Análise, desenho, desenvolvimento e implementação de um sistema de aplicações laboratoriais na Petromoc - desenho de um sistema de ensino de aritmética por computador

Abstract

The main objective of this work is to demonstrate, through a practical application, the use of computers in different areas. In this prespective two distinct sections were developed and are described below. PART I Because the use of computers in industry has increased substantially during the last decade, industries have identified the need for the development of computer systems in new application areas. In this context, the work presents the Design, Development and Implementation of a system for use in the laboratory of PETROMOC - E.E. The need to produce test reports on various petroleum product samples in the chemical laboratory is thus inevitable. The Analyst is forced to work in the laboratory for a long period of time, testing the samples and calculating through the standard ASTM procedure or through other standard procedures using various tables and graphs to obtain the values of the variables involved.

0 time lost between the completion of the test in the laboratory and obtaining the report, can be greatly reduced through the use of the computerized system developed here while eliminating the possibility of calculation errors. PART II Nowadays, computing has had a great impact on the sphere of economic and social development. In order to provide appropriate training to the next generations, it becomes necessary to introduce the use of computers in Education in Mozambique. With this idea in mind, the present work is an attempt to design an Arithmetic Instruction System for primary education. The software that will be developed later will allow students to learn number concepts, addition, subtraction, multiplication, and division operations, allowing them to learn the concepts and perform self-assessment at various levels. This system will be of great help to mathematics teachers in elementary school, since students trained by it will enjoy greater self-confidence. It should be noted that the System will be developed, tested, and the results presented separately. (TRADUÇÃO NOSSA)
