Assessment And Classroom Based Assessment English Language Essay

Assessment And Classroom Based Assessment English Language Essay The aim of this chapter is to look at relevant research studies in relation to assessment in the classroom context, and to explore the role of classroom assessment in more details, with a specific focus on formative language assessment. It appears that the teachers classroom assessment practices and strategies may directly impact learners learning, and this includes young learners.(Oksana:not only with young learnersà ¢Ã¢â€š ¬Ã‚ ¦..so what should I put here) Classroom teachers are in the front line of helping learners learning and assessing their performance in the classroom. Thus, the literature review is mainly concerned with the role of classroom assessment and the relationship between classroom assessment practices and learning. The following section clarifies some terminology and explores the links between assessment and learning with young language learners in the EFL context through a review of literature on experiences of assessment with primary-age learners. 2.2 Definitions of assessment and classroom-based assessment In this section, the definition of the term assessment is provided and the definition of classroom-based assessment (CBA) is discussed to provide more details of the relationship between assessment and learning in classrooms. In the educational context, the term assessment is often associated with testing for most of the teachers, learners and other stakeholders. However, testing is only one element of assessment and it actually encompasses a wider range of factors from tests to dynamic and collaborative activities and tasks. Therefore, it is necessary to clarify the difference between assessment and testing before looking at the definition of classroom-based assessment(Oksana: insert page numberà ¢Ã¢â€š ¬Ã‚ ¦what?). 2.2.1 The distinction between assessment and testing Ioannou-Georgior and Sophie (2003: 4) provide a broader interpretation of assessment; they describe assessment as a general term which includes all methods used to gather information about childrens knowledge, ability, understanding, attitudes and motivation. Assessment can be carried out through a number of instruments (for example, test, self-assessment), and can be formal or informal. This definition suggests that teachers may use both formal and informal methods to collect information in relation to learners performance, such as their ability and attitudes, as an evidence of learning. Ioannou-Georgior and Sophie (ibid) point out that assessment refers to all kinds of methods, whether they are formal or informal, with the aim of collecting evidences of learners learning.(Oksana: similar to above, suggestion: remove it) The studies of Rea-Dickins(2000), Lambert and Lines (2000) go further to suggest that assessment is a constant ongoing process rather than a onetime thing. Rea-Dickins (2000) illustrates assessment as the general process of monitoring of keeping track of the learners progress. (p. 376). She highlights that such process is a continuous method to monitor the learners performance. Lambert and Lines (2000) also show the similar view of point, they define assessment as the process of gathering, interpreting, recording and using information about pupils responses to educational tasks (p. 4) From their viewpoint, assessment is related to what teachers do during the process of teaching and learning, including gathering, diagnosing, recording and using information about pupils performance and feedback. As can be seen, assessment is a part of both teachers and learners life within classroom and is integrated to the process of teaching and learning. It is also used to monitor and respond to lea rners regular work, such as learning activities, tasks and tests. On the other hand, testing refers to a procedure that is used to measure learners ability by teachers and examiners (Rea-Dickins, 2000). According to Ioannou-Georgior and Sophie (2003), testing is a procedure with a certain objective and is used by teachers to assess learners performance in order to understand whether the learner has achieved this objective or not. They also point out that testing used tasks or exercises and assigns marks or grades based on quantitative results (p. 4) This seems to suggest that testing is one of the tools that used by teachers to assess their learners ability and is a way to demonstrate what learners have learnt. It also implies that testing is a onetime thing rather than an ongoing process. As can be seen, testing is a procedure with a certain objective and is used to collect quantitative results, in terms of marks or grades. It is used to measure what the learners have learnt and to check whether they have met their goal or not; meanwhile, assessme nt refers to all methods of collecting both quantitative and qualitative data in relation to learners performance and is a continuous process. (Oksana: Yes, but it is classroom based assessment specifically that does thisà ¢Ã¢â€š ¬Ã‚ ¦..what?)In fact, through clarifying the boundaries between testing and assessment may help us to get insight into the meaning and definition of classroom-based assessment. 2.2.2 Definition of Classroom-Based Assessment Classroom-based assessment is defined by Airasian as the process of collecting, synthesizing and interpreting information to aid in classroom decision making (2005, p. 2). He highlights the work that teachers need to take during the process of assessment in the classroom context, with the aim of supporting teachers in decision making, such as deciding what forms of assessment are most appropriate for gaining information about learners learning and measuring achievement. In classrooms, teachers collect data in relation to learners needs, strength, and weakness and try to interpret the information on the basis of teachers own beliefs, capacities and knowledge. They then provide help to learners and may be able to support individual learning needs. Such ongoing processes, including assigning grades, providing feedback and learning opportunities, and modifying the teaching and learning, are aiming to renew, keep track and record learners performance in the classroom. By doing so, teacher s may be able to enhance learners learning and help them to close the gap between their current status and their target level (Sadler 