详情介绍:
PressPrimer Assignment is a professional assignment submission and grading plugin that gives WordPress educators everything they need to collect student work, provide meaningful feedback, and track grades, all without juggling email attachments, shared drives, or clunky LMS add-ons.
Students get a clean, focused submission experience. Teachers get a centralized grading dashboard with a built-in document viewer, rich text feedback, and inline annotations available via the School addon. And you keep full control of your data on your own WordPress site.
This is a genuinely free plugin. Unlimited assignments, unlimited submissions, full grading tools, LMS integration, and email notifications are all included at no cost. We earn upgrades by building specialized features worth paying for — group management, rubric grading, AI-assisted grading and proofreading, document annotations, anonymous grading, AI content and plagiarism detection, xAPI / LRS support, automated data retention, audit logging, and white-label branding — not by crippling what you get for free.

Why PressPrimer Assignment?
Built-in assignment tools in WordPress LMS plugins are often afterthoughts, limited to basic file uploads with no real grading workflow, limited feedback options, and dated interfaces. Dedicated assignment platforms charge monthly fees with per-student pricing that gets expensive fast.
PressPrimer Assignment delivers a focused, polished assignment workflow with the features educators actually need:
- Flexible Submission Types – Accept file uploads, rich text submissions, or let students choose. Support for PDF, DOCX, TXT, RTF, ODT, and image files out of the box.
- Grade Without Leaving WordPress – A dedicated grading queue with a side-by-side interface: the student's document renders on the left while you score and write feedback on the right. Built-in viewers for PDF, Word documents, images, and text files mean you never have to download, open, and track files on your desktop.
- Native LMS Integration – Works with LearnDash, Tutor LMS, LifterLMS, and LearnPress. Assignments appear in lessons, passing grades trigger lesson completion, and instructor roles are mapped automatically.
- Secure File Handling – Six-layer file validation and permission-based file serving. Student files are never directly accessible via URL.
- Customizable Email Notifications – Automatic emails for submission confirmation, grade release, and new submission alerts. Fully customizable templates with token placeholders.
- Three Professional Themes – Default, Modern, and Minimal themes that match the PressPrimer Quiz visual style.
- Unlimited assignments and submissions
- Configurable maximum points and passing score
- Three submission types: file upload, text/rich text, or student's choice
- Configurable file types, file size limits, and multiple files per submission
- Duplicate any assignment to copy its settings
- Drag-and-drop file upload with progress indicators

- Built-in viewers render PDF, DOCX, images, and text files directly in WordPress; no downloading required
- Automatic text extraction from PDF, DOCX, ODT, RTF, and TXT files with quality scoring
- Rich text feedback editor with bold, italic, lists, and links — feedback is rendered with its formatting on the student view, not as plain text
- Submissions list filterable by score range, feedback presence, and submission date range
- Grading guidelines reference panel pulled from the assignment
- Submission confirmation, grade notification, and new submission alert emails
- Customizable subject and body templates per email type
- Token placeholders: student name, assignment title, score, feedback URL, and more
- Dashboard with submission statistics, activity chart, and recent submissions
- Reports page with filterable submission data
- Six-layer file upload validation (extension whitelist, MIME verification, double-extension blocking, dangerous file rejection)

- Capability-based access control (teachers see only their own assignments)
- WordPress Privacy API integration (Tools > Export/Erase Personal Data)

- Groups & Assignments – Organize students into groups, distribute assignments with per-group due dates, and track completion progress

- Rubric Builder – Create analytic rubrics with criteria and performance levels, attach them to assignments for structured grading with automatic score calculation and per-criterion feedback
- Per-Criteria Report – See where students are struggling at the rubric-criterion level
- Teacher Role – Teachers manage their own groups and grade only their students' submissions, while admins retain full access to all data
- Data Retention & Cleanup – Automatically prune old submission files and orphaned data
- Inline Document Annotations – Mark up PDFs, images, and text submissions directly in the grading interface with highlights, underline, strikethrough, freehand drawing, and comments.
- AI-Assisted Grading – Generate suggested scores and feedback for submissions using OpenAI or Anthropic. Rubric-aware: returns per-criterion scores when a rubric is attached.
- AI Proofreading – Detect spelling and grammar issues in student submissions with one-click insertion of notes into feedback. Configurable locale for regional spelling variants.
- xAPI / LRS Integration – Send Experience API statements to your Learning Record Store. Built-in queueing system ensures reliable delivery.
- AI Content & Plagiarism Detection – Run submitted text through Winston AI, GPTZero, or Originality.ai to surface AI-generated content and plagiarism scores. Auto-check on submission or run manually. Provider-aware grading panel shows scores and interpretation.
- Plagiarism Report – Cohort-wide report with AI-likelihood and originality-score distributions, stat cards, a per-provider confidence breakdown, and a paginated flagged-submissions table with colour-coded scores and tooltips explaining exactly why each row was flagged.
- Anonymous Grading – Per-assignment toggle that masks student identity throughout the grading window so grades aren't biased by who wrote the work. Identity stays hidden until submissions have been graded and returned.

