1.2 About the Entry Level Certi� cate in Science speci� cation

This booklet contains OCR’s Entry Level Certi� cate in Science speci� cation for teaching from September 2011 and for � rst certi� cation in June 2013.

This speci� cation has been speci� cally designed to meet the need of those candidates in Key Stage 4 for whom courses leading to a GCSE examination do not represent a realistic or appropriate goal.

Since it does not lead to a GCSE quali� cation, there is no requirement for this speci� cation to conform either to the general GCSE criteria or to the science-speci� c criteria for GCSE. It does, however, meet the requirements of the Ofqual common criteria and criteria for Entry Level quali� cations and covers those aspects of the Science National Curriculum Programme of Study for Key Stage 4 appropriate for students working at this level. The course will lead to � nal certi� cation by OCR at Entry Level 1, 2 or 3. It is possible for interim certi� cation to be achieved by candidates at stages during the course. These interim certi� cates can be awarded by the centre at Bronze, Silver and Gold levels.

The speci� cation can be used as the basis of an independent course for those candidates identi� ed as unlikely to be entered for GCSE, and as a source of material to support the teaching of lower-attaining candidates in teaching groups where the majority will be entered for the Foundation Tier of a GCSE examination.

The speci� cation consists of 39 items, equally divided between biology, chemistry and physics. Candidates do not need to have been assessed for all items in order to enter for certi� cation. There is no minimum number of items required but an approximate balance between Biology, Chemistry and Physics is expected.

The absence of the requirement to conform to GCSE criteria enables a signi� cantly more � exible approach to be used and this is re� ected in an increased emphasis on positive achievement through the realisation of short-term goals, using 100% teacher assessment.

There is no terminal examination, and assessment is by means of a combination of short end-of-item tests, can-do tasks and a practical task. All assessments are centre-based, are supervised by the candidate’s own teacher, and are carried out at times determined by the centre. All assessments will be subject to normal moderation procedures by OCR.

Part of the inherent � exibility of the Entry Level Science speci� cation is the linking of the mark descriptors for the practical task to those for the controlled assessment tasks for OCR Twenty First Century GCSE Science and OCR Gateway GCSE Science. This allows the possibility of progression from Entry Level Science to GCSE Science. Candidates making this progression can be entered, as late as February of Year 11, for the Foundation Tier of an OCR GCSE Science quali� cation.

The speci� cation is approved by Ofqual as a national Entry Level award and is also approved by DCELLS for use in maintained schools in Wales and, by CCEA, in Northern Ireland.

1.3 Guided learning hours

There are no speci� ed guided learning hours for this course but typically the course could take between 60 and 120 guided learning hours depending on the ability of the candidates and the delivery approach adopted.

2.2 Layout of Item content

The speci� cation content is displayed as 39 items. For each item the cells in the left-hand column list suggested activities which teachers could use in developing the content.

Each of the cells in the right-hand column lists the content statements which are open to assessment in the end-of-item tests. In the end-of-item tests, candidates will be expected to be able to apply their knowledge and understanding in straightforward contexts.

The use of ICT is integral to the study of science and every opportunity should be taken to use ICT as part of the learning process, e.g. using digital photography to record variation in animals and plants in item B3 Extinction.

How Science Works

In addition to the scienti� c knowledge, understanding and skills that are detailed in the items which follow, candidates require an understanding of the fundamental scienti� c processes that underpin these explanations. Studying these processes will provide candidates with some understanding of:

• how scienti� c explanations have been developed

• their limitations, and

• how they may impact on individuals and society.

Assessment of Entry Level Certi� cate in Science 3

3.1 Overview of the assessment in Entry Level Certi� cate in Science

There is one unit made up of three assessment elements and the credit for each element is aggregated by the centre to produce a � nal points total for each candidate.

Entry Level Science (R591)

Element 1: End-of-Item Tests

70% of the total 70 points

• Candidates may submit the results of a maximum of 35 out of 39 tests. This number should consist of a minimum of nine items from each of Biology, Chemistry and Physics to provide an appropriate overall balance.

• All tests carry 15 marks and are approximately 10 minutes in duration.

• The marks for each test are converted into points. Each test yields a maximum of two points.

Element 2: Can-Do Tasks

10% of the total 10 points

• Each task is marked out of 1 mark, 2 marks or 3 marks. A maximum of 10 assessed tasks can be used for the � nal points total giving a maximum of 30 marks. This mark is divided by 3 to give a maximum of 10 points.

