Are you looking for a robust, ready to use summative assessment to test your students understanding of data representation? Computers science teachers have been left in a wilderness, without a rigorous, fair and consistent way to test your student’s knowledge in key stage 3 … UNTIL NOW! WHAT IS TESTED? This written test has been carefully mapped to the UK’s Computing At Schools (CAS) Progression Pathways. It includes a mixture of multiple-choice, short answer and long answer questions. This assessment covers the following CAS Progression Pathway descriptions: Performs more complex searches for information e.g. using Boolean and relational operators. Analyses and evaluates data and information and recognises that poor quality data leads to unreliable results, and inaccurate conclusions. Knows that digital computers use binary to represent all data. Understands how bit patterns represent numbers and images. Knows that computers transfer data in binary. Understands the relationship between binary and file size (uncompressed) Defines data types: real numbers and Boolean. Queries data on one table using a typical query language. Understands how numbers, images, sounds and character sets use the same bit patterns. Performs simple operations using bit patterns e.g. binary addition. Understands the relationship between resolution and colour depth, including the effect on file size. Distinguishes between data used in a simple program (a variable) and the storage structure for that data. . The test lasts 50 minutes. WHO IS THIS ASSESSMENT FOR? This test is paper 1 and has been written for year 7. HOW DO I USE THE ASSESSMENT? This assessment is super easy to use. Simply print out the question paper and give to your students. It is better to run this assessment in class rather than as a homework task to ensure reliability. Students complete the test on paper. HOW IS THE ASSESSMENT MARKED? You mark the papers yourself but don’t worry, you get an easy to follow mark scheme and can even watch the helpful video which shows you exactly how to mark it. HOW IS THE ASSESSMENT GRADED? Included in the resource is an Excel spreadsheet. Once you enter the marks onto the spreadsheet, it will automatically show you the total marks, the grade (A* to U) and if they have met expectations, are above expectations or are below expectations to help you with report writing. You also get a summary showing you how well the CAS Progression Pathways have been answered by your students to help you with future planning.

This has got to be one of the most unusual and fun ways of introducing your students to the delights of the bubble, insert and merge sorting algorithms. Even if your exam board only teaches two of these sorting algorithms it’s still worth getting this activity and teaching all three as it is just so much fun! Using an escape room activity that involves a witch and a goblin (who doesn’t want that?) your students will learn the basics of how these three algorithms work. This is a student-led interactive escape room activity that is ideal for social distancing and does not require any student computers and they can remain at their individual desks and yet they will still be working together. The entire activity will last a single lesson. Your role is to not do a lot and put the emphasis on your students working together. Early on you will be turned into a goblin! Sorry (not really sorry) so you may want to practise your goblin roar for when it’s called upon. Students therefore cannot rely on you to help them (because you’ll be a goblin) and they’ll have to work together (either as a whole class or in smaller teams if you prefer) to try and solve all the riddles in their “spell books” for themselves. The main activity is introduced via a whole-class PowerPoint presentation which includes videos giving the students vital instructions and helping them if necessary. Each pupil is given a printout of the spell book which contains all the challenges. This escape room style activity gives your students a great introduction to the three sorting algorithms (bubble sort, insert sort and merge sort) and will certainly give your students a boost at the start of learning this topic. Suitable for higher KS3 classes and GCSE Computer Science classes.
