TEACHING STRATEGIES IN SCIENCE TEACHING

THINK, PAIR AND SHARE (T.P.S.)
PURPOSE: Is a simple technique for getting students to think and communicate and to work together quickly. PROCEDURE: The teacher poses a question for students to think about. The students generate responses and share them with their neighbors. The teacher then collects the students’ ideas.

STEPS:
THINK, PAIR AND SHARE
1. Teacher poses a question.
2. Students think and construct a response.
3. Students share their ideas with a neighbor.
4. Teacher records students’ ideas.

EXAMPLE: Based on our demonstration, think about how the boiling of liquids is different from the freezing of liquids. Discuss your idea with your neighbor and be ready to share.

STEPS:
SURVEYING
1. Teacher asks question.
2. All students invited to respond.
3. Teacher and students observe student responses.
4. Teacher continues lesson building on student responses.

How many people disagree?
