Development and evaluation of an interactive Web-based breast imaging game for medical students

RATIONALE AND OBJECTIVES: The purpose of this study was to develop and evaluate by student survey an interactive computer tool for teaching breast imaging to 4th-year medical students. MATERIALS AND METHODS: An interactive computer game was designed for competitive play between two students or between one student and one of two cyber players. Content was determined from a survey of faculty members in breast imaging, and the survey results were grouped into 10 learning objectives. Pre-existing knowledge of these objectives in 16 4th-year medical students was tested by a quiz. On the basis of the learning objectives, case scenarios and questions were incorporated into the game, which was programmed in JavaScript and available on a Web site. Preliminary and final versions of the game were used for teaching 55 4th-year medical students. A subgroup of 42 students received an informational handout. Student surveys were performed. RESULTS: Mean quiz score for pre-existing knowledge of the learning objectives was 45% (range, 13%-67%). Survey results showed that images contributed to educational value (92%), the Web site was more interesting to students than the handout (93.6%), and the Web site provided additional reinforcement of learning beyond that of the handout or lecture (88.8%). Students liked the Web site accessibility (96%), and more than 70% agreed the Web site was also appropriate for other medical specialties. An Internet search identified no other Web-based computer games for medical students. CONCLUSION: Students surveyed found the Web site to be worthwhile, convenient, and applicable to other specialties.     

多媒体技术在皮肤病学教学中的应用

目的 探讨多媒体课件在皮肤病学教学中的应用及效果。方法 以学生皮肤病学实习中最困难的性传播疾病为突破口，建立了完善的、可持续改进的皮肤病学临床多媒体课件，使学生在有限的实习时间内接受大量皮肤病学临床信息，同时结合实习中师生互动的形式为传统的皮肤病学教学提供了有益的补充。结果 调查问卷及教学质量评估的结果均表明，这种教学形式得到了学生的认可，学生考核成绩亦达到了预期效果。结论 本研究为进一步丰富皮肤病学教学的多媒体课件以及提高皮肤病学教学质量奠定了良好的基础。     

产后访视对母婴保健的影响

目的 及时了解产后访视和护理指导对母婴健康状况及母乳喂养的影响。方法 对512例产妇进行产后建库、建册，选派护师以上长期从事妇产科临床护理工作，有专业理论知识，又有临床护理经验的护士按社区工作规定的时间分别在产后3-7d，10～14d及28-30d进行访视。结果 及时了解了母婴健康状况，解决了病人出院后护理支持不足的问题，产妇及其家属给予了充分的肯定，满意度达100％。结论 产后访视和护理指导，有利于母婴的健康教育，使母婴健康得到保障，使母乳喂养的实施得到普及，取得良好的社会效益。

医学院校多媒体教学的优势、问题及对策

该文阐述了医学院校多媒体教学具有内容丰富、感觉真实、重复性强、效果可靠、功能齐全、操作方便的优点,同时存在学习效率不高、激发创造能力不足、过多的取代传统教学方式、课件质量不够高及信息量过大的不足,必须通过提高课件质量、加强教学中多媒体应用,全方位改变学生的学习和思维方式,不断地总结经验,相互交流,促进多媒体教学的发展.     

寻常型银屑病患者的健康指导

寻常型银屑病是一种常见病,其基本损害为表皮有银白色磷屑的丘疹或斑丘疹,皮疹可发生在全身各处,患者自觉有不同程度瘙痒。病程慢性,易于复发,目前尚无根治的药物。临床观察发现,寻常型银屑病的复发率与心理因素,是否合理饮食以及合理用药与否都有直接的关系。因此加强对寻常型银屑病患者的健康指导对控制病情的发展和复发,提高患者的生活质量有重要意义。现将指导内容及护理体会介绍如下。一般资料40例寻常型银屑病患者均为我科2000年5月至2003年月收治的门诊患者,均符合寻常型银屑病诊断标准,男37例,女17例,年龄16岁~65岁,病程3个月~13a。…     

医用基础化学网络课件的研制

Feasibility analysis of a personalized training plan for learning research methodology

OBJECTIVES: To determine the performance in learning clinical research methodology (CRM) by means of the Keller Plan (KP), to assess its impact on attitudes towards research (AR) and to estimate its acceptability. DESIGN: An educational intervention trial was employed with control group (CG) and random assignment. SETTING: The Family and Community Medicine Teaching Unit in Valencia, Spain, 1997. SUBJECTS: Third-year family residents. RESULTS: In the KP both specific written self-teaching material and interactive computer programme were used, focusing on the tutored resident, with compulsory assessments to continue. In the CG a conventional course was followed. Knowledge of CRM and the AR test (previously validated in another study) were measured at the start. Four tests of successive knowledge, time spent studying, tutorials, final AR test and acceptability were conducted. Non-parametric tests were used. Forty (89%) residents participated, 22 were assigned to KP and 18 to CG. Similar basic characteristics, with exception of AR test (medians 55 Keller, 58 control). KP knowledge tests significantly higher (P = < 0.05) than the CG (medians 101, 88) along with time spent studying (medians 53, 23.4 h). There were no significant differences in AR test, although there was an improvement in both groups, significant in KP but not in CG (median increase of 4.5 and 2). Nine residents used and positively assessed the computer programme. Better acceptability was obtained by the KP in overall evaluation, recommendation of the method and learning dynamic. CONCLUSIONS: The KP obtained better knowledge, motivated studying and was positively accepted.     

An integrated approach to senology education: combination of a hypermedia program with a multimedia archive

The aim of this work was to demonstrate the computerized system on senology, which combines a hypermedia application to a multimedia didactical archive, integrated with a radiological information system. These applications have been developed on Macintosch computers using the softwares Supercard and 4th Dimension. The hypermedia application deals with basic principles of anatomy as well as the radiologic semeiology and pathology through different imaging techniques in order to illustrate basic principles. Thus, students can modify their learning pathways and the timing as they wish. Limitations are related to time consumption in preparing the programs and technical difficulties in expanding them. Multimedia archive allows to classify a large number of difficult and uncommon clinical cases, creating an easily updatable teaching file in digital format which considerably improves access to stored image data, also reducing loss of films and film degredation. From initial experiences we conclude that these systems are valid devices in information and up to date for physicians dedicated to the study of breast pathology. Correspondence to: R. Occhiato
