Learning trekking easier and cheaper with Moocs method

Difficulties of the trekking. Honestly and without grimaces.

It is necessary to cany a heavy backpack. The shoulders are gradually getting used to the load, but the weight is always pressing, especially when you are walking uphill. And it takes 6 … 8 hours a day. And tomorrow too…

Dirty, sometimes knee-deep, trails. Lying across the trail are trees. Stones and roots on the path and strive to turn your legs. Wandering cold rivers should be in shoes. The nights are cool and shivering, but there is nobody to warm it up. You can use best Police flashlight to get more light during the trekking.

Branches cling and tear clothes and body. The rains and the wind are ready to freeze you. The sun – are fry alive. And so it can be in turn for an hour.

To women: unwashed head, dirty clothes, no romance, no “comforts”, scratched hands and feet, men are mating, mosquitoes bite, and «no personal life”. And just hard! Loving nature happens in fragments, it is more necessary to look under the feet, so as not to roll your neck. And the leader-sadist again ran forward. Your head does not take into account your “logical reasoning”. Believe me, he knows better.

Positive sides. Well, not all is so “bad»…

It is so beautiful around only in the mountains. There, nature is untouched by civilization. Active outdoor movement is very useful. After the hike, it will be something new and interesting to tell friends, and then all the stories -about gossip and about “booze.”

There may be new Friends who have passed with you windbreaks, fords and passes. You understand that without a telephone and a TV7 you can live very much. You will learn a lot about yourself new. And good and not very … Something can be proud of! The physical form (in those who had it) is greatly improved.

I hope that these simple notes and tips can make your life easier during the hike.

And, accordingly, you will have more time to enjoy the wildlife. Unfortunately, the English – not my mother tongue. I maintain my notes in Spanish and Portuguese. Some notes may appear overly formalized, but that does not deprive them of their valuables.

A few simple rules in the hike

  • The leader of the hike is always right.
  • No one forced anyone to go on a campaign and even dissuaded.
  • Each participant carries his own backpack or goes home.
  • If the muscles hurt – it means they are, but it was possible to train better.
  • Collect firewood for the campfire all the participants of the hike, and not just the attendants. You can prepare some  best bipod for AR 15 to defense thief and beast.

Choosing a Shutter Speed

As settings are experimented with, such as with the three boardwalk images, it is important to remember the impact that adjusting the f/stop has on the results of an image. When it comes to low light photography, this is even more critical. Why? Because with low light there are many times when it is better to let more light in with a larger aperture, allowing for a faster shutter speed. With best high speed camera, you can have no worry about this.

When using a shutter speed of less than 250,1 highly recommend using a tripod for stability. This is even more true when there is a big, telephoto lens on the camera, as they add more weight, which can be tricky to keep braced. Shutter speeds faster than 250, with or without a tripod, will cut dowm on blurred images. There are times when a photographer intentionally slows the shutter speed in order to blur an image, like the headlights in this night shot. If that’s the case, then a slow shutter speed is called for. If the desired outcome is to freeze a moving object, then use a faster shutter speed.

While this may initially seem confusing, once these concepts are explored out in the field, they eventually become almost automatic.

Composition

It is rather amazing what humans subconsciously process when they view a photograph. Many have a simple knowing that a photograph (or painting) is composed well or not because much of it stems from what transpires in the connection between the work of art and the brain. In other words, we know what we like when we see it with best lens for canon 80D.

Composition also matters in every genre of photography—landscape, portraiture, street, journalism, fine art, etc. No matter the subject or the photographic event, if the composition does not resonate, the shot will be a flop. Alternatively, if the photographer nails the composition, the photograph will be a success. Understanding the Rule of Thirds

The foundational method of composition is the “ Rule of Thirds.” It is a simple enough rule that once understood, photographers can’t help but think about it when capturing an image. When it comes to composition, the Rule of Thirds is one of the first concepts amateur photographers should learn.

What is the Rule of Thirds? DSLRs have the option of displaying a typical nine section grid, such as this one. When this grid is displayed, it breaks the camera’s horizontal screen dowm into nine squares, equaling three horizontal and three vertical squares.

