computers and software are changing everything vis a vis how computer science is taught or not taught in schools

  • Read about how computers and software are changing everything vis a vis how computer science is taught or not taught in schools (‘What’s wrong with this picture?’, 2015).  Examine the extent to which computer science is changing our world yet schools seem to lag behind in computer education. Suggest how STEM education can change ‘this picture’. Include strategies you would use to convince parents, administrators, and peer teachers of this. make your presentation real by including real class experience.

  • There is need to appraise approaches to teaching computer science in secondary classrooms. This is necessitated by recent developments in technology have changed the learner’s profile and the learning outcomes. Today, with the emergence of higher-order thinking skills and computer literacy skills, teaching through traditional methodologies likely to fail to achieve the learning outcomes (Gokce et al., 2017).

  • Due to the fast developments in Information and Communication Technologies (ICT), many young people are constantly connected to digital devices and the Internet. This has changed the way they receive and process information, and the education system is slowly starting to adjust and explore the opportunities that ICT can bring for students’ learning and development (European Schoolnet, 2016).

  • One of the most intriguing objectives when teaching computer science to students in secondary school is attracting and mainly maintaining their concentration within the limits of the class. In this paper, an empirical study is performed with the support of the “Hour of Code” initiative. The initiative was presented to a number of students as a motivation for teaching computer programming to them. An evaluation of the students’ programming skills is attempted with the aid of a questionnaire and a simple personalization framework is presented in order to adapt to the students’ personal needs.

  • Computers and software are changing everything yet the majority of schools do not teach computer science (‘What’s wrong with this picture?’, 2015). It seems that our education system today is not set up for everyone to participate in the emerging economy and opportunities. Computer science is not widely taught in our schools. The irony is that parents want their children to learn computer science. Our education system clearly needs to evolve to bring computer science to students that want to learn this subject.

  • We live in a rapidly changing technological world. Technology dependence and jobs are increasing but the STEM (Science, Technology, Engineering, Mathematics) workforce isn’t (TEDx Talks, 2016). What if YOU – parents and families – hold the key to the STEM workforce diversity and growth issues? You Can Code! Everyone can code! Let’s setup Workplace Maker Spaces and watch the imagination, creativity, innovation, and collaboration grow. It’s good for you, your kids, your business, your country, and the STEM workforce

    Internet Security: From Stand-alone Computers to Web-based Systems

    For this writing assignment you will create a paper entitled, “Internet Security: From Stand-alone Computers to Web-based Systems”. The contents of the paper will be based on subjects covered in the textbook. The goal of creating this paper is for you to learn more in-depth information about various subjects covered in the textbook.

    From each of the chapters 1 through 8 in the textbook pick one major section that is of interest to you. For each section that you selected, do the following:

    Use the chapter number and the title of the section in the textbook as the title for that part in your paper, for example, “(Chapter 1) Client/Server Computing”. Then in 200 – 250 words, either confirm the information given in the section or add to the information in the section (or both). Find this material by using the references listed in the back of the textbook and by searching on the WWW. Your confirmation or addition of information should be based on primary sources rather than information from other textbooks or from magazine (i.e., web-zine) reviews. Do not use Wikipedia or other such websites as a reference. Also, do not copy/paste sentences from the textbook into your paper.

    Development of computers and the impacts on society through the time

     Write a 4 pages paper on development of computers and the impacts on society through the time. Many use computers to search for information, read, send or receive emails, or even pay bills among others (Morley and Charles 53). Computers have influenced the quality and structure of work and some people believe that they have significantly contributed to the emergence of post-industrial society (Edwards 13). This paper focuses on the development of computers and how they have affected individuals’ lives and activities and the society as a whole.

    The word computer was first used in 1613 to describe a human who performed calculations and this definition remained the same until the end of 19th C when individuals began to realize that machines perform calculations faster and more accurately as compared to humans. The first electronic digital computer introduced in 1950’s used vacuum tubes, followed by the computers that used transistors (Jain 1). Notably, the first computing machine was created by British mathematician, Charles Babbage in 1882 and his great inventions made him to known as the father of the computer. He suggested and started developing the Difference Engine which is believed to be the first automatic computing engine that was able to compute various sets of numbers and producing hard copies of the results. Actually, his idea was not really to create what we refer to as computers but to create a machine that would compute mathematical problems. Babbage was fed up with human errors in computing math problems and so he was focused to come up with an infallible math machine. Later on, he proposed the first general mechanical computer, the Analytical Engine, which became the first machine that resembles today’s modern computers. It could keep data safely and had some features used in today’s computer language. Moreover, basic concepts of the stored program computer were developed during this period (Hyman 164).

    Computer applications that run on desktop and laptop computers have, for a long time, been designed to be driven by dragging and clicking a mouse

    Computer applications that run on desktop and laptop computers have, for a long time, been designed to be driven by dragging and clicking a mouse. With the introduction of tablet personal computers, the trend has shifted toward using touch-based screens. We now have access to touch-based TVs, touch-based monitors, touch-based laptops and touch-based tablets. Touch and multi-touch devices provide end users with the ability to interact physically with an application much more naturally.Imagine that you are the Information Technology Director of a major chain restaurant, and you have been assigned to design a menu ordering application that can run on all devices. Examine whether using a touch-screen monitor, a tablet, or using a mouse to select menu items to place an order would be most efficient. Speculate how employees would interact with these devices and the type of emotional reaction that customers and employees will experience while placing a beverage, appetizer or entrée order.Write a four to five (4-5) page paper in which you:

    1. Differentiate between the interaction types and styles that apply to multi-touch screens and applications running on them.
    2. Determine the conceptual model that you would use when designing a product for your restaurant.
    3. Describe the key analogies and concepts these monitors expose to users, including the task-domain objects users manipulate on the screen.
    4. Determine one (1) utility / tool in an application for touch-based and mouse-drive screens that should be designed with memory retention / recall. Provide a rationale for your response.
    5. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources. You may use the resources above or others of your choosing.