• Assessed in practical situations.

Element 3: Practical Tasks

20% of the total20 points

• Centres are able to devise their own practical tasks or may use ones suggested in the teacher support handbook

• Candidates can attempt more than one of these tasks but the points submitted must be based on each candidate’s response to the whole of one task.

• The task is assessed by the teacher using performance descriptors for � ve aspects, awarding marks out of 4 for each.

• The total mark, out of a maximum of 20, is directly converted into points. Suggested time: 4 hours.

Postal moderation of a sample of candidates’ work takes place at the end of the course. Marked end-of-item tests and evidence from all other elements must be retained for all candidates in case it is required for moderation.

50 © OCR 2011 Entry Level Certi� cate in Science

3

3.2 Assessment availability

There is one assessment series each year in June.

The � rst series that candidates may be awarded this quali� cation is June 2013.

3.3 Assessment objectives

Candidates are expected to demonstrate their ability to:

AO1 Recall, select and communicate their knowledge and understanding of science;

AO2 Apply skills, knowledge and understanding of science in practical and other contexts;

AO3 Collect, present and recognise patterns in data, draw conclusions and comment on methods used to collect data.

3.4 Assessment objective weightings

The relationship between the elements of assessment and the assessment objectives is shown in the following grid:

Element of assessment % of Entry Level Science

AO1 AO2 AO3 Total

End-of-Item Tests 37 28 5 70

Can-Do Tasks – 10 – 10

Practical Task 2 2 16 20

Total 39 40 21 100

3.5 Awarding of grades

The grades awarded for the Entry Level Certi� cate will be at three levels: Entry 1, Entry 2 and Entry 3.

All mark schemes have been written to address the following targeted thresholds:

Speci� cation Grade Entry 3 Entry 2 Entry 1

Target 80% 60% 40%

51 © OCR 2011 Entry Level Certi� cate in Science

Internal Assessment 4

4.1 Nature of assessment

• Teachers record the raw marks generated from their candidates’ work for the three elements of assessment (end-of-item tests, can-do tasks and the practical task).

• These raw marks are converted into points for each element (using separate conversion scales in order to preserve the overall weightings of the assessment).

• The aggregation of these points leads to the award of Bronze, Silver and Gold interim certi� cates by the centre. Following � nal entry, OCR will certi� cate a candidate’s overall level of achievement at Entry Level 1, 2 or 3 following moderation.

Principles of assessment

Introduction to skills assessment

End-of-Item Tests (70%)

An end-of-item test is an integral part of each of the 39 items forming the speci� cation. It is accepted that absence through illness, or other unforeseen circumstances, may affect candidates’ assessment and they are therefore expected to submit the results for a maximum of 35 of these tests. (When candidates are able to take more than 35, the results of the best 35 tests may be submitted for certi� cation.) There is no minimum requirement.

The tests are supervised by teachers in normal lesson time and will be taken at times convenient to the centre. Teachers are required to ensure that normal examination conditions for supervision and invigilation are maintained. Candidates who miss a test may take it on another occasion convenient to the centre. Further details are available in the teacher support handbook for centres.

For each item, candidates are only allowed one attempt at the associated end-of-item test. Candidates are not allowed to retake any end-of-item tests or take an alternative version of any end-of-item test.

All tests carry 15 marks and are constructed to a common format. The breakdown of marks will be:

Assessment Objectives Marks

AO1 Recall, select and communicate their knowledge and understanding of science. 8 ± 2

AO2 Apply skills, knowledge and understanding of science in practical and other contexts. 6 ± 2

AO3 Collect, present and recognise patterns in data, draw conclusions and comment on methods used to collect data. 1 ± 1

52 © OCR 2011 Entry Level Certi� cate in Science

4

There is no formal time limit for these tests, but it is expected that most candidates will be able to complete a test within 10 minutes.

Marking of the tests will be carried out by teachers according to the detailed mark schemes provided by OCR. All test papers and mark schemes should be retained securely until the end of the course and will be sampled during the moderation process.

The raw marks obtained from these tests are converted into points according to the following scale:

Raw Mark 2–4 5–7 8–11 12–15

Points 0.5 1 1.5 2

The maximum points total for this element of the assessment is 70 (= 35 tests × 2).

