welcome to ph3000 Welcome to the Level 3 Physics (PH3000) course offered by Te Aho o Te Kura Pounamu.

OVERVIEW OF PH3000 The PH3000 course offers a total of seven achievement standards. There are three externally assessed standards worth 16 credits and four internally assessed standards worth 13 credits. The PH3000 course consists of fourteen study booklets. Each study booklet takes around 10 hours of work. The number of booklets for each standard varies from two to four. Each booklet contains a teacher-marked assignment which takes about 2 hours to complete. This course can be endorsed with Merit or Excellence if in a single year you gain 14 or more credits at Merit and/or Excellence within Level 3 Physics. At least three of these credits must be from externally assessed standards and three from internally assessed standards.

getting started how this course is delivered

PH3000 is a print-based course, with course material and supplementary material accessed from the online teaching and learning environment (OTLE). Dual enrolled students are expected to access material from OTLE. Other enrolled students may request printed materials to be posted, accepting there will be a delay between enrolment and receiving the first posting. You will receive an email explaining how to log in to OTLE. This email includes a link to set your password if you have not logged into the OTLE before. You can access OTLE by clicking on www.tekura.school.nz/login. It is recommended that you bookmark this site in your browser. This will take you to a page with links to your courses. Your username and initial password is your Te Kura student ID number. You will be asked to set a new password when you first log in. After that, if you need to reset your password you can click on the ‘Forgot password’ link on the OTLE login page. If you have difficulties logging in, please email: helpdesk.otle@tekura.school.nz

organising your study

Plan a regular time to study. Some people learn best from frequent short sessions while others do better with fewer, longer sessions. It is important to have a plan or a timetable and to keep to it. There is a suggested course plan in the back of this guide to help you plan your programme of study. You may wish to consult with your subject teacher to help you decide on your plan. Getting your study underway is very important. Your first return of work should be two to three weeks after you received your initial work. If you have any issues returning your work within this time, please contact your subject teacher. For more information on how to study successfully, refer to the Student Guide to Years 11–13 (www.tekura.school.nz).

resources you need

•• Regular access to a computer, the internet, email and a printer will assist you with this course.

•• Write-in booklets, including inserts, will be sent to you. If you misplace a booklet or insert, contact your Physics teacher for a replacement copy. If possible, give the name and the code of the item to speed up the reordering process. •• Equipment boxes: most hands-on activities use everyday materials that are found in a typical home. There are three equipment kits that provide a few specialist items for studying Waves, Mechanics and Electricity. Equipment kits are not available to students who are overseas or who are studying in other schools. Full details of the requirements for each standard are listed at the beginning of each topic and on OTLE.

getting started

choosing topics and standards

NZQA advises that a one-year course should lead to 18–20 credits. You may only wish to study some topics. For example, you may want to do only internal standards for this course. You should look carefully at the course outline before you make your choices. It is important to consider how well this will meet your learning goals (such as gaining enough credits to achieve your NCEA Level 3, or whether you are working towards course endorsement, or meeting the entry requirements for your tertiary course or any future study). To be awarded University Entrance you must have: •• NCEA Level 3 •• Three subjects – at Level 3 or above, made up of: –– 14 credits each, in three approved subjects •• Literacy – 10 credits at Level 2 or above, made up of: –– 5 credits in reading –– 5 credits in writing •• Numeracy – 10 credits at Level 1 or above made up of: –– achievement standards – specified achievement standards available through a range of subjects, or –– unit standards – package of three numeracy unit standards (26623, 26626, 26627 – all three required). To see the list of approved subjects refer to: www.nzqa.govt.nz/qualifications-standards/awards/university-entrance/approved-subjects/ To see the list of standards which count towards University Entrance literacy refer to: www.nzqa.govt.nz/qualifications-standards/awards/university-entrance/literacy-requirementsfor-university-entrance-from-2014/ To see the list of standards which count towards University Entrance numeracy refer to: www.nzqa.govt.nz/qualifications-standards/qualifications/ncea/subjects/literacy-and-numeracy/ level-1-requirements/lit-num-subjects/ You should discuss your options with your learning advisor and/or your teacher.

self-assessment

Many activities are self-marked. Use the Answer guide at the back of each topic booklet to mark your own work and make corrections where necessary. Self-marking is important as it gives you instant feedback on how well you understand the ideas, concepts or information that have been covered. When you have finished a topic be sure to fill in the self-assessment section at the beginning of the teacher-marked assignment (TMA). Completing the self-assessment will help you to think about what you have learned. Research has shown that thinking about what you have learned helps to make learning more powerful. 4

assessment

Do not send in the self-marked work in your topic booklets. Each topic comes with a teachermarked assignment: this should be completed and sent to your teacher for assessment as soon as you finish the topic. Teacher-marked assignments are not for NCEA credit, but they will help you get practice at NCEA-style questioning, and you will get feedback from your teacher about the standard of your work. Send your work in by email if you can. Alternatively, post it back in the envelopes provided. Internal assessments for this course are: •• a practical investigation to test a physics theory (PH3012Y1) •• a report on the application of physics (PH3021Y1 or PH3022Y1) •• a test (PH3051Y1) •• a report on a physics-related issue (PH3071Y1). The detailed criteria for Achievement Standards will be given in the relevant resources. They can also be found by searching the subject and level in the NCEA part of the NZQA website (www.nzqa.govt.nz) and then finding the relevant standard(s). External assessment preparation includes: •• teacher-marked activities •• Te Kura practice examinations.

