Is Online Learning for Me

The year may be coming to an end for schools and universities but to many of us in the education game that means very little thanks to online learning. What it does mean is that we have more time to prepare and that goes for students too. The SATs will soon be a distant memory while school books will find their way into the bottom of wardrobes and drawers: lost, forgotten and in some extreme cases destroyed in a fit of ecstasy. But what if you had done the majority of your study and note taking online? Go you, those notes have remained safe and intact.   While your classmates or colleagues search frantically for their scrunched up notes, you’re conducting a simple login and click and voila, everything is right where you left it. This is the current situation for many students and teachers across America. Paperbacks and pencils are being replaced by tablets and keyboards. If you are one of those then hello, if not, let us show you how you can benefit from online learning. It doesn’t matter if you are studying for the SAT, the ACT or a graduate exam. Heck, we even have professionals using online platforms for their continuous assessment. But it’s not all about just learning; it’s also about collaborating, sharing, creating and inspiring. As I mentioned, the summer time has traditionally been known as a time when books get closed and the brain switches off. However, people are without a doubt becoming more driven and competitive. Many want to get a head start on their upcoming semester or work year. They may have employment plans or opportunities. There may be ideas afoot to go travelling or, worst case scenario, there may be test repeats. Either way, each of these scenarios share something in common: the need to learn over the summer months. While some schools, tutors and other sources of learning shut up shop, online learning remains open 24 hours   a day seven days a week 365 days a year. In the next 5 points, I am going to show you how online learning can benefit you. By the end, if you think it’s something that is for you, your next stop should be Magoosh for exam experts and ExamTime for the free learning tools. Happy studying folks: 1. As we mentioned, online learning allows people to study almost anywhere and at any time. Gone are the days when websites were poorly optimized and took an age to load. Now, as test day approaches you can be flicking through flashcards as you sit on the bus, you can be chatting with tutors in a safe online environment. The walls of limitation have been pulled down and you can learn around the clock. 2. Collaboration has multiple benefits. While tomorrows workforce are still at school and university, who said they can’t be engaging in activities that will make them great team players? Online learning once again provides that opportunity in the form of sharing and collaboration. Study groups, tutorial rooms and forum discussions allow students to voice their opinion on a subject, ask for assistance, and exchange notes. Traditionally if someone needed assistance with something after hours, they would have to wait till the following day for that help. Now, thanks to the likes of Magoosh and ExamTime, those answers can be obtained online through groups and hangouts. 3. Bar a power outage or your mobile/ table battery running flat, access to your notes, results, questions, tutors, peers and study aids is readily available. A weekend away or an unforeseen event shouldn’t mean that your material is not at hand. We are all guilty at some point in life of forgetfulness but with internet access being so readily available—you guessed it—so too are your notes. Just get online, log in, and your notes are ready to go. 4. While students may think they are simply going through the motions of a teacher’s request, they are in fact learning key skills that are equipping them for a future in our workforce. The simple act of using a keyboard, surfing the internet, creating and saving files, creating study plans and seeing that they are executed on time are all activities that are representative of what will be required of them in later life. Developing teamwork skills through project collaboration and allowing creativity to take over are abilities that traditional methods of learning did not always provide. 5. Finally, the trust factor. Our students are always maturing but even the simple process of allowing them to engage in online learning enhances that progression.   They are presented with the opportunity to display real accountability and trust. However, thanks to cutting edge tracking and monitoring tools that the likes of ExamTime offer, tutors and teachers are always on hand to make sure everything is running safe and smoothly. If you engage in online learning please let us know how it benefits you. If you don’t currently use online platforms for learning, would you consider it and what are your reasons for not using it?

Slavery And The Reconstruction Of The United States

In addition to the Europeans being criminals by inflicting pain and suffering, and doing horrific things to the Natives; we will now go to the crime that occurred to during slavery and the reconstruction. Like mentioned before, there have been many different ways that crime has been committed since the beginning of The United States of America. One of the very first crimes that were committed in America, was when the European settlers arrived to some land what they thought was the sub-continent of India but was actually now known as America, and labeling the indigenous peoples as savages, as the Europeans killed many of them off while trying to assimilate them. During the year of 1619, one of a few crimes that were committed was when the Dutch brought some of the first captured Africans to America, in which eventually changed what is now The United States and what it now stands for today. Although slavery was not documented and considered as a crime, it was a form of forcing individuals to produce hard labor against their will. The techniques of controlling the slaves were many and varied, and brutal. There were also laws set in place that helped with the control of slaves called Sla ves Codes. Slave codes were defined as laws that defined the low position held by slaves in the United States.

Although these statistics are alarming, there are a number of treatment options available for those that are diagnosed with breast cancer. nbsp;nbsp;nbsp;nbsp;nbsp;The best way to treat any disease is to prevent it.

