E-LEARNING SYSTEM BASED ON SOCIAL NETWORK
FRAMEWORK. USING NLP IN EVALUATING OPEN QUESTIONS
Introduction. Electronic education in the twenty-first century has become almost
an obligatory attribute of any education. An attempt of e-learning system
implementation was taken during the developed of methodical testing and evaluation
system SMPR [1], which is an appendix to the course "Theory of decision-making"
[2]. The development of this system took place for several years with the involvement
of students of the third year of the faculty of cybernetics. In 2014, a web version of the
testing system was created, which was successfully applied during the exams
assessment. The next step in development was the development of a specific online
service for communication between teachers and students in the context of learning.
Most western universities have their own internal systems that allow some or even
most of the learning processes to be conducted through a global Internet network. It
helps students and teachers keep their time and gives them the opportunity to focus on
learning. Ukrainian universities do not have a centralized service with the necessary
functions, and, according to the authors, its introduction will improve the quality and
speed of education.
The computerized assessment of free text responses in recent years has become
essential for assessing a deep understanding of the material, which, according to most
educators and researchers, cannot be performed by simple testing.
"Computer Aided Evaluation (CAA) is a general term for using computers in
assessing student knowledge [3]." The idea of using computers to facilitate the learning
process has significantly changed the scope of evaluation systems. CAA studies began
in about 70's. CAA systems developed so far are able to evaluate only essays and short
text responses, such as multiple choice questions, short answer, choice / association
and visual identification [4]. Learning outcomes that include the ability to recall,
organize and integrate ideas, the ability to express themselves in writing and the ability
to interpret and apply data require less structured responses than those that can be
presented in the test. But it is this assessment that gives you the most complete
representation of knowledge.
