International Hope School Bangladesh Class 9 Subject CS Topic Algorithm Design and Problem-Solving Major Goal Specific Objectives Assessment Timing Text Book/Resources Cambridge-igcse-computer-science Page no. Date: 8th February– 9th March 179-192 A study of techniques for finding solutions to problems through structured programming and step-wise refinement. The objective is to design programs using pseudocode and implement them in an appropriate programming language. At the end of this lesson, the students will be able to: - Understand that every computer system is made up of sub-systems - Be able to use top-down design and structure diagrams - Be able to explain standard methods of solution including pseudocode and flowcharts - Be able to suggest and apply suitable test data - Understand the need for validation and verification checks to be made on input data - Be able to use trace tables to find the values of variables at each step in an algorithm - Be able to identify errors in given algorithms and suggest ways of removing these errors - Be able to produce an algorithm for a given problem Total marks: 40 marks - Class work – 10 marks - Quiz – 20 marks - Homework – 10 marks Total allocated time – 7 periods/classes Theory class/Problem Solving – 5 periods/classes Class work/quiz – 1 periods/classes CT/Unit Test – 1 period/class Period Timing/Phase Methodology Assessment 1 5 mins – Warm up 40 mins – Discussion Introduction about the chapter based on the syllabus Computer system and Sub system - Observation - Oral Resource/ Material - White board - Board work copy 5 mins - Wrap up 5 mins – Warm-up 35 mins- Discussion 2 10 mins - Wrap-up 5 mins – Warm-up 40 mins – Discussion 3 5 mins - Wrap-up Understand that every computer system is made up of sub-system, which in turn are made up of further sub-system Use of library routines and subroutines Top-down design and Structure diagrams Use top-down design, structure diagrams, flowcharts and pseudocode Be able to produce an algorithm for given problem it can be either pseudocode or flowchart Overall summary of the lesson, feedback and wrap up. Warm up and Brainstorming on the previous topic. Standard method of solution Explain standard method including pseudocode and flowcharts with an given example Question/Answer on topic Warm up and Brainstorming on H.W1. Test data Be able to suggest and apply suitable test data for example: Normal data, Extreme data, and Invalid data Validation and verification check Understand the need for validation and verification checks to be made on input data (validation could be- range check, presence check, type check, check digit; verification could be- lookup, length check, format check) Overall summary of the lesson, feedback and wrap up. - Text book - Slides/Videos - Observation Oral Written H.W1 - Observation - Oral - Written - White board Board work copy Text book Slides/Videos - White board Board work copy Text book Slides/Videos 5 mins – Warm-up 35 mins – Discussion Asking question from the previous lesson.
