New Growth Model Shows Student Improvement

by at 4:23 pm.

In the midst of all the politicking and rhetoric, it’s nice to see something positive about our schools. From the office of the Superintendent, a press release showcasing how Lowell quite holds its own in the new growth measures from the state.

Lowell demonstrates strength in new state growth measures

[LOWELL] – The median or “typical” student in Lowell grew at the 49th percentile in English language arts and at the 55th percentile in mathematics, according to the state’s new growth model released on Tuesday that compares students with similar MCAS score histories. The district scores showed growth in English Language Arts consistent with statewide growth rates, and the district showed strong levels of growth in Mathematics, particularly in the middle schools.

Among the findings:
• Lowell’s 55th percentile growth in Mathematics was at the top of the list of 27 urban districts.
• Only three Greater Lowell districts (Groton-Dunstable, Shawsheen, and North Middlesex) had a higher Mathematics growth score than Lowell.
• Lowell’s 66th percentile growth in Grade 6 Mathematics topped the list of urban districts and Greater Lowell districts.
• The Moody Elementary School had among the highest growth scores in the state (81st percentile English Language Arts, 81st percentile Mathematics).
• Seven Lowell schools (Moody, Wang, Stoklosa, Morey, Lincoln, Pyne Arts, Daley) had median Student Growth Percentiles [SGPs] scores above the 60th percentile (high growth) in Mathematics, and the remaining schools had scores above the 40th percentile (moderate growth).
• Four Lowell schools (Moody, Daley, Lincoln, Wang) had median SGP scores above the 60th percentile (high growth) in English Language Arts. Of the remaining 18 schools, 11 had scores above the 40th percentile (moderate growth).
• The Moody, Morey, and Lincoln had the highest growth rates of the district’s elementary schools.
• The Wang, Stoklosa, and Daley had the highest growth rates of the district’s middle schools.

School and district growth reports are developed by aggregating the student growth percentiles for all students in the school or district to determine the median student growth percentile. Results are calculated only for students in grades 5–8 who have two or more consecutive years of MCAS results, students in grade 4 with MCAS results from grade 3, and students in grade 10 with MCAS results from grade 8. Students are grouped with their “academic peers,” other students in the state with a similar MCAS performance history on the 2007 and 2008 MCAS English and mathematics exams. Their 2009 scores are then compared to others in their statewide peer group, and ranked by percentile.

According to the growth model results, high growth is defined as growth in a subject at or above the 60th percentile, typical growth is between the 40th and 60th percentile, and low growth is below the 40th percentile. A student scoring in the 60th percentile did better on the 2009 MCAS exam than 60% of their statewide academic peers.

Schools and districts have their median Student Growth Percentiles [SGPs] score for each grade and subject posted on the Department of Elementary and Secondary Education website. The reported value compares the school or district’s median student (middle of the distribution) with the statewide median (50th percentile).

Small differences in the median SGPs are insignificant, so the district’s growth in English Language Arts is virtually identical to the rate of growth in the state. The district’s growth rates in Mathematics ranked at the top of all urban school districts, and among the top five districts in Greater Lowell. Lowell’s rate of growth in sixth grade was among the highest in the state.

This is the first time Massachusetts has used a growth model to evaluate student performance. The results measure individual student progress on the state’s assessment test by tracking the scores from one year to the next. Whereas basic test results reflect how a student performed on a particular assessment, growth reports detail how much the student’s performance has changed from year to year compared to students with similar test score histories.

    So basically students at the Reilly and Sullivan are not showing as much year over year growth as the students at the Moody, Morey, Lincoln, Wang, Stoklosa, and Daley. Very interesting. Pay a lot of $$ to live in the “best” section of Lowell and your child gets an inferior education. It’s no wonder most folks who grew up in Belvidere have moved to the burbs to raise a family. James F. Sullivan is rolling over in his grave right now.

    I have to agree that the growth model will quickly disagree with people if it shows growth in schools that were lower performing and schools like the Reilly, Pyne, and Sullivan, are showing no growth. Yes, I expect profound growth too! My daughter has been moved from her desk 3 times and has been unable to make social ties in the name of helping under-performers
    (She is bright and I was told she was moved because she was a good example for non-english language speakers) Sorry but it is my child and she is not the teacher and her scores will drop which will not help the MCAS scores overall. I love her helping but she will be pulled down!

    The growth model may be flawed if it doesn’t account for the lesser ability to grow that occurs when one approaches the top of the scale.

    But even worse if the top students are being restricted in an attempt to bring up the bottom group. All students should be helped, but some should not be restricted in the attempt to improve the others. We need the top students to get even better, as well as the bottom students to move up.

    I could not agree more! When I was in school we had programs like project enterprise for children that excelled and children were broken off into reading levels. I think the theory of having children uplift other children is fantastic as long as we also do not hold children that excel down. The Lowell schools push on our small children to help their neighbor with their work and let them know their behavior is not correct. I just think this is way too much for a 6 year old to teach another 6 year old. We as adults need to do this! This new testing system concerns me.

    So, as a parent with children in the Lowell Public Schools, I’d like to know exactly what the “Growth Model” is? As far as the percentiles, I know where they stand…just curious about this issue..

  6. Kim Says:

    The growth model measures the percentage of growth that an individual child has achieved on the MCAS. Lowell has some subgroups that have shown tremendous growth but still do not pass the MCAS. Lowell wants to show that they may have had to work harder to get these children to the level that they are at vs. another community that did not have the ESL or special ed population that we have. It is a much more fair way to rate MCAS scores then the current system. The only problem that I have with it is that Lowell has school populations that are not in these “risk” groups and still many of them fail to thrive in the Lowell Schools and I am not convinced on using other chidlren to push the growth effort.

  7. Kim Says:

    I guess I need to know if a child barely passes the MCAS but never improves is that a negative reflection on Lowell schools? Does the system require growth from high level learners also?

  8. I don't support the van plan anymore Says:

    I just read an article on Boston.com titled “Grade the teachers”. It mentions the Ma. new growth model…”Last week, Massachusetts state education officials unveiled a value-added data system that can track the growth in individual students’ achievement from year to year. State officials have not laid out any formal plans to use it to assess teacher effectiveness, but it seems clear that there is interest in moving in that direction, and the state plans to cite the new database in its application for Race to the Top funds.”
    Looks like Ma. is moving toward merit pay for teachers. Thank God! We need to motivate and reward good teachers! AND weed out the bad ones. I just hope it happens before my child enters the Lowell public school system.
