**KEPENTINGAN MENYERTAI PISA**

Menunjukkan tahap kesediaan murid Malaysia untuk menempuh alam dewasa Membolehkan penggubal dasar mendapat maklumat tepat mengenai sistem pendidikan bagi mengenal pasti ruang untuk penambahbaikan sistem pendidikan Membuat perbandingan prestasi dan persekitaran pembelajaran murid antara negara Menetapkan matlamat polisi seperti yang dicapai oleh negara lain dan belajar daripada polisi dan amalan di negara lain Salah satu daripada matlamat utama penggubal polisi adalah untuk membolehkan rakyat mendapat manfaat daripada ekonomi dunia yang bersifat global. Untuk itu, fokus yang lebih diberikan kepada penambahbaikan polisi pendidikan bagi memastikan perkhidmatan pendidikan yang berkualiti, peluang pendidikan yang saksama dan insentif diberi kepada kecekapan dalam proses pendidikan. Polisi sedemikian bergantung kepada maklumat yang tepat tentang sejauh mana sistem pendidikan menyediakan murid untuk menjalani kehidupan pada masa hadapan. Kebanyakan negara memantau pembelajaran murid dan prestasi sekolah. Walau bagaimanapun, dalam ekonomi global ini, kayu pengukur kejayaan sesuatu sistem persekolahan tidak lagi boleh diukur berdasarkan kepada standard kebangsaan sahaja tetapi mestilah dibandingkan dengan negara-negara lain pada peringkat antarabangsa.

**DEFINISI LITERASI MATEMATIK**

For the purposes of PISA 2015, mathematical literacy is defined as follows: Mathematical literacy is an individual’s capacity to formulate, employ, and interpret mathematics in a variety of contexts. It includes reasoning mathematically and using mathematical concepts, procedures, facts and tools to describe, explain and predict phenomena. It assists individuals to recognise the role that mathematics plays in the world and to make the well-founded judgments and decisions needed by constructive, engaged and reflective citizens.

**PISA FRAMEWORK CONTENT PROCESSES CONTEXT**

Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

17
**PISA FRAMEWORK Change and Relationship Space and Shape Quantity**

These four categories characterise the range of mathematical content that is central to the discipline and illustrate the broad areas of content used in the test items for PISA 2015: Change and Relationship Space and Shape Quantity Uncertainty and Data The four content categories serve as the foundation for identifying this range of content, yet there is not a one-to-one mapping of content topics to these categories. For example, proportional reasoning comes into play in such varied contexts as making measurement conversions, analysing linear relationships, calculating probabilities and examining the lengths of sides in similar shapes. The following content is intended to reflect the centrality of many of these concepts to all four content categories and reinforce the coherence of mathematics as a discipline. It intends to be illustrative of the content topics included in PISA 2015, rather than an exhaustive listing: Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

18
Functions: the concept of function, emphasising but not limited to linear functions, their properties, and a variety of descriptions and representations of them. Commonly used representations are verbal, symbolic, tabular and graphical. Algebraic expressions: verbal interpretation of and manipulation with algebraic expressions, involving numbers, symbols, arithmetic operations, powers and simple roots. Equations and inequalities: linear and related equations and inequalities, simple second-degree equations, and analytic and non-analytic solution methods Co-ordinate systems: representation and description of data, position and relationships. Relationships within and among geometrical objects in two and three dimensions: Static relationships such as algebraic connections among elements of figures (e.g. the Pythagorean theorem as defining the relationship between the lengths of the sides of a right triangle), relative position, similarity and congruence, and dynamic relationships involving transformation and motion of objects, as well as correspondences between two- and three-dimensional objects.

19
Measurement: Quantification of features of and among shapes and objects, such as angle measures, distance, length, perimeter, circumference, area and volume. Numbers and units: Concepts, representations of numbers and number systems, including properties of integer and rational numbers, relevant aspects of irrational numbers, as well as quantities and units referring to phenomena such as time, money, weight, temperature, distance, area and volume, and derived quantities and their numerical description. Arithmetic operations: the nature and properties of these operations and related notational conventions. Percents, ratios and proportions: numerical description of relative magnitude and the application of proportions and proportional reasoning to solve problems.

