Which of the following supports the development of students' vocabulary in writing?

Engaging in word games and activities is particularly effective for developing students' vocabulary in writing. These interactive and often playful approaches encourage students to explore language in a dynamic way. Through games and activities, learners can encounter new words in context, utilize them in sentences, and understand their nuances. This experiential learning fosters deeper processing of vocabulary, making it more likely that students will incorporate these new words into their writing.

Additionally, such activities often involve collaboration or competition, which can boost motivation and make the learning experience more enjoyable. By interacting with peers, students can also share word meanings and usage, further reinforcing their vocabulary skills.

The alternative options do not support vocabulary development as effectively. For example, merely memorizing definitions can lead to superficial understanding without truly engaging with the words in practical contexts. Reading only non-fiction texts can limit the exposure to varied vocabulary that fiction often provides. Lastly, relying exclusively on a thesaurus may promote overuse of complex words without understanding their proper context, which can hinder effective communication in writing.
