SoundHunters

SoundHunters is an arcade-inspired game that teaches the sounds of Plains Cree (nehiyawewin). Deer descend with text attached to them as the player hears a sound on repeat. It’s the player’s job to shoot the deer whose text is associated with the given sound.

There are three versions of this game:

  1. a basic Plains Cree version,
  2. an adaptive Plains Cree version that personalizes the game play to the player, and
  3. a version that will teach the sounds of Southern Michif, a language spoken by some  Métis people. This version is currently under development

CreeTutor: A System to Help People Learn nehiyawewin (Plains Cree)

The CreeTutor Project aims to teach learners nehiyawewin (Y-dialect Cree). This website will provide computer assisted learning material for adults to promote their aural fluency in the language.

Currently, most of the websites available to Cree learners are largely focused on providing resources rather than providing instruction, they are also generally underfunded and not user-friendly. The website we are developing hopes to provide instruction to users through mini games as well as exposure through animations, recorded stories, and other activities.

Cree NLP Project

Plains Cree is a low resource language, Indigenous to Canada. This language is at risk of being lost so we have collected a corpus of language materials to enable the creation of language technologies.

violin_plot_ngram_ab.v1

The developed corpus consists of different forms of data such as videos, audio, and text from various resources like Facebook, Youtube, Cree blogs, and educational websites. It also includes stories from community members. In addition to these base resources, the corpus contains English-Cree aligned texts.

This corpus will help enable the application of downstream natural language processing tasks, such as language models.

Detecting Negative Language Transfer

This project identifies structural writing errors related to language transfer in the texts written by English language learners. It does this using machine learning and language models to represent the learners’ first languages and English grammars. It then provides learners with targeted feedback based on those errors.

This project has two parts. Identifying negative language transfer (NLT) and providing feedback to learners based on their negative language transfer.

To identify NLT in learner writing, models are used to identify which incorrect utterance structure is more prevalent for a particular population of learners and whether there is any indication that these incorrect utterances may be influenced by the English language learner’s first language. At present, we are trying to identify NLT in the writing of speakers of Chinese and Persian (Farsi) as a first language. 

To build these models, we first had to create datasets that could be used to train them. These datasets can also be used to test models that detect grammatical errors that are due to negative language transfer. 

We developed a Google Docs plug-in using these models. The plug-in gives learners targeted feedback to help them understand their grammatical errors when the error is a result of their borrowing grammatical structures from their first language. We are about to start a study of how Chinese learners of English respond to this support.

Adaptive Literacy in Corrections

This project aims to support the development of incarcerated persons’ literacy skills. Learner modelling will capture literacy-contributing skills and be used to personalize each user’s learning experience.

Education in corrections presents unique challenges for learners, facilitators of programming, and correctional staff. Adaptive learning technology has the potential to support the learning of incarcerated persons. This application will use machine learning to make appropriate adaptations for learners based on assessments of their knowledge and behaviors.

Tier 3 CS Vocabulary

This project aims to create a list of advanced vocabulary that are specific to computer science using tools and techniques from natural language processing.

To support computer-science education efforts and English learners, we are creating a list of the most-used advanced vocabulary in computer science. Like other word lists that cover more general academic vocabulary, this list could be used to support English for specific-purposes learning when students plan to pursue computer-science degrees. It could also be used by computer-science instructors to better support these students.

Going beyond the creation of this list, we aim to analyze the usage and adoption of the identified vocabulary in student discourse.

Online Learning

PeppeR Analytics

PeppeR Analytics seeks to improve and support the online learning experience of PeppeR forum by mining the social relationships, visualizing the analytics of student usage and linguistics data, updating visualization libraries, recommending posts of interest for students and developing new analytics such as online class involvement, connectedness and learning support. 

Boy studying at home. online education concept.

Through applying Natural Language Processing (NLP) and Human Machine Interaction (HCI) techniques, forum posts, build topic models, and conduct sentiment analysis, is analyzed and visualized. On the other hand, a think-aloud approach is used to identify areas for improvement in the student’s learning experience. Collaborative filtering and content-based filtering is also used to build recommender systems.

Learning Analytics to Support Collaborative Learning

This project aims to improve and support the collaborative learning experiences of students through the use of analytics by helping students or instructors to understand how people are working together and recommending materials or posts that should be of interest to a specific user.

When instructors have access to analytics, the goal is to support their monitoring of course activities so that they can adjust them to ensure that their desired pedagogical design is enacted.

ICTs for Indigenous Women in Latin America and Canada

The goal of this Partnership Development Grant project is to create an international partnership of individuals and institutions with expertise in ICTs, gender, communication, and Indigenous ways of knowing in order to support of Indigenous women’s efforts to develop gender-responsive ICTs for their specific priorities.

We aim to accomplish the development of a sustained partnership of individuals, CSOs and institutions committed to supporting Indigenous women’s efforts, as well as provide mentoring and training opportunities for Indigenous women. Furthermore, we will conduct research with Indigenous women’s CSOs in Canada and Latin America to co-develop and recommend ICT strategies and solutions to the priority areas.  The project will produce a number of tangible deliverables, such as training modules for Indigenous CSOs in the 3 areas, strategies, and solutions.

Augmented Reality Use in Education

This project conducts a quantitative analysis to measure the extent of the augmented reality techniques’ impact on education.

In this project, we conducted a meta-analysis of quantitative research papers (journals and proceedings in the past ten years) that were included in major databases. The main purpose of this meta-analysis study was to analyze the impact of AR on users’ learning outcomes in both informal and formal learning contexts.

Eye-gaze Learning Analytics to Support Online Learning

This project aims to improve and support the online learning experiences of students through the use of eye-gaze analytics. These analytics will help students or instructors understand people’s attention patterns and information-seeking strategies.

In the sub-projects, we model users’ (e.g., students, expert) learning patterns using detailed eye-tracking information (e.g., gaze, pupil, blink) in different learning scenarios including writing modification, RSVP reading, and Gamed-based language learning.  The comparison between eye-gaze behaviours and learning performance offers insights into learning strategies and provides the potential to design adaptive learning support that accounts for these strategies.
