Abstract

A global architecture (GLP), as disclosed herein, is based on the thin server architectural pattern; it delivers all its services in the form of web services and there are no user interface components executed on the GLP. Each web service exposed by the GLP is stateless, which allows the GLP to be highly scalable. The GLP is further decomposed into components. Each component is a microservice, making the overall architecture fully decoupled. Each microservice has fail-over nodes and can scale up on demand. This means the GLP has no single point of failure, making the platform both highly scalable and available. The GLP architecture provides the capability to build and deploy a microservice instance for each course-recipient-user combination. Because each student interacts with their own microservice, this makes the GLP scale up to the limit of cloud resources available—i.e. near infinity.

Claims (65)

1. A system for hybrid content provisioning, the system comprising:

a memory comprising a learning-asset database comprising a plurality of learning assets each comprising a link directing to educational content, wherein at least some of the educational content is stored on a remote content platform; and

at least one server configured to execute a user microservice, wherein the at least one server is configured to:

identify a set of learning assets with each of the learning assets comprising a link to educational content and associated metadata;

automatically determine a sequencing of learning assets in the set of learning assets, wherein the sequencing is partially adaptive-based such that the sequencing is partially determined according to one or more machine learning models and partially non-adaptive-based such that the sequencing is partially determined according to one or more rules;

generate a graph-based representation of the set of learning assets based on the determined sequencing, the graph-based representation comprising nodes representing the set of learning assets and edges for linking the set of learning assets based on the sequencing;

receive a request for a local-user microservice that is unique to a specific user;

identify a portion of the graph-based representation relevant to the local-user microservice; and

provide a local copy of the portion of the graph-based representation relevant to the local-user microservice.

2. The system of claim 1 , wherein the at least one server is further configured to retrieve a content model associated with the set of learning assets.

3. The system of claim 2 , wherein the content model is retrieved from the memory.

4. The system of claim 1 , wherein the user microservice comprises a platform-user microservice and the at least one server is configured to execute the platform-user microservice to:

synchronize operation of the platform-user microservice and the local-user microservice;

persist user state data and identify next learning assets for presentation;

interact with the asset sequencer to select next learning assets according to the one or more machine learning models;

retrieve the identified next learning assets; and

evaluate performance of the user.

5. The system of claim 4 , wherein the at least one server is further configured to:

identify the requested local-user microservice from a set of pre-created local-user microservices; and

provide the requested local-user microservice.

6. The system of claim 5 , wherein the at least one server is further configured to synchronize state data by receiving updated state information identifying an updated state for the user.

7. The system of claim 6 , wherein the at least one server is further configured to, subsequent to synchronizing the state data:

receive a content request; and

select a next learning asset for presentation according to the one or more machine learning models.

8. The system of claim 7 , wherein the at least one server is further configured to provide the next learning asset to the local-user microservice.

9. The system of claim 8 , wherein the at least one server is further configured to:

receive a user response to the provided learning asset from the user;

evaluate the user response to the provided learning asset;

update a user model characterizing user mastery; and

update local user state data based on the updated user model.

10. A method of hybrid content provisioning, the method comprising:

identifying a set of learning assets by executing a microservice, each of the learning assets comprising a link to educational content and associated metadata;

automatically determining, by executing the microservice, a sequencing of learning assets in the set of learning assets, wherein the sequencing is partially adaptive-based such that the sequencing is partially determined according to one or more machine learning models and partially non-adaptive-based such that the sequencing is partially determined according to one or more rules;

generating a graph-based representation of the set of learning assets based on the determined sequencing, the graph-based representation comprising nodes representing the set of learning assets and edges for linking the set of learning assets based on the sequencing;

receiving a request for a local-user microservice that is unique to a specific user;

identifying a portion of the graph-based representation relevant to the local-user microservice; and

providing a local copy of the portion of the graph-based representation relevant to the local-user microservice.

11. The method of claim 10 , further comprising retrieving, by executing the microservice, a content model associated with the set of learning assets.

12. The method of claim 10 , further comprising:

identifying the requested local-user microservice from a set of pre-created local-user microservices; and

providing the requested local-user microservice.

13. The method of claim 12 , further comprising synchronizing state data by receiving updated state information identifying an updated state for a user.

14. The method of claim 13 , further comprising executing a platform-user microservice to:

synchronize operation of a platform-user microservice and the local-user microservice;

select learning assets for presentation to the user according to the one or more machine learning models;

present the learning assets to the user; and

evaluate performance of the user by scoring responses submitted by the user to the learning assets.

15. The method of claim 13 , further comprising, subsequent to synchronizing the state data:

receiving a content request; and

selecting, by executing a platform-user microservice, a next learning asset for presentation.

16. The method of claim 15 , further comprising providing the next learning asset to the local-user microservice.

17. The method of claim 16 , further comprising:

receiving a user response to the provided learning asset;

evaluating the user response to the provided learning asset;

updating a user model characterizing user mastery; and

updating local user state data based on the updated user model.

18. A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to implement operations comprising:

identifying a set of learning assets by executing a microservice, each of the learning assets comprising a link to educational content and associated metadata;

automatically determining, by executing the microservice, a sequencing of learning assets in the set of learning assets, wherein the sequencing is partially adaptive-based such that the sequencing is partially determined according to one or more machine learning models and partially non-adaptive-based such that the sequencing is partially determined according to one or more rules;
