Preparation of tests and student's assessment by the instructor are time consuming. We address these two tasks in neuroanatomy education by employing a digital media application with a three-dimensional (3D), interactive, fully segmented, and labeled brain atlas. The anatomical and vascular models in the atlas are linked to Terminologia Anatomica. Because the cerebral models are fully segmented and labeled, our approach enables automatic and random atlas-derived generation of questions to test location and naming of cerebral structures. This is done in four steps: test individualization by the instructor, test taking by the students at their convenience, automatic student assessment by the application, and communication of the individual assessment to the instructor. A computer-based application with an interactive 3D atlas and a preliminary mobile-based application were developed to realize this approach. The application works in two test modes: instructor and student. In the instructor mode, the instructor customizes the test by setting the scope of testing and student performance criteria, which takes a few seconds. In the student mode, the student is tested and automatically assessed. Self-testing is also feasible at any time and pace. Our approach is automatic both with respect to test generation and student assessment. It is also objective, rapid, and customizable. We believe that this approach is novel from computer-based, mobile-based, and atlas-assisted standpoints.
教师准备测试和对学生进行评估非常耗时。我们通过采用一种数字媒体应用程序来解决神经解剖学教学中的这两项任务，该应用程序具有三维（3D）、交互式、完全分割且有标注的脑图谱。图谱中的解剖和血管模型与《解剖学名词》相关联。由于大脑模型是完全分割且有标注的，我们的方法能够自动且随机地从图谱中生成问题，以测试大脑结构的位置和命名。这通过四个步骤完成：教师进行测试个性化设置、学生在方便的时候进行测试、应用程序自动对学生进行评估以及将个人评估结果传达给教师。为实现这种方法，开发了一个基于计算机的带有交互式3D图谱的应用程序以及一个初步的基于移动设备的应用程序。该应用程序有两种测试模式：教师模式和学生模式。在教师模式下，教师通过设置测试范围和学生表现标准来定制测试，这只需几秒钟。在学生模式下，学生接受测试并自动得到评估。随时进行自我测试也是可行的，且可以按照自己的节奏进行。我们的方法在测试生成和学生评估方面都是自动的。它还具有客观性、快速性和可定制性。我们认为，从基于计算机、基于移动设备以及图谱辅助的角度来看，这种方法是新颖的。