Can-Do Tasks (10%)

These tasks are designed to provide, at frequent intervals, positive reinforcement of candidates’ attainment and generate an assessment of the practical application of their knowledge, understanding and skills.

The tasks enable all candidates to achieve success but still provide challenge and reward for high attaining candidates. The tasks are set at three levels.

Basic Skills: 1 Mark Tasks Simple practical skills, which should be within the reach of all candidates.

Intermediate Skills: 2 Mark Tasks More complex tasks which require more than one practical skill.

Advanced Skills: 3 Mark Tasks Extended activities which require a candidate to perform a sequence of more demanding operations.

Opportunities to demonstrate pro� ciency in can-do tasks are indicated throughout the speci� cation content and are summarised in Appendix B. Frequent opportunities will arise during the course for candidates to attempt these tasks.

It is expected that during their course candidates will attempt a wide range of tasks at a variety of levels and that all candidates will be able to achieve success at their level. A total of 36 tasks is available and candidates may gain credit from a maximum of 10 of them. Thus, candidates can gain a maximum of 10 marks from ten basic skills tasks or 20 marks by matching 10 intermediate skills tasks or 30 marks by successfully completing 10 advanced skills tasks. However, any combination of basic, intermediate and advanced tasks may be taken.

There is no formal time for these can-do tasks. It is expected that candidates are assessed by their teachers in their practical lessons.

53 © OCR 2011 Entry Level Certi� cate in Science

Practical Task (20%)

Candidates are assessed on their ability to:

• plan a suitable safe procedure

• display data in a suitable format

• recognise patterns in data

• interpret data and relate to relevant science

• comment on the method used to collect data.

The performance descriptors for the practical task are provided in Appendix C.

Since the collection of data is not assessed in the practical task it is not essential for candidates to collect all of the data which is to be used in the task. Their own primary data may be supplemented with extra data from other candidates or classes, demonstrations or other sources.

The practical task is expected to take approximately four to � ve hours.

4

Links with GCSE

It is recognised that many candidates, initially of low attainment at the start of the Entry Level course, will make suf� cient progress to warrant an entry to GCSE Science.

The practical task is a useful preparation for undertaking a GCSE Controlled Assessment task. The task and the performance descriptors have been developed to allow an easy progression from the requirements for Entry Level to those for GCSE Science in the Gateway or Twenty First Century suites.

4.2 Supervision and authentication of internally assessed work

OCR expects teachers to supervise and guide candidates who are undertaking work that is internally assessed. The degree of teacher guidance will vary according to the kind of work being undertaken. It should be remembered, however, that candidates are required to reach their own judgments and conclusions.

When supervising internally assessed tasks, teachers are expected to:

• offer candidates advice about how best to approach such tasks

• exercise supervision of the work in order to monitor progress and to prevent plagiarism

• ensure that the work is completed in accordance with the speci� cation requirements and can be assessed in accordance with the speci� ed mark descriptions and procedures.

The centre must ensure that suf� cient work takes place under direct supervision to allow the teachers concerned to authenticate each candidate’s work with con� dence.

54 © OCR 2011 Entry Level Certi� cate in Science

4

4.3 Production and presentation of internally assessed work

Candidates must observe certain procedures in the production of internally assessed work:

• any copied material must be suitably acknowledged

• where work is based on the use of secondary data, the original sources must be clearly identi� ed

• each candidate’s work for the assessed practical task should be stapled together at the top left-hand corner and have a completed cover sheet as the � rst page.

4.4 Annotation of candidates’ work

Each piece of assessed work should show how the marks have been awarded in relation to the performance descriptors.

The writing of comments on candidates’ work provides a means of dialogue and feedback between teacher and candidate and a means of communication between teachers during internal standardisation of coursework.

The use of a completed cover sheet, available for each candidate’s practical task, provides a means of communication between teacher and moderator and might replace the need for annotation.

4.5 Marking internally assessed work

A detailed mark scheme is provided with each end-of-item test. It is essential that all teachers mark the tests consistently and accurately according to the guidance provided.

All marking must be done in red ink/biro and acceptable answers need to be indicated using a tick (�). All answers which are wrong or are too vague should have a cross (�) against them.

Omissions should be indicated by the use of the � sign. All responses given by the candidate must show clearly that the teacher has considered the answer given.

It is not necessary to total the mark for each question.

