10 Ways To Help Your Child Embrace “Green Living” – Part 1 – SmartBean
Well it's actually a list of 5 (since this is part 1), but 5 really simply but effective ways to help your kids, even little ones as young as 4 and 5, become conscious of their eco-footprint and environmental issues. Raising our kids to be "green" is indeed one of best things we could do for plant earth - "the only home we've ever known" (Quote from Carl Sagan's "Pale Blue Dot" video - linked in the article - it really hits the spot...).

"21st-century skills", "21-century learning" "21st-century education", "21st-century learners"... These phrases are all around us. They even feature as themes in the SmartBean Magazine and Resources. What do they mean? What's different in this century? Why are they necessary? Who decides what these are and how they should inform K-12 learning? SmartBean hopes to answer these questions briefly.

What started as a germ of a idea over a year ago in this post titled - The Ideal Technology/CS Curriculum for Middle School and caught the eye of ISTE's Anita McAnear, editor of Learning and Leading with Technology (L&L) and national program chair of NECC, has now appeared as a full length article in the November 2009 issue of L&L. (Yes, it does take that long for the submission, review, approval, editing, and final publication process at L&L. I first submitted the article in November 2008, it was approved in Jan 2009, sent to me for revisions in April 2009, final edited version sent to me for review in August 2009 with a promised publication date of November 2009!!) Thanks Anita, ISTE & L&L!
Computer Science Not Just For Big Kids
It is sad more than surprising that computer science, which has been a bona fide discipline for over half a century now, has found little to no space in K-12 curricula. As a result, most students go through their school years naively equating computer science to simply computers or computer programming. As the Dutch computer scientist Edsger Dijkstra said, “Computer science is no more about computers than astronomy is about telescopes.”
Computer science is the study of the theoretical foundations of information and computation. Given the amount of exposure students get to the science of the physical, living and non-living world, it does not make sense to completely ignore a science that governs much of the technology and the nature of the “form” in which we transact information on a day-to-day basis in our techno-saturated lives.
In addition to a basic understanding of the essential definition of what computer science is, students can and should also get exposure to some of the foundational elements of the science of computing which gel well with the broader goals of 21st-century learning. These elements include algorithmic thinking, Boolean logic, functional abstraction, and data organization and management. Problem-solving, critical thinking, and information organization and management can be reinforced through delving into these aspects of computer science. The wonderful thing is that most of these concepts of computer science build on mathematics, and some of them on school-level mathematics.
The advantage of this early exposure to the fundamental elements of computer science is that it will give high school students who opt for courses in programming a more solid foundation of algorithmic thinking and data structures—the basic nuts and bolts of the mechanics of computer programming. Additionally, it will give students a better sense of their own interest in this field, supported by a better understanding of the science itself.
Here are a few ways to incorporate these concepts into the curriculum.
Algorithmic ThinkingSimply put, an algorithm is a well- defined set of steps required to complete a task. It is essential to understanding how and why information technology systems work as they do.
Detailed task breakdown is an important aspect of algorithmic thinking. In my robotics workshops, I usually devote a session or two to algorithmic thinking before I introduce students to programming. One fun exercise involves writing a set of detailed steps in plain English to guide a blindfolded student partner to perform a certain task. I often weave ideas of exception handling, iterations, and conditional actions into this exercise. Writing “pseudo code” in this manner also helps expose students to an essential skill that programmers often employ when they embark on a new program that requires them to think through the algorithm before they start to code the program.
Fortunately, we have access to programming environments that make it easy for teachers to drive these ideas home. For example, Alice (www.alice.org) is an excellent tool to support the development of algorithmic thinking, as is Scratch from MIT Media Lab (scratch.mit.edu). The visual feedback that students get from Alice and Scratch allows them to relate the program to the action they see on the screen and helps them refine their programs, an essential part of problem solving and programming. Earlier environments such as LOGO also helped achieve those goals in addition to allowing children to easily experiment with ideas of repetition, functions and subroutines, parameter passing, and even recursion.
Algorithmic thinking helps students make that step from problem to program. This involves being able to define and state a problem clearly; break the problem into smaller, more manageable subproblems; and describe the solution in a well-defined set of steps. . This is an important skill that students can transfer to problem-solving situations in other subjects too.
Boolean Logic for Critical ThinkingBoolean logic (or Boolean algebra) is a form of symbolic logic that is the basis of the arithmetic of computers. George Boole’s pioneering work in this field was published in the book An Investigation of the Laws of Thought, which describes how the logic of human thought can be reduced to a few simple, general, logical “operations” (much like the basic operations of mathematics).
Students can be introduced to the idea of logic in language arts or mathematics. Premises, conditional sentences, denials, and drawing inferences from sets of everyday sentences can form a soft introduction to the idea of logic even before introducing symbols and operations. Here is an example:
If the Giants beat the Dodgers, then the Giants win the pennant.
If he is out, then the Giants beat the Dodgers.
He is out.
What is the conclusion?
The beauty of Boolean logic lies in the simplicity of its operations: and, or, and not. When I was first exposed to the ideas of symbolic logic, I remember thinking that this was a mighty useful way for people of any age to learn how to think and argue logically as well as to find fallacies not only in political arguments but also in day-to-day arguments with parents, siblings, friends, and peers. This could certainly be one way to teach children to think critically and analytically.
Data Structures and DatabasesData structures go hand in hand with algorithms as an essential aspect of programming. Simply put, data is the stuff that is manipulated or worked on by operations and expressions in a program. To enable this process of manipulation, computer scientists organize this data in structures known as arrays, lists, trees, tables, stacks, queues and “heaps.” A database, similarly, is an organized collection of data, usually stored as records in tables.
Fortunately, we have access to spreadsheet software such as Microsoft Excel and database management software such as Microsoft Access that could be used to introduce students to the fundamentals of data structures for organization and management. Free or low-cost alternatives of such software are also available.
Spreadsheets can teach students how to organize data in simple, intuitive ways for easy access and retrieval. Children should be encouraged to use spreadsheets often and for a variety of data-organization tasks. For example, students could list and organize websites they visit for a school project or while researching a topic. Have students add keywords or tags to another column in the spreadsheet. They can organize the website data in separate worksheets for different units in a subject so that the organization helps delineate data that doesn’t necessarily belong together while still keeping related materials together. Spreadsheets can also be used for storing and organizing data for planning field trips or events, or for data collected in science or social studies projects. Google Spreadsheets allow several students to work on the same spreadsheet.
Teachers should also use spreadsheets to introduce students to the idea of sorting and ordering data. When does it make sense to sort or order data, and when is unordered data just as useable? Will sorting help future storage and retrieval? If so, how should the data be sorted? Such questions will get students thinking about the basics of organizing data in ways that make manipulation easy.
Students in middle school who have been exposed to spreadsheets could graduate to databases with a database management tool like Microsoft Access. Through the process of database design, students learn to analyze the information they are working with and identify the underlying dimensions of the content to organize it for meaningful search and retrieval. They learn to identify relationships between different types of data. Through the act of simple database querying, students can bring to bear their knowledge of Boolean logic and constructs such as and, or, and not while getting a sense of how the process of Internet search is conducted.
Teachers can get their students to engage in simple projects with clearly defined goals. A database that helps retrieve children’s books in the library by genre is one example. Such a project would require students to analyze the nature or elements of the data to be organized, design the database, populate the tables with data, and, finally, formulate and run simple queries. Database design also helps students build analytical, critical-thinking, and problem-solving skills.
At a time when we all grapple with a surfeit of data and information, being able to classify and organize it for sense-making as well as easy and intuitive access and retrieval is certainly a skill that children of this Information Age should develop early in school.
All three skills and concepts described above—algorithmic thinking, Boolean logic, and data structures— could be easily integrated into the elementary and middle school math, language arts, social studies, science, and technology curriculum, and would work well to expose students to a few basic ideas of the “science of computing.”

