No cellphones in class - Essay Example All schools have given teachers to own and use cell phones to school. However, students owning such gadgets in school are still a contentious issue faced with mixed reactions. The first advantage of students carrying their cell phones to school is for security and safety measure. The students can react to emergencies faster and efficiently by contacting relevant rescue teams. In addition, mobile phones that are internet enabled are essential to students when seeking information related to academic contents. Cell phones, therefore, are a good technology to incorporate in the learning because they enhance research and education. Cell phones are also advantageous to learners in the classroom because they find an opportunity to interact with friends, families and other acquaintances through platforms that promote information sharing (Brady 45). That can be useful only when students use phones outside the classroom context. In addition, cell phones also have both print and non-print media that are useful in enhancing learning. Particularly those that have videos and cameras are essential when learning requires realia and images. Such gadgets, therefore, enhance learning. Mobile phones are distracters during learning sessions. Most students participate in anti-learning activities with their cell phones during the learning process. Some students misuse their cell phones by watching censored materials and videos from the internet. Others students send instant texts, listen to music and illegal videos that draw attention from learning activities. Cell phones that have calculators installed make students lazy because they tend to use such machines to solve even simpler mathematical problems. Consequently, learners become dependent by using machines to solve most of their problems. Although the gadgets were regarded as a luxury possessed by adults, it is presently in the hands of school-going children.

Global Warming Research Paper Example | Topics and Well Written Essays - 1000 words

Global Warming - Research Paper Example This decision is fundamentally based upon the assumption that if humans are legally bound to control CO2 emissions, global warming can be reduced. However, scientists vary in their views regarding the existence of global warming as a problem. Many do not attribute this problem to humans. Government’s resolution to finalize such a treaty is being criticized in that if its enforcement is delayed up to some 25 years, it would hardly do anything to lower the temperature after 100 years. In this way, the proposed restrictions of the treaty would do more of economic harm than environmental good. A better idea is to postpone any legal action unless human activity is proved to be the fundamental cause of global warming. Meanwhile, better technology should be developed in order to mitigate the issue of global warming so that both environment and economy remain in good health. Biblebelievers.org.au (n.d.) has discussed certain myths that contradict the beliefs of many. They are discusse d as follows: Myth 1 – scientists mutually consent upon warming up of Earth. According to the ground-level temperature measurements, since 1850, temperature of Earth has only increased from 0.3C to 0.6C. There is no evidence of global warming in the global satellite data of the past 18 years. Thus, saying that the globe is warming up is a myth. Myth 2 – Humans are making the globe warm. ... Scientists’ view on global warming (biblebelievers.org.au, n.d.). Myth 3 – If necessary action is not taken in time, this can be very deleterious for the environment. Immediate government action is required before it gets too late. Proponents of the theory of global warming consented in a 1995 analysis that action to safeguard the environment against global warming can be delayed for at least 25 years without causing any harm to the environment. Governments can cut emissions to approximately 9 billion tons per year now, or wait until 2020 and cut emissions by 12 billion tons per year. Either scenario would result in the desired CO2 concentration of 550 parts per million. Delaying action until 2020 would yield an insignificant temperature rise of 0.2 degrees Celsius by 2100. (biblebelievers.org.au, n.d.). Myth 4 – Global warming caused by humans will create dreadful environmental issues. Such beliefs have been totally rejected by many reputable scientists, particu larly those who researched upon the Intergovernmental Panel on Climate Change (IPCC) of the UN organization. â€Å"There is no actual evidence that carbon dioxide emissions are causing global warming. Note that computer models are just concatenations of calculations you could do on a hand-held calculator, so they are theoretical and cannot be part of any evidence† (David Evans cited in Cook, 2011). International energy statistics are available that tabulate the peat, coal, crude oil and brown coal production for every country starting from 1751. An in-depth analysis of the statistics suggests that the emission of CO2 has increased manifolds in the last century. According to EIA (cited in Cook, 2011), up to 29 billion tonnes of CO2 were released in the year 2006. The level