In rare cases a candidate may give an answer which is not provided on the mark scheme. If the teacher considers that the answer is worth the mark, then it should be awarded. In such cases the test paper should be annotated and the notice of the moderator be drawn to it when the sample for moderation is despatched during the � nal certi� cation process.

The raw marks obtained from these tests are converted into points according to the following scale:

Raw Mark 2–4 5–7 8–11 12–15

Points 0.5 1 1.5 2

Element 1: End-of-Item Tests (Points total out of 70)

The marks and points are then entered on each candidate’s record card.

The total number of marks required for certi� cation is 35. The maximum points total for this element of the assessment is 70 (= 35 tests x 2). Further tests may be sat to achieve this; however candidates may only sit end-of-item tests once.

55 © OCR 2011 Entry Level Certi� cate in Science

4

When a task has been successfully completed, the number of marks allocated to the task (1, 2 or 3, depending on the level of the task) are awarded and recorded on candidates’ record cards. No credit is available for partial completion, so that a 3 mark task can only have 3 or 0 marks awarded; it is not possible to award 1 or 2 marks for a 3 mark task.

A successfully completed task is where the candidate, working independently without signi� cant teacher intervention or assistance, has:

• collected appropriate materials and equipment to perform the task

• worked safely, maintaining an organised working environment

• produced evidence to show that the outcome identi� ed by the task has been achieved.

At the end of the course, results for the highest scoring ten tasks should be identi� ed and the total mark calculated out of a maximum of 30. This is then divided by three to give a � nal points total out of 10, which should be entered on each candidate’s record card.

Candidates can attempt any number of can-do tasks.

Element 2: Can-Do Tasks (Points total out of 10)

Marks are awarded for each of � ve aspects of the task (see Appendix C). Each aspect carries a maximum of four marks. The award of marks is based on the professional judgement of the science teacher, working within a framework of descriptions of performance (see Appendix C). Different aspects of performance are identi� ed in the marking grid. For each of these, two descriptions of performance (for 1–2 and 3–4 marks) identify what is expected for candidates working at different levels.

The task should be marked using a ‘best � t’ approach. For each of the aspects, teachers should � rst use their professional judgement to select one of the two band descriptors provided in the marking grid that most closely describes the quality of the work being marked.

To select the most appropriate mark within the band descriptor, teachers should use the following guidance:

• where the candidate’s work convincingly meets the statement, the higher mark should be awarded

• where the candidate’s work just meets the statement, the lower mark should be awarded.

Marking should be positive, rewarding achievement rather than penalising failure or omissions. The award of marks must be directly related to the marking criteria.

Teachers should use the full range of marks available to them and award full marks in any band for work which fully meets that descriptor. This is work which is ‘the best one could expect from candidates working at that level’.

Marking decisions should be recorded on a candidate cover sheet. This cover sheet can be downloaded from the OCR website www.ocr.org.uk. For any aspect, a tick on the grid should be used to indicate the performance statement that best matches the work. When each aspect of performance has been assessed in this way, the addition gives a total in the range of 0–20 points.

Each candidate’s total mark for the practical task must come from a single task.

The maximum total mark is 20 and this is converted directly into points which should be entered on each candidate’s record card.

Element 3: Practical Task (Points total out of 20)

56 © OCR 2011 Entry Level Certi� cate in Science

4

Teachers are required to record each candidate’s achievement on a candidate record card.

The candidate record card is a four-sided document. Page 1 has spaces to indicate the total points accumulated at the time the course is completed. Pages 2, 3 and 4 deal with the can-do tasks, the practical task and the end-of-item test results.

The candidate record card also forms a useful ‘wrap-round’ cover for the portfolio of assessed work from the candidate.

All assessed work which has contributed to the � nal total for each candidate must be available for moderation.

For each candidate selected at the time of moderation, the moderator is sent a copy of the candidate record card.

The totals of the three elements are added to establish each candidate’s � nal points total and this should be submitted to OCR on form MS1 or by Interchange, by the published deadline in the year of entry for Entry Level certi� cation. These forms are produced and despatched at the relevant time based on entry information provided by the centre.

Recording and Submitting Marks

4.6 Moderation

All internally assessed work is marked by the teacher and internally standardised by the centre. Points totals are then submitted to OCR, after which moderation takes place in accordance with OCR procedures. The purpose of moderation is to ensure that the standard of the award of marks/points for work is the same for each centre and that each teacher has applied the standards appropriately across the range of candidates within the centre.