Ever wonder why Archimedes got his “a-ha” moment while lounging in his bathtub? Or why Newton unraveled the secrets of gravity while daydreaming under an apple tree? If recent research is to be believed, it may well be because the wandering mind is fertile ground for creative problem solving!
The findings of a couple of separate studies (finally) legitimize the preoccupation of choice for most of the human race – good old fashioned daydreaming. These studies focus on the type of activity that goes on in the brain during mental drift – a cognitive state that can occupy as much as one third of our waking lives.
One study reveals that when the mind drifts, the temporal lobes — which are associated with processing long-term memories — become busier. So when one floats off into a reverie, there’s some important data-storage work going on. Another study has reached an even more interesting conclusion – that the idling mind is likely doing deeply creative work, tackling hairiest long-term problems. This theory is supported by scans that have found that the wandering mind utilizes the prefrontal cortex, the part of the brain that’s involved in problem-solving.
So the next time you’re struggling to solve a complicated problem, you might be better off switching to a simpler task and letting your mind wander. And if you find your child indulging in some unfettered mind wandering, refrain from the usual “don’t just sit there daydreaming, DO something!” Who knows, that brain might just be addressing some knotty big-ticket issues.

"Although Lego dutifully sells a plethora of kits accompanied by detailed instructions for creation of specific and intended objects, which are becoming increasingly big - in size and complexity, the greatest benefit perhaps is to be derived from allowing children to be completely unburdened and simply indulge in open-ended and free format creation and construction. The result would most likely be experimentation that draws from the world around the child in what the experts call "constructivism" and "constructionism". Like these incredibly simple, creative and cute artifacts."

This is such an important issue that parents in India need to give some attention and thought to...Kids 13 and up are stressed out and burned out by the time finish their 12th grade exams and college entrance exams. Their lives for those 5 years is a blur of books and tutors, and extra classes and tests and exam prep. Help kids reclaim the joys of their teen years. Their health and happiness is at stake...this madness must stop!

