Flash-based tools - Conditional tools: 4 Card / Beer Coke | |||||
| Examples of Wason's 4-Card task, with an practicale example that should stick in the students's heads. Finally, a few twists on conditional reasoning truth-tables (necessary / sufficient / contraposition). | |||||

The Four Card Problem - version 1 This is a simple demonstration of the 'four-card' problem often used to teach conditionals. In this case, 35 cards are presented, each with a number on one side and a letter on the other. Students are asked to determine if the statement 'If a card has a vowel on one side, it has an even number on the other' is true of this set of cards. Turning over a card costs $10, and getting the problem correct rewards $200. The conditional is false. Turing over the '3' card yields and 'I'. hide description |

The Four Card Problem - version 2 This is a simple demonstration of the 'four-card' problem often used to teach conditionals. In this case, 35 cards are presented, each with a number on one side and a letter on the other. Students are asked to determine if the statement if a card had an even number on it, it has a consonant on the other side.' is true of this set of cards. Turning over a card costs $10, and getting the problem correct rewards $200. The conditional is true. hide description |

The Four Card Problem - version 3 This is a simple demonstration of the 'four-card' problem often used to teach conditionals. In this case, 35 cards are initially presented, each with a number on one side and a letter on the other. However, in this version, each card is replaced after it is turned over. Students are asked to determine if the statement 'if a card does not have a consonant on it, it does not have an even number on the other side.' is true of this set of cards. Turning over a card costs $10, and getting the problem correct rewards $200. The conditional is false. Turning over the 'U' card yields an '8'. hide description |