All centres entering candidates are subject to quality control via moderation of a sample of candidates’ work towards the end of the course. This speci� cation offers the opportunity for moderation evidence to be submitted electronically via the OCR Repository (see Entry codes in Section 7.1 Registration and entries of this speci� cation).

OCR will select the sample and inform the centre where the sample of work is to be sent. Materials must be despatched to arrive with the moderator within 5 days of receipt of the sample request. Any delays may affect the issue of candidates’ results. In the case of centres using the OCR Repository, moderators will access coursework directly:

• if there are 10 or fewer candidates the complete work of all candidates should be sent to the moderator (or be uploaded to the OCR Repository) without the need to wait for a request from OCR

• any correspondence with OCR relating to Special Arrangements and the work of the appropriate candidates should be sent to the moderator (or be uploaded to the OCR Repository) with the sample

• completed form CCS160 should accompany the work (or be uploaded to the administration section of the OCR Repository) – candidate authentication forms should be retained by the centre

• centres are advised to have the work of all candidates available in case a further sample is required by the moderator

• postal moderation only – it is advisable to remove the covers of coursework where they might add unnecessary bulk to the parcel and increase the cost of its despatch

• centres should use a system that provides for tracking should the parcel delivery be delayed

• cover sheets must be attached to each candidate’s practical task work (or be uploaded to the OCR Repository).

Any subsequent requests from the moderator e.g. to reconsider the centre’s order of merit or to supply further samples of work should be acted upon with the minimum of delay.

The outcome of moderation will be noti� ed to the centre in due course, at which stage the centre will have the right to submit a result enquiry, requesting a re-moderation.

After moderation has been completed, all candidates’ work must be kept securely in the centre until the results have been published and until any results enquiries/appeals have been concluded.

58 © OCR 2011 Entry Level Certi� cate in Science

4

4.7 Minimum requirements for internally assessed work

If a candidate submits no work for this internally assessed unit, then the candidate should be indicated as being absent from that unit on the mark sheets submitted to OCR. If a candidate completes any work at all for this internally assessed unit, then the work should be assessed according to the criteria or mark scheme and the appropriate mark awarded, which may be zero.

4.8 Submitting the moderation samples via the OCR Repository

The OCR Repository, which is accessed via Interchange, is a system which has been created to enable centres to submit candidate work electronically for moderation. It allows centres to upload work for several candidates at once but does not function as an e-portfolio for candidates.

The OCR Entry Level Certi� cate in Science Unit R591 can be submitted via the OCR Repository.

Once you receive your sample request, you should upload the work to the OCR Repository within three days of receiving the request. Instructions for how to upload � les to OCR using the OCR Repository can be found on the OCR website.

It is the centre’s responsibility to ensure that any work submitted to OCR electronically is virus-free.

59 © OCR 2011 Entry Level Certi� cate in Science

4

4.9 Linking of points to interim awards

The centre may award interim certi� cates at Bronze, Silver and Gold, as described below. These interim awards provide motivation and maintain engagement by recognising candidates’ progress.

Awards are based on credit accumulation. Any combination of points gained from the assessment elements is used to reach the threshold total for each level of interim award.

Teachers will need to monitor the performance of the candidates at frequent intervals during the course. As they approach the three key points for the interim awards of Bronze, Silver and Gold the candidates should be aware of how close they are to achieving their award.

Bronze Award (40%)

An example of a performance for Bronze award would be:

End-of-Item Tests – 30 points out of 70

Can-Do Tasks – 5 points out of 10

Practical Task – 5 points out of 20

This represents an overall achievement of 40%.

Silver Award (60%)

An example of a performance for Silver award would be:

End-of-Item Tests – 43 points out of 70

Can-Do Tasks – 7 points out of 10

Practical Task – 10 points out of 20

This represents an overall achievement of 60%.

Gold Award (80%)

An example of a performance for Gold award would be:

End-of-Item Tests – 55 points out of 70

Can-Do Tasks – 9 points out of 10

Practical Task – 16 points out of 20

This represents an overall achievement of 80%.

