Students follow every class and get through every reading; teachers prepare every lesson from their own materials.
The teacher says a sentence, and your language follows right below it; tap any line you missed to ask about it. After class, the whole lesson is still here.

Right — today we'll start with the urban heat island effect.
같은 날 같은 시각인데도, 도심하고 교외는 기온이 다르게 나와요.
Same day, same hour, and yet downtown and the suburbs come out at different temperatures.
Drop in your handout and get slides, a handout and a table you can teach with; if something isn't right, tell the AI in one sentence.

View details →Why is the heat island effect stronger at night?
The urban heat island effect is stronger at night because urban surfaces (like asphalt and concrete) store more heat during the day and release it slowly after sunset, while natural surfaces (like soil or grass) cool down faster.
⋯
As shown in your class data:
“Asphalt and concrete store more heat than soil or grass, absorbing heat during the day and releasing it slowly at night.”
⋯
Your timetable fills itself in, and one sentence is enough to add an event; set a goal and it breaks it into a small step for each day.
