Interpreting the Benchmark Comparisons Report

To focus discussions about the importance of student engagement and guide institutional improvement efforts, NSSE created five Benchmarks of Effective Educational Practice: Level of Academic Challenge, Active and Collaborative Learning, Student-Faculty Interaction, Enriching Educational Experiences, and Supportive Campus Environment. This Benchmark Comparisons Report compares the performance of your institution with your selected peers or consortium. In addition, page 9 provides two other comparisons between your school and (a) above-average institutions with benchmarks in the top 50% of all NSSE institutions and (b) high-performing institutions with benchmarks in the top 10% of all NSSE institutions. These displays allow you to determine if the engagement of your typical student differs in a statistically significant, meaningful way from the average student in these comparison groups. More detailed information about how benchmarks are created can be found on the NSSE Web site at www.nsse.iub.edu/2008_Institutional_Report/.

Class and Sample Means are reported for first-year students and seniors. Institution- reported class ranks are used. All randomly selected students are included in these analyses. Students in targeted or locally administered oversamples are not included.

Mean The mean is the weightedarithmetic average of student level benchmark scores.

Benchmark Description & Survey Items A description of the benchmark and the individual items used in its creation are summarized.

Statistical Significance Benchmarks with mean differences that are larger than would be expected by chance alone are noted with one, two, or three asterisks, denoting one of three significance levels (p<.05, p< .01, and p<.001). The smaller the significance level, the smaller the likelihood that the difference is due to chance. Please note that statistical significance does not guarantee that the result is substantive or important. Large sample sizes (as with the NSSE project) tend to produce more statistically significant results even though the magnitude of mean differences may be inconsequential. It is recommended to consult effect sizes to judge the practical meaning of the results.

a See theNSSE Effect Size Interpretation Guideat www.nsse.iub.edu/html/effect_size_guide.cfm for additional information.

a Effect Size Effect size indicates the practical significance of the mean difference. It is calculated by dividing the mean difference by the pooled  . , an effect size of .2 is often considered small, .5 moderate, and .8 large. A positive sign indicates that your institution’s mean was greater, thus showing an affirmative result for the institution. A negative sign indicates the institution lags behind the comparison group, suggesting that the student behavior or institutional practice represented by the item may warrant attention.

Students learn more when they are intensely involved in their education and asked to think about what they are learning in different settings. Collaborating with others in solving problems or mastering difficult material prepares students for the messy, unscripted problems they will encounter daily during and after college.

Students learn firsthand how experts think about and solve practical problems by interacting with faculty members inside and outside the classroom. As a result, their teachers become role models, mentors, and guides for continuous, life-long learning.

NSSE 2008 Benchmark Comparisons With Highly Engaging Institutions

Interpreting the Top 10% and Top 50% Comparisons

This section of the NSSE Benchmark Comparisons report allows you to estimate the performance of your average student in relation to the average student attending two different institutional peer groups identified by NSSE for their high levels of student engagement: (a) those with benchmark scores placing them in the top 50% of all NSSE schools in 2008 and (b) a those with benchmark scores in the top 10% for 2008. These comparisons allow an institution to determine if their engagement of their students differs in significant, meaningful ways from these high performing peer groups.

NSSEville State CAN conclude... Š The average score for NSSEville State first-year students is slightly above (i.e., small positive effect size) that of the average student attending NSSE 2008 schools that scored in the top 50% on Level of Academic Challenge (LAC). Š The average NSSEville State first-year student is as engaged (i.e., not significantly different) as the average student attending NSSE 2008 schools that scored in the top 10% on Active and Collaborative Learning (ACL). Š It islikelythat NSSEville State is in the top 50% of all NSSE 2008 schools for first-year students on Level of a,b Academic Challenge (LAC) and Active and Collaborative Learning (ACL).

a NSSEville State CANNOT conclude ... Š NSSEville State is in the top half of all schools on the Student-Faculty Interaction (SFI) benchmark for first-year b students. Š NSSEville State is a "top ten percent" institution on Active and Collaborative Learning (ACL) for first-year b students.

For additional information on how to understand and use the Top 50% and Top 10% section of the benchmark report, see www.nsse.iub.edu/2008_Institutional_Report/.

a Precision-weighted means (produced by Hierarchical Linear Modeling) were used to determine the top 50% and top 10% institutions for each benchmark, separately for first-year and senior students. Using this method, benchmark scores of institutions with relatively large standard errors are adjusted substantially toward the grand mean of all students, while those with smaller standard errors receive smaller corrections. Thus, schools with less stable data, though they may have high scores, may not be identified among the top scorers.

b NSSE does not publish the names of the top 50% and top 10% institutions because of our commitment not to release individual school results and because our policy against the ranking of institutions.

a All statistics are weighted by gender, enrollment status, and institutional size. b Standard Deviation is a measure of the average amount the individual scores deviate from the mean of all the scores in the distribution. c The 95% confidence interval for the population mean it is equal to the sample mean plus/minus the product of 1.96 times the standard error of the mean. d A percentile is the point in the distribution of student-level benchmark scores at or below which a given percentage of benchmark scores fall. e Degrees of freedom used to compute the t-tests. Values vary for the total Ns due to weighting and the equal variance assumption. f Statistical significance represents the probability that the difference between the mean of your institution and that of the comparison group occurred by chance. g Effect size is calculated by subtracting the comparison group mean from the school mean, and dividing the result by the pooled standard deviation.

b Standard Deviation is a measure of the average amount the individual scores deviate from the mean of all the scores in the distribution. c The 95% confidence interval for the population mean it is equal to the sample mean plus/minus the product of 1.96 times the standard error of the mean. d A percentile is the point in the distribution of student-level benchmark scores at or below which a given percentage of benchmark scores fall.

f Statistical significance represents the probability that the difference between the mean of your institution and that of the comparison group occurred by chance.

g Effect size is calculated by subtracting the comparison group mean from the school mean, and dividing the result by the pooled standard deviation.
