Computational Thinking

This lesson introduces the idea of Computational Thinking. It teaches students the fundamentals that are used throughout the GCSE Computer Science topic. This can be taught to KS3 or KS4 and is the first lesson of six within this package. This lesson covers decomposition, pattern recognition, abstraction and algorithms. The exercises then help students practice their understanding before moving onto flowcharts.

[GCSE+IGCSE] Python Text Adventure Coding Challenge

This is possibly my most favourite piece of work to do with the students. I do it as an end of year activity when they are a bit more confident with the material. We create a zombie survival text adventure game and I have recently updated it to include questions similar to what has been in the recent exam and in the exemplar exam What is covered Local and Global Variables Variable Types Input and Validation Conditional Loops Fixed Loops Arrays Subprogram calls (Functions, Procedures and Pre-defined) Libraries Complex conditions and selection Repetition and Iteration What is included Word document with instructions, task overview and more detail on the activity Student Starting Python file (in zip folder) Teacher completed exemplar file Answer document to questions

[GCSE+IGCSE] Mini Project: Pentathlon

This is another of the mini projects that I get my students to complete in preparation for completing the coursework. Lesson Overview Depending on ability level, we start by completing flow charts and pseudocode to complete the design of the program. I sometimes prepare a complete one, but blank out some of the steps to give to my weaker students. Better students I will give blank designs to and somewhere in between for the other students. At end of this lesson, we look at how the code works In preparation for the next lesson, I get the students to watch the video as a homework task. The next lesson, the students complete the program using their pseudocode / flow charts completed in previous lesson. If they are still struggling, they can watch the video again in class time, as well as me able to wander around and help. Students who are better at coding will easily be able to add more functionality to this project Included Zipped file contains: 2 CSV files required for the project and the completed solution file (1 of the CSV files is the file writing part) Video Support of completing the solution Whilst this is mainly aimed at students, it would be useful PD for any Computer Science teachers who are still struggling to understand the complex programming side of the course What this teaches File Reading from CSV file File writing back to CSV file Storing Data in 2D arrays Functions/Procedures Parameter Passing Complex Functions (Finding Minimum algorithm using 2D arrays) Combining

[GCSE+IGCSE] Mini Course work project with Video and Solution Computer Science

This is a smaller project that uses File Reading, 2D arrays and some manipulation of the data stored in it. A complex project, smaller than a final year project, but building in complexity. Included: 3 solution videos, completed solution file (.py) and zipped (TES doesn’t allow this file type) with the CSV file to access - save these in the same folder, or your program will not work

Computer Science Algorithms Test

This is the test my students complete after they have finished my Algorithms and Problem Solving unit.

[GCSE + IGCSE] Python Coursework Mini Project 2D arrays, File Reading and Writing and Sorting

**Teaching Duration: ** For main tasks, 3 lessons. This task can be expanded to challenge the top level students to add more and more features in. A further 1 to 2 lessons where we reverse engineer the flow charts which is very useful skill for the final exam Who is it for: Students studying GCSE in preparation for final project. Students studying IGCSE who are consolidating their skills at developing a large project. Also useful for staff struggling with teaching the course What’s included Instruction File: Includes detailed instructions and code that students should enter to complete the project Student File: partially completed code that students add to Teacher File: Completed project Text File: This project includes file reading, this is the text file to use. Make sure to save it in the same folder as the python file, or it will not work This covers every area of the programming side of the course from Units 1 and 2 completely. This is a perfect project for students to practice a larger project before tackling the coursework, or as a revision task for the practical exam / paper 2 by reverse engineering code/pseudocode and flow charts which is always a tricky area to learn. This has been in all exemplar papers, as well as the 2018 exam.

Activity is written using standard pseudocode/python, so easy to change and update for any other programming language . Use this to introduce arrays and records and discuss the diffrences between them both - with python coding in mind, as well as the exam based pseudocode being different from Python Questions from the new curriculum on 2D array data manipulation

Scratch [Modelling and Simulation]

My activity booklet for building a model of a the solar system in Scratch. Students complete some Internet research first (gives us a chance to look into searching techniques, fake news and logging data/information) We then spend a few lessons coding the solution to the model, getting the sun to rotate around the sun. Adding the moon to rotate around earth and then adding the other planets. This is a really fun activity that I use as a transition from talking about Internet safety, Internet skills to programing in Scratch, I have also included an example solution file, so you can learn how to code this particular solution, as well as demonstrate a working model the students.

