^What is wrong with “as” ?? I thought the error was “far different” … shouldn’t it be “far differently” ??
The correct conjunction is “when” not “as”.
“when”= “those times when”
“as”=“at the same time as”
The phrase “promotes learning far different from that which results” means “promotes learning far different from the learning that results”.Thus in this phrase, the word “different” modifies “learning” not “promotes”. “Learning” is a simple gerund functioning as a noun. To modify a noun, you need an adjective (“different”), not an adverb (“differently”).
