TI-Nspire, Future of Texas Instruments

!±8± TI-Nspire, Future of Texas Instruments

For over 15 years, Texas Instruments has owned the graphing calculator marketplace. Since the release of the TI-81 graphing calculator, TI has grown their following by improving that original TI-81 into the TI-82, TI-83, TI-83 plus, and eventually, the TI-84 plus. The TI-84 plus is still remarkably close to the TI-81. Despite the fact that the TI-84 has been incredibly popular, it's a dated device. Texas Instruments realized it was time for a new platform.

So in in 2007, Texas Instruments made public their new calculator, the Nspire. The improved features from the old product line were striking. On the old TI-84, the menus were odd at best, nonsensical at worst. It was hard for beginners just to figure out which button to push, and then the menu would fill the entire screen. With the Nspire, drop down menus are the norm, meaning students can stay in the screen they were working on and pull down a menu the way they would on a computer. Among other features are the highest resolution screen available on a calculator, the ability to save documents, a spreadsheet mode, mathprint for virtually all mathematical symbols, and a vastly improved system for graphing equations, simplifying the 84's ancient interface.

Frankly, the TI-Nspire made the TI-84 look like a dinosaur, and yet, the first reaction in the market was tepid. Why? TI didn't anticipate the reaction of two influential groups. First, despite positive TI-Nspire review s, educators were initially hesitant to adopt the Nspire. Many had just spent too much in the old TI-84. That was the case both in terms of the time invested learning the TI-84 and in terms of the school budget invested on classroom sets of TI-84 calculators. Texas Instruments tried to ease that consternation by offering a TI-84 keyboard that made the TI-Nspire look and act like a TI-84, but many felt that defeated the purpose of the Nspire. The other group that was cautious about the Nspire was the hacker community. At first, the TI-Nspire didn't offer programming as an option. Later, an OS upgrade offered some programming, but it wasn't enough to win over the programmers.

Lately, the Nspire has been gaining traction. Texas Instruments has noticed, getting rid of the Silver Edition of the TI-84. Now, however, TI finally faces competition from a competitor's calculator, not just its own TI-84. Casio has revealed its answer to the TI-Nspire. The Casio Prizm offers many of the same features as the TI-Nspire at almost the same cost, but offers two extra features with backlighting and the ability to display color pictures. The Prizm is set to be out in January 2011.

The Nspire finally has traction with buyers, but will face tough competition from the Prizm. The question now is whether the educator loyalty and user support they've created over the last 20 years will be enough for the TI-Nspire.

Effects of Technology on Education

!±8± Effects of Technology on Education

Education has changed significantly in the last twenty years. One of the main reasons education has undergone so many changes is because of technological development. In 1990, computers and other forms of technology served a minimal role in the classroom. Today, many if not most college students attend class with a laptop. I am writing about some of the biggest advantages technology gave to education.

Technology has made research much easier. Before online Encyclopedias, Google Scholar, JSTOR, and other online research tools were available, students were forced to spend numerous hours in the library. With the new tools, students can conduct research faster in the comfort of their homes. With Google and other search engines, students can find relevant information faster and more efficiently. Also, there is no more need for intensive memorization as information is more readily available.

New also technology allows for a faster, more efficient, and more interactive classroom experience. With Powerpoint presentations and projectors, there is no need for blackboards and whiteboards. With clickers, students can take quizzes during the classroom.

These developments also help improve tutoring services. Online tutoring programs are becoming available. One-on-one in-home tutoring programs are also being aided these developments. Tutors can bring laptops to sessions allowing them to look up information, and show examples to the student more easily.

Wi-fi technology allows students to study in more comfort and a more ergonomic setting.

New mathematical software such as Maple and Mathematica allows students to make a computer algebra computations more easily. Software like Matlab and Scilab allows students to make numerical computations more easily. There is no more need for a line rule. Advanced Texas Instrument and Casio calculators allow students to solve equations and produce graphs. Online software such as Webassign allows students to submit mathematics assignments online with instant feedback.

The internet allows students to read books and educational supplements at home. There is no need to go to a bookstore or library. Since many of these sources are open source or funded by advertising, students can access these materials for free. Wikipedia, Wikibooks are good examples. Students can learn more without leaving their house.

College applications and job applications can now be complete online. Students can deliver important paperwork to universities and employers at a much faster rate.

