Reflection: Developing a Conceptual Understanding Modeling the Atomic Structure - Section 4: Evaluation

 

I find it important that 100% of students master this portion of the unit because this is the foundation for future learning.  In the past I have found when students don’t understand the basics of the atom presented in this lesson, they will struggle with almost all other chemistry concepts.  For instance if students don’t understand that protons equal the atomic number, or that electrons have a negative charge, there is little hope that they will be able to understand the periodic table or comprehend the concept of bonding.  I often say that learning chemistry is like a house of cards; without a solid foundation there is very little change that a structure can be supported.  So it is best to take time early to make sure all students are up to speed, than lose them in a month.
