Before I elaborate on my point of view, I will firstly try to set those conservative professors’ mind at rest. With electronic devices incorporated into the classroom, students’ attention may indeed be distracted. As they are searching for references or submitting reading notes on their tablets, a new window involving interesting yet irrelevant contents may pop up, attracting students to spend minutes or even hours exploring them. In the end, nothing would be achieved. Worthy of mention is also the eyesight impairment, which chiefly results from the habits of staring at the screens over long periods of time. However, those problems shouldn’t be a concern anymore. The technology is now so developed that it can intervene when necessary. For example, parental control mode can be activated to limit students’ access to certain sites or applications when they are studying. Not only that, it can also restrict students’ using time, and specifically, the devices may be automatically switched off every two hours to prevent students’ from forming sedentary habits.

Doubt removed, we are ready to talk about the benefits of electronic devices in education, and the primary one must be an easier way to understand new knowledge, usually obscure at first. Compared with traditional methods like the use of blackboards and old school black and white projectors, electronic devices, namely tablets and laptops, employ true-to-life audio-visual presentation. This is a major advantage because students are technologically-enabled to appreciate abstract concepts in a more vivid way, which largely facilitate learning. My personal experience is a telling example of this. In my Biology class, by reading the descriptions of the sea otter on textbooks, we gained little understanding towards them, not to mention that the lengthy text was a real bore. Things were different when we watched a short video on our tablets. Within few minutes, we, fully absorbed by it, basically acquired all essential information about this animal, like its habitats, looks, dietary choices and predators.

Another obvious advantage of electronic devices lies in its sandwich-like portability. With knowledge stored in portable devices, students do not have to carry heavy loads of textbooks to here and there. This allows them to utilize spare minutes, particularly time spent in waiting for the bus or meals, to memorize several vocabularies or review some formulas. Over time, their knowledge-retention will be enhanced.
重点词汇：
* sandwich-like portability 像三明治一样便携的
* knowledge-retention 知识记忆
