| Note: Dashboard content is dynamically populated based on the user’s enrolled courses and group membership. Users not yet enrolled in any course will see an empty state with a prompt to browse available courses. |
|
WF-03 Use the Dashboard – Group Leader User: Group Leader |
Overview
The Group Leader Dashboard extends the individual view with cohort management capabilities: tracking learner progress, reviewing submitted scans, and monitoring group-level completion and performance metrics.
Preconditions
-
Users have been granted Group Leader status for at least one group.
-
At least one learner is assigned to the group.
Step-by-Step
| # | User Action | Expected Result / System Response |
|---|---|---|
| 1 | Log in to ScanHub (see WF-01). | The user lands on the Dashboard. A Group Leader panel or tab is visible alongside the personal learner view. |
| 2 | Navigate to the Group / Cohort panel. | A list of learners in the group is displayed with name, enrolment status, scans submitted, and last active date. |
| 3 | Select Group | When enrolled as a GL in more than one group, select/search the correct group from the Select Group drop-down menu |
| 4 | Select Sub-Group | When more than one group is enrolled within a group, select/search the correct sub-group from the Select Sub-Group drop-down menu |
| 5 | Select Course | When Sub-groups are enrolled in more than one course, select/search the correct course from the Select Course drop-down menu |

| 7 | Click on an individual learner’s name or row. | A detailed view of that learner’s activity opens: course progress, scan history, quiz scores, and pending items. |
| 8 | Review the Pending Scans section. | A list of scans submitted by group members awaiting review is shown, sorted by submission date. |
| 10 | Review the Group Progress metrics widget. | Aggregate charts display overall group completion rate, average quiz scores, total scans submitted vs. target, and individual outliers. |
| 11 | Filter the group list by status (e.g., Active, Inactive, Behind). | The learner list filters accordingly, allowing targeted follow-up. |
| 12 | Export or copy group progress data (if available). | A CSV or report download is triggered with current group metrics. |
| Note: Group Leaders retain access to their own individual learner dashboard. The dual view should be clearly separated in the UI. If a Group Leader is also enrolled in a fellowship as a learner, their personal progress is tracked independently. |
| Edge Cases: A Group Leader with no pending scans to review should see a clear empty state. Groups with more than 20 learners should paginate the learner list. |
|
WF-04 Navigate Courses & Complete Quiz Sections User: Individual Learner |
Overview
This workflow covers how a user accesses an enrolled course, navigates through its topic and module structure, consumes learning content (video lessons, reading material, embedded resources), and completes in-course quiz sections. It also covers progress tracking and returning to a partially completed course.
Preconditions
-
The user is authenticated and has at least one active course or fellowship enrolment.
-
The enrolled course has at least one module or topic published and available.
Part A — Accessing and Navigating a Course
| # | User Action | Expected Result / System Response |
|---|---|---|
| 1 | Log in to ScanHub (see WF-01) and arrive at the Dashboard. | Dashboard displays enrolled course cards with title, progress percentage, and a Start or Resume button. |
| 2 | Navigate to Courses | The courses landing page opens, displaying all enrolled courses tiles |
| 3 | Click Resume (or Start) on the desired course card. | The course landing page opens, displaying the course title, description, total modules, estimated duration, and overall completion progress bar. |
| 4 | Review the course outline / table of contents in the left-hand sidebar or content panel. | A structured list of Topics and Modules is shown. Each item displays its title and a status icon: Not Started, In Progress, or Completed. |
| 5 | Click on a Topic heading to expand it. | The topic expands to reveal its constituent modules (lessons, readings, quizzes). Locked modules (if sequential gating is enabled) are visually marked as locked. |
| 6 | Click on the first available (unlocked) module. | The module content view loads in the main content area. The sidebar highlights the active module. |
| 7 | Consume the module content: watch a video lesson. | The video player loads inline. Controls include play/pause, volume, playback speed, and full-screen. Progress is tracked; the module is not marked complete until the video reaches a defined watch threshold. |
| 8 | Scroll down to review supplementary reading material or embedded resources (PDFs, images, external links) below the video. | Reading material renders inline. Downloadable resources (e.g., pocket guides, reference sheets) provide a download link. |
| 9 | After consuming content, click the Mark as Complete or Next button. | The module is marked as Completed in the sidebar (green tick or equivalent). The system advances to the next module automatically or prompts the user to proceed. |
| 10 | Continue navigating through modules using the Next and Previous navigation buttons. | Each click advances or retreats one module. The sidebar updates the active position. Progress percentage on the course card updates. |
| 11 | Exit the course mid-way by navigating away or closing the browser. | Progress is auto-saved at the module level. On returning to the course, the user is offered a Resume prompt that returns them to the last active module. |
Part B — Completing a Quiz Section
Quiz sections appear at the end of topics or modules as a comprehension check. They are distinct from standalone Question Banks (WF-07) and Knowledge Challenges (WF-08) — they are embedded within the course flow and may gate progression to the next topic.
