Why one shared vocabulary list is not enough
“First 100 words” lists are useful starting points, but children do not live in identical contexts. One child may be fascinated by fire trucks, another may be preparing for a zoo visit, while another needs words related to preschool routines.
If every child always receives the same list, it is harder for parents to connect screen-based learning with real-life conversation.
KidEnglish therefore manages vocabulary per child profile instead of relying on a single device-wide list.
Two useful layers: general vocabulary and focused learning vocabulary
Each child profile can manage two key groups:
- Global vocabulary: a broader pool that can appear across games.
- Learning vocabulary: a focused group prioritized for current learning.
This means parents do not have to remove familiar words simply to focus on a new topic. A word can remain in the broader pool without being the main learning target right now.
Parents can choose from system vocabulary
KidEnglish includes a system vocabulary catalog. Parents can select existing words rather than creating every item manually.
System items keep the canonical word used by gameplay so learning screens display the actual vocabulary item rather than a generic administration label.
When vocabulary is fetched from the server, remote image/audio media can also be registered for use by learning screens, including words that were not part of an older bundled asset map.
What about family-specific custom words?
The parent flow also supports custom vocabulary. Depending on the configured path, a new word can use uploaded media or AI-assisted image generation.
The backend includes child-safe vocabulary moderation before parent-created vocabulary reaches final media/persistence. When an AI moderation provider is configured, it can be used alongside a local denylist fallback.
This does not mean arbitrary internet content is automatically safe. It means the KidEnglish custom-vocabulary flow has a dedicated moderation step instead of passing parent input directly into a child experience.
How does personalized vocabulary reach games?
Personalized gameplay flows prefer vocabulary associated with the selected child/user instead of relying only on a fixed system pool.
Some current PlayGame flows also mix focused learning vocabulary with the broader pool so children receive repetition without seeing an identical set of answers every time.
For parents, the important point is that the vocabulary list is not merely a note in Parent Portal; it can become input for lessons and games.
How does this work with Adaptive Learning?
The two features complement each other:
1. Parents choose which vocabulary belongs in the learning scope. 2. Adaptive Learning uses explicit-target practice outcomes to decide which words inside that scope should receive more attention.
For example, a parent selects 20 food words. After several sessions, the child consistently recognizes “apple” but still confuses “flour” and “sugar.” Adaptive Learning can prioritize the weaker items without requiring the parent to reorder the list after every lesson.
How many words should parents add at once?
KidEnglish provides the tools, but parents do not need to create a huge vocabulary library on day one.
A more practical approach is to:
- choose one topic the child meets in daily life;
- add a small useful group;
- reuse those words during conversation, books or outings;
- notice which words are recognized quickly or slowly;
- rotate the focused group as the child becomes comfortable.
The purpose of personalization is not “more words is always better.” It is making screen-based vocabulary meaningful in the child's world.
Can siblings have different lists?
Yes. Vocabulary belongs to the child profile, so siblings can have different learning pools under the same parent account.
That is especially useful when ages or interests differ. A younger child can focus on familiar objects and animals while an older child works with a broader vocabulary range.
Conclusion
Personalized vocabulary changes the question from “How many words does the app have?” to a more useful one: “Are the words my child needs appearing often enough?”
KidEnglish lets parents choose the scope, keep vocabulary separate per child and combine it with Adaptive Learning to prioritize practice.