1989). Further, Mckay describes that classroom assessment or teacher assessment refers to assessment carried out by teachers in the classroom (2006, p. 140). He then notes that classroom assessment may be formative, for instance, when the purpose is to provide feedback to help learners improve learning, or it may be summative, when the purpose is to record and report pupils achievement and attainment (Rea-Dickins 2000). As can be seen, the purposes for classroom assessment may lead to using assessment information formatively or summatively by teachers. For example, they may need to use formative assessment to identify learner needs and use summative assessment to provide learners achievement to school authorities in the end of a school year. In fact, there are a variety of purposes for teachers to use classroom assessment. Rea-Dickins suggests three objectives of using classroom assessment: teaching, nurturing learning, and measuring learning (2000). In other words, teachers may use classro om assessment to modify their teaching methods and materials, provide appropriate help to learners and meet the bureaucratic demands. Classroom assessment plays a significant role in collecting information about learners learning and can also be used to support teachers teaching and learning (Rea-Dickins, 2001). It is a continuous and integrated process which can be planned in advance as well as be unplanned, such as observing learners language performance during the course of teaching and assessment activities. The roles of teachers may have an impact on learners learning in the classroom, whether as facilitators to develop learners language development or as assessors to measure learners language learning, (Rea-Dickins, 2008). Teachers may use both formative and summative assessment as pedagogic tools to scaffold learners, adjust their teaching, and assign grades for learners in the classroom. It is important for teachers to develop classroom assessment skills and strategies, and bring about positive change in classrooms. The aims of adopting classroom assessment strategies are to support learners learning and te achers teaching, and to meet the ultimate achievement of the curriculum goals. Rea-Dickins (2001) provides a model of classroom assessment which illustrates teachers roles in four stages in the classroom assessment process (see Figure 2.1). It also reveals the fact that teachers may need to play a mediating role in order to deal with various demands from improving learning and modifying teaching. For instance, in stage 1, the Planning stage, teachers may be interpreters to explain the learning goals and assessment criteria with learners and evaluators to identify learners needs and levels. They may become supporter in stage 2 in order to scaffold learners and provide feedback to them. As for stage 3, teachers may also need to be interpreters to interpret the learning evidence and improvers to refine the assessment process; meanwhile, they may need to be reports to report and record the learning progress to administrative authorities. Stage 1: Planning Identifying the purpose for the assessment?(why?) Choosing the assessment activity(how) Preparing the learners for the assessment Who chooses/decides for each of the above Stage 4: Recording Dissemination Recording reporting progress toward NC Formal review for LEA or internal school purposes Strategies for dissemination of formal review of learners Stage 2: Implementation Introducing the assessment(why, what, how) Scaffolding, during assessment activity Learner self- peer monitoring Feedback to learners(immediate) Stage 3: Monitoring Recording evidence of achievement Interpreting evidence obtained from an assessment Revising teaching and learning plans Sharing findings with other teachers Feedback to learners (delayed) Figure 2.1 Process and strategies in classroom assessment  [1]   However, teachers may not be able to predict the complex interaction between these two assessment purposes before actually implementing the assessment active. For instance, teacher-planned summative assessment may also provide formative assessment opportunities for students during the teaching process. Rea-Dickins (2006) points out that the boundary and interaction between formative and summative purposes of assessment cannot be identified in any watertight way in advance, as they will unfold and be enacted through the classroom discourse (p. 183). As can be seen, teachers need to be flexible with their classroom assessment practices and be able to use both formative and summative assessment as pedagogic tools to scaffold learners, adjust their teaching, and assign grades for learners in the classroom. Thus, it is important for teachers to understand the functions of both formative and summative assessments and how to use them to modify their teaching, enhance pupil achievement, and report to school authorities, parents and other stakeholders. 2.3 The Functions of Classroom Assessment: Formative and Summative Assessment On the basis of the definition of classroom assessment (2.2), classroom assessment may be used as a variety of instruments by teachers to collect data in relation to learners needs, ability, knowledge, understanding and performance in the classroom. This seems to imply the primary role teachers play in classroom assessment process and the importance of linking formative and summative assessment to effectively enhance learners learning and report it to other stakeholders, including parents, other teachers, learners themselves, and school authorities. In this section, the functions of classroom assessment, in terms of formative and summative assessment, will be discussed, particularly with assessment for learning, through a review of the literature in relation to the role of both formative and summative assessment in classrooms. 