Question

collaboration online increases students motivation by
sparking an interest in a particular subject.
introducing them to others with different viewpoints.
holding students accountable to others.
demanding that students contribute to a group.

Explanation:

To determine the correct answer, we analyze each option:

• "Sparking an interest in a particular subject" is more related to content - based engagement rather than collaboration - specific motivation.
• "Introducing them to others with different viewpoints" is about exposure to diverse perspectives, not directly about motivation from collaboration.
• "Holding students accountable to others" in a collaborative online setting means that students feel responsible to their peers, which can increase their motivation to participate and perform well.
• "Demanding that students contribute to a group" has a more negative connotation and is not as effective in increasing motivation as the sense of accountability.

Answer:

holding students accountable to others.
