Why the VTS Editor Switch Block Speeds Up Your E-Learning Scenarios
When managing a large-scale e-learning program (multi-country onboarding, compliance, safety, job support), every design choice impacts maintenance, robustness, learner experience, and iteration speed. The VTS Editor Switch Block directly addresses these needs: it centralizes your branches into a single decision point and replaces hard-to-read cascades of conditions.
For a training manager, instructional designer, or HR leader, this translates to clearer flows, faster variant production, and easier control of adaptive learning paths. To explore the full ecosystem, visit the VTS Editor page and learn more about deployment capabilities via VTS Perform.
Definition and Key Benefits of the VTS Editor Switch Block
Simple Principle, Big Impact
The Switch activates output n based on a variable expression that returns an integer from 1 to N (N = number of routes). If the value is out of bounds, the last output serves as the “default.” Instead of multiplying “if/then” (n == 1, n == 2, n == 3…), you calculate an index, wire the outputs, and centralize the routing.
Immediate Gains for Your Projects
- Lighter, clearer, and easily auditable flows at a glance
- Fewer failure points (wiring errors, missing cases)
- Simplified maintenance (logic managed in one place)
- Faster production and variants (levels, jobs, countries)
These best practices reduce cognitive load for both designers and learners; see UNSW’s summary on Cognitive Load Theory.
Why You Should Avoid Stacking Conditions
The Limits of Chained “if/else”
Stacking Conditions and Flags works… until another case is added, a scoring system evolves, or a new variant is required. The flowchart quickly becomes tentacular and hard to navigate, with risks of regression or dead ends.
The Useful Discipline of the Switch
The Switch enforces a clear approach: an index variable, an explicit upper bound, one route per case, and a “safety net” output. The result: easier to reread, test, document, and share—especially in teams.
Who Can Benefit and for What Use Cases
Target Audiences
- Instructional Designers (non-linear paths, adaptive assessment)
- Training Managers (variants by level, job, language/region)
- HR Leaders (onboarding, compliance, safety, soft skills)
Common Use Cases
- Quiz routing based on performance
- Branching dialogues in serious games
- Optional chapters, automated remediation/deepening
- Theme-based paths chosen by the learner
To see a high-impact example, explore the Manpower customer case (immersive training and significantly increased engagement).
Configuring the VTS Editor Switch Block
Essential Settings
The Switch expects a variable expression that returns an integer. If index = 1, output 1; if 2, output 2, etc. For values < 1, > N, or invalid, the last output (default) is triggered. Use it as a safety catch: display a clear message, return to a menu, or fallback procedure.
Prepare the Data: Build the Index (INTEGRAL Pack)
- Convert score thresholds into an index (Score/Check Score)
- Use a Counter (attempts/passages)
- Introduce variety via randomness (random variable or Random Block)
- Transform Quiz results, Phrase Choices, Numeric Field into a single index
- Leverage external data (Web/AI Request) converted into integers
3 Quick Use Cases
- Random question: store a number from 1 to 10, then Switch to Q1…Q10
- Chapter menu: use “chapterIndex” (1…N) and Switch to the right section
- Adaptive difficulty: index based on score/time; 1 = remediation, 2 = standard, 3 = advanced
Switch, Conditions, and Flags: Make the Right Choice
Simple Rule
Favor the Switch when your branches are numbered (1…N) or when a “distribution by index” logic naturally fits. Keep Conditions/Check Flags for mixing Boolean states (prerequisites in AND/OR). Both complement each other well: first check conditions, calculate a single index, then let the Switch handle distribution.

Powerful Branching with the VTS Editor Switch Block
Personalize by Performance (Switch + Score)
Imagine a common core, then three routes:
- Less than 50%: guided remediation (slideshow, help resource, targeted quizzes)
- 50–80%: consolidation (intermediate exercises, contextualized feedback)
- More than 80%: deepening (complex cases, immersive simulations)
Map these thresholds to an index (1, 2, or 3), then let the Switch distribute. Add Progression, Badge, and Score to manage skills and recognition.
Controlled Replayability (Variation and Limits)
- Vary with a random value (in a variable or via the Random block), covering all cases before repeating
- Limit attempts using a Counter: e.g., remediation on the first three tries
- Impose an order with Sequence, while letting the Switch choose the associated content
Streamline Your Content (Switch + Function Call and Groups)
Centralize reusable sequences (briefings, instructions) in a Group in Function mode. The Switch chooses the function to call based on the index. This drastically reduces duplication, and any update is applied everywhere.
Localization and Context (Switch + Language)
If the educational logic remains the same, keep the Switch at the core and direct to language-specific Groups (media, voice, references). If needed, begin with a Condition on language, then a Switch for each.
Turn Results into Useful Routes (Targeted Feedback)
- Targeted feedback: Message + Speak + Emotion + Animation
- Immediate remediation: Open Resource + Modify Resources
- Alternative route: realistic scene, riddle, mini-game to reinforce the concept
Adaptive approaches support active learning; see research from the Carnegie Mellon Open Learning Initiative.
Optimize, Test, and Maintain Your Switch Blocks
Readability, Conventions, and Review
- Clearly name your variables: routeIndex, chapterIndex, levelIndex
- Add a Note to the Switch to document the rule (thresholds, data sources)
- Structure by thematic Groups (Assessment, Remediation, Advanced)
- Use VTS Reviewer to have stakeholders review the flow
Safety Net: The “Default” Output
- Display a clear message and suggest a way back (menu, chapter, teleport)
- Log the event via Recap (e.g., “Out-of-range value for routeIndex”)
- Reset the variable or recalculate a valid index before retrying the activity
Performance and Stability
- Avoid uncontrolled loops to the same Switch
- For deliberate repetition, prefer Function Call and, if needed, Sequence
- Synchronize data blocks before the Switch (wait for Web/AI Request to finish, short Wait, or Countdown if time-sensitive)
Measurement and Management (SCORM / VTS Perform)
- Set Progression (33%, 66%, 100%) after each major branch
- Manage status and success with Score/Check Score
- Deliver the right doc at the right time (Open Resource + Modify Resources)
- If needed, mark completion for sending to VTS Perform or your LMS
Checklist for Testing Before Publishing
- In preview, open Variable State and observe routeIndex and its contributors
- Test boundaries: values < 1, > N, null; verify correct handling by the “default” output
- Verify replayability: variety (Random), limits (Counter), order (Sequence)
- Test returns and shortcuts: Checkpoint/Back and Teleport
- Ensure multilingual consistency: Condition on language, aligned media/voice, proofread texts
- Check SCORM/VTS Perform tracking: progression, status, score, reporting
Scale Up with the VTS Editor Switch Block
Clearer, Faster, More Engaging Scenarios
The Switch centralizes multi-branch logic, enhances readability and maintainability, and facilitates large-scale personalization. When combined with Variables (INTEGRAL Pack), Score/Check Score, Random, Counter, Sequence, Function Call, Language Condition, Progression, and contextual resources, you get truly adaptive and robust learning paths.
