Compare And Contrast Education Reform - 1474 Words

An educational system is a means to develop a workforce, to improve the socioeconomic status of the poor via social mobility, and to create a shared culture. Given these important roles, educational systems are targets for social reformers. Joseph Lancaster and Arne Duncan were both education reformers with strong and influential ideas about what and how students are taught. Lancaster was a London schoolmaster and eventual leader of the Monitorial education reform movement in the early 1800s. Duncan was the US Secretary of Education from 2009-2015, and led an era of active federal education reform. In comparing and contrasting these two educational reformers from the past and present, there are more similarities than differences.†¦show more content†¦Recent United States Secretary of Education Arne Duncan was still trying to accomplish the same goal. In Lancaster s book Improvements in Education he argues people should invest money into the education of the poor. â€Å"W hy then so eager in the pursuit of riches? and why not rather pay that attention to the infant poor, which their wants requires?† (Improvements in Education). This line demonstrates that Lancaster believes people should put money towards the education of the poor so that they can have a chance to better their place in society. Lancaster tried to lower the cost of education by developing the monitorial system of education which uses less teachers and so lowers salary costs. This is similar to Arne Duncan s emphasis on investing more money into education and in managing costs. At the end of his term, The Washington Post reported â€Å"his agency directed $100 billion in stimulus funds to districts small and large that were otherwise facing severe job cuts in the wake of the 2008 recession. The move preserved an estimated 350,000 teaching jobs.† In his speeches, Duncan said that â€Å"states and institutions of higher education will need to meet us halfway in doing more to keep college costs down and boost completion†. This statement made by Duncan shows that both he and Lancaster have similar ideas on the cost of education, they both believe that education was a social investment and that the cost of education should be lowered so poorer people canShow MoreRelatedAll The King s Men By Robert Penn Warren889 Words   |  4 Pagespersonal story of Jack as the latter comes to realize his responsibility for the world around him.

This work of literature was based on Augustus and his role in founding the empire. In this also included, â€Å"Roman virtues- patriotism, devotion to the family, duty to the state, and a strong sense of religion.† Other classical writers of the time were Horace, whose poetry was based on the value of moderation and the beauty of friendships. The two major leaders in the art of science were Ptolemy and Galen. Ptolemy was a scientist of math, geography, and astronomy. He wrote, Mathematical Composition which was the prominent all the way through The Middle Ages. As Ptolemy was to math and astronomy, Galen was the prominent medicinal scientist of his time. He was known for dissecting humans and also animals. Even though much of his work was found to be wrong, his contribution to the future of anatomy was great. Roman government was now being governed differently and with this came new law. Roman law started off by passing through two stages, the formation of civil law and the formation of the law of nations. The law of nations came to be applied throughout the empire, although i t never fully applied local law. These laws were brought about to bring everyone together.