2.3.1 The Role of Formative and Summative Assessment Classroom teachers are in the front line of assisting learners to develop their ability and enhance their learning, thus, it is crucial for teachers to recognize the different functions and characteristics between formative and summative assessments and to integrate them into everyday teaching and learning. Harlen and James (1997) share the different roles of formative and summative assessment in classroom assessment. They urge the need to distinguish the differences between formative and summative assessment, in terms of the functions and characteristics, and then connect and wave them together. To reveal the complexities of the differences between formative and summative, some research reports have provided a variety of interpretations to help teachers to clarify the concept of formative and summative assessment. According to the report of Task Group on Assessment and Testing, known as TGAT, it defines formative and summative assessment through clarifying the different purposes and timing between them. For formative assessment, teachers may use it to understand the the positive achievements of a pupil (DES/WO, 1988, para. 23) (Oksana: This is quite an old reference, is there anything newer/more recent on this point?)and then plan their teaching in order to help the pupil to reach to the next step. It highlights the dynamic process of teaching and learning in the classroom and more importantly, it points out the future direction through using the results of assessment. Formative assessment is a continuous process of adjusting teachers teaching and learners learning; meanwhile, summative assessment is used for systematic recording of learners overall achievement. In other words, teachers may use summative assessment to note learners performance, such as recording the grade or scores of teacher made and standardized tests, after a certain period of time. In 2001, Clarke expressed similar views in providing a clear illustration for formative and summative assessment: If we think of our children as plantsà ¢Ã¢â€š ¬Ã‚ ¦summative assessment of the plants is the process of simply measuring them. The measurements might be interesting to compare and analyse, but, in themselves, they do not affect the growth of the plants. Formative assessment, on the other hand, is the garden equivalent of feeding and watering the plants directly affecting their growth (p2). As can be seen, the main function of formative assessment is to nurture pupils and improve learning, which is a continuous process of interaction between teachers and learners. For instance, in classrooms, teachers provide guidance for learners toward improvement through formative assessment feedback during the processes of teaching and learning. As for summative assessment, it takes place after the teaching and learning. Teachers may grade or make judgments in relation to learners learning in order to inform and report to other stakeholders. In the classroom, teachers use formative assessment to help learners learning as well as modify their own teaching methods and materials. They also use summative assessment to assign grades and report attainment at the end of a school year for administrative purposes (Bachman Palmer 1996). As such, formative assessment requires the ability of the teacher to diagnose learners performance, in terms of what causes him or her to get struck, and to help learner to understand what to learn, how they learn, and how well they have learned. 2.3.2 Formative Classroom Assessment: assessment for learning More recently, the focus of the classroom assessment studies has shifted from forms of test to the interactions between assessment and classroom learning. This shift also highlights the importance of the improvement of learning through formative teacher assessment. Black and Wiliam (1998) review a variety of past research studies in relation to classroom formative assessment. They point out that several empirical studies show evidence to support the claim that improving formative assessment do raise standards and help pupils learning, particularly with low ability pupils. They also present evidence in relation to how teachers use formative assessment practices and strategies to enhance pupils learning in the field of general education. A broader explanation of formative assessment is provided by Black and Wiliam, they illustrate that all those activities undertaken by teachers, and/or by their students, which provide information to be used as feedback to modify the teaching and learning activities in which they are engaged (1998, p.7). Their interpretation not only points out that formative assessment activities can be used by both teachers and learners but also indicates how teachers and students use feedback to adjust the teaching and learning. From this perspective, formative assessment is embedded in teaching and learning and can be used to prompt learner learning. Key formative assessment strategies, such as effective teacher feedback, teacher scaffolding, self- and peer- assessment, and raising learners self-esteem and motivation, may be integrated and embedded within teacher-learner(s) interactions(Rea-Dickins 2006). As can be seen, the activities that conduct by teachers, such as observation, teacher made tests, take-home tasks, and learners, including self- and peer- assessment, would provide information to help both teachers and learners improve themselves. Further, Brindley (2001) points out formative assessment should undertake by teachers during the learning process, by doing so, teachers can use the results to improve instruction (p. 137). In addition, Sadler (1989) connects formative assessment with feedback and believes that feedback to teachers and to learners are separate. He suggests that the aim of using feedback for teachers is to diagnose learners performance and modify their teaching in order to help learners to enhance their abilities; meanwhile, for learners, the purpose of using feedback is to monitor their performance and understand their own learning weaknesses and strengths. Further, Tunstall and Gipps (1996, p.393) identify two types of feedback used by teachers in classrooms: evaluative and descriptive feedback respectively. They suggest that the former seems to be more close to affective and conative (effort-based) aspects of learning with a performance goal, whereas the latter places the emphasis on the cognitive development with a mastery goal. Teachers act as facilitators in providing descriptive types of feedback, such as making suggestions and questioning as part of discussion, rather than directing (p. 401). As can be seen, there is a greater links between descriptive feedback and formative assessment. However, Torrance and Pryor (1998) point out that teacher feedback may have a negative influence on learners, for instance, when the teacher tries to correct learners mistakes which may lead to the impression of learners producing wrong answers. It may even be seen as criticism by the pupils and discourage learners self-esteem. Further, teacher feedback with praise may result in encouraging competition among learners instead of increasing learners motivation. Thus, it is important for teachers to recognize the influences and impact of formative assessment feedback on learner motivation and self-esteem. To sum up, classroom assessment is used by teachers to collect data in relation to the process and attainment of learners with aim of responding to individual needs and curricular demands. Formative assessment is crucial in enhancing learner learning and closing the gap between learners actual level and potential level. The following section explored assessment of young language learners in a foreign classroom context through review of past research studies in relation to classroom assessment in practice. 