Asking in-class questions reflects the use of which assessment format?

The correct answer highlights how in-class questioning is fundamentally a form of communication. This assessment format allows teachers to engage students in dialogue, encouraging them to express their understanding and thoughts about the subject matter. Through questioning, educators can assess students' comprehension in real-time, facilitating immediate feedback and clarification of concepts.

Engaging in communication through questions not only helps gauge individual student performance but also fosters a dynamic learning environment where students can participate actively. This two-way interaction is crucial for developing critical thinking and discourse skills among students and is a key component in formative assessments.

In contrast, observation involves monitoring students' behaviors or performance without direct interaction, while written reports and products refer to assignments or projects that students complete independently, often after the learning process. Therefore, in-class questioning is clearly a communicative process, making it the most suitable choice for this assessment format.
