Unit A452: Practical investigation Controlled assessment: 30% of the total GCSE - 45 marks The marks are broken down as follows: Practical activity - 15 marks Effectiveness and efficiency - 10 marks Technical Understanding - 10 marks Testing, evaluation and conclusions - 10 marks Duration: Approx 20 hours A practical investigative task where OCR sets a scenario with a choice of research tasks. This unit is designed to provide students with an opportunity to carry out a practical investigation into a computing issue and engage with computing in the real world. Students should study one from a range of topics which will be supplied by OCR. Students will be expected to carry out practical investigations of the topic(s) and any supplementary research necessary to complete these investigations. Assessment is based on a report in which the topic is analysed, justified and evaluated showing evidence of the practical work undertaken. For Unit A452 students will need to deal with new concepts and these will be introduced as a class activity before starting the controlled assessment task. Following this preparation, students will be introduced to the task through teacher led activity, then group activity and finally individual work on the task. This controlled assessment is to be taken under Medium Control meaning students must complete all work, with the exception of research, under informal supervision. Informal supervision means that the teacher must be able to authenticate the work as the students’ own unaided work. A candidate can re-take a controlled assessment but any work that has been previously assessed cannot be returned to the candidate and, along with moderated work returned to centres, should be destroyed. Candidates may re-use any controlled assessment group research work but must completely redo the individual activity part of the assessment.

A practical investigative task where OCR sets a scenario with a choice of research tasks.

This unit is designed to provide students with an opportunity to carry out a practical investigation into a computing issue and engage with computing in the real world.
Students should study one from a range of topics which will be supplied by OCR. Students will be expected to carry out practical investigations of the topic(s) and any supplementary research
necessary to complete these investigations.
Assessment is based on a report in which the topic is analysed, justified and evaluated showing evidence of the practical work undertaken.

For Unit A452 students will need to deal with new concepts and these will be introduced as a class activity before starting the controlled assessment task.

Following this preparation, students will be introduced to the task through teacher led activity, then group activity and finally individual work on the task.

This controlled assessment is to be taken under Medium Control meaning students must complete all work, with the exception of research, under informal supervision. Informal supervision means that the teacher must be able to authenticate the work as the students’ own unaided work.

A candidate can re-take a controlled assessment but any work that has been previously assessed cannot be returned to the candidate and, along with moderated work returned to centres, should be destroyed. Candidates may re-use any controlled assessment group research work but must completely redo the individual activity part of the assessment.
