Introduction

BackgroundThe Key Stage 3 National Strategy aims to raise standards by strengtheningteaching and learning across the curriculum for all 11–14-year-olds. It is basedon four important principles:

� expectations: establishing high expectations for all pupils and settingchallenging targets for them to achieve;

� progression: strengthening the transfer from Key Stage 2 to Key Stage 3 andensuring progression in teaching and learning across Key Stage 3;

� engagement: promoting approaches to teaching and learning that engageand motivate pupils and demand their active participation;

� transformation: strengthening teaching and learning through a programme ofprofessional development and practical support.

The 2001 Green Paper Schools: Building on Success proposed a two-year KeyStage 3 pilot and this was initiated in February 2003 as part of the Key Stage 3National Strategy. The aims of the project are to develop ways of completingprogrammes of study for Key Stage 3 in two years that will:

� increase the pace of learning and raise standards;

� enhance pupils’ motivation and engagement;

� improve transfer between Key Stage 2 and Key Stage 3;

� increase curriculum flexibility through the use of saved time in Key Stage 3and throughout the 14–19 phase.

About this documentThis guidance is intended to help departments in planning to meet the NationalCurriculum requirements for science when they are designing a condensed KeyStage 3 curriculum. It has been based on early lessons from the two-year KeyStage 3 project. This is an ongoing project that is still being evaluated andconsequently this guidance may be subject to further revisions. This guidancehas been written as a supplement to the Framework for teaching science: Years7, 8 and 9 (DfES 0136/2002) and should be read in conjunction with that

This document contains:

� a set of the yearly teaching objectives from the Framework for teachingscience: Years 7, 8 and 9 (DfES 0136/2002) organised for a condensed KeyStage 3 programme. It is important to note that this represents only oneexample of how the yearly teaching objectives for Years 7, 8 and 9 may becovered in two years. The objectives in this document are the same as thosein the Framework;

� an example showing how a department might plan to cover the yearlyteaching objectives over a six-term condensed Key Stage 3;

� an example of a process for deciding how individual units from the non-statutory DfES/QCA scheme of work for Key Stage 3: science (QCA 0045)might be combined to support a two-year science curriculum.

The explorative nature of a condensedKey Stage 3The two-year Key Stage 3 project is explorative. The examples and suggestionscontained in this guidance are therefore tentative. The impact of the project isbeing evaluated by Ofsted and NfER/LSE. Their final reports are not due to besubmitted until autumn 2006. Consequently, lessons will be drawn from theevaluation as it proceeds.

Pupils have only one opportunity to learn and achieve in Years 7, 8 and 9. Anyschool contemplating a two-year Key Stage 3 should be confident thatparticipating pupils would achieve at least the same level of success in thecondensed Key Stage 3 curriculum as they would have in three years. Equally itis important for the school to have systems in place that will enable pupilsfollowing a condensed programme in Years 7 and 8 to revert to a three-yearprogramme if their learning is not on target to meet at least national expectationsby the end of Year 8.

Designing a flexible Key Stage 3 curriculumAn important principle is that a condensed Key Stage 3 programme shouldprovide pupils with a rich, challenging and engaging curriculum that will enablethem to achieve standards at least as high as those they would have achievedhad they studied the programme over three years.

Teachers should think about science in the context of the whole-schoolcurriculum when considering whether or not to implement a condensed KeyStage 3 programme. They should reflect on their reasons for considering acondensed programme and which pupils are likely to benefit. For example, acondensed programme may better meet the needs of all pupils, or it may only beappropriate for a particular group of pupils. Having reflected on these issues,teachers will need to consider the design of the condensed programme of study.One possible sequence for designing a flexible science curriculum is set out onthe following page.

Introduction

Discuss as a school (in senior leader/subject leader/department meetings)principles, opportunities, constraints and your aims for the condensed Key

Stage 3 within the context of the whole-school 11–19 curriculum. Agree the allocation and distribution of teaching time.

