The Programme
for International Student Assessment (PISA) is a project of the Organisation
for Economic Co-operation and Development (OECD). PISA seeks to assess how well
15-years-olds are prepared for life’s challenges. And assess students in three
different domains: reading, mathematics and science.
Content,
contexts, competencies and mathematical literacy are building blocks for the
PISA mathematics framework. The process of “mathematisation” describe the
ability of student to solve real world problems by shifting between real world
and mathematical world contexts.
PISA
organizes mathematical content into four overarching ideas:
a. Change
and Relationships
Change
and relationships involves the knowledge of mathematical manifestations of
change, as well as functional relationships and dependency among variables
b. Space
and Shape
Space
and shape relates to the understanding of spatial and geometric phenomena and
relationships
c. Quantity
Quantity
requires an understanding of numeric phenomena, quantitative relationships and
patterns
d. Uncertainly
Uncertainly
involves probabilistic and statistical phenomena as well as relationships that
become increasingly relevant in the information society
For certain topics and groups of
countries, PISA mathematics questions are reclassified into five traditional curriculum
topics: Number, Algebra, Measurement, Geometry and Data.
PISA mathematics questions are set
in four different contexts:
a. Personal
The
unit SKATEBOARD contains three questions, Q1, Q2 and Q3, classified
in
the personal context, day-to-day activities.
b. Educational
and occupational
The
educational and occupational contexts include problem situations that students
might confront while at school, including those rather artificial problems
designed
specifically for teaching or practice purposes, or problems that would
be
met in a work situation
c. Public
Public
contexts are those situations experienced in one’s day-to-day interactions with
the
outside world
d. Scientific
(including intra-mathematical)
and
scientific or explicitly mathematical problems.
PISA groups the underlying skills
into three competency clusters:
a. Reproduction
those
involving familiar mathematical processes and computations
b. Connections
those
involving a degree of interpretation and linkages
c. Reflection
those
involving deeper insights and reflection
PISA mathematics questions cover a
wide range of difficulties in a wide range of formats. The difficulty of PISA
mathematics questions is determined using three different approaches: with simple
percentages, logistic models, and the statistically calculated PISA mathematics
scale. Student performance is measured on a scale with an average score of 500.
Students are grouped in six levels of proficiency, plus a group below Level 1.
Differences in curricula and traditions,
and in grade level partly explain performance patterns across countries. The
chapter concludes with examination of item difficulty by competency clusters
and context areas by country and overall. Previous research identifies four groups
of countries with similar performance:
a. English-Speaking
Group: Australia, Canada, England,
Ireland, New Zealand, Scotland and the United States.
b. Post-Communist
Group: Bulgaria, Czech Republic,
Hungary, Latvia and Lithuania, The Russian Federation, Romania, Slovak Republic
and Sloveni
c. Nordic
Group: Denmark, Iceland, Norway and
Sweden.
d. Eastern
Asian Group: Hong Kong-China, Japan,
Korea, and Singapore.
Performance patterns in PISA
questions can provide useful insights for curriculum design, PISA questions can
be classified by traditional mathematic domains, Algebra and Measurement are relatively
more difficult, while Data, Geometry and Number are easier. Across domains, one
can identify different country groups.
Students from higher grades perform
better. An analysis of the performance differences across grades shows that student
performance is closely related with instruction. Across competency clusters,
Reproduction was the easiest and Reflection the most difficult. Both competency
clusters and traditional domains are related to the difficulty of PISA
questions. PISA questions presented
in a personal context were easier than those in other contexts. Conclusion : Performance
in PISA is related to curriculum and instruction, Patterns of performance
emerge across countries, grades, competency clusters, and contexts.
PISA can also be used to analyse
student strategies and misconceptions. Mathematisation refers to the
problem-solving process students use to answer questions. The mathematisation cycle,
and the three phases of mathematisation:
a. Phase
1. Understanding the question (e.g.
dealing with extraneous data), which is also called horizontal mathematisation.
b. Phase
2. Sophistication of problem-solving
approaches, which is also referred to as vertical mathematisation.
c. Phase
3. Interpretation of mathematical
results (linking mathematical answers to the context
The coding of PISA questions
provides clues to the student’s understanding, Double coding can help
disentangle student’s problemsolving strategies and understanding. Conclusion :
The PISA Framework of mathematical literacy (OECD, 2003) described the
problemsolving process in terms of the process of “mathematisation”. This
chapter presented two examples of PISA items that make the problem-solving
cycle visible. In these examples the problem-solving cycle comes alive in
almost all aspects of the questions. Each problem solving strategy was not a
routine procedure. Unfortunately the authors cannot shed light on the actual
specific strategy students used. The PISA scoring format does not provide
specific information on the thinking and argumentation processes students actually
used in solving problems.At the level of daily practices of instruction in
schools, however, it is possible to ask additional questions and, particularly,
let students give arguments for their solutions. Teachers and other researchers
might try using PISA items with their students and compare their results with
those observed in this chapter.
