TI-Nspire Day 2 & 3

So my three day 18 hour workshop on the TI-Nspire CX CAS has ended and I wanted to write my comments about the calculator and what I learned.

Overall Quick Review
Pros: Color screen, JPEG support, CAS, USB still accessible with Navigator system attached
Cons: Not usable on tests, too small for its functionality, nothing new

Here's points that I wanted to talk about:


CAS: The calculator I chose to get was the CAS, which is a computer algebra system. When I was growing up we called this a symbolic manipulator, the same reason we couldn't use TI-89s was because of this. As of right now CAS is shunned upon since it isn't allowed for most testing, but it is a fun tool to use when exploring variables, limits and integrals. The presenter talked about the integration of CAS into the curriculum in Canada and that someday CAS may be accepted here in the states, but as for now this tool is primarily for demonstration purposes since students cannot rely on it for a variety of uses.

Touch pad/Click pad: It is definitely a neat idea, but whenever I am trying to use the clickpad it thinks I'm using the touch pad, or when I try to bring up my cursor it takes a while for it to recognize the touch pad use. I feel that this is more frustrating to use than it's worth. What I would really like to see is using that huge color screen as a touchscreen instead, but that may be on the next model.

Handheld: The first day of the workshop we used the handhelds exclusively and I was excited to learn the new calculator, and I did learn a lot about it. I also learned that it is very annoying to use. It's set up like a computer where it has a file system and a mouse, and your main folder is "My Documents." The set up is very familiar, but using it without a proper mouse (like I would on a computer), just makes the feature slower. The next day of workshop we started using the computer software/emulator which was infinitely better. The presenter kept saying that he wanted to hold us away from the software as long as possible because he knew we'd never go back to the handheld, and he was right. This drastic change in usability (and my attitude) makes me think that this device is just crossing the line in how powerful a handheld calculator should be and stepped into what a computer program should do for a student/teacher.

Scratchpad: Ever get caught up in a document and just want to do a simple calculation? TI responded to the urge of Nspire uses to use a different calculator to do simple calculations (e.g. pulling out an 84 or a 30) by creating a feature called Scratchpad. Just click on the scratchpad button and a temporary calculator screen that is independent from the document appears for you to do some quick calculations or graphing. I think this is a sign that there's just too much going on during the use of the handheld that should be on a computer which can multitask (the handheld cannot have more than one document open at a time).

Software: Manipulating pages, creating graphs, etc. is definitely easier on the software, especially if you are preparing a fancier document that has some coding within it to display certain properties. The software itself is amazing, my fellow workshop attendants say that software alone is worth the cost of the workshop (which was around $400). Now, I don't really believe that's true. It may be in some respects, but overall I wasn't impressed with that the software was doing since I have seen most of its functionality elsewhere.

Pages/Documents: The calculator allows you to make "pages," and there are different types of pages. There is a regular Calculator page to do what the home screen in the TI-89 and TI-83/84 do, which is fine. There is a Graphs page like the graph in the 84, but it will allow for editing. There is a Geometry page which allows you to do constructions to explore geometric concepts. In the previous Nspire Graphs & Geometry were the same page, which makes sense to me. They do basically the same thing, and it pretty much is Geogebra on a calculator. I would much rather have my students explore geometric concepts that can be done in Geogebra on a computer screen and not something smaller than an index card. Another type of page is Lists & Spreadsheets, which integrates the lists idea from the 84 and 89 into an Excel spreadsheet environment. You can do statistical analysis in here easier than in Data & Statistics. The Data & Statistics page is just Fathom. There is Notes, where you can simply type and type in math boxes to get proper mathematical syntax. The last page is Vernier DataQuest, which is simply a page developed by Vernier to interact with their probes.

