Reflection: Rigor Ionic Bonding - Section 4: Application


Some students quickly showed mastery for the concept of balancing charge, while some students really wrestled with the concept. I believe that this is a skill that takes time for many students, but I also recognize that some students are clearly ready to move on. this is where differentiation becomes very important.

I have structured this unit by letting students know that in order to get the highest grade they need to master polyatomic ions and not just monatomic ions. I am careful how I craft this message. I only tell a student this when they are ready to hear it. If they are not showing mastery of the learning target for this day, then I keep helping them with it and encouraging them along. However, if a student is not being challenged by the material, I want them to be.

Our school is very attuned to the ideas found in Carol Dweck's book Growth Mindset. One of the ideas in this book is that people can get smarter by exercising their brains. For this reason, I want students to experience challenge in my classroom every single day. When I have a clear sense of what I am leaving out of a lesson, and can plan an extension activity for that material, I honor all students. For students who need more time, they get it. For students who need more challenge, they get it too. I used to have students ask me fairly frequently "Now what do I do?" and it would break my heart. Now, I get to celebrate a student's higher aptitude by helping them to reach higher.

Ionic Bonding

Unit 4: Compounds
Lesson 4 of 8

Objective: Students will be able to model how ionic compounds form and to name them.

Big Idea: Atoms become ions by losing or gaining electrons to achieve a full valence shell. These ions then bond with other ions to balance their charges and form compounds.
