Writing Argumentative Essays

Objectives of the Remodelled Plan

The students will:

  • develop their perspectives through dialectical exchange, writing, and argument analysis and evaluation
  • clarify issues and key words
  • evaluate evidence
  • practice critical thought by writing and revising argumentative essays

Standard Approach

Students pick an issue or position and find reasons to support their conclusions. Sometimes students are told to state and refute opposing arguments. They research their topics, noting facts supporting their positions. Sometimes texts introduce fallacies and a bit of logic as preparation. Students write an argumentative essay, defending their positions.

Critique

Though this handbook mainly focuses on incorporating critical thinking into other lessons, lessons specifically on critical thinking can also be useful. Generally, texts' treatment of argumentation suffer from many serious flaws and misunderstandings, display fuzziness of thought, misuse terms, and lack critical insight. As a whole, texts downplay evaluation of reasoning. (Where mentioned or suggested, they give little guidance and often use confusing language). They rarely suggest evaluating the relevance of support to conclusions.

Texts mainly focus on how to defend opinions, not how to shape them more reasonably. Though they address the importance of giving reasons for beliefs, they often neglect the importance of considering opposing views, or strengthening one's reasoning by weeding out or altering unjustified beliefs. Presenting good reasons, though valuable, is only half of a discussion. The standard approach allows reactions that are too often impressionistic and based on prejudice or lack of understanding.

Rather than teaching argument analysis and evaluation, texts generally have students attempt to distinguish fact from opinion. Though the motive of having students distinguish questionable from acceptable claims is worthwhile, the usual approach does not accomplish this purpose. It produces an unquestioning attitude of acceptance for statements that seem factual, though factual (empirical) claims are not necessarily reliable, and students can't necessarily tell if so-called facts are true. Facts, when used in an argument, may not be complete or relevant. Since statements students are called on to judge as opinions are given without context, students cannot rationally judge whether they are mere whim or can be well defended. Rather than using the fact/opinion distinction, students can distinguish questionable from acceptable claims and fact from interpretation and judgment.

develop students' use of critical vocabulary by having them rephrase the model arguments into explicit premises, assumptions, and conclusions. To have students identify the conclusion of each model, ask, "What is the conclusion? What is the point of the argument? What statement is this argument trying to convince you to believe? Is the conclusion stated or implied?" Then ask, "What reasons are given? Is the reasoning complete, or is there a hidden claim, or assumption?"

Critical Thinking Problems

1. There is a building and in one of the rooms there is a table.  On that table there is bowl and in the bowl there is an orange.  You walk into the room and see two different hands grabbing for the last orange.   The children start to fight.   What do you do?

2. It is a hot summer day and you are very thirsty.  You open the door of the refrigerator to get your bottle of water and it is frozen.  For some reason the refrigerator was turned up to the highest degree and froze everything in it.  You want the water now.  What should you do?

3. There is a classroom where four children are playing.  One child decides to play with his beanie babies and invites the others to join him.  He only has three manatees and one zebra with him.  You walk in as they start to play and after some time, all of them want to play with the manatees.  They start to argue.  How are you going to handle this?

4. There is an island the size of this room and all of you are stranded on it.  The main land is 1/16 of a mile away and there is a river of lava surrounding the island.  One of you finds a pair of magic shoes that can be used to walk across the lava and your feet will not burn.  The only problem is that each foot can only wear the shoe once, meaning, the right foot can only wear the right shoe once and one way and the same for the left foot.  You want to get everyone across with no injuries.  How are all of you going to get off the island?
