# Moodle LMS Integration with Amazon Alexa: A Practical Experience
## 6 Conclusions and Future Work  
In this paper, we present the work done to build an Alexa skill for educational purposes, including its integration with Moodle, as response to our research question (RQ1), the development of which takes into consideration the existing scientific knowledge currently available. Our aspiration is to provide new scientific insight to help and guide researchers on future works of similar characteristics by exposing our successes and failures from the decisions and technical implementations taken along the development process.  
Contrary to the common approach taken by previous research on the field, we aimed to build our prototype of Alexa skill so that it would be immediately released and publicly accessible, while the current research available provides studies where prototypes are tested under controlled circumstances, mentioning conclusions about the future possibilities of releasing a production-ready version [33; 35].  
Nevertheless, we carried out a usability evaluation as well, to provide us with insight regarding the usage of the skill. With an initial survey, we were able to create participant profiles for better understanding of the feedback provided by the students in the following surveys and to further comprehend the results gathered from the analytical data extracted from the usage of the skill.  
For our research question (RQ2), and contrasting with some of the results we encountered on papers published in recent years, our findings indicate that Moodle is not a platform which currently provides the necessary tools for voice-content creation. Our findings indicate that, in order to create a voice experience with the use of Moodle data, there needs to be a middle layer that would process the data and produce sensible sentences that can be comprehend by users when spoken by a voice device. An alternative to build such missing layer of interoperability would be to implement enhancements that would allow Moodle to be ready for voice-content creation. As future lines of work, our team is considering how such enhancements could be brought to Moodle, either in the form of a Moodle plugin or as an additional application, similar to the Moodle mobile app, but for voice devices. Moreover, creating an additional platform that would bridge the gap between Moodle and voice devices could be an alternative.  
Besides voice-content creation, usability can be improved as well, providing a better experience for students when interacting with Moodle via voice instead of traditional visual interfaces. A new line of future work opens for researching how to improve the Moodle platform to be used via voice. A possible path could be to introduce a voice assistant within the Moodle mobile app, or perhaps create new plugins for existing web browsers to interact with Moodle via voice directly from the computer.  
Finally, we acknowledge the limitations of our Alexa skill, and we will continue working on functionality improvements in the upcoming developments of the skill. To enhance the limited set of commands understood by the skill, we aim to improve the skill to respond to any inquiry related to a course with no restrictions to what course that might be. Furthermore, the introduction of additional languages is on the scope for improvements. Currently the skill is only available in Spanish, but English could be very helpful for international students. Furthermore, we recognize the need to improve the methodology used when surveying participants regarding the experimentation and usability of innovative technology such as IPAs. For future studies, we perceive employing measurement tools as being beneficial for evaluation, for example, a System Usability Scale (SUS) [46] or User Experience Questionnaire (UEQ) [47].
