我的AI新搭档丨④ AI走进课堂 赋能教学新活力_我的网站

A |     冀时新闻报道 智慧课堂、AI助教、个性化的学习路径……随着人工智能应用场景不断拓展，传统教学模式正被打破。    Vladimir Putin has prepared a cunning new “raw materials trap” relying on Bolivia’s fledgling lithium mining industry, with the trap expected to “snap shut” and leave the West again dependent on Russia for its raw material needs, Welt contributor Tobias Kaufer fears.,Pointing to the Latin American nation’s massive, untapped deposits of lithium, Kaufer expressed concerns over Russia’s interest in helping Sucre tap these resources, which are crucial for the production of batteries for electric vehicles.,According to the US Geological Survey, Bolivia’s proven lithium reserves are the largest in the world, with the country’s 21 million tons ahead of Argentina and Chile (which have 19 and 9.8 million tons-worth of reserves, respectively, and together account for more than 30 percent of global lithium output).,“Those with access to the deposits can have a say in the commodity’s prices and availability. Russia apparently has particularly good chances in Bolivia at the moment,” Kaufer wrote. For Europe, he warned, Moscow’s success in the lithium ‘poker game’ would make the commodity another area where the EU depends on Russia, just like with oil and gas.,Russia’s success will be contingent on “the outcome of the Bolivian political crime thriller,” the contributor stressed, pointing to the raging struggle between President Luis Arce, a member of former president Evo Morales’ Movement for Socialism party, and right-wing forces backed by the US attempting to overthrow leftist forces.,Ex-Bolivian President Jeanine Anez Sentenced to 10 Years in Prison Over 2019 Coup11 June, 01:54 GMT,“This is where Russia comes in. Morales is considered a clear supporter of Vladimir Putin,” Kaufer wrote, recalling the former president’s calls for an “international mobilization to stop the interventionist expansionism of NATO and the United States” in March following the escalation of the crisis in Ukraine, and years of efforts by Sucre to shore up ties with Moscow during his presidency.,“If Moscow now succeeds in supporting the socialist’s return to power, the path to the lithium deposits would be clear. At the very least, Morales could urge President Arce to sign a deal with the Russians,” the Welt contributor believes.,Rosatom, the Russian state nuclear giant, has expressed interest in helping Bolivia tap its lithium riches, and is one of six companies which have applied for their development. Others include Lilac Solutions (a US-based start-up with investments from BMW and Bill Gates’ Breakthrough Energy Ventures), Chinese battery giant CATL, and three other Chinese companies.,Along with its interest in Bolivia’s lithium, Rosatom has teamed up with Norilsk Nickel to mine for lithium ores in Russia’s Murmansk region. Last year, the company also announced plans to build a major lithium ion cell manufacturing facility in Kaliningrad, with the ambitious project hoping to begin churning out up to 4 GWh worth of batteries, or about 0.5 percent of total global demand, by 2024.,Morales' Legacy: Bolivian Joint Nuclear Project With Russia's Rosatom Unique for Latin America10 June 2021, 16:53 GMT。

B | 系列报道《我的AI新搭档》，今天一起走进课堂看一看。本台记者 杨晨曦：还记得大气运动、地转偏向力这些抽象又难懂的地理知识点吗？以前老师在黑板上画的时候，是不是很难形成一个立体的空间思维？最后我们还是要靠死记硬背。那么，像这种传统地理课堂的学习痛点该如何破解呢？今天我们就来到了衡水中学，看看在AI的赋能下，这里的课堂发生了哪些改变？眼前这个能360度旋转、动态演示的3D地球，是90后地理老师朱月和AI技术老师花了一周时间"磨"出来的。学科老师梳理教学思路、明确功能需求，AI技术老师借助大模型制作专属立体课件，将课本里那些抽象难懂的空间变化直观呈现，让学生更容易理解吸收。衡水中学学生 李瑾瑜：我觉得像它那个可以自由旋转、可以自己选的模式让我印象最深刻。衡水中学学生 郑慧心：我觉得它让那种课本上的知识就是变得活起来了，不仅提高了这个趣味性，然后还提高我们学习的效率。

C | 衡水中学地理老师 朱月：在做这个的时候也花费了很大的心思，比如说我们的这个灯光、太阳光线，我们要展示的内容是什么、呈现的效果是怎样的，技术老师也给了很大的一个支持。这样生动的交互式课件，是依靠各班标配的智慧黑板呈现的，它也是人工智能走进课堂的重要入口。智慧黑板接入了学校自主开发的AI应用与创新平台，课前老师可以借助星火教师助手生成课件，课中能支持互动展示、录制课堂实况；课后，通过AI自动分析这节课的目标达成度、学生互动情况，可以为老师生成一份"课堂报告"。衡水中学地理老师 朱月：我们可以观看我这节课的一个学习目标的达成度，学生的一个反馈情况或者是我们课堂上师生的一个互动情况，在我下一次课的时候，我就能够更加精准地，也能够个性化地对于学生来做一些辅导。课堂教学提质的同时，人工智能也帮老师省去了大量机械重复的课后工作。

D | 有着18年教学经验的英语老师，依靠校内的智能批改系统，彻底改变了传统英语作文的批改模式。衡水中学英语老师 黄玉春：平时我们要批50多份作文的话，至少得几个小时的时间，但是现在几秒钟就能出来了，而且对学生的词汇、语法，它的批改准确率还是很高的。比如说我们班两个同学，它这个AI阅卷21分最高分，老师自己在阅卷的过程中，确实也是达到了23分、22.5分这样的一个维度，对于师生来说都是一种提质增效吧。

E | 智能批改系统会从语法、篇章结构等多个维度给出修改建议，还能为每位学生定制专属写作小练，实现精准培优补弱。衡水中学学生 胡茁彤：就是一些很普通的单词，它能给我反馈一个更高级的词汇，来让这个人物的形象更加立体化，感觉自己作文的内容有了明显的一个优化。作为我省生成式人工智能应用试点学校，衡水中学已经实现AI教学全覆盖，学校教师AI工具使用率达100%，备课效率提升40%，批改效率提升45%。推动人工智能与教育深度融合，省教育厅联合多部门印发了加快推进教育数字化实施方案和"人工智能+教育"行动计划，不断深入推进国家智慧教育平台全面深化应用试点，目前累计注册用户超1049万，用户规模稳居全国第三。

F | 省教育厅科学技术处副处长 王欢：目前，我们在全省遴选了67个省级人工智能教育基地、100所中小学人工智能创客教育试点校和60所人工智能应用试点校，围绕备课、授课、学情管理等全链条，探索人工智能应用路径。未来，我们将持续扩大试点覆盖面，以人工智能技术助力全省基础教育优质均衡发展。
