| Descripción : | This investigation arises from the establishment of difficulties in the work with graphs that they require to the time like variable. The confusion of the axis of time with a distance axis or the identification of the graph of the trajectory of the moving body whit the graph of whole range in the time among other alternative conception is observed frequently in the student productions. On the base of these evidence one sets out to investigate in the obstacles to construct, to interpret and to work with graphs of variation phenomena that they require to the time like variable. The work corresponds with the phase of previous analysis of a didactic engineering and recognizes that the conceptual systems, even most abstract, are organized on the base of conceptual metaphors, metaphors that help or prevent the work with the mathematical objects. The historical-eptemologic investigation followed elements of visualization of phenomena of variation in the time, as well as, the conception of the time notion. The cognitive studies start the analysis of student productions and of the determination of his representations and daily experiences of time. The curricular speech on the handling of graphs that sets out for the work of the classroom, it is documented with given text revision of study to the schools by the Government of Chile. The interpretation of the study is to identify the conceptual metaphors necessary to interpret the graphs present distance-time and those daily metaphors in the students, whit the purpose of establishing obstacles for the work with this type of graphs. Among other results they report meaning and diverse repetitions for the time and stared that the construction and interpretation of graphical distance – time is not possible without a frame of meaning and representations shared by the communities of specialists an the educative community. |
