Questioning and Discussion in Science
“The 5 Practices”
Focus on student’s use of:
Experimentation
Data representation, analysis and interpretation
Explanation of patterns and phenomenon
Increasing cognitive demand of tasks:
Minimize prescriptive directions
Provide complex data that students must interpret
Give students an audience
Re-sequence lessons – let students explore before teaching
“The 5 Practices”
After developing a rigorous task:
1. Anticipate how students will respond
2. Monitor what students do as they work
3. Select students to present their work
4. Sequence the presenting students in a meaningful order
5. Connect student responses to science content.
Picture Prompt
Show the class a complex diagram/image.
Each person must explain one thing about the image.
Thinkathon
Each group begins at a station with a chart paper containing a diagram or question.
Students explain the diagram/answer the question.
Groups rotate to the next diagram. They agree or disagree with previous answers by making a “” or “X” and then write their own answer.
After groups finish rotating, they present their diagram/question to the clas..
If you hold a fire to steel wool, it will burn and change color. After it changes color, it will not burn anymore. Why? Explain what is happening.
Layered-Cake Discussion
Students are broken into groups
Groups all work on the same task
After a set amount of time, groups share out and have a class discussion
A student made a copper bracelet by hammering a small copper bar into the desired shape. The bracelet has a mass of 30.1 grams and was at a temperature of 21°C in the classroom. After the student wore the bracelet, the bracelet reached a temperature of 33°C. Later, the student removed the bracelet and placed it on a desk at home, where it cooled from 33°C to 19°C. The specific heat capacity of copper is 0.385 J/g•K.
Explain, in terms of heat flow, the change in the temperature of the bracelet when the student wore the bracelet.