20
** Counting principles: Simple combinations and permutations.**

Estimation: Purpose-driven approximation of quantities and numerical expressions, including significant digits and rounding. Data collection, representation and interpretation: nature, genesis (raw data) and collection of various types of data, and the different ways to represent and interpret them. Data variability and its description: Concepts such as variability, distribution and central tendency of data sets, and ways to describe and interpret these in quantitative terms. Samples and sampling: Concepts of sampling and sampling from data populations, including simple inferences based on properties of samples. Chance and probability: notion of random events, random variation and its representation, chance and frequency of events, and basic aspects of the concept of probability.

**Contexts Personal Societal Occupational Scientific PISA FRAMEWORK**

An important aspect of mathematical literacy is that mathematics is engaged in solving a problem set in a context. Personal Societal Occupational Scientific For the PISA survey, it is important that a wide variety of contexts are used. This offers the possibility of connecting with the broadest possible range of individual interests and with the range of situations in which individuals operate in the 21st century. For purposes of the PISA 2015 mathematics framework, four context categories have been defined and are used to classify assessment items developed for the PISA survey:

**Computer-based Assessment**

In PISA 2015, for the first time, the computer will be the main mode of delivery for all tests and questionnaires. Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

32
**Why Computer-based Assessment?**

First, computers are now so commonly used in the workplace and in everyday life that a level of competency in mathematical literacy in the 21st century includes usage of computers (Hoyles et al., 2002). Computers now touch the lives of individuals around the world as they engage in their personal, societal, occupational and scientific endeavours. They offer tools for—among other things— computation, representation, visualisation, modification, exploration and experimentation on, of and with a large variety of mathematical objects, phenomena and processes. The definition of mathematical literacy for PISA 2015 recognises the important role of computer-based tools by noting that mathematically literate individuals are expected to use these in their endeavours to describe, explain, and predict phenomena. in this definition, the word “tool” refers to calculators and computers, as well as to other physical objects such as rulers and protractors used for measuring and construction.

A second consideration is that the computer provides a range of opportunities for designers to write test items that are more interactive, authentic and engaging (Stacey and Wiliam, 2013). These opportunities include the ability to design new item formats (e.g. drag-and-drop), to present students with real-world data (such as a large, sortable dataset), or to use colour and graphics to make the assessment more engaging

34
The suite of tools available to students is also expected to include a basic scientific calculator. Operators to be included are addition, subtraction, multiplication and division, as well as square root, pi, parentheses, exponent, square, fraction , inverse and the calculator will be programmed to respect the standard order of operations. PISA Editor tool Allow students to enter both texts and numbers. Students can enter a fraction, square root, or exponent. Additional symbols such as pi and greater/less than signs are available, as are operators such as multiplication and division signs.

35
The released PISA item Litter calls most heavily on students’ capacity for interpreting, applying, and evaluating mathematical outcomes. The focus of this item is on evaluating the effectiveness of the mathematical outcome—in this case an imagined or sketched bar graph—in portraying the data presented in the item on the decomposition time of several types of litter. The item involves reasoning about the data presented, thinking mathematically about the relationship between the data and their presentation, and evaluating the result. The problem solver must and provide a reason why a bar graph is unsuitable for displaying the provided data. Computer-based

PISA ITEMS 2 Litter For a homework assignment on the environment, students collected information on the decomposition time of several types of litter that people throw away: Type of litter Decomposition time Banana peel 1-3 years Orange peel Cardboard boxes 0.5 year Chewing gum 20-25 years Newspapers A few days Polystyrene cups Over 100 years Context: Scientific Content: Uncertainty & Data Process: interpreting, applying and evaluating mathematical outcomes This item is set in a scientific context, since it deals with data of a scientific nature (decomposition time). The mathematical content category is Uncertainty and data, since it primarily relates to the interpretation and presentation of data, although Quantity is involved in the implicit demand to appreciate the relative sizes of the time intervals involved. the mathematical process category is interpreting, applying and evaluating mathematical outcomes since the focus is on evaluating the effectiveness of the mathematical outcome (in this case an imagined or sketched bar graph) in portraying the data about the real world contextual elements. The item involves reasoning about the data presented, thinking mathematically about the relationship between the data and their presentation, and evaluating the result. The problem solver must recognise that these data would be difficult to present well in a bar graph for one of two reasons: either because of the wide range of decomposition times for some categories of litter (this range cannot readily be displayed on a standard bar graph), or because of the extreme variation in the time variable across the litter types (so that on a time axis that allows for the longest period, the shortest periods would be invisible). Student responses such as those reproduced in Figure 12 have been awarded credit for this item. A student thinks of displaying the results in a bar graph. Give one reason why a bar graph is unsuitable for displaying these data.

