TulongGuro

Large classes and paper-based workloads make timely, personal feedback hard for Philippine public school teachers, and most learning management systems only record grades. TulongGuro drafts rubric-based feedback on Grade 6 English work so the teacher can spend their time reviewing it instead of writing it from scratch.

• AI-assisted checking: the model reads handwritten or typed submissions and drafts rubric-aligned scores, strengths, areas for growth and next steps.
• Human-in-the-loop review: teachers validate and can edit every AI draft, and releasing grades to students is a separate step.
• Separate Teacher, Student and Admin interfaces; school admins manage sections, course shells and student rosters.
• Progress dashboards that track mastery of curriculum competencies across activities.
• Badges that students earn from performance and milestones.
• Delivered as a progressive web app, so it runs on desktop and phones without an app store.

The AI drafts; the teacher decides

Validation and release are separate acts, so a grade reaches a learner only after the teacher has reviewed the set and published it. The thesis abstract reports that raw AI drafts matched teacher-set performance bands in only about a quarter of cases, which is why the system is positioned as decision support and not as an automatic grader.

Images are prepared on the server before the model sees them

Photographed or uploaded work is optimised server-side, then read and scored against the rubric in a single model call.

A fallback model keeps checking available

Checking rotates between a primary and a fallback Gemini Flash model, so a class is read to one standard whichever one answers.

I co-developed TulongGuro in a four-member thesis team: a learning management system in which a Gemini vision-language model reads typed or handwritten student work against the teacher's rubric and drafts scores and feedback. I kept teachers in control with a human-in-the-loop review flow, where every AI draft is validated and editable and releasing grades to students is a separate step, and delivered separate Teacher, Student and Admin interfaces as a progressive web app, with progress dashboards for curriculum competencies and student badges.
