text: Would you able to do the right thing when there are not rulers taking a class? Electronics devices are the most powerful and useful tools that help us nowadays like cellphones, smartwatch and computers. However, many students are using electronic devices in the wrong way. For example, students that are taking online classes from home, they don't have rulers and they are using their phones to watch movies or texting with friends. This steal the students concentration, while they are taking the online classes. This can not happen during a normal day of school because teachers do not allows students to use electronics devices during class time. But students do not have the same rulers at home that teachers makes at school. This not benefit the knowledge of the students at home.
