Reflection: Accountability Differentiated Exploration of Collision Theory - Section 4: Reaction Rate Review


One of the nice things about using jigsaws in the classroom is that you can cover more material faster.  However, it is tough when all the material is essential for each student to understand and there is not time for an all class check for understanding. 

As the student work in this section illustrates, there were still many misconceptions regarding the factors that speed up reactions.  However, we took our quiz the following day and didn't do very well, prompting a return to the topic.  Had I collected and checked the review with the expectations of an extra day before the quiz, I would have been armed with the data to pro-actively re-instruct, instead of using the quiz scores to realize that many students still were confusing parts of the collision theory.

In hindsight, I should have had all students perform all the parts of the Gizmo, and complete the review for homework.  Then we could have gone over it the next day, performed some chemical demonstrations and completely solidified student understanding, and then assessed more formally.

Differentiated Exploration of Collision Theory

Unit 5: Kinetics and Equilibrium
Lesson 6 of 17

Objective: SWBAT explain how adding a catalyst or manipulating the temperature, surface area or concentration affects the rate of reaction according to the Collision Theory of Chemical Reactions.

Big Idea: Differentiated instruction following inquiry fills in content gaps while keeping students engaged in learning about chemical reactions.
