National Certificate of Educational Achievement

• Credits are the currency of the NCEA qualification.

• Students need a total of 80 credits for each NCEA qualification:• Generally speaking one credit represents ten hours of learning

and assessment. This includes teaching time, homework and assessment time.

• NCEA Level 1 – 80 credits at any Level, including credits in literacy(10) and numeracy(10).

• NCEA Level 2 – 60 credits at Level 2 or above, plus 20 credits from Level 1 or above. • NCEA Level 3 – 60 credits at Level 3 or above, plus 20 credits

from Level 2 or above. Introduction (http://www.nzqa.govt.nz/qualifications-standards/qualifications/ncea/understanding-ncea/the facts/factsheet-4/)

How many credits do students need?

Note - Students do not have to complete NCEA qualifications within a single school year - they can accumulate credits towards qualifications over any number of years.

• A typical course generates between 18 and 24 credits – so over five subjects, a typical student could aim for up to 120 credits.

• But schools can and do run courses that assess standards totalling as few as 12 credits, with others assessing 30 credits or more.

How many credits do students achieve?

The chart below shows the distribution of credits gained during 2010 by year 11, 12 and 13

students.

University EntranceUniversity Entrance (UE) is the minimum requirement to go to a New Zealand university. To qualify you will need:

Approved subjects - 42 credits at Level 3 or higher, made up of: • 14 credits in one approved subject • 14 credits in another approved subject• 14 credits from one or two additional domains or approved

subjects

Literacy requirements - 10 credits in English or te reo Maori at Level 2 or higher, made up of: 4 credits in reading and 4 credits in writingNumeracy requirements - 10 credits in Numeracy at Level 1 or higher, made up of credits in Mathematics or Statistics and Probability

Realignment of standards• Achievement standards and unit standards are being reviewed.

The review affected Level 1 in 2011, Level 2 in 2012, and will affect Level 3 in 2013. Some of the changes will impact on the mix of internal and external assessment.

• Achievement standards only will be used to assess curriculum linked knowledge and skills.

• Unit standards derived from the New Zealand Curriculum will be phased out, starting in 2011, and replaced with Achievement standards which are internally assessed.

• In each subject there will be a maximum of three externally assessed standards. This will change the ratio of internally and externally assessed standards that are available in some subjects.

• Unit standards will cover other skills and knowledge.

Achievement Criteria

Achievement Achievement with Merit Achievement with Excellence

Apply xxxxxxxx in solving problems.

Apply xxxxxxxxxxx, using relational thinking, in solving problems.

Apply xxxxxxxxxxx, using extended abstract thinking, in solving problems.

Explanatory NotesThis achievement standard involves applying xxxxxxxxxxxx in solving problems.•This achievement standard is derived from Level 8 of The New Zealand Curriculum, Learning Media, Ministry of Education, 2007; •and is related to the achievement objectives:

How do students gain credits?Achievement standards

External Standards• There will be an examination for each externally assessed

standard. Three externally assessed standards will be examined in a three hour examination. This will give students sufficient time to complete the examination and ensure assessment is reliable.

• Previously, in some subjects up to six standards were assessed in a three hour examination. This often resulted in students running out of time and leaving out important parts of the examination.

Course endorsementCourse endorsement was introduced in 2011 to recogniseexceptional achievement in an individual course.To gain a course endorsement:

• Students must gain 14 or more credits at Merit and/or Excellence within a school course.

• There must be a mix of internally and externally assessed credits– at least 3 credits from each (except in Physical Education, Religious Studies and Level 3 Visual Arts where there is no external assessment).

How are grades obtained?The SOLO taxonomy

SOLO stands for the Structure of Observed Learning Outcomes. It was developed by Biggs and Collis (1982). Biggs describes SOLO as “a framework for understanding”. (1999, p.37)

SOLO identifies five stages of thinking. Each stage embraces the previous level but adds something more in terms of the level of thinking.

A change of focus in mathematics

• The SOLO hierarchy shifts us from the situation in maths of “doing more” and “ doing longer tasks” to qualify for a higher grade.

• This change recognises and rewards deeper and more complex thinking along with more effective communication of mathematical ideas and outcomes.

• It is these that are fundamental competencies to mathematics.

The stages of SOLO• Prestructural

the student acquires bits of unconnected information that have no organisation and make no sense.

• Relational = Merit the students sees the significance of how various pieces of information relate to one another and know how and when to use strategies.

• Unistructural and Multistructural = Achieved students make connections between pieces of information using a known pattern

• Extended abstract = Excellence students make connections beyond the scope of the problem or question, to generalise or transfer learning into a new situation

A New Zealand tour company collected data over a period of a year to investigate information about its passengers.(a) It found that: • 48% of its passengers were male • 63% of its female passengers came from overseas • 21% of all passengers were males from overseas. You may assume that the event that a passenger is male and the event that a passenger is from overseas are independent. Find the probability that a randomly selected male passenger was from overseas.

The tour company decides to analyse its data in more depth.(a) It finds that: • the probability of an overseas passenger coming from Australia is 2/3 • the probability of an overseas passenger coming from Australia or aged over 30 is 3/4 • the probability of an overseas passenger coming from Australia and aged over 30 is 1/10. Find the probability that an overseas passenger is aged over 30.

In 2006, a survey was conducted on households in Hamilton, Canada.(a) Let the random variable X represent the number of cars in a randomly chosen household at the time of the survey. The survey gave the following probability distribution for X.x 0 1 2 3 4P(X = x) 0.059 0.383 0.377 0.153 0.028 Find the expected value of X.

Achieved is 2 out of 3

In summaryA student enrolling at UC who sat level 3 NCEA Calculus or Statistics and Modeling will have at least:-• 14 credits in 3 (or 4) approved subjects for UE+

literacy + 10 credits in mathematics at level 1 or better for numeracy

• sat achievement standards for 18 – 24 credits in calculus or stats and modeling

• Achieving 14 credits in calculus means basic competence in at least two of differentiation, integration and algebra
