Sharing assignments in OpenClass
OpenClass is on a mission to improve & democratize education. Through our platform, educators can share assignments privately or with our entire community to improve accessibility of the best learning resources around the world.
Our assignments guide students through research-backed study sessions to reinforce learning. If this review is relevant to your teachings, feel free to add it to one of your classes!
Our format is simple and engaging: students are asked a retrieval question, then shown corrective feedback and a multiple-choice mastery question to assess their understanding of the material. Assignments adapt to unique student needs and continue to draw questions until a student has demonstrated mastery.

What are some challenges with part-of-speech tagging?
(Student response here)
One significant issue is ambiguity - words have multiple meanings. Thus, part-of-speech tagging is not a straight-forward task of just always assigning a given word its given tag. For instance, consider the following sentences:
- Mrs. Shaefer never got around to joining.
- All we gotta do is go around the corner.
- Chateau Petrus costs around 250.
'around' has a different meaning in all three example sentences and is a different part-of-speech in each.
In which of the following sentences is "Chinese" not an adjective (JJ)?
