Educator provides evidence of their understanding of communication and outlines and provides evidence of a lesson that uses technology to support students’ use of communication in learning.
Method Components
What are the 4Cs?
The 4Cs for 21st century learning are Creativity, Critical Thinking, Communication, and Collaboration. They are part of the framework for 21st Century Learning and are designed to support student learning in today’s world and are skills they can use in college and career.
What is communication (and what isn’t it)?
The P21 framework emphasizes effective use of oral, written, and nonverbal communication skills for multiple purposes (e.g., to inform, instruct, motivate, persuade, and share ideas). It also focuses on effective listening, using technology to communicate, and being able to evaluate the effectiveness of communication efforts—all within diverse contexts (adapted from P21). Note that working in partners is a great way to collaborate or build shared understanding but a critical part of communication is sharing with an authentic audience.
Example strategies that use technology to support communication in the classroom:

Host a TED-style conference or showcases for your students to present original ideas on a topic of interest to them to an authentic, external audience. Record and post the videos to a youtube stream.
Provide opportunities to listen and ask questions through back channel tools like Today’s Meet or even Twitter.
Have your students publish their work through blogs, by creating websites, and by building other online resources that are shared with authentic audiences.

The COVID-19 outbreak was triggered in December 2019 in the city of Wuhan, which is in the Hubei province of China. The virus continues to spread across the world. Although the epicentre of the outbreak was initially China, with reported cases either in China or in travellers from the country, cases now are being reported in many other countries. While some countries have been able to effectively treat reported cases, it is uncertain where and when new cases will emerge. Amidst the significant public health risk COVID-19 poses to the world, the World Health Organization (WHO) has declared a public health emergency of international concern to coordinate international responses to the disease. It is, however, currently debated whether COVID-19 could potentially escalate to a global pandemic. In a strongly connected and integrated world, the impacts of the disease beyond mortality (those who die) and morbidity (those who are unable to work for a period of time) has become apparent since the outbreak. Amidst the slowing down of the Chinese economy with interruptions to production, the functioning of global supply chains has been disrupted. Companies across the world, irrespective of size, that are dependent upon inputs from China have started experiencing contractions in production. Transport being limited and even restricted among countries has further slowed global economic activities. Most importantly, some panic among consumers and firms has distorted usual consumption patterns and created market anomalies. Global financial markets have also been responsive to the changes and global stock indices have plunged.

As before, the traditional abrasive polishing is not only widely used, but also is being improved. An optimization of polishing regimes (contact load, tool feed rate and reciprocating frequency) can significantly increase in the durability of titanium alloys by improving the surface stress state [1]. A theoretical model is proposed to optimize the regimes of the tool movement and prediction of the material removal profile [2]. The duration of mechanical polishing can be markedly reduced using a diamond coated tool deposited from the gaseous phase [3] including for polishing aluminium-silicon alloys [4]. An abrasive polishing of brass is also recommended with a gradual transition from wet regime to dry one which provides a removal of abrasive particles from the treated surface [5]. A new polishing method of zirconium dioxide enables to change in the rheological properties of the suspension [6].

Not everyone can freely express their opinions. If they do so, they may face threats or bullying. Anonymity allows them to express their views without compromising their safety & sanity. ... So, anonymity helps people to have a right to privacy.