The concept of the Rule of Thirds is to place the subject in the top, bottom, left or the right third of the grid, also known as the frame. Breaking the Rule of Thirds is when the subject is placed smack in the middle of the frame. The idea is to split the image, such as this simplistic example of a bale of hay, into a 1:2 ratio (one third and two thirds), instead of in half.

One reason why this rule works is because of this: if a photographic subject is placed smack in the middle of the image, it is what artists consider static. In other words, the viewers’ eyes are drawn to the subject, but then have nowhere to go from there because the subject is placed in equal distance from all four edges. The eye is drawn to the middle and stays there, hence being static. However, when the Rule of Thirds is used, and the photographic subject is positioned on one of the edges, be it left, right, top, or bottom, it instinctively forces the eye to follow it. This, by default, allows viewers to linger on the photograph, which makes for a compelling photo because it becomes nearly interactive.

Take these three photos of the Jacksonville, Florida sunset as an example. Proven Theory

Photographers and artists use the Rule of Thirds because of its timeless and proven theory. However, we all know rules were written to be broken, right? Photography’s Rule of Thirds is the perfect example. In fact, if rules are meant to be broken, it would certainly be in the creative realm. With that said, a rule ought to be understood before being broken.

Many amateur photographers break the Rule of Thirds because they simply and innocently don’t even know it exists. Yet, a seasoned photographer not only abides by the rule, but knows best how to bend, twist, or break it.

3. Tripods

Bow Down to the Tripod

In photography, the equation is simple: shaking equals blurring. Hand holding a camera in low light increases the odds that the shot will be blurry. With a tripod, the shutter can stay open as long as needed—minutes and even hours, and as long the camera remains still, the picture won’t be blurry. Yet, too many photographers dread pulling out their tripod because they are clunky, and some are even downright heavy. They can be a hassle to carry around, especially when out in nature. However, by using a tripod it can make the difference between an amateur shot and an epic shot worthy of framing for hanging on a wall or at least a lot of likes on Facebook.

Steady at the Wheel Means Sharp Images . Simply put, the most compelling reason to use a tripod is to increase the camera’s stability. The last thing a photographer wants their camera to be is unsteady like a newborn colt!

Camera stability is what tripods were made for, and when stability’ is in place, razor-sharp images are more likely to happen.

Sadly, the extra bit of time taken to unpack and set up a tripod tends to discourage some photographers. Yes, it certainly does take extra time. Nevertheless, isn’t it better to ensure a selection of sharper images after all the time spent heading into the woods, fields, rivers, mountains, oceans, or wherever else a photography muse leads? The tripod will certainly help to avoid coming home with blurred images (and possibly a few ticks or mosquito bites, too).

Note that there will be times when Mother Nature can interfere, such as during high winds, which can obviously rattle a tripod and camera around a bit. In conditions such as these, further adjustments will need to be made.

Tripod Set Up and Two-Second Timers

Uncertain footing beneath a camera, which is commonplace in landscape photography, is to be expected. This is why tripods are built with a multitude of adjustments. To make the camera as level as possible, adjust the individual leg lengths to accommodate for ground that isn’t level. It isn’t uncommon for my tripods to have one leg up on a rock while the other two are in sand or dirt.

Once the camera and tripod are set, use the two second self-timer to ensure pressing the shutter button doesn’t shake the camera. To find out how to set the self-timer on your specific camera, check with the camera’s user manual or do a quick Google or YouTube search. The answer is bound to be out there, especially for current digital cameras.

Four Types of MOOC Research: From Fishing in the Exhaust to Design Research in the Core

To draw attention to these design considerations, in this presentation I will present a taxonomy of four kinds of MOOC research:
• fishing in the exhaust: post-hoc analyses of courses designed and taught without any particular research agenda, yielding descriptive, observational insights
• experiments in the periphery: A/B type experiments of particular pedagogical approaches that test domain-independent teaching strategies (e.g. commitment devices, priming experiments, or motivational messages) that can be conducted
• observations in the field: qualitative research from interviews and observations that seeks to investigate the contexts in which MOOC students learn and the ways in which they make meaning of their experiences
• design research in the core: design research conducted in partnership with course faculty, instructional designers, and learning scientists to investigate pedagogical questions that attend to core issues in the design of a learning environment (e.g. the effect of using block-based programming languages in introductory computer science courses).