Review your current scheme of work to identify strengths and ascertainwhat changes you need to make to support an effective Key Stage 3curriculum, bearing in mind the need to cover the National Curriculum

programme of study.

Plan units of work that ensure coverage of the programme of study.Amend your existing scheme of work as appropriate or, if nesessary,

design a new scheme of work from first principles. Use the yearlyobjectives and additional guidance to identify progression and set an

appropriate level of challenge.

Define and agree pupils’ expected levels of attainment at the end of thecondensed key stage.

Ensure that you have effective systems for tracking and responding topupils’ progress.

Decide how you are going to group the pupils in order to maximise theprogress of all concerned.

Identify which groups/pupils might need additional support.Decide how you are going to allocate teachers to groups.

Introduction

Sufficient time needs to be allowed to enable teachers to review the programme ofstudy and make the necessary revisions to plans. Detailed planning of completeschemes of work in advance, at least for the first year of a condensedprogramme, will help to ensure continuity and progression and appropriatecoverage of the programme of study. It will also avoid additional pressure ondepartments later in the year. Departments will also need time to review schemesof work and pupils’ progress over the year so that they can refine future planning.

The National Curriculum handbook for secondary teachers in England describesa set of aims for the school curriculum. A school should provide a balanced andbroadly-based curriculum for all pupils which:

� provides opportunities for all pupils to learn and achieve;

� promotes pupils’ spiritual, moral, social, cultural, mental and physicaldevelopment;

� prepares pupils for the opportunities, responsibilities and experiences ofadult life.

These interdependent aims for the school curriculum cannot be fully achievedwithout the provision of PSHE. A condensed curriculum should therefore reflectthe importance of PSHE and schools need to consider carefully how theguidelines in the non-statutory Framework, together with the statutory sex,relationship and drugs education curriculum, will be delivered.

Page 12: A condensed Key Stage 3: Supplementary guidance – sciencewsassets.s3.amazonaws.com/ws/nso/pdf/5a4310dabf19f... · a set of the yearly teaching objectives from the Framework for

When designing a condensed Key Stage 3 curriculum in science, it is importantto ensure that it fully meets the requirements of the statutory Key Stage 3programme of study for science and that it:

� reflects the school’s character and ethos;– for example, if a school has a particular focus on developing ICT across

the curriculum, then the science curriculum should provide pupils withappropriate planned opportunities to both use and develop their ICTskills within their science lessons;

– it supports the school’s aims for condensing the key stage;

� is broad and balanced;– it will enable pupils to cover the whole of the National Curriculum

programme of study, including the requirement to teach abouthuman reproduction. During Key Stage 3, all pupils should be taught:about the physical and emotional changes that take place duringadolescence; about the human reproductive system, including themenstrual cycle and fertilisation; how the foetus develops in the uterus,including the role of the placenta;

– it gives appropriate emphasis to the different strands of the programmeof study. In particular, it is important that the processes of scientificenquiry receive as much attention as the facts, skills and conceptscontained within the sections on life processes and living things,materials and their properties, and physical processes.

– it takes account of, and includes opportunities to teach pupils about,hazards, risks and risk control;

� is inclusive;– it should be accessible to, and engage and inspire, all targeted pupils;– it develops and extends pupils’ knowledge and understanding of science

using engaging and interesting contexts for learning, including practicalwork and contemporary science;

– a condensed curriculum should not be used as a vehicle for disapplyinglower-attaining pupils;

– if the curriculum is being condensed for higher-attaining pupils only, thisshould not limit new opportunities for the other pupils;

� builds on what pupils already know, understand and can do;– the curriculum in the autumn term is planned in such a way that it

smooths the transfer from Key Stage 2 to Key Stage 3. It is differentiatedappropriately, based on Key Stage 2 test levels, raw scores andqualitative information;

– the curriculum enthuses pupils through communicating high expectationsof what they can achieve;

