Studying science using smart devices

Ⅰ. The need for learning using smart devices

 1. Social Background
   end. What is the Fourth Industrial Revolution?
      1) The Fourth Industrial Revolution is aimed at a world of intelligent customization through connection, decentralization / decentralization, sharing / opening.
      2) mobilize various technologies such as big data, artificial intelligence, and block chain to build intelligent world
      3) In order to make the intelligence of the customized era, we connect all the contents of the real world to the virtual world, and predict and fit it in the virtual world through big data / artificial intelligence analysis and apply it to the real world
   I. Explanation of terms related to the 4th Industrial Revolution
      1) AI (Artificial Intelligence): The intelligence created from the machine. It refers to the intelligence created by the system, or artificial intelligence, with ideal intelligence in computer engineering. Example: Google's Alpha, Amazon's Alexa
      2) Internet (IOT): A technology that connects sensors and communication functions to objects by connecting them to the Internet. That is, it means a technology for connecting various objects through wireless communication. The artificial intelligence technology that allows users to exchange information with the user through internet,
      3) Cloud service: I store my information in a storage space somewhere on the Internet, and it is a technology that can be called up through various terminals I have when I need it. Among the various cloud computing technologies, services that have been very popular recently. The number of devices that can access the Internet, such as smartphones, tablet computers, and IPTV, has increased significantly, and the number of people with multiple handsets has also increased dramatically. I often see 'where was the last photo I took' There was a situation where you could not know where your content was. After all, as a result of the euphoria, I want to have a store where I can see the equipment I have! It was made for the purpose of.
      4) Big Data: A technology that extracts values ​​from data, including unstructured data sets that are not large quantities or even database types, beyond the capabilities of existing database management tools and analyze the results. The development of Big Data Technology, which is characterized by the generation, collection, analysis and expression of various kinds of large-scale data, makes it possible to more accurately predict and effectively operate a diversified modern society, to provide customized information for individualized modern society members, Management, and analysis, and realizes technologies that were not possible in the past. Thus, Big Data presents the possibility of providing valuable information to society and mankind in all areas including politics, society, economy, culture, and science and technology, and its importance is highlighted
      5) VR (Virtual Reality) and AR (Virtual Reality): Virtual reality refers to a specific environment or situation, or technology itself, that is similar to the reality created by artificial technology using computers, but not actual. Augmented reality is a field of virtual reality. It is a computer graphics technique that combines virtual objects or information into a real environment and makes it look like objects in the original environment. Frequent use in digital media

2. Student characteristics change
   end. Z-generation: means the next generation of the Millennium generation in the United States. Although there is no standard for accurate generation, demographers generally classify generations born from the mid-1990s to the early 2000s to the late 2000s and early 2010 as the Z-generation.
      1) Characteristics of the Z-generation
         - Process information faster than other generations.
         - They are constantly changing, hating textbooks and living in a constantly updated information world.
         - Quickly and efficiently switch between tasks and games. You can distribute them in multiple notes in the background and perform multiple tasks at the same time.
         - They want a more independent work environment and 72% say they want to start their own business someday.
         She is fluent on five screens (TV, phone, laptop computer, tablet and desktop computer).
         - I want short, image-filled "snackable" content. They do not like long descriptions.

      2) Video education through smart devices is helpful for Z-generation.

         - Simple video for short focus
          The average instant concentration of Z generation students is about 8 seconds. The vast amount of information expressed in long sentences is obsolete. The video is a high-level summary of the information and is explained in a simple, video-based way. This information, in turn, encourages high participation by students.

         - Mobility and Accessibility
          Thanks to multiple smart devices, students can access visual information anytime, anywhere. This allows students to get information whenever they want. Because of their accessibility, these videos can be played repeatedly, regardless of location and time. Creators can display the information they want on the video screen and can be played anywhere in the world. This can help students to learn self-directed everywhere.
         - Visual learning
          Adobe (Programmers) announced that more than 50% of students and teachers view "what they see" as the most effective learning experience. Students will be able to get videos and various types of information related to them through search.
         - Simple message
          Students need a small piece of information that they can understand to process information faster and remember it. Videos that exist on the Internet adhere to app concepts that use images, keywords, attractive design layouts, user-friendly interfaces, and simple sentence structures.
         - Easy to update various information and contents
          Internet videos are not bound to topics. The possibilities are endless! Teachers do not have time to use the entire textbook, but they can create or search for appropriate descriptive videos, which can help students to understand content more deeply, significantly reducing their work time. And since most video content is not only recent, but also accessible 24x7, it's easier to fix and update information compared to textbook updates.