Python Problem Solving Algorithm and Coding Challenges [GCSE + IGCSE]

A series of 11 coding challenges for students. This is a unit of work that I complete once my students have seen the basics of coding and have used the Mathematical Operators in Python (MOD % / DIVISION // INTEGER DIVISION) There are a variety of logical puzzles to work through and solve. I have included the solutions to all problems (11 Python files in ZIP format (TES doesn’t support direct upload of .py files)) For this unit, I had students work in groups. For my students who were struggling, I prepared some files with the pseudocode already typed in, or I hand drew some flow charts for some differentiation. For many of these, it would be very easy to build on and challenge your top level students to make some of the challenges even more difficult.

Scratch Programming Fractal Tree Activity

One of the areas of the national curriculum that we should be introducing students to is RECURSION. This is an excellent activity to introduce that concept in a visual way with a simple task to create a fractal tree in Scratch programming. This activity I had a learning observation on. I had my students work in small groups to try and complete the main activity together. When they finished this, they were to research other fractal activities on-line and see what they could create. Students really enjoyed this activity at the end of the Scratch topic to introduce a very complex topic that is not part of GCSE, but that appears again at IB level and A level. I expect students to learn that recursion is a complex rule that simplifies programs, but is very difficult to understand and it is a function that uses itself to solve a problem.

[GCSE + IGCSE] Introduction to Algorithms (Problem Solving)

This is the unit that I complete before I start programming with my GCSE students. It features a variety of problem solving activities that I use to introduce Flow Charts and Pseudocode. This has massively helped my students understand the concepts and process of planning before progressing onto writing code. This covers a lot of the concepts of Unit 1 and Unit 2 from the curriculum. Introduces the ideas of Abstraction, Decomposition, Algorithms etc

[GCSE+IGCSE] Computer Science PYTHON Arrays

Included: 10 project based activties. These address some standard algorithms (Search, Find Max and Min) and build into some menu building areas which uses Functions/Procedures. Solution files to all projects, including any advanced/challenge areas Links to video lessons for some projects End of Unit Project activity This is my very expansive unit of work on functions. This is the second last unit of work that I complete with my GCSE students, before we start the project (the final one being 2D arrays and records with File Reading/Writing, as well as some example projects) This is a very thorough set of activities which are all mini projects. Depending on the time you have, you could take each activity in turn and spend time designing, implementing and testing each of them. SOme of them I worked on and completed in pairs. There are 10 projects in total, each with a solution which has been fully tested. In some cases, to support my weaker students I spent some time making video lessons. These are hosted on youtube and are private and not accessible without the links in the documents - useful for professional development, for students who miss lessons or to support lower ability students (some of the areas covered are more advanced, so in fact my strongest students were also using them to advance their skills)

[GCSE+IGCSE] Strings, Functions and Procedures Unit

This is my Strings, Functions and Procedures unit that I use in the lead up to the end of Term 1 at Christmas. It compromises 9 individual tasks. Each of these tasks, I take at least two lessons to deliver with students. I start off each with some starter questions (included file) and a discussion of the task. At this point, I would expect my students to be comfortable with planning in pseudcocode and flow charts. For each activity, I either get them to design it for Scratch, or I create a partially completed plan which they then fill in the blanks (These are usually hand drawn, so I didn’t include them) We then code the solutions which normally takes a full lesson. To support and challenge students, several activities contain challenging scenarios to keep better students engaged allowing me to support weaker students to aim towards completing minimum requirements. After we completely implement them, we spend time discussing test plans, the purpose of testing etc. This covers a lot of the theory in the course of looking at modular testing, why we use predefined functions/procedures, how large groups of programmers work together to decompose a task and implement it simultaneously etc. For each of the 9 activities included, I have included blank student files (when they are required) tested solutions for each activity and the overview of the task with instructions. For this activity, it will require a bit of teacher input to explain task at the beginning. At this point, I show students the completed activity, so they know what they are aiming to produce. For my weaker students, I give them a copy of the completed code (eventually) and get them to add internal commentary, or do testing. In some cases, I make simple syntax errors in it and get them to fix it. This activity booklet takes me around 8-10 weeks off 3 lessons per week. We use the Christmas themed lessons at the end, this introduces/recovers arrays, as well as some challenging problem solving that we all work on in groups to complete.