Online education allows more students to get an education. Handicapped students, students that have to travel a lot, and students with jobs can now complete their degrees wherever they go with a flexible schedule and often at their own pace. Due to its lower costs, online education also benefits lower-income students.

Technological development allowed the creation of new IT jobs and improved economic development in general.

Not all effects of technology on education are positive. Technology also allows students to cheat more easily. However, new technology allows instructors to detect plagiarism. Technological developments can also discourage critical thinking since answers are more readily available. Technology also encourages students to spend their time doing other activities such as playing video games and participating in social networking.

Overall, technological development in the 1990s and 2000s appears to be beneficial to education. Currently, technology improvement follows Moore's law which states that computers become twice as efficient approximately every two years. Today, one can purchase a well performing personal computer (without a monitor, software, and other accessories) for as low as 3.99. Recently, I have not spent over 0 on a desktop computer and it allowed me to do very advanced computations like high-sample Monte Carlo algorithms. If the trend continues, students all over the world will be able to afford desktops and laptops contributing to a better global education.

Stop now almost every secondary school mathematics teaching in America, and you will find that Texas Instruments graphing calculator to dominate the scene. Back in the early '90s, Texas Instruments has begun a model published a series of graphing calculators, which were all very similar, with only minor updates to the hardware and operating system: the TI-81, TI-82, TI-83 and, finally, the TI-84, in 2004. All were received with great popularity, and as each successorsimilar to those that preceded it, it was easy for adults and children to take hold.

After a decade of Texas Instruments has dominated the computer market, one might ask if there is another choice out there are more. The short answer is "yes", and comes with Casio America. Casio is being promoted in two ways in recent years, the simplicity and convenience. Their products live up to the press on both sides.

In terms of cost, Casio products are clearlyless than the TI products are competing with them. Of course not comparing apples with apples, but the Casio 9860GII 9750GII and both are much less expensive than any graphing calculators. The 9750GII actually retails for under $ 50, making it by far the graphing calculator expensive lease from a top producer in the market. The graphical menu system on these devices is also extremely easy to use for beginners.

The future of Texas Instruments, however, is the TI-Nspire. ImportedIn 2007, this unit high-resolution grayscale screen, drop-down menu, point and click interface and the ability to create documents. Casio has no quarrel with this computer until now had to compete. In October, Casio announced the new calculator, the Casio Prizm. There is a computer with high-resolution color graphics with the ability to function directly on the photo. The video marketers do not hide the fact that Casio aims to TI-Nspire with this version.

The battlefor market dominance again. Texas Instruments has a control cable, but now Casio has a new innovative product. If the Prizm Casio released in the spring of 2011, expect a great fight for market share between the two companies.

"Mathematics is difficult. Mathematics is complicated. Mathematics is boring."

Fortunately or unfortunately, it is important for mathematics. Mathematics is the most common theme in almost all professions, and often demand high-paying job for someone who can "deal".

According to the 2007 Department of Education statistics, only 31% of students score at or above the eighth-level "master" of standardized tests of mathematics. In some school districts approach to algebra high school failure rate of 50%.

Sincefirst curve, the teaching and learning of mathematics has always been a challenge. Developed over the past two decades, educational "technology" and have investigated the use of computers specifically for the teaching of mathematics. The need for a portable device for mathematical applications for development in recent decades.

The recent past has seen some advanced calculator created by leading manufacturers such as Casio and Texas Instruments, which are designed to provide specific applications have beenLearn mathematics.

Also offered to help TI handheld mathematical solutions to many challenges, such as teachers, students with the mathematical concept known problems in "real time" has had, and the chance to experience and explore concepts independently, as they are taught.

The availability of a ubiquitous technology, such as M-learning can play an effective role in teaching and learning of mathematics.

In Cellphonometry article ": Can kids really learnFrom the mathematical smartphone? "The writer details how to help schools successfully working with mobile phone companies to capture the math to children. The results speak for themselves.

Similarly, as an experiment by the National Taiwan Normal University conducted the ability to connect mobile student learning, the dots between mathematical theories and solve practical problems, and improved their attitudes towards learning mathematics.

The reason traditional mathematics is boringit is often because the lessons taught as numbers of a static page. Mathematics is an interactive self-subject, and students should be able to visualize and understand math concepts to understand. Mobile learning is the key.

Including video examples of data collection, animated graphics and packaging of mathematics education with a unique built-in media, mobile learning students are able to maximize the interactive nature of the technology to communicate effectively, whatever else a hard objectto learn.
