INTRODUCTION

In this part of my work, I'm going to deal with the problem, hypothesis, method and techniques, the scope of the topic, the choice and the interest of the subject, and finally the summary of the work.

1. The problem

Indeed, according to Congolese pedagogical system and the systems of most of the universities of other countries, the last day of the course is normally dedicated to evaluating students; and this evaluation is presented like a kind of questionnaire aiming at testing students. It is worth nothing that these evaluations are more often presented, as I mentioned earlier, like a kind of paper questionnaire; that is to say, teachers use to correct the sheets tests done by students.

Thus, At the University of Kinshasa in general and in the faculty of letters in particular, it may well be that there are more than five hundred students in some classes such as in the department of English business and Computer sciences. This situation has deeply allowed me to think about the way teachers deal with making the papers of students; according to enquiry, teachers mark the papers of students manually; as a result, teachers face many difficulties such as the slowness during the correction, the correction mistakes of papers, and the slowness during the transcription of grades of the students. Sometimes, that is due to the number of students which is high. It is for this reason in the search for the strategies of solving this problem; one question has particularly drawn my attention: is there any means to advocate in order to find a solution for the aforementioned problem? If yes, which one?

2. Hypothesis

A hypothesis is a provisional answer that is given to a question or raised problem. In this respect, the hypothesis of this study appears in the following way:

The manual system of evaluation as it is used by teachers is supposed to be ineffective for a quick decision making; for this reason, it would be very important to automate this system; that is to say, to put underway the use of computer system by putting available an expert system which can be capable to evaluate students.

3. Method and Techniques

a) method 

A method can be understood as a way which researchers use in order to lead their procedure at the end. Thus, in my search, I have used analytical method.

b) The techniques

Techniques are tools that the researchers use in order to collect data during the research process. Thus, in this search, we have used the following techniques:

- The interview technique: this technique helped me to obtain the qualitative data. So, this tool allowed me to interact with respondent face-to-face; sometimes on telephone.

- The technique of documentation: this technique helped me to consult books, journals, websites, as well as lecture notes to gather information about my work.
