The objective of this course is to equip students with the fundamental thinking skills and practical programming ability needed to analyze real-world problems, design logical solutions, and implement those solutions using computer programming tools. Remember all we do as computer scientist is solving problems using algorithms and computing
What is a Problem?
A problem is any situation, challenge, or difficulty that requires a solution. Problems can occur in daily life, education, business, health, and technology. A problem exists when there is a gap between the current condition and the desired condition. A problem is a situation where there is a gap between the current state and the desired state. Examples: - Forgotten password - Low student performance - Incomplete student records - Delay in salary payment
If students cannot access their examination results because records are missing, that becomes a problem. Problems may be simple or complex depending on the situation. Some problems require immediate solutions, while others may need careful analysis before they can be solved. Understanding the exact nature of a problem is the first step toward finding the right solution.
What is Problem Solving?
Problem solving is the process of identifying a problem, understanding its cause, generating possible solutions, and selecting the best method to solve it. It is a systematic approach used to overcome challenges and improve situations.
Steps in Problem Solving
Problem solving follows a series of logical steps that help in finding effective solutions. Step 1: Identify the Problem: Identifying the problem clearly by understanding what is wrong. You ask what exactly is wrong? Step 2: Analyze the Problem: Analyzing the problem to determine the cause and understand how serious it is. Why did it happen? Step 3: Generate Possible Solutions: This involves generating possible solutions by thinking of different ways the problem can be solved. What are the available options? Step 4: Select the Best Solution: select the best or most suitable solution by comparing the available options and choosing the most suitable or effective one. Step 5: Implement the Solution: implement the solution by putting the chosen method into action. Step 6: Evaluate the Result: evaluating the result to determine whether the problem has been solved successfully or if improvements are needed. Did the solution work? These steps help prevent wrong decisions and ensure better outcomes.
Characteristics of a Good Problem Solver
1. Analytical Thinking: Ability to break problems into smaller parts. 2. Creativity: Thinking of innovative solutions. 3. Persistence: Not giving up easily when faced with challenges. 4. Logical Reasoning: Following clear, rational steps. 5. Attention to Detail: Avoiding errors and spotting inconsistencies. 6. Adaptability: Adjusting solutions when conditions change.
Real-Life Examples of Problem Solving
Long queue in school fees payment ==> Online payment system Missing student records ==> Digital database Examination malpractice ==> CBT examination Poor communication ==> School portal / email
Computing and Problem Solving
Computing is the process of using computers and related technologies to solve problems, process information, and perform various tasks efficiently. It involves the use of hardware, software, data, and human interaction to achieve meaningful results. Computing is not limited to calculations alone; it also includes communication, automation, decision-making, data storage, and information management. In modern society, computing is used in schools, hospitals, banks, offices, industries, and homes. For example, when students use a school portal to register courses or check results, computing is taking place. The goal of computing is to make work faster, easier, and more accurate.
In computing, problem solving is very important because every computer program is created to solve a particular problem. For example, a payroll system is designed to solve salary calculation problems, while a school management system helps solve student record issues. Good problem solving requires critical thinking, logical reasoning, creativity, and proper decision-making. It helps individuals and organizations work more effectively and achieve better results.
In computing, it often involves: - Identifying the problem. - Breaking it down into smaller parts. - Designing an algorithm. - Implementing the solution using a computer program. - Testing and refining the solution.
Core Concepts of Computing
1. Data & Information: Raw facts (data) processed into meaningful output (information). 2. Algorithms: Step-by-step instructions for solving a problem. 3. Programming: Writing code to implement algorithms. 4. Hardware & Software: Tools that enable computing. 5. Networking & Communication: Sharing information across systems. 6. Human-Computer Interaction: How people use and interact with computers.
In summary, computing is about solving problems using technology. A good problem solver combines logical thinking, creativity, and persistence. Real-life applications of computing show its importance in every sector of society.