Access arrangements for Entry Level Certi� cate in Science

Arrangements for candidates with special needs for Entry Level Certi� cate speci� cations are based on the principle that the centre is best able to assess the needs of the candidate and the appropriateness of the arrangement required. Arrangements for candidates with special needs should not advantage nor disadvantage a particular candidate, nor should they reduce the reliability and validity of the assessment.

The arrangements for candidates with special needs are more � exible than those currently available at GCSE and as such it should not be assumed that any arrangements made at Entry Level Certi� cate Level will automatically be available at GCSE or GCE Level. Please consult the JCQ bookle t Access Arrangements, Reasonable Adjustments and Special Consideration, chapter 8. Entry Level Forms are available on the JCQ website (Forms 11–13).

The following arrangements can be made for candidates without permission being sought:

• mechanical and technological aids may be used by candidates who are physically dependent on them; (screen readers must not be used in reading texts)

• instructions regarding the conduct of any In-Course tests may be simpli� ed

• language support staff may provide linguistic help; (please see regulations relating to readers and scribes, sign language and oral language modi� ers)

• bilingual and word exchange lists may be used.

For information relating to permission to use the following special arrangements, please consult the JCQ booklet Access Arrangements, Reasonable Adjustments and Special Consideration, chapter 9.

Under certain circumstances:

• the teacher may act under the candidate’s instructions to perform simple physical actions which the candidate is unable to undertake; (please see regulations on the use of practical assistants)

• mechanical and technological aids may be used by candidates who generally use them in their normal work; (for screen readers, please see regulations relating to readers)

• communicators or signers may be used

• readers and amanuenses may be used

• the tests may be modi� ed as necessary for visually impaired candidates. It is the responsibility of the centre to Braille or enlarge the tests.

It is expected that, generally, the candidate’s own teacher will act as a communicator, a signer, a reader or an amanuensis.

Further clari� cation of any special arrangements may be obtained by consulting the JCQ booklet Access Arrangements, Reasonable Adjustments and Special Consideration or by contacting OCR Special Requirements Team.

Administration of Entry Level Certi� cate in Science

Centres must be registered with OCR in order to make any entries, including estimated entries. It is recommended that centres apply to OCR to become a registered centre well in advance of making their � rst entries.

Both estimated and � nal entries must be made in the certi� cation year. Estimated entries, giving estimated numbers only, are needed for the appointment of the centre moderators and � nal entries provide the necessary individual candidate details.

Candidates should be entered for the quali� cation code R591.

It is essential that entry codes are quoted in all correspondence with OCR.

For this quali� cation candidates must be entered for either component 01 (electronic submission via the OCR Repository) or 02 (postal moderation). Centres must enter all of their candidates for ONE of these components. It is not possible for centres to offer both components within the same series.

7.1 Registration and entries

7

Entry option code Component code Submission method

R591A 01 OCR Repository

R591B 02 Postal moderation

Candidate entries must be made by the dates published on the OCR website.

7.2 Entry deadlines

Interim certi� cates for Bronze, Silver and Gold awards can be awarded by centres at any time during the course, but � nal certi� cates will be issued by OCR when the candidates have completed the course.

Final certi� cation is available from OCR on a three-point scale of grades: Entry 1, Entry 2 and Entry 3, where Entry 3 is the highest grade available.

7.3 Grading and award of certi� cates

Candidates may re-sit the quali� cation an unlimited number of times.

7.4 Quali� cation re-sits

Under certain circumstances, a centre may wish to query the result issued to one or more candidates. Enquiries about results must be made immediately following the series in which the relevant unit was taken (by the enquiries about results deadline).

Please refer to the JCQ Post-Results Services booklet and the OCR Admin Guide for further guidance about action on the release of results. Copies of the latest versions of these documents can be obtained from the OCR website.

7.5 Enquiries about results

Appendix A: Grade descriptionsA

Grade descriptions are provided to give an indication of the standards of achievement likely to have been shown by candidates awarded particular grades. The descriptions should be interpreted in relation to the content speci� ed in the speci� cation: they are not designed to de� ne the content. The grade awarded will depend in practice upon the extent to which the candidate has met the assessment objectives overall. Shortcomings in some aspects of the assessment may be balanced by better performance in others.

Knowledge and Understanding of Science

Candidates recall, understand and apply knowledge from a limited range of the de� ned speci� cation content. For example: they are able to label a diagram of a plant to show roots, stems, leaves, � owers and buds; they know that gold and silver are expensive, shiny and heavy; they know that forces can be pulls, pushes, twists or bends. They are able to communicate simple ideas using everyday language.

