Announcements:

• 🔈RCD has been used in the 'Learning & Practice' business of the HUAWEI Educational Center APP, since 2022.

Environment Settings

• Torch version: '1.7.1'
• DGL version: '0.6.1'

Example to Run the Codes

To run the codes using the Junyi dataset:

1. Navigate to the code directory:

   cd RCD/RCD
   

2. Create two folders '/model' and '/result':

   mkdir model result
   

3. Build exercise-concept correlation local map:

   python build_k_e_graph.py
   

4. Build student-exercise interaction local map:

   python build_u_e_graph.py
   

5. Train and test RCD model:

   python main.py
   

Note: Exercise-concept correlation local map and student-exercise interaction local map can be constructed by running build_k_e_graph.py and build_u_e_graph.py respectively.

Dataset

Junyi

• log_data.json: Student exercising records. Source
• train_set.json: Data file for training.
• test_set.json: Data file for testing.
• graph/K_Directed.txt: Prerequisite relation from concept dependency local map, where each line is a prerequisite relation from the concept dependency local map: precursor_concept_ID\t succeed_concept_ID.
• graph/K_Undirected.txt: Similarity relation from concept dependency local map, where each line is a similarity relation from concept dependency local map: concept_ID\t similar_concept_ID.

Note: Concept dependency local map construction details are provided in the paper.

ASSIST

• log_data.json: Student exercising records.
