What is Data SGP?

Data sgp is an analysis tool for longitudinal student assessment data that creates statistical growth plots (SGPs) which provide visual evidence of student progress relative to their academic peers. SGPs are calculated from students’ standardized test scores and covariate information using a “growth standard”, established by their prior testing history.

Educators can use SGPs to identify low performing students who need extra help and high performers who are ahead of their peers. SGPs also provide a clearer picture of what it will take for students to meet their achievement targets and goals.

SGPs can be generated for a single student or an entire class of students. The SGPs produced are comparable across classrooms, schools and even states, enabling educators to compare performance among their peers nationally. In addition, SGPs can be used to inform teacher goal setting and accountability.

To generate SGPs, a student’s standardized test scores and grade level progression are analyzed. The results are then compared to the growth standards set by the state. The percentile difference in the SGP is calculated and compared to the student’s previous test score. If the SGP is above or below the growth standard, then the student has either exceeded or failed to reach their target.

Aside from the growth percentile, teachers can get an idea of how much a student has grown by looking at their absolute score in comparison to other students’. This is the most useful metric and it helps teachers to see how far their students have come from where they were when they first took the test. The SGP can also give a teacher an idea of how to improve their teaching and to provide support for struggling students.

While SGPs are not a replacement for traditional metrics like mean, median and mode, they do provide a more accurate snapshot of a student’s performance over time. These new indicators allow for a more informed assessment of student learning and should complement current state achievement standards.

SGP data can be downloaded from each state’s website. Once a school or district has registered, it will be able to access reports specific to its needs and download individual student growth data. Many states also provide a SGP Scoreboard, which allows educators to see how students performed on each content area test.

The SGP package includes a sample WIDE format data set sgpData, which models the type of time dependent data required for the lower level functions, studentGrowthPercentiles and studentGrowthProjections. The SGPdata vignette contains more detailed instructions on how to work with this data set.

When working with SGP analyses, it is important to have the right software/hardware and to ensure that the data preparation is done correctly. In almost all cases, errors that come up during SGP analyses revert back to issues with the data preparation. Fortunately, once the data is prepared properly, SGP calculations are relatively straightforward.

The Neilma Sidney Prize

The Sydney Prize honours scientists and writers who are making a positive contribution to society through their work. Its aim is to recognise excellence in science and to encourage people to read more about the achievements of others. This year’s winners include a journalist, a photographer and a doctor. The winner of the 2024 Neilma Sidney prize will be published in Overland’s autumn issue. First prize is $5000, with two runners up each receiving $750. The judges and the editors are very pleased to have a talented group of writers in the running for this year’s award.

The award was founded in memory of Hertz Fellow Raymond Sidney, who was dedicated to building the Hertz community and encouraging other Hertz Fellows to participate in its activities and contribute to their success. The award is presented each year to a Hertz Fellow who has demonstrated a commitment to the goals of the fellowship, and to the mission of the Foundation as a whole.

Each year the Sydney Peace Prize is awarded to a nominee who promotes “peace with justice”, human rights and non-violence. The 2023 winner is Nazanin Boniadi, a leading activist in the global campaign for women’s rights in Iran.

Nazanin’s work is exemplary, demonstrating that even in the face of great political and social challenges a person can be a force for good. The prize is a recognition of her tireless efforts to stand up for what she believes in, and to turn outrage into action. It is also a signal to the global community that the repression and oppression of women and girls is a grave and serious threat to peace, security and well-being.

The prize was established in 1998 by contributions from friends of the late Professor Sidney H. Ingbar and his family. It is awarded to an outstanding scholarly book on the history of technology, or on the intersection between the history of technology and other fields of study such as art, culture, literature, or philosophy. The prize consists of $3500 and a plaque.

In the field of thyroid research, Dr. Sidney Hales was a pioneer and an innovator. His discoveries helped revolutionize treatment for autoimmune thyroid disease. The award honors his achievements in thyroid research, as well as his dedication to education and the advancement of women.

This year, the Hertz Fellowship Committee is raising funds to establish a permanent memorial for Sidney Cox. Letters are being sent to those on the original list and contributions are welcome from anyone who would like to support the effort. Checks should be sent to Professor Harry T. Schultz ’37 at 1 Occom Ridge in Hanover.
