About this talk
My selected work as a response to
“manifestations of MPP” by Silver (2013) and
“teaching and learning through MPP” by English (2020).
Sharing results of analyses to data from Taiwan, Hong Kong and US. This research agenda grew over time with participants that were initially students, adding in teachers and finally parents.
Introduction
Polya (1945) Math in the making
Freudenthal (1973) Math as a human activity
Brown & Walter (1983) What-if-not
Kilpatrick (1987) MPP as goal and as means
MPP Activity
MPP still needs attention
MPP refers to different activities and its multi-facet nature draws attention to researchers and practitioners internationally (Silver, 1994; Silver, 2013, Singer, Ellerton, Cai, 2015, English, 2020).
However, it still need attention for learning, teaching and parenting.
Implementation (Ask what happen, which strategies can meet challenges, and why document designated outcomes) aims to empower involving participants for growth.
Growth in knowledge
To constitute growth in knowledge one must be curious.
When curious raises questions (pose) and finds answers (solve).
After answers ask more questions.
This cycle goes on and on
Pose and answer questions in or
擬題、佈題、命題
擬 題 : Constructing a new problem (Brown and Walter, 1983).
佈題: Presenting a problem properly (Butts, 1980).
命 題 : Designing items for examination (Leung, 2006).
Three translations
Problem Posing(擬題)
Today, the first (擬題) is my major focus
MPP means the formation of a mathematics problem which invites a solution from an intended problem solver who cares to solve it
By WHOM and FOR WHAT PURPOSE Silver, 2013,ESM Special Issue
Problem Posing and Solving
Posing (擬題) is important, related to (yet different from) problem solving (Leung, 2009)
Students’ Learning
Myself (and team) covered different independent variables and dependent variables (Kilpatrick, 1978).
Independent variables: tasks, subjects, situation
Dependent variable: products vs processes;
attitude, beliefs, creativity…etc.
Most frequentiy addressed: tasks
Variables in research
Posing a story vs posing math structure to match a text.
Content Specific vs Free Posing
Content: Number, Algebra, Geometry, Statistics
Posing a goal led to completion of posing with several givens (see Leung, 2013, 6 types)
In fact, one cannot tell what problem posing is until

My first piece, Leung, 1993
Task (X1): Test of Arithmetic Problem Posing (TAPP Version A: with numerical information content NIC, Version B: without NIC). Pose as many problems as you can from a description given in a text.
Subject (X2): Math Knowledge H/L
Subject (X3): Creative Thinking H/L
Posing Performance (Y): TAPP scores as
Leung & Silver (1997)
1.TAPP effectively evaluated arithmetic problem posing
2-1. Problem-posing performance was significantly better when task contained NIC
2-2. Problem-posing performance significantly related to math knowledge
2-3. Problem-posing performance NOT significantly related to creative thinking.
Results on Variables
(X1, X2, X3, Y)
Leung (1994)
MPP Process: a sequence of problems
After solving, subject used goal to prior posed problem as a given to pose more problem(s).
A replication: extended TAPP to TGPP
Addresse relationships between creative thinking and problem posing and problem-posing tasks in mathematics domains.
Fluency is general in verbal creativity problem posing flexibility is specific in problem posing.
A general, rather than specific, problem posing competence exists in children and can be measured by the test TGPP.
Leung 1997, ZDM
“ What problems should I pose? ”
“ Can you give me examples? ”
“ Is her posed problem better than mine? ”
“ Who is going to solve it? “
“ What if I myself cannot find the answer? “
“ How difficuit? ”
Strategies Needed: how to teach MPP?
Children’s first posing
Reflections on failure
When children did not perform well, teach them MPP (Leung, 2009) and show how to perform well.
We did content specific MPP research and concluded that children CAN performed well only with conditions.
