Ener. Consumption Research Project Update
I have successfully gathered the data cataloging the energy use involved with making hot beverages for one week at the school. I used my 1500 watt, electric water kettle for a total of 14 times for a total of 71 minutes of energy consumption. Then I calculated the total Kilowatt hours with the cost of this use. The going rate is 20.95 cents/Kwh.
While researching other brands of insulated electric kettles, I discovered a similar study to mine at deathbike.net : Electric Kettle Land. It offered some comparisons of a UK 3000 watt electric kettle, a similar kettle to mine, an electric range and gas range. The study compared the energy used to boil 4 cups of water by each heating source. Since my average consumption was near 4 cups per day, I was able to use the information from this study for comparative analysis.
I used the information for the UK 3000 watt kettle and the time to boil 4 cups of water and plugged in the data I collected for my study. I also made the calculations as if the kettle were insulated and only had to be used once to heat water for the day. I then projected the difference in use for one year, 10 years, and for 1500 people over a 10 year period. The difference was near 1 million Kilowatt hours for the 1500 people over 10 years and a money savings of close to $200,000.
Some of the most interesting information I found in my research was how much energy could be saved if you don't already use an electric kettle instead of an electric or gas range. This is one of the questions I raised for further study. Another question I focused on was if you already have a functioning un-insulated electric kettle, is the energy conserved by buying a new insulated kettle equal to the amount of energy used to make the new kettle?
The results of this study and the comparison numbers are included in my power point presentation. Also, included in the power point are websites for high quality electric kettles and additional information on energy efficiencies of electric kettles.
Unfortunately I am experiencing some difficulty uploading my power point point presentation to Slideshare.net but I as soon as I am able to do so I will post the link to access it.

Article Summary #2: "The Educators Guide to the Read/Write Web" by Will Richardson
Overview:
"The Educator's Guide to Read/Write Web" by Will Richardson introduces and outlines the recent evolutions of the web and how new tools can be utilized by teachers and students for class work. The author of this article explains how the internet is no longer a resource solely for the purpose of collecting information. The development of online tools such as weblogs, wikis, Really Simple Syndication (RSS) and podcasts also allow people to post ideas, ask questions, collaborate info and publish research to a much broader audience.
Collectively, these new tools make up the Read/Write Web and together they offer students new ways to access and share research results, collaborate with fellow students and professionals, and document class work. For teachers it offers new ways to deliver content and assess understanding. These new advancements may also mean that educators need to re-evaluate curriculums and redefine what it means to be literate.
There are, of course, some risks to consider when students are publishing personal works to such a broad, public audience and searching through content that has been freely published online. However, with proper oversight, instruction including appropriate use, and developing students' skills in recognizing legitimate information, results in the benefits outweighing the potential risks.
Reference Points:
1. "The internet is no longer simply a place where digital learners consume information. It is now also a forum through which users can publish and broadcast their own writing."
2. "Weblogs or Blogs enable anyone to create a personal or group Web site... publish text...hold online conversations...collaborate.... contact professional mentors."
3. "Wikis are an even more open and collaborative content creation tool....It is a Web site that anyone can edit at anytime....for the purposeful work of negotiating and creating this accurate online resource."
4. "Really Simple Syndication (RSS) enables people to subscribe to various feeds of information--data that are continually streamed and collected into a file. A student... can
create RSS feeds that will bring him or her the latest research on the topic almost as soon as
it is published."
5. "Now that anyone with an Internet connection can publish and disseminate content with no
editorial review process, consumers of Web content need to be editors as well as readers."
6. "Literate Internet users need strategies for sorting out, storing, and using relevant
information."
7. "As more content becomes available online, it becomes less appropriate to rely an
traditional curriculum delivery methods like text-books and handouts."
8. "Digital tools allow students to easily work together outside school--for example,
collaborating on projects through instant messaging or text messaging on phones--and to
share the results of that work with a broader audience."
9. Teachers employing these tools must monitor student use and teach students how to use
the tools safely to enhance learning. We must also show students how to deal with
inappropriate content..."
Reflection:
Although I am familiar with blogs and wikis, I found the additional information about how these tools could be utilized in the classroom. I especially like the point made by the author on how a blog can serve as students portfolio of school work, allowing the student to reflect on past work and see the progression of their learning. The information on RSS that was presented in this article is also very useful. This is a new tool for me and I look forward to using its research potential in my science classes.
Not being very technological savvy myself, any advice I can get on how to incorporate technological tools into my classroom is very welcome. Upon reading this article I have come to various conclusions on how I can do this. For example, Blogs may be an excellent way for students to report on long term research projects, such as science fair projects. It also allows me to comment on their work and offer suggestions one on one when time to do this during class can be very limited. Students can also use the RSS in order to help sort through the vast amount of information on the Web and maximize their research time.
I found the most important points of this article to be the need for students to understand how to be skeptical of posted information and how to determine what information is legitimate and relevant to what they are researching. One of the most important skills for a scientist, or anybody for that matter, is to be able to identify bias and misinformation. By teaching students how to weed through the content on the web in this manner, it can only raise the quality of their work and in turn make their results, trustworthy and legitimate.

