  We investigated the epistemological conceptions of the uruguayan Physics
teachers and future Physics teachers through the application of the CLASS test
(Colorado Learning Attitudes about Science Survey), one of the most accepted
instruments in the research community in Physics education. The results
obtained allow us to compare the attitudes and beliefs about science of both
groups and quantitatively evaluate the agreement or not with the conceptions of
experts in the field. First, we present a general screenshot of the responses
and then we identify categories in which there are significant similarities or
differences between the two groups studied and in turn with the reference of
the experts. The categories that show significant positive or negative
variations between the opinions of future teachers and teachers indicate the
areas where training is favorable or unfavorable. On the other hand, the areas
where the differences with the opinions of the experts are globally notorious
suggest that they should be strengthened. To get a more global perspective, we
also compare our results with those published in the literature. Finally, we
raise several questions that we think may favor further inquiries.
