Active learning ideas

Constantine, Christianity, and the Late Empire

Active learning works well for this topic because students grapple with complex ideas like gradual policy changes and long-term historical shifts. Role-plays, debates, and mapping tasks help them visualise the human decisions behind these events rather than treating them as impersonal facts.

Activity 01

• Socratic Seminar
• 45 min · Small Groups

Role-Play: Council of Nicaea Debate

Assign roles as bishops, Constantine, and heretics to groups. Students research Arian controversy, prepare 2-minute arguments for or against key doctrines, then debate in a simulated council. Conclude with a class vote on the Nicene Creed and discuss its impacts.

Analyze how Constantine's conversion impacted the status of Christianity in the Roman Empire.

Facilitation Tip

For the Role-Play, assign roles in advance so students prepare with historical evidence and avoid modern biases in their arguments.

What to look for

Ask students to write two sentences explaining how Constantine's personal beliefs might have influenced his imperial policies. Then, have them list one potential advantage and one potential disadvantage of the Roman Empire's division for its citizens.

Activity 02

• Socratic Seminar
• 40 min · Small Groups

Collaborative Timeline: From Persecution to Power

In small groups, students sequence 10 key events on a large chart paper, adding visuals and quotes from primary sources. Each group presents one segment, linking events to Constantine's policies. Debrief on cause-effect chains.

Evaluate the reasons behind the division of the Roman Empire into East and West.

Facilitation Tip

For the Collaborative Timeline, provide clear cut-off dates (e.g., 312 AD, 313 AD) to prevent students from rushing through key events.

What to look for

Pose the question: 'Was the division of the Roman Empire an inevitable outcome or a deliberate choice?' Facilitate a class discussion where students use evidence from the lesson to support their arguments, considering factors like leadership, economic disparity, and military pressures.

Activity 03

• Formal Debate
• 50 min · Whole Class

Formal Debate: Reasons for Empire Division

Divide class into two teams: one arguing military/economic causes, the other cultural/religious factors. Provide evidence cards, allow 5-minute prep, then 20-minute debate with rebuttals. Vote and reflect on historical validity.

Explain the long-term consequences of the Edict of Milan for religious freedom.

Facilitation Tip

For the Debate, give students a pre-debate task to list three supporting points using primary sources to keep arguments grounded.

What to look for

Provide students with a short, primary source excerpt related to the Edict of Milan or the Council of Nicaea. Ask them to identify the main purpose of the document and one group that would have benefited from its provisions.

Map Marking: East-West Split

Pairs mark the 395 AD division on outline maps, labelling capitals, key battles, and trade routes. Annotate stability factors for each half, then share findings in a gallery walk.

Analyze how Constantine's conversion impacted the status of Christianity in the Roman Empire.

Facilitation Tip

For the Map Marking, use a large classroom map and coloured pins so students physically see the division’s impact on territory.

What to look for

Ask students to write two sentences explaining how Constantine's personal beliefs might have influenced his imperial policies. Then, have them list one potential advantage and one potential disadvantage of the Roman Empire's division for its citizens.

A few notes on teaching this unit

Teachers should emphasise that Constantine’s policies developed slowly and that imperial policies were often pragmatic rather than ideological. Avoid presenting the Edict of Milan as a sudden revolution; instead, frame it as a turning point in a longer process. Research shows that students retain more when they trace gradual changes through primary sources and debates.

Successful learning looks like students sequencing events accurately, weighing multiple causes for decisions, and explaining how policies evolved over time. They should connect Constantine’s personal journey with broader imperial consequences and analyse sources with nuance.

Watch Out for These Misconceptions

• During the Role-Play: Council of Nicaea Debate, watch for students claiming Constantine instantly converted after Milvian Bridge and made Christianity the sole religion right away.

  During the debate, ask students to refer to their timeline notes when others make this claim, prompting them to correct it by pointing to the Edict’s tolerance and Theodosius’s later decree.

• During the Debate: Reasons for Empire Division, watch for students oversimplifying the split as just a size issue or a single event.

  During the debate, have students refer to the map they marked, asking them to list at least three pressures (invasions, economics, administration) before stating the 395 AD division.

• During the Collaborative Timeline: From Persecution to Power, watch for students assuming the Edict of Milan granted equal freedom to all faiths.

  After the timeline is complete, ask groups to analyse the Edict’s wording and highlight which groups benefited most, then discuss why others remained tolerated but not prioritised.
