A keyterms glossary for OCR GCSE Computer Science Component 2 Algorithms and Programming

This lesson is written in a flipchart created for use with Active Inspire programming. This is a lesson that I used to teach the children in my class about algorithms and programs in computing. It is an unplugged lesson, no computers required! It explains how coding works in a child friendly way. I used it with Year 4 at the beginning of our coding topic.

This resource can be used for year 8 for National and IGSCE British curriculum.It is the starting of introducing programming through turtle graphics in python. Students start with turtle and then enter into main python programming.

Based around an introduction to algorithms, a total of 5 lessons are included in this package. Aimed at GCSE Computer Science, the 5 lessons are aimed at promoting an introduction to algorithms using decomposition. Every lesson comes complete with a teachers PowerPoint, iterative starter activities, lesson resources and an ‘Independent Learning Time’ section (this is aimed at allowing students to work independently to consolidate their understanding). Answers to flowchart and pseudo code tasks are included on the PowerPoints. Lesson 1: Introduction to algorithms using flowcharts, starts off with basic flowcharts based on easy scenarios and builds up to looking back at sound storage and representing this process as a flowchart. Lesson 2: Looking at more complex flowcharts to represent algorithms, focusing more on selection and iteration within algorithms. Independent Learning Activity includes exam questions for students to decompose problems and represent as flowcharts. Lesson 3: The focus of this lesson is to allow students time to work independently at solving complex algorithms as flowcharts. Using sequencing, selection and iteration a range of exam questions are included. Class activities are included beforehand to recap the learning of flowcharts. Lesson 4: An introduction to pseudo code - links the understanding of what pseudo code is to Python code which students may have come across beforehand from their NEA. Different examples of how code should be constructed are included. Several flowcharts are included on the PowerPoint which students then need to turn into pseudo code. Sequencing and selection are focused upon in this lesson. Lesson 5: Developing students understanding further using sequencing, selection and iteration. WHILE loops are demonstrated of how to construct a loop in pseudo code. Students will spend their time working on problems and trying to decompose these into pseudo code. Extension questions are included for the HAL students / students needing extra or more challenging work.

This flowchart shows the links between fixing errors and resilience and also that repeated practice leads on to mastery, the more programming is practiced, they better you will get! The flowchart algorithm can be used in classes as a discussion point and a display. The embedded graphic can be resized, printed, cut-out and stuck into exercise books as a reminder that making mistakes is OK, normal and part of the programming cycle.

Learners are introduced to theory (including mathematical concepts) , design and programming using VB.NET and Python. An exciting and in-depth look at Binary Search algorithm as used in computer programming. 2-6 hours of lessons. The resource also comes complete with VB.NET project files and Python scripts. This is suitable for A Level Computing or any other Level 3 computing course. Can also be used for GCSE computing. 40 Page detailed handout containing theory, explanations and code listings. This is a self-contained learning material and can be given to students who can then work independently. Can be used for 2-6 hours of learning. Alternatively handouts can be used by teacher to guide students step by step depending on ability. The document is organised into two main sections: Section 1 - Learners are introduced to the theory underpinning Binary Search. Learners create a number guessing game in VB.NET / Python to help understand the concepts behind Binary Search. This is very useful for beginners new to algorithms. Program teaches, selection and iteration. Typically section 1 can be used for a 2 hour lesson and learners enjoy creating the program and learning about the theory behind binary search. Learners understand how Binary Search works . Learners then create a Binary Search program in VB.NET / Python. Learners use Arrays and learn selection and iteration. There is an advanced implementation using Lists which can be used to introduce lists, sub procedures and functions. Typically section 2 can be used for a 2 hour lesson. The handout comes with all the Microsoft Visual studio 2013 projects created using VB.NET and Python script files created using IDLE. There is a stronger emphasis on VB.NET. There are 7 VB.NET projects associated with this handout. Two of these are for teacher use but learners can implement these also in addition to the 5 other projects. There are 2 Python scripts.

Suitable for GCSE or A Level Computing or any other Level 3 computing course. This is a self-contained learning material and can be given to students who can then work independently. Can be used for 1-3 hours of learning.

This lesson covers Algorithms used in programming. This does not include a lesson plan, but will distribute for free as i used resources from a colleague.

Programming algorithms for drawing shapes In this programming activity, students will use the programming language Logo to understand and create algorithms for drawing shapes. Through creating their own unique shapes via algorithms, students will see their code come to life on screen. This is one of a set of resources developed to aid the teaching of the secondary national curriculum, particularly KS3. It has been designed to support the delivery of key topics within maths, engineering and computing. Activity: Programming algorithms for drawing shapes The first part of this activity is intended to encourage students to examine a sequence of instructions, look for a pattern, and explain this pattern. The next problem asks the students to continue the pattern, making deductions about how the pattern will continue. Students are then challenged to produce a set of instructions for drawing different shapes before trying some designs of their own. They will be encouraged to use an online logo app like Papert to try out their instructions. Problem-solving questions will stimulate students to identify and extend a sequence, requiring reasoning and proof. The engineering context Algorithms form the backbone of many engineering processes, from automation and improving efficiency to data analysis and problem solving. As such, learning about algorithms prepares students for more advanced engineering studies. Pythagoras’ theorem and trigonometry are fundamental in multiple engineering fields such as civil engineering for structural design, electrical engineering for signal analysis, and mechanical engineering for understanding dynamics and mechanisms. Suggested learning outcomes This lesson plan aims to cover potential GCSE content such as identifying and explaining patterns and sequences, understanding the exterior angles of shapes, and applying Pythagoras and trigonometry. In the process, students will also develop key problem-solving skills as they predict sequences, work out instructions, and discuss their reasoning. This activity will also give students a deeper appreciation for the role of algorithms in our daily lives.

