The blackboard is a furniture item added by the Biotech DLC that improves the rate a child learns at a school desk.
Acquisition
Blackboards can be constructed once the Complex furniture research project has been completed. They require 15 Stuff (Woody/Stony) and 1,000 ticks (16.67 secs) of work.
Summary
When connected to a school desk, each blackboard increases a student's Learning rate from Lesson Learning by 20%. This effect can stack up to three times per desk. A blackboard can connect to multiple desks. It does not matter which way the blackboard is facing.
It is unknown if blackboards increase skill XP gain from learning with an adult.[Verify]
Analysis
If you have a comms console and a means of going outside, then blackboards are technically unnecessary. Children can still reach growth tier 8 without blackboards attached to their school desk, so long as the other learning types are available. However, these buildings still increase average growth points. Therefore, blackboards will make up for extended periods of non-Learning, such as when resting from disease. And, because they are so cheap, you might as well build them.
