- 1. THE DEVELOPMENT OF TEACHING AND LEARNING MATHEMATICS GLOBALLY AND LOCALLY Theories and Principles Servino, Edel A. Bron, Irene B. Delatado, Mary Joy Ibo, Jessica Penero, Mary Jonabelle Villareal, Antonette
- 2. Mathematics Education - In contemporary education, mathematics education is the practice of teaching and learning mathematics, along with the associated scholarly research. - Researchers in mathematics education are primarily concerned with the tools, methods and approaches that facilitate practice or the study of practice.History - Elementary mathematics was part of the education system in most ancient civilisations, including Ancient Greece, the Roman empire, Vedic society and ancient Egypt. In most cases, a formal education was only available to male children with a sufficiently high status, wealth or caste. - In Platos division of the liberal arts into the trivium and the quadrivium, the quadrivium included the mathematical fields of arithmetic and geometry. - The first mathematics textbooks to be written in English and French were published by Robert Recorde, beginning with The Grounde of Artes in 1540. - In the Renaissance, the academic status of mathematics declined, because it was strongly associated with trade and commerce. - This trend was somewhat reversed in the seventeenth century, with the University of Aberdeen creating a Mathematics Chair in 1613, followed by the Chair in Geometry being set up in University of Oxford in 1619 and the Lucasian Chair of Mathematics being established by the University of Cambridge in 1662. - In the 18th and 19th centuries, the industrial revolution led to an enormous increase in urban populations. Basic numeracy skills, such as the ability to tell the time, count money and carry out simple arithmetic, became essential in this new urban lifestyle. - By the twentieth century, mathematics was part of the core curriculum in all developed countries.ObjectivesAt different times and in different cultures and countries, mathematics education has attemptedto achieve a variety of different objectives. These objectives have included: • The teaching of basic numeracy skills to all pupils • The teaching of practical mathematics (arithmetic, elementary algebra, plane and solid geometry, trigonometry) to most pupils, to equip them to follow a trade or craft • The teaching of abstract mathematical concepts (such as set and function) at an early age • The teaching of selected areas of mathematics (such as Euclidean geometry) as an example of an axiomatic system and a model of deductive reasoning
- 3. • The teaching of selected areas of mathematics (such as calculus) as an example of the intellectual achievements of the modern world • The teaching of advanced mathematics to those pupils who wish to follow a career in Science, Technology, Engineering, and Mathematics (STEM) fields. • The teaching of heuristics and other problem-solving strategies to solve non-routine problems.Methods • Conventional approach - the gradual and systematic guiding through the hierarchy of mathematical notions, ideas and techniques. Starts with arithmetic and is followed by Euclidean geometry and elementary algebra taught concurrently. • Classical education - the teaching of mathematics within the quadrivium, part of the classical education curriculum of the Middle Ages, which was typically based on Euclids Elements taught as a paradigm of deductive reasoning. • Rote learning - the teaching of mathematical results, definitions and concepts by repetition and memorization typically without meaning or supported by mathematical reasoning. A derisory term is drill and kill. In traditional education, rote learning is used to teach multiplication tables, definitions, formulas, and other aspects of mathematics. • Exercises - the reinforcement of mathematical skills by completing large numbers of exercises of a similar type, such as adding vulgar fractions or solving quadratic equations. • Problem solving - the cultivation of mathematical ingenuity, creativity and heuristic thinking by setting students open-ended, unusual, and sometimes unsolved problems. Problem solving is used as a means to build new mathematical knowledge, typically by building on students prior understandings. • New Math - a method of teaching mathematics which focuses on abstract concepts such as set theory, functions and bases other than ten. • Historical method - teaching the development of mathematics within an historical, social and cultural context. Provides more human interest than the conventional approach. • Standards-based mathematics - a vision for pre-college mathematics education in the
