About This Topic

This topic explores the 'Second Founding' of America through the 14th Amendment and the doctrine of Selective Incorporation. Students learn how the Supreme Court used the Due Process Clause to gradually apply the Bill of Rights to state governments, case by case. They also examine the Equal Protection Clause as the constitutional engine for modern civil rights movements.

For 12th graders, this is the most important legal concept for understanding why state laws must respect federal rights. It connects the 1791 Bill of Rights to the 1868 14th Amendment and the 20th-century rights revolution. This topic comes alive when students can physically model the patterns of legal expansion by 'incorporating' different amendments through a historical timeline activity.

Active Learning Ideas

Inquiry Circle: Incorporation Timeline

In small groups, students are assigned a specific amendment (e.g., 2nd, 4th, 8th). They must find the landmark Supreme Court case that 'incorporated' it and explain how the law changed in their state after that ruling.

Formal Debate: Total vs. Selective Incorporation

Students debate whether the Supreme Court should have 'totally' incorporated the Bill of Rights all at once in 1868, or if the 'selective' (case-by-case) approach was a better way to respect federalism.

Gallery Walk: The 14th Amendment's 'Children'

Display various modern rights (e.g., marriage equality, desegregation, birthright citizenship). Students rotate to identify how each 'child' was born from either the 'Due Process' or 'Equal Protection' clause of the 14th Amendment.

Watch Out for These Misconceptions

Common Misconception

The Bill of Rights has always applied to the states.

What to Teach Instead

Originally, it only applied to the *federal* government (Barron v. Baltimore). Peer-led 'Before and After' comparisons of state power help students realize that for most of US history, states could legally restrict speech or religion.

Common Misconception

The 14th Amendment only applies to formerly enslaved people.

What to Teach Instead

While that was the original intent, the wording 'any person' has allowed the Court to protect immigrants, corporations, and all citizens. Peer discussion about the 'universal' language of the amendment helps clarify its broad reach.

Frequently Asked Questions

What is 'Selective Incorporation'?

It is the process by which the Supreme Court has applied most, but not all, of the Bill of Rights to the states. They do this by ruling that a specific right is 'fundamental' to the concept of liberty under the 14th Amendment's Due Process Clause.

Which rights are still NOT incorporated?

A few rights, like the 3rd Amendment (quartering soldiers), the 5th Amendment's right to a grand jury indictment, and the 7th Amendment's right to a jury trial in civil cases, have not yet been applied to the states.

How can active learning help students understand the 14th Amendment?

The 14th Amendment is the 'bridge' between the Founders and us. Active learning, like a 'Case Law Scavenger Hunt,' helps students see this bridge being built brick-by-brick (case-by-case). When they have to 'map' the 14th Amendment to a specific right like 'the right to a lawyer,' the abstract legal doctrine becomes a concrete historical story.

What is the 'Equal Protection Clause'?

It is the part of the 14th Amendment that prohibits states from denying any person 'the equal protection of the laws.' It is the primary tool used to challenge discriminatory laws based on race, gender, and other characteristics.
