Using assistive technology adaptations to include students with learning disabilities in cooperative learning activities.

Cooperative learning (CL) is a common instructional arrangement that is used by classroom teachers to foster academic achievement and social acceptance of students with and without learning disabilities. Cooperative learning is appealing to classroom teachers because it can provide an opportunity for more instruction and feedback by peers than can be provided by teachers to individual students who require extra assistance. Recent studies suggest that students with LD may need adaptations during cooperative learning activities. The use of assistive technology adaptations may be necessary to help some students with LD compensate for their specific learning difficulties so that they can engage more readily in cooperative learning activities. A process for integrating technology adaptations into cooperative learning activities is discussed in terms of three components: selecting adaptations, monitoring the use of the adaptations during cooperative learning activities, and evaluating the adaptations' effectiveness. The article concludes with comments regarding barriers to and support systems for technology integration, technology and effective instructional practices, and the need to consider technology adaptations for students who have learning disabilities.

New technology in pediatric dentistry.

The goals of creating a generation free of cavities and anxiety are attainable with the acceptance of fluoride, sealants and early dental education. New technology, such as air abrasion, makes possible painless, conservative caries removal when decay is diagnosed early. Digital radiography provides for low-dose X-ray evaluation and diagnosis, and computers give dentists the means for better communication with parents and patients.

[Using the internet in continuous medical education].

BACKGROUND: Modern information technology enables alternative strategies for education and communication. This is a description of a project for systematic utilisation of the internet for distant meetings and professional communication within geriatric medicine. METHOD: A net site has been developed and is being used for the distribution of professionally relevant material, as well as visual aids for audio conferences. The hospitals take their turn giving introductions, and active audience participation is a must. The project has been assessed through a questionnaire survey. RESULTS: 88 audio conferences have been carried out since September 1998. The number of participating hospitals has increased from 6 to 28; the audience varies from 40 to 90 per session. On average, 56% are doctors, 19% nurses, 20% physiotherapists or occupational therapists, 4% have other backgrounds. 100 persons returned the questionnaire (response rate 86%). At an ordinal scale from 1 (bad) to 5 (good), respondents' median global assessment of the project was 4 (interquartile range 3-4); they were particularly satisfied with the professional standard of the lectures, and they found it motivating to work in a field in which modern information technology is put to use. Their use of the net site for other purposes than the audio conferences was very limited. INTERPRETATION: Health professionals in the field of geriatrics saw the project as a help in keeping themselves up to date. Audio conferences may supplement intramural educational sessions but cannot substitute for them.

Evaluating minimally invasive surgery training using low-cost mechanical simulations.

BACKGROUND: The goal of this study was to develop, test, and validate the efficacy of inexpensive mechanical minimally invasive surgery (MIS) model simulations for training faculty, residents, and medical students. We sought to demonstrate that trained and experienced MIS surgeon raters could reliably rate the MIS skills acquired during these simulations. METHODS: We developed three renewable models that represent difficult or challenging segments of laparoscopic procedures; laparoscopic appendectomy (LA), laparoscopic cholecystectomy (LC), and laparoscopic inguinal hernia (LH). We videotaped 10 students, 12 surgical residents, and 1 surgeon receiving training on each of the models and again during their posttraining evaluation session. Five MIS surgeons then assessed the evaluation session performance. For each simulation, we asked them to rate overall competence (COM) and four skills: clinical judgment (respect for tissue) (CJ), dexterity (economy of movement) (DEX), serial/simultaneous complexity (SSC), and spatial orientation (SO). We computed intraclass correlation (ICC) coefficients to determine the extent of agreement (i.e., reliability) among ratings. RESULTS: We obtained ICC values of 0.74, 0.84, and 0.81 for COM ratings on LH, LC, and LA, respectively. We also obtained the following ICC values for the same three models: CJ, 0.75, 0.83, and 0.89; DEX, 0.88, 0.86, and 0.89; SSC, 0.82, 0.82, and 0.82; and SO, 0.86, 0.86, and 0.87, respectively. CONCLUSIONS: We obtained very high reliability of performance ratings for competence and surgical skills using a mechanical simulator. Typically, faculty evaluations of residents in the operating room are much less reliable. In contrast, when faculty members observe residents in a controlled, standardized environment, their ratings can be very reliable.