time commitment

NZQA recommends that students allow approximately 10 hours of study time per credit. A 3-credit standard would therefore take about 30 hours of study time. For example, PH3041 may take approximately 10 hours of work to complete at the normal pace, representing about two weeks of work at 6 hours per week. If you are to achieve at Excellence level, it is likely that you will have to study substantially more than the suggested guideline. Before deciding on the pace of learning, read through this Course and assessment guide and ask yourself the following: •• How much time can I set aside for study each week? •• Will I be attempting both externally and internally assessed standards? (Both are needed for Course endorsement) •• Will I be able to study for a minimum of five hours each week? •• Do I need specific external or internal credits for next year’s study or work?

normal pace of learning

As a guide, expect to do at least 6 hours work per week in this subject. This means completing three to four topics each term so that you complete the course before the external examination at the end of the school year.

flexible pace of learning

If you have less than a year because you start later or need to finish earlier, you can decide the pace at which you work. You could still complete 18–20 credits by devoting more time and effort to it. Your teacher can ensure that you receive the resources you need in time to do this.

cover sheets

The back cover of the teacher-marked assignment or assessment task becomes the cover sheet for your work. When you return one of these, remember to sign the cover sheet. Your supervisor also signs the cover sheet as part of our authenticity requirements. All students are encouraged to submit as much as possible of their work online via the OTLE Dropbox. When work requires authentication, students will follow the instructions provided in OTLE.

te kura codes

Your course code is: PH3000. PH is the code for Physics and 3 refers to Level 3. ‘PH’ refers to a resource that covers a particular learning topic in the PH3000 course. ‘PH3012Y1’ refers to the first assessment for an Achievement Standard (AS91521 Physics 3.1) for PH30000. ‘AS’ is the code for Achievement Standard.

queries about your work

It is important to contact your teacher if you have any queries about your work. It helps to have your ID number, resource code (for example, PH3031) and the activity or question number when you contact your teacher, but it is not essential.

assessment information standards

PH3000 offers credits from Achievement Standards which count towards NCEA Level 3. In 2013, some Unit Standards are also available. For more details about Unit Standards, see the Te Kura website or contact your teacher. Please refer to our Student Guide to National Certificates or Te Kura and New Zealand Qualifications Authority (NZQA) websites for more information about National Certificates of Educational Achievement, and assessment: •• www.nzqa.govt.nz •• www.tekura.school.nz

internal assessment

PH3000 offers four Achievement Standards that are internally assessed. This means that your teacher sets and marks all assessments that count towards credits gained for these standards. The assessment opportunity for an Achievement Standard is coded ‘Y1’ and if there is a second assessment opportunity offered, this is coded ‘Y2’. For example, PH3012Y1 is the first assessment for AS91521 and PH3012Y2 is the second assessment opportunity.

external assessment

External assessment means that an external examiner marks your assessment work. This is through the NZQA examinations at the end of the year. You will be able to complete practice assessments and Te Kura practice examinations for external standards.

te kura practice examinations

You should complete the Te Kura practice examinations in Term 3. It is important that you complete all practice external assessments and examinations. If for some reason, such as illness, you are unable to sit the NZQA examinations at the end of the year you will only be eligible for consideration for a derived grade (compassionate consideration) if you have completed the Te Kura practice examinations.

resubmissions for internal assessments

If you have made mistakes in your standard assessment activity, your teacher may offer you one resubmission opportunity. This means you have made errors that you are capable of discovering and correcting by yourself. A resubmission allows you to correct your errors and improve your result.

further assessment opportunities for internal assessments For some standards, you may be able to complete a second assessment called a ‘further assessment opportunity’ to improve your results. These standards are indicated in the assessment summary. You should take this opportunity where it is available.

assessment information

authenticity

Authenticity means that students complete and submit work that is their own. When you submit work to Te Kura, you sign an authentication declaration that the work you are submitting is your own work and was done under the required assessment conditions. Where applicable, your supervisor signs to confirm this declaration. When submitting work online via the OTLE Dropbox, if it requires authentication, students must follow the instructions provided in OTLE.

derived grades (compassionate consideration)

If for any unexpected reason you are not able to sit your end of year examination or to submit final work towards an external standard (portfolios or projects), you may be eligible for a derived grade. Please refer to the Student Guide to National Certificates and contact your teacher or learning advisor as soon as possible to find out more should you feel this is necessary.

appeals

You have the right to query an assessment result if you want further clarification or disagree with the result. If you are still not satisfied, you may appeal. Refer to the Student Guide to National Certificates for more information. You can also appeal any other decisions, procedures or policies about assessments. Contact your teacher or learning advisor if you wish to appeal. Further information and a form that students can use to appeal is available on the Te Kura website in the Student toolkit area (www.tekura.school.nz and go to Student toolkit).

new zealand scholarship

New Zealand Scholarship examinations are designed to extend very high achieving Level 3 NCEA students. Students who wish to enter for the NZ Scholarship examinations must discuss this option with their Te Kura subject teacher. The list of subjects available for NZ Scholarship can be found at: www.nzqa.govt.nz/qualifications-standards/awards/scholarship/scholarship-subjects/

ph3000 sample course planner NZQA recommends that students complete 18–20 credits in one academic year. You should design your course in consultation with your teacher. Remember that you should allow 10 study hours per credit, and make sure that you are aiming for the standards that will help you towards your long-term goals. In this example, the student has chosen the three externals (16 credits) plus the internal, Modern Physics (3 credits). This is normally recommended for students who want to pursue science related courses at higher level. Choosing PH3.1 (Practical investigations), PH3.2 (Physics application) or PH3.7 (Physics in Society) standards would allow the student to gain credits in internally assessed standards. You must complete a booklet and return a teacher marked assessment to your teacher in every two weeks. Study plan Term 1
