The listserver has been quiet lately; I'd like to start up
a discussion.
My question is: What sequence of topics do you typically
use? What is your rationale for the sequence that you
prefer?
I have listed my current sequence below, but it's not
carved in stone. Although it's a good sequence, I know
other teachers use very different sequences very
successfully. I'd like to know what they are!
For example, in my college prep chemistry classes, I like
the following sequence:
-Particulate Nature of Matter, Significant Figures
-Atomic Theory, including the modern model and electron
configurations
-Periodic Trends,
I like to do these all together in one continuous unit,
rather than revisiting atomic theory later in the year.
This year, to meet state testing requirements, I did
nuclear chemistry right after atomic theory.
-Chemical Bonding
-Formula Writing and Nomenclature
-Mole Based Problems (empirical formula, moles, gfm)
I find it's easier for student to remember ionic vs.
covalent nomenclature if they understand the difference in
bonding.
-Chemical Reactions
-Stoichiometry
Students have the prerequisite skills in writing formulas
and using moles before we start this unit.
-Gases and Solutions
-Kinetics and Equilibrium
-Acids and Bases
-Redox
This sequence builds on previous topics--we can talk about
Ksp and Ka, because of already developed skills.
