即将到来的5G+AI时代,将如何改变教育行业

发布时间:2019-08-01 09:55浏览量:

伴随新技术的发展,教育的形式也正随之发生变化。互联网技术及在线音视频技术的发展促进了在线教育发展,催生了在线一对一、在线大班课等多种线上教学模式。

在GET2019教育科技文化节上,华为云业务总经理陶志强提到,以信息技术为标志的第三次工业革命,更多是把数据、信息作为资源去开发,释放新的生产力,即让人类拓展工作的领域得到进一步地提升,同时也使得数字化、智能化让各个行业得到受益。

这也正是产业互联网愈加收到重视的原因,技术的发展使得各细分行业的智能化成为可能,而其智能化程度又随着技术发展产生变化。那正在发展的人工智能技术与5G技术又将为教育带来何种变化。

AI+教育具体如何落地

“人类学习和机器学习的共同特点是,都是学习相关规律,总结知识,从而激发出基础的推理能力。”在全球移动互联网大会GMIC上,网易有道技术总监林会杰表示,在AI技术方面,目前为止还是以数据驱动方式,当具备一定的推理和知识的能力,AI能够去辅助人类做一些决策,甚至去替代一些重复性。

具体到教育方面,林会杰表示,希望能够借助AI技术、机器学习办法,从教学练测评各个环节提升他们的效率,改造传统的学习方式。

“这是美好的设想,我们在做的事情,就是希望通过AI+教育的外部辅助,让中间圈层尽可能扩大。 ”林会杰说。他表示,目前AI+教育正在四方面落地应用。

1、AI可提高作业批改效率。

2、通过智能硬件,实现细颗粒度的教学信息数字化。林会杰表示,纯软件的解决方案要借助一些额外的设备,包括手机拍照或高拍仪,网易有道希望硬件能够切入传统场景而非创造新的场景。

3、AI帮助题目数字化。更多需求是面向教育机构和老师本身的诉求,怎么样提升他们纸质化题目入库效率。

4、AI实现辅导技术化。林会杰认为,AI技术跟传统智能硬件以及教育电子设备结合,会有更多想象空间。

事实上,这正是AI+教育企业们涉足的方向,即通过AI技术来提升教学效率,具体切入的领域包括作业批改、口语测评等方面。但与此同时,所有AI+教育方式在具体落地时也都存在一定问题。

AI+教育的核心是数据

林会杰认为,这其中主要原因在于,整个AI+教育中欠缺非常重要的数据环节,学习过程中老师和学生都会积累大量数据,但目前绝大部分数据都是留存于线下,只有将这些线下数据采集到线上,通过不同类型的数据集不断训练AI模型,才能使得AI模型更成熟,更能帮助达成学习中所需的个性化服务。

“如何更好地采集数据、处理数据、从数据中学习更好地规律,是当前整个AI+教育行业的重点。”林会杰说。他表示,AI+教育进程可分为三个阶段,最底部是教育内容数字化、第二层是教育工程自动化,在这两阶段可将传统的线下教学或学习过程中生产的各种数据与线上数据结合,最后时限教学方式智能化做到因材施教。

林会杰解释,具体实现过程为,通过OCR、ASR、文本处理等系列技术,将传统的纸质化材料和内容进行数据化处理和理解。随后,基于抽取理解出来的数据和资源创造更多个性化应用,比如直播课堂中,以数据理解和采集为中心,后续可以提升互动的效率;最后在自适应学习领域,根据丰富的数据辅助,实现更精准个性化推荐。

在5G方面,林会杰表示,即将到来的5G普及也会刷新AI+教育的体验和可能性,首先会更加提升了直播大班课的速度,以往传统大班课直播,延迟甚至会达到5-30s。陶志强也有同样的观点,及借助更流畅的技术,可以让远程真实的场景更加细腻、逼真。
