Consistent class delivery. Ratings from 4.57 to 4.88.

At Scaler, the same topic could earn very different ratings across batches. Drona cue cards brought an authored class plan into the screen instructors already used to teach.

Scaler trains working professionals and school students for software, data science, data analytics and AI careers. Classes are taught live, and learners rate each class afterwards. That rating is the main quality signal.

My role

Led the project, problem framing and design. Engineering built the feature. The content team hand-authored every cue card.

Design of the live class screen: the teaching surface above, and a row of cue cards showing the current topic, an upcoming quiz and the topics still to come.

One course, many versions of the class

Instructors prepared from old Google Docs, slides, handwritten notes and chat messages. Each rebuilt a plan. The order, explanations and depth changed from instructor to instructor.

We first checked the learner LMS and the course content. Both were broadly sound. The part that varied between batches was the instructor's delivery. Scaler's benchmark was 4.5 out of 5, and repeated scores below it were treated seriously.

There was no single place to see what to cover, how to explain it or what was already done. When a live class ran out of time, remaining topics were often dropped without a record. The next class started from its own plan.

#1 Scattered files → cue cards inside the class screen

Presenter notes sit beside the live teaching surface. Each card shows the current topic, the sequence to follow and the explanation to give, without switching tabs.

The design moved the plan into the tool instructors already used. The class screen became the place to find both the material and the guidance for delivering it.

#2 Every instructor's own plan → one authored source of truth

The content team wrote one plan per class. Topics, order and important explanations were shared across batches. Instructors kept their own teaching style.

#3 Dropped topics → cards that move to the next class

When time ran out, remaining cards moved into the next scheduled class. Unfinished material stayed with the batch, even if the instructor changed.

Previously, an overrun could make a topic disappear between two class plans. Carrying the cards forward made the remaining work visible in the next session.

A more consistent learning experience

Average class ratings rose from 4.57 to 4.88, with gains across cohorts rather than only one module. Preparation became shorter, and unfinished topics had a place in the next class.

The project contributed to my promotion to Principal Product Designer.

Put the plan beside the teaching. Instructors no longer had to rebuild it from scattered files.

Standardise the content. Keep the sequence and explanations consistent while leaving teaching style with the instructor.

Carry unfinished work forward. A time overrun becomes visible work for the next class.
