Introduction

Scholar retention is a supply of concern for all submit secondary faculties. A lot analysis has been carried out on the topic to seize a clearer understanding of the mitigating causes of e-learning drop out charges. Retention charges have been discovered to be correlated to admissions requirements.

With drop out charges of as much as 35% in some on-line educational establishments (http://www.ejel.org/volume-2/vol2-issue1/issue1-art13.htm, 2004), it’s crucial that the next areas of concern are addressed:

Query Mark’s essay grader element can present the identical quick suggestions tailor-made to particular person college evaluation wants. It’s a absolutely automated, touchless system that experiences scores not solely to the college however may even direct the suggestions to the scholar by way of an electronic mail response.

Statistical evaluation of composition has been carried out for over thirty years. LSA is confirmed to grade to 85% rater reliability in comparison with 80% rater reliability between two human judges. The pc is able to finishing the duty in considerably much less time (20-25 second elapsed ranking time common). People are influenced by many exterior elements of their ranking of essays; time out there to grade, reader bias, and many others.
