Geogebra - Dynamic Mathematics for Everyone

GeoGebra is an interactive geometry, algebra, and calculus application, intended for teachers and students. Most parts of GeoGebra are free software. GeoGebra is written in Java and thus available for multiple platforms.

Its creator, Markus Hohenwarter, started the project in 2001 at the University of Salzburg, continuing it at Florida Atlantic University (2006–2008), Florida State University (2008–2009), and now at the University of Linz together with the help of open-source developers and translators all over the world. Currently, the lead developer of GeoGebra is Michael Borcherds, a secondary maths teacher.

After a successful Kickstarter campaign, GeoGebra plans to expand their offerings to include an iPad and Android version.

GeoGebra is dynamic geometry software. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly on screen, or through the Input Bar. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra to make conjectures and prove geometric theorems.

Most parts of the GeoGebra program are licensed under GPL and CC-BY-SA, making them free software. However some parts, including the Windows and Mac installers, have a license which forbids commercial use and are therefore not free software.

Download Free Software geogebra here.  And GeoGebraTube is the official repository of GeoGebra constructions and GeoGebra related resources.

Mount Everest, How Tall Is It? - A Mathematics Mystery

Last night I started to read Mount Everest, The Reconnaissance 1921 which I downloaded for free from Google Books. In the introduction there is a three page explanation of the methods used to measure the height of Mount Everest. An explanation of the differences in measurements is also provided in the introduction. Part of that explanation includes differences in snow fall, cyclical deviations of gravity, and differences atmospheric refraction when observations were made. I'm not a mathematics teacher and will never pretend to be one, but reading that introduction did get me thinking about a possible mathematics lesson.

Applications for Education

Turn to pages 10 through 13 of Mount Everest, The Reconnaissance 1921 and read about the difficulties of accurately measuring Mount Everest in the late 19th and early 20th Centuries. It's interesting to note that most accepted measurements were more than 100 feet higher than today's accepted measurement. Tell your students that Mount Everest has shrunk over the last 100 years and ask them to solve the mystery of the shrinking mountain. 

On a mildly related note and on a promotion of a Mainer note, Snow in the Kingdom: My Storm Years on Everest by Ed Webster is one of the best books ever written about Mount Everest. If you enjoy good adventure stories and or stories about overcoming personal struggles, I think you will enjoy Webster's book. For my money, and I own two copies of it, it is far better than Krakauer's Into Thin Air.

Tips on using the method of creative learning in learning mathematics

This article provides a set of tips for raising your awareness of learning styles as a major factor in how children learn. These tips are adapted from the resources listed at the end of this article.

The tips are based on the Dunn & Dunn Learning Styles Model developed by Professors Rita and Kenneth Dunn to assist the New York State Department of Education in improving the effectiveness of instruction for students not demonstrating sufficient progress. The model is based on 20 elements, divided among five categories (called stimuli in the model), that affect learning. Use of the model has been statistically proven to improve student performance.

The model's five stimuli are environmental, emotional, sociological, physiological, and psychological. A nice illustration of the stimuli and elements is here. A very similar model, the Learning Styles Pyramid Model is illustrated here.

The first half of the tips are not specific to Math and apply to a broad range of learning situations. The second half are Math-specific.

