Faced with the change to the virtual teaching modality due to the COVID-19 pandemic, teachers have the obligation to prepare competent, critical and autonomous professionals who can respond to various situations and face challenges once they occupy their workspace, all this within the framework of virtual teaching. Assessment is one of the aspects that changed the most with this transition to virtual mode, and although learning platforms such as Moodle or Blackboard have different options for creating questions, sometimes these are not enough, especially in engineering and science courses. That is why it is required to use programs such as Wiris, which provides various tools for formulating questions. Considering this, this article aims to describe the main tools that Wiris offers in formulating questions and designing evaluations, in addition to showing the effectiveness of automatic fe...

The Geostatistics provides effective tools for the solution of many problems of engineering in which the location in the space of the variable under study is considered, based on definitions of mathematics that provide the necessary foundation for its application. In particular, the Geostatistics are applied in the spatial estimation of the recoverable reserves of mineral deposits. The geostatistical methods that are used in the estimation of mineral deposits are implemented in industrial software and consider the evaluation of the complex geological structure, but these softwares only display the obtained results with an input data and do not exhibit the concepts thatthey use during the process or the methodology of its application. This happens particularly with the Kriging method, which is based on the assumption of strict stationarity, taking into account changes in the mean and loca...
