# Post-Digital Learning for Rural Development: A Case Study of _Open Biotec_ MOOCs in Colombia
## 3 Results and Discussion
### MOOCs Description  
_Open Biotec_ is expected to be a regional platform for virtual learning on biotechnology in a didactic environment with a simple language and open to all audiences. The user platform works under the WordPress system, and it communicates functionally with a Moodle platform for the hosting of the five MOOCs that comprise this route. The courses consist of four modules based on biotechnology and one corresponding to the topic of renewable energy. Figure 1 provides an impression of the introductory lesson in _Open Biotec_. All of them aimed at generating skills that allow the application of green processes in their environments, as shown in Table 3.  
Figure 2 shows the characteristics of the _Open Biotec_ MOOC courses and the user experience. The students are registered in the platform and begin an introductory module

Table 3: Description of the _Open Biotec_ MOOC courses. followed by a diagnostic test to assess their general knowledge in biotechnology, renewable energy, and bio-entrepreneurship, then they follow the five MOOCs created. Upon access to every course, the student finds the offer of activities that make up the instructional material, as described in Figure 3. The student begins with the Diagnostic Test, which corresponds to a questionnaire of 10 multiple-choice questions aimed at identifying the prior knowledge that the student has regarding the topics of the course. Then, the user accesses the Scorm Package, where, with the help of two avatars, the different themes of each course are explained interactively. There, it is possible to download additional information and access it through links to other web pages to complement the information. In case of doubts, there is a first forum (Question Forum) where the student can consult about the topics that have not been clear to receive feedback from the MOOC teacher. Subsequently, each course has a Practical Work, where the user experiences what has been learned.