� is planned within the context of the whole 11–19 curriculum;– the opportunities offered by the released time are carefully thought

through and planned in sufficient detail to ensure continuity andprogression either to or from the condensed programme;

– consideration is given to how pupils will be able to move betweendifferent curriculum pathways both within Key Stage 3 and beyond;

– expectations for pupil attainment at the end of the condensedprogramme are clarified at the outset;

� ensures that connections between scientific ideas and across the curriculumare emphasised;– key scientific ideas are presented in an interrelated way to enable pupils

to make sense of the subject;– the curriculum helps pupils to appreciate the importance of science by

establishing links with other subjects. For example, there is collaborationbetween science and history teachers when planning a history unit ‘Howhas 20th-century medicine changed people’s lives?’ and collaborationbetween science and geography teachers when planning a geographyunit ‘Can the earth cope?’;

– practical work is used to give pupils first-hand experience of the way thatscientific ideas are developed through using empirical evidence andcreative thinking;

� makes links with the PSHE Framework through teaching and learning onhealth, drugs (including medicines), sex education and safety.

Introduction

Organising teaching timeThere are no prescribed time allocations for individual subjects. It is up to eachschool to determine the amount of time needed to teach the science curriculumeffectively and for its pupils to cover the programme of study successfully. TheKey Stage 3 National Strategy booklet Designing the Key Stage 3 curriculum(DfES 0003/2002) identified the following averaged time allocations for scienceover the three years of the key stage.

In reducing the overall number of weeks available for teaching the scienceprogramme of study from 108 to 72 for example, schools will need to considercarefully the way that teaching time is organised in order to maximiseopportunities for learning for all pupils.

Schools need to identify how much of the PSHE programme will be deliveredthrough discrete curriculum time and how much will be taught through othercurriculum areas and activities, including science.

When considering the most effective way of organising the teaching time, it isimportant to decide:

� how the total number of hours available for teaching science should bedistributed across the condensed key stage;

� the most effective way of distributing the teaching time across a term orteaching week;

� how the distribution of the teaching time reflects the needs of differentgroups of pupils.

Further guidance on organising teaching time may be found in A condensed KeyStage 3: Designing a flexible curriculum (DfES 0798-2004).

Reviewing and modifying a scheme of workfor scienceThe National Curriculum programme of study for science is the statement of thestatutory learning entitlement for all pupils. When following the Key Stage 3programme of study, pupils need to be supported to:

� build on their existing scientific knowledge and understanding;

� make links between different areas of science;

� use scientific ideas and models to explain phenomena and events.

However a school decides to structure a flexible Key Stage 3 science curriculum,the National Curriculum programme of study is the starting point for decidingwhat pupils should be taught.

Introduction

Stages in planning a science scheme of work

Although the Key Stage 3 programme of study for science must be taught to allpupils in its entirety, schools have considerable freedom to decide which parts toemphasise and which to cover more lightly so that they can give all pupils a richand balanced curriculum.

The Framework for teaching science: Years 7, 8 and 9 (DfES 0136/2002) is non-statutory guidance built around a body of yearly teaching objectives in scientificenquiry and five key scientific ideas:

� cells;

� interdependence;

� particles;

� forces;

� energy.

The Framework will help departments to plan and modify an effective scheme ofwork that incorporates progression. It is important to note that, although theyearly teaching objectives identify for each year the core of what pupils shouldknow and understand about scientific enquiry and the key ideas, they do notcover the whole Key Stage 3 programme of study and so do not form a sciencecurriculum on their own.

The non-statutory DfES/QCA scheme of work for Key Stage 3: science (QCA0045) and its accompanying teacher’s guide are a useful resource when planning

how to modify an existing scheme of work for a condensed Key Stage 3. Inparticular, Appendix 1 and Appendix 2 are helpful in monitoring the extent towhich your modified scheme:

� covers the programme of study adequately;

� is structured to support progression in scientific enquiry and the key scientificideas;

� is sequenced to make the best use of the resources available in the sciencedepartment.

