Hi, I'm Rohit Sharma.
I study what live classrooms reveal about learning, and build the tools that capture it.
Computing education research, live classroom polling and learning analytics, with the systems to match.
Research focus
What live classrooms can tell us
Every live poll leaves a record. My work reads that record carefully, to see what questions do in a lecture, how good they are as measurements, and what learners reveal beyond right or wrong.
Reading polls in context
Interpreting each live poll against the lecture it came from, to see what it actually does in the class.
Polls as measurements
Treating classroom questions as a measurement instrument: how reliable they are, and where answer bias creeps in.
Signals beyond right or wrong
Using response timing and how a class divides to understand learners, even before an answer key exists.

Characterizing Questioning Patterns and Student Engagement Through Contextual Analysis of Real-Time Classroom Interactions
Key finding The answer to 89% of polls is locatable in the lecture; a poll's response follows its function, not its wording.
arXiv:2609.38959 · Sep 2026 · cs.HC, cs.CY
An Audit of Measurement Quality and Answer Bias in a Large Classroom-Poll Corpus
Key finding 77% of students lean True, so False-keyed items run about thirteen points harder.

Insights on Student Learning from Live Classroom Polls: More Than Right or Wrong
Key finding A learner's response order is a stable signature (split-half reliability 0.92), unrelated to correctness.
