Reflection: Complex Tasks How Can You Make A Sundial? - Section 3: PCRR: Present, Critique, Reflect, Refine


I wanted to add rigor to my student's learning experience so I collaborated with my colleague at BetterLesson, David Kujawski, to glean some ideas. In this lesson, students were making a model of a sundial. This high level, complex task incorporates multiple science skills like asking questions, developing models, understanding patterns and cause & effect relationships, but..... I wanted even more. I wanted my students to develop their communication, critique, and reflection skills so I shared this model with them and facilitated the discussion as my students incorporated the PCRR model (present, critique, reflect, refine) into the lesson.

From using the PCRR model, my students communication skills grew. They learned to present their model to their peers in a non-threatening environment, spoke respectfully to each other when critiquing, and thoughtfully reflected with their partner to address any changes to their model. I have worked to cultivate a classroom environment of respect and rapport and it was truly evident during this lesson as students worked collaboratively with peers to present, critique, reflect, and refine their model of a sundial. Success!

How Can You Make A Sundial?

Unit 6: Earth, Sun, and Moon
Lesson 6 of 12

Objective: SWBAT make a model to show the effect of Earth's movements.

Big Idea: How did man first learn to measure time? Investigate to find out. If the sun is shining, you don't need a watch because the Sun makes an excellent clock.