- 4. US and Canada, focused on deepening student understanding of mathematical ideas and procedures, and formalized by the National Council of Teachers of Mathematics which created the Principles and Standards for School Mathematics. 1. Transfer of Learning - Transfer of learning deals with transferring ones knowledge and skills from one problem- solving situation to another. You need to know about transfer of learning in order to help increase the transfer of learning that you and your students achieve. - For example, suppose that when you were a child and learning to tie your shoes, all of your shoes had brown, cotton shoelaces. You mastered tying brown, cotton shoelaces. Then you got new shoes. The new shoes were a little bigger, and they had white, nylon shoe laces. The chances are that you had no trouble in transferring your shoe-tying skills to the new larger shoes with the different shoelaces.Near Transfer - A nearly similar problem or task is automatically solved with little or no conscious thought.In recent years, Salomon & Perkins (1988) developed the low-road/high-road theory on transferof learning and proven to be a more fruitful theory.Low-road transfer - refers to developing some knowledge/skill to a high level of automaticity. It usually requires a great deal of practice in varying settings. Shoe tying, keyboarding, steering a car, and single-digit arithmetic facts are examples of areas in which such automaticity can be achieved and is quite useful.High-road transfer - involves: cognitive understanding; purposeful and conscious analysis; mindfulness; and application of strategies that cut across disciplines. - In high-road transfer, there is deliberate mindful abstraction of an idea that can transfer, and then conscious and deliberate application of the idea when faced by a problem where the idea may be useful. 2. General Learning TheoryBenjamin Bloom- is probably best known for his 1956 "taxonomy."- he also did seminal work on student learning through different methods such as tutoring, peer

Situated Learning “To Situate”- means to involve other learners, the environment, and the activities to create meaningSituated Learning- Learning is a function of the activity, context and culture in which it occurs.- Knowledge and skills are learned in the contexts that reflect how knowledge is obtained andapplied in everyday situations.- A means for relating subject matter to the needs and concerns of learners.- Learning is essentially a matter of creating meaning from the real activities of daily living. Social interaction - Critical component of situated learning. - Learners become involved in a “community of practice” which embodies certain beliefs and behaviors to be acquired.Four Major Premises Guiding the Development of Classroom Activities (Anderson, Rederand Simon, 1996)1. Learning is grounded in the actions of everyday situations;2. Knowledge is acquired situationally and transfers only to similar situations;3. Learning is the result of a social process, encompassing ways of thinking, perceiving, problemsolving and interacting in addition to declarative and procedural knowledge; and4. Learning is not separated from the world of action but exists in robust, complex, socialenvironment made up of actors, actions and situations.Situated learning uses cooperative and participative teaching methods as the means of acquiringknowledge.Knowledge is obtained by the processes described (Lave, 1997) as Way In and Practice. Way in – a period of observation in which a learner watches a master and makes a first attempt at solving a problem. Practice- is refining and perfecting the use of acquired knowledge.
- 7. 4. Constructivism Constructivism - Programs aim to have students construct their own knowledge through their own process of reasoning. Teachers - Pose their problems and encourage students to think deeply about possible solutions. - Promote making connections to other ideas within mathematics and other disciplines. - Ask students to furnish proof/ explanations for their work. - Use different representations of mathematical ideas to foster students’ greater understanding. Students Are expected to: - Solve problems - Apply mathematics to real-world situations; and - Expand on what they already knowConstructivist approach to thinking about mathematics education. 1. People are born with innate ability to deal with small integers and to make comparative estimates of larger numbers. 2. The human brain has components that can adapt to learning and using mathematics. 3. Humans vary considerably in their innate mathematical abilities or intelligence. 4. The mathematical environments that children grow up vary tremendously. 5. thus, when we combine nature and nurture, by the time children enter kindergarten, they have tremendously varying levels of mathematical knowledge, skills, and interests. 6. Even though we offer a somewhat standardized curriculum to young students, that actual curriculum, instruction, assessment, engagement of intrinsic and extrinsic motivation, and so on varies considerably. 7. thus, there are huge differences among the mathematical knowledge and skill levels of students at any particular grade level or in any particular math course 8. thus, mathematics curriculum, instruction, and assessment needs to appropriately take into consideration these differences. Educational Trends: 1. The transition of the teachers’ role from “sage on the stage” to “guide on the side” 2. Teaching “higher order” skills such as problem-solving, reasoning, and reflection 3. Enabling learners to learn how to learn; 4. More open-ended evaluation of learning outcomes; 5. And, of course, cooperative and collaborative learning skills