Radiation involves the use of high-energy x-rays to damage cancer cells and retard further growth. The radiation may come from a radioactive source outside the body, or it can come from radioactive pellets placed directly in the breasts. It is not uncommon for a patient to receive both internal and external radiation. For external radiation, patients must visit the hospital or clinic each day. When this regimen follows breast-sparing surgery, the treatments are given five days a week for five to six weeks.

Renaissance in the tempest Essay Example For Students

Renaissance in the tempest Essay Renaissance means rebirth, which marks a shift from seeing humans as sinners to a focus on their potentials and achievements. Humanism was key part of Renaissance spirit. Quest for knowledge and power, a spirit of adventure, a quest for exploring new territories, presence of evil in the politics and interest in magic are the Renaissance element in The Tempest. The plays major focus is on Prospered quest for perfection, knowledge and power. He devotes himself to learning even to the extent of neglecting his duties as a ruler. Use of magic is a weapon through which he can attain perfection. He attains to the status of God on the island assigning roles to the people, commanding and punishing them whenever they go wrong. The act of Notations usurpation of power gives us insights into the evil that was apart of Renaissance politics. The predominance of magic in the play shows the Renaissance kings interest is in the magical things. Prosper leaves Milan and happens to land on new island. This incident of traveling through sea, facing shipwreck, coming to a new land reminds us of the spirit of adventure of Renaissance times made possible by the invention of compass. The quest for geographical discovery of the time is vividly referred to. The long process of colonization began during the Renaissance period. Prosper goes to Scallions island and gives it culture and rules over it. He seems to have fulfilled the colonizing mission. He is the representative of western civilization, goes to a wild locale and molds it in the image of his own culture. He takes the land away from Scoria to whom it legally belongs. Notations greed for power, Prospered quest for knowledge and perfection as well as his spirit of adventure form the Renaissance elements of the play. The use of magic as a means for gaining perfection and the colonization of the island also makes The Tempest a typical Renaissance drama.

Rock Joints free essay sample

A joint is defined as a fracture in a rock between the sides of which there is no observable relative movement. They are present is most consolidated rocks of igneous, metamorphic and sedimentary origin. Joints may form as a result of either diastrophism or contraction. Description: (i) A series of parallel joints is called a joint set. (ii) Two or more joint sets intersecting each other produce a joint system. (iii) Two sets of joints nearly at right angles to one another, produced by the same stress system, is known as conjugate system. iv) A persistent joint or set which may be horizontal or vertical is called master joint. Classification: 1. According to the mode of origin, three types of joints have been recognised, as follows: (a) Tensional joints: These are also known as shrinkage joints. In igneous rocks, they are produced as a consequence of contraction due to cooling. Columnar Structure which characterises many basic extrusive and intrusive, consists of long hexagonal blocks closely packed together. We will write a custom essay sample on Rock Joints or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In granites and granodiorites several sets of joints may be observed, but commonly three sets are prominent-one horizontal and two vertical at right angles to each other and to the Horizontal set. If these sets are more or less equally spaced, the fracture planes give rise to cubical blocks; the jointing is then termed Mural jointing. Joints formed in little deformed sedimentary rocks are due to tension caused by compaction and shrinkage as sediments are considerable into sedimentary rocks. Tensional joints may also be due to deformation. b) Sheet joints: These joints develop in sets and are more or less parallel to the surface of the ground, especially in plutonic igneous intrusions such as granite. They may originate due to unloading of the rock mass when the cover is removed through the processes of erosion. (c) Tectonic joints: These are also known as shear joints. They are formed in a rock under compression. They originate as a direct result of folding or thrusting in rocks. Gen erally they are of three types: (i) Strike set: Longitudinal joints parallel to the fold axis. (ii) Dip-set: Also known as cross-joints, perpendicular to the longitudinal joints. (iii) Diagonal set: Which is a conjugate set of oblique joints, -which lie at rather less than 45Â ° to the direction of tectonic-axis. 2. According to the geometric classification of joints, there are three important varieties, like strike-joints, dip joints and diagonal joints, which are totally with respect to the regional strike and dip of the country rocks. Joints may be open or closed. The closed joints are also known as latent, blind or incipient joints. They may become open as a result of weathering, which is commonly found in jointed lime- Stones. Recognition of joints in the field and their effects on out crops: Joints are generally recognised in the field as faults without displacement. Their dimension varies within wide-limits. Sometimes they are very short in their extension, but in certain cases they are found to extend for miles together. Joints commonly control the drainage pattern of an area. They also determine the shape of coastlines, because they provide a passage, whereby water may penetrate deeply into the rockmass, thus allowing weathering to take place. Jointed rocks are pervious to fluids and hence may act as aquifers or reservoir rocks for oil or natural gas. The presence or absence of joints in a region matters much to quarrymen and miners because it determines the ease with which query and mining can be accomplished. Sometimes joints act as avenues for molten rock materials to come above the surface. It also determines the localisation of some mineral deposits.
