GeOrder Simulator as Provocator of Semiotic Representations for Statistics Learning in STEM

A realistic situation, proposed from data generated within the GeOrder Simulator to elicit the statistical reasoning

“…In learning statistics, students usually do not collect data when solving a problem. They analyze static information, from a small sample, provided by textbooks in tables and graphs, so concepts such as sampling and randomness are not learned; the process of experimentation and identification of variables and processes is left out, reducing the interpretation and analysis necessary for statistical reasoning [14] .…”

“…Performance and price of fuel is consulted at the moment. Source [14] . Company Shipping policies “Envilocal” $ 10.00 per kilogram plus $ 25.00 per shipping.…”

“…From that, the cost of each of the two companies and the cost of their own shipping system are compared, following the specifications of Table 1 . The costs shown in Table 1 have been taken from [14] . It should be noted that for the cost of the own delivery system should be added the salary, benefits, vehicle insurance and fuel costs.…”

“…For example, by including visualizations or figures from numerical elements a set of data, the students would establish a connection between numerical and graphical semiotic representation registers for the same information. See [14] for previous work presenting a software for help in this aspect.…”

“…This scenario is presented to a Logistic and Transport Engineering students group to address the concepts of central tendency and spread measurement, taking advantage of the geospatial context to ease to the students the Statistics learning process. To support this aim, and in order to enhance the learning experience of the students group, it is developed the software GeOrder Simulator [14] .…”
