2 Key Messages in Problem- solving Problem solving is mul1- dimensional and can be viewed as Problem- solving Skill Content Methodology 2

3 Overview of Problem- solving Sessions Session One Theory & Prac>ce of Problem- solving Session Two Problem- solving Support Materials, ICT, Assessment & Differen>a>on Session Three Reflec>ve Prac>ce - Suppor>ng Teaching and Learning 3

4 Objec>ves Session One To contextualise problem- solving To introduce an instruc>onal framework for problem- solving To explore mathema>cal language, oral and mental math in problem- solving 4

5 What is Problem- solving? How would you define Problem- solving? Flipchart Ac>vity* 5

6 Problem- solving is.....the ability to analyse mathema0cal situa0ons; to plan, monitor and evaluate solu0ons; to apply strategies; and to demonstrate crea0vity and self- reliance in using mathema0cs (PSMC: p.8) 6

7 What is Numeracy? Numeracy encompasses the ability to use mathematical understanding and skills to solve problems and meet the demands of day-to-day living in complex social settings. (Literacy & Numeracy Strategy: p.8) 7

8 Na0onal & Interna0onal Perspec0ve Ensure that the curriculum contains addi>onal guidance for teachers on approaches to teaching and learning advocated in areas such as es>ma>on, shape and space, measures, the use of co- opera>ve group learning and problem- solving approaches Literacy & Numeracy Strategy (2011: 56) Irish pupils displayed rela>ve strengths on number and knowing and rela>ve weaknesses on geometric shapes and measures, data display and reasoning (PIRLS & TIMSS: 2011) 8

9 Problem- solving as a Skill of the Curriculum Applying & Problem- Solving Understanding & Recalling Communica>ng & Expressing Implemen>ng Integra>ng & Connec>ng Reasoning (PSMC:1999: 68) Class Groups Ac>vity* 9

10 Problem- solving as Content Within the Mathema0cs Curriculum Junior & Senior Infants Shape & Space (2D Shape) Solve problems involving shape and space First & Second Class Shape & Space (2D/3D Shape) solve and complete prac>cal tasks and problems involving 2- D and 3- D shapes The child should be enabled to Third & Fourth Class Measures (Length) Solve and complete prac>cal tasks and problems involving the addi>on, subtrac>on,mul>plica>on and simple division of units of length (m, cm, km). FiJh & Sixth Class Data (RepresenMng & InterpreMng Data) Use data sets to solve problems - Solve problems based on data sets and representa>ons used in class - what were the most popular buns at a cake sale? 10

11 Problem- solving as Content Within the Wider Curriculum SPHE Make decisions, solve problems and take appropriate ac>ons in various personal, social and health contexts SESE Develop a scien>fic approach to problem- solving which emphasises understanding and construc>ve thinking Children will be enabled to: Visual Arts Solve problems crea>vely through imagina>ve thinking and so encourage individuality and enterprise Physical Educa1on Be inven>ve, make decisions, solve problems and develop autonomy through movement ac>vi>es 11

12 Key Methodologies of PSMC Problem Solving An Overarching Methodology Talk & Discussion Ac>ve Learning / Guided Discussion Collabora>ve / Co- opera>ve Learning Use of the Environment Skills Through Content Strong emphasis should be based on developing the ability to ques>on, to analyse, to inves>gate, to think cri>cally and to interact effec>vely with others to solve problems (PSMC: 1999: 19) 12

13 Problem- solving and Co- opera0ve Learning It is more likely that children will develop a sense of ownership over what they have learned and be able to transfer it to different situa>ons when they have been acmvely involved in the learning process. While independent learning is fostered, it is equally essen>al that children are given opportuni>es to interact with others and with their environment and to learn to co- operate with their peers. The role of the teacher will be central to the use of effec>ve ac>ve learning and teaching techniques in the classroom. He/she will need to structure acmvimes and guide and direct the work in such a way that a child can parmcipate in a real and meaningful way and can develop a sense of responsibility for his/her own learning. (SPHE Curriculum 1999, p.6). 13

14 Problem- solving The Key Ques1on What are the most common difficul>es your pupils encounter whilst engaged in problem- solving exercises? 14

15 Problem- solving DifficulMes Classroom Experiences Reading the problem with understanding Selecting the relevant information Using the necessary mathematical expression Seeing relationships and using patterns Using existing mathematical knowledge / language Developing a systematic / strategic approach Making the required calculation correctly 15

16 Reflec0on - Our Classroom Culture When a teacher succeeds in sekng up a classroom in which students feel obligated to listen to one another, to make their own contribu1ons clear and comprehensible, and to provide evidence of their claims, that teacher has set in place a powerful context for student learning (Chaplain, O Connor & Anderson, 2009) Diamond Nine Ac>vity* 16

18 Asking ques>ons such as... How did you get that? Estimate Could it be done another way? Compare Put into your own words How does that connect with? Describe 18

21 Development of Mathema1cal Language Many children fail at mathema0cs because their mathema1cal vocabulary is insufficient to cope with the terminology of problems. Development of the necessary vocabulary in a consistent manner throughout the classes must be stressed (PSMC :Teacher Guidelines: p.36) 21
