[GCSE] Computer Science Python FULL COURSE

[GCSE] Computer Science Python FULL COURSE

I have recently updated my coding activities. This is my introductory unit that I use in the first year of GCSE. It starts of with basics such as inputs and outputs, complex selection (IF) statements, building up to introductory arrays tasks. I have included links to the tutorial videos for the tasks which require them. I have included the student ‘starter’ files for some of the programs that require them I have included solution python files for the majority of tasks. The booklet has about 15 individual tasks. Several of these have extension tasks. Some of the individual tasks are actually a set of 10-15 challenging coding questions. This represents my full first year of introducing Python coding to GCSE level. I have other follow up activity booklets after this one that focus on STRING manipulation, FUNCTIONS, ARRAYS and 2D ARRAYS including FILE READING AND WRITING as well as some exemplar PROJECT PRACTICE tasks which I will be uploading shortly. I have uploaded the booklet in word format, so you can make changes if necessary and taken off the front cover. I have also included a PPT of starter questions which I use at the beginning of the lessons. I have uploaded separately some of the End of Topic quizzes which assess the understanding of this area. I have also included an activity in here which I use as an introduction to the GCSE coursework, but it is scaled down and appropriate to the material covered I haven’t included solutions for the challenges, or for the activities with the video support - if you think that you need these, please email me, but if you are following the scheme of work, they should be good problem solving practice.

AQA GCSE Computer Science Workbook (9-1)

AQA GCSE Computer Science Workbook (9-1)

A workbook covering the whole of the AQA GCSE Computer Science course. Each section has a combination of theory and questions. In class we use it to help students struture their notes and all students are provided with the workbook at the start of the year. Depending on your version of Word, occasionally the formatting may be slightly off-kilter with some information jumping between pages. So it is worth double checking before it goes to print - I learnt that the hard way!

Scratch Programming Y7/8/9 Activities Booklet

Scratch Programming Y7/8/9 Activities Booklet

Depending on the skills of your class, this is an activity book which can be used to introduce a lot of the Computing/Computer Science Curriculum in a creative way. 8 separate activities with links to completed/example projects and instruction videos. Lesson 1: Mad Libs This provides a nice opportunity to cross some Literacy boxes and cross curricular activities. It also ensures that students are being introduced to arrays and lists. This may seem complex at this point, but the activity really allows students to get the ideas behind it. One lesson to introduce and complete, scope for taking it further. We branched out for another lesson and students designed and implemented an excuse generator. Lesson 2: Digital Binary Perfect lesson to introduce Logical and Computational Thinking and go into as much or as little depth in Binary as you like. Again, this lesson took us about two lessons, as I made some follow up activities for the alarm clock and logic which are mentioned in the task themselves. Lesson 3: Randomly Random Introducing random functionality and variables to create a random character based on different sprites and costumes. We spent a few more lessons on this, as we advanced onto some follow up activities which are mentioned in the activities. Lesson 4: Keepy Uppy This is the first games based task that students make. It is based off the similar Atari game. All explained within file. I have also included the video lessons that I use to support my weaker students who are struggling in this. again, great scope to go above and beyond what is here, limited only by time and students abilities. Lesson 5: Harry Potter Challenge I complete this activity in pairs for a change on some of the other tasks. Students work together taking turns to be coder and tester, swapping often. They really love this and we spent a while designing other parts for our game and having a class competition on them Lesson 6: Group Project Another group based learning activity. Swapping groups (not necessary) we look at some of the pseudocode and flowcharts (included for several tasks here) I have included some links to some excellent exemplar student work here. Again, introducing simulation to students and with scope to go beyond what is included in the activities. Lesson 7: Practical Assessment As part of moving to life beyond levels (I have left levelling info in this, but included the word file and you are welcome to edit) This I do over one lesson - students struggle to finish it, so it really does differentiated the different skill levels Bonus Activity: Recursion I have included a Fractal Tree Activity that I use to teach about recursion. Fun end of term challenge.
