CoTrack
CoTrack is a web-based tool to conduct collaborative activity in online
space as well as physical space. It uses
Etherpad to offer a
collaborative writing space. In addition to offering collaboration space,
CoTrack also allows capturing of participants' activities, happening in
digital and physical spaces (e.g., speaking time, turn-taking, number of
characters written/deleted, etc.).
The primary stakeholders of CoTrack are Teachers and Computer-supported
collaborative learning(CSCL) Researchers. Teachers can use CoTrack to
conduct group activities with monitoring facility, which enable teachers
to identify groups who are in need of help or not participating well.
CSCL Researchers can also use CoTrack to collect data for their study to
understand aspects of collaborative learning (e.g., regulation,
collaboration process). The use of CoTrack benefits researchers by saving
their time otherwise invested in developing/setting up data collection
tools. CoTrack offers researchers pre-processed data from the
group-activity in CSV (Comma Seperated Value) file for further analysis.
CoTrack benefits
- Custom activity design
CoTrack allows teachers/researchers to cusomize the group activity and
data recording. For example, CoTrack supports three different types of
group activities: first, which only involves use of collaborative text
editor; second, which only involves use of audio/video communication
channels; third, which invovles both.
The recording can also be customized, e.g., record only audio or video.
- Multimodal data collection
CoTrack captures following types of data
-
Voice activity detection (VAD): Data indicating whether someone
speaks or not.
-
Speech to text: Transcript from audio data using Google
speech-to-text api in real time (only supported in chrome browser).
-
Writing logs: Log data of participants' writing in
collaborative text editor.
- Activity monitoring
CoTracks offers a real-time dashboard (updates every 30 seconds)
presenting a social network (who is talking after whom network) and
groups' writing activities in terms of number of revisions made.
- Downloading data
CoTrack also facilitates downloading of captured data e.g., VAD,
Speech-to-text, writing logs, in CSV format for later analysis.
- Collaboration quality estimation
CoTrack also offers automated estimation of collaboration quality and potential intervention strategy from learning sciences literature.
