你知道你的學生已經學會何時可以反過來解釋。 STELLA模型就能夠讓你了解系統如何工作-在發生的事情,系統如何受到影響,有什麼結果。

STELLA軟件是支持多樣的學習方式與範圍廣泛的講故事的特點。 圖表,圖表和動畫幫助視覺學習者發現變量之間的關係在一個公式。 言語學習者可以環繞視覺模型文字或附加文件來解釋一個新的環境影響的政策。

Education and research are most exciting when they move out of the lecture hall and library and provide opportunity to create, experience, and see. STELLA®offers a practical way to dynamically visualize and communicate how complex systems and ideas really work.

Whether they are first-time or experienced modelers, teachers, students, and researchers use STELLA to explore and answer endless questions like:

  • How does climate change influence an ecosystem over time?
  • Would Hamlet’s fate have changed if he’d killed Claudius earlier?
  • How do oil prices respond to shocks in supply and/or demand?
  • What will happen when the ozone layer is gone?
  • How do basic macroeconomic principles affect income and consumption?

The Gold Standard

Easy-to-use, STELLA models provide endless opportunities to explore by asking "what if," and watching what happens, inspiring the exciting ah-ha moments of learning.

Thousands of educators and researchers have made STELLA the gold standard; using it to study everything from economics to physics, literature to calculus, chemistry to public policy. K-12, college, and research communities have all recognized STELLA’s unique ability to stimulate learning.


Shared Learning

You know that your students have learned when they can, in turn, explain. STELLA models allow you to communicate how a system works – what goes in, how the system is impacted, what are the outcomes.

STELLA supports diverse learning styles with a wide range of storytelling features. Diagrams, charts, and animation help visual learners discover relationships between variables in an equation. Verbal learners might surround visual models with words or attach documents to explain the impact of a new environmental policy.
