Home summary model with self-study default emphasis

DEC-0012 - Home summary model with self-study default emphasis

Superseded by DEC-0037 (2026-02-18). This record is kept as historical baseline for Stage C.

Context

Need to define Home behavior at platform level before deep UI/feature details.

Decision

Home role:

• Home is a summary page at system level.
• Home summarizes user activity across major learning areas.

Data visibility:

• Home includes both self-study and course information.
• Course statistics are shown only when user has course participation.
• If user has no course participation, course statistics are hidden.

Default emphasis:

• Home default emphasis is self-study and practice statistics.
• Home does not remember preferred lane (course/self-study) for first highlight at this stage.

Navigation role:

• Home includes direct navigation to both:
  • course-related pages,
  • exercise bank/self-study pages.
• Home includes quick links to each program landing page.

No-history behavior:

• For users with no history, Home still shows statistics in empty-state form.
• Home must provide clear call-to-action in empty-state.
• Default first call-to-action for brand-new users: “Kham pha chuong trinh”.

Community stimulation:

• Home post-login includes community stimulation sections (for example: Learn Mode, weekly challenge).
• Community sections are shown immediately, including for brand-new users.

Suggestion behavior:

• If user has no goal yet, suggest all available programs.
• If user has goal, prioritize suggestions for related courses and exercises in target program.
• Home can also suggest exercises that many users practiced in recent period.
• “Recent period” for popular exercises is 14 days.

Depth boundary:

• Home remains summary-only.
• Detailed insights and deep breakdown must be viewed in each dedicated management page.

Rationale

Keep Home useful for all users while preserving self-study-first positioning and avoiding overload from deep details on one page.
