EdTech Projects
The following projects focus on utilizing the power of analytics to support teaching and learning experience.
Speaking participation detection using Raspberry Pi
Demo | Publication | Source code
Python, Dash
- A Raspberry Pi-based prototype to capture audio data from face-to-face group activity
- Analyzed the direction of arrival of captured audio to compute speaking time and turn-taking using python
- Developed an interactive dashboard for data visualization
CoTrack - Web application for monitoring collaboration behavior in classrooms
🏆 Best Demo Award at Learning Analytics and Knowledge (LAK2023) conference, Texas, USA (Core A rank)
Demo | Publication | Source code
Python , jQuery, MySQL, Etherpad, plotly, Google Speech-to-Text
Python Django app to collect multimodal learning data from group activities in classrooms
Voice activity detection to compute speaking time of individual in group activities in real-time
Google Speech-To-Text integration to process audio in real-time
A real-time dashboard visualizing group’s writing behavior, speaking participation, and speech content (in the form of word cloud)
Temporal window size identification for developing collaboration estimation model
Python , Scikit-learn, Matplotlib
Analyzed audio and log data gathered from Estonian classrooms during group activities
Explored use of different temporal window size (30s, 60s, 90s, 120s, 180s, 240s) to process features such as speaking time, turn-taking
Developed machine learning models to predict collaboration quality using audio and log data features processed with different window sizes
Across schools generalizability evaluation of machine learning models to predict collaboration quality
Python , Scikit-learn, Matplotlib
Analyzed audio, video and log data to develop machine learning models to predict collaboration quality in classroom settings during group activity
Used Random Forest algorithm to develop model and evaluated its generalizability with a different dataset collected from a different Estonian school
Web-Development Projects
I worked on the following projects as part of my web-developer role at Tallinn University.
TruestedUx
Python , Django, jQuery, Bootstrap
An application which allows assessment of trust aspect of technology usage.
Developed the complete front-end part and the most of back-end of the website.
Tinda
Drupal , jQuery, Highcharts
An application which allows assessment of digital competencies of professionals.
Added an module to download the responses of users to questionnaires on digital competencies following the DigiComp Framework.
Added a dashboard visualizing users’ responses and their overall score for digital competencies.
Added a report download functionality.
Seeds
Python , Django, jQuery, Bootstrap, Plotly
A map-based application to allows users to filter energy transition scenario based on their preferences.
Handled the entire development of the project including front-end and back-end.