Provide a variety of rich MPP tasks to children
Discuss children’s intended or unexpected outcomes
TRY: teach MPP myself, a math teacher education (MTE)
Attempt of a MTE
An action researcher who works with teachers;
teach teachers in ways she proposes them to teach (e.g. Math Problem Posing, MPP)
When Where Grade MPP Task Teachers
2001 Hong Kong 5 5x=40 PDGE primary 2009 Kaohsiung 7 Simultaneous Equations In-service middle 2014 Hualin 10 Sine Rule In-service high
5x=40
Grade 5
5X=40
Grade 7
Grade 10
Research on students’ learning MPP.
MTE try first
Children get used to it gradually
Use multiple tasks to stimulate children
Intended vs unxepected outcomes
Not to be frustrated, work with teachers
What I learn …
Teachers’ Growth
Problem posing is explicitly mentioned in the part concerning getting students to do inquiry. (Ministry of Education, Taiwan R.O.C., 2008).
Problem posing can be found in the curriculum guidebook for mathematics. (MOE of Taiwan, 2014)
Curriculum Standards revisited
Why content-wise?
Addition and Subtraction; Multiplication and Division;
Fractions, Decimals
Ratio and Rate, Probability and other topics. (For details, see http)
No need to ask for extra instructional time.
Teacher understood children’s learning when compared to posing freely
Inservice Teachers
Research on Tasks and on Children’s work
Content related MPP tasks (n=52)
By strands, by grade, and in six type of posing (unstated goal, Leung 2013)
Showed teachers how to deal with the 5 categories of children’s work (Leung 1997).
Used them in teaching.
Teachers joined MTE
If I introduce MPP
A new teaching idea to school teachers…
I must teach MPP myself
Leung & Wu (1999): Two real classroom examples.
FIX the ill-posed problems as that it can be solved
Ratio: Wu as teacher
Geometry: Leung as teacher
Leung & Wu (1999):
Would you try it (ever)?
If you introduce a new book to student…
If you introducing a new car to your customer…
If you feed a baby new food…
Do not introduce unless you try and find it great
Conducted study on MPP during student teaching, received grant (from NCS student research grants, See Leung 2011)
A course on MPS and MPP (18 weeks, selective)
Assignments on analyzing children’s posed problems to the 52 MPP tasks (mid-term, Teaching Methods).
Preservice Teachers

Educator Shared Teachers Knowledge
Jaworski (2008)
Be Active: Work with Teachers
Did not say “ I teach teachers “
Leung (2013) Educational Studies in Mathematics.
Level One: Teachers assist in developing task by data collection. [Helpers; I only].
Level Two: Teachers decide on when to use which tasks, use coding scheme then suggest how to revise task and coding. They also suggest ways to use children’s work in teaching. [Junior partners; II, III only].
Intervention Program
Teachers as participants
Year 1 Year 2 Year 3
MPP tasks across grades
Tasks in six types (Leung, 2013)
an algorithm,
text,
a figure/table,
a math topic,
an answer,
or a math problem.
Three sessions were conducted on
the first three Wednesdays of the term with 20
teachers each from the lower (grade 1-2), middle (grade 3-4), and upper grades (grade 5-6).
1. They did problem posing themselves.
2. They analyzed posed problems.
Pose and Analyze workshops
They experienced MPP in pairs as children while I was their “elementary school teacher”.
These “elementary school children” posed problems, and when they asked questions I showed how to answer these questions.
Frequently asked questions were recorded to compare with questions asked by children during
Did MPP themselves
The temperature of the cup of tea is 50℃. NOT-A- PROBLEM
Is there soup or tea in this cup? NON-MATH
The temperature of the cup is 45℃; the volume is 450 cc., how many altogether? IMPLAUSIBLE
The temperature of the cup of tea is 50℃, it is cooled down in 2 hours, what is the final temperature? INSUFFICIENT
If the cup of tea is 49℃ and heated to 5 degrees warmer, what is the final temperature?
SUFFICIENT
Analyze responses
Teachers’ questionnaires (TQ)
What type of tasks will teachers consider in MPP?
What types of problems are posed by children? Can teachers categorize them?
