2010 Erasure Analysis Report New Jersey Assessment of Skills and Knowledge (NJ ASK 3-8) Draft

November 2010


Introduction This report summarizes erasures analyses results for the 2010 administration of the NJ ASK for grades 3 through 8. Two approaches are considered to investigate irregularities in response patterns: 1) erasure rates based on student Wrong to Right (WTR) erasures, and 2) grade/subject level person-fit rates for each school based on student response patterns. The person-fit analysis is introduced this year per recommendation from NJ ASK Technical Advisory Committee meeting. This report is divided into two parts. In Part 1, aggregate erasure rates are analyzed using both operational and field-test data. The analysis is further extended to grade, grade/subject, and district factor group (DFG) level. In Part 2, the schools flagged for high erasure rates by grade and subject area for the operational tests are compared against the person-fit rates. A flag of the same school for a high erasure rate and a poor person-fit rate may be an indication of irregularities in the test administration.

Part 1. Erasures Analysis Aggregate Erasures for Grade, Subject, Subject/Grade, and DFG In this section, a summary of the total number of erasures and percentage of total erasures by erasure types across grades are presented first followed by the total erasures across subject areas in the NJ ASK tests. The total erasures by erasure type are then broken down into grades and subject areas and district factor groups (DFG). These aggregate erasures are presented with 2009 results side-by-side for comparison purpose. Finally, erasure rates by school (for all grades and subject areas) and by grade across subject areas are presented. The erasure analysis for NJ ASK grades 3 through 8 showed a total of 2,531,290 erasures. Quality control checks and verification procedures were implemented to ensure that reported erasures are valid. The percentage of WTR erasures and the mean number of erasures per student were two critical pieces of information for the erasure analysis. The percentage of WTR erasures were calculated by dividing the number of erasures that changed an incorrect response to a correct response by the total number of erasures. These calculations were aggregated by schools at the grade, subject, subject/grade, and DFG levels. Of the 2,531,290 total erasures, 58.52% involved changing an incorrect response to a correct response. Table 1 shows the total erasures and percentage of each type of erasures by grade. A comparison of the erasure results between 2009 and 2010 (Table 1) indicates that 430,374 more erasures occurred in 2010 than in 2009 across the grades and subject areas, a 20.5% increase. The total numbers of erasures increased in grades 3, 4, 7, and 8 and decreased in grades 5 and 6 for 2010 from 2009. The percentages of erasures types, however, have remained fairly similar across the two administrations with a slight

increase of WTR and a decrease of Wrong to Wrong (WTW) across all grades. Table 2 shows the total erasures and percentage of each change by subject area for 2009 and 2010, respectively. As was the case in 2009, a slightly higher percentage of WTR erasures occurred in LAL followed by mathematics, and science. Table 1: Erasures by Grade 2009

Table 3 shows the erasure types by subject area and grade. The total numbers of erasures increased from 2009 to 2010 across most grades and subject areas except for grades 5, 6, and 8 LAL. Of the total erasures, the highest percentage of WTR erasures in LAL occurred in grade 8 (63.17%). For math, the highest percentage of the WTR erasures occurred in grade 3 (66.99%) and for science in grade 8 (51.38%).

Aggregate School Erasure Rates The state mean WTR erasure rate per student was derived by dividing the total number of WTR erasures by the total number of students in the state. Similarly, a school’s WTR erasure rate was derived by dividing the total number of erasures by the total number of students in the school, irrespective of grade and subject area. Table 5 displays the average number of WTR erasures per student for schools with erasure rates above or below two standard deviations of the state mean. The statewide WTR erasure rate per student for schools with more than 30 students was 2.43 with a standard deviation of 0.75. Erasure rates two standard deviations above the state mean indicate higher than expected erasures; whereas erasure rates two standard deviations below the state mean imply fewer erasures than might be expected. Please note: The selection of two standard deviations was somewhat arbitrary and not intended to indicate that the WTR rate at these schools was statistically different from the statewide mean WTR rate. The primary purpose of these analyses was simply a screening device to identify schools with more than or less than the expected number of WTR erasures. The expectation was that additional investigations would be implemented at schools with excessive WTR erasures as

5


defined by the NJ DOE. These analyses were not designed to conclude that inappropriate activities had or had not occurred. A comparison of Table 5 with 2009 results reveals that some schools that were flagged for high erasure rates measured by the mean WTR erasures per student in 2009 were also flagged for high erasure rates in 2010. For example, ABINGTON AVE in Table 5 had the highest erasure rate (mean erasures=11.70) in 2010 and was also flagged for a high erasure rate in 2009 (mean erasures=6.79).

The following observations can be made from the Tables in Part 1: 1. Overall, about 20.5% more erasures occurred in 2010 compared to 2009. Despite the increase of total erasures, the percentages of different types of erasures were very similar across grades, subject areas, and DFGs between the two administrations. 2. At aggregate level (Table 5), 17 schools that were flagged for high erasure rates in 2010 were also flagged in 2009. Nine of the 17 schools were also flagged for high erasure rates in one or more grades in 2010 (Tables 7-12). 3. The school Abington Ave was flagged for a high erasure rate at the aggregate level (Table 5) as well as at all grade levels (Table 7-12) in 2010.