Energy Consumption Research Plan: Insulated vs. Un-Insulated H2O Htr
Being that I live in cabin in the next valley from Skaway, without running water, and wood stove and with an electric bill of only $30 dollars a month the "classic" studies of energy consumption and how I could reduce my usage would be difficult for me to gauge. I could find out how much gas I would save if we biked to town but this is not something that is feasible for us to implement. As a result, I have decided to research my current use of an un-insulated water heater. Approximately 3-4 times daily I use my water heater to make Vietnamese drip coffee and other hot drinks while at school. The question I would like to answer is how much energy would I save if I purchased an insulated water heater that would keep water hot for hours instead of having to heat water each time I would like a hot beverage.
The data needed to complete this study is my estimated weekly use of my current method of heating water. In order to do this I shall record the number of minutes the water heater is in use. I would also like to determine what the energy consumption in kilowatts per minute of my particular water heater model. In addition I will record the average amount of hot water I use per day to determine what the optimum water capacity for a new water heater would be. After this data has been compiled I will compare it to the factory specs of an insulated electric water heaters with a water capacity close to my daily hot water consumption.

Article Summary #1: “Listen to the Natives” By Marc Prensky
Overview:
This article introduces the idea that many educator and educational systems have become “immigrants” in the digital world that has surrounded us in 21st Century. The “natives” of this new world are the students, who have by raised by the recent advances in technology and they offer a wealth of digital information for educators to take advantage of.
Outside of school modern students are inundated with technology and digital tools. Advanced features on cell phones, video games, and means of digital communication and information gathering are a part of everyday life for these “digital natives.” As a result, the classic means of educating our students are no longer as effective. In order to make school more meaningful and productive, educators must incorporate these digital tools into the curriculum and help students to take advantage of these digital tools to educate themselves.
Because the students in this new digital world evolve just as fast as the digital and technological tools around us educators must listen and learn from the students. The students can teach us what digital tools we should incorporate into the classrooms and how to use these tools to streamline the educational process. Many digital tools, including cell phones, can connect the student to the classroom from anywhere. They can also connect the student to any classroom around the world and by utilizing these digital tools we can enhance the student’s education in every aspect of their lives.
Reference Points:
• “Teachers must take time to learn what the students know and how they learn.”
• “Teachers should use students as a resource. Students can teach the educators what technological equipment should be in the classroom. And in turn, educators need to teach students how to take full advatage of the digital tools they have access to in their everyday lives.”
• “Students should be engaged the 21st century way: electronically. Content can be offered to students in the form of electronic games, known as “gameplay.” It offers students goals and immediate feedback as to how they are improving. It is also an interesting and interactive way for the students to learn material.”
• “Instruction must be flexible and adaptive to the digital tools available. One on one education with the students should be incorporated as much as possible and the creation of virtual groups and learning partners allows students to pick who they learn with.”
• “To prepare kids for their 21st century lives, we must help them maximize their tools by extending their programming abilities.”
• “Schools must find a way to integrate the student’s technology rich out of school lives with their lives in the classroom. If responsibility is instilled in the students, even cell phones can help accomplish this goal.”
• “Teachers must listen to the students, value their opinions, and make changes based on the valid suggestions they offer.”
Reflection:
I enjoyed learning a new way to look at my own “digital accent.” I have spent most of my life learning about the world around us, not the digital world. I appreciated the view presented in this article that due to this digital world kids today are being raised in, it is very hard to keep up with the students technologically. As a result, we should embrace this fact and utilize the student’s knowledge to enhance the classroom experience to better fit the students. I can also see how this would give the students more ownership in their education.
Just the other day I was asked if we could set up a way for students to more of their school work online or from outside of class. This would be very beneficial for traveling students or for sick students to keep up with the daily activities. I believe this is the type of “streamlining” that was mentioned in this article and one of the ways students can help the teacher.
I like many of the ideas presented in this article. Especially the “gameplay” method of instruction and assessment. With today’s gamer society this could be by far and away the most engaging educational tool. Of course it all comes down to time, which can be very limited, but the sooner we learn how the incorporate these digital tools the more interested our students will be in school.