Questions to be answered in modifying a scheme of work include the following.

� Which units are the most useful in supporting progression by being goodvehicles for the yearly teaching objectives?

� Which units can be usefully combined?

� Are there units that can be given a light touch or safely be omitted?

� Are effective links with other parts of the curriculum safeguarded?

Further guidance on planning can be found in section 4 of the Framework.

Consolidating knowledge, skills andunderstandingIn a flexible key stage where the curriculum may be condensed, the timeavailable to consolidate and practise knowledge, skills and understanding maybe reduced. Consequently, departments need to guarantee that they providesufficient opportunities for pupils, especially those with weaker literacy andnumeracy skills, to consolidate and practise what they have learned and reflecton their learning. This involves ensuring that:

� time is used effectively to focus on understanding, key ideas and concepts,patterns and relationships;

� there is an emphasis on activities and questions that encourage pupils tothink and make decisions;

� activities encourage pupils to use and apply knowledge, skills andunderstanding in a range of familiar and unfamiliar contexts;

� opportunities are identified that enable pupils to use and apply knowledge,skills and understanding across the curriculum;

� lesson starters are used effectively to practise and consolidate key skills;

� effective use is made of learning opportunities outside lessons, includinghomework;

� teaching focuses on key skills that are transferable, and develops pupils’ability to solve problems rather than follow rules.

Introduction

Increasing the pace of learningIncreasing the pace of learning is not the same as increasing the pace ofteaching. Furthermore, increasing the pace of teaching does not in itself increasethe pace of learning. Increasing the pace of teaching may lead to more of thecurriculum being covered, but pupils may be hurried and moved on to a newtopic before they have had the opportunity to consolidate their learning.

To increase the pace of learning, planning needs to:

� remove areas of duplication and combining related aspects of study in ascheme of work;

� identify opportunities in other curriculum areas where key ideas from sciencecan be reinforced and applied in new contexts. This may be managedthrough drawing on common content, developing common skills or usingcontent from another subject as a stimulus for learning;

� ensure a purposeful start to the first year of Key Stage 3 by effective transferfrom Key Stage 2. This includes responding to the fact that some of thescience topics taught in Key Stage 3 build directly upon what pupils havealready learned in Key Stage 2, whereas some of the ideas are new andintroduced in Key Stage 3.

Knowledge about the Key Stage 2 programme of study and Science: a schemeof work for Key Stages 1 and 2 (QCA /98/211/50) should inform decisions aboutwhere and when yearly teaching objectives should be taught and assessed in aflexible Key Stage 3 curriculum to maintain continuity and ensure progression.

To increase the pace of learning, planning needs to:

� establish clear and purposeful classroom routines that help pupils toconcentrate on their learning;

� identify learning activities that develop pupils’ higher order skills such asenquiry, analysis and evaluation;

� provide opportunities for pupils to construct meaning, recognising that thismay take more time, but will improve learning;

� teach for metacognition – provide opportunities for pupils to reflect on theirthinking;

� emphasise the key ideas and help pupils to make connections by planninglearning activities that involve a group of objectives, perhaps clusteredaround a key objective;

� extend thinking – where there is a clear strand of progression, objectivesfrom subsequent years can be used to accelerate learning;

� explicitly teach pupils the skills and attitudes that will help them to becomeindependent learners;

� identify learning objectives within a unit of work or a lesson and be clearabout intended learning outcomes – what precisely the teacher expectspupils to be able to do at the end of that unit or lesson;

� structure units of work and lessons into ‘episodes’ – distinct stages oflearning – allocating most time to developing the key ideas;

� make more effective use of time across units of work and within lessons;

� ensure that individual episodes within a lesson do not exceed theconcentration span of pupils. For example, in Key Stage 3 episodes mightnormally last less than 15 minutes.

