In GPMS, students’ grades are analyzed to generate reports and statistics, and draw conclusions. Reports can be semester oriented or rubric oriented. In other words, a report is generated based on students’ grades in a certain semester or based on students’ grades spanning many semesters of acertain rubric.The grades statistics report is the first report in GPMS. It is a summary report that summarizes the grades of students. The report has the following statistics: lowest grade, highest grade, average grade, standard deviation, 5th percentiles, 25th percentiles, and final grade distributions. A percentile is a statistical measure that indicates the value below which a given percentage of observations in a group of observations falls. For example, if the 25th percentile of the final grade of students is 80, then 25% of students has a grade of 80 or less. Conversely, 75% of students has score better than 80. Figure 23 presents a screenshot of the grades statistics of spring 2016 grades of senior II. The first table in Figure 23 shows the list of grades and the second table shows statistics. For example, 95% of students achieved a final grade at or better than 19/40 in senior II, and 75% of students achieved a final grade at or better than 24/40. The coordinator can make use of these statistics in identifying problems and difficulties facing students.In addition to the summary report, GPMS is equipped with data mining component that analyzes grades of the rubric items. The results of these reports can be used to make decision such as which part of the rubric students should focus on in order to improve their final score. We have incorporated two data mining mechanism to analyze the data, namely, Association Rule Mining (ARM) and Decision Tree (DT). ARM is useful to associate fields together based on a population while DT can predict future grades. Both can help discover hidden patterns in the students’ grades; hence, uncover certain behavior of students in conducting senior activities. The implementation of ARM and DT is based on WEKA data mining software [9].