Think you can watch videos, make cell phone calls and send e-mails all at once? Stanford experts say even trying can impair your cognitive control.
With many educators touting multitasking abilities of digital natives as a plus, where does this study leave us? Do you think 21st century skills should include learning to resist the urge to multitask and the ability to focus on a task in the face of a zillion distractions?

On Feb 3rd, Google launched the "Internet Bus Project". Simply put, this is a campaign to take the internet - quite literally on wheels - right to people in the smaller cities in India who are still not participating in what is now part and parcel of our lives in urban centers. The campaign has been launched in Tamil Nadu where the Bus will visit 15 towns in the next 45 days.
An interesting, and noble, aspect about this initiative is that the focus is the Internet and not Google, per se, as is evidenced by the videos that have been uploaded to the Internet Bus Google page as well as the internetbus channel on youtube (and are shown to visitors on the Bus as well). The video on "Internet for Communication" for example, shows facebook and Yahoo IM as means of social networking and communicating in the same breath as Orkut and Google Talk. Similarly, several sites and online services that work well to make day-to-day life easier for Indians - from online news (in Indian languages in addition to English) to cricket to matrimony to jobs to railways to e-gov - and are showcased in the videos, have nothing to do with Google.
Another worthwhile aspect being highlighted by the Internet Bus is the Indian-language Internet. Communication via the internet, as well as creation and consumption of content in Indian languages, such as Tamil, Hindi, and several others, is possible, but not a well-known feature among certain demographics in India, who perhaps view the internet as a service and convenience that can be enjoyed only in the English language. How many of us have visited the Hindi or Tamil wikipedia (which now has thousands of pages in at least 10 Indian languages, the highest number being in Telugu!)? [On a side note, this 'list of wikipedias' is an interesting page to study.]
The internet is being presented to the Bus visitors in 4 themes - Internet for --
With access (computer hardware as well as connectivity) becoming cheaper by the day, and more and more Indic content as well as Indic language tools being made available to Indians (by Google and others), it just does not make sense for the large percentage of Indians in smaller towns to not avail themselves of the affordances of the internet, and to remain marginalized from the global revolution that is the internet.
Go Google! Go Internet Bus! Go India!
Here's some press from the launch event in Chennai on Feb 3rd -

Kids today are often referred to as “digital natives” (an idea that has been described here and here on this blog). They enjoy being able to express themselves through the many digital technologies that they are so facile with; technologies that they would enjoy putting to use for the purposes of learning (and school work) as well.
This video was created to inspire teachers to use technology in engaging ways to help students develop higher level thinking skills and be better prepared to succeed in the century. It is just as important for parents to understand, and sync up, with their digital kids.
‘A Vision of K-12 Students Today’ was probably inspired by an earlier video ‘A Vision of Students Today‘ made by Michael Wesch in collaboration with 200 students at Kansas State University in which they share similar views (in similar fashion too) about their affinity for, and desire to use, digital media in higher education. This earlier post discusses Michael Wesch, his work on studying mediated cultures, and his popular channel on youtube.
In case you have not caught this on the news wire, India is all set to launch a $7 or Rs. 500 laptop. If India does manage to pull it off, it'll be quite a response to the OLPC $200 (originally the $100 laptop)!
"It forms part of the National Mission on Education through Information and Communication Technology, India’s new scheme to boost learning in rural areas through the internet." I do wonder about the fate of a project that has the Indian government behind it - I'd have bet on a private sector initiative to meet with better success, but there are some elite partnerships that are making this possible -
"The laptop is the result of cooperation between several of India’s elite technology institutions, including the Vellore Institute of Technology, the Indian Institute of Science in Bangalore and the Semi-conductor Laboratory that forms part of India’s Space Department. Private companies are also taking part."
Clearly, introducing a machine such as this and even flooding rural schools with it is not the answer to providing better education. The key is in training teachers and developing appropriate applications and curricula that will leverage this tool for better teaching and learning in the millions of classrooms that form part of the abysmal public school education system in India.
That said, I do hope that this machine makes it out the door - as a testimony to Indian engineering, if nothing else. Perhaps other details like the "how" of putting it to good use in classrooms will follow in due course. (I'm feeling strangely optimistic today :))
[Update: The spate of negative press that followed this news piece is disheartening, to say the least. It seems like the $7 or $10 was just a figure thrown up out of nowhere with no concrete details. See the links below. Even if it turns out that the government is hugely subsidizing this, I suppose it is alright, as long as in the end it is truly affordable for rural schools to use this....India could've done without egg on her face, though.]

The companion article in Science (requires a subscription to read the full text), which Dede says is "about a set of opportunities that a particular type of interface represents and the opportunities [it presents]," explores his research on the intersection of education and virtual worlds through HGSE projects like River City and Harvard Augmented Reality Project (HARP).
Research in education on immersive interfaces like River City and HARP could potentially have a profound impact on the use of video and other multi-user virtual gaming environments in the context of ubiquitous learning in the coming decades.
This particular podcast also covers a story on how a new home e-learning system is leveling the educational playing field in Korea.
