How do you study each day? You may answer it in one second: have classes at school, take notes and do homework. There are some normal ways. Do they seem a little boring? If so, there are other new ways that can make learning interesting. It’s digital(数字化) learning.
There are three important kinds of digital learning. The first kind is apps(应用). People can download them on their mobile devices(设备). For example, the app Khan Academy(可汗学院) covers many courses such as math, physics, computer science and so on. The other two kinds are social networking services such as weibo and WeChat and websites. Each of them is like your teacher. They help you learn more.
Compared with normal learning ways, digital learning has its good sides. It almost covers everything. More importantly, it’s always updating(更新), which offers students the newest things to learn from. Digital learning can meet different learners’ needs. You can choose what you like to earn. You can also learn at your own speed. If you don’t understand what you have learned at school, you can learn again whenever and wherever you want to.
However, digital learning also has downsides. When you use digital ways to learn, there is little connection with teachers and classmates. As digital learning uses computers or smartphones, watching the screen too long may be bad for your eyes. It is better to take a rest every 20 minutes.

ChatGPT, an AI chatbot tool (聊天工具), has quickly become popular since it came out in late 2022. It can do a lot of things such as chatting, doing translations and even writing codes for a computer program. While it has surprised the world, it has also caused both excitement and worries in teaching and learning.
According to a survey covering over 1, 000 students and 100 educators, about 89% students said they used it to help with homework. About 48% said they used it to finish home tests. And over 50% used it to write an article. 34% of the educators said ChatGPT should not be banned (禁止) in schools and universities. But 66% thought students could not use it.
Now, some universities and schools in New York City have already banned the use of ChatGPT. They are really afraid that the tool could make it easier for students to cheat (欺骗) and be used to spread wrong information. Besides, they think the tool does not build creative-thinking and problem-solving skills, which are important for lifelong success.
However, some people think banning ChatGPT is not smart. Instead of simply banning it, using it can free teachers and students from the simple work so that they can do more creative work. To avoid (避免) cheating, instructions on how to use it in a right way should be given.

【推荐3】Xin Xiaoyong, a physical education teacher at Guangzhou No. 1 Kindergarten, said when he graduated from normal university in 2005, there were already many kindergarten men teachers in Guangzhou, Guangdong province.
“Men teachers are treasured at the kindergarten and we receive lots of care and support,” Xin said.
Though most of the comments on Brother Apple’s exercise videos are popular, he has received some disapproval.
Xin said the gymnastic exercises were too advanced for younger children. “Children age 3 to 6 don’t have a high level of management in their bodies. We cannot overlook the fact of the abilities of the children for being a popular icon,” Xin said.
He encouraged men teachers to show manly physicality rather than just meeting parents’ interests.
Xin said men teachers are expected to be professional and modest. “Lots of handsome kindergarten teachers are good at singing and dancing, but we are just common teachers that provide happiness for children and parents.” he said.
