Three core concepts organizing introductory statistics: statistical model, distribution, and randomness¶

Description¶

In their introductory statistics textbook the authors selected three core concepts to organize the domain: statistical model (captured as DATA = MODEL + ERROR), distribution (following Wild, "the pattern of variation in a variable", including the sample data, data generating process, and sampling distributions of the distribution triad), and randomness as a data generating process. They state: "we chose to focus our textbook around three core concepts: statistical model, distribution, and randomness." Concepts were chosen for being connectable throughout the course, accessible to novices, not needing later unlearning, and jointly supporting coherent understanding.

Design Implications¶

Context¶

Requirements¶

Core concepts must be accessible to novices within their zone of proximal development
Concepts must not need to be unlearned later and must form a coherent whole without introducing misconceptions

Constraints¶

Concepts introduced to novices are almost always simplified in complex domains, and the authors warn against simplification that yields a collection of concepts failing to form a coherent whole

Target Learners¶

Novice students in introductory statistics at the college level

Learning Goals¶

Coherent conceptual understanding of statistics that transfers to advanced courses and data analysis practice

Claims¶

The practicing connections framework: instructional design organized around three connection types and three design principles
