What is Data SGP?
Data sgp is an information database of student performance data. Its analyses can assist educators with pinpointing problems of student achievement. It’s important to understand how it works and its implications before attempting an analysis – missing or misinterpreting preparation steps can lead to misleading or inaccurate results.
While the term “big data” has become a popular buzzword, data sgp is not big in the grand scheme of things – by comparison to global Facebook interactions, for example, it’s relatively small. This is due to the fact that the datasets involved are relatively small compared to other data-intensive fields, such as scientific research or global commerce.
SGPs are percentile scores that place a student’s growth in context with other students who have similar test score histories. They are reported on a scale of 1 to 99, and if a student’s SGP is 45, this means that they out-grew the 45th percentile of academically-similar students. This information is helpful in understanding a student’s relative performance, and it can be used to help identify both high achieving students and those that need additional support.
SED has published a number of interactive data tools that allow you to explore and analyze the sgp data. These can be found at the BAA Secure Site under “Reports” -> “Data Tools”.
When creating a sgp graph, it is important to understand that the SGP is a measure of relative performance. In other words, the SGP represents the amount a student has improved compared to other students with similar test scores. As such, it is important to note that a student with a lower SGP has a more difficult time improving than a student with a higher SGP.
While SGPs are not perfect, they do provide a useful tool for teachers in their assessment of student learning. As such, it is important to view the SGP as an addition to existing student achievement measures, rather than a replacement for them.
Using SGPs can help you identify a student’s strengths and areas for improvement, so that you can plan the most effective interventions for each student in your class. SGPs also offer valuable insight into the effects of different teaching methods and strategies.
SGPs are calculated based on up to five years of student test score history, including the 2014-15 Badger year. The individual SGPs for each teacher are then averaged to give the teacher a mean growth percentile, or MGP. The MGP tells you, on average, how much a teacher’s students have improved compared to similar students.
The sgpData_LONG set contains a subset of the sgpData_WIDE data that is required for running SGP analyses. It contains the following variables: VALID_CASE, CONTENT_AREA, YEAR, ID, SCALE_SCORE and GRADE. In addition, sgpData_INSTRUCTOR_NUMBER is an optional variable that provides the lookup table for the student-instructor association in the SGP analysis process. It is only needed if running student growth projections or individual level student growth and achievement plots. This set is available from the BAA Secure Site under “Reports” -> “Data Tools” -> sgpData_LONG.
