Perceptual and adaptive learning modules (PALM's) provide a large number of visual examples for evaluation and accommodate to learner performance by actively adjusting the module parameters.
We developed a module for discriminating 5 inflammatory reaction patterns using the Novel Diagnostic Educational Resource (NDER) platform. The module included a 20 question pre-test, a 200 question training section, and a 20 question post-test. During the pre-test and post-test, images were displayed for an indefinite period of time with no feedback given. In the training section, images were displayed for a duration inverse to learner performance, and after submitting their response learners were immediately shown the correct answer. The performance of module participants was compared to a control group who completed pre-test and post-test only.
26 pathology and dermatology residents completed the module and were included in analysis. Pre-test and post-test scores showed an average increase of 17.1 percentage points (95% CI 13.0 to 21.2, < 0.001). When performance on pre-test and post-test was compared between the module and control groups, module group performance increased more than control group performance by an average of 10.1 percentage points (95% CI -2.5 to 17.8, = 0.0119). 84% (37) of participants found the module somewhat useful or very useful and 68% (30) of participants would be pretty likely or very likely to recommend to another trainee.
Our findings validate the use of NDER for teaching inflammatory reaction patterns. Participants generally had favorable feedback regarding the interface and teaching potential of the module. Including a late re-test as part of the module would be beneficial in further validating future iterations. Next steps include optimizing module performance and developing module content for more advanced learners.
感知与适应性学习模块（PALM's）提供大量视觉示例用于评估，并通过主动调整模块参数来适应学习者的表现。
我们使用新型诊断教育资源（NDER）平台开发了一个用于区分5种炎症反应模式的模块。该模块包括一个20道题的预测试、一个200道题的训练部分以及一个20道题的后测试。在预测试和后测试期间，图像会显示一段不确定的时间且不提供反馈。在训练部分，图像显示的时长与学习者的表现成反比，并且在学习者提交答案后会立即显示正确答案。将模块参与者的表现与仅完成预测试和后测试的对照组进行比较。
26名病理学和皮肤科住院医师完成了该模块并纳入分析。预测试和后测试分数平均提高了17.1个百分点（95%置信区间为13.0至21.2，P<0.001）。当比较模块组和对照组在预测试和后测试中的表现时，模块组的表现比对照组平均提高了10.1个百分点（95%置信区间为 -2.5至17.8，P = 0.0119）。84%（37名）参与者认为该模块有点有用或非常有用，68%（30名）参与者非常可能或很可能会向其他学员推荐。
我们的研究结果验证了使用NDER教授炎症反应模式的有效性。参与者对该模块的界面和教学潜力普遍给予了积极反馈。将后期重新测试作为模块的一部分将有助于进一步验证未来的迭代版本。下一步包括优化模块性能并为更高级的学习者开发模块内容。