The past year of MOOC research has been characterized by “fishing in the exhaust,” and while some useful initial descriptions of user behavior have emerged from these approaches, there are strict limits to what we can learn from observational research (even observational research with lots of data). The coming year of MOOC research will see more fishing, but also a growth of experiments in the periphery. These kinds of experiments are typically dreamed up by educational researchers and not by course faculty, and as a result they explore issues that are potentially interesting but not central to the learning goals of any particular course. These studies are easy to facilitate in the complex ecosystem of MOOC production, but they may not investigate the most important domains of large-scale online learning.

MOOCs and the Older Learner

Susan Hoffman, Chelsea Crown

The Osher Lifelong Learning Institute @ Berkeley (OLLI @Berkeley) is a year-round program of courses, lectures, special events, and interest circles for adults age 55+ through the University of California, Berkeley. Since September of 2013, our research team has been investigating Massive Open Online Courses (MOOCs) as a teaching and learning tool in lifelong learning. We have launched two small, informal case studies of MOOCs and the older learner. Our first investigation was specific to the experience of learners over the age of 80, the “high olds,” who enrolled in the Coursera MOOC “What a Plant Knows” and participated in three consecutive monthly meetings discussing their experiences. In January 2014, we expanded our investigation by holding a hybrid MOOC-classroom course, another Coursera course called The History and Future of (Mostly) Higher Education, open to all OLLI @Berkeley members 55+. Participants engaged in the MOOC in their own time and at their own pace during the week and attended 1.5 hour weekly classroom discussions to discuss the experience as well as content.

The MOOC learning experience of older learners is a crucial missing piece of the MOOC puzzle, an oversight in this era of profound demographic change. Concentrating on accessibility for older learners is important for many reasons, as this group may experience multiple barriers to MOOCs including challenges using technology, auditory and visual decline, and cognitive decline. However, this group may reap the most benefits from MOOCs, and thus deserve to be included in discussions. Given that the over 80 demographic is the fastest growing demographic in the country, as well as the most at-risk for social isolation, cognitive decline, and hearing and vision loss, the MOOC-as-intervention is an especially interesting concept to explore in further research. Potential benefits of MOOCs and the older learner may include advantages for homebound older adults who are able to remain intellectually stimulated and socially engaged as well as the neurocognitive advantages of continuing to learn stimulating new skills and knowledge, such as navigating technology and the multitude of subject areas MOOCs offer.

Common Pool Care Mistakes – Learn these tips online

You love swimming, you have a swimming pool in your house ? You may ask how to take care of your beautiful swimming pool so  you can enjoy swimming everyday.  If you say yes this article is for you :  3 Common Pool Care Mistakes.

Mistake 1 :  Not checking PH regularly

What is PH ? PH stands for potential hydrogen. The Ph is a measure of the percentage of hydrogen ions your pool water contains.  The lower the pH number, the more acidic the substance. The higher the PH number, the more alkaline the pool water contains. There is a scale of 0-14 for the PH number. Anything below 7 is acidic and anything over 7 is alkaline. What will happen if your pool is too acidic or too alkaline ?

IN THE FIRST CASE, YOUR POOL IS TOO ACIDIC :

Because acidic water is corrosive, therefore the more acidic the water, the more it will cost you time, money and the less pleasant you enjoy your swimming. It costs you the money and time because it causes the damage to your equipment, including : Pool filter and pump, Vinyl liner, Heater, Automatic cleaner, Chemical feeder, Maintenance equipment, Solar blanket. It makes your swimming unpleasant because your swimwear color will fade in acidic water over time and your eyes will sting and burn when you swim in a pool that is too acidic. Your skin will be ichy, tight and dried-out because the natural oil on your skin will be removed in the water with low PH.  

