Online discussion forums are highly valued by instructors due to their affordance for understanding class activities and learning. However, a discussion forum with a great number of posts requires a large amount of time to view, and help requests are easily overlooked. Various machine-learning--based tools have been developed to help instructors…

In online courses, discussion forums play a key role in enhancing student interaction with peers and instructors. Due to large enrolment sizes, instructors often struggle to respond to students in a timely manner. To address this problem, both traditional machine learning (ML) (e.g., Random Forest) and deep learning (DL) approaches have been…

The purpose of this Action Research study was to examine, understand, strengthen, and improve how virtual platforms can be used to support the challenges novice teachers face. This document will outline the study's objective for collecting data within the initial stages of this action research study. By fostering deeper relationships between…

This article provides computational and rule-based approaches for detecting confusion that is expressed in students' comments in couse forums. To obtain reliable, ground truth data about which posts exhibit student confusion, we designed a decision tree that facilitates the manual labeling of forum posts by experts. However, manual labeling is…

When problem based learning occurs in a social context it is open to a common social behaviour, scrounging. In the animal behaviour literature, scroungers do not attempt to find resources themselves but rather exploit resources found by other group members (referred to as producers). We know from studies of animal behaviour (including humans) that…

Information used to assist biomedical and clinical research has largely comprised of data available in published sources like scientific papers and journals, or in clinical sources like patient health records, lab reports and discharge summaries. Information from such sources, though extensive and organized, is often not readily available due to…

Discussion forums in learning management systems (LMS) have been shown to promote student interaction and contribute to the collaborative practice in the teaching-learning process. By evaluating the postings, teachers can identify students with learning difficulties. However, due to the large volume of posts that are generated on a daily basis in…

We aimed at investigating knowledge revealed by the tutors of a continuing education course for mathematics teachers offered at a distance. Initially, we observed the work of 32 tutors over a year, in order to typify their interventions in discussion forums with course participants. From the results, we offered training to a new group of tutors,…

Online education and in particular Massive Open Online Courses (MOOCs) are often regarded as a way to solve global educational challenges. In this article, we highlight the students' uptake of such a 'digital solution'. Presenting initial findings from a research project in Germany, we situate our investigation in the specific context of digital…

This study explores the combination of course structure, prompt type, and characteristics of discussion posts and their relationships with intersubjectivity. A content analysis measured the intersubjectivity of peer responses by analyzing the interaction analysis model (IAM) phase of each post and comparing with the IAM phase of the previous post.…

This case study examined an authentic online learning phenomenon where social conflict, including harsh critique and negative tone, weaved throughout peer-moderated online discussions in an online class. Opening coding and content analysis were performed on 1306 message units and course artifacts. The results revealed that a model of social…

Neo magnets are neodymium magnet beads that have been marketed as a desktop toy. We proposed using neo magnets as an alternative building block to traditional ball-and-stick models to construct carbon allotropes, such as fullerene and various nanocone structures. Due to the lack of predetermined physical connections, the versatility of carbon…

E-learning is an important trend globally that is believed to enhance the acquisition of knowledge by students within and outside the classroom to improve their academic pursuit. The Online Discussion Forum (ODF) is one of the tools that are used for e-learning in Nigerian universities. It facilitates interaction among postgraduate students as…

Determining how learners use MOOCs effectively is critical to providing feedback to instructors, schools, and policy-makers on this highly scalable technology. However, drawing inferences about student learning outcomes in MOOCs has proven to be quite difficult due to large amounts of missing data (of various kinds) and to the diverse population…

In this paper, we describe a novel methodology, grounded in techniques from the field of machine learning, for modeling emerging social structure as it develops in threaded discussion forums, with an eye towards application in the threaded discussions of massive open online courses (MOOCs). This modeling approach integrates two simpler, well…
