ScoatClass — Scoat

Project Overview

ScoatClass is a web-based learning and class management platform (LMS) designed to consolidate routine classroom administration, teaching materials, and student activity into a single, cohesive workflow.

Many educational teams rely on a patchwork of disconnected tools: chat apps for distribution, cloud drives for files, spreadsheets for rosters, and ad-hoc forms for quizzes. ScoatClass centralizes these requirements into an integrated portal tailored for direct instructor-student interaction.

The Challenge

Off-the-shelf institutional LMS solutions (such as enterprise Moodle or Canvas setups) are frequently over-engineered for small-to-medium educational institutions, coaching classes, or independent tutoring cohorts. They carry heavy server overhead, complex administrative hierarchies, and steep learning curves.

Key challenges identified:

Fragmented Communication: Learning materials get buried in group chats or disorganized shared drives.
Attendance & Submission Tracking: Instructors spend excessive time tallying submissions and manually calculating participation metrics.
Resource Organization: Course content lacked hierarchical structuring (modules, lessons, supplementary attachments).
Access Friction: Students struggled with cumbersome login flows and disjointed interfaces on mobile devices.

Core Features & Functional Workflows

ScoatClass was built around simplicity, speed, and clear operational boundaries:

Class & Roster Management

Teachers can create classes, generate unique enrollment codes, track active rosters, and manage student lifecycle states without IT assistance.

Modular Course Builder

Structure curriculum into sequential modules, reading handouts, embedded references, and homework deliverables with clear due dates.

Student Assignment Portal

Clean interface for students to view deadlines, submit files or text entries, and receive timely feedback and grade marks.

Activity Logs & Progress

Instructors receive consolidated views of who has accessed materials, completed tasks, or requires proactive academic intervention.

Technical Architecture

The platform is architected around a modular MVC pattern powered by PHP and a relational MySQL database. This ensures high portability, low hosting requirements, and rapid server-side rendering.

Storage Engine Secured Uploads & File Handlers

Data Model & Relationship Strategy

The database schema enforces strict referential integrity with cascading updates and soft deletes where auditability is essential. Key entities include:

users — Role-based authorization flags (Admin, Teacher, Student).
classrooms — Core tenant container with enrollment tokens and terms.
enrollments — Junction table tracking student registration status and join dates.
modules & lessons — Hierarchical content tree with sequential sorting order.
assignments & submissions — Task criteria, timestamped payload logs, and grading status.

Security & Data Integrity

Because an LMS handles student records and academic grades, security practices were baked in from inception:

Parameterized SQL Queries: All database interactions utilize PDO with strictly parameterized statements to neutralize SQL injection vectors.

Strict Role-Based Access Control (RBAC): Every controller route validates role permissions prior to executing actions, preventing horizontal privilege escalation.

File Upload Sanitization: Uploaded materials undergo mime-type inspection, filename randomization, and isolation outside the webroot to prevent malicious script execution.

Context-Aware Output Escaping: All student-submitted data and comments undergo HTML escaping upon rendering to eliminate stored Cross-Site Scripting (XSS).

Current Status & Roadmap

ScoatClass is currently in an In Development state with core administrative, classroom enrollment, and assignment submission flows verified.

Next implementation milestones:

Interactive real-time notifications for due dates and grade releases.
Integration with the Scoat CBT module for seamless in-platform testing.
Export utilities for grade transcripts in standardized CSV/Excel formats.
