Dataset Introduction

OcarinaKT is a music performance assessment dataset in the field of knowledge tracing, aiming to use knowledge tracing methods to capture the dynamic changes in learners’ playing abilities. The dataset collects data from a public ocarina performance challenge event, where users recorded their performances on an intelligent practice platform and received instant scores. Only users who passed previous levels were allowed to enter subsequent levels. The dataset includes a main response record table (RecordDS) and two supplementary information tables (UserDS, OpernDS). The UserDS table records the performance information of 1,442 learners included in the dataset, while the OpernDS table records score (sheet music) information.

Here is the explanation of the fields in each table:

• Answering record table RecordDS:

  Field	Description
  user_id	Student ID
  opern_id	Score (sheet music) ID
  record_id	Record ID
  pitch_score	A sequence recording the pitch score of each note in the score
  rhythm_score	A sequence recording the rhythm score of each note in the score

• Students' information table UserDS:

  Field	Description
  user_id	Student ID
  practice_count	Number of practice attempts by the student

• Sheet music information table OpernDS:

  Field	Description
  opern_id	Score (sheet music) ID
  practice_count	Number of times this score has been practiced
  question_ids	A sequence recording the question ID of each note in the score
  skill_ids	A sequence recording the skill ID associated with each note in the score
