Quill Lane Challenge Stems

A Fast-Paced Debating Club Game for Noun Clauses & Logical Fallacies

Duration 25 Mins
📜

Rules of the Game

👩‍🏫 Teacher Setup & Execution

For Teacher
  1. 1 Divide the class into debating teams of 3 or 4 students.
  2. 2 Hand out one set of 6 Claim Cards and a challenge sheet to each team.
  3. 3 Appoint one dedicated scorekeeper per team to track points accurately.
  4. 4 Instruct Team A to read a claim aloud, while Team B gets exactly 60 seconds to complete the stem.
  5. 5 Keep time strictly and consult the Teacher Key for word order and scoring rules.

🎓 Student Round Mechanics

For Students
  1. 1 Goal: Challenge weak reasoning using correct noun clauses and unit vocabulary.
  2. 2 One member reads the Claim Card clearly to the opposing team.
  3. 3 The responding team has 60 seconds to construct a coherent noun clause completion.
  4. 4 Use statement word order (Subject + Verb). Never include auxiliary do or does!
  5. 5 Win 2 points for correct word order, 1 point for minor order errors, plus 1 bonus point per Unit word used.

Correct Word Order

Sensible challenge with statement word order (Subject + Verb). No auxiliary do/does/did inside the clause!

1pt

Flawed Word Order

Sensible critical response, but contains a minor word order slip (e.g., using question word order inside the clause).

+1

Sentence Starters (Grammar + Vocabulary Bank)

Use these 6 high-level model sentence starters during debate rounds. Each item incorporates target C1 critical thinking vocabulary alongside wh-/whether/if noun clauses:

Card 1 Model premise plausible

"What worries me is whether this basic premise is actually plausible."

Card 2 Model assumption

"It is not clear why the author relies on such a flawed assumption."

Card 3 Model inference rationale

"We should ask what else could explain this, since the inference has no coherent rationale."

Card 4 Model fallacy

"No one has explained how this single survey avoids a logical fallacy."

Card 5 Model rigorous scepticism

"Whether looking old proves anything requires more rigorous scepticism."

Card 6 Model paradox

"Why the water never dries up is a classic paradox that needs study."

Teacher Key & Assessment Guide

📌 Grading Criteria & Flex Guidelines

Any sensible critical challenge that preserves standard statement word order (Subject + Verb) inside the clause is FULL MARKS (2 pts). Note that Cards 5 & 6 require subject clauses positioned directly before the printed verbs (is / remains).

Card 1 Model

"What worries me is whether five swans are enough to prove it."

(Alt: "whether this premise is plausible.")
Card 2 Model

"It is not clear why member opinions count as a coherent rationale."

Card 3 Model

"We should ask what else changed that year."

Card 4 Model

"No one has explained how twelve tea-lovers represent a rigorous sample."

Card 5 Model (Subject Clause)

"Whether looking old proves anything is the real question."

Card 6 Model (Subject Clause)

"Why the water never dries up remains to be explained."

⚠️

Mistake to Hear & Correct Immediately

Listen out for students using question word order inside embedded clauses, e.g.:

❌ Incorrect: "We should ask what did else change."

✅ Correct: "We should ask what else changed."

🔀

Activity Variations & Differentiation

Level 1: Easy

Warm-Up Mode

Give teams 30 seconds of quiet prep time to write down their noun clause before speaking it aloud.

Level 2: Medium

Standard Rules

Strict 60-second timer per claim. Fully spontaneous verbal responses with no writing allowed.

Level 3: Hard

Philosophy Expert

Require every answer to contain at least two C1 Unit words to earn the full 2 base points.

⚡ Fast Groups

Creator Challenge

Fast teams invent 2 original flawed claims and write matching stem cards to challenge adjacent teams.

❓

Closing Discussion Questions

Wrap up the session by discussing these 3 critical reflection questions as a whole class:

1

Which claim card contained the most obvious logical fallacy, and why?

(Encourage students to spot the idea that one thing caused another just because it came first in Card 3, and the mistake of trusting too few examples in Cards 1 & 4).

2

How does using a noun clause help us express scepticism in a formal debate?

(Focus on academic distance, objective tone, and avoiding aggressive direct attack language).

3

What is the difference in tone between asking a direct question and using a subject noun clause like 'Whether... is the real question'?

(Subject clauses elevate focus onto the argument itself rather than demanding an instant answer from the speaker).
