A Step-by-Step Guide to the Best Projects - Edutopia ~ by Mariko Nobori

A Step-by-Step Guide to the Best Projects - Edutopia ~ by Mariko Nobori | STEM Connections | Scoop.it
We followed a sophomore world studies class through a three-week project called Controlling Factors, created by teaching partners Mary Mobley (English) and Michael Chambers (world history). They designed a project that capitalized on the wild popularity among their students of the best-selling novel The Hunger Games. Built on specific English and world history state standards, the project covered concepts including the pre-World War II global economic crisis, the rise of totalitarianism, and the societal moral dilemmas that world leaders at that time faced, and then had students draw parallels to similar fictional themes in the book.

Here is a breakdown of key steps, with some examples from Mobley and Chambers's project:

Sample Student's curator insight, May 24, 5:21 PM

The project based learning approach is another PBL - the same acronym as Problem Based Learning. Are they the same thing? Read Edutopia http://www.edutopia.org/blog/pbl-vs-pbl-vs-xbl-john-larmer for explanation. But the key message here is authenticity, meaning, complexity, learner-centredness, cross-curricular thinking, and collaboration. These are key pedagogies that are relevant to any discipline area. Although this may be focused on History and English, there are lessons to be found within this article that are relevant to any discipline area. It is an excellent informing article for everyone in our group.

The Oregon Trail Generation: Life before and after mainstream tech

The Oregon Trail Generation: Life before and after mainstream tech | STEM Connections | Scoop.it
We’re an enigma, those of us born at the tail end of the '70s and the start of the '80s.
Bonnie Bracey Sutton's insight:

We’re an enigma, those of us born at the tail end of the '70s and the start of the '80s. Some of the “generational” experts lazily glob us on to Generation X, and others just shove us over to the Millennials they love to hate — no one really gets us or knows where we belong.

We’ve been called Generation Catalano, Xennials, and The Lucky Ones, but no name has really stuck for this strange micro-generation that has both a healthy portion of Gen X grunge cynicism and a dash of the unbridled optimism of Millennials.

A big part of what makes us the square peg in the round hole of named generations is our strange relationship with technology and the Internet. We came of age just as the very essence of communication was experiencing a seismic shift, and it’s given us a unique perspective that’s half analog old school and half digital new school.

Eden Eaves's curator insight, May 24, 2:28 PM

Almost 80 percent of Americans live in urban areas and that means many people are wanting to grow their own food in the busy city life. To learn how to properly do this, these people turn to land-grant colleges and universities to give then helpful advice. Many colleges do help with urban and rural ares, but there is only one one in the entire country that is devoted singularly to urban farming; The University of the District of Columbia.

This is a great example of the distribution of agricultural and a great way to educate people on the proper way to cultivate and harvest your own food in small, limited spaces. It also proves that we really can prosper everywhere with the right tools and knowledge about urban farming.

Seth Forman's curator insight, May 26, 6:30 PM

Summary: This article goes into extensive detail about urban agriculture and new technologies and techniques that must be brought to urban agriculture.

 

Insight: This article relates to unit 5 because it talks about a new and modern form of agriculture that could become very important when considering the portion of the population living in urban and suburban areas. 

Michael Amberg's curator insight, May 26, 10:20 PM

This could help develop sustainable communities and promote organic growth throughout the country. Which could potentially improve the standard of living

The Precision Agriculture Revolution

The Precision Agriculture Revolution | STEM Connections | Scoop.it

"Thousands of years ago, agriculture began as a highly site-specific activity. The first farmers were gardeners who nurtured individual plants, and they sought out the microclimates and patches of soil that favored those plants. But as farmers acquired scientific knowledge and mechanical expertise, they enlarged their plots, using standardized approaches—plowing the soil, spreading animal manure as fertilizer, rotating the crops from year to year—to boost crop yields. Over the years, they developed better methods of preparing the soil and protecting plants from insects and, eventually, machines to reduce the labor required. Starting in the nineteenth century, scientists invented chemical pesticides and used newly discovered genetic principles to select for more productive plants. Even though these methods maximized overall productivity, they led some areas within fields to underperform. Nonetheless, yields rose to once-unimaginable levels: for some crops, they increased tenfold from the nineteenth century to the present.  