Introduction

Assessment and target settingProviding challenge and raising pupils’ achievement are important criteria forjudging the success of a condensed Key Stage 3. It is important that teachersmake good use of all the information available to them about their pupils’previous attainment in science if the pupils are to make a successful start to thecondensed Key Stage 3 curriculum and maintain progress throughout.

A ‘clean sheet’ approach at the beginning of Year 7 is impractical andundervalues what has been achieved in earlier key stages. It allows pupils tocoast or fall back when they need to be challenged. Science departments needto make early decisions about what their pupils already know, understand andcan do, based on numerical data such as Key Stage 2 national test levels, rawscores and end-of-Key Stage 2 teacher assessments. Teachers of Year 7 pupilswill want to use this information and subsequent assessments to ensure thattheir teaching is targeted at the appropriate level and that an appropriate pace oflearning for all pupils is maintained.

In a condensed Key Stage 3, it is vital that teachers know what pupils arecapable of achieving and pupils know what is expected of them. Settingcurricular targets for pupils that are linked to the teaching objectives to becovered in a unit will help pupils and teachers to focus on their learning.Negotiating curricular targets with pupils will also promote reflection and increasethe pace of learning by helping them to become increasingly independentlearners. Additional guidance on setting and using curricular targets can befound in Assessment for learning (DfES 0043-2004 G).

Further guidance on assessment and target setting can be found in section 6 ofthe Framework for teaching science: Years 7, 8 and 9 (DfES 0136/2002) and theQCA Assessing progress in science materials (QCA/03/1145)

A key decision when the Key Stage 3 programme of study is covered in Years 7and 8 is whether pupils should be entered for the National Curriculum tests atthe end of Year 8 or Year 9. It is vital that a school establishes and agrees criteriafor deciding when pupils should be entered for National Curriculum tests and itshould not be assumed that all pupils would be entered at the end of Year 8. Apupil should only be entered for a National Curriculum test early if theheadteacher judges that they have completed the programme of study, are readyto move on to the Key Stage 4 programme of study, and have attained at leastthe nationally expected standard of level 5/6.

� Explain how scientific ideas have changedover time; describe some of the positive andnegative effects of scientific and technologicaldevelopments.

� Select and use a suitable strategy for solvinga problem; identify strategies appropriate todifferent questions, including those in whichvariables cannot be easily controlled.

� Make sufficient systematic and repeatedobservations and measurements withprecision, using an appropriate technique.

� Use appropriate range, precision andsampling when collecting data during ascientific enquiry, and explain why these andcontrolled experiments are important.

� Select and use appropriate methods forcommunicating qualitative and quantitativedata.

� Describe patterns in data; use scientificknowledge and understanding to interpret thepatterns, make predictions and checkreliability.

� Draw conclusions from their own data anddescribe how their conclusions are consistentwith the evidence obtained, using scientificknowledge and understanding to explainthem.

� Consider whether an enquiry could have beenimproved to yield stronger evidence, e.g.improving the accuracy or sufficiency ofmeasurements or observations; explain anyanomalous results.

� Describe how evidence or the quality of theproduct supports or does not support aconclusion in their own and others’ enquiries;identify the limitations of data in conclusions.

� Consider early scientific ideas, including howexperimental evidence and creative thinkinghave been combined to provide scientificexplanations and how some early scientificideas do not match present-day evidence.Describe how new creative thinking has beenused to provide a scientific explanation.

Using and modifying theDfES/QCA scheme of workfor Key Stage 3: scienceThe table below suggests one possible way that the units from the QCA schemeof work for Key Stage 3 might be sequenced to support pupils’ progression inthe key ideas and yearly teaching objectives. Many other routes are possible.The table is not intended to imply that all of the units must, or even should, beused or that any individual unit cannot be modified or combined with others.

