Appropriation of the Concept of the Logical Quantifiers by the Teachers and Pipuls from the Secondary of the Goma Town in the D.R.Congo

This work aims the assessment of the level of appropriation of the notion of logical quantifiers by the math teachers and the pupils from Goma city. Indeed, after a mathematical logic course and several opportunities of use of the logical quantifiers, the finalists of the math department of the Educational Superior Institutes are supposed to use the logical quantifiers correctly and well to interpret the propositions formulated with the help of the logical quantifiers. Is this still the case The experience of the land seems to sustain the opposite. It is what caused the present reflection in order to consist of the state of things and to propose some tracks of solutions susceptible to improve the know-how and the know-how to make some teachers of Mathematical of the city of Goma in the understanding of the mathematical statements. To reach this objective, we used a questionnaire. This questionnaire has been addressed to a sample of 96 teachers, of which 21 stepped up and 75 bachelors, qualified in math teaching and to 400 pupils of the secondary of the city of Goma. /it was about the use of logical quantifiers, the research of the negation and the interpretation of the logical propositions formulated with the help of logical quantifiers. The data descended of the investigation have been presented in pictures to double entry and have been translated as percentages. The studied phenomena have been considered and have been put in evidence by the importance of their respective percentages. The results of this work put in evidence, among the teachers of Mathematical and the pupils of the Secondary of the city of Goma, a bad use of the logical quantifiers and a bad interpretation of the propositions formulated with the help of the logical quantifiers. To the basis of this bad use of the logical quantifiers and the bad interpretation of the propositions quantified is the non mastery of the notion of logical quantifiers and the notions of Mathematical logic by the teachers of mathematical of the city of Goma.