Audit Trail report on the Reports page surfaces filterable events with object links and a search box.

常见问题:
Is this really free, or is it a limited trial?
It's genuinely free and not locked down. PressPrimer Assignment includes unlimited assignments, unlimited submissions, full grading tools, LMS integrations, email notifications, and three professional themes in the free version. We believe in earning upgrades by offering genuinely valuable features, not by crippling the free experience.
Does this work with LearnDash?
Yes. PressPrimer Assignment integrates natively with LearnDash. Attach assignments to lessons or topics, and passing grades can automatically trigger lesson completion. LearnDash Group Leaders receive teacher-level permissions to create assignments and grade submissions. The integration activates automatically when LearnDash is detected.
Does this work with Tutor LMS?
Yes. Assignments integrate with Tutor LMS lessons via the editor sidebar and course builder. Passing grades can auto-complete lessons, and course completion triggers when all lessons are done. Tutor LMS Instructors receive teacher-level permissions automatically.
Can I use this without an LMS plugin?
Absolutely. PressPrimer Assignment works as a standalone plugin. Use the [pressprimer_assignment] shortcode to embed assignments on any page or post. The LMS integrations are a bonus that enable automatically when an LMS is detected—they don't restrict standalone use.
Does this work with PressPrimer Quiz?
Yes. Both plugins are part of the PressPrimer suite and are designed to work together. When both are active, they share the Groups infrastructure and Teacher role for a unified experience. Each plugin also works independently.
What file types can students upload?
By default: PDF, DOCX, TXT, RTF, ODT, JPG, JPEG, PNG, and GIF. Administrators can configure allowed file types per assignment. All uploads go through six layers of security validation including MIME type verification and dangerous file blocking.
Can students submit text instead of files?
Yes. Each assignment can be configured to accept file uploads, text/rich text submissions, or let the student choose. Text submissions use a TinyMCE editor with live word and character counts, auto-save drafts, and a 50,000-character limit.
How does the grading interface work?
The grading interface uses a side-by-side layout. The student's submitted document renders directly in the left panel. PDF, DOCX, images, and text files all display without downloading. The right panel has fields for score, pass/fail status, and rich text feedback, plus a reference panel showing the assignment's grading guidelines.
Can I customize the email notifications?
Yes. Each email type (submission confirmation, grade notification, admin alert) has its own customizable subject and body template. Templates support token placeholders for dynamic content like student name, assignment title, score, and feedback. You can also set a custom from name, from email, and upload a logo for the email header.
Can graders annotate student documents directly?
Yes, with the School addon. Inline document annotations let you highlight, underline, strikethrough, freehand draw, and drop sticky-note comments on PDFs, images, and text submissions — all without leaving the WordPress grading interface. Annotations save automatically, are visible to students when the submission is returned, and the PDF viewer includes a zoom toolbar so you can dig into details on long documents.
Can I check submissions for AI-generated content or plagiarism?
Yes, with the Enterprise addon. AI Content & Plagiarism Detection runs submitted text through your choice of Winston AI, GPTZero, or Originality.ai. Checks can run automatically on submission or be triggered manually per submission. The grading panel surfaces the scores with colour-coded interpretation labels, matched-source counts, and a one-click "Insert plagiarism summary" button that drops a provider-specific summary into your feedback. A cohort-wide Plagiarism Report shows AI-likelihood and originality distributions plus a paginated flagged-submissions table.
Does PressPrimer Assignment integrate with my LRS or xAPI pipeline?
Yes, with the School addon. PressPrimer Assignment can emit Experience API (xAPI) statements to your Learning Record Store when students submit, grades are saved, and submissions are returned. The settings page includes a Test Connection workflow, a queue with retry handling, and per-event toggles so you can decide which actions are reported.

- Added: Duplicate assignment action available as a row action, bulk action, and editor toolbar button — copies all settings and taxonomy into a new draft owned by the current user
- Added: New
pressprimer_assignment_assignment_duplicatedaction hook so addons can copy their own per-assignment data - Added: Returned submissions render inline on the student view so grader annotations from the School addon are visible to students
- Fixed: Submission scores no longer shift retroactively when an assignment's max points is later edited — the Reports page, admin submission detail, the student assignment page (current returned card and the resubmission history), and the [ppa_my_submissions] dashboard widget all use the max points value recorded at grade time
- Fixed: The Re-extract text button is no longer shown to students on the assignment page and no longer appears on submissions that have already been graded or returned (it overwrites the extracted text, which shouldn't happen after grading)
