Our study asked if technology mediated learning environments using AR （augmented reality） can enhance student learning in the architecture and engineering disciplines. There were multiple study sites, two of them University of Arkansas and Florida International University are discussed. At each site, three collaborative projects were assigned to student teams during fall 2016. Students analyzed an existing building and developed alternative solutions based on improving energy performance. Our paper presents： （1） the research challenge related to the integration of immersive head-mounted display technology providing visual simulations and interactive lessons for interdisciplinary collaboration; and （2） the progress of Phase 1 consisting of our control group results run without the use of AR technology.展开更多

The custom haptic syringe interface provides a more realistic tactile sensation of plunging a real syringe in a human patient. This pilot study investigated the usability of the custom haptic syringe to replace one of the hand controllers to provide a more realistic and better training experience. Method: A one group pre-post survey investigated student perceptions regarding the effectiveness and usability of a haptic syringe to provide a more realistic experience to train dental students to learn the procedural steps to inject local anesthesia into a virtual patient. Twenty-two third year dental students participated. The pre-post survey examined changes in students’ perceived emotions, preparedness, and effectiveness of the VRLA as a foundational learning strategy prior to entering clinical group practice. Results: While quantitative results on comparable survey questions did not yield statistically significant differences, qualitative open-ended responses revealed a much greater satisfaction using the custom haptic syringe compared to the out of the box controllers. Conclusions: Feedback regarding the haptic syringe showed a substantial step closer to providing a more real experience for students in an effort to create a better bridge between classroom learning and clinical practice in order to prepare students to more confidently and competently work with real clients. Further refinement of the syringe is forthcoming along with a more formal comparative experimental study.展开更多

The progress of student physicians tends to be measured by their ability to synthesize and demonstrate basic medical knowledge and clinical skills but offers little assessment of the maturation of attitudes or their values. The University of New England College of Osteopathic Medicine (UNECOM), immerses second year medical students in a hospice home for 48 hours to enhance students’ perspectives in interprofessional palliative and end of life care. Methods: This project utilized qualitative ethnographic and autobiographic research designs. Two female second year medical students (27 y/o & 26 y/o) were immersed for 48 hours into a local hospice home, sleeping in a bed where others had died, to answer the question: “What is it like for ME to live in the Hospice Home for 48 hours and how does this contribute to my future as a practitioner?” Data were collected in the form of journal notes for pre-fieldwork, fieldwork, and post-fieldwork and included subjective and objective reporting of observations, experiences, and patient/family encounters. Analyses included journal review and thematic categorization and coding through content analysis. Results: Themes common to both students that factored in the research question and their prior stated interest areas of medical humanities and person-centered care at end of life were identified. Three themes were selected for this article: 1) Person-Centered Experiences, 2) Spectrum of Communication, and 3) Introspection: Attitudes and Values. The process of living in the hospice home for 48 hours revealed students’ attitudes about various disease processes, their personal experiences with death and dying, and their assumptions about how patients approach death. Conclusion: This Hospice Home Immersion project provided both an educational approach and learning environment that was effective in advancing medical students’ attitudes, skills, and knowledge as evidenced by their self-reported life altering learning about end of life and palliative care.展开更多
