Celebrating Hispanic & Latinx Heritage Month
This project is a part of the Hispanic & Latinx Heritage Month celebration because
it supports a Latino teacher or a school where the majority of students are Latino.
Every day, in Calculus class, the first thing we do is take out our homework, notebook, textbook and calculator. Many questions can be done analytically and verbally. However, the graphing calculator has become a focal point in class since many problems now require a graphical and numerical approach.
I have been teaching Calculus to gifted students at my high school every year since 1993.
Many of my students take the AP Calculus BC exam each May and do very well. As a result, some of my students go on to major in Science, Technology, Engineering or Mathematics at some of our nation's top Ivy League and Technical Colleges.
I try to keep in touch with my students after graduation to see what professional and career goals they may have met over the years. I am happy to report that I have found that some of my students have gone on to become teachers, professors, engineers, doctors and scientists in their own right. I am very proud of my students, I am privileged to be their teacher and I have been blessed with the opportunity to help them fulfill their dreams.
This project is all about helping my students succeed in my class, in their college majors and in their chosen professions or careers to the best of my ability and to the best of their ability. Will you please help?
My Project
For as long as I can remember, we've been using the TI-89 Graphing Calculator. This calculator was state of the art in the early 1990s, but now it's time for a change!
The TI Nspire CX CAS is a more modern graphing calculator with several advantages:
The Nspire has a high resolution color screen making our graphs much easier to view, manipulate, color code, and label. Both the 89 and the Nspire include a Computer Algebra Systems aka CAS. This means that they can actually handle Algebra and Calculus expressions symbolically. However, the Nspire has many more such functions available. These calculators are actually programmable computers. The 89 uses a form of BASIC combined with graphing and CAS functions. The Nspire also has a new language called LUA which is perfect for GUI programming on the calculator. The Nspire is a lot like a laptop PC in that it has an operating system, file directories and several apps. Using these apps, we can save our work as documents.
The best technology for teaching and learning Calculus is a PC or Tablet running a CAS.
However, the TI Nspire CX CAS has many of the same features. Also, since the AP Calculus exam requires the use of a Graphing Calculator, using the Nspire will give us access to the best of both worlds. We can still solve problems numerically and graphically. However, now we can check all our work Algebraically as well. With the Nspire I will be able to prepare my students for the AP exam and for college too!
