“早期的多媒体学习看起来像一辆汽车，它是从不同的废料场拼凑起来的，有不同尺寸、颜色、型号和年龄的组件。那是一头杂种。”英国多媒体学习领域的权威唐纳德·克拉克如是说。他指的是早期大量的学习网站，这些网站的音乐和色彩都很吵。视频和动画混合在一起，屏幕上到处都是图形。设计者们很喜欢它，但用户一开始会感到困惑，然后会分心，最后他们几乎没有学到什么。到目前为止，在BMJ学习，我们已经错误的多媒体学习的一个目的-你不需要宽带使用网站。文本仍然非常有用有经验的读者可以以每分钟300字的速度阅读，但每个人都可以按照自己的节奏阅读。您还可以快速搜索文本，我们也可以轻松更新文本。不过，我们正在网站上构建更多的多媒体内容。这个月我们发布了一个关于牛皮癣的模块。大约2%的英国成年人患有牛皮癣，我们的模块概述了如何在初级保健中诊断和管理患者。传统上，彩色幻灯片用于支持文本，但在这里，图片是模块的核心。我们向您展示不同类型银屑病患者的图片，然后测试和培训您诊断和管理病情的技能。更多图片使您能够测试您对银屑病一些并发症的了解，例如银屑病关节病和红皮病型银屑病。该模块还提供了最新进展的管理，如维生素D类似物和肿瘤坏死因子阻滞剂的作用。
“Early multimedia learning looked like a car that had been cobbled together from different scrap yards with components of different sizes, colours, models, and ages. It was a mongrel beast.” 1 So said Donald Clark, a leading authority in multimedia learning in Britain. He was referring to the early flood of learning websites that had loud music and equally loud colour. Videos were mixed with animation, and graphics popped up all over the screen. The designers loved it, but users were at first bemused and then distracted, and in the end they learnt little. So far at BMJ Learning, we have erred on the side of multimedia learning for a purpose—you don’t need broadband to use the site. Text is still very useful—experienced readers can read at a rate of 300 words a minute, but everyone can read at their own pace. You can also search text quickly, and we can easily update it. However, we are building more multimedia content on the site. This month we have published a module on psoriasis. About 2% of UK adults have psoriasis, and our module outlines how to diagnose and manage patients in primary care. Traditionally, colour slides are used to support text, but here the pictures are at the core of the module. We show you pictures of patients with different types of psoriasis and then test and train your skills in diagnosing and managing the condition. Further pictures enable you to test your knowledge of some complications of psoriasis such as psoriatic arthropathy and erythrodermic psoriasis. The module also gives an update on recent advances in management such as the role of vitamin D analogues and tumour necrosis factor blockers.
