GARBANZO LEON, Jaime  and  LARA MORALES, Gustavo. Interacting differential leveling instructor (IIN) in Topographic Engineering: design, development and testing. Rev. Actual. Investig. Educ [online]. 2018, vol.18, n.1, pp.299-320. ISSN 1409-4703.  http://dx.doi.org/10.15517/aie.v18i1.31518.

This study is to show how a simulator for surveying engineering differential leveling (IIN) teaching was developed and tested, the IIN supports the learning of leveling equipment and measurement computations. Traditionally, Differential leveling (ND) teaching is carried out in the field and to one student at the time. Because of this situation, ND teaching is slow and students do not get enough practice. To help in the equipment readings and computations of ND, a web based simulator was created using JavaScript, PHP and MySQL and to store these data to further analyze them. Two surveying student groups were taken: a study group (which utilized the IIN) and a control group (which did not utilized IIN). Two types of evaluation were carried out: a students’ opinion survey about the simulator and a comparison between the first field practice results of the control and the study group. The application got a high score in the survey and the study group performed better than the control group in the field practice. To conclude, the results suggest a better performance of the study group due to the simulator. However, a further study with more students have to be done to consolidate more significantly these results.