Navigator System: When I first head of the idea of calculators connecting wirelessly to share files I was very excited. It is convenient not to hook up to calculators individually to send files, you can send to and collect from the whole class at once. The Navigator software allows for classroom management tools such as a seating chart, gradebook, sending out polls, sending/collecting files. There are ways to make a quiz and send the file to the students and have them self-check, or if the file type doesn't allow for that simply submit it back for grading. The software doesn't tell you who hasn't submitted yet if you are waiting on someone, or doesn't show who answered what. There is no feedback system where information  is sent back to the calculators with the student's grade and what was done incorrectly. All of these issues seem to be nonissues with SMARTboard software and their clicker system, which I feel is far superior to using a calculator as a clicker. Plus with the SMARTboard you get an interactive whiteboard. Now, you can use an IWB with Navigator, but I feel that it is unnecessarily redundant.

  If I were part of a school district and my department head sent me to this workshop to see if our school would benefit from investing in the new TI-Nspire, I think I would say no. I feel that the functionality of this calculator is great, but it would be better if the students had laptops and used the full-scale programs that are on the handheld. The laptop would also be a better investment because the school could then use e-books and cut the costs (and weight from backpacks) of rebuying textbooks. The laptop can be used to do research on the internet as well, which this device cannot do. The handheld costs roughly $175 (x30 for a class), and you need the navigator system to make it worthwhile so add another $2600. I don't know how much it would cost to get a class set of laptops, but I feel like it would be more valuable even if it cost more than $7850.

Tell me what you think! I have this calculator now and I definitely will try to use it, probably when I don't have access to my computer quickly, but otherwise what uses do you think it holds for the classroom that other cheaper (or even free) programs can do?

TI-Nspire Day 1

I am currently attending a summer workshop about the TI-Nspire CX CAS and its supporting teacher/student software. It's very exciting, let me tell you that! I am learning about the CAS system and basically how it can tackle various problems with greater formatting and understanding. Less ambiguity on a calculator is better in my opinion. We learned a lot, and I can see where it will come in handy this fall in Calculus II and my other math courses. I also got a classroom poster for the Nspire and a large binder with how-tos and student activities. Today was learning how to use the handheld and demoing the navigator (which makes the nspire definitely worth it), tomorrow will be learning the software and creating our own documents.

I met a lot of teachers from various areas in Texas, I am working in a group with an algebra/geometry teacher and a physics/chemistry teacher (just what will help me best!). I feel very edtech savvy with my smartphone and picking up the handheld device quickly. One of the things the presenter brought up during an activity that he said the nspire does that math teachers do not like is how it distributes over an equation, e.g.:


Instead of applying the operation to both sides of the equation, it simply puts the equation in parentheses and writes the operation once. Now, in all honesty this is the way that I do math by hand because I understand what's going on and it definitely saves me time, but it may be hard for students to understand what exactly is going on here. This is where algebra tiles or the algebra balance will come in to play in order to show that the operation must be applied to both sides (which is what the parentheses imply) in order to remain equal.

After the workshop let out for the day I drove around downtown Houston for a little bit. I want to see if there are any tours going on so I can make the most out of this trip. More on the workshop later!

#ntbootcamp: Storybird

Storybird is an online collaborative storytelling platform which is great for language arts and social sciences, but I have been struggling to find a use for it in a mathematics or science class. I decided to make an introductory story talking about tips for being a successful student in the calculus II course I will be working with next fall.


Tips for a successful Calculus Course From the Harvard Mathematics Department on Storybird

Other than the storybird, I am glad to be working with a steady group of students. This next semester's observations will be a little different too, I will be working at a school whose math program is promoting literacy in the classroom and I'm excited to use the tools I learned in my literacy course last semester. I have found that the things I learned in that class did help me in the past and has helped me in my previous tutoring sessions with other students.

#ntbootcamp: Voicethread part 2

I was reading through this presentation about uses of voicethread and I found some interested that I wanted to share. Here is the original presentation for you to view.