YEAR 1

Particles, forces, energy (Autumn term)7G Particle model of solids, liquids and gases, 7H Solutions, 7A Cells, 7B Reproduction, 7K Forces and their effects, 7I Energy resources

Particles, cells, energy (Spring term)8E Atoms and elements, 7E Acids and alkalis, 7F Simple chemical reactions, 8G Rocks and weathering, 8A Food and digestion, 8C Microbes and disease,7J Electrical circuits

The time allocation for each QCA unit assumes a three-year Key Stage 3. Forthis reason, to ensure that their science curriculum is broad, balanced, engagingbut also manageable in the time available, science subject leaders will need tomake careful decisions about:

� which units they will use;

� which will be shortened or cut completely;

� which units are the most useful in supporting progression by being goodvehicles for assessing the yearly teaching objectives;

� which units can be usefully combined to emphasise connections and keyscientific ideas;

� safeguarding effective links with other parts of the curriculum.

EXAMPLE

How units can be modified and combined

A science department agrees a map for progression in the key idea ofparticles in Key Stage 3. Following discussion and supported by the KeyStage 3 science consultant, the department uses its progression map toinform how the yearly teaching objectives will be distributed in thecondensed Key Stage 3 curriculum.

As part of its more detailed medium-term planning the department decidesto amalgamate some units – 7G Particle model of solids, liquids and gases,7H Solutions and 8H The rock cycle – because taken together theysupport all of the yearly teaching objectives for particles in Year 7.

The Key Stage 3 science coordinator works with subject specialists in thedepartment and uses the department’s agreed progression map and theFramework to decide:

� which parts of the units support the yearly teaching objectives moststrongly;

� the order in which to teach the content of the units to support thedepartment’s progression map;

� which parts of the units contain ideas previously learned in primary school;

� which parts of the units may be given a light touch or safely omitted;

� whether or not the new unit can be extended to include appropriateyearly teaching objectives for particles from Year 8;

� which aspects of scientific enquiry will be emphasised in theamalgamated unit;

� the amount of teaching time to allocate to the new unit;

� an effective starting point for teaching and opportunities to review andassess work with pupils.

A summary of the outcome appears below.

PurposeTo support the Year 7 yearly teaching objectives for the key scientific idea ofparticles for a two-year Key Stage 3 science curriculum.DfES/QCA units:� 7G Particle model of solids, liquids and gases� 7H Solutions

Aspects of the two units retained and emphasised to supportprogression and the yearly teaching objectives for Year 7� How are theories created? (7G)� What are the differences between solids, liquids and gases? (7G)� How can the particle model explain the differences between solids, liquids

and gases? (7G)� How can the particle model explain other phenomena? (7G)� What happens to the solute when a solution is made? (7H)� Is there a limit to the amount of solid that will dissolve in a liquid? (7H)� What else affects solubility? (7H)

Aspects added to extend the coverageTeaching and learning about part of the Year 8 yearly teaching objectiveconcerned with how the rate of cooling of solutions and molten materialaffects crystal size, and using the particle model to explain the observations.(Compare with aspects of DfES/QCA Unit 8H The rock cycle.)

Focus for scientific enquiry yearly teaching objectives� Consider how experimental evidence and creative thinking have been

combined to provide scientific explanations.� Use appropriate equipment to make observations and measurements

correctly.� Present and interpret experimental results through simple graphs.

Starting point for the unit‘What will happen to this salty water if I leave it out on the bench for 24hours?’ Pupils share ideas based on their learning from Key Stage 2 anddiscuss what they understand about the relationship between theories,experiments and evidence.

Assessment� Mid-unit: outcomes of pupils’ ideas of applying the particle theory to a

range of other phenomena.� End of unit: outcomes of pupils investigating and explaining the effects of

cooling on crystal size.

The new unit is included in the department’s overall plan for schemes of workas part of the teaching programme for the first term of Year 7.

The science subject leader and/or Key Stage 3 science coordinator monitorthe teaching and learning of the new unit to collect evidence for a planneddepartmental evaluation meeting that informs its first review.