Today, however, the trend toward ever more uniform practices is starting to reverse, thanks to what is known as 'precision agriculture.' Taking advantage of information technology, farmers can now collect precise data about their fields and use that knowledge to customize how they cultivate each square foot."

Development and diffusion of agriculture-

This article explains how agriculture has developed and grown for thousands of years, and today with our technology, we can do what seemed impossible to the past peoples.

This article represents Development and Diffusion of Agriculture by showing how in our past years, we could mostly only do substinence agriculture, but today with technology, we can do so much more, with so much less people.

Land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts-

This article explains how today we have the best technology we have ever created agriculture-wise, but with this, more land has been used. But thanks to precision agriculture, we can use data to determine where we can use the least amount of raw materials needed, thus helping protect more land than before.

 This article demonstrates land use/land cover change: irrigation, desertification, deforestation, wetland destruction, conservation efforts to protect or restore natural land cover, and global impacts by showing how with the technology today and precision farming, we can use less raw materials than ever before, thus helping lessen global impact.

How Suburban Are Big American Cities?

How Suburban Are Big American Cities? | STEM Connections | Scoop.it

"What, exactly, is a city? Technically, cities are legal designations that, under state laws, have specific public powers and functions. But many of the largest American cities — especially in the South and West — don’t feel like cities, at least not in the high-rise-and-subways, 'Sesame Street' sense. Large swaths of many big cities are residential neighborhoods of single-family homes, as car-dependent as any suburb.

Cities like Austin and Fort Worth in Texas and Charlotte, North Carolina, are big and growing quickly, but largely suburban. According to Census Bureau data released Thursday, the population of the country’s biggest cities (the 34 with at least 500,000 residents) grew 0.99 percent in 2014 — versus 0.88 percent for all metropolitan areas and 0.75 percent for the U.S. overall. But city growth isn’t the same as urban growth. Three cities of the largest 10 are more suburban than urban, based on our analysis of how people describe the neighborhoods where they live."

Sammie Bryant's curator insight, May 27, 12:07 AM

This article accurately depicts the difference between a normal city 50 years ago and a city today, as well as the continuing spread of suburbanization. For example, Austin, the capital of texas, a hustling, bustling always busy area, is predominantly suburban. As cities and countries continue to advance and develop and its citizens become more successful and family oriented, suburban homes for families will become more needed than something smaller, like condos or studio apartments. As the needs of the cities change, the structure of the city changes as well. This applies to our final unit of APHUG: Cities and Urban Land Use.

Science Just Discovered Something Amazing About What Childhood Piano Lessons Did to You

Science Just Discovered Something Amazing About What Childhood Piano Lessons Did to You | STEM Connections | Scoop.it
If your parents forced you to practice your scales by saying it would "build character," they were onto something. The Washington Post reports that one of the largest scientific studies into music's effect on the brain has found something striking: Musical training doesn't just affect your musical ability — it provides tremendous benefits to children's emotional and behavioral maturation. The study by the University of Vermont College of Medicine found that even those who never made it past nursery rhyme songs and do-re-mi's likely received some major developmental benefits just from playing. The study provides even more evidence as to why providing children with high-quality music education may be one of the [...]

I especially liked the observation that schools that deprive most of their students of studying music or the arts are depriving them of much more than simply not learning an instrument - it is depriving them of a good way to developed executive function for one thing. -Lon 

Ivon Prefontaine's curator insight, May 24, 10:47 PM

I think having to concentrate the way a person does to learn scales and music helps children focus and be mindful.
