FORMA3D – AN EDUCATIONAL PROGRAM FOR THE QUALIFICATION OF TECHNICAL PERSON INVOLVED WITH COORDINATE METROLOGY IN BRAZIL

The fast dissemination of coordinate metrology in Brazil has not been followed by the necessary qualification of human resources. Because of its flexibility, complexity and great integration with the whole manufacturing system, Coordinate metrology demands an in depth qualification of the technical person. This paper describes an educational program developed by professionals from Universities and Industries in Brazil for the qualification of technical person involved with coordinate metrology. The program, called FORMA3D, has been active since 2004 with more than 100 3D Metrologists graduated. The motivations, the technical background, the pedagogical structure and the preliminary results are related in this paper.

SOME LATIN-AMERICAN EXPERIENCES CONCERNING TEACHING OF CHEMICAL METROLOGY

Some acquired experiences concerning the teaching of Chemical Metrology in Latin-America for almost fifteen years are presented. They include postgraduate and undergraduate activities developed in seven countries of this continent. The combination of theoretic and practical activities and the sequence of learning from metrological, statistical and chemometrical backgrounds up to practical activities in personal computers are basic and motivate the learning process. Care is taken in order to promote the metrological approach and thinking in Analytical Chemistry. The learning of computing techniques plays an important role, combining graphic and numerical techniques for data analysis. The role of examples during the teaching process is analyzed and recognized. The introduction of a general model of errors permits to approach different topics on a metrological basis. Similarly, linking of performance characteristics of analytical procedures and validation concepts is essential. The understanding of traceability prepares students for organizational actions. Proper understanding of interlaboratory studies is attained on a practical basis. The metrological approach of uncertainty based on the Theory of Errors permits to develop the topic. A better comprehension of written standards is obtained from practical examples. Undergraduate students acquire a basic metrological knowledge very well. Recommendations for undergraduate and postgraduate programs are pointed out.

REMOTE VERSUS CLASSICAL LABORATORY IN ELECTRONIC MEASUREMENTS TEACHING - EFFECTIVENESS TESTING

Considering importance of practical experience as a crucial step in effective transfer of knowledge to learner in electric measurements and other technical fields, paper caries out research results of effectiveness testing on remote laboratory developed at University of Sannio, Italy. Although remote laboratories are spreading among universities and educational institutions very fast because of their advantages in setup, price and accessibility actual effectiveness of this laboratories comparing to classical is still unknown. Two groups of students of the electric and electronic measurement courses have been chosen to test the effectiveness of remote laboratory comparing to classical one through specially designed experiment. They were executing both, hands-on and remote experiment. Obtained examination results and the learning process of those students have been analyzed and compared with those obtained by group of students of traditional teaching. Some surveys has also be carried out in order to obtain a feedback on effective usability, benefits and helpfulness of the remote measurement laboratory, but also it’s weakness and issues to be improved or investigated in the future.

AN INTERACTIVE TOOL FOR TEACHING METROLOGY

This project was meant to be a study supporting material different from the current available ones to graduating students and technicians in the metrology field. Its setup was based on personal experiences from its elaborators. When deciding the contents and formatting of this project, it was agreed that it should contain the subjects: metrology history and terminology, number treatments, measurements, calibration and uncertainty estimates. It should also point out notions of nanotechnology. We were careful not to turn this project into a simple transcription of study notes from textbooks to a computer screen, so definitions and concepts a bit more difficult to understand were reviewed and illustrated with animations and / or interactive exercises. A growing order of difficulties was obeyed, beginning with its supporting chapter and concluding with some complex calculation of uncertainty measurements. Accessing it from remote locations will be possible in a near future. During its elaboration, this project was positively evaluated by several collaborators from different fields, from engineering students to technicians. The users were pleased with its contents and formatting what gave us the confidence that we were innovative and in the right track to become a reference supporting material for metrology studying and researching.

TRAINING ON BASICS FOR INDUSTRIAL METROLOGY BY INTEGRATION OF WORK AND LEARNING IN THE PROJECT MESS-IN

For the correct performing of measurement tasks, the operator needs a lot of knowledge in many fields. As so far there is no education for becoming a metrologist in Germany, in the project Mess-iN a comprehensive training for advanced vocational education in metrology was developed.The course consists of two phases: A learning phase focusing on the gathering of knowledge and a project phase focusing on the transfer of knowledge into daily practice. The course is accompanied by a tutor. The imparting of knowledge in the first phase is designed as Blended Learning. Web based learning modules are combined with workshops to provide both a high degree of freedom in learning and the possibility for hands-on-training and direct communication. During the project phase the participants work on a real metrological problem. Thus lack of knowledge or understanding will show up early and can easily be resolved. Additionally, by working on the project the participant is encouraged to communicate his newly gained competencies to his colleagues. Therefore he acts as a disseminator of knowledge. By that integration of learning into working, the course Mess-iN offers an efficient education for metrology and enhances the long term success of the training.