What are the successes and difficulties of teachers during implementation?
After half a year…..
I consider why and how teachers enact research- based tasks,
how teachers use the coding scheme to analyze children’s posed problems,
and the techniques, challenges and strategies they employed in enacting MPP.
What I learned after
Tasks Enactment: How
I did not give an example but said, “No, no. Try
to think it over. If I give you an example, you will pose a problem similar to my example!”
During the categorization exercise, the teachers were amazed to see real examples of children’s problems in the five different categories.
At times, they called “Can I use grade five tasks for
MTE shared knowledge on the coding method.
Teachers asked me to clarify the distinction between the Not a Problem and Non Math categories as well as the distinction between Impossible and Insufficient.
Analyze children’s work
Teachers’ sheared strategies on coding children’s work. “Hard to tell which is insufficient and which is implausible…so… I put them into 2 categories: Ok, not Ok”
Name names: who did try problem posing in teaching, and research on tasks development and enactment. Newsletter by month.
Building on the findings of this study, 3 teachers from this 60 did action research (Leung 2016) conditions that allow students to perform well on MPP.

What I learn: a never
ending cycle…
Parental Involvement
Why Parents’
Posing at home through diary writing (Leung & Wu, 2000)
Practical, connect to daily life
Make math learning continuous
Promote teacher-child-parent relationship
I teach in my sons’ classes (1-6)
I conducted parents workshops (K-6) over time
Parenting,
Communicating,
Volunteering,
Learning at home,
Decision making,
Collaborating with community.
MPP attends to communicating and learning at home.
Epstein, 2000
Parental involvement assisted young children to perform MPP that extended the activity from school to home, using strategies like reading picture books or diary writing (Leung, 2019).
Long term project in an-elementary school with walking distance from my school.
Parental involvement:
An Intervention (K-6)
Grade 3 and Grade 4
Parents as Teachers: They made up problems for children to solve.
Teacher educator took photographs for parents to consider.
Parents (in pairs) made up problems for peer to review and revise.
Teacher educator collated problems and organized Family Math Trail.
Building a math trial
Parents’ posing: Grade3, 4
Map with 10 checkpoints
Example Tasks

Grade 6
Leung & Kuo (2011)
Grade 4, MPP at home and in school
What are the changes in children’s mathematics problem posing after in-class instructions in mathematical problem posing?
What are the changes in children’s mathematics attitudes after in-class instructions in mathematical problem posing?
What are the changes in interaction of parent and child after in-class instructions in mathematical problem posing and practicing problem posing at home?
Data Collection
Problem posing instruction materials
parent-child posing sheet
mathematics attitude measure
students interview
parents interview
teachers’ journal video tapes
Data coding of posed problems
by Leung & Silver (1997).
Parents’ views on problem posing
They expressed that normally they read quickly and signed children’s record book.
They discussed more with their children and became to understand children’s thoughts.
A long time since I was in elementary school and there are new ways to do math now.
I learn more on how to supervise the homework after this problem posing exercise.
Children’s views on posing 1/2
Three of them normally did homework with mothers, one with father, one with elder sister and the last one with grand parent.
“I do homework by myself at home”
“Dad and Mom are busy, they sign without reading my work”
After introducing problem posing at home:
“ We spend more time doing homework together, at least 10 to 30 minutes more: “
Leung & Kuo (2011)
MPP of children improved over time.(PP, attitude)
MPP at home increased interactions of family members.
MPP at home increased parents’ awareness of child’s learning in school
Problem posing in-class and at home can enhance interactions of parents, children and teacher.
Views from parents and children are positive towards problem posing instruction and problem posing at home.
What I learn from parents
Conclusion
The investigator is an action researcher herself
Found that children and prospective teachers were inexperienced in problem posing.
Developed tasks and systematic assessment.
Offered a two-credit course for prospective teachers.
One student received award funding from the National Science Council (Leung, 2001).
Teacher-training workshops for in-service teachers.
Intervention program for parents (K-6).
