Comparison of GIFT, WikiQuiz, and QTI
Generally, here are the high level differences in the purpose for each type of format:

WikiQuiz [spec ]: text-based microformat to build quizzes. Ease of integration with Wikimedia resources, such as images and videos. Wikiversity does not have the functionality to track and compare student marks, like for a Learning Management System (LMS). Wikiversity primarily used for independent study or training to provide motivation and feedback on discovery and knowledge. The scores don't matter as much as learning something new.

GIFT [spec ]: The Moodle learning platform allows building quizzes via a graphical user interface (GUI), or uploading a GIFT format text file. The GUI does not allow for building quizzes collaboratively. The Moodle platform is designed for teachers testing students for scores and the platform has the functionality to rank and compare student scores. More functions for scoring and partial credit on responses.

QTI [spec ]: xml-based interoperability specification for IMS platforms, such as Educational Test Service (ETS) which administers the TOEFL and GRE large scale standardized tests. TOEFL and GRE scores are used for the school admission process in the United States. QTI is designed for storing and exchanging items independent of the authoring tool used to create them. It supports deployment of item banks across wide range of learning and assessment delivery systems; LMS lists 23 products on their website that use the QTI standard, including ETS and Canvas.

Below are comparisons of key features for each format. I try to give an example for each that captures specific capabilities for each format.

Platforms

 * WikiQuiz: Wikiversity
 * GIFT: Moodle
 * QTI: 23 learning providers that use QTI standard, including ETS (TOEFL, GRE).

Notable differences

 * Primary advantage for WikiQuiz is ease of adding images, videos, and sounds. GIFT requires a plugin and importing a zip file.
 * WikiQuiz allows for True and False to be correct; seems a bit odd.
 * WikiQuiz shows all feedback after submitting response (https://en.wikiversity.org/wiki/Help:Quiz#Inserting_feedback), while Moodle selectively shows feedback based on additional criteria.
 * QTI is xml-based and less human-readable than GIFT or WikiQuiz. Quiz authoring is via a GUI; QTI is just standardized format for large range of supported quiz authoring platforms.
 * QTI is designed for standardized exams for large groups. There is a shuffle option to change order of questions or list of words.

WikiQuiz does NOT have the following features, compared to Moodle:
 * Partial credit
 * Multiple responses required for full credit
 * Missing word, gives a list of options to select
 * Matching pairs
 * Essay

Moodle does NOT have the following features, compared to WikiQuiz:
 * Tabular responses (https://en.wikiversity.org/wiki/Help:Quiz#Tabular_response_type_with_radio_buttons)

Summary

 * Converting from WikiQuiz to GIFT seems doable, since WikiQuiz features mostly supported by GIFT.
 * For conversion of GIFT back to WikiQuiz could be challenging, because WikiQuiz doesn't support all GIFT features.
 * Converting between WikiQuiz/GIFT to and from QTI would be challenging.
 * While I can test GIFT files on Moodle and WikiQuiz on Wikiversity, I don't have access to a QTI platform for test.

Exercise to convert GIFT to QTI
Just as an example of converting GIFT to QTI. I tried to write a question in GIFT format for this simple example on the IMS QTI website.

Simple QTI example of quiz question with image.

I tried writing this example in the GIFT2QTI converter by Charles Severance.

First of all, the converter doesn't seem to support inserting an image yet, so I only addressed the text part. Here is the GIFT formatted quiz question:

This is the output of the conversion to QTI 1.2.1 (note that the latest version of QTI is 2.2), in xml:



Compare this to the source specified for the example:



As you can see, it's quite different. I will need to upload the converted file to a QTI-supported platform to see if it would be displayed the same.

Objectives for Next Week (Dec 12-16)

 * Familiarize with platforms for Moodle (GIFT), WikiQuiz, and QTI 2.2 supported platform
 * Understanding how quizzes are created and uploaded for each format.
 * May go through QTI simple examples, define the GIFT format for each and check what the conversion to QTI is the same.
