Thinking of a computer as an auxiliary brain highlights its strengths and weaknesses One significant advantage is its ability to store vast amounts of information for extended periods For instance, a typical book, which contains less than a million bytes, can be stored on a computer for less than a tenth of a cent This allows you to keep a digital copy of the book for easy access, enabling you to read, search, quote, and share it while adhering to Creative Commons Attribution guidelines Additionally, you can enhance your electronic copy by adding comments and ideas directly into the text, similar to underlining and writing margin notes in a physical book You can also create summaries of important concepts and organize your notes in a convenient file or as a preliminary chapter in the book.
I recommend adopting a systematic approach to online reading by creating a personal electronic library that includes your annotations Utilize the automatic indexing features of your computer to easily locate and retrieve valuable information for future use If you plan to reference any scholarly materials, ensure they are accompanied by proper bibliographic citations, allowing for seamless integration into your papers Additionally, keep electronic copies of your written work, as they may serve as useful references for future projects.
Procedural and Computational Thinking
A computer is a machine designed to efficiently execute detailed instructions known as computer programs Learning to write simple programs is accessible, with many elementary school students mastering languages like Logo or BASIC.
Becoming a skilled computer programmer demands significant problem-solving skills, creativity, education, and training These essential abilities are utilized to create detailed procedures for addressing specific problems or tasks, which are subsequently expressed in a programming language After development, the program undergoes testing to identify and rectify any errors, commonly referred to as bugs.
Modern computer programs are typically created by collaborative teams that include problem analysts, programmers, graphic artists, and testers For instance, a medium-sized project like a graphics-intensive computer game can involve around a dozen professionals working together for over a year In contrast, extensive projects may necessitate teams of hundreds, dedicating several years to completion.
Procedural thinking, essential for computer program development, has evolved into the more comprehensive concept of computational thinking This term now encompasses the collaborative problem-solving efforts between humans and computers As noted by renowned computer scientist Jeannette Wing (2006), computational thinking is pivotal in achieving effective task completion and innovative solutions.
Computational thinking leverages the strengths and limitations of computing processes, whether performed by humans or machines It empowers us to tackle complex problems and design systems collaboratively, which would be unmanageable individually This approach also explores the nuances of machine intelligence, investigating what tasks humans excel at compared to computers and vice versa At its core, computational thinking seeks to define what is computable, a question that remains only partially answered today.
Computational thinking is an essential skill for everyone, extending beyond the realm of computer science It should be integrated into the foundational skills of reading, writing, and arithmetic, enhancing every child's analytical capabilities.
Students need to pay particular attention to the two questions:
• What can humans do better than computers?
• What can computers do better than humans?
Answers to these two questions vary from discipline to discipline and from course to course
Computational thinking emphasizes the collaboration between human and machine intelligence, with each playing a vital role in addressing specific problems and tasks Chapter 4 delves into the dynamics of human and machine intelligence.
