Motivating and retaining online students : research-based strategies that work
Finally, the first research-based book of sound strategies and best practices to help instructors motivate students to complete their online courses. Although studies support the effectiveness of learning online, students often fail to complete online courses. Some studies have found that as many as 50-70% drop out of their online courses or programs. Retention is not only a growing expectation and imperative, but it is also as opportunity for faculty members to take the lead in innovating, researching, and implementing new strategies while demonstrating their effectiveness. Designed for instructors and instructional designers, \"Motivating and Retaining Online Students\" is filled with empirical research from the authors' study of motivation and retention strategies that can reduce online learner dropout. Focusing on the most important issues instructors face, such as course design; student engagement and motivation; and institutional, instructional, and informal student support strategies, the book provides effective online strategies that help minimize student dropout, increase student retention, and support student learning. While helping to improve the overall retention rates for educational institutions, the strategies outlined in the book also allow for student diversity and individual learner differences. Lehman and Conceicao's proven model gives instructors an effective approach to help students persist in online courses and succeed as learners. -- Provided by publisher
ChatGPT-generated help produces learning gains equivalent to human tutor-authored help on mathematics skills
2024
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.

A Cost-Effectiveness Analysis of Blended Versus Face-to-Face Delivery of Evidence-Based Medicine to Medical Students
2015
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.

Teaching history in the digital age
\" Although many humanities scholars have been talking and writing about the transition to the digital age for more than a decade, only in the last few years have we seen a convergence of the factors that make this transition possible: the spread of sufficient infrastructure on campuses, the creation of truly massive databases of humanities content, and a generation of students that has never known a world without easy Internet access. Teaching History in the Digital Age serves as a guide for practitioners on how to fruitfully employ the transformative changes of digital media in the research, writing, and teaching of history. T. Mills Kelly synthesizes more than two decades of research in digital history, offering practical advice on how to make best use of the results of this synthesis in the classroom and new ways of thinking about pedagogy in the digital humanities\"-- Provided by publisher.

Executive functions (EFs) training interventions aimed at ADHD-symptom reduction have yielded mixed results. Generally, these interventions focus on training a single cognitive domain (e.g., working memory [WM], inhibition, or cognitive-flexibility). However, evidence suggests that most children with ADHD show deficits on multiple EFs, and that these EFs are largely related to different brain regions. Therefore, training multiple EFs might be a potentially more effective strategy to reduce EF-related ADHD symptoms.
Eighty-nine children with a clinical diagnosis of ADHD (aged 8-12) were randomized to either a full-active-condition where visuospatial WM, inhibition and cognitive-flexibility were trained, a partially-active-condition where inhibition and cognitive-flexibility were trained and the WM-training task was presented in placebo-mode, or to a full placebo-condition. Short-term and long-term (3-months) effects of this gamified, 25-session, home-based computer-training were evaluated on multiple outcome domains.
During training compliance was high (only 3% failed to meet compliance criteria). After training, only children in the full-active condition showed improvement on measures of visuospatial short-term-memory (STM) and WM. Inhibitory performance and interference control only improved in the full-active- and the partially-active condition. No Treatment-condition x Time interactions were found for cognitive-flexibility, verbal WM, complex-reasoning, nor for any parent-, teacher-, or child-rated ADHD behaviors, EF-behaviors, motivational behaviors, or general problem behaviors. Nonetheless, almost all measures showed main Time-effects, including the teacher-ratings.
Improvements on inhibition and visuospatial STM and WM were specifically related to the type of treatment received. However, transfer to untrained EFs and behaviors was mostly nonspecific (i.e., only interference control improved exclusively in the two EF training conditions). As such, in this multiple EF-training, mainly nonspecific treatment factors - as opposed to the specific effects of training EFs-seem related to far transfer effects found on EF and behavior.

