What do teachers have to say about this resource? (5249)
"A wonderful resource that supplements my own teaching resources/strategies. These resources help supplement existing resources and stretch my students understanding and knowledge... It saves much time planning and I can focus more on teaching. The resources match well to my scheme of work and lesson plans... Solutions to the activities [are also provided] which is a great help." - T Ditta, HoD, customer
"It's great for homework as well as classwork... Supports learning as well as checking knowledge... Matches [the OCR specification] well." - J Fuller, HoD, customer
"Good, well structured and the questions and answers are clear to understand and follow... I liked the fact that the resource tackles the more technical aspects of the course rather than just presenting theory... The educational value of this resource is its ability to reinforce learning outside of the classroom and as a revision resource... the resource matches the specification well and is useful for revision and starter type activities as well as for homework's." - S Barron, Head of ICT, Independent Reviewer
"Fantastic layout with clear thought into separating each section, so it is clear for the teacher to orientate students to each part and also clear for the students to use. I like the AfL element where the scoring at the front, against the maximum mark... Meets the requirements of OCR very well, with links to specification clear... [There is a] a good onus on independent learning, which is important for students. They need to be guided, not told and this supports that." - L Price, HoD, independent reviewer
"Lovely resource - I like the writing style, very well suited to all levels with a GCSE Computing class... These will make excellent homeworks and I'm pleased that the answers have been included as this makes life so much easier... Matches the [OCR] specification very well... The interpretation of the level of detail needed is good." - C Charles, Computing teacher, independent reviewer
