scientific and graphing calculators

Are there scientific and graphing calculators that are accessible to blind students?

Calculators are extensively used in every educational level. Calculators can be used to carry out statistics , scientific calculations, alter matrices and plot functions on graphs are particularly useful for studying advanced mathematics. While the majority scientific and graphing calculators aren't accessible to people with visual ability, there are options available to those who are visually impaired to use these calculators in a way that is effective.

There are many talking scientific calculators are available on the market, however the calculators do not all function to the exact specifications required on all scales. Therefore, an assessment of features required by the student needs to be done so that the most appropriate calculator for the student is chosen. Susan Osterhaus at the Texas School for the Blind has written a comprehensive review of features of different speaking Scientific calculators which could aid in the selection process. This calculator Orion TI-30XS MultiView Communicating Scientific Calculator has the potential to be highly respected and highly-respected scientific calculator that may meet the needs of various types of students.

Another option is the electronic notetaker portable that comes with the latest math features. Certain notetakers are equipped with speech synthesis that works with Braille that refreshes . These can be utilized by students who are visually impaired for trigonometric and logarithmic calculations. Make sure to check with the manufacturer of the notetaker to determine whether there is an scientific calculator function can be used.

There are other programs that allows the ability to speak to an scientific calculator application. Some of them emulate the standard calculator interface and some can also provide users with access via sound to graphs. For instance the Audio Graphing Calculator (AGC) is an example of a user-friendly Windows-based application and features graphing calculators that have the capability of displaying graphs both audio and visually as a sonified tone graph.

For more information on accessibility to and use of scientific and graphing calculators see the accessibility resource, accessible Calculators on the GeorgiaTech Center for Assistive Technology and Environmental Access (CATEA).

To learn more about accessible math, take a look at the following Knowledge Base articles What are some ways to make Braille maths material? and why is accessibility to math important?

Random Number Generator

Random Number Generator Random Number Generator Utilize this generator in order to generate an completely randomly and cryptographically secure number. It generates random numbers that can be used in situations where reliability of the results is required for instance, when shuffling a deck cards for poker, or drawing numbers to win prizes, lottery tickets or sweepstake. How can you pick an unlucky number from two numbers? This random number generator will select the most random number among two numbers. To get, for instance the random number that is between 1-10 as well as 10, input 1 in the top field and 10 into the bottom, then press "Get Random Number". The randomizer will select a numbers between 1-10, randomly. To generate an undetermined number between 1 and 100 then you can use exactly the same thing as above however, you place 100 at the bottom of the randomizer. To simulate a dice roll, it is recommended to use a range of 1 to 6 for a standard si...

What Is a Calorie Deficit and Is It Safe?

What is Calorie Counting? Calories are counted, but not everyone has to count them! What Is Calorie Counting? Calorie counting is the method of recording the calories (or Kilojoule) amount of every beverage and food item that you consume each day. It is done with the diary of food, an application or by simply putting the data on a spreadsheet. Alternatively, calorie-based meal plans may be prepared in advance and then adhered to. Do Calories Count? There are two major opinions on thissubject: Calories and only calories count and should be recorded. Calories do not matter, it's what macronutrients (i.e. carbohydrates, protein, fats) that determine everything. When it comes to consumption and output of energy, calories can be described as everything. In terms of nutrition and health the macronutrients matter. Consider this If you decide to adopt an 1800-calorie a day diet - would you be able to get all the 1800 calories in die...

Random Number Generator

Random Number Generator Utilize this generator to receive an absolutely randomly and cryptographically safe number. It produces random numbers that can be used where unbiased results are crucial in games like shuffling decks of cards in playing poker or drawing numbers to win sweepstakes and giveaways. What do you do to determine a random number from two numbers? You can use this random number generator to generate an authentic random number among any two numbers. For example, to create an random number between one through 10 (including 10 ), input 1 in the upper box, then 10 into the secondfield, after which press "Get Random Number". The randomizer will generate the number 1 to 10, randomly. In order to generate an random number between 1 and 100, repeat the process similar to the one above, but make sure that you put 100 for one of the fields within the randomizer. To simulate a dice roll the interval should be from 1 to 6, for an ordinary six-sided di...