- 8. 5. Cooperative Learning • is an approach to organizing classroom activities into academic and social learning experiences. Students must work in groups to complete tasks collectively.5 ElementsPositive interdependence • Students must fully participate and put forth effort within their group • Each group member has a task/role/responsibility therefore must believe that they are responsible for their learning and that of their groupFace-to-Face Promotive Interaction • Each group member has a task/role/responsibility therefore must believe that they are responsible for their learning and that of their group • Students explain to one another what they have or are learning and assist one another with understanding and completion of assignmentsIndividual Accountability • Each student must demonstrate master of the content being studied • Each student is accountable for their learning and work, therefore eliminating “social loafing”Social Skills • Social skills that must be taught in order for successful cooperative learning to occur • Skills include effective communication, interpersonal and group skills – Leadership – Decision-making – Trust-building – Communication – Conflict-management skillsGroup Processing • Every so often groups must assess their effectiveness and decide how it can be improvedChallenges • Need to prepare extra materials for class use • Fear of the loss of content coverage • Do not trusts students to acquire knowledge by themselves • Lacks of familiarity with cooperative learning methods • Students lack the skills to work in group

He also invented an airplane engine that ran on alcohol and contributed to new designs of producing solar energy. Contributions of Mathematics Educators The following are some of the people who have had a significant influence on theteaching of mathematics at various periods in history.1. Euclid of Alexandria - was a Greek mathematician, often referred to as the "Father of Geometry". He was active in Alexandria during the reign of Ptolemy I (323–283 BC).
- 13. - author of The Elements Elements is one of his most influential works in the history of mathematics, serving as the main textbook for teaching mathematics (especially geometry) from the t ime of its publication until the late 19th or early 20th century. In the Elements, Euclid deduced the principles of what is now called Euclidean geometry from a small set of axioms. - Euclid also wrote works onperspective, conic sections, spherical geometry, number theory and rigor.Other worksIn addition to the Elements, at least five works of Euclid have survived to the present day. Theyfollow the same logical structure as Elements, with definitions and proved propositions.• Data deals with the nature and implications of "given" information in geometricalproblems; the subject matter is closely related to the first four books of the Elements. • On Divisions of Figures, which survives only partially in Arabic translation, concerns the division of geometrical figures into two or more equal parts or into parts in given ratios. It is similar to a third century AD work by Heron of Alexandria. • Catoptrics, which concerns the mathematical theory of mirrors, particularly the images formed in plane and spherical concave mirrors. • Phaenomena, a treatise on spherical astronomy, survives in Greek; it is quite similar to On the Moving Sphere by Autolycus of Pitane, who flourished around 310 BC.• Optics is the earliest surviving Greek treatise on perspective.In its definitions Euclid follows the Platonic tradition that vision is caused by discrete rays whichemanate from the eye.Other works are credibly attributed to Euclid, but have been lost. • Conics was a work on conic sections that was later extended by Apollonius of Perga into his famous work on the subject. • Porisms might have been an outgrowth of Euclids work with conic sections, but the exact meaning of the title is controversial.
- 14. • Pseudaria, or Book of Fallacies, was an elementary text about errors in reasoning. • Surface Loci concerned either loci (sets of points) on surfaces or loci which were themselves surfaces; under the latter interpretation, it has been hypothesized that the work might have dealt with quadric surfaces. • Several works on mechanics are attributed to Euclid by Arabic sources.2. Tatyana Alexeyevna Afanasyeva - Dutch/Russian mathematician who advocated the use of visual aids and examples for introductory courses in geometry for high school students - Tatyana collaborated closely with her husband, most famously on their classic review of thestatistical mechanics of Boltzmann. She published many papers on various topics such asrandomness and entropy, and teaching geometry to children.3. Robert Lee Moore - was an American mathematician, known for his work in general topology and the Moore method of teaching university mathematics. - originator of the Moore method4. George Pólya - Hungarian mathematician, author of How to Solve It He was a professor of mathematics from 1914 to 1940 at ETH Zürich in Switzerland and from 1940 to 1953 at Stanford University carrying on as Stanford Professor Emeritus the rest of his life and career. - He worked on a great variety of mathematical topics, including series, number theory,mathematical analysis, geometry, algebra, combinatorics, and probability.5. Georges Cuisenaire - (1891–1976), Belgian primary school teacher who invented Cuisenaire rods6. Hans Freudenthal - was aDutch mathematician. He made substantial contributions to algebraic topology and also took an interest in literature, philosophy, history and mathematics education. - nFreudenthal focused on elementary mathematics education.
