The data sgp is an invaluable tool for students, parents, educators and administrators. It gives a fuller picture of student learning and performance and allows educators to analyze the effectiveness of their instruction and identify areas for improvement. In addition, administrators can use data sgp to monitor school and district performance and to help inform decisions regarding curriculum development, instruction methods and professional development programs.
Data sgp can be found within the Star Growth Report in each student’s Profile/Growth dashboard. The data displayed is a combination of up to five years of student test score history, including the 2014-15 Badger year. The resulting growth percentiles are calculated by comparing each students current performance to that of all students with comparable assessment histories on the same subject-matter tests.
This exemplar data set sgpData is anonymized and contains five years of annual, vertically scaled, assessment data in WIDE format. It serves as an example for the data that should be provided to lower level SGP functions, such as studentGrowthPercentiles and studentGrowthProjections.
The sgpData dataset is regularly updated by the state and provides students with a view of their progress over time. It includes a summary of the student’s overall performance, with special emphasis on achievement in subject matter. It also highlights the students progress towards reaching academic goals in key content areas and helps teachers to focus their instruction. In addition to the sgpData, schools receive additional student data that helps them to improve learning. This includes data from the National Center for Education Statistics and from the Illinois State Board of Education.
In order to make the most of SGP data, it is important for users to understand its structure. The sgpData dataset is an anonymized, panel data set that includes five years of annual, vertically scaled, assessments in WIDE format. The first column should provide a unique student identifier and the remaining columns should include the grade level/time associated with the students assessment occurrences.
Using SGP data requires the user to have familiarity with the open-source programming language R, which can be downloaded for free from the CRAN website. The SGP package provides an extensive collection of R functions for SGP analysis. In addition, there are numerous resources available on the CRAN site to help newcomers to R get started with their SGP analysis.
To make the most of the sgpData dataset, it is recommended that the data be downloaded in long format for operational analyses. This form makes it easy to manage the data and to update analyses with additional years of data. In addition, higher level SGP functions often assume that the embedded SGPstateData meta-data is present in the long format data set. This saves time when preparing the initial data set for an SGP calculation. However, the data can be easily converted to wide format for operational analysis. In addition, all higher level SGP functions are designed to work with long format data. This makes it very simple to upgrade analyses with new or additional years of data without having to modify existing analyses.
