DIY: TI-83 DRAW Function Tutorial

My video shows how to find the tangent line of a graph using DRAW function on the calculator. I have learned that it is difficult to find the tangent line without using calculator. Therefore, I made this tutorial to help students in finding the tangent line. To make the video, I used my camera and a TI-83 calculator. Below is the video:



What is edupunk? Edupunk is a way in which you teach and learn with a Do It Yourself (DIY) attitude. DIY attitude can be found mostly in college students. Some college students don’t want to go to classes every day, so why not have a DIY attitude?!?! If I miss one day of class, I will not be able to get back on track. I don’t depend on classmates for class notes because the way I understand notes, is different from the way they do.

Talk − Action = Zero

1-1=0. You cannot have talk without action and you cannot have action without talk.     Talk <–> Action.

Ed techs like to claim that the Internet represents a revolution in human communication, one with profound effects on how we produce, consume, share, and value knowledge.

The Internet is a way of sharing information with many people. If you don’t know something, the Internet is your best friend. Technology makes life better and easier.

Educational technology is the study and ethical practice of facilitating learning and improving performance by creating, using and managing appropriate technological processes and resources.

Technology enhances learning. Students will be more engaged and that is always a good thing. Students will love to work on technological devices during school.

One thing that I like about higher education is that you can create online spaces. Higher education will be known as the guardian of knowledge.

Some basic concepts of edupunk are: human interaction, sharing information, and teaching.

Educational technology will continue to be on the rise.

Edupunk and DIY Education

Although the word Edupunk seems weird, but the actual definition is something different from what I thought about it. Edupunk is basically teaching and learning through technology or also called Do It Yourself.

I like the idea of Do It Yourself. As Jim Groom and Brian Lamb state in their article:

 There are simply too many applications of open-source software, open content, and public-service teaching and learning practice to cover them all here.

This shows that Edupunk is a way of teaching and learning in openness. Long ago, the internet was only used as a search engine, but now its being used to connect the world. I believe that the best way to connect world is to find ways that can benefit people, which includes online learning.

Before, the idea of publishing was not that great, but now it is easy though blogging. As Jim Groom and Brian Lamb state:

Having signed up for a Gmail account, a user can publish websites with Blogger, manage groups and mailing lists with Google Groups, videoconference with Google Talk, write collaboratively with Google Docs, track topics with Google Alerts, manage syndicated feeds with Google Reader, share video with YouTube, post images with Picasa, and do whatever it is that Google Wave is supposed to do. We need not belabor the power and popularity of services such as Flickr, Facebook, and Twitter. All this incredible functionality is delivered in remarkably stable and user-friendly environments, and it’s available free of charge!

Google is an example of edupunk, where people can connect and learn many things by themselves.

I found this interesting Blog on Edupunk that explains what an Edupunk really want.  I like the following quote An edupunk is someone who doesn’t want to play by the old college rules, which is something I totally agree with.

I am also one of those people who want to save time from traveling around and rather sit in one place and connect with others to learn. I love online classes. There are many students around who need to work to survive and also come to college to learn. By the time, these students get to school, they are tired and they are not able to focus on the learning in class. I think that online education can be really helpful in this type of situation. If these students can use DIY technique or through Edupunk, they can benefit themselves by both working and learning at the same time.

Down the Edtech Rabbit Hole – Conversations and Cursing about Edupunk and DIY Education

Reading Jim Groom and Brian Lamb’s article Nevermind the Edupunks; or, The Great Web 2.0 Swindle is what started it for me. It’s not the beginning, as there were links and networks that brought me to this article – working with e-portfolio at York College and the CUNY Academic Commons are two. But this article lead me to start following a hyperlink trail that lead me to read George Siemens, Leigh Blackall, Stephen Downes, Tim Berners Lee, Seymour Papert, David Foster Wallace, Mark Weiser, Jay Rosen, Gardner Campbell, Clay Shirky, Dave Cormier, Andy Carvin, and this was the beginning.

From there I discovered ds106 and leaped into yet another rabbit hole. One that has helped me become more productive than I have in years – creating art, teaching new ways, building spaces, and most importantly making relationships with people I truly am excited to engage on a daily basis. I’m so lucky to have found these people online and connected with them and believe it’s literally changed the trajectory of my career as an academic – all in about a year and a half’s time.

I don’t know if this is what will happen to you, or what exactly you’re looking for as you prepare for your future career in education. And this course on using educational technology is only a brief time on your path to getting there. You may believe that this course should be about learning how to use technologies that will change education, and we are lucky to be in a time when we can play with a lot of digital tools cheaply and easily which can truly affect a classroom. But I want you to think about this quote from Jim Groom from the blog post in which he introduced edupunk. He’s responding to a particular LMS company’s advertising that their product will “enhance critical thinking skills” and “improve classroom performance.”

These things are not done by technology, but rather people thinking and working together. Our technology may afford a unique possibility in this endeavor by bringing disparate individuals together in an otherwise untenable community, yet it doesn’t enhance critical thinking or improve classroom performance, we do that, together.

The idea that we cannot replace the person that is teaching and the students connections with one another with technology is an important one. There is so much we can teach ourselves, and learn from the rich resources of the Internet. But the connections with others online with which we can share and engage provides can be what we really need to strive for. Is it the technology or the community that matters most.

The conversations and cursing you might find about DIY Education and Edupunks can be a case-study on this particular issue of tech vs. community vs. the innumerable other lenses through which people are (re)envisioning these ideas.

So for your next blog post start with the Groom/Lamb article linked at the top and see where it and your journey through articles, blog posts, videos, images, etc. takes you. Quote, embed, and/or link to as many of the pieces you find that strike you. Give your perspective on what edupunk and DIY education looks like or means.