- 15. - In the 1970s, his single-handed intervention prevented the Netherlands from following the worldwide trend of "`new math". - He was also a fervent critic of one of the first international school achievement studies. - In 1971 he founded the IOWO at Utrecht University, which after his death was renamed Freudenthal Institute, the current Freudenthal institute for science and mathematics education.7. Toru Kumon - was a Japanese mathematics educator -In 1954, Kumon began to teach his oldest son, who was doing poorly in mathematics in primary school, and developed what later became known as the Kumon method. - This method involves repetition of key mathematics skills, such as addition, subtraction, multiplication, and division, until mastery is reached. Students then progress to studying the next mathematical topic. Kumon defined mastery as beingable to get an excellent score on the material in the time given, which is intended to benefitstudents in all their studies. Kumon strongly emphasised the concepts of time andaccuracy. - As a result of the method, other parents became interested in Kumons ideas, and in 1956, the first Kumon Center was opened in Osaka,Japan. - In 1958, Toru Kumon founded the Kumon Institute of Education, which set the standards for the Kumon Centers that began to open around the world. The Institute continues today to focus on individual study to help each student reach his or her full potential. The underlying belief behind the Kumon Method is that, given the right kind of materials and the right support, any child is capable of learning anything. At any time, there are more than 4 million Kumon students worldwide, and since 1956, more than 19 million students have enrolled in Kumon Centers worldwide.8. Pierre van Hiele and Dina van Hiele-Geldof, - Dutch educators (1930s - 1950s) who proposed a theory of how children learn geometry (1957), which eventually became very influential worldwide
- 16. - Van Hiele model is a theory that describes how students learn geometry. The theory originated in 1957 in the doctoral dissertations of Dina van Hiele-Geldof and Pierre van Hiele (wife and husband) at Utrecht University, in the Netherlands.9.Robert Parris Moses - is an American, Harvard-trained educator who was a leader in the 1960s Civil Rights Movement and later founded the nationwide U.S. Algebra project. - In 1982 he received a MacArthur Fellowship, and used the money to create the Algebra Project, a foundation devoted to improving minority education in math. Moses taught math for a time at Lanier High School in Jackson, Mississippi, and used the school as a laboratory schoolfor Algebra Project methods.10.Robert & Ellen Kaplan - (about 1930/40s-), authors of Nothing That Is, The Art of the Infinite: The Pleasures of Mathematics, and Chances Are: Adventures in Probability (by Michael Kaplan and Ellen Kaplan). Filipino Mathematics Teachers and Their ContributionThe following people all taught mathematics at some stage in their lives, although they are betterknown for other things:Charles Lutwidge Dodgson • was an English author, mathematician, logician, Anglican deacon and photographer.Mathematical Findings and WorkWithin the academic discipline of mathematics, Dodgson worked primarily in the fields ofgeometry, matrix algebra, mathematical logic and recreational mathematics, producingnearly a dozen books which he signed with his real name. Dodgson also developed new ideas inthe study of elections (e.g., Dodgsons method) and committees; some of this work was notpublished until well after his death. He worked as a mathematics tutor at Oxford, an occupationthat gave him some financial security.

