scientific and graphing calculators

It is possible to use scientific and graphing calculators that can be used by students who are blind?

Calculators They are extensively utilized at every educational level. Calculators can be used to carry out statistics or scientific calculations, alter matrices and plot functions on graphs can be beneficial in studying sophisticated mathematics. Although the majority of graphing and scientific calculators aren't accessible to people who have the ability to see but there are alternatives for those who visually impaired users to use these calculators in a way that is effective.

There are many talking science calculators are on the market, though each calculator is not able to function to the exact specifications expected in all settings. Therefore, an evaluation of features required by the student needs to be completed to ensure that the appropriate calculator for the student is chosen. Susan Osterhaus at the Texas School for the Blind has put together a comprehensive overview of features of different scientific calculators which can aid in the selection process. The calculator, Orion TI-30XS MultiView talking Scientific Calculator has the potential to be highly respected and well-respected scientific calculator that may meet the requirements of a wide range of students.

Another option is the portable electronic notetaker with the latest math-related features. Certain notetakers have speech synthesis and Braille that refreshes . They can be used by those who are blind for logarithmic and trigonometric calculations. Consult with the manufacturer to determine if the scientific calculator function could be used.

There are other programs which can provide speech-based access to a scientific calculator application. Some of them emulate the conventional calculator interface and some can also provide an audio interface to the graphs. For example you can use the Audio Graphing Calculator (AGC) is an example of an accessible Windows-based software application that features graphing calculators that are capable of visualizing graphs in both audio and visually as a sonified graph.

For more information on access these scientific and graphing calculators see the accessibility resource, accessible Calculators available from GeorgiaTech Center for Assistive Technology and Environmental Access (CATEA).

The unit ppm can be utilized in many branches, and in many different ways. The use of ppm needs to be specified within the input fields below, so that it will be converted into the appropriate unit. For more information on the usage of ppm look up the documentation below.In the input box in your Molecular Weight field, you choose from the drop-down menu , or type in your own number for the molecular mass of gas. If the molecular weight of gas is not obvio...

LENGTH CONVERTER

  LENGTH CONVERTER Choose the length you'd like to use, then input the amount that you'd like converted to an alternative measurement. Type in the length measurement into the "From" field, and choose the measurement you want to convert it into in the "To" field.   The result will be displayed in the "To" field right after you click on any number. It is the term"length," which you've probably heard of, is defined as an exact  measurement  of anything from one end to the other.   It's hard to find precise measurements for converting miles to kilometers.   Sometimes, we require an estimation of how long it takes other people to travel to their destination, or how long it takes to arrive there. That's the reason why length converters can be useful when making calculations.   Measurement  Converter functions as an tool that can be utilized according to the guidelines and since it is able to change any length to another, it could he...
