In addition, the data could also be used to identify possible correspondences between some mobility behaviors and the predisposition to learn sustainable mobility concepts to foster attitude change. To meet these objectives, an ER on sustainable mobility was conducted and a questionnaire was given before and after the activity to 173 students from various schools between 5th grade of primary school and 1st year of compulsory secondary school (10–13 years old). The questionnaire was divided into two parts. The first part included social demographics questions (gender, family members, place of residence) and mobility habits (number of cars in the family, bus use, cycling). The second part included questions related to sustainable mobility topics with 14 items. Data was collected between December 2022 and February 2023.

The recognition of the role of education as a key factor for sustainable development and sustainable mobility has been growing. Therefore, the development of training schemes aimed at sustainable mobility education as a tool for a better future for the generations to come is of fundamental importance. This study analyses the factors affecting the adoption of the ClassCraft platform in activities related to sustainable mobility. The proposed experience involved children aged 10–11 years old, a total of 75 pupils. This experience was the basis for analyzing the pupils' perception of the gamification-based methodology. A mixed method has been used, combining qualitative results from a Focus Group (FG) with 6 students, and quantitative results through a questionnaire based on the Technology Acceptance Model (TAM) with all the 75 students. The results reflect that all students consider this methodology as an opportunity for a change in the school experience to make classroom activities more enjoyable. Our research contributes to the application of a mixed methods approach that addresses an educational challenge, considering the voice of the children when applying new teaching–learning strategies.

In the 94% of the studied samples, the porosity in which crack nucleation originates is at the surface or adjacent to the surface. The threshold stress intensity factor amplitude and the limit of fatigue have been calculated following the classical models of parameterization of defects. A new set of samples were prepared by machining the surface slightly, in order to conserve the microstructure, and the fatigue behavior at low level of stress was improved. All the samples were produced in molds with the final shape by HPDC process, which allowed a realistic study of the surface effect and the influence of grain size variation from the edge to the center of the samples.

There is an industrial interest in the use of heat treatments in order to increase the elongation before failure of the alloy. This paper aims to correlate the results of tensile test of heat treated specimens with small punch tests (SPT’s). It is also intended to find out if the different characteristic values of such tests for different mechanical properties are sensitive enough to detect changes produced by heat treatments or injection process parameters and if the correlation factors are sufficiently stable. In addition, this study is also focused on the validation of the applicability of such miniature tests for high pressure die casting magnesium alloys, since this process introduces a significant number of defects and thus a variability of the mechanical properties is expected.