45
**PISA ITEMS 2 Sample responses for Litter**

Response 1: “Because it would be hard to do in a bar graph because there are 1-3, 1-3, 0.5, etc. so it would be hard to do it exactly.” Response 2: “Because there is a large difference from the highest sum to the lowest therefore it would be hard to be accurate with 100 years and a few days.” Communication comes in to play with the need to read the text and interpret the table, and is also called on at a higher level with the need to answer with brief written reasoning. The demand to mathematise the situation arises at a low level with the need to identify and extract key mathematical characteristics of a bar graph as each type of litter is considered. The problem solver must interpret a simple tabular representation of data, and must imagine a graphical representation, and linking these two representations is a key demand of the item. The reasoning demands of the problem are at a relatively low level, as is the need for devising strategies. Using symbolic, formal and technical language and operations comes into play with the procedural and factual knowledge required to imagine construction of bar graphs or to make a quick sketch, and particularly with the understanding of scale needed to imagine the vertical axis. Using mathematical tools is likely not needed. Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

Pizzas A pizzeria serves two round pizzas of the same thickness in different sizes. The smaller one has a diameter of 30 cm and costs 30 zeds. The larger one has a diameter of 40 cm and costs 40 zeds. Question 1 Which pizza is better value for money? Show your reasoning. Pizzas is set in a personal context with which many 15-year-olds would be familiar. The context category is personal since the question posed is which pizza provides the purchaser with the better value for the money. It presents a relatively low reading demand, thereby ensuring the efforts of the The open constructed-response item Pizzas shown in Figure 8 is simple in form, yet rich in content, and illustrates various elements of the mathematics framework. It was initially used in the first PISA field trial in 1999, then was released for illustrative purposes and has appeared as a sample item in each version of the PISA mathematics framework published since This was one of the most difficult items used in the 1999 field trial item pool, with only 11% correct. The item draws on several areas of mathematics. It has geometrical elements that would normally be classified as part of the Space and shape content category. The pizzas can be modelled as thin circular cylinders, so the area of a circle is needed. The question also involves the Quantity content category with the implicit need to compare the quantity of pizza to amount of money. However, the key to this problem lies in the conceptualisation of the relationships among properties of the pizzas, and how the relevant properties change from the smaller pizza to the larger one. Because those aspects are at the heart of the problem, this item is categorised as belonging to the Change and relationships content category. The item belongs to the formulating process category. a key step to solving this problem, indeed the major cognitive demand, is to formulate a mathematical model that encapsulates the concept of value for money. The problem solver must recognise that because pizzas ideally have uniform thickness and the thicknesses are the same, the focus of analysis can be on the area of the circular surface of the pizza instead of volume or mass. The relationship between amount of pizza and amount of money is then captured in the concept of value for money modelled as ‘cost per unit of area.’ variations such as area per unit cost are also possible. Within the mathematical world, value for money can then be calculated directly and compared for the two circles, and is a smaller quantity for the larger circle. The real world interpretation is that the larger pizza represents better value for money.

**An important part of formulation**

15 cm Employing knowledge from space and shape and Quantity. Formulating a mathematical model to measure value for money 20 cm The released PISA item Pizzas (see Appendix B) calls most heavily on students’ abilities to formulate a situation mathematically. While it is indeed the case that students are also called upon to perform calculations as they solve the problem and make sense of the results of their calculations by identifying which pizza is the better value for the money, the real cognitive challenge of this item lies in being able to formulate a mathematical model that encapsulates the concept of value for money. The problem solver must recognise that because the pizzas have the same thickness but different diameters, the focus of the analysis can be on the area of the circular surface of the pizza. The relationship between amount of pizza and amount of money is then captured in the concept of value for money, modelled as cost per unit of area. Interpreting mathematical result in real world terms.