1. Ask your child how he learns best
2. Notice whether your child learns better in the morning, afternoon, or evening
3. Introduce a lesson by relating its content to your child's life
4. Use anecdotes and stories to convey the practical relevance of lessons
5. Use humor, songs, poetry, cartoons, drama and color to capture attention and stimulate receptivity and learning
6. Use pictures, drawings, graphs, illustrations, and charts to engage the visual sense
7. Allow flexibility in lighting (natural, bright, soft, dim, incandescent vs. fluorescent)
8. Allow flexibility in seating arrangement (experiment with casual and relaxed seating)
9. Encourage use of white boards, bulletin boards, outside areas, and large floor space for your child to demonstrate what he is learning
10. Notice whether the room is too cold or too warm for your child
11. Try incorporating soft background music into the learning environment (with no lyrics to distract)
12. Notice whether your child prefers to work alone, in a group, or with adult or authority figures
13. When working in groups, encourage a 60 second break every 15 minutes to review with others, what the children just learned
14. Explore with your child if he learns best while snacking
15. For learning about numbers and operations try counters, Cuisenaire rods, blocks, chips, abaci, wooden cubes, and counting sticks
16. For more advanced learners, try number lines, charts, computers, and calculators
17. Use card and board games and let your child create his own games
18. Encourage your child to create his own word problems to provide a context for what he 's learning as well as to support his computation
19. In early algebra lessons, start with tables and graphs to show relevance of the material
20. Use geometric models, geoboards, rectangular dot paper, geoblocks, tiles, tangrams, and mirrors to sketch and record shapes
21. Have kids learn about points, lines, angles and other geometric ideas by using their hands and arms to illustrate the ideas. This can be especially fun if there is a group of kids to illustrate these ideas together.
22. Support learning of measurement through instruments: rulers, meter sticks, tape measures, trundle wheels, graduated beakers, measuring cups and spoons, kitchen and bathroom scales, thermometers, timers, clocks, and protractors
23. Try having your child work out a problem on a white board and see if having him stand makes a difference
24. Encourage your child to talk about what he learned, give feedback, and show him how to apply what he has learned to his life
25. Use story books to teach Math concepts such as time, money, measurement, and problem-solving
26. Teach about data analysis, probability, and statistics through newspaper graphics, newspapers, and charts. Also, use dice, coins, cards, colored cubes, chips, spinners, graph paper, squares, calculators, and computers.

I hope when our children no longer allergic to aftermath read this article , and to the parents this is a reference to educate their children to like mathematics .

Sharpening Mathematical Logical Intelligence Children

Indeed, every child is born with the potential of smart and the uniqueness of each that allows them to be intelligent. Howard Gardner in his Multiple Intelligences have, said there were eight intelligences in humans including: verbal/linguistic intelligence/language, logical mathematical intelligence, visual/spatial intelligence/spatial, musical/rhythmic intelligence, kinesthetic intelligence, interpersonal intelligence, physical intelligence, and intrapersonal intelligence naturalist. Duties of parents and educators is maintaining the qualities that formed the basis of intelligence to survive until the child was growing up, by giving environmental factors and good stimulation to stimulate and to optimize brain function and intelligence of the child.

Basically every child was awarded the logical mathematical intelligence. Gardner defines logical mathematical intelligence as the ability of scientific reasoning, computation of mathematically, logical thinking, inductive/deductive reasoning, and sharpness of abstract patterns and relationships. Can be translated as well as the ability to resolve issues related to the needs of mathematics as a solution. Children with this capability will be thrilled with the formula and abstract patterns. Not only on the number of maths, but also on the rise in activity that is both analytical and conceptual. According to Gardner there is a link between mathematical intelligence and linguistic intelligence. In mathematics, the child's ability to analyze or describe logical reason, as well as the ability to construct a solution of the problems that arise. Linguistic intelligence required for merunutkan and menjabarkannya in the form of the language.

Still according to Gardner, the mathematical characteristics of intelligent logical child at the age of a toddler, child loves a explore to satisfy her curiosity like exploring every corner, observe the things that are unique to her hobby of fiddling with the object as well as, do a test run. Like what if my feet in a bucket full of water or curious composing puzzle. They are also often asked about different phenomena and are demanding an explanation of each logical questions asked. In addition children also love to classify various objects based on color, size, type and others and was fond of counting.

Stimulation of daily activities around us.

How we stimulate mathematical intelligence logical children from an early age? Bagimana we instill logical mathematical concept early on? We can introduce first understanding of mathematics from an early age from our surroundings and everyday experience as well as giving the child the stimulation of support. Of course this was done without coercion and pressure, and through the game-the game. In the education, the role of parents is irreplaceable and the House is the main base of education of the child. Many games of exploration that can hone the ability of mathematical logic, but of course this has to be adapted to the age of the child. When toddlers play sand, real child is animating his muscles are trained so that future child halusnya motor capable of holding a pencil, draw and others. By playing the real child study estimation of sand by pouring or take the later all that's in the math.

