2. National Curriculum (CDC) & Textbook Management

The foundation of Shikshak is Nepal's Curriculum Development Centre (CDC - पाठ्यक्रम विकास केन्द्र) national syllabus. Every lesson plan, exam paper, and worksheet generated is tied directly to the learning outcomes mandated for that grade and subject.

1. Supported Grades & Subjects

Shikshak includes pre-loaded curriculum data aligned with the latest CDC 2081 / 2080 BS syllabus:

• Basic Education (Grades 1 to 5):
• नेपाली (Nepali), English, गणित (Mathematics), हाम्रो सेरोफेरो (Our Surroundings / Social Studies & Science).
• Basic Education (Grades 6 to 8 - BLE/SEE Preparation Foundation):
• विज्ञान तथा प्रविधि (Science & Technology), गणित (Mathematics), नेपाली (Nepali), English, सामाजिक अध्ययन तथा मानव मूल्य शिक्षा (Social Studies & Human Values).
• Secondary Education (Grades 9 & 10 - SEE Curriculum):
• विज्ञान तथा प्रविधि (Compulsory Science & Technology)
• अनिवार्य गणित (Compulsory Mathematics)
• ऐच्छिक गणित (Optional Mathematics)
• अनिवार्य नेपाली (Compulsory Nepali)
• Compulsory English
• सामाजिक अध्ययन (Social Studies)
• Higher Secondary Education (Grades 11 & 12 - NEB Curriculum):
• Physics, Chemistry, Biology, Mathematics, English, नेपाली (Nepali), Social Studies & Life Skills.

2. Browsing Pre-Loaded Textbooks & Digital Flipbooks

To view available curriculum units, chapters, and digital flipbooks:

• Units Count: Number of units or chapters in the textbook.
• Language / Medium: English or नेपाली.
• Verified (प्रमाणित): When an educator has verified the chapter titles against the physical textbook, a green Verified (प्रमाणित) badge appears next to the language tag. Books awaiting human chapter verification display no badge until signed off.

• Grade (कक्षा): Grades 1 through 12.
• Subject (विषय): CDC Compulsory, Optional, or Technical subjects.
• Medium / Language (माध्यम / भाषा): Filter instantly by Nepali Medium (नेपाली माध्यम), English Medium (अंग्रेजी माध्यम), or Local/Mother Tongue (स्थानीय/मातृभाषा).
• Publisher (प्रकाशक): CDC (पाठ्यक्रम विकास केन्द्र) or NEB (राष्ट्रिय परीक्षा बोर्ड).

My Textbooks

If you picked specific textbooks during signup (or later in Settings > Teaching Profile), the Textbooks page opens on My Textbooks — just the books you actually teach from — instead of the full national catalog. A toggle at the top switches to All Textbooks any time you want to browse or add more. Nobody without a saved selection (including a guest who hasn't signed up) sees anything different — the page stays the full public catalog for them, exactly as before.

Human Verification of Chapters (प्रमाणीकरण)

Textbooks in the national catalog are extracted directly from official CDC/NEB PDF textbooks. Once an educator reviews the chapter list against the physical textbook and confirms or saves any corrections in the Edit Syllabus tab, the textbook is marked Verified (प्रमाणित) with a green checkmark badge next to its language tag. Until verified, books display no badge so that educators know the chapter titles remain pending human sign-off.

2b. "Source: textbook page 37–40" on your lesson plan

Some lesson plans end with a small line like:

It means Shikshak read those pages of your textbook and wrote the plan from what

they actually say — the book's own terms, its worked examples, its order —

rather than from general knowledge about a chapter with that name.

Turn to those pages. They are the pages the plan came from, and they are the

fastest way to check it. Shikshak refuses a plan that names a page it was not

given, so the numbers are real page numbers, not a guess. Where the number

printed in your book differs from its position in the PDF, the line shows the

printed one.

No Source line is normal. It means that textbook has not been read into

Shikshak yet. The plan is still a complete, usable lesson plan, built the way

every Shikshak plan was built before this feature existed: from the unit title

and the CDC learning outcomes. It just has not been checked against the book.

There is nothing to switch on and nothing to buy. A textbook is read once, and

from then on every teacher using that same book gets grounded plans from it.

3. Uploading a New or Custom Textbook (/curriculum/new)

If your school uses a specialized textbook, local curriculum (स्थानीय पाठ्यक्रम), or a newly revised CDC edition that is not yet in the catalog, you can upload it:

Who Can See a Book You Upload

• Private by default. A textbook you upload is visible only to you. Other teachers cannot find it in the catalog, open its pages, or generate from it.
• Make it public if you want. After the book is confirmed, open its page and use "Make public". Every teacher can then read it and generate lesson plans, question papers and slides from it. Use "Make private" to take it back at any time. Documents others already made stay with them.
• The CDC catalog books are always public. Only books you uploaded can be made private or public.
• Uploading a file someone else already uploaded gives you your own private copy. You never receive another teacher's private book.

Why Shikshak Handles Nepali Textbooks Better Than Other Tools:

Many Nepali textbook PDFs are encoded using traditional fonts like Preeti or Kantipur. Standard PDF readers and AI tools see these as scrambled Latin letters (e.g. ljifo;"rL instead of विषयसूची).

Shikshak uses advanced vision rendering that reads the actual glyphs on the page, producing pure, clean Devanagari Unicode every time.

