Which of the following tools is effective for evaluating digital media literacy in students?

Using a Venn diagram to compare written conventions in media is effective for evaluating digital media literacy in students because it promotes critical thinking and analytical skills. This tool allows students to visually organize and compare different types of media, highlighting similarities and differences in their conventions, such as tone, style, structure, and intended audience. By engaging with a Venn diagram, students learn to discern how various forms of media communicate messages, which is a central aspect of digital media literacy.

In contrast, creating a sales pitch focuses more on persuasive techniques rather than evaluating comprehension of media conventions. Practicing how to write an email may help with general communication skills but does not specifically assess students' understanding of media literacy. Conducting a survey on media usage can provide data on student interactions with media but does not directly evaluate their ability to analyze or interpret media content in a critical way. Thus, the use of a Venn diagram specifically targets the evaluation of students' understanding of digital media conventions, making it the most suitable choice for this purpose.
