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. Each requires 15 Stuff (Woody/Stony) and 1,000 ticks (16.67 secs) of work modified by the construction speed of the builder and the work to build factor and offset of the material.
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
Blackboards are technically unnecessary. Children can still reach growth tier 8 without blackboards attached to their school desk. 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.
