Faculty are often limited in time, knowledge, and resources to develop efficient, effective, and valid computer-based examinations to evaluate students. Our purpose was to develop a web-based pool of standardized National Board of Medical Examiners (NBME)-format, peer-reviewed, and peer-tested questions based on the Alliance of Medical Student Educators in Radiology (AMSER) National Medical Student Curriculum to evaluate the radiologic knowledge of medical students.
Members of the AMSER Electronics Committee submitted questions they had written for their institutions and later developed a 113-question standardized examination. Questions were edited by 24 subspeciality editors and then further edited by the authors to NBME recommendations. Software was developed using commercially available software (www.ExamWeb.com) with extensive modifications and additions following initial deployment. Students take examinations online and receive their scores immediately. Items were validated by identifying those answered >30 times and analyzing the following: number of times deployed, number of times correctly answered, distractor-specific breakdown, difficulty level (P), and point biserial coefficient (rbi).
Radiology ExamWeb (REW) is available online with 3500 registered students from 65 institutions and 1800 active questions. Instructors can create examinations or use "shared examinations" made by another instructor but enabled for other institutions to administer or modify. More than 300 shared examinations have been developed. The AMSER curriculum was converted into database format and crosschecked with question items to ensure that the question pool adequately covered the spectrum of the curriculum. An AMSER standardized examination has been developed and deployed within REW.
REW has provided medical student educators with the means to evaluate students in a systematic way, using a nationally edited and regularly reviewed web-based process.
教师通常在时间、知识和资源方面受到限制，难以开发出高效、有效且有效的基于计算机的考试来评估学生。我们的目的是基于医学学生教育者放射学联盟（AMSER）的国家医学学生课程，开发一个基于网络的、标准化的、美国医师执照考试委员会（NBME）格式的、同行评审和同行测试的问题库，以评估医学生的放射学知识。
AMSER 电子委员会成员提交了他们为自己的机构编写的问题，后来开发了一个 113 个问题的标准化考试。问题由 24 名专科编辑编辑，然后由作者根据 NBME 的建议进一步编辑。软件使用商业上可用的软件（www.ExamWeb.com）开发，在最初部署后进行了广泛的修改和添加。学生在线参加考试并立即获得成绩。通过识别回答次数超过 30 次的项目并分析以下内容来验证项目：部署次数、正确回答次数、干扰项具体分类、难度水平（P）和点二项式系数（rbi）。
放射学考试网络版（REW）在线提供，来自 65 个机构的 3500 名注册学生和 1800 个活跃问题。教师可以创建考试或使用另一位教师创建的“共享考试”，但允许其他机构进行管理或修改。已经开发了 300 多个共享考试。AMSER 课程已转换为数据库格式，并与问题项目进行交叉核对，以确保问题库充分涵盖课程的范围。已经在 REW 中开发并部署了 AMSER 标准化考试。
REW 为医学学生教育者提供了一种系统评估学生的方法，使用基于网络的全国编辑和定期审查的过程。
