challenges.

In Drone Designers, learners are introduced to a rich vocabulary related to drones. Through video analysis, structured group discussions and "pair and share" activities, they become comfortable using their newfound "drone lingo" to explain mechanics and flight principles.

3. Make STEM Concepts Visible for Deeper Understanding

Abstract STEM concepts can be challenging. Making thinking visible reveals the logical processes and language connections experts use.

✏️ Use think-alouds:

• Narrate your thought process when solving a math problem (e.g., "First, I identify variables...").
• Articulate inferences when interpreting data (e.g., "Looking at this rising line, I infer that as temperature increases, solubility also increases...").

✏️ Utilize diagrams and anchor charts:

• Create detailed anchor charts with labeled diagrams and key vocabulary (e.g., "water cycle" terms).
• Students can refer to these when explaining concepts or writing.
• Flowcharts or molecular structure diagrams with labels also clarify abstract ideas.

✏️ Implement visible thinking routines:

• "Think-Pair-Share" is a low-stakes method for learners to verbalize observations and questions, linking thoughts to specific language.

In Oceanic Exploration, learners become water molecules through a kinesthetic activity, helping them embody the process. This concrete experience is coupled with visual diagrams and hands-on experiments to truly embed the vocabulary and concepts of the water cycle.

4. Connect STEM Language to Real-World Applications

When learners see STEM language applied daily, it becomes immediately relevant and less intimidating.

✏️ Relate vocabulary and concepts to everyday experiences:

• "Gravity" can be linked to jumping or throwing a ball.
• "Density" can be explored by comparing a golf ball and a ping-pong ball.
• "Force" connects to pushing a shopping cart or riding a bike.

✏️ Describe familiar phenomena:

• Show how "erosion" describes how a river carves a valley.
• Explain how "insulation" keeps a thermos warm.
• Daily application of STEM vocabulary makes academic terms feel like necessary tools for understanding their world.

In BrickLAB Famous Architecture, learners step into the role of architect. They learn the specialized language, from "flying buttresses" to "arches," by actually constructing these structures. This hands-on building provides an unparalleled context for understanding and retaining architectural vocabulary.

5. Support English Language Learners (ELLs) in STEM Classrooms

ELLs bring valuable multilingual abilities. Embrace these as assets and provide targeted support.

✏️ Provide visuals:

• Use labeled diagrams, manipulatives, videos and interactive simulations.

✏️ Offer translated glossaries:

• Help students connect new English terms to their existing linguistic knowledge.

✏️ Prioritize hands-on learning opportunities:

• Concrete experiences often precede or accompany linguistic input.

✏️ Celebrate multilingual abilities:

• Encourage ELLs to share how scientific concepts are expressed in their native languages.
• Allow discussion in their first language before transitioning to English.

PCS Edventures is proud to offer Spanish materials in three of our popular STEAM Enrichment Programs, directly supporting our ELL learners and fostering a more inclusive learning environment.