**Computer-Based Assessment PISA 2015**

Single multiple-choice Full credit dependent on both the selection and the reasoning behind it. An alternative form of reasoning, which reveals even more clearly the item’s classification in Change and relationships, would be to say (explicitly or implicitly) that the area of a circle increases in proportion to the square of the diameter, so has increased in the ratio of (4/3),2 while the cost has only increased in the proportion of (4/3). Since (4/3)2 is greater than (4/3), the larger pizza is better value. While the primary demand and the key to solving this problem comes from formulating, placing this item in the formulating situations mathematically process category, aspects of the other two mathematical process are also apparent in this item. The mathematical model, once formulated, must then be employed effectively, with the application of appropriate reasoning along with the use of appropriate mathematical knowledge and area and rate calculations. The result must then be interpreted properly in relation to the original question. The solution process for Pizzas demands the activation of the fundamental mathematical capabilities to varying degrees. Communication comes in to play at a relatively low level in reading and interpreting the rather straight-forward text of the problem, and is called on at a higher level with the need to present and explain the solution. The need to mathematise the situation is a key demand of the problem, specifically the need to formulate a model that captures value for money. The problem solver must devise a representation of relevant aspects of the problem, including the symbolic representation of the formula for calculating area, and the expression of rates that represent value for money, in order to develop a solution. The reasoning demands (for example, to decide that the thickness can be ignored, and justifying the approach taken and the results obtained) are significant, and the need for devising strategies to control the calculation and modelling processes required is also a notable demand for this problem. Using symbolic, formal and technical language and operations comes into play with the conceptual, factual and procedural knowledge required to process the circle geometry, and the calculations of the rates. Using mathematical tools is evident at a relatively low level if students use a calculator efficiently.

**QUESTION INTENT: Applies understanding of area to solving a value for money**

comparison Code 2: Gives general reasoning that the surface area of pizza increases more rapidly than the price of pizza to conclude that the larger pizza is better value. • The diameter of the pizzas is the same number as their price, but the amount of pizza you get is found using diameter2 , so you will get more pizza per zeds from the larger one Code 1: Calculates the area and amount per zed for each pizza to conclude that the larger pizza is better value. • Area of smaller pizza is 0.25 x π x 30 x 30 = 225π; amount per zed is 23.6 cm2 area of larger pizza is 0.25 x π x 40 x 40 = 400π; amount per zed is 31.4 cm2 so larger pizza is better value Code 8: They are the same value for money. (This incorrect answer is coded separately, because we would like to keep track of how many students have this misconception). Code 0: Other incorrect responses OR a correct answer without correct reasoning. Code 9: Missing.

APARTMENT PURCHASE This is the plan of the apartment that George’s parents want to purchase from a real estate agency. Question 1: APARTMENT PURCHASE PM00FQ01 – 019 To estimate the total floor area of the apartment (including the terrace and the walls), you can measure the size of each room, calculate the area of each one and add all the areas together. However, there is a more efficient method to estimate the total floor area where you only need to measure 4 lengths. Mark on the plan above the four lengths that are needed to estimate the total floor area of the apartment. APARTMENT PURCHASE SCORING 1 QUESTION INTENT: Description: Use spatial reasoning to show on a plan (or by some other method) the minimum number of side lengths needed to determine floor area Mathematical content area: Space and shape Context: Personal Process: Formulate

**Full Credit A = (9.7m x 8.8m) – (2m x 4.4m) A = 76.56m2**

Code 1: Has indicated the four dimensions needed to estimate the floor area of the apartment on the plan. There are 9 possible solutions as shown in the diagrams below. A = (9.7m x 8.8m) – (2m x 4.4m) A = 76.56m2 [Clearly used only 4 lengths to measure and calculate required area.] No Credit Code 0: Other responses. Code 9: Missing.

