The same classroom used with tutors is ready here: admin-enabled workspaces, active-tab awareness, and a student who can see and use the shared lesson surfaces.

Hi, I am Paulina. I remember many chemistry formulas, but I want the equations to make physical sense. Draw the particles with me, then give me a calculation I cannot solve by memory alone.

Who you are teaching

Meet Paulina

Paulina is beginning university chemistry after doing well through memorization at school. She can identify familiar equations, yet coefficients, moles, and limiting reagents still feel like separate tricks. Particle diagrams, dimensional analysis, and prediction before calculation help her connect the symbols to what is physically happening.

Personality: Focused, quietly competitive, patient with calculation, and visibly relieved when symbols connect to a physical picture.

The useful difficulty

What your explanation has to overcome

Starting gaps

  • Mole as a counting unit
  • Coefficient versus subscript
  • Limiting-reagent logic

Plausible misconceptions

  • Changing a coefficient changes the identity of a substance
  • The reactant with the smallest mass must run out first

Evidence of learning

What progress should look like

1

Connect equations to particle counts

2

Use dimensional analysis consistently

3

Identify a limiting reagent with reasons