4. Reviewing & Editing Chapters & Sub-Chapters Before Confirmation

After an uploaded textbook is processed, you are presented with the Chapter & Sub-Chapter Editor:

• Edit Titles: Correct any typos or spelling variations in Devanagari Unicode.
• Multi-Level TOC (Sub-Chapters / Topics): For chapters with sub-sections or multiple periods, click "+ Add Sub-Chapter" to list sub-chapters (e.g. *१.१ चाल र गतिशीलता*, *१.२ न्यूटनका नियमहरू*).
• Cross-Tool Generator Alignment: Sub-chapters configured here appear directly across all teaching tools — Lesson Plan, Presentation Slides, Question Paper, Practice Worksheet, Remedial Plan, TLM Guide, and Homework Planner — letting teachers select an exact 45-minute lesson slice or topic in one click.
• Reorder Chapters: Use the Up and Down arrow buttons to ensure the sequence matches your syllabus.
• Add Missing Units: Click "+ Add New Chapter" to insert any supplementary or practical units.
• Remove Non-Chapters: Delete any front-matter sections (preface, editorial credits, national anthem) captured during extraction.
• Empty TOC & Manual Chapter Entry Fallback: If your PDF is a scan without a readable Table of Contents, or if automatic detection finds no units, Shikshak automatically transitions the book into a draft state with an empty Table of Contents. An on-screen prompt guides you (*"Table of contents could not be automatically detected from this PDF. Please enter the chapters and sub-chapters manually using your textbook and confirm."*). Click "+ Add New Chapter" and "+ Add Sub-Chapter" to enter your curriculum units directly from your printed textbook.
• Confirm & Publish: Once confirmed, the textbook is cached and instantly available for you and your colleagues to generate lesson plans and tests from!

5. 1-Click Teaching Material Generators for Each Unit (/curriculum/[id])

Inside the interactive textbook reader (/curriculum/[id]), teachers have access to 1-click generation studios tied directly to each specific unit and its official CDC competencies:

Clean 3-Column Book Overview:

The top header provides a clean 3-column workspace layout: (1) authentic textbook cover thumbnail, (2) comprehensive book and publisher details with grade/edition badges, and (3) vertically stacked workspace action buttons: Syllabus & AI Studio, Edit Syllabus, and Digital Textbook.

Sub-Chapter Scoping Pills:

When a chapter contains sub-chapters or multi-period topics, clickable pills appear right above the generator cards. Selecting a sub-chapter dynamically configures all 8 generator buttons (e.g., Lesson Plan, Slides, Question Paper) to immediately target that specific sub-chapter.

Available Tools by Subscription Tier:

• Free Plan (`Free`): 4-Step Daily Lesson Plan, Specification Grid Exam Paper (Set A).
• Plus Plan (`⭐ Plus`): Interactive Presentation Slides, Homework & Assignment Planner, Low-Cost TLM Making Guide, Remedial Teaching & Diagnostic Plan.
• Pro Plan (`✨ Pro`, Coming Soon): Student Practice Worksheet, Multi-Week Chapter Plan.

More tools (CAS Rubrics, Annual Plan, Practical Lab Manual, Friday ECA Planner, and others) are in active development and are not shown here yet -- they were previously listed by tier. See /pricing for what is live and what is Coming Soon.

Smart Filter Controls:

• All (8): Browse all pedagogical tools aligned with the active unit.

6. Digital Textbook Flipbook Reader & Copyright Protection

Inside any curriculum page (/curriculum/[id]), teachers can launch the realistic interactive reader by clicking the Digital Textbook (Flipbook) (नेपालीमा: डिजिटल पाठ्यपुस्तक (Flipbook)) button in the top action panel:

• Instant Recognition & Uniform Naming: Clearly labeled as Digital Textbook (Flipbook) / डिजिटल पाठ्यपुस्तक (Flipbook) across all curriculum catalog views, workspace headers, and loading screens.
• Cloud-Streamed Interactive Reader: Official CDC and NEB textbooks (such as Grade 9 Science & Technology and Grade 10 Mathematics) stream high-fidelity page images directly from secure cloud storage with intelligent table-of-contents chapter jumps.
• Authentic Page-Turn Experience: Side-by-side 2-page spread animation on desktop and tablet displays with smooth page-curl physics and realistic paper-friction turn audio, adapting automatically to single-page portrait reading on smartphones.
• Comprehensive Controls: Zoom in/out, fullscreen toggle, sound mute/unmute, direct page number input jump, and chapter navigation drawer.
• Fast Preloading & Graceful Feedback: Pages preload automatically as you read, eliminating blank pages or lag during classroom presentations. If a specific page or newly cataloged book is still being prepared by CDC, teachers receive a clear localized status message while the full syllabus remains active in the AI Studio.
• Copyright & Content Protection: To protect publisher copyright and textbook licensing (CDC & NEB), direct file downloads and right-click copying are strictly disabled across all flipbook viewing modes. Teachers and students can view the full curriculum text directly within Shikshak securely.
• Mobile Smartphone Optimization: On mobile smartphone screens (360px–430px), the reader workspace cards and chapter badges wrap cleanly with zero horizontal layout shift. In flipbook mode, the top control bar condenses action buttons to give maximum room to the book title, while bottom page controls adapt to touch-friendly sizes.