Hehaslectured on mathematics and musical theater. Lehrer is best known for the pithy, humoroussongs that he recorded in the 1950s and 1960s.His work often parodies popular song forms, such as in "The Elements", where he sets the namesof the chemical elements to the tune of the "Major-Generals Song" from Gilbert andSullivans Pirates of Penzance. Lehrers earlier work typically dealt with non-topical subjectmatter and was noted for its black humor, seen in songs such as "Poisoning Pigeons in the Park".In the 1960s, he produced a number of songs dealing with social and political issues of the day,particularly when he wrote for the U.S. version of the television show That Was The Week ThatWas.Mathematical publicationsThe American Mathematical Society database lists Lehrer as co-author of two papers:

He is perhapsbest known for his trigonometric tables and as Nicolaus Copernicuss sole pupil. He facilitatedthe publication of his masters De revolutionibus orbium coelestium (On the Revolutions of theHeavenly Spheres).TrigonometryFor much of his life, Rheticus displayed a passion for the study of triangles, the branch ofmathematics now called trigonometry. In 1542 he had the trigonometric sections of CopernicusDe revolutiobis published separately under the title De lateribus et angulis triangulorum (On theSides and Angles of Triangles). In 1551 Rheticus produced a tract titled Canon of the Science ofTriangles, the first publication of six-function trigonometric tables (although the wordtrigonometry was not yet coined). This pamphlet was to be an introduction to Rheticus greatestwork, a full set of tables to be used in angular astronomical measurements.At his death, the Science of Triangles was still unfinished. However, paralleling his ownrelationship with Copernicus, Rheticus had acquired a student who devoted himself tocompleting his teachers work.Valentin Otto oversaw the hand computation of approximately100,000 ratios to at least ten decimal places. When completed in 1596, the volume,Opuspalatinum de triangulus, filled nearly 1,500 pages. Its tables were accurate enough to be used inastronomical computation into the early twentieth century.Works• Narratio prima de libris revolutionum Copernici(1540)

Using mathematics to tell stories and using stories to explain mathematics are two sides ofthe same coin. They join what should never have been separated: the scientists and the artistsways of uncovering truths about the world."(Frucht, xii)LITERATURE - It stirs our imaginations and emotions, making ideas more enjoyable and memorable. -It enlivens what many people see as the isolating abstractness of mathematics (cf. Midgley, 1-39). -It also elicits expressions of feeling, increasing our insight about joys and frustrations in studying math.Different way of using math in literatures(1) Call on math to illuminate a theory (e.g., Dostoyevsky, and Tolstoy, and Austen);(2) Be inspired by mathematical themes to create a work of art based on the themes (e.g., Doxiadis, Growney, Lem,Reese, and Upson);(3) Poke fun at typical experiences in learning math or at mathematicians (e.g., Dodgson,Leacock and Russell);(4) want to produce an educational work (e.g., Enzensberger); or(5) want to write theimagined life of an intriguing mathematician (e.g., Petsinis).Advantages of Literature in Teaching Mathematics Provide a context or model for an activity with mathematical content. Introduce manipulatives that will be used in varied ways (not necessarily as inthe story). Inspire a creative mathematics experience for children.

- 28. ORIGAMI Origami is a Japanese compound word which means “paper folding”. It is used todescribe craft made from folded paper in Japan as well as pieces originating in other regions,since so many people associate folded paper crafts with Japan in particular. Individual origamipieces can vary widely in size and design, from simple folded boxes to ornate creatures made byjoining several different sheets of paper. Many young people learn origami in school, and somepeople continue to practice this craft into adulthood. The art of paper folding actually originated in China around the first century CE. TheChinese referred to their folded paper crafts as zhe zhi, and monks brought the tradition withthem to Japan when they visited in the sixth century. The Japanese quickly took to paper foldingas a pastime, developing a number of traditional folds, shapes, and styles, many of which wereconsidered fortuitous for particular occasions or life events. The crane is a particularly famouslucky origami shape.Highlights in Origami History100 ADPaper-making originated in China by Tsai Lun, a servant of the Chinese emperor. The art of paper folding began shortly after.600 ADPaper-making spread to Japan where origami really took off.800-1100ADOrigami was introduced to the West (Spain) by the Moors who made geometric origami models.

Consult a doctor immediately if this occurs. This product contains magnets. Magnets sticking together or becoming attached to a metallic object inside the human body can cause serious or fatal injury. Seek immediate medical help if the magnets are swallowed or inhaled. The NeoCube or any of the spheres should never be put in the mouth, ears, nose, or any other bodily orifice. The strong magnets in the NeoCubeTM can damage or destroy some electronic devices. Therefore, it should never be put close to or directly in contact with electronic products. Strong magnets can even damage electronic medical devices. Therefore the NeoCubeTM should never be handled, used by, or brought near anyone with a pacemaker or other electronic medical device. Strong magnets can also damage or destroy information stored magnetically. Some examples of these are: credit card strips, floppy disks and hard disks. Therefore the NeoCubeTM should not be put close to or directly in contact with any type of magnetically stored data. Never attempt to burn the NeoCubeTM. If the metallic coating around the spheres breaks down, discontinue use. This is precautionary. The NdFeB material which is the magnetic material in the NeoCubeTM is a relatively new material, and long term effects of direct skin exposure are therefore unknown, although there have been no studies which indicate that it is in any way transdermally toxic. This product is not intended to treat, diagnose or cure any diseases. This product contains small balls..