**Question Question 1: SHAPES Which of the figures has the largest area?**

M158Q Question 1: SHAPES Which of the figures has the largest area? Explain your reasoning. SHAPES SCORING 1 QUESTION INTENT: Comparison of areas of irregular shapes Code 1: Shape B, supported with plausible reasoning. • It’s the largest area because the others will fit inside it. Code 8: Shape B, without plausible support. Code 0: Other responses. Code 9: Missing. Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

55
**Example responses Code 1:**

• B. It doesn’t have indents in it which decreases the area. A and C have gaps. • B, because it’s a full circle, and the others are like circles with bits taken out. • B, because it has no open areas: Code 8: • B. because it has the largest surface area • The circle. It’s pretty obvious. • B, because it is bigger. Code 0: • They are all the same. Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

M158Q Question 2: SHAPES Describe a method for estimating the area of figure C. SHAPES SCORING 2 QUESTION INTENT: To assess students’ strategies for measuring areas of irregular shapes. Code 1: Reasonable method: • Draw a grid of squares over the shape and count the squares that are more than half filled by the shape. • Cut the arms off the shape and rearrange the pieces so that they fill a square then measure the side of the square. • Build a 3D model based on the shape and fill it with water. Measure the amount of water used and the depth of the water in the model. Derive the area from the information. Code 8: Partial answers: • The student suggests to find the area of the circle and subtract the area of the cut out pieces. However, the student does not mention about how to find out the area of the cut out pieces. • Add up the area of each individual arm of the shape Code 0: Other responses. Code 9: Missing.

**to which the student describes a METHOD. Example responses Code 1: **

NOTE: The key point for this question is whether the student offers a METHOD for determining the area. The coding schemes (1, 8, 0) is a hierarchy of the extent to which the student describes a METHOD. Example responses Code 1: • You could fill the shape with lots of circles, squares and other basic shapes so there is not a gap. Work out the area of all of the shapes and add together. • Redraw the shape onto graph paper and count all of the squares it takes up. • Drawing and counting equal size boxes. Smaller boxes = better accuracy (Here the student’s description is brief, but we will be lenient about student’s writing skills and regard the method offered by the student as correct) • Make it into a 3D model and filling it with exactly 1cm of water and then measure the volume of water required to fill it up. wrong) Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

58
**• Minus the shape from the circle **

Code 8: • Find the area of B then find the areas of the cut out pieces and subtract them from the main area. • Minus the shape from the circle • Add up the area of each individual piece e.g., • Use a shape like that and pour a liquid into it. • Use graph • Half of the area of shape B • Figure out how many mm2 are in one little leg things and times it by 8. Code 0: • Use a string and measure the perimeter of the shape. Stretch the string out to a circle and measure the area of the circle using π r2. (Here the method described by the student is wrong) Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

**Describe a method for estimating the perimeter of figure C.**

Question 3: SHAPES M158Q Describe a method for estimating the perimeter of figure C. SHAPES SCORING 3 QUESTION INTENT: To assess students’ strategies for measuring perimeters of irregular shapes Code 1: Reasonable method: • Lay a piece of string over the outline of the shape then measure the length of string used. • Cut the shape up into short, nearly straight pieces and join them together in a line, then measure the length of the line. • Measure the length of some of the arms to find an average arm length then multiply by 8 (number of arms) X 2. Code 0: Other responses. Code 9: Missing. Bahagian Pembangunan Kurikulum Peneraju Pendidikan Negara

Question 3: SHAPES M158Q Describe a method for estimating the perimeter of figure C. Example responses Code 1: • Wool or string!!! (Here although the answer is brief, the student did offer a METHOD for measuring the perimeter) • Cut the side of the shape into sections. Measure each then add them together. (Here the student did not explicitly say that each section needs to be approximately straight, but we will give the benefit of the doubt, that is, by offering the METHOD of cutting the shape into pieces, each piece is assumed to be easily measurable) Code 0: • Measure around the outside. (Here the student did not suggest any METHOD of measuring. Simply saying “measure it” is not offering any method of how to go about measuring it) • Stretch out the shape to make it a circle. (Here although a method is offered by the student, the method is wrong)