This 6-week unit of work enables your learners to design, develop, test and programme computer-controlled electronic systems for a superhero vehicle alarm. While these lessons in this complete series are designed for you to use with your school’s Crumble and free Crumble programming software (google - ‘Crumble programming’ it is very similar to Scratch), all activities can be adapted to work with whatever physical computing resources you have. The following national curriculum objectives are covered over the 6 weeks: Design use research and develop design criteria to inform the design of innovative, functional, appealing products that are fit for purpose, aimed at particular individuals or groups generate, develop, model and communicate their ideas through discussion, annotated sketches, cross-sectional and exploded diagrams, prototypes, pattern pieces and computer-aided design Make select from and use a wider range of tools and equipment to perform practical tasks [for example, cutting, shaping, joining and finishing], accurately select from and use a wider range of materials and components, including construction materials, according to their functional properties and aesthetic qualities Evaluate investigate and analyse a range of existing products evaluate their ideas and products against their own design criteria and consider the views of others to improve their work Technical knowledge understand and use electrical systems in their products [for example, series circuits incorporating switches, bulbs, buzzers] apply their understanding of computing to program, monitor and control their products. All resources are listed here and are referenced in the lesson plans. A great unit that is easy to understand and teach to your class. This unit has been intentionally planned to mainly cover the last national curriculum objective apply their understanding of computing to program, monitor and control their products as I struggled to find a unit of work that could help teach teachers before they then delivered this to children. Crumble micro-controllers have been used due to their affordability and ease of use with the teaching and learning of this unit of work. They are avalible at: https://redfernelectronics.co.uk/shop/ (You only need the starter kit for this planning)

This “Algorithms and Programming” unit is designed for Key Stage 2 students, which is based on the national curriculum. The unit aims to introduce students to the concepts of algorithms, and how they are used to solve problems. It also covers the basic concepts of programming, such as variables, loops, and conditionals. Additionally, it provides an opportunity for students to use a visual programming language to create simple programs, and develop debugging skills to identify and correct errors in their programs. Each lesson includes interactive activities, group work and practical tasks and each lesson has a specific learning objective. The unit concludes with a final project where students will be encouraged to be creative and innovative as they apply what they’ve learned. Assessment throughout the unit is formative and summative, providing students with regular feedback and an opportunity to showcase their final project at the end.

This assessment test allows you to assess your pupils against the national curriculum specification for Python programming. It should be used at the end of Key Stage 3 as a summative assessment rather than as a formative assessment. The national curriculum specifies that by the end of Key stage 3 pupils should have been taught to “use two or more programming languages, at least one of which is textual, to solve a variety of computational problems; make appropriate use of data structures (for example, lists, tables or arrays); design and develop modular programs that use procedures or functions (for example, sub programs).” This test allows you to assess if your pupils have met this criteria. It includes a 6 page PDF document which should be printed and given to your pupils to complete under test conditions. There is no practical element to this test and is completed through a written test. This resource also includes a mark scheme to aid the teacher in marking the paper and even includes grade boundaries and descriptions that can assist the teacher when writing pupils’ long reports. Duration: 1 lesson This end of unit assessment does assume the pupils have been taught the following areas: Data types Syntax errors Logical and sequence errors Inputs and outputs Sequence, selection and iteration If…else statements Drawing and understanding flow diagrams Mathematical operators (+, -, * and /) Comparison operators (>, <, >=, <=, == and !=) For loops (count controlled loops) While loops (condition controlled loops) Simple lists and 2D lists (data structures) Sub programs Passing variables between sub programs and the main program Local and global variables FREE BONUS PRODUCT INCLUDED As a special thank you for purchasing this product I am pleased to be able to also include a surprise FREE bonus gift.

These questions are used to help students practice longer Python coding questions that they will encounter in GCSE exams. The pseudocode style where included is based on AQA, and each question comes with a mark scheme showing where marks are scored. Again, this is based around AQA’s mark schemes (i.e. awarding marks for including selection, for example). This set contains 8 programming questions and mark schemes for each. In separate uploads I have the powerpoint used in lessons to help deliver specific lessons which build up towards answering the longer programming questions in this set. The order I used them (with the intent of increasing difficulty as we went along): 1 - Phone Bill Calculator 2 - Note Changer 3 - Swimming Pool 4 - Guessing Game 5 - Substrings and functions 6 - Sports Day (function) 7 - Linear Search Array 8 - Inverting Image (2D array)
