Individual differences in online and computer-based learning : gifted and other diverse populations
\"In 1894 John Dewey established his experimental laboratory school at the University of Chicago, with a focus on teaching each student according to their individual differences. This concept indicated a shift away from the emphasis on communal, classroom teaching, which marked educational practices in the nineteenth century during the advent of widely available public education. With the introduction of computer-based online instruction in schools, curricula are able to be fully informed by individual difference, subtly and quickly tracking students' progress. In these courses, teachers play the role of troubleshooters instead of lecturers. Individual Differences examines a large number of studies on computer-based and online instruction, with special attention paid to gifted students in the fields of mathematics, science, technology, and engineering. Other chapters also focus on a wide variety of student populations: deaf students, American Indian rural students, and underachieving, impoverished students. \"-- Provided by publisher.

A Cost-Effectiveness Analysis of Blended Versus Face-to-Face Delivery of Evidence-Based Medicine to Medical Students
Blended learning describes a combination of teaching methods, often utilizing digital technologies. Research suggests that learner outcomes can be improved through some blended learning formats. However, the cost-effectiveness of delivering blended learning is unclear.
This study aimed to determine the cost-effectiveness of a face-to-face learning and blended learning approach for evidence-based medicine training within a medical program.
The economic evaluation was conducted as part of a randomized controlled trial (RCT) comparing the evidence-based medicine (EBM) competency of medical students who participated in two different modes of education delivery. In the traditional face-to-face method, students received ten 2-hour classes. In the blended learning approach, students received the same total face-to-face hours but with different activities and additional online and mobile learning. Online activities utilized YouTube and a library guide indexing electronic databases, guides, and books. Mobile learning involved self-directed interactions with patients in their regular clinical placements. The attribution and differentiation of costs between the interventions within the RCT was measured in conjunction with measured outcomes of effectiveness. An incremental cost-effectiveness ratio was calculated comparing the ongoing operation costs of each method with the level of EBM proficiency achieved. Present value analysis was used to calculate the break-even point considering the transition cost and the difference in ongoing operation cost.
The incremental cost-effectiveness ratio indicated that it costs 24% less to educate a student to the same level of EBM competency via the blended learning approach used in the study, when excluding transition costs. The sunk cost of approximately AUD $40,000 to transition to the blended model exceeds any savings from using the approach within the first year of its implementation; however, a break-even point is achieved within its third iteration and relative savings in the subsequent years. The sensitivity analysis indicates that approaches with higher transition costs, or staffing requirements over that of a traditional method, are likely to result in negative value propositions.
Under the study conditions, a blended learning approach was more cost-effective to operate and resulted in improved value for the institution after the third year iteration, when compared to the traditional face-to-face model. The wider applicability of the findings are dependent on the type of blended learning utilized, staffing expertise, and educational context.

Inside Mathforum.org : analysis of an Internet-based education community
The internet has dramatically transformed social space and time for many people in many different contexts. This dramatic warping of the social fabric has happened slowly over time as digital technologies have evolved and internet speeds have increased. While we are all aware of these changes, the impact is often little understood. There are few monographs about social groups made possible by the internet, and even fewer about educational communities made possible through digital technologies. 'Inside Mathforum.org' details the ways that digital media are used to enhance the practices that teachers and students of mathematics engage in. The book also shows how different kinds of mathematical conversations and interactions become possible through the digital media. Unlike many other educational uses of digital media, the Math Forum's community has provided online resources and sustained support for teachers and students, and it leads the way in showing the power of digital media for education.

ChatGPT-generated help produces learning gains equivalent to human tutor-authored help on mathematics skills
Authoring of help content within educational technologies is labor intensive, requiring many iterations of content creation, refining, and proofreading. In this paper, we conduct an efficacy evaluation of ChatGPT-generated help using a 3 x 4 study design (N = 274) to compare the learning gains of ChatGPT to human tutor-authored help across four mathematics problem subject areas. Participants are randomly assigned to one of three hint conditions (control, human tutor, or ChatGPT) paired with one of four randomly assigned subject areas (Elementary Algebra, Intermediate Algebra, College Algebra, or Statistics). We find that only the ChatGPT condition produces statistically significant learning gains compared to a no-help control, with no statistically significant differences in gains or time-on-task observed between learners receiving ChatGPT vs human tutor help. Notably, ChatGPT-generated help failed quality checks on 32% of problems. This was, however, reducible to nearly 0% for algebra problems and 13% for statistics problems after applying self-consistency, a “hallucination” mitigation technique for Large Language Models.