Can-Do Tasks

Candidates show that they are able to carry out some simple tasks, some of which involve the use of scienti� c equipment, safely. For example: ‘I can match an animal to where it lives or when it lived’; ‘I can separate a simple mixture’; ‘I can write a message in mirror’.

Practical Task

Candidates can carry out simple investigative work with help. They can work safely to collect at least one piece of evidence. They can state simply what they have found out, can comment on the procedures used or the evidence obtained.

Knowledge and Understanding of Science

Candidates recall, understand and apply knowledge from a range of the de� ned speci� cation content. For example: they know that animals get their food from eating plants and other animals; know that a mixture contains two or more non-combined substances and know about using mobile phones safely. They communicate ideas making limited use of scienti� c and technical vocabulary.

Can-Do Tasks

Candidates show that they are able to carry out simple tasks, some of which involve the manipulation of scienti� c equipment safely. For example: ‘I can use Universal Indicator solution to � nd pH’; ‘I can carry out a test to show the presence of carbon dioxide’; ‘I can use a newtonmeter to measure force’.

Practical Task

Candidates carry out some investigative work in which they research and collect some evidence. They can process, in simple terms, the data that has been collected and make a relevant comment about the procedures used or the evidence obtained.

A

Knowledge and Understanding of Science

Candidates recall, understand and apply knowledge from a wide range of the de� ned speci� cation content. For example: understand that different people have different lifestyles and therefore dietary requirements; know the physical differences between metals and non-metals; know that unbalanced forces make things move. Candidates obtain information from simple tables and charts and are able to link cause and effect in simple contexts. They communicate ideas well making some use of scienti� c and technical vocabulary.

Can-Do Tasks

Candidates show that they are able to carry out simple tasks, including those which involve the manipulation of scienti� c equipment, safely and with con� dence. These may require candidates to take accurate measurements. For example: ‘I can use a thermometer to measure temperature accurately’; ‘I can do a test to compare quantities of Vitamin C in fruit juice’.

Practical Task

Candidates carry out work in which they plan, research, collect and record evidence, and present data in the form of simple tables or charts. They identify a straightforward trend or pattern in their results and make summarising comments on the procedures used and the evidence obtained. In a simple way they relate their investigative work to appropriate scienti� c knowledge and understanding.

Appendix E: Guidance for the production of electronic internal assessment

E

Structure for evidence

An internal assessment portfolio is a collection of folders and � les containing the candidate’s evidence. Folders should be organised in a structured way so that the evidence can be accessed easily by a teacher or moderator. This structure is commonly known as a folder tree. It would be helpful if the location of particular evidence is made clear by naming each � le and folder appropriately and by use of an index called ‘Home Page’.

There should be a top level folder detailing the candidate’s centre number, candidate number, surname and forename, together with the unit code R591, so that the portfolio is clearly identi� ed as the work of one candidate.

Each candidate produces an assignment for internal assessment. The evidence should be contained within a separate folder within the portfolio. This folder may contain separate � les.

Each candidate’s internal assessment portfolio should be stored in a secure area on the centre’s network. Prior to submitting the internal assessment portfolio to OCR, the centre should add a folder to the folder tree containing internal assessment and summary forms.

Data formats for evidence

In order to minimise software and hardware compatibility issues it will be necessary to save candidates’ work using an appropriate � le format.

Candidates must use formats appropriate to the evidence that they are providing and appropriate to viewing for assessment and moderation. Open � le formats or proprietary formats for which a downloadable reader or player is available are acceptable. Where this is not available, the � le format is not acceptable.

Electronic internal assessment is designed to give candidates an opportunity to demonstrate what they know, understand and can do using current technology. Candidates do not gain marks for using more sophisticated formats or for using a range of formats. A candidate who chooses to use only word documents will not be disadvantaged by that choice.

Evidence submitted is likely to be in the form of word processed documents, PowerPoint presentations, digital photos and digital video.

To ensure compatibility, all � les submitted must be in the formats listed below. Where new formats become available that might be acceptable, OCR will provide further guidance. OCR advises against changing the � le format that the document was originally created in. It is the centre’s responsibility to ensure that the electronic portfolios submitted for moderation are accessible to the moderator and fully represent the evidence available for each candidate.
