Learning Objectives: 12.1 Program Development Life cycle Show understanding of the purpose of a development life cycle Show understanding of the need for different development life cycles depending on the program being developed (Including, waterfall, iterative, rapid application development (RAD) Describe the principles, benefits and drawbacks of each type of life cycle Show understanding of the analysis, design, coding, testing and maintenance stages in the program development life cycle. 12.2 Program Design Use a structure chart to decompose a problem into sub-tasks and express the parameters passed between the various modules / procedures / functions which are part of the algorithm design Describe the purpose of a structure chart Construct a structure chart for a given problem Derive equivalent pseudocode from a structure chart. Show understanding of the purpose of state-transition diagrams to document an algorithm. 12.3 Program Testing and maintenance Show understanding of ways of exposing and avoiding faults in programs. Locate and identify the different types of errors: syntax errors logic errors run-time errors Correct identified errors Show understanding of the methods of testing available and select appropriate data for a given method (Including dry run, walkthrough, white-box, black-box, integration, alpha, beta, acceptance, stub) Show understanding of the need for a test strategy and test plan and their likely contents. Choose appropriate test data for a test plan (Including normal, abnormal and extreme/boundary) Show understanding of the need for continuing maintenance of a system and the differences between each type of maintenance (Including perfective, adaptive, corrective) Analyze an existing program and make amendments to enhance functionality

For all Teacher attached a student project for you attention: Please before you solve any pre-release material for students. It is better to let them try to solve it first. please give this project to your student for a period of a month therefore you can measure students progress and attainment. IGCSE Pre- release material for Computer Science paper 2 - Student Project Attached the Pre-release material for paper 2 exams , Please ask the students to open the PDF and watch the video and it will give students a starting point how to solve task 1/2/3 for this year exam. Thank you But before that. student should start attempting pre-release paper 2 for last year May/June 2021, Please ask the student to go straight to slide 11 and do the last year exam paper 2 May/June 2021 , Students will find the questions/answers and the python programming code for task 1 / 2 and 3 . I included python programming code for last year paper 2 exams for task 1/2/3 . Please make sure students practice using last year exam paper 2 before they start solving this year paper 2 . Thank you Ask the students to solve and provide the following three tasks for this year exam: pseudo code and python programming for Task 1 pseudo code and python programming for Task 2 pseudo code and python programming for Task 3

IGCSE (CIE) Computer Science Revision for paper 21/22/23 Part B only with answers

11.1 Programming Basics 11.2 Constructs 11.3 Structured Programming 11.1 Programming Basics Implement and write pseudocode from a given design presented as either a program flowchart or structured English Write pseudocode statements for: • the declaration of variables and constants • the assignment of values to variables and constants • expressions involving any of the arithmetic or logical operators input from the keyboard and boutput to the console. Use built-in functions and library routines Any functions not given in the pseudocode guide will be provided String manipulation functions will always be given 11.2 Constructs Use pseudocode to write: • an ‘IF’ statement including the ‘ELSE’ clause and nested IF statements • a ‘CASE’ structure • a ‘count-controlled’ loop: • a ‘post-condition’ loop • a ‘pre-condition’ loop Justify why one loop structure may be better suited to solve a problem than the others **11.3 Structured Programming ** Define and use a procedure Explain where in the construction of an algorithm it would be appropriate to use a procedure. Use parameters: A procedure may have none, one or more parameters and A parameter can be passed by reference or by value. Define and use a function Explain where in the construction of an algorithm it is appropriate to use a function. A function is used in an expression, e.g. the return value replaces the call. Use the terminology associated with procedures and functions: including Procedure / function header, procedure / function interface, parameter, argument, return value Write efficient pseudocode
