3DE: JA High School

3DE is an innovative approach that is transforming the high school experience.

In a 3DE program, the learning experience is re-engineered to be authentically connected to the world that exists beyond the classroom walls. By giving education real-world context, this program empowers, inspires and better prepares students for life after graduation. The 3DE learning model incorporates the Four Cs.

Teachers and students are grouped into small cohorts, which builds a sense of comradery and trust. 3DE coursework is supported by an interdisciplinary team of five to eight teachers. This self-contained structure helps students boost their confidence and engagement.

Learning and curriculums are built around real-world, real-time business case challenges from regional and national companies. Students then use core subjects like math and English to solve the cases. This approach connects students with local business professionals and makes lessons more relevant, memorable, and engaging.

3DE encourages student collaboration through small group discussions and facilitated debates. This approach boosts social and emotional skills and closely mimics the real world.

By centering an interdisciplinary curriculum, including core academics, around case challenges, 3DE doubles the learning opportunities of a traditional classroom. The 3DE model helps students develop valuable 21st-century skills by encouraging creativity, cultural agility, critical thinking, collaboration, problem-solving and self-direction.

Your business partnership can transform our region.

Because real-world case challenges form the core of the 3DE model, participation from regional businesses is essential. Businesses and local professionals are initially invited into the classroom to introduce case challenges and provide background on their company. As the projects come along, they come back to check in with students during the challenge, observe students’ final presentations and select a case challenge winner.

3DE strengthens our regional economy by:
• Helping businesses build relationships with potential future employees.
• Giving graduates both a diploma and a certification.
• Fueling skills that drive economic competitiveness.
• Generating thousands of workforce-ready graduates.
• Improving talent retention in our region.
• Reaching ALL students, not just the highest achievers.
• Exposing students to a variety of real-world career pathways.
• Preparing students for a rapidly changing economy.
• Expanding students’ opportunities after graduation.
