This experiment is done by the module, Performance Predictor. The Performance Predictor tends to predict the future term marks based on the past term marks. For instance if the past term marks are available (grade 10's 1st 2nd and 3rd term and grade 11's 1st and 2nd term) then the last term (11's 3rd term) could be predicted. Please note that the predicted result is the Grade (A, B, C etc.) thus it's technically a classification. This task can be done for each subject as there are models which are built per subject. Number of classification techniques are used thus there exist many models per every subjects and the experiments below are tend to assess the models as well as trace the previously unknown or other significant information related to that subject in that school. There are more than a hundred different number of experiments (different combinations, per subject, per school, integrated school, difference in standardization, the term that is predicted [1st or 3rd etc.] and different models).
The experiment explores the subject Science and Technology in a particular school (School 1) and then among two schools (School 1 and School 2) via evaluating the models which predict 6th term in Ordinary Level (that is the 3rd term of the grade 11).
The outcomes are plotted in radar graphs below which are capable enough to store ample of information, in a single dimensional view. For more clarity, because this is the very first illustration, the result tables that are used to produce the graphs too are presented next to the respective radar plots. This case encompasses 48 different combinations which are nicely shown on the above radar graph, figure 1.
There are 4 different bins which are defined (refer section CLASS IMPLEMENTAION regarding the 'bins'), 3 ways of handling the missing values and 4 different algorithms result in those 48 combinations. The replacement techniques and algorithms are meaningfully depicted in the table.
This experiment is done by the module, Exam Comparator. The Exam Comparator tends to measure the standard of schools' examinations against the general examination conducted by the Sri Lankan government annually. It is applicable to grade 11's 3rd term and grade 13's 3rd term examinations, because the government conducts two general exams, one for Ordinary Level and one for Advanced Level.
As general examinations' results are not available to us at the moment, grade 11's 3rd term examinations are considered as dummy general examinations and grade 11's 2nd term examinations are considered as 3rd term examinations and compared against dummy general examinations to check whether they are agree on standards.
Jaccard Similarity is = 89.65517241379311
Sequence alignment similarity score = 93.59057807895084
According to explanation given in the chapter CLASS IMPLEMENATION under Exam Comparator Module, possible interpretations are,
Jaccard Similarity is = 79.3103448275862
Sequence alignment similarity score = 89.90365739269382
According to explanation given in the chapter CLASS IMPLEMENATION under Exam Comparator Module, one possible interpretation would be,
