This repository will hold the publicly released anonymized logs and scripts for DOI 10.1145/3478432.3499123

Update on June 17, 2025

• Specified column names in the cleaned datasets. The raw logs(final-time.tsv, midterm-time.tsv) were left unmodified.
  • curr_time: Elapsed time in milliseconds
  • id: Student ID
  • question: Question identifier in the format q<category_number>_<question_number>
  • score: Student's score on the specific question at the current timestamp

Time-Related Cleaning

1. clean_time_final.tsv and clean_time_mid.tsv Contain the cleaned time-related datasets for the final and midterm exams, respectively.
   Each included student ID has only valid (non-negative) curr_time entries and a complete set of questions.

The .tsv files below contain discarded entries from the original dataset during the cleaning process:

2. corrupted_time_final.tsv and corrupted_time_mid.tsv Contain all log entries for any student ID with at least one negative curr_time value.
   These entries were excluded under the assumption that negative timestamps indicate a corrupted log.
3. incomplete_time_final.tsv and incomplete_time_mid.tsv
   Contain all log entries for student IDs who viewed fewer or more than the number of questions assigned in the exam:
   • 7 questions for the midterm
   • 8 questions for the final
     These logs were excluded based on the assumption that a valid student log should include exactly all assigned questions for the midterm/final.

Non-Time-Related Cleaning

1. clean_non_time_final.tsv and clean_non_time_mid.tsv
   Contain the cleaned non-time-related datasets for the final and midterm exams, respectively.
   Each included student ID has a complete set of questions. These files may contain entries with negative curr_time values, as time was not a criterion for this cleaning.

The .tsv files below contain discarded entries from the original dataset during the cleaning process:

2. incomplete_non_time_final.tsv and incomplete_non_time_mid.tsv
   Contain all log entries for student IDs who viewed fewer or more than the number of questions assigned in the exam:
   • 7 questions for the midterm
   • 8 questions for the final
     These logs were excluded under the assumption that a valid student log should include exactly all assigned questions for the midterm/final.
