Textbooks have been the traditional method of providing learning content to students for decades, and therefore have become the standard in highquality content. Yet the static textbook format is unable to take advantage of the cognitive and learning science research on effective interactive learning methods. This gap between quality content and highly efficient methods of learning can be closed with advances in artificial intelligence. This paper will contextualize the need for improving textbooks as a learning resource using research-based cognitive and learning science methods, and describe a process by which artificial intelligence transforms textbooks into more effective online learning environments. The goal of this paper is to evaluate textbook-based automatic question generation using student data from a variety of natural learning environments. We believe this analysis, based on 786,242 total observations of student-question interactions, is the largest evaluation of automat...

While research in the learning sciences has spurred advancements in educational technology, the implementation of those learning resources in natural learning contexts advances teaching and learning. In this paper, two faculty members at the University of Central Florida used courseware generated with artificial intelligence as the primary learning resource for their students. The selection and enhancement of this courseware is contextualized for each course. Instructor implementation practices over multiple semesters are described and related to resulting student engagement and exam scores. Finally, benefits of the adaptive courseware are discussed not only for student outcomes, but the qualitative changes faculty identified and the impact that iterative changes in teaching practice had on instructors as well as students.

Although content creators, instructors, and students alike see the value in providing interactive courseware to help students learn, they remain a costly solution to create. Platforms that allow the creation and delivery of interactive courseware are only fully utilized by those who can afford the labor cost of building hundreds of formative items just to start. Most of the time this means barriers are too high in either financial cost or extremely long development timelines. Our solution is called SmartStart, a process that works to reduce these barriers to creating courseware by automating basic steps that otherwise require significant manual labor. Automatic question generation (AQG) is one in a series of steps in the SmartStart process that work together to transform textbook content into a courseware learning environment.

Courseware is a comprehensive learning environment that engages students in a learning by doing approach while also giving instructors data-driven insights on their class, providing a scalable solution for many instructional models. However, courseware-and the volume of formative questions required to make it effective-is time-consuming and expensive to create. By using artificial intelligence for automatic question generation, we can reduce the time and cost of developing formative questions in courseware. However, it is critical that automatically generated (AG) questions have a level of quality on par with human-authored (HA) questions in order to be confident in their usage at scale. Therefore, our research question is: are student interactions with AG questions equivalent to HA questions with respect to engagement, difficulty, and persistence metrics? This paper evaluates data for AG and HA questions that students used as formative practice in their university Communication course. Analysis of AG and HA questions shows that our first generation of AG questions perform equally well as HA questions in multiple important respects.

Introduction This study evaluated the usability and effectiveness of an artificial intelligence Braille Tutor designed to supplement the instruction of students with visual impairments as they learned to write braille contractions. Methods A mixed-methods design was used, which incorporated a single-subject, adapted alternating treatments design as well as qualitative teacher interviews and surveys. Results Students seemed to reach 100% accuracy faster when using Braille Tutor (average = 7.0 sessions; range 1.0 to 12.0 sessions) than when they did not (average 9.6 sessions with a teacher of students with visual impairments; range 3.0 to 16.0 sessions). Also, students who used Braille Tutor more often tended to learn more contractions overall during the study (average = 21.25; range 13.0 to 30.0) than students who used it less (average 9.0; range 9.0 to 9.0). Discussion The first trend noted was that students in the teacher of students with visual impairments plus Braille Tutor phase...

The purpose of this paper is to explain the learning methodologies behind the adaptive activities within Acrobatiq’s courseware, and to investigate the impact of these adaptive activities on learning estimates and summative assessment scores using real course data. The adaptive activities used for this analysis were part of a Probability and Statistics course, which was delivered to college students at a public four-year institution as part of an educational grant. The data were analyzed to identify if the adaptive activities had an impact on learning estimates as well as on summative assessment scores. Results showed that the adaptive activities had a net positive effect on learning estimates. Results also showed that not only did learning estimate states correlate to mean summative assessment scores, but improving learning estimates after completing the adaptive activity practice yielded higher mean summative assessment scores. The implications of this analysis and future research are discussed.

ABSTRACT: Prior research demonstrates that students learn more from homework practice when using online homework or intelligent tutoring systems than a paper-and-pencil format. However, no accounting education research directly compares the learning effects of online homework systems with the learning effects of intelligent tutoring systems. This paper presents a quasi-experiment that compares the two systems and finds that students’ transaction analysis performance increased at a significantly faster rate when they used an intelligent tutoring system rather than an online homework system. Implications for accounting instructors and researchers are discussed.

In introductory accounting textbooks, virtually all end-of-chapter problems on transaction analysis follow the same familiar format: a collection of transactions performed by a given business during a specified time period. Modern research-based models of human cognitive architecture suggest, however, that this format is suboptimal for beginning students. An approach better aligned with this learning research would give students practice with one transaction type at a time before proceeding to problems involving a mixture of transaction types. An experiment was conducted to test this hypothesis by randomly assigning students in an introductory financial accounting course to one of two practice conditions: conventional textbook problems and “targeted practice” in which the same transactions were grouped by type. All students were then given a conventional textbook problem as a post-test. During the practice phase, students in the targeted practice group analyzed transactions in less ...
