As mentioned in this article, educators often ignore the inequality in technology. We learned a lot about how to use digital tools to improve our teaching and break down the inequities of original education. However, we have not learned about the inequality that technology itself can bring. The racial, cultural, disability and age injustices mentioned in the article are issues I should be wary of when choosing to use technology to improve my teaching in the future.

I know this learning experience well. As a person who is not good at speaking, we tend to be silent in class. In the process of group discussion and under the impetus of the teacher, it seems possible for us to participate in the class and speak. I think this Progressive Stack approach to discussion is a great teaching method.

This has been a serious problem in many countries' education systems for a long time. In China, students from primary school to high school are preparing for the National College Entrance Examination. Students are always immerse in exercises and memorizing text book knowledges. There's only one way for students to go if they want to get a higher education. Now many Chinese schools have realized the problem of single education and have made changes. But it is challenging and difficult. I think UDL is a good tool for Chinese teachers to use.

I think this highlights the main reasons for using UDL in the educational process. UDL provides a teaching template with purpose, initiative, and flexibility. UDL helps teachers and students remove barriers to teach and learn so that every student has an equal opportunity to learn. We believe this will greatly improve the effectiveness and reach of education.

I think this points out a problem worth reflecting on in teaching. Many teachers understand the usefulness and effectiveness of positive and negative reinforcement in behaviorism and often use it in their teaching. However, some teachers fail to recognize the limits of behaviorism. As mentioned here, behaviorism teaching fails to help students relate knowledge to real problems. Linking theoretical knowledge with reality is the real meaning and goal of education. Therefore, teachers should think more about how to make students connect what they learn with reality and apply it.

I think this is an important point to keep in mind when choosing and using digital tools to aid instruction. Since the purpose of teachers using digital tools is to help students have a better learning experience and improve learning efficiency rather than its counterproductive effect. Searching with a purpose is often twice as effective.

I think this law in Maine is very useful for other states and other countries to learn from. As the name implies, ISP as a service provider should only use customers' personal information in providing Internet services. If this is not the case, then the ISP should let the consumer know and get permission from the consumer. As Jordan mentioned it is an opt-in choice.

That's the question teachers and many professionals should be thinking now that Chat GPT has emerged. Many people sigh that nowadays with such “intelligent and omnipotent” AI, what else can we humans do? Many professions are in danger of being replaced. A friend of mine who studied computer science told me that he felt useless. AI makes things better and faster than he does. He said I should also think about whether I will be replaced by AI in the future, because AI knows more than me and can learn how to care for students. My answer, like this statement, is that while AI can do many things, it is no substitute for humans who can use AI to solve problems and challenges. Teachers are better able to decide which assistive technologies to use to meet the needs of each student. Coders are better able to figure out how to use efficient AI to make better products.

Timely technical support benefits not only students' learning but also teachers' teaching when using tools. I'm thinking of IT department in UMass. When I have problems logging into Spire, when I link to the school network and when I use the iclicker, I know I can turn to the school's IT department for help. They will solve my problem quickly and efficiently. This kind of professional technical support makes my study not hindered by technical problems. I remember when I took some classes, professors would also ask IT for help with computer and screen connection problems or technical problems like microphones and recording. The timely technical support of IT has cleared the way for teachers to teach classes.

A clear guidance is really important. Whenever my teacher or professor starts using a new tool in the classroom, I start to feel uneasy. Because I know I'm going to spend a lot of time learning how to use this tool. In this process, I can only slowly explore on my own. I often feel confused and lost. Such negative emotions have a great impact on my learning enthusiasm in this course. It also makes me less productive. So I really know how helpful it is for students to have a clear guide.

I agree with the view that disability is a social state. This reminded me of how few facilities I saw in public areas in China, such as disabled parking spaces and toilets. But when I came to the US, I saw these facilities almost everywhere. I think the level of care for the disabled shows the actual living standards of a society and a country.

I was blown away by the data. I never realized the huge number of disabled people. This reminds me to always consider the disabled community in my future life and teaching.

Sometimes I can't fully understand the concept when I listen to the lecture. But if the teacher show me a video about it, I get the concept better. Therefore, I think teaching by providing multiple means of representation is more effective. This is because multiple means of representation including visual and auditory better adapted students' different thinking patterns thereby better enable students understand the content.

For today's teaching, it is more important to provide remote co-working software than other functions. At the same time, the benefits of online co-working are not only reflected in its overcoming the difficulties of distance, but also in the improvement of work efficiency. Students can do different jobs on one page at the same time and see each other's work and communicate and revise in time.

This metaphor perfectly solves my confusion about using Twitter Chat. Large amounts of information are arranged in complex forms. I tried to follow every message but it made me tired and discouraged me from keep using Twitter Chat for a long time, even if it was valuable. However, the key point is I can go to there and see the information that are valuable to me when I have time.

Every time when I have questions or get stuck in my homework, I will go online to find the answer or watch the YouTubers "class" instead of asking my teachers. This is because I will be nervous and shame to ask my teachers some questions that might seem like silly. Searching it online makes me feel comfortable and I can always find what I want.

These kinds of convenience, practical, and flexible characteristics of PLNs perfectly accommodate to nowadays learning circumstances which are influenced by the Covid-19, information explosion, and the rise of artificial intelligence. The ability to properly and effectively learn with a PLN is essential for both educators and learners.