When we introduce figures on children do not only as a symbol, for example we have two oranges, provide two citrus fruits. So the children know about the concept of numbers and number. The song can also be a medium for introducing various themes about the numbers. There are five songs such as balonku. Or we can create his own songwriting simple while visualizing our fingers as a tool to count, so that gradually the child easily captures the abstract concepts in numbers

After the children get to know the numbers 1 to 10, then the number zero was introduced to Provide an understanding of the concept of number. zero in early childhood is not easy. This game can be done by calculating a magnet affixed to the refrigerator. Try taking one by one and ask the children count the remaining. Do periodically so that the magnets on the fridge is no longer attached. While it can be shown that the views on the fridge is 0 (zero) magnet.

While in the kitchen, we can introduce the concept of the classification and grouping of related to the concept of mathematical logic, for example by means of the child are asked to classify the vegetables based on color. Arithmetic skills in operation of a simple number, such as when three apples eaten one then the rest is how. It could also create geometric forms through pieces of vegetables. Once in a while do also make cake with activities, other than to increase familiarity and warmth of the family, children can also learn mathematics through activities whereas, take the necessary, calculate the time. Cook while looking recipes also trained the skills of reading and learning vocabulary. Don't risaukan a State of the kitchen would be dirty and cluttered with flour and scattered belongings, because such an ad slogan that dare dirty is good. The child is happy and unknowingly they learn many things.

We can also provide mathematical concepts such as quantity, such as understanding how the number of fish in the Aquarium. When relaxing in front of the home, children are invited calculate how much a passing motor in 10 minutes. Recommend also the concept of comparison such as larger, smaller and so on, for example by asking the child with bread donut bread cake which one size larger. When we introduce and inquire on the child that the car is moving faster than the motor, palms taller than trees, guava, or bags heavier than his older brother bag, in fact it is already included in the concepts taught pace, length and weight, so that the function of intelligence mathematics become active.

For activities outside the home, when we invite children to shop, engage it in the transaction so that the train operating skills such as addition and subtraction. It could be with the game store or the market the market with friends.

Traditional games also can stimulate and enhance mathematical intelligence such as congkak logical child or dakon game as a learning tool is also useful to train and arithmetic ability of fine motor manipulation primarily train the forces of the hand at a later date is useful for getting started writing. As long as children are required to follow focus play which in turn will train a child's concentration and perseverance is needed when the child attends lessons in school.

Smarter by playing to savvy child

Why much stimulation through games and play activities that fun? Because the play is going to make children able to express ideas and feelings and make the child become more creative. The play also will exercise cognition or ability learned the child based on what is experienced and observed from its surroundings. When playing a challenging game, children have a chance in solving problems. For example, compose or play lego pasel. Children exposed to troubles, but it's not a matter of fact, it's a game that needs to be done. The problem of bringing boys unconsciously trained to solve a problem. This will strengthen the ability of children out of trouble. For example when being menalikan, the child will attempt to use all his skill to complete up to completely.

Thus the children will love the math because math lesson turned out there were around them and they know the purpose of learning math. Of course this should be supported with a pattern of teaching mathematics in schools that are fun, creative, contextual, realistic, emphasis on processes and student understanding and problem solving, creative in promoting and teaching the concept of mathematics as well as with a wide variety of games and props that would be interesting so math lessons are fun and eagerly awaited. In the book entitled Learning is Most Effective When It’s Fun.

Teaching Geometric Constructions using Math Open Reference

Teaching geometric constructions has always been a challenge. The rules are easy enough - compass, straightedge, no measuring. But for the teacher the challenges come quickly. How to actually demonstrate them in class? How will the students remember the steps when trying it themselves? What happens when they do the homework?

In the classroom

To demonstrate the constructions in class we have the usual choices:

• Compasses and straightedge on a whiteboard or overhead projector.
• Software such as Geometers Sketchpad (GSP) or GeoGebra.

