Desenvolvimento e avaliação de um programa computacional para o ensino à distância de tecnologia de aplicação de agroquímicos

Abstract

Distance learning presents great potential for mitigating field problems on pesticide spraying technology. This methodology does not intend to replace live trainings, but complement them, especially considering the importance of field practices for this activity. Thus, due to the lack of teaching material about pesticide spraying technology and the increasing availability of distance learning, this study developed and evaluated a computer program for distance learning of the theory of pesticide spraying technology, using the tools of information technology. The modules comprising the course, named Pulverizar , were: (1) Basic concepts, (2) What affects spraying?, (3) Equipment, (4) Spraying nozzles, (5) Sprayer calibration, (6) Aircraft spraying, (7) Chemigation, (8) Physical-chemical properties, (9) Formulations, (10) Adjuvants, (11) Water quality, and (12) Adequate use of pesticides. The program was made available to the public on July 1st 2008, hosted at the site www.pulverizar.iciag.ufu.br, and was simple, robust and practical on the complementation of traditional teaching for the education of professionals in Agricultural Sciences. The system allows the access to the contents to professionals interested on the topic anywhere, at any time, and no cost. Mastering the pesticide spraying technology by people involved on agricultural production can be facilitated by the program Pulverizar, which was well accepted in its initial evaluation.
