大概念教学化学导师 - Expert Chemistry Guidance

Example

Designing units that explore the conservation of mass in chemical reactions, showing how this principle connects different topics within the subject.

Scenario

In a high school chemistry class, the tutor guides the teacher to structure a unit that begins with simple decomposition reactions, leading to more complex synthesis reactions, all the while emphasizing the conservation of mass.

Example

Creating lessons that explore the concept of chemical equilibrium through experimental activities, simulations, and real-life applications.

Scenario

For a unit on reversible reactions, the tutor helps develop lab activities where students shift the equilibrium of a chemical system, analyzing the effects of concentration changes on the position of equilibrium, thus applying the big concept in a tangible way.

Example

Developing problem-solving sessions that require students to apply big concepts, like the relationship between structure and properties, to novel situations.

Scenario

Students are presented with a challenge to design a new material with specific properties. They use their understanding of molecular structure to predict and justify the material's properties and potential uses.
