email to complete wRite Formula v2

Thanks again for your valuable feedback and patience. I’m pleased to share that the wRite Formuala v2 is now functioning more reliably and has enabled progress on several important improvements to the wRiteFormula interactive.

Key Changes Implemented:

1. MCQ Option Curation

• Distractor options are now better aligned with the Game Content Database to reduce irrelevant or nonsensical suggestions. 

  

  all 4 options good distractors in words

  

  options are close distractors now

  
  
  

• Distractors such as "PbO" or "MnO2" that are chemically unrelated to selected ions (e.g., K+ and I-) are now excluded.

• Feedback for incorrect responses is being refined to better match the specific misconceptions each distractor is meant to target.

  

  most feedback are now, skillful teacher comments type, while some are just "Incorrect. Try again"

  

  improve teaching feedback where possible.

  
  
  
  
  
  
  
  
  
  
  

2. Feedback Improvements

• Feedback that was previously generic (e.g., "Try again!") is now being adjusted to reference naming rules and ion charges, though further refinement is still ongoing. 

  

  some feedback are still generic, if need can try targeted feedback if you have suggestions

  
  

3. Enhanced Ion Selection Mechanism

• The game now requires students to select ions in correct ratios to form a neutral compound before proceeding to MCQ (e.g., 2x Al3+ and 3x O2- for Al2O3), aligning with the original pedagogical intent. Thanks to Per Xian for the many inputs, files and ideas to work on, to revive this wRite Formula v2 as a HTML5 in SLS.

4. Fixes to Known Issues

• The prior bug where no valid answer was included in the MCQ has been resolved by randomising one correct option and three distractors. Thanks to testers like Chang Ci, this bug was resolved quickly.

5. Level Selector (new!)

•     A Lever selector Level 1 to 20 was added so this is a enhancement that was added absent in the original game. This will ensure that students can get a real chance to try out all the complicated chemistry bonding to experience the full suite of questions. Thanks to Stephanie for the suggestions.

6. Data Log of Students' attempt for self reflection.

• At the end of the 90 second game, there will be a log of all the actions that the student had taken both correct and wrong to allow for self reflection.

7. SLS as data analytics monitoring (new SLS feature live March 2025)

• Using SLS native xapi support for HTML5, I manage to record and send the scores and feedback to be stored in SLS question as teacher's comments. This should allow some level of similarity to the old app that has data analytics server running for teachers' to review students' actions and identify their mistaken etc.

Thank you everyone again for highlighting the need to preserve pedagogical design and the curated database. These updates aim to bring the HTML5 version closer to the effectiveness of the original mobile app unavailable since some years back.

Please let me know if there are any remaining issues or further refinements you'd like prioritised.