[GCSE Computer Science] 2D Arrays Introduction [IGCSE also]

A series of activities to introduce students to 2D arrays. This is an area my students regularly struggled with understanding the concept. This year their test results were much improved compared to my last year groups - I believe this is mainly down to spending more time on getting students to visualise where data is, how it is stored and accessed. We spent a week on this activity - discussing the theory at the beginning of the lesson, tracing the execution, coding the solutions and then practicing writing flow charts for the equivalent pseudocode. I also updated this to work with records, but I will upload as a separate resource,

[GCSE+IGCSE] RECORDS ARRAYS FLOWCHARTS

A series of 6 activities (15 lessons following structure below) that can either be used to introduce Records, Arrays and Flow Charts, or as a revision tool at the end of introducing these. With each activity, I spend time going over the skills at the beginning of the lesson, with the students completing the flow chart in each scenario. For each activity, I have included extension activities to challenge the more advanced students. After each flow chart is completed, we review the learning at the end of the lesson. The second lesson for each, we review the learning from the previous activity and then code the solutions. I often do these in a mix of group and paired programming scenarios. This would also work well as a carousel activity, giving a set time at each station or, working in groups, students could implement the solutions for them and present their learning back to the rest of the class All in, covering theory, taking time to implement the code, and with testing at the end, this short set of activities takes us around 15 lessons and hugely benefited my students in the Paper 2 in the recent exam. There were a few questions which came up with regards to manipulating records / writing to files which, following these activities, my students were very confident with. This exercise was also used during a Looking For Learning classroom observation.

[GCSE + IGCSE] Computer Science Trace Tables, Algorithms and Efficiency

This is an excellent resource that I have created and used with my Y10 and Y11 GCSE class (Y10 are IGCSE, and is relevant to both courses) I use this as a collaborative carousel activity where students in pairs (or however you want to work it) look at two algorithms at a time, tracing the values of the variables. This is a problem solving activity that should hopefully challenge students Computational Thinking, as well as revising their skills with Trace Tables and predicting output of code, as well as spotting Logical errors. I have also used it to introduce the idea of preprocessing. This series of activities leads nicely into more challenging activities, such as sorting of data. When I teach this lesson, I use some theory resources and plenary activities, as well as some on-line quizzes over 3 lessons. Had a looking for learning observation whilst using these activities and feedback from observation was excellent. Having reviewed it with students, their feedback was (a long with the Data Structures activities uploaded and used prior to these activities) is that it really helped them to visualise how data is stored and manipulated in arrays, as well as introducing preprocessing (which appeared in this year exam) as well as revising trace tables. Allowing the students to work in collaboration, discussing with one another and doing some peer review tied in neatly with some of the observational areas which we are looking at with ATL and Life After Levels. I was also toying with doing this as a group presentation activity, where the students can ‘lead’ this activity and ‘Be the Teacher’ explaining the inefficiency of their algorithm and how the data can be as issue also. This was also a perfect opportunity to revise why we use arrays in the first place - as I got students to re-write the code without arrays and it was a crazy series of IF statements, so plenty of scope to draw in other areas of the course.

KS3 Computing - Cryptography Unit of Work - Lesson Presentations, Worksheets and Assessment

This is a whole unit of work that this aimed at KS3 - it covers all aspects of Cryptography that the students have absolutely loved doing and this has been uploaded to Google Classroom and made the whole unit very interactive. The work is split into Flight Paths and contains an assessment. All work has stretch and challenge extension tasks too. This is a really enjoyable unit of work for about 6 weeks.
