วิทยาการคำนวณ ม.4 ชุดที่ 2

The students benefit the most from using computers in the field of education, knowledge, and practical application. Computers provide a wealth of resources and information that can enhance learning and expand knowledge. They also allow students to practice and apply what they have learned through various software and applications. Overall, computers greatly contribute to the educational development of students.

The given answer states that "เป็นการคิดเหมือนหุ่นยนต์" (thinking like a robot) is an incorrect explanation for the concept of computational thinking. This implies that computational thinking does not involve thinking like a robot or following a set of predefined steps like a robot would do. Computational thinking is about problem-solving using logical and algorithmic thinking, abstraction, decomposition, and pattern recognition, which are skills that both humans and computers can understand and apply.

The principles of computational thinking can be applied to all of the given situations. In searching for products in a department store, computational thinking can be used to organize and categorize the products, making it easier to locate them. When planning to open a food stall at a school festival, computational thinking can be used to determine the optimal menu and pricing based on factors such as cost, demand, and available resources. In calculating statistics for football players, computational thinking can be used to analyze and interpret data to assess their performance. Therefore, the correct answer is that computational thinking can be applied to all of the given situations.

This answer suggests that the focus is on the importance of the problem without considering unnecessary details that are not relevant to any specific idea.

The correct answer is "แนวคิดการออกแบบขั้นตอน" (the idea of designing a step-by-step process). This answer aligns with the concept of problem-solving through a systematic approach that involves breaking down the problem into smaller steps and designing a process to solve it. The other options, "แนวคิดเชิงนามธรรม" (abstract thinking), "แนวคิดการแยกย่อย" (subdivision thinking), and "แนวคิดการจดจำรูปแบบ" (pattern recognition thinking), do not specifically refer to the idea of designing a step-by-step process.

The given answer correctly identifies "แนวคิดการออกแบบขั้นตอน" as the concept of designing a step-by-step process to solve a problem. This concept involves breaking down the problem into smaller, manageable steps and designing a systematic approach to address each step.

To get to Jatujak Station from Central Ladprao, the person should take the red line bus number 1 to Siam Square, and then transfer to the green line bus number 3 to Jatujak.

The correct answer is "ไทย". This is because Thailand has the highest average daily internet usage in the world.

The correct answer is "แนวคิดเชิงนามธรรม" because it focuses on the importance of the problem without paying attention to unnecessary details. This approach emphasizes the abstract and conceptual aspects of the problem, rather than getting caught up in specific details or steps. It allows for a broader understanding and analysis of the problem, which can lead to more effective solutions.

The question asks for the information that is not necessary to solve the problem. The necessary information is the number of lines to be drawn, the points, and the table of lines. The answer "เส้นตาราง" (table of lines) is not necessary to solve the problem.

The question asks which option does not align with the steps of problem definition. The first two options, "วิเคราะห์ความเป็นไปได้และวางแผน" (Analyze possibilities and plan) and "จัดทำเอกสารการวางแผนการดำเนินงาน" (Prepare documentation for the project plan), both align with the steps of problem definition, as they involve analyzing and planning. However, the third option, "ไม่สามารถปรับปรุงแก้ไขแผนการดำเนินงานได้" (Unable to improve or modify the project plan), does not align with the steps of problem definition, as problem definition typically involves identifying and addressing issues or areas for improvement.

The question asks for the answer that is not a sub-skill of computational thinking. "แนวคิดเชิงรูปธรรม" (abstract thinking) does not fall under the category of computational thinking, which involves problem-solving, algorithmic thinking, pattern recognition, and decomposition. Abstract thinking refers to the ability to think conceptually and understand complex ideas, but it is not directly related to computational thinking.

The answer "การแยกแยะปัญหา" directly translates to "problem decomposition" in English. This concept is related to the idea of breaking down a complex problem into smaller, more manageable sub-problems. By doing this, it becomes easier to understand and solve the problem as a whole. Therefore, this answer aligns with the concept of problem decomposition.

The shortest route from the school to home while passing by a bakery and choosing only shaded streets is: school -> bakery -> library -> home.

The statement "เน้นการใช้เทคโนโลยีมือถือ" (emphasis on the use of mobile technology) is not one of the three main areas of knowledge in computer science. The three main areas of knowledge in computer science are computational thinking, appropriate use of technology, and integration with other disciplines.

Based on the given conditions, the shortest route from the school to home would be to pass by the bakery and choose only the streets with shade. However, there is a construction blocking the path from the bakery to the library. Therefore, the only available option is to take the longest route, which is 2500 meters.

The correct answer is "กระบวนการคิดเพื่อแยกสาระสำคัญออกจากรายละเอียด" which means "The thought process to separate important information from details." This answer aligns with the concept of abstract thinking, which involves the ability to analyze and extract key ideas or concepts from a larger set of information or details. It demonstrates the cognitive ability to focus on the essential aspects and disregard irrelevant or less significant information.

The necessary information to solve the problem of providing directions to Jor Dan station at Eden Mall would be the location of the station. This information is crucial in order to guide the foreigner to the correct destination. The other information provided, such as the bus routes and their respective distances and prices, may be helpful for general knowledge but not directly relevant to solving the problem at hand.

ข้อนี้กล่าวถึงขั้นตอนการวิเคราะห์ระบบ โดยกล่าวว่าในขั้นนี้ไม่จำเป็นต้องระบุวิธีการทำงาน ซึ่งเป็นคำตอบที่ถูกต้อง เพราะวิเคราะห์ความเป็นไปได้และวางแผนไม่ได้กำหนดวิธีการในการทำงาน แต่เป็นขั้นตอนที่ใช้ในการทำความเข้าใจกับระบบงาน และมีขั้นตอนย่อย 2 ขั้นตอนคือ สัมภาษณ์ผู้ใช้งาน และวิเคราะห์ปัญหาและความต้องการ ซึ่งเป็นข้อที่ถูกต้องตามเนื้อหาของข้อคำถาม
