Watson-Glaser Critical Thinking Appraisal (WGCTA) – Short Version

 

Great! The Watson-Glaser Critical Thinking Appraisal (WGCTA) – Short Version focuses on assessing core critical thinking skills, usually through 5 subscales:

1. Inference – Ability to draw logical conclusions from given information.
2. Recognition of Assumptions – Ability to identify unstated assumptions.
3. Deduction – Ability to apply general rules to specific cases.
4. Interpretation – Ability to understand and weigh evidence.
5. Evaluation of Arguments – Ability to distinguish strong vs. weak arguments.

Here’s a short questionnaire version (10 items, 2 per subscale) in English:

No	Subscale	Item	Response Options
1	Inference	If all teachers in this school are friendly, and Mr. John is a teacher, then Mr. John is friendly. True or False?	True / False
2	Inference	Sarah studies hard. If she studies hard, she will pass the exam. Therefore, Sarah will pass the exam. True or False?	True / False
3	Recognition of Assumptions	“We should cancel the picnic because it might rain.” What assumption is made? a) The picnic cannot proceed in rain, b) Everyone likes rain, c) Rain is always bad	a / b / c
4	Recognition of Assumptions	“All employees should attend the workshop to improve productivity.” Assumption: a) Attendance improves productivity, b) Some employees are unproductive, c) Workshops are boring	a / b / c
5	Deduction	All cats are mammals. Bella is a cat. What can you conclude? a) Bella is a mammal, b) Bella is a dog, c) Bella is a reptile	a / b / c
6	Deduction	If it rains, the ground will be wet. The ground is wet. Can we conclude it rained? a) Yes, b) No, c) Maybe	a / b / c
7	Interpretation	A survey shows 80% of students prefer online learning. Does this mean online learning is better than offline? a) Yes, b) No, c) Cannot tell	a / b / c
8	Interpretation	John scored higher than Mary in the test. Can we say John is smarter than Mary? a) Yes, b) No, c) Cannot tell	a / b / c
9	Evaluation of Arguments	“Using smartphones in class helps learning because students can search for answers quickly.” Strong or Weak argument?	Strong / Weak
10	Evaluation of Arguments	“We should ban homework because it is boring.” Strong or Weak argument?	Strong / Weak

✅ Scoring suggestion (short version):

• Count correct answers for Inference, Deduction, Interpretation.
• Count correctly identified assumptions for Recognition of Assumptions.
• Count correct evaluation for Evaluation of Arguments.
