Column Headings

A more detailed description is here. 

• order_id

  • • These id's are chronological, and refer to the id of the original problem log.

• assignment_id

  • • Two different assignments can have the same sequence id. Each assignment is specific to a single teacher/class.

• user_id

  • • The ID of the student doing the problem.

• assistment_id

  • • The ID of the ASSISTment. An ASSISTment consists of one or more problems.

• problem_id

  • • The ID of the problem.

• original

  • • 1 = Main problem

    • 0 = Scaffolding problem

• correct

  • • 1 = Correct on first attempt

    • 0 = Incorrect on first attempt, or asked for help.

• • This column is often the target for prediction

• attempt_count

  • • Number of student attempts on this problem.

• ms_first_response

  • • The time in milliseconds for the student's first response.

• tutor_mode

  • • tutor, test mode, pre-test, or post-test

• answer_type

  • • choose_1: Multiple choice (radio buttons)

    • algebra: Math evaluated string (text box)

    • fill_in: Simple string-compared answer (text box)

    • open_response: Records student answer, but their response is always marked correct

• sequence_id

  • • The content id of the problem set. Different assignments that assign the same problem set will have the same sequence id.

• student_class_id

  • • The class ID.

• position

  • • Assignment position on the class assignments page.

• problem_set_type

  • • Linear - Student completes all problems in a predetermined order.

    • Random - Student completes all problems, but each student is presented with the problems in a different random order.

    • Mastery - Random order, and student must "master" the problem set by getting a certain number of questions correct in a row before being able to continue.

• base_sequence_id

  • • This is to account for if a sequence has been copied. This will point to the original copy, or be the same as sequence_id if it hasn't been copied.

• school_id

• • The ID of the school where the problem was assigned.

• hint_count

• • Number of student attempts on this problem.

• hint_total

• • Number of possible hints on this problem.

• overlap_time

• • The time in milliseconds for the student's overlap time.

• template_id

• • The template ID of the ASSISTment. ASSISTments with the same template ID have similar questions.

• answer_id

• • The answer ID for multi-choice questions.

• answer_text

• • The answer text for fill-in questions.

• first_action

• • The type of first action: attemp or ask for a hint.

• bottom_hint

  • • Whether or not the student asks for all hints.

• opportunity

• • The number of opportunities the student has to practice on this skill.

• opportunity_original
