results. In several of the completed surveys, many participants expressed surprise at the level of detail and metric quality that was achieved by their models, which were
made using standard camera smartphones (Figure 6).
In general, the scoring system is appropriate for participants because it reduces subjectivity. The designed tests
have proven their effectiveness, and no complaints have
been received about them. Very few deliberate attempts at
fraud were detected, i.e., one case in which the results of the
first repetition were identical to those of the second repetition, which is impossible in practice, and another case in
which the 3D model was created with a reflex camera, which
allows the user to substantially improve the quality of the
photos and measurement results.

In addition to developing their 3D skills, the proposed
activities require students to engage in teamwork and promote their interest and curiosity in the search for solutions.
Both teachers and the project staff have agreed to emphasize the involvement of teams and originality when developing ideas to improve their results. Some examples of
this can be seen in Figure 7(a) and (b), where participants
managed to improve their photograph-taking process using
available resources.
Since the project's first edition, we have promoted participants' involvement in this challenge. With this objective
in mind, we have also created a specific award for the 3D
model that receives the most votes; this has been an excellent way to improve students' communication skills. This
award encourages participants to promote their own model
among their social circles using the aforementioned social
networks and many other media, thus indirectly enhancing the visibility of the championship itself. On our website
(http://www.d3mobile.es/vota_promo.php), we have compiled some of the most interesting proposals students have
used to request votes for their teams (e.g., https://youtu
.be/5UpTMGAqcRE).
Teachers are also encouraged to share the successes of
their students within their communities and in the local

press (e.g., http://d3mobile.es/hallfame.php) as a way to
recognize student efforts and also promote the visibility of
D3MOBILE. In many cases, not only teachers but also the
governmental entities of these countries are engaged in the
process of student recognition (e.g., the Ministry of Education of Ecuador, https://educacion.gob.ec/unidad-educativafiscomisonal-calasanz-de-loja-alcanzo-el-subcampeonatoen-mundial-de-diseno-3d/).

compared to those of students
in previous school years, taught
using only standard lecture instruction. In their opinion, overall
student involvement was remarkable, and it was particularly
notable for students who had been observed to have had poor
group interactions in other circumstances.
The project attempts to encourage students to approach
science from a more practical and less theoretical perspective by integrating different challenges using mobile devices
with which they are familiar. Based on the surveys received,
we believe the project has met its initial objectives.
More specifically, the program has encouraged future
students to pursue vocations in the field of geomatics by
showing them the diverse possibilities of this specialty in
