Unit 2.1 Developmental progression in the learning of mathematical concepts Dr. Priya Mathew St. Joseph's College of Education, Mysore 5/2/2016 1 Jean Piaget : Cognitive Theory • Laid foundation for Cognitive Psychology • Focus not only on the external behaviour of the learner, rather importance is given to internal behaviour of the learner • Our thinking process change radically, though slowly, from birth to maturity because we constantly strive to make sense of the world. • Believed that learning is a function of certain process • They are, organization, adaptation, equilibration, and operation 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 2 1. Organization • Intelligence was not random, but as set of organised cognitive structures • People are born with a tendency to organize their thinking processes into psychological structures • These psychological structures are our systems for understanding and interacting with the world • These structures are called schema – mental systems or categories of perception and experience 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 3 Organization………………. • A schema is a concept or framework that exists in an i di idual’s mind to organise and interpret information • Schema can range from simple to complex • Schemas are the basis building blocks of thinking • Eg. Different voices from environment, sucking through straw • Organization is the ongoing process of arranging information and experience into mental system or categories (schemas) 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 4 2. Adaptation • the adjustment to a new environment is adaptation • People inherit the tendency to adapt to their environment • Two basic process are involved in adaptation: a) Assimilation b) Accommodation 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 5 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 6 a) Assimilation • Fitting the new information into existing schemas. • It is a process of incorporating new objects and experiences into the existing schemas. • It is applied to every new object and in every new situation • It is trying to understand something new by fitting it into what we already know. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 7 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 8 b) Accommodation • Altering existing schemas or creating new ones in response to new information • It occurs when a person must change existing schemas to respond to a new situation. • If data cannot be made fit any existing schemas, then more appropriate structures must be developed. • It is the modification of the individuals internal cognitive structures. • Accommodation accompanies assimilation • Here the child remains active, and explores, questions, experiments, etc. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 9 Adaptation …………………… • People adapt their environments by using existing schemas whenever these schemas work (assimilation) and by modifying and adding to their schemas when something new is needed (Accommodation) • By assimilating new to the old and by accommodating the old to the new, the person learns. • This process of adaptation continues thought life. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 10 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 11 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 12 4. Operation • A mental activity that transforms or manipulates • eg. Adding, multiplying etc. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 13 3. Equilibration The act of searching for a balance It is the search for mental balance between cognitive schemas and information from the environment If we apply a particular schema to an event or situation and the schemas works, then the equilibrium exists. If the scheme does not produce a satisfying result, then disequilibrium starts and we become uncomfortable. This motives us to keep searching for solution through assimilation and accommodation and thus our thinking changes and moves ahead. Dr. Priya Mathew St. Joseph's College of Education, Mysore 5/2/2016 14 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 15 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 16 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 17 Object permanence is the understanding that objects continue to exist even when they cannot be observed (seen, heard, touched, smelled or sensed in any way). 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 18 Sensorimotor stage • The hild’s thi ki g i ol es seei g, o i g, touching, tasting, etc. • Develops object permanence • Begins to make use of imitation, memory and thought • Begins to recognize that objects do not cease to exist when they are hidden • Moves from reflex actions to goal directed activity. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 19 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 20 • • • • • Learning Mathematics at sensorimotor Stage They have the ability to link numbers to objects (one dog, two cats, three toys). To develop mathematical capability of a child in this stage, the hild’s ability might be enhanced. At this stage they have some understanding of the concept of numbers and counting. We should provide solid mathematical foundation by providing activities that incorporate counting It enhances hildre ’s conceptual development of number. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 21 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 22 Do not understand the concept of conservation, the principle that quantity remains the same even we change the shape 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 23 Pre-operational Stage • Children has not mastered mental operation but moving towards mastery • Ability to use symbols, words, gestures, signs, images, etc. • difficulty with reversible thinking (thinking backward) • Difficulty with conservation (the principle that some characteristics of an object remain the same despite changes in appearance) • Children face difficulty in considering more than one aspect at a time, i.e. decentring, 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 24 • They lack basic logical operational skills. • Pre-operational children are egocentric They think the world is created for them I a ility to see the orld through other’s perspective Should be gone by age 5 • They indulge in collective monologue • Animism- belief that inanimate things are alive. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 25 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 26 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 27 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 28 Learning Mathematics at preoperational stage • Child links together unrelated events, see objects as possessing life. • Does not understand another point of view and cannot reverse operations • For eg. A child at this stage who understands that adding 2 to 5 yields seven . But the reverse operation of taking two from seven is not possible. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 29 Learning Mathematics at preoperational stage • Child should engage with problem-solving tasks that incorporate available materials such as blocks, sand, and water. • While the child is working with a problem, the teacher should elicit conversation from the child. • The verbalization of the child, as well as his actions on the materials gives a basis that permits the teacher to infer the mechanisms of the hild’s mental thought process. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 30 Learning Mathematics at preoperational stage • Childre ’s perceptions are generally restricted to one aspect or dimension of an object. • Eg. Concept of conservation. The child use only one dimension, height as the basis for the judgment of another dimension, volume. • Teachers should employ effective questioning about characterizing objects. • For eg. A teacher could ask students to group the shapes according to similar characteristics. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 31 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 32 •Concrete operational stage • Children at primary level • Understand the concept of conservation • Can think logically, use analogies, and perform mathematical transformation (5+9 is the same as 9+5) • Is also know as reversibility which promotes logical thinking • Abstract thinking is not possible 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 33 Learning Mathematics at Concrete Operational Stage • Characterized by Seven types of conservation : Number, Length, liquid, Mass, Weight, area, volume. • Conservation of number is mastered by age 6 • Conservation of length and weight is mastered by age 8 or 9. • Perform operations like identity: if something is added or taken away the material remains same 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 34 Learning Mathematics at Concrete Operational Stage • Develop transitivity • Eg. if A is bigger than B, and B is bigger than C then what is the relation between A & C? • The major change of this period is that the development proceeds from pre-logical thought to logical solutions and concrete problems. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 35 Learning Mathematics at Concrete Operational Stage • They can consider two or three dimensions simultaneously (Decentration) • For eg. In the liquid experiment, if the child notices the lowered level of the liquid, he also notices the dish is wider , seeing both the dimensions at the same time. • Seriation and classification are the two logical operations that develop during this stage – both are essential for understanding the number concept. • Seriation= it is the ability to order objects according to increasing or decreasing length, weight, or volume. • Classification = grouping objects on the basis of common characteristics 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 36 Learning Mathematics at Concrete Operational Stage • Hands-on experiences and multiple ways of representing a mathematical solution can be the ways of fostering development of this stage. • The importance of hands-on experience cannot be over emphasized at this stage. • These activities helps the students to make abstract ideas concrete. • Hands-on mathematical ideas and concepts are useful for solving problems. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 37 Learning Mathematics at Concrete Operational Stage • Concrete experiences are needed to explore concepts such as place values and arithmetic operations. • Materials like: pattern blocks, cubes, tiles, geoboards, tangrams, dice, etc…. • Teachers can use convenient materials in activities such as paper folding and cutting • Through the use of these materials students acquire experience that help to lay foundation for advanced mathematical thinking. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 38 Learning Mathematics at Concrete Operational Stage • Teachers should help the students to make connections between the mathematical concepts and the activity. • Children may not automatically make connections between the work they do with manipulative materials and the corresponding abstract mathematics. • Children tend to think that the manipulations they do with models are one method for finding a solution and pencil- and paper math is entirely separate. Dr. Priya Mathew St. Joseph's College of 5/2/2016 39 Education, Mysore Learning Mathematics at Concrete Operational Stage • For eg. • How a four by six inch rectangle built with wooden tiles relates to 4 multiplied by 6 or four groups of six? • Teacher could help students make connections by showing how the rectangles can be separated into four rows of six tiles each and by demonstrating how rectangle is another representation of four groups of six. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 40 Learning Mathematics at Concrete Operational Stage • Creating opportunities for students to present mathematical solutions by multiple ways (eg. Symbol, graphs, tables) is one tool for cognitive development in this stage. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 41 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 42 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 43 Formal Operational Stage • • • • • • • • Thought process becomes quite systematic Mental manipulation- number of variables Imagination develops Develop experimental spirit Grater abstraction and metacognition Ability to judge truth of logical relationships Reflective thinking Debate – for and against a topic 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 44 Learning Mathematics at Formal Operational Stage • The child is capable of forming hypotheses and deducing possible consequences • Can allow the child to construct his own Mathematics • Child begins to develop abstract thought patterns; here reasoning is executed using pure symbols without the necessity of observant (perceptive) data • For eg. The learner can solve x+3x = 12 without having to refer to a concrete situation like “ Geetha has two chocolates and her friend has thrice as many. Together they have 12. So how many chocolates Geetha Dr. Priya Mathew St. Joseph's College of 5/2/2016 45 has?’ Education, Mysore Learning Mathematics at Formal Operational Stage • Reasoning skills in this stage include: clarification, inference, evaluation and application 1. Clarification: It requires students to identify and analyse elements of a problem, allowing them to interpret the information needed in solving a problem. Teachers can help students enhance their mathematical understanding by encouraging students to take out relevant information from a problem statement 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 46 Learning Mathematics at Formal Operational Stage 2. Inference : students at this stage are developmentally ready to make inductive and deductive inferences in mathematics 3. Evaluation : Evaluation involves using criteria to judge the adequacy of the problem 4. Application : Students connecting mathematical concepts to real-life situation 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 47 Learning Mathematics at Formal Operational Stage • The teacher can provide critical direction by emphasizing methods of reasoning • Thus the child can discover concepts through investigation. • While the teacher studies the hild’s work to better understand his thinking , the child should be encouraged to self- check, approximate, reflect and reason 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 48 Learning Mathematics at Formal Operational Stage • All students in a class are not necessarily operating at the same level. • Teacher should try to find out their students cognitive levels to adjust their teaching accordingly. • In general, the knowledge of Piaget’s stages helps the teacher understand the cognitive development of the child as the teacher plans stage appropriate activities to keep studnets active. 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 49 5/2/2016 Dr. Priya Mathew St. Joseph's College of Education, Mysore 50
