1 Extract the data
1.1 Read it
Read in the sample learning outcome data. There are two assessments per student. Both of these are applied university-wide.
1.2 Describe it
Each record consists of six pieces of data:
internal_student_id
: the random student ID that does not identify the student in the real world but merely indicates which two records represent the same studentgender_identifier
: the gender of the student; can take valuesM
(male),F
, (female), andO
(other)race_ethnicity_code
: this identifies the race/ethnicity of the student:school_class_identifier
: this identifies the class of the student:1
(freshman),2
(sophomore),3
(junior),4
(senior); no other values are allowedSkill
: the skill being measured for a particular student. It is eitherU_EFFORT
(classroom effort) orU_WRITE
(writing effectiveness). More on this below in Section 1.3.Rating
: the rating of that particular skill for that student. Again, more on this below in Section 1.3.
1.3 The Learning Outcomes
1.3.1 Description
- Discipline Writing (
U_WRITE
) -
Writing effectiveness in the style most appropriate to the course, including knowledge of conventions.
- Effort (
U_EFFORT
) -
How much effort do you think the student put into the class?
1.3.2 Scales
The following are the abbreviated scales.
- Discipline Writing (
U_WRITE
) -
- 0-Remedial: The student is not demonstrating the skill or knowledge sophistication that aligns with the Furman expectation of entering college students.
- 4-Ready to graduate: The student demonstrates the level of competency we expect of our graduates.
- Effort (
U_EFFORT
) -
- 0-Little effort: The student seemed to put in a minimal amount of work
- 2-Outstanding effort: The student went above and beyond expectations
1.4 See the data
To get an idea of the data that has been read in, here are the first six rows of the table.
