The Concept of Ratio in Math and Chemistry
The goal of this workshop is to help students to become skillful in transferring knowledge from arithmetic (ratio) into chemistry (units).
Workshops are one way of tutoring. In some workshops, facilitators provide resources for students.
In some cases, facilitators train students in the art of organizing and using appropriate learning resources for different assignments.
EXAMPLE:
A Workshop on Operations with Units in Chemistry
The goal is: Transferring knowledge and skills from math to chemistry.
Skillful facilitators use at least two textbooks in such workshops - one arithmetic textbook and one chemistry textbook.
One possible scenario:
Ask the students to locate the formula for morality in the textbook.
Ask one of the students to write the formula on the board.
Now, let's say that we have 3 molls per 2 liters.
Ask the students to discuss the word "per" from two points of view - math and chemistry.
The goal of the facilitator is to lead students to deep understanding of the difference between division.
What happened if we divide the number of moles (3) by the number of liters (2)?
What is the meaning of 1.5 moles per liter (1.5 moles per ONE liter.
Now use the concept of unit ratios to practice conversion.
Continue with dimensional analysis.
Lead students to create materials for the finals. For example,
let the student rearrange the classroom notes into something meaningful to them.
You teach the art of learning -- the concepts may change, but the main principals of the art of transferring knowledge are very important.
Ask the student to write a chemical equation.
Ask the student to name each symbol using the textbook or notes from the classroom.
Ask the student to write the unit for each symbol.
Now let the student substitute the symbols in the equation with units.
Ask the student to simplify.
Do we have an identity?
