The iMac has been around for more than a quarter of a century. The first iMac burst onto the scene in 1998, and was a huge success, saving Apple's bacon when things were looking bad. Like Dr. Who, the iMac has seen some significant changes over time, with each generation offering something different from the last.

The new M4 MacBook Air might be a great upgrade in performance and pricing, but unfortunately, it’s still far from easy to repair. iFixit has released its teardown results for the latest MacBook, calling it “a mix of good intentions and frustrating limitations that continues to fall short of what consumers deserve in a premium laptop.”

The M3 MacBook Air was one of the best laptops of 2024. With the M4 MacBook Air, Apple has again focused primarily on a chip upgrade, but the basic premise stays the same and as a result, the MacBook Air is unequivocally the best consumer laptop in its category.

Apple reportedly held an all-hands meeting with its Siri team to discuss the "embarrassing" and "ugly" delay of AI-enhanced functionality. Details from the meeting show that this AI voice assistant functionality, which has been heavily advertised through the iPhone 16 marketing campaign, may arrive even later than expected.

Macs used to have no end of gaming options, until about the turn of the century. Since then, gaming on a Mac has been a bit of a joke at Apple's expense. However, in recent years, things have taken a turn for the better, with Apple making many moves that should result in more games coming to its platform,

The Satechi Mac Mini M4 Stand & Hub perfectly fits beneath Apple’s smallest desktop computer adding more front ports and a hidden drive for extra storage. It’s an ideal design for people who need access to USB-A, or, in my case, just want an Apple-like SSD exclosure.

需要板书的线上教学实现方式

自有疫情始,线上就学就是情况严重时延续教学的唯一选择了。此文不谈线上教学的效果,只谈实现方式。之所以现在还谈实现方式,是因为今天消息发出后还有很多同事在实现较好过程的线上教学方面还有不少疑问。

一、软件选择

现在实现线上教学的软件还是比较多的,我就不一一列举了。我们推荐使用的腾讯课堂老师极速版,这是企鹅公司推出的疫情专用版本。软件功能强大,基本可以满足常规上课场景,学生只需要点击教师分享的链接就可以进入课堂学习。教师端支持Win和Mac两种平台,学生可以通过学生版Win桌面版、Mac桌面版、网页版、安卓客户端、iPhone端和iPad端等6种方式在线上课。感兴趣的朋友可以点击上面的链接了解详情,

对于文科教师来说,本来需要板书的内容就少,书写的内容可以提前做成PPT。但是像数理化这种课堂上需要大量板书的学科,教师线上教学的时候还需要配有专门的手写板才能取得较好的教学效果。网上提供的线上教学专用的手写板也不贵,200元左右就可以买到了。我个人觉这种手写板有两个弊端:一是书写效果不是很理想,而且只能在电脑上才看到书写的内容,二是线上教学停止后手写板基本派不上用场。



二、手写实现方式

1、硬件:Win或Mac电脑,iPad平板

2、软件:iPad平板手写软件(随手写、CollaNote)、Airserver(投屏软件,也可以使用其他投屏软件)。Airserver是一款付费软件,支持Win和Mac系统,提供30天的免费试用,一般情况下,30天的时间应该够了,付费的话价格也不贵。PS:也可以网上找TNT。

3、思路:电脑客户端正常上课,需要板书的时候,直接打开iPad的手写软件,通过Airserver把iPad屏幕投屏到电脑,因为电脑的屏幕已经分享给学生了,所有学生也能看到投屏到电脑的iPad屏幕,这时候直接在iPad上书写就可以了。

说明:老版本的iPad只能支持手写,一般场景可以应付了。更高要求的话可能需要更新你的iPad了,2018年开始的iPad支持Apple pencil,可以用笔书写。Apple pencil的价格不低,如果不是精修图片这样的需求,某宝上买个电容笔也是极好的。