  1. Mystery Game: If you have ever played the Yes-No game or something similar, the students can be presented with an image and comments highlighting certain yeses and nos and they can comment back describing what they think the theme is (e.g. regular polygon yes-no game, or other mathematical themes)
  2. Ice-breaker: Students can use it as a "My favorite.." or other introduction tool and can comment on each other.
  3. Collaborative Projects: When students work together to make a presentation, they can use Voicethread to make the presentation (e.g. the syllogism project in geometry).
  4. Describing a problem: Using Polya's problem solving process or just explaining a topic in mathematics.
  5. Interpreting Graphs: Students can post comments and draw directly on a graph to show which part they are talking about. Allows students to collaborate to come to a better understanding.

I've changed the ideas a little more to be specific to my experience in the classroom and how exactly I would use voicethread so far. I look forward to learning more!

#ntbootcamp: Voicethread

I have worked with voicethread previously in my technology in education course at the University of Illinois, but going through the bootcamp's explanation of voicethread was more informative and I'm glad that I was able to do that. I decided to make a voicethread that employs problem solving of a calculus problem that also engages discussion between students. Here is my voicethread below:




I'm sad that I don't have a lot of time this summer to work on what I want to do, but in my free time I am always looking at twitter and learning new things, following new people. I see my growth as a pre-service teacher in the way that I think about lessons and integrating technology for all students, even those without access to a computer or the internet.

I am currently reading The Death and Life of the Great American School System by Diane Ravitch, and it's very interesting to read about the programs there were implemented in New York and San Diego that were basically high stakes testing. I am almost halfway through the book, so I will give a better review later. Anyone else have something to say about this book? What should I take out of it?

#ntbootcamp: Wordle and Tagxedo


Last night I ventured into the world of Tagxedo. I must admit it was less intuitive than Wordle to use at first, but I eventually got the hang of it. I want to make more Tagxedo clouds because of the shape functionality, I think it is way more fun and visually stimulating than a Wordle cloud.

I learned from reading the tweets for #ntbootcamp and reading some blogs of other teachers participating in the bootcamp on ways you can use word clouds in the classroom.


From Whitney @ Never Left First Grade:


- Print off Wordle in black and white and have students color words by category for science, math, and more.

- Small groups could brainstorm on a particular topic, create a Wordle & use to present to the other groups

- Use for the vocabulary at the beginning of a new unit. Make sure the words are only outlined or black and white. Brainstorm meanings and have the students color the word after the class defines it.


You can also use Wordle/Tagxedo for an introduction / ice breaker activity. You can have the students make their own wordle with words that describe their characteristics, personality, favorite things, etc. and can have them display it to the class through a VoiceThread. That would be a great day 2 activity since the students will need time to create and make a wordle their own way.


I'm excited to use it next semester in my practicum since the program I am with will be trying to increase content literacy in mathematics. Tools like the word cloud and other visual organizations of vocabulary and ideas are crucial to the success of the program.

New Teacher Boot Camp!

I'm participating in the New Teacher Boot Camp being held by Lisa Dabbs through Edutopia. I'm really excited to learn about the different tools. We covered Worlde and Voicethread briefly in my educational technologies course at the University of Illinois, but I want to explore them a little more. StoryBird and Wetoku were on a list of resources, but they were not really mentioned or explained. I hope these next few weeks really help.

I'm also currently participating in another boot camp, it's a fitness boot camp through the Austin Sports and Social Club. It's been rough, I'm almost done with week 3 out of 4. I hope to participate in it again the next time I'm in Austin, TX.

Since I'm in Austin this summer I will also be attending the TI-Nspire workshop in Houston! I'm really excited to be learning about the new technology in the classroom and especially getting teaching software. The school that I will be student teaching at is using the TI-Nspire, and I've never used one, so here's to learning!

As the summer keeps going on and the new school year starts, my blog posts will become better, I promise. They won't be just plain old reflections, I want substance and learning with this blog and I hope you find time to help this pre-service teacher build her knowledge base and her personal learning network.

Introduction Post

I'm starting a blog! More news later, I want to keep everyone posted as well as have a record of what I have done in the past.