Development and Evaluation of a Computer-Animated Tutor for Vocabulary and Language Learning in Children with Autism
Using our theoretical framework of multimodal processing, we developed and evaluated a computer-animated tutor, Baldi, to teach vocabulary and grammar for children with autism. Baldi was implemented in a Language Wizard/Player, which allows easy creation and presentation of a language lesson involving the association of pictures and spoken words. The lesson plan includes both the identification of pictures and the production of spoken words. In Experiment 1, eight children were given initial assessment tests, tutorials, and reassessment tests 30 days following mastery of the vocabulary items. All of the students learned a significant number of new words and grammar. A second within-subject design with six children followed a multiple baseline design and documented that the program was responsible for the learning and generalization of new words. The research indicates that children with autism are capable of learning new language within an automated program centered around a computer-animated agent, multimedia, and active participation and can transfer and use the language in a natural, untrained environment.

Long-term effects of an e-learning course on patient safety: A controlled longitudinal study with medical students
To improve patient safety, educational interventions on all system levels, including medical school are necessary. Sound theoretical knowledge on elements influencing patient safety (such as error management or team work) is the basis for behavioral changes of health care professionals.
A controlled, quasi-experimental study with repeated measures was deployed. The intervention group participated in a mandatory e-learning course on patient safety (ELPAS) between October 2016 and December 2016. The control group did not receive any didactic session on patient safety. In both groups we measured technical knowledge and attitudes towards patient safety before the intervention (T0), directly after the intervention (T1) and one year after the intervention (T2). Participants were 309 third-year medical students in the intervention group and 154 first- and second-year medical students in the control group.
Technical knowledge in the intervention group (but not the control group) improved significantly after the intervention and remained high after one year (F(2, 84) = 13.506, p < .001, η2 = .243). Students of the intervention group felt better prepared for safe patient practice, even one year after the intervention F(2, 85) = 6.743, p < .002, η2 = .137). There was no sustainable significant effect on attitudes towards patient safety.
This study shows, that eLearning interventions can produce significant long-term effects on patient safety knowledge, however, the study did not show long-term effects on attitudes towards patient safety. Our study implies two potential developments for future research: e-learning might be used in combination with face-to-face sessions, or more intensive (in terms of frequency and duration) e-learning sessions may be needed to achieve lasting changes in attitude.

Multimodal Literacies and Emerging Genres
A student's avatar navigates a virtual world and communicates the desires, emotions, and fears of its creator. Yet, how can her writing instructor interpret this formof meaningmaking?Today, multiple modes of communication and information technology are challenging pedagogies in composition and across the disciplines. Writing instructors grapple with incorporating new forms into their curriculums and relating them to established literary practices. Administrators confront the application of new technologies to the restructuring of courses and the classroom itself.Multimodal Literacies and Emerging Genresexamines the possibilities, challenges, and realities of mutimodal composition as an effective means of communication. The chapters view the ways that writing instructors and their students are exploring the spaces where communication occurs, while also asking \"what else is possible.\" The genres of film, audio, photography, graphics, speeches, storyboards, PowerPoint presentations, virtual environments, written works, and others are investigated to discern both their capabilities and limitations. The contributors highlight the responsibility of instructors to guide students in the consideration of their audience and ethical responsibility, while also maintaining the ability to \"speak well.\" Additionally, they focus on the need for programmatic changes and a shift in institutional philosophy to close a possible \"digital divide\" and remain relevant in digital and global economies.Embracing and advancing multimodal communication is essential to both higher education and students. The contributors therefore call for the examination of how writing programs, faculty, and administrators are responding to change, and how the many purposes writing serves can effectively converge within composition curricula.