Education and technology : key issues and debates
\"Will technology replace the school and university? Will technology replace the teacher? What do we really know about technology and learning? Does technology make education more individualized? What does the future hold for technology and education? What can be learnt from the history of technology use in education? In a thoroughly revised edition of this successful book, Neil Selwyn takes a critical look at some of the major current debates and controversies concerning digital technologies and education. Focusing on the social as well as the technical aspects of these issues, Selwyn addresses fundamental but often unvoiced questions about education and technology. Over the course of eight chapters, the book gives careful thought to the people, practices, processes and structures behind the rapidly increasing use of technologies in education, with an emphasis on the implications of digital technologies for individuals and institutions. The book focuses attention on the connections between recent technology developments and broader changes in education practice, education policy and education theory over the past 10 years. It also challenges us to reflect on future directions and controversies for education in the (post)digital age. Expanded study questions, annotated further reading and a new glossary of key terms are included to support readers. An updated companion website links to case study examples, two bonus chapters and much more for students and lecturers.\"-- Provided by publisher.
Asynchronous Distance Learning of the National Institutes of Health Stroke Scale During the COVID-19 Pandemic (E-Learning vs Video): Randomized Controlled Trial
2021
The COVID-19 pandemic has considerably altered the regular medical education curriculum while increasing the need for health care professionals. Senior medical students are being incrementally deployed to the front line to address the shortage of certified physicians. These students, some of whom will be fast-tracked as physicians, may lack knowledge regarding the initial management of time-critical emergencies such as stroke.
Our aim was to determine whether an e-learning module could improve asynchronous distance knowledge acquisition of the National Institutes of Health Stroke Scale (NIHSS) in senior medical students compared to the traditional didactic video.
A randomized, data analyst-blinded web-based trial was conducted at the University of Geneva Faculty of Medicine between April and June 2020. Fifth year medical students followed a distance learning path designed to teach the NIHSS. The control group followed the traditional didactic video created by Patrick Lyden, while the e-learning group followed the updated version of a previously tested, highly interactive e-learning module. The main outcome was the score on a 50-question quiz displayed upon completion of the learning material. The difference in the proportion of correct answers for each specific NIHSS item was also assessed.
Out of 158 potential participants, 88 started their allocated learning path and 75 completed the trial. Participants who followed the e-learning module performed better than those who followed the video (38 correct answers, 95% CI 37-39, vs 35 correct answers, 95% CI 34-36, P<.001). Participants in the e-learning group scored better on five elements than the video group: key NIHSS concepts (P=.02), the consciousness - global item (P<.001), the facial palsy item (P=.04), the ataxia item (P=.03), and the sensory item (P=.04).
Compared to the traditional didactic video, a highly interactive e-learning module enhances asynchronous distance learning and NIHSS knowledge acquisition in senior medical students.

Background
Cost-effective methods to facilitate practical medical education are in high demand and the “mixed-reality” (MR) technology seems suitable to provide students with instructions when learning a new practical task. To evaluate a step-by-step mixed reality (MR) guidance system for instructing a practical medical procedure, we conducted a randomized, single-blinded prospective trial on medical students learning bladder catheter placement.
Methods
We enrolled 164 medical students. Students were randomized into 2 groups and received instructions on how to perform bladder catheter placement on a male catheterization training model. One group (107 students) were given their instructions by an instructor, while the other group (57 students) were instructed via an MR guidance system using a Microsoft HoloLens. Both groups did hands on training. A standardized questionnaire covering previous knowledge, interest in modern technologies and a self-evaluation was filled out. In addition, students were asked to evaluate the system’s usability. We assessed both groups’s learning outcome via a standardized OSCE (objective structured clinical examination).
Results
Our evaluation of the learning outcome revealed an average point value of 19.96 ± 2,42 for the control group and 21.49 ± 2.27 for the MR group - the MR group’s result was significantly better (
p
= 0.00). The self-evaluations revealed no difference between groups, however, the control group gave higher ratings when evaluating the quality of instructions. The MR system’s assessment showed less usability, with a cumulative SUS (system usability scale) score of 56.6 (lower half) as well as a cumulative score of 24.2 ± 7.3 (
n
= 52) out of 100 in the NASA task load index.
Conclusions
MR is a promising tool for instructing practical skills, and has the potential to enable superior learning outcomes. Advances in MR technology are necessary to improve the usability of current systems.

UnderstAID, an ICT Platform to Help Informal Caregivers of People with Dementia: A Pilot Randomized Controlled Study
2016
Information and communications technology (ICT) could support ambient assisted living (AAL) based interventions to provide support to informal caregivers of people with dementia, especially when they need to cope with their feelings of overburden or isolation. An e-learning platform (understAID application) was tested by informal caregivers from Denmark, Poland, and Spain to explore the technical and the pedagogical specifications, as well as evaluating the impact of its use on the psychological status of the participants. 61 informal caregivers completed the study taking part in the experimental (n=30) or control (n=31) groups. 33.3% of the caregivers were satisfied with the application and around 50% of the participants assessed it as technically and pedagogically acceptable. After using understAID the caregivers in the experimental group significantly decreased their depressive symptomatology according to the Center for Epidemiologic Studies Depression scale, but a possible benefit on their feelings of competence and satisfaction with the caring experience was also observed. The low scores obtained for satisfaction were highlighting issues that need to be modified to meet the informal caregivers’ needs in national, social, and cultural context. Some possible biases are also considered and discussed to be taken into account in future improvements of understAID application.