IN THE SECOND CASE, YOUR POOL IS TOO ALKALINE :

If the water is too alkaline, it can cause scaling on the pool surface and plumbing equipment and can cloud the water. Your eyes and nasal cavities will be stinging and your skin will feel sticky.

You may want to know the range of PH scale you should maintain and how to keep your pool’s PH staying in this range.

The ideal PH range is from 7.4 to 7.6. One thing you should know is the PH of your pool’s water can frequently change due to factors such as rain, sunscreen, sweat and evaporation. And here’re the ways to keep maintaining your pool’s PH :

Use proper test equipment and test your pool’s PH once a week

Make chemical adjustments.

Consider to call the pool service professionals for the instructions or any questions or the service if you don’t want to perform these tasks

Mistake 2 :  Not brushing your pool

To make your pool clean, we all know that we should use best pool cleaner and especially nowadays with the development of technology, we have the best robotic pool cleaner with extremely efficient cleaning ability. But you also need a pool brush to take care of hard-to-reach areas : behind ladders, the water line at the top of the pool, steps or stairs, corners and crevasses. Brushing the pool is easily forgotten and seems like an unnecessary and daunting task but it does need to be done weekly or more because the hard-to reach areas are usually not brushed well by an automatic cleaning system. Using a pool brush will reduce the chances of stains on your pool and further increase the cleanliness of your swimming pool. So how to brush your pool ? To brush your pool, use a nylon pool brush or you can choose a combination stainless steel and nylon pool brush. The bristles of the brush should be kept in good shape and not left in the sun. Attach the brush to your telepole and run it across the hard-to-reach areas. It doesn’t need to be scrubbed down with force, just a simple brushing along the surface is good enough.

Mistake 3 :  Common mistakes in using shock

Shocking your pool is a great way to remove organics in your water, kill off algae, and make your pool stay clean. Pool shock is either chlorine or non-chlorine chemicals that you add to the pool to destroy any contaminants in the water. The goal of shocking your pool is to raise the free chlorine levels to a point where it will destroy any algae or bacteria growing in the pool. The free chlorine is “good” chlorine that is still able to keep your pool fresh and clean. Here are three  common mistakes in using shock :

+Shocking your swimming pool during the day : You should shock your pool everyweek. It needs 1 pound of shock per 10.000 gallons of water. In order for your shock treatment to be the most effective, you need to shock your pool at night or dusk. You may ask why ? Because shock is un-stablilized chlorine. The sun will burn off 1ppm (part per million) each hour. To reach break-point oxidation, you need a chlorine level of 13 ppm or more. If you shock at night, the sun can’t burn off the chlorine and it will leave enough time to do its job.

+Adding pool shock through your skimmer :  When combining Pool shock and chlorine, it will create a deadly gas. If you have an automatic chlorinator attached to your filter system, and you pour the shock into the skimmer, the shock and chlorine will mix inside the chlorinator which can cause the chlorinator to explore. The explosion may hurt some people and this will be the biggest mistake you can make in taking care of your swimming pool.

+Adding shock directly into the pool water : if you add shock directly into the water and you have a vinyl liner in your swimming pool, the shock granules will sink the bottom and bleach out your liner. It will also cause the area to become brittle and frail which can cause leaks. You may want to know how to shock a swimming pool in the right way, here are the quick tips : always use gloves and protective eye wear, add 1 pound of shock a 5 gallon bucket of water about ¾ full, always add shock to water not water to shock, wear clothes you don’t care about because they might get bleached, warm water dissolves shock faster than cold, use a wooden stick and slowly stir in the shock making sure it dissolves completely, or as much as possible, slowly pour the bucket of pre-dissolved shock around your pool. You may have some undissolved shock at the bottom of your bucket. In this case, just dip your bucket in some pool water give it a slow swish around and pour it back into the pool to help dissolve some of that shock, do not mix all the bags together in one bucket. Shock should also be added every week to ensure a clean and algae-free pool

Bottom lines : To avoid the above three common mistakes, please check PH regularly, brush your pool with a pool brush, avoid common mistakes when shocking your pool. Hope you enjoy swimming after reading our online workshop.