These have the obvious drawbacks; the vertical drawing surface or overhead projection screen is awkward and the students cannot take it home. Using software is OK, but the compass tool only draws whole circles which, while technically correct, winds up producing rather confusing images for this task, and does not show the steps involved. The Math Open Reference website offers a third option. In the chapter devoted to constructions (here), there are most of the Euclidean constructions taught in high school. Each one can be stepped through one step at a time, or be let to free run all the way through. Each one also has written instructions for those who prefer that.
Using a projector you can show each construction step by step while you discuss it with the class. The compass actually looks and acts like a compass, and it can draw partial arcs just the like the real one. The straightedge and pencil looks real also.

Fig 1. Freeze-frame of the angle bisection construction.

Stephen Corcoran, Head of Mathematics at St Stephen's School in Perth Australia reports after using the construction pages in the classroom:

"The lesson was a huge success. Displaying your construction animations greatly increased student understanding, motivation and 10x more efficient. Also they can always visit your site themselves if they wish."

In the Lab

The next problem arises when the students try to do it themselves. They have to rely on memory to redo what they saw a few minutes ago in class. This memory is typically not very good. Not until they have done it themselves a few times will they really retain it. The ultimate goal of course is to get to the point where the visual aid is no longer needed and they can perform the constructions in a test unaided. Using Math Open Reference, they can bring it up on a computer and follow along with the animations, pausing between steps. This leads to a high degree of success and hastens the time when they can do it unaided.
Some teachers do this in a computer lab setting while they walk around looking over shoulders to find the students who need some extra help. Teachers report that this activity is very engaging. According to Roy Chancellor, a math teacher in Scottsdale Arizona:

"Animated constructions are absolutely indispensable for guiding the students at their own pace. It would be next to impossible to teach these constructions in whole-group format. The students were engaged throughout the lab."

At Home 

The third challenge arises when the students are at home. Once again, they have to recall what they saw in class and try and reconstruct the figures from memory. If they have trouble with this, the only recourse has been a written set of instructions, and these instructions are very hard to write - a bit like trying to describe how to tie shoelaces.
Because the Math Open Reference animations are freely accessible on the web without any special downloads or software, they can again see the step-by-step animations and practice at their own pace until they get it down. They are seeing the exact same animations they saw at school.
Software like GSP is less useful here because:

• The student has probably not purchased it.
• The sketches do not show how they can be produced using real drawing instruments.

Making it Concrete

Constructions are taught as a fundamental part of a geometry curriculum, but they have other values. Some geometric concepts can seem a little abstract to some students. By linking them to physical constructions, the ideas become more concrete in the student's mind.
Again, Roy Chancellor:

"In my HS geometry class, we're doing a unit on properties of triangles, such as circumcenter, incenter, centroid, and orthocenter. After learning various theorems about these special locations, my students used your construction pages to create each one. After making the constructions, they used measuring tools to verify each of the theorems from earlier in the week. It was an excellent way to connect the book knowledge to something they created."

Conclusion

It might be said that this is just rote "see and do", not real learning. But there is another view. Once the constructions have been practiced over and over and internalized, the training wheels can be cast aside. From that base of confidence, the discussion can be started into the real meaning of the constructions and the analysis of why they actually work.

WIRIS cas covers all mathematical topics from primary school to university level (Calculus, Algebra, Geometry, Differential Equations...).

Empower your Moodle Quiz module with mathematics

Moodle Quiz allows you to create questionnaires for your students. If you would enjoy such features as randomised data and automatic evaluation and feedback, then WIRIS quizzes is your solution. This component enhances the existing question types of Moodle with the power of mathematics:

• You keep full control over random data (create a random matrix with a set range, for example, or a polynomial with a double root).
• Add 2D or 3D graphics in your questions, answers and feedback.
• The answers of the students are automatically evaluated and their feedback is provided taking into account the randomness of the question and that of the answer!
• The evaluation checks for mathematically equivalent answers to the expected, but not exactly the expected solution. For example, if the solution were , we want the system to interpret  as a correct answer. This can only be achieved via a calculation engine as WIRIS.
• The teacher decides if the student has access to a calculation engine session or a formula editor for introducing their answer.
• The production and modification time of the exercises is reduced to the minimum through simple and visual edition.
• NEW: WIRIS quizzes 2 allows you to control the format of the answer provided by the student: request it to be simplified, factorised, etc. Come and see us present the latest features at our nearest events.

