# Comparative Study of Moodle Plugins to Facilitate the Adoption of Computer-Based Assessments
## 5 Results and Discussion  
In this section, we compare the most important plugins that can be used to import questions into Moodle with FastTest PlugIn. The plugins were selected based on the literature review presented in Section 2.3. They are compared based on the question types that they provide, the available languages and the other features: installation in Moodle, operating system, creation of parameterised questions, commercial software requirements, written tests, gamification possibilities, and use of images. Table 5 shows the question types supported by each plugin. FastTest PlugIn, Moodle2 Word and VLEtools.com can handle a large number of different types of question. It should be noted that numerical questions can be entered in FastTest PlugIn via a Cloze question. The comparison shows how FastTest PlugIn is the only plugin that allows including all the question types considered in this paper. Although calculated questions cannot be directly used in FastTest PlugIn, these questions can be using Excel functions created using Excel functions due to FastTest PlugIn is a spreadsheet plugin. This is an advantage compared to the rest of the plugins of the comparison that do not include this type of questions. Therefore, FastTest PlugIn mitigated the detected limitations about the question types that the Moodle plugins for importing questions provides. Figure 8: Example of 10 MCQ questions for gaming activities created using FastTest PlugIn. Figure 7: Interfaces in Cauchy App: (**a**) main interface; (**b**) example question with text only; (**c**) example question with an image in the statement; (**d**) example question based on formulas; and (**e**) ranking interface. Table 6 shows the available languages for the four studied plugins. FastTest PlugIn stands above the rest as it includes all the languages supported by Google Translate, and; the user can personalise the text displayed on all the buttons and drop-down menus. Using the option \"Custom Dictionary\", FastTest PlugIn can be translated into any language supported by Google(r) Translate. Therefore, FastTest PlugIn provides the same languages and translation functionalities available by the other compared plugins: only VLEtools.com provides the same, the other plugins present less languages and functionalities. Table 7 shows a comparison of the other important features of the plugins. Moodle2 Word is the only plugin that needs to be installed in Moodle. This may be inconvenient, as only a Moodle administrator can install this type of plugin. The rest of the plugins do not require installation in Moodle. With regard to the operating system, Moodle2 Word, Question Machine and FastTest PlugIn are compatible with Microsoft(r) Windows, while VLEtools.com is compatible with all operating systems. FastTest PlugIn is not fully compatible with macOS (depending on the version, not all the functionalities are available). A version of Question Machine that is compatible with macOS is under development. FastTest PlugIn is the only one that allows for the creation of parameterised questions. Since it is based on an Excel spreadsheet, parameterised questions can be easily created using formulas. It should be highlighted that although Moodle Cloze Generator is a spreadsheet plugin too, it does not include this functionality. On the one hand, FastTest PlugIn, Moodle Cloze Generator and Moodle2 Word require commercial software: Microsoft(r) Excel for FastTest PlugIn and Moodle Cloze Generator, Microsoft(r) Word for Moodle2 Word. On the other hand, VLEtools.com and Question Machine do not require commercial software. However, due to the widespread use of the Microsoft(r) Office package all over the world,
