The TI-30 ECO RS is the most popular scientific calculator for school, work and home. The advantages are obvious: the TI-30 ECO RS has comprehensive functionalities, is easy to use and also particularly environmentally friendly. The Blue Angel... protects the climate calculator is solar powered and made from recycled plastic. Function overviewCommon school calculator for quick solution of mathematical, scientific and statistical tasks. Fractional calculation, trigonomic and one-dimensional statistics functions. With ten-digit 2 exponent display. 3 memories. The Blue Angel awarded the Blue Angel thanks to full solar operation and housing design made of recycled plastic (highly sensitive, powerful solar cell ANYLITE). Clear, clearly arranged keyboard with colour-coded keys. Quick access to all important features from maths and science.Fraction calculation in the 4 basic arithmetic types. Convert fractions to decimal and vice versa. Trigonometric calculations (including Inverse) in deg, wheel or degree. One-dimensional statistics with mean, standard deviation, data sum and square sum formation. Convert polar to right angle coordinates, convert degrees, minutes and seconds to decimal degrees.What types of calculators are allowed on the high school exam? Computer use in lessonsExperience shows that the use of computers promotes student communication with each other. Teachers know the phenomenon that even quiet students start talking to each other and show something to their neighbor. Students mutual explanation of operation and arithmetic paths among themselves strengthens argumentative and social skills and your child benefits in their personal development. Does my child learn mental arithmetic?Mental arithmetic is important and, as well as handwritten calculation, is consolidated by selected teaching and learning units. Your child should be able to assess the result of calculations in advance and evaluate it afterwards. Teachers pay attention to this skill. Typically, arithmetic skills are deepened at regular intervals - this is also envisaged in modern curricula. Comparative studies prove that computing skills are not lost due to computer use. Even more - valuable new skills are gained. Maybe use a computer right away?Where are TI-30 and TI-34 scientific calculators allowed?The constantly available calculator is less of the focus on the outside, is only pulled out of the pocket if necessary, and can therefore be easily integrated into the learning process. It is optimised as a special tool for STEM (mathematics, computer science, science and technology). Measured value acquisition can be done both in the physics laboratory and in the great outdoors. The evaluation of measurement data is done in the classroom or at home. The calculators come with professional support, training and teaching materials that enable particularly educational and targeted teaching.When considering purchasing or using computers, it is important to note that there are also restrictions. A walk into a PC room cannot be spontaneous. Even with notebooks, you are not as flexible as with calculators. In addition, computers tempt to use a collection of different freeware programs that do not work well together. Your child needs a lot of learning time to learn and keep the operation of the different programs. For this compiled collection of applications, there is currently not a mature service with a professional supervision of the teachers and students.Awarded the Blue Angel The TI research programmeFor more than 20 years, Texas Instruments has used extensive research to continuously contribute to further improvement of mathematical and natural science teaching. Here, Texas Instruments works very closely with the ministries of culture and the universities. The results flow into both product development and the design of teacher support programs.This - independent and objective - research is carried out in partnership with the Institute of Education Sciences of the Federal Department of Education and the National Science Foundation in the United States, in Europe with the Ministries of Education and the European Union, and with major research universities around the world. TI adheres to a strict code of ethics in all research activities that ensure the highest standards of independent and objective research.
