Deepfakes are synthetic content generated using advanced deep learning and AI technologies. The advancement of technology has created opportunities for anyone to create and share deepfakes much easier. This may lead to societal concerns based on how communities engage with it. However, there is limited research available to understand how communiti...

Deepfakes created in the form of image, audio and video by leveraging AI are far more realistic to identify if its being synthetically created by replacing someone else's voice or video. This is an emerging concern as the implications of such technology may distress the society. Currently, much of the scholarly research is centered on the technolog...

The appearance of Deepfake tools and technologies in the public is proliferating. Scholarly research is very centered on technology of deepfake but sparse in understanding how the emergence of deepfakes impacts society. In this systematic review, we explored deep-fake scholarly works that discuss societal implications than the technology-centered f...

MOOC participants often feel isolated and disconnected from their peers. Navigating meaningful peer interactions, generating a sense of belonging, and achieving social presence are all major challenges for MOOC platforms. MOOC users often rely on external social platforms for such connection and peer interaction, however, off-platform networking of...

Massive Open Online Courses (MOOCs) often lack valuable social presences that provide learners opportunities to interact and to be feel as a real person. This subjective experience of being present with a “real” person and having access to their thoughts and emotions increase the learning experience.

We report on a systematic review of the landscape of peer assessment in massive open online courses (MOOCs) with papers from 2014 to 2020 in 20 leading education technology publication venues across four databases containing education technology-related papers, addressing three research issues: the evolution of peer assessment in MOOCs during the p...

MOOC user behavior is generally studied using the data collected within platform interactions in the learning system or via outside social media platforms. It is important to understand the root causes of anomalies in MOOCs, such as the 80% attrition, less interactions within platforms and what causing the reflected behaviors beyond platforms. We s...

Massive open online courses (MOOCs) have considered to be a potential to disseminate engineering education at scale. However, the pedagogical requirement demanded engineering student to equip with specific skillsets such as communication, interactivity and collaboration. Yet, MOOCs are skeptical of facilitating those skills. Generally, MOOCs evalua...

Paid crowdsourcing platforms suffer from low-quality work and unfair rejections, but paradoxically, most workers and requesters have high reputation scores. These inflated scores, which make high-quality work and workers difficult to find, stem from social pressure to avoid giving negative feedback. We introduce Boomerang, a reputation system for c...

Massive Open Online Courses (MOOCs) often use peer grading which enables the use of open ended questions in assignments at scale. Open ended questions enhance students' creativity and improve cognition. However, this peer grading includes drawback such as missing or low quality feedback, and inconsistency between peer graders. In design studios and...

Massive Open Online Courses (MOOCs) are education technologies which capable of teaching thousands of students synchronously. The pedagogy in MOOCs are focus on decentralized learners where students watch videos, take quizzes, submit assignments and discuss using forums. This pedagogy is focusing on the didactic method of teaching. However, the stu...

Low-quality results have been a long-standing problem on microtask crowdsourcing platforms, driving away requesters and justifying low wages for workers. To date, workers have been blamed for low-quality results: they are said to make as little effort as possible, do not pay attention to detail, and lack expertise. In this paper, we hypothesize tha...

Massive Open Online Courses (MOOCs) use peer assessment to grade open ended questions at scale, allowing students to provide feedback. Relative to teacher based grading, peer assessment on MOOCs traditionally delivers lower quality feedback and fewer learner interactions. We present the identified peer review (IPR) framework, which provides non-bli...
