The Book That Broke The Mold

The mold …

We teach general chemistry as ifwe first must carefully build the foundation for our students …

…so that later down the road our students get to take what they know and examine the larger exciting and sometimes troubling issues in our discipline and in our world.

General chemistry courses aim to provide a foundation for future courses.

The act of “covering” a large amount of content may create the very conditions under which students find it difficult to learn this content.

Evidence suggests that disjointed or piecemeal facts about any field, including chemistry, are unlikely to provide deep conceptual understanding.

interconnected

time‐tested

2. They demonstrate how content & context are two sides of the learning coin.

Unlike humans, chimpanzees don’t argue with each other about whether climate is changing. They just attempt to adapt to the ever‐changing world, which can affect their way of life including their access to food, water, and habitat, …

Unlike humans, chimpanzees don’t argue with each other about whether climate is changing. They just attempt to adapt to the ever‐changing world, which can affect their way of life including their access to food, water, and habitat, …

Carbon dioxide isn’t the only player, as we will see in this chapter. We also will talk about other gases, such as methane and water vapor, and how they contribute to the greenhouse effect.

Having completed this chapter, you should be able to:

What’s wrong with this picture?

Have students answer this question in groups.


Possible responses:

• The air molecules should be in motion and colliding.

• The representations of N2 and O2 molecules have problems, i.e., the atoms are not red and blue … and the molecule is not a dumbbell.

• The spaces between the molecules are not drawn to scale.

What’s right with this picture?

Have students answer this question in groups.


Possible responses:

• relative amounts of N2 (78%) and O2 (21%).

• N2 and O2 are represented as diatomic molecules.

• The spacing of these molecules shows that they aren’t touching in the gas phase.

• AND it shows “other” …