| # | User Action | Expected Result / System Response |
|---|---|---|
| 1 | Reach a Quiz module in the course outline (identified by a quiz or assessment icon) and click on it. | The quiz introduction screen loads, showing: quiz title, number of questions, estimated time, any passing score requirement, and a Start Quiz button. |
| 2 | Click Start Quiz. | The first quiz question is displayed. Questions may be multiple-choice (single or multi-select), image-based (with an embedded scan or diagram), or true/false. |
| 3 | Read the question and select an answer option. | The selected option is visually highlighted. For multi-select questions, multiple options may be toggled. |
| 4 | Click Next or Submit Answer. | Behaviour depends on quiz mode: Immediate feedback mode: correct/incorrect is shown at once with a brief explanation before advancing. End-of-quiz mode: answer is recorded silently and the next question loads without feedback. |
| 5 | For image-based questions: examine the displayed scan image or video clip before selecting an answer. | The image is displayed at sufficient resolution. A zoom or full-screen option is available. Video clips have playback controls. |
| 6 | Continue answering all questions and reach the final question. | A Submit Quiz or Finish button appears after the last question is answered. |
| 7 | Click Submit Quiz. | The quiz results screen loads showing: total score, pass/fail status (if a threshold is set), percentage correct, and time taken. |
| 8 | Review the per-question breakdown on the results screen. | Each question is listed with the user’s answer, the correct answer, and the explanation. Incorrect answers are highlighted. |
| 9 | If the quiz is failed (score below passing threshold) and retakes are permitted: click Retake Quiz. | The quiz restarts from question 1. Previously selected answers are cleared. Question order may be randomised on retake. |
| 10 | If the quiz is passed (or no passing threshold is set): click Continue or Proceed. | The quiz module is marked as Completed. The next module in the course unlocks. The user is advanced to the next module automatically or prompted to continue. |
Part C — Tracking Course Completion
| # | User Action | Expected Result / System Response |
|---|---|---|
| 1 | Return to the course landing page at any point during the course. | Overall progress bar reflects current completion percentage, calculated across all completed modules and passed quiz sections. |
| 2 | Review the module checklist in the sidebar. | Each module shows its individual completion status. Quizzes that have been passed show score alongside the completion tick. |
| 3 | Complete all modules and quizzes in the course. | Course progress reaches 100%. A course completion banner or modal is displayed, congratulating the user. |
| 4 | Access the completion certificate or CME/CPD credit record (if applicable). | A Download Certificate button or link to the credential record is presented. Certificate PDF is downloadable. |
| 5 | Return to the Dashboard. | The course card on the Dashboard now shows Completed status. The completion date is recorded in the user’s profile and progress history. |
| Sequential vs. Free Navigation: Some courses enforce sequential gating – a module only unlocks once the prior module is completed and its quiz passed. Others allow free navigation. The course configuration determines this behaviour; it should be clearly indicated on the course landing page before the user begins. |
|---|
| Quiz Retake Policy: Retake limits, cooldown periods, and whether previous attempts are visible to Group Leaders are course-level configuration settings. These should be surfaced to the user on the quiz introduction screen before they start. |
| Fellowship Courses: For fellowship tracks (POCUS Essentials Fellowship, OB Fellowship, etc.), quiz scores and module completion contribute directly to competency milestones tracked on the Group Leader Dashboard. The minimum passing score for fellowship quizzes must be enforced by the platform and clearly labelled in the quiz UI. |
|
