Gen Ed Project Analysis Spring 2010

34 faculty provided 2410 data points from 810 students. This compare favorably with past semesters, where 26 faculty provided 1091 data points from 332 students last spring and 46 faculty provided 2653 data points for 677 students in Fall 2009.

Multiple Views of Data

First, the data are presented, in Multiple Views of Spring 2010 data, as average scores versus each GenEd objective, numbered 1-19. The various views contrast male/female, CTE/AS, ethnicity, campus, and GPA.

Finally, histograms of GPA and credit-hours earned are presented.

Time-series Evaluation of Scores

The following text refers to Gen Ed Project Results - Spring 2010:

The number of credit-hours earned for each of the students was associated with each score earned, then the student names were stripped out for anonymity by referring only to S-number in the data table. None of this identifiable information is present in any of the publically available data.

The time-series analysis is performed as follows. All of the data for one GenEd objective is plotted, one dot per student (y-axis is score 1,2,3 while the x-axis is the number of earned credit hours that student has at mid-semester). The scatterplot for the Spring 2010 GenEd objective 4b ("Determine a realistic answer (approximation) and qualify result") data is: The naive fit of these 308 points is shown on this graph (this graph has a negative slope indicating that students with more hours score lower!). To get confidence limits on the slope, we ran a resampling-with-replacement analysis 100,000 times on each plot (this means that all of the data points are placed in a "bag" and extracted randomly, plotted, and thrown back into the bag. Once 308 points are plotted (note that some are duplicated and some are omitted), the slope is recomputed. This allows us to compute a probability of positive slope for each GenEd objective.