13


Part 2. School Erasures and Person-Fit Analyses by Grade and Subject Part 2 provides WTR erasure rates per student on operational tests by grade and subject area (LAL, mathematics, and science) for schools with 30 or more examinees and compares the schools with high erasure rates against person-fit measures. The mean number of WTR erasures per student in a given grade for a given subject area was calculated by dividing the total number of WTR erasures by the total number of students in the given grade for the subject area. The schools that were flagged for high WTR erasure rates in a given grade/subject area were then compared against the schools that were flagged for poor person-fit rates. If the two approaches flagged the same schools it may be an indication of test irregularity. The person-fit analysis is an item response theory (IRT) based approach where the unexpected behaviors of a student can be detected given his/her ability. The four measures that were employed here included InFit, OutFit, Standardized InFit, and Standardized OutFit. The InFit measures unexpected behavior affecting responses to items targeted to the student's ability level, OutFit measures unexpected behavior of a student on items far from the person's ability level; and standardized InFit and OutFit detects the statistical probability of the mean-square statistics occurring by chance when the data fit the Rasch model (Linacre, 2006). For example, if an average student were to answer an average difficulty item incorrectly the associated InFit statistic would likely be outside of the targeted range described below; whereas, if the same average student answered extremely difficult item correctly the accompanying OutFit statistics would again be outside of the expected range. A student’s response pattern was flagged for abnormality if the InFit and OutFit values were outside the range of .7 and 1.3. It is expected that the InFit and OutFit values are close to 1.0. The values greater than 1.0 show poor model fit indicating variance in the data not explained by the model. Whereas, the values less than 1.0 show overfit indicating that the model predicts the data too well causing inflated statistics. Since the standardized InFit (ZIn) and OutFit (ZOut) values follow normal distribution the 95% confidence interval (±1.96~±2.0) was used to flag a student with abnormal response pattern. The negative standardized values indicate overfit. For a more detailed explanation about the statistics readers are advised to refer to WINSTEPS User’s Guide (Linacre, 2006). The person fit rates for InFit, OutFit, ZInFit, and ZOutFit for each grade and subject area of a school were derived separately by dividing total number of students flagged from each of the criterion above by the total number of students in the given grade and subject area of a school. Table 13 provides the mean, standard deviation, and values for two standard deviations above and below the mean WTR erasure rates for the operational tests in statewide LAL grades. The WTR erasure rates per student were derived using the same procedure described in Part 1, except in this case only erasures on the operational items were analyzed.

Table 13: Descriptive Statistics by Grade Level in Lang. Arts Literacy – Operational Only Grade Mean WTR Standard 2 SD Above 2 SD Erasure Rate Deviation Mean Below Mean 0.40 0.29 0.97 -0.17 3 0.49 0.31 1.11 -0.12 4 0.66 0.33 1.32 0.00 5 0.86 0.47 1.80 -0.09 6 0.98 0.32 1.62 0.34 7 1.13 0.45 2.03 0.22 8

Tables 14-19 provide list of schools flagged for WTR erasure rates per student from the two standard deviation criteria and the associated poor person-fit flags for the schools. A “1� in the InFit, OutFit, ZIn, or ZOut columns indicates that the school was flagged for a poor-fit rate two standard deviation or above the state mean for the measures. For example, the first school in Table 14 (Franklin E.S.) was flagged for a high erasure rate on the grade 3 operational LAL test; however, it was not flagged for poor person-fit rate from any of the measures.

Similarly, Table 20 provides means, standard deviations, and values for two standard deviations above and below the statewide mean WTR erasure rate for the operational tests in mathematics. Tables 21-26 provide lists of schools flagged from the two standard deviation criteria and the associated poor person-fit flag for the school. Finally, Table 27 provides the statewide means, standard deviations, and values for two standard deviations above and below the statewide mean WTR erasure rate for the operational tests in science and Tables 28-29 provide lists of schools flagged from the two standard deviation criteria and the associated poor person-fit flag for the school.

The following observations can be made from the Tables in Part 2: 1. The erasures analysis results from Part 2 (Tables 14-19, 21-26, and 28-29) which lists schools with high WTR erasure rates and associated poor person-fit flag by grade for LAL, mathematics, and science shows that the number of schools flagged for high erasure rates are higher in lower grades (grades 3-5) in all subject areas. The school Abington Ave was the only one flagged for high WTR erasure rates for all grades and subject areas.

2. When comparing schools that were flagged for high erasure rates with the schools flagged for high poor person-fit rates, at least 49 schools across grades and subject areas were flagged from both approaches. However, the schools with the highest WTR erasure rates per student were not necessarily flagged for high person-fit rates. For example, Franklin E.S. was flagged for the highest erasure rate but not for poor person-fit rate in grade 3 LAL.

3. Among the schools that were flagged for high erasure rates, at least 18 schools across grades and subject areas were also flagged from the multiple person-fit measures. However, no schools were flagged from all four measures (InFit, OutFit, Z-In, and Z-Out). 4. At least two schools in LAL and three schools in mathematics were flagged for high poor person-fit rates in multiple grades (Tables 14-19 and 21-26). 5. The percentage of schools by grade and subject flagged for poor person-fit among the schools flagged for high WTR erasures ranged from 7.7% in grade 8 science to 58.8% in grade 6 mathematics. The percentage range for LAL was 10.7% to 23.1%, for mathematics was 13.9% to 58.5%, and for science was 7.7% to 22.7%.
