Web-based versus face-to-face learning of diabetes management: the results of a comparative trial of educational methods.

BACKGROUND AND OBJECTIVES: Relatively little is known about the effectiveness of Web-based learning (WBL) in medical education and how it compares to conventional methods. This study examined the influence of an interactive, online curriculum in a third-year medical school family medicine clerkship on students' ability to create a management plan for a patient newly diagnosed with type 2 diabetes. We also evaluated how the online curriculum compared to a conventionally taught curriculum. METHODS: The online course included three integrated activities: (1) self-study modules, (2) a patient case study, and (3) a moderated discussion board for posting and discussing patient care plans. The WBL curriculum was compared to small-group case-based sessions with a faculty facilitator. Students completed a test case before and after the clerkship. RESULTS: Among standard-of-care diabetic management interventions not ordered on the pretest, 38% were subsequently correctly ordered by WBL students on the posttest, versus 33% by students in the comparison group. For four out of five subgroups assessed on the case write-ups, the gain from before to after the clerkship favored the WBL group. CONCLUSIONS: Improvement among students learning online exceeded that of students learning face to face. This suggests superiority of the online method, a finding consistent with other recently published, well-controlled studies.

HEAL: an instructional design model applied to an online clerkship in family medicine.

OBJECTIVE: The potential of distance learning technology to deliver educational programs in which instruction and evaluation are of a consistent and high standard across multiple settings is hampered by a lack of instructional design models. In response, we developed the HEAL (Heuristic for Electronic Asynchronous Learning) model for designing online curricula. DESCRIPTION: HEAL is based on the theories that learning is facilitated by independent problem solving, investigation, and discovery (heuristics); collaboration between students fosters learning; and the proven educational cycle of practice, feedback, and reflection is integral to the interrelated domains of skill development and personal awareness.(1) The HEAL model is defined by synergistic online learning activities integrated with real patient care. It is applicable to all medical education levels. We applied this innovative design template to an online curriculum that augments our conventional six-week third-year clerkship. Our students, who were placed in distant family physician offices, needed more interaction and learning from peers and faculty. The three elements of HEAL, and implementation in the "online clerkship," are: (1) Didactic modules teach and illustrate concepts. Students study modules (HTML pages) on management of diabetes (DM), and complete five modules on evidence-based medicine (EBM). They do EBM literature searches reviewed online by peers, faculty, and librarians, who provide feedback. (2) A problem-based case discussion promotes application of concepts from modules (horizontal curricular integration). Students view streamed video of a patient with a history suggestive of diabetes, review her medical chart online, and suggest evidence-based management in an asynchronous discussion group. The case progresses weekly to mimic 12 months of continuity of care. (3) A collaborative journal activity explores the results of applying elements one and two to real patients (vertical integration). Additional elements advance reflection, professionalism, and medical humanism. Participation in the journal discussion group, stimulated by online readings, enhances self-awareness, informs psychosocial aspects of element 2, and promotes generalization of learning objectives to real patients. We use BlackBoard software. Students log in two to three times per week. Faculty who are trained in online moderation facilitate the threaded discussion groups and provide feedback. DISCUSSION: Students in alternating clerkship blocks complete the online clerkship. Their performance is compared with that of students who complete a face-to-face diabetes curriculum, but no curriculum on EBM or medical humanism. After nearly a year (105 students), compared with the non-online group, students completing the online clerkship demonstrated greater gains in reported EBM skills from preto post-clerkship, larger increases in mean score (from pre to post) on a medical-humanism aptitude scale, and higher scores on a post-clerkship diabetes management assessment (all comparisons p <.05). The online clerkship will become a permanent part of our clerkship and we have begun to use HEAL to design other online courses, including continuing education courses.

Ethics in medicine: are we blind? In support of teaching medical ethics at the bedside.

The ability to recognize and respond to the ethical dimension of medicine is integral to providing health care that is comprehensive and humane. However, this aspect of medical practice is underemphasized in clinical and academic medicine, despite attempts to devise curricula in this field. This paper examines the origins and consequences of this deficiency through a case history of a Jehovah's Witness who reluctantly accepted a blood transfusion. It emphasizes the ubiquity of the ethical context in medicine and argues that blindness to this context stems from the prevailing scientific and technological paradigm in medicine. Innovations in medical education are called for to enhance health care providers' abilities to appreciate and cope with these complex situations.

Collaborative e-learning using streaming video and asynchronous discussion boards to teach the cognitive foundation of medical interviewing: a case study.

BACKGROUND: Advances in electronic technology have created opportunities for new instructional designs of medical curricula. OBJECTIVE: We created and evaluated a 4-week online elective course for medical students to teach the cognitive basis for interviewing skills. METHODS: Ten students, from 2 medical schools, studied online modules on interviewing concepts and viewed videos illustrating the concepts. They then participated in asynchronous discussion groups designed to reinforce course concepts, stimulate reflective learning, and promote peer learning. RESULTS: In qualitative evaluations, learners reported improvements in self-awareness; increased understanding of interviewing concepts; and benefits of online learning vs face to face learning. Participants reported high levels of satisfaction with online learning and with achievement of course objectives. Self-reported knowledge scores increased significantly from pre-course completion to post-course completion. CONCLUSIONS: Online education has significant potential to augment curriculum on the medical interview, particularly among students trained in community settings geographically distant from their academic medical center.