Create graph "Love Function" Using Google

Google continuesly spoils its users, and this time especially for you – the math lovers. Google has announced its new service by integrating a facility that allows users to plot graphs of mathematical functions in its search engine.

Simply start with the command plot or graph, and type the functions to be plotted using simple syntax. Google will display the graph function in a wink.

Here are the graphs of some basic functions.

plot cos x, x/5, exp x

Below is a graph of the "love function" that is panetrated by a straight line.

graph sqrt(cos x) sin(300 x) + sqrt(abs x) - 1, x - 0.5, from -2 to 2

If you want to do advanced computation online, you can try Wolfram Alpha that use Mathematica as its computational engine.

How to Make Technology in the Classroom

The ISTE Classroom Observation Tool (ICOT) is an observation tool developed by the International Society for Technology in Education (ISTE). The association’s purpose is to engage in advancing excellence in learning and teaching through technology. The association is also responsible for developing the National Educational Technology Standards (NETS) for students, teachers, and administrators. The classroom observation tool was designed to evaluate the amount of technology being used in the classroom as well as its effective use based on the NETS.

Why use ICOT as an Observation Tool?

There are several good reasons for using an observation tool such as ICOT to evaluate the effective use of technology in the classroom. The authors report that technology spending in education will reach $56 billion by 2012. A final reason for using such technology to evaluate the use of technology in the classroom is for administrators to better prepare and plan professional development for teachers in the use of technology. The components of the ICOT instrument consist of setting, groups, activities, technology, NETS, and charts. The technology component is the meat of the observation tool. The NETS component reports on what teacher or student standards are being taught or used during the lesson.

Observation

For the practical purposes of this article the writer used the ICOT instrument to observer a fifth grade teacher at the writer’s school. The teacher is a fifth year teacher who has taught traditional classes as well as boys’ single gender classes. There are five fifth grade classes containing approximately 23 students per class. Teachers are encouraged to engage students in the use of technology at least on a daily basis.

There were 23 students in the classroom at the time. Each student had their own lap top computer provided by the school. Students were creating, researching, collaborating during the lesson. Second, the teacher created a developmentally appropriate learning activity for fifth grade boys. Third, the technology used during the lesson enhanced instruction. Fourth, the technology supported learner-centered strategies. Fifth, the teacher applied technology to develop students’ creativity. Finally, the teacher modeled legal and ethical technology practices by using the interactive board to show examples.

ICOT is a useful tool for administrators to safely document the effective use of technology in the classroom. The tool allows educators to observe technology being used by both students and teachers based on the NETS. Many general classroom observation tools touch on technology in the classroom, but very few if any go in to as much detail as the ICOT does. As administrators observe in classrooms and upload data to the website, district administrators can generate and view reports that can guide professional development and future purchases.

Effective Classroom Management

Let's not also forget that a large proportion of pupils in our classes are EBD, ADHD or on the autistic spectrum and as such, have a genuine need for unambiguous, precise instructions.

The following example illustrates this need perfectly:

At the first EBD centre I taught in, the pupils (11-14yrs) were allowed on the yard at break to play football.

The instructions, which sound incredibly pedantic, broke the short 200 yard journey into very small segments and went something like this...

(wait for them to stand in silence before giving next instruction) "Walk across the hall to the fire door and wait in line." "Go though the doors and walk down the corridor to the outside doors. Here's another example to show how vague instructions are such a waste of time...

On the way back from the yard at break one day, Mark was deliberately lagging behind, bouncing the football.

"Come on Mark, quick... Hurry up Mark, lessons have started... Mark! Break's over Mark!... Quickly Mark!... Mark!... Mark then proceeded to enjoy the undivided attention of two members of staff as they altered their approach from friendly cajoling and encouragement to aggressive shouting and frustrated threats. Had the teacher altered her instruction slightly at the beginning, the situation could have been very different. "Mark break is over.
