Chapters

This textbook is organized into 16 chapters covering 297 concepts from the learning graph. Chapters follow the UCLA Big Era framework (Eras 1–5) and respect the dependency relationships in the concept graph: every prerequisite concept appears in the same or an earlier chapter than the concepts that depend on it.

Chapter Overview

  1. Foundations of Historical Thinking — Establishes the Big Era framework, three thematic axes, AHA Tuning competencies, and the historical-thinking skills the rest of the book applies.

How to Use This Textbook

Chapters are designed to be read in order. Each chapter lists the concepts it covers (drawn from the learning graph) and the prior chapters whose content it builds on. If you skip a chapter, check its prerequisites first — later chapters assume you have already met the foundational concepts.

Note: Each chapter index lists the concepts covered. Chapter content (narrative, MicroSims, quizzes, references) will be added by downstream skills.