Skagway School Districts Technology Culture
In order to complete the anthropological assessment of the technology culture within the Skagway School District I utilized information from multiple sources. Most of these sources were human. Including members of the Technology Team, the Administration, the Technology Teacher and the District Technology Coordinator.
The Skagway School District has a wide variety of hardware and software available to both teachers and students. The district has also had an ed tech plan and adopted standards and competencies for students since 2006 which they are currently in the process of updating.
Overall, the technology culture in the Skagway School District is advanced and progressive. To view the complete technology culture report for visit: http://docs.google.com/Doc?id=dd27wcjr_0d539cffc

FUTURING
FUTURING
A: How would I “grade” or assess Fox Becomes a Better Person and School Train?
If the only criteria for the for the assignment that spawned School Train was to exhibit an understanding of metaphors, Glen Bledsoe’s 4th graders did very well. Amongst all of the editing and video effects there were some very clear examples of the metaphors the class used in comparing classrooms to trains.
Some examples of theses metaphors presented in School Train are:
==> Students = Passengers
==> Classrooms = Train cars
==> Homework = Tickets
In regards to Fox Becomes A Better Person I am curios as to what the exact outline or objective for the assignment was. If they objective was to supplement a spoken story with visuals of the scene as interpreted by the storyteller Hannah did a pretty good job. Her pictures were obviously her vision of what was happening and there was time spent on her part to create them. They followed the story moving along and changing as major pieces of the story did. Additional pictures to help supplement the final events of the story were the only pieces missing. However, since she had already helped “paint” the picture for the scene at the turtle’s, the little bug’s, and the little duck’s house it is easy for the viewer to create these scenes on their own.
B: What impacts could the developments portrayed in Epic2015 have on your classroom, particularly with respect to the things like podcasting?
My largest concern for the impacts of the developments portrayed in Epic2015 would be how media as we know it today being dissolved into one provider, warping into a personalized filter for what you want to know or learn about as determined by a computer. Would this change in the media resource polarize the thoughts and opinions of each student? Not allowing them to learn about other points of view without having to actively search them out.
Another question is: How would this media resource affect research projects? On one hand it may facilitate research, making it easier to complete your research, but would the material be as reliable. How would you determine the credibility of the resource for the obtained information? As the teacher, it may take much more time helping your students find and determine what is credible.
Bringing us to Podcasts. Anytime someone is able to broadcast or publish any type of media the issue of privacy and confidentiality of information has the potential to become a problem. How would the students use this technological power? It could of course be used to spread rumors of false information about others. If this were to happen it could dramatically affect some of your students education because of what was happening in their personal life and everybody had the opportunity to know about it. On the other hand, Podcasts could be an incredible assessment tool. Instead of a test or written report students would be able to put information into a verbal report or organize it into a discussion forum or interview. This would not only be a tool for teachers but it could create new relevance and pride in the assignments by the students. This would be the result of the assignment not only being for the teacher and but it would let the world know what they were doing and what they believed in or stood for.
C: How might you use Sabrina’s piece as a model for something you would do with your students?
I really enjoyed SabrinaJourney. I felt it was put together very well and clearly expressed where and how Sabrina got to be where she is today. This could be used in many interesting ways in the classroom. Students could use this timeline narrative style to express > What they would like to do in the future > How their education has changed over the years leading up to this point > What they would like to get out of a particular course to prepare them for the experiences the future may hold for them.
There are many topics that could be expressed in such a project but I particularly like the idea of using it as a way for students to express what they would like to get out of their education. It would let teachers know what is important to their students and would give the students some ownership in the education they are receiving.