This Foldable project is used to help teachers analyze data, sort the strengths and weaknesses of their students and determine the question levels from a TAKS-Released Test so that they can make informed decisions about instruction. Example of Foldables TYPES OF FOLDABLEo A POCKET BOOK FOLDABLE 1. Fold a piece of 8 ½” x 11” paper in half horizontally 2. Open the folded paper and fold one of the long sides up two inches to form a pocket. 3. Glue the outer edges and the center (on the valley/crease) of the two inch fold with a small amount of glue.
- 44. o A LAYERED LOOK BOOK FOLDABLE 1. Stack four sheets of paper (8 ½” x 11”) together, placing each consecutive sheet around ¾ of an inch higher than the sheet in front of it. 2. Bring the bottom of both sheets upwards and align the edges so that all of the layers or tabs are the same distance apart. 3. When all of the tabs are equal distance apart, fold the papers and crease well. 4. Open the papers and glue them together along the valley/center fold.o A JOURNAL RESPONSE THREE QUARTER BOOK FOLDABLE 1. Fold a piece of 8 ½” x 11” paper in half horizontally 2. Fold it in half again horizontally. 3. Unfold the paper (just once so that it is still folded in half) and cut up (along the edge of the paper at the center where you can see the crease) to the mountain top 4. Open flat, lift the left-hand tab. Cut the tab off at the top fold line.o A STUDENT INTEREST BOUND BOOK FOLDABLE 1. Fold two pieces of ¼ sheet paper (4 ¼” x 5 ½”) separately in half horizontally 2. Place the folds side-by-side allowing 1/16” between the mountain tops. Mark both folds 1” from the outer edges. 3. On one of the folded sheets, cut-up from the top and bottom edge to the marked spot on both sides. 4. On the second folded sheet, start at one of the marked spots and cut out the fold between the two marks. Do not cut into the fold too deeply, only shave it off. 5. Take the “cut-up” sheet and burrito it. 6. Place the burrito through the “cut out” sheet and then open the burrito up. 7. Fold the bound pages in half to form a book.
- 45. o A TWO-TAB POINT OF VIEW BOOK FOLDABLE 1. Fold a piece of (4 ¼” x 5 ½”) paper in half horizontally 2. Fold it in half again horizontally 3.

An arrangement of five identical squares in a plane, attached to one another edge to edge. Is a polymino composed of five congruent squares, connected long their edges (which sometimes is said to be an orthogonal connection).How it is done or constructed? Know that there are 12 pentominoes shape. They are named for the letters they represent: F I L N P T U V W X Y Z. A pentomino is a shape composed of five congruent squares connected by at least one side. Since there are twelve pentominoes made of five squares each, pentomino puzzles are played on grids of 60 squares: 6 by 10, 5 by 12, 0r 3 by 20. Make your grids. Sketch them on one sheet of graph paper. Cut them out, then trace them on two card stock. Go over the lines with a permanent marker to make a boarder, then cut the grids out and set aside. Make your puzzle pieces. Sketch out one of each pentomino onto graph paper. Cut them out and trace them onto card stock. Color the pentominoes. Try to use one color for each piece if you have enough markers available. Otherwise, just make it as colorful as possible. Then, cut out the pieces and set aside. Construct your folder, which will contain your puzzle. Open the folder and staple the zipper bag to one side of it. Your grids and pieces will be stored in the bag when you are not playing with your puzzle. Put the paper clip on the other side. This will be used to hold which ever grid you are playing on at that time. Play pentominoes. Take a grid out of your bag and clip it onto the folder. Using your pentomino pieces, fill the gried by leaving no empty spaces and overlapping no pieces. Each grid size has several olutions, so enjoy fiding them all.