Relative Humidity Essay Sample free essay sample

This activity will look at two of the most cardinal and of import elements of conditions: temperature and humidness. Aims: 1. The pupils will detect the demand for mensurating instruments to quantify conditions observations. 2. The pupils will larn how to utilize a sling psychrometer to find temperature and comparative humidness values. 3. The pupils will explicate and understand the difference between absolute and comparative humidness and the relationships between temperature and atmospheric humidness. Introduction: Atmospheric Temperature is one of the most often considered of the many meteoric elements. This influence of air temperature on the growing and wellbeing of earth’s life signifiers is paramount. Temperature is fundamentally a step of the molecular kinetic energy of a substance. ( Or how fast the molecules are traveling ) . Therefore mention points upon which compare molecular activities or temperatures are needed. The freezing point and boiling points of H2O are used as 32OF or 0OCis the freeze point and 212OF or 100OC is the boiling point. Water is a basic necessity for the life signifiers here on Earth. At a given minute. merely about 1/100. 000 portion of the earth’s supply of H2O is found in the ambiance. yet it is this atmospheric H2O that brings wet to the surface of the Earth and makes it habitable. In the hydrologic rhythm. H2O is invariably being moved from the earth’s surface into the troposphere where it gives rise to overcast and precipitation. thereby conveying the H2O back to the surface once more. Humidity is defined as the sum of H2O vapour in the ambiance. It is measured in several ways. In one method. the mass of the H2O vapour is measured per unit volume. normally a three-dimensional metre ( M3 ) . This step of humidness is referred to as absolute humidness and reported as gms H2O/m3. The humidness may besides be expressed as a commixture ratio. The blending ratio represents the mass of H2O vapour in the ambiance measured in gms per kg mass ( g/kg ) of dry air. Specific humidness. yet another manner to mensurate and describe humidness. is basically the same as the commixture ratio. differing merely in that the sample mass of air includes the mass of H2O vapour contained within it. While each of the methods merely described to describe humidness involve mensurating the mass of H2O vapour within a sample unit of air. there is yet another manner to mensurate the sum of H2O vapour in the ambiance that utilizes a different attack. The construct of partial vapour force per unit area breaks out the sum of the entire atmospheric force per unit area attributable entirely to H2O vapour. For case if the atmospheric force per unit area is 1000 millibars. and H2O vapor represents 3 % of the mass of the air ( which is manifested as air force per unit area ) we could depict the sum of H2O vapor present by describing the existent vapour force per unit area as 30 millibars. Relative humidness. the most widely reported step of humidness. is non a direct step of the sum of H2O vapour in the ambiance. but instead the ratio of the air’s H2O vapour content to its H2O vapour capacity at a given temperature. The capacity is the sum of H2O vapour needed to bring forth impregnation at that peculiar temperature. The assorted expression for comparative humidness are: sum of H2O vapour in ambiance ( per unit ) X 100 H2O vapour capacity of ambiance ( per unit ) or blending ratioX 100impregnation blending ratio or existent vapour force per unit area X 100impregnation vapour force per unit area Humidity can be expressed in several ways. One step of humidness is vapor force per unit area. Every gas bing in air is lending to portion of the force per unit area being exerted by the air. The vapor force per unit area is the portion of the entire atmospheric force per unit area being exerted by the H2O vapour in the air. Therefore. it is a step of the existent vapour content or absolute humidness. If the air is keeping the maximal sum of vapour capable of keeping. it is said to be saturated and the vapour content can be expressed as the concentrated vapour force per unit area. There is a important relationship between the temperature of the air and its capacity to keep wet. The higher the temperature the greater of the air to keep wet. This relationship between temperature and saturated vapor force per unit area. Simple Calculations:Using the expression stated above in this lab execute the undermentioned computations and reply the inquiries. You must demo your work. 1 If the H2O vapour capacity of the ambiance in a given location is 25 gms per kg of air sampled. and the existent sum of H2O vapour nowadays is 5 gms per kg of air sampled. what is the comparative humidness? Water vapor/ West Virginia capacity=rh5g per k/ 25g per k= . 20?100=20RH=20 % 2 If the H2O vapour capacity of the ambiance in a given location is 12gms per kg of air sampled. and the existent sum of H2O vapour nowadays is 3 gms per kg of air sampled. what is the comparative humidness? 3g per k/12g per k= . 25?100=25RH=25 % 3 If the blending ratio of a sample of air is 5 grams/kilogram. and the temperature of the sample is 15 grades Celsius. giving a impregnation blending ratio of 10 grams/kilogram. what is the comparative humidness of the sample? 5gk/10gk= . 5?100= 50RH=50 % 4 If the blending ratio of a sample of air is 2 grams/kilogram. and the temperature of the sample is 25 grades Celsius. giving a impregnation blending ratio of 20 grams/kilogram. what is the comparative humidness of the sample? 2g per k/20g per k= . 10?100=10RH=10 % 5 If the vapour force per unit area is 10 millibars and the impregnation vapour force per unit area is 40 millibars. what is the comparative humidness of the ambiance? Actual/saturated10 millibars/40 millibars= . 25?100=25RH=25 % 6 Why was the comparative humidness in inquiry 2 higher than that calculated for inquiry 1. even though the sum of H2O vapour nowadays in the ambiance was less? Possibly because the capacity of the H2O vapour was a factor and thetemperature outside had an impact.Dry air will be denser or heavier than a column of air incorporating any H2O vapour. Use of the Sling Psychrometer The sling psychrometer is a simple. yet effectual instrument used to find comparative humidness. It does non. nevertheless. give a direct reading of comparative humidness. Psychrometric tabular arraies must be used to obtain the comparative humidness from the temperature informations provided by the psychrometer. In this portion of the lab. you will utilize the sling psychrometer and the psychrometric tabular arraies as demonstrated by the teacher. Use the informations you obtain to finish the chart below: Note: Care must be taken with these instruments. as they are really delicate and easy damaged.

Can you give any accounts for the differences? It is different how the RH compares in the hallway than my sleeping room or exterior. It seems like the bigger the spread in the dry-wet reading. the lower the comparative humidness will be. 2 How does air conditioning alter the comparative humidness of a room? Cooler air can non keep as much wet as warmer air. The procedure of chilling causes the wet to distill and run out out of the air conditioner. 3 How does heating a room alter the comparative humidness? The comparative humidness will travel down. if all you do is heat the room. As the temp goes up. so does the ability of the air to keep more H2O vapour. If you heat the room without adding H2O vapour. so the air is â€Å"drier† compared to what it could be. 4 Can you believe of any agents or fortunes that may do the commixture ratio in a room to alter? Possibly person is utilizing an air conditioner or a humidifier/ dehumidifier. 5 Given the fact that the molecular weight of H2O vapour is less than that of dry air. what affect does increasing humidness have on the denseness of the ambiance? Does this run counter to what your intuition tells you? Yes moist air is lighter than dry air. Subconsciously. this seems sort of dumb. because air incorporating H2O should be heavier than dry air. but the difference is so great that clouds ( contain droplets of wet every bit good as H2O vapour ) readily remain in the air. 6 How does comparative humidness affect the comfort of people? Can you explicate the physiological grounds for this? It makes people experience uncomfortable because when the humidness is higher. perspiration is less able to vaporize. doing a individual feel stickier and hotter. 7 The diurnal ( day-to-day ) relationship between temperature and humidness is such that the lowest humidness should happen in the afternoon hours. It is during these times. nevertheless. when it frequently seems to be most humid and uncomfortable. What could be the ground for this sensed incompatibility? During a warm yearss. we will experience humid because of the combination of high temperatures mixed with more H2O vapour in the air. When the temperature is warm. people exposed to this type of heat will sudate. It is the sudating procedure that we cool down. 8 When dew signifiers on out-of-door objects. can it be assumed that the ambiance is saturated? If so. why is at that place frequently no fog attach toing the dew? If the ambiance is the major beginning of wet ( dewfall ) . a certain sum of airing is needed to replace the vapour that is already condensed. I would believe that this can be assumed to be saturated since the wet forms the dew. There is no fog because the H2O vapour already is condensed into dew.
