Logic as a knowledge representation and reasoning language is a fundamental topic of an Artificial Intelligence (AI) course and includes a number of sub-topics. One of them, which brings difficulties to students to deal with, is converting natural language (NL) sentences into first-order logic (FOL) formulas. To assist students to overcome those…

This study gathered data about communication centers and built on past investigations of how centers function across the United States. Communication center directors or individuals who oversee centers at two- and four-year institutions of higher education (N = 47) were surveyed. Participants responded to questions about center structure and…

Drop-in peer tutoring is the most popular model on college campuses, but a high student-tutor ratio suggests that students will spend the majority of their lab time working without the aid of a tutor. This study observed students in a drop-in tutoring center serving developmental math students and explored what they do in that independent time.…

This study investigated the impact of pedagogical agents' conversational formality on learning and engagement in a trialog-based intelligent tutoring system (ITS). Participants (N = 167) were randomly assigned into one of three conditions to learn summarization strategies with the conversational agents: (1) a "formal" condition in which…

We propose a data driven method for decomposing population level learning curve models into mutually exclusive distinctive groups each consisting of similar learning trajectories. We validate this method on six knowledge components from the log data from an online tutoring system ASSISTment. Preliminary analysis reveals interpretable patterns of…

The 1993 paper in "IJAIED" on evaluation methods for Intelligent Tutoring Systems (ITS) still holds up well today. Basic evaluation techniques described in that paper remain in use. Approaches such as kappa scores, simulated learners and learning curves are refinements on past evaluation techniques. New approaches have also arisen, in…

We reflect upon a paper we wrote that was published in 1995 (20 years ago). We outline the motivation for the work and situate it in the state of the art at that time. We suggest that a key contribution was to highlight the need to provide support for learners who reason with external representations. The support must be flexible enough to…

"An Architecture for Plug-in Tutor Agents" (Ritter and Koedinger 1996) proposed a software architecture designed around the idea that tutors could be built as plug-ins for existing software applications. Looking back on the paper now, we can see that certain assumptions about the future of software architecture did not come to be, making…

This article reports on an investigation into the correlations between students' understandings of introductory astronomy concepts and the correctness and coherency of their written responses to targeted Lecture-Tutorial questions.

Skill prerequisite information is useful for tutoring systems that assess student knowledge or that provide remediation. These systems often encode prerequisites as graphs designed by subject matter experts in a costly and time-consuming process. In this paper, we introduce "Combined student Modeling and prerequisite Discovery"…

Does the communication center, where students tutor peers in oral, written, and digital communication competencies, offer a safe haven for the tutors to "be themselves" among non-judgmental cohorts? Student communication consultants (n = 34) answered Identity Gap Scale questionnaires, supplemented by focus group discussions for randomly…

Canadian multilingualism and multiculturalism are on the rise. Yet, monolingual language instruction remains the standard: students are often discouraged from using their additional languages and teaching materials still lack a plurilingual lens. To further inform the practice of plurilingual pedagogies, this paper reports on results of a…

This paper systematically identifies, maps and evaluates specific types of provision for autistic students published on university websites at 120 institutions throughout the UK. Within these data we identify trends in relation to geographical region, university group, and the Teaching Excellence Framework rating. We employ Nancy Fraser's theory…

As the number of available cybersecurity jobs continues to grow, colleges strive to offer to their cybersecurity students an environment which will make them sufficiently prepared to enter the workforce after graduation. This paper explores the academic and professional needs of STEM-students in various higher education institutions across…

The use of technology as a facilitator in learning environments has become increasingly prevalent with the global pandemic caused by COVID-19. As such, computer-supported collaborative learning (CSCL) gains a wider adoption in contrast to traditional learning methods. At the same time, the need for automated tools capable of assessing and…