2.4Research on Assessment of Young Learners in the EFL Classrooms In this section, the relevant research studies of classroom assessment of young language learners are explored, followed by introducing a unique Taiwanese educational context, in terms of learning English in private ESL schools, as the classroom assessment context in this research. 2.4.1 Classroom Assessment of Young Language Learners Rea-Dickins (2000) points out that since the 1990s research studies in relation to assessment for foreign language learners has been more in evidence (e.g., Low et al., 1993; McKay et al., 1994; Edelenbos and Johnstone,1996; Breen et al., 1997; Leung and Teasdale, 1997). Language Testing proposes a special issue that is focusing on assessment for young language learners, who ages 5 to about 12, in the school system. The key idea of these reports in this issue is related to a variety of purposes for assessment for young language learners within an early years language learning curriculum which results in raising the awareness of wider issues in relation to assessment of young language learners, such as how the validity of classroom-based assessment is achieved. Teadeale and Leung (2000) draw the attention to the validity of implement alternative assessment and monitoring learners learning performance through teacher assessment. Rea-Dickins and Gardner (2000) also look at the same issue in relation to the implementation of formative classroom assessment, in terms of keeping track of learners language development, in the English as a Second Language (ESL) context. Their findings suggest the potential variables which may influence the validity of teacher assessment during the assessment procedure. This is followed by Gattullo who explores the way to implement formative assessment in the Italian primary foreign language classroom, where English is taught since grade 3 (age 8). She investigates different formative assessment processes through analyzing classroom assessment discourses and she also observes the everyday interactions between teachers and learners. The results suggest that instead of using formative assessment actions which may be m ore beneficial for learning, including observing process, examining product and metacognitive questioning; teachers use more common actions, such as questioning, correcting and judging. Continuing the theme of formative assessment of primary learners in the EFL context, Zangl (2000) provides the methods of assessment to gain information in relation to primary-age learners language skills. She argues that teachers may be able to draw a developmental picture for individual learners, including their general interactional skills and specific language skills, through ongoing assessment throughout primary school. Hasselgren (2000) looks at the innovative ways to develop materials, such as tests, teacher assessment, and learners self-assessment, which can improve both teachers and learners assessment skills in Norwegian primary schools. In the context of Norway, one significant difference is that there is no tradition of testing for young language learners due to local policy. This contributes to high-demand assessment methods, particularly in materials development and task design, and to the implementation of formative assessment, in terms of assessment for learning. Both teachers and learners are encouraged to develop their ability to assess. As can be seen, the national policy is one of important variables that influences teachers attitude towards integrating classroom-based assessment into their everyday language teaching. It is also crucial to take variables, such as learners prior cultural knowledge, teachers knowledge and ability in assessment, and the English curriculum, into account when assessing primary-age learners of English as a foreign language. Teachers should choose and design the appropriate assessment material for Young language learners. The material should be well adapted to learners cognitive and linguistic skills and to their interests. The work of Hasselgren suggests that classroom assessment may be influenced by a variety of factors, particularly by the national policy. These external elements, such as the government policy and English curriculum, may have direct impact on the implementation of assessment, teachers attitude towards classroom assessment and their classroom assessment practices in the EFL context. A brief history of primary school English education in Taiwan is explored in the next section to gain insight into a special English classroom in Taiwan. 2.4.2 ESL Program in Taiwan English teaching and learning for young learners has become increasingly important in Asian countries, such as Taiwan, China, Japan and Korea, where learners study English as a Foreign Language (EFL) over the past few decades. At this point it is useful to clarify some terminology before introducing the English educational context in Taiwan. The term English as a Second Language (ESL) used in countries, , such as Canada, North America and Australia, which refers to learners who are using English as the medium of instruction in school contexts but who are not English first language (L1) speakers (Rea-Dickins, 2000, p. 115). On the other hand, the term English as Foreign Language (EFL) refers to when English is taught to non-native English speakers in non- English speaking areas, such as Europe, Asia, and Africa. In 1997, the Ministry of Education (MOE) in Taiwan decided to implement curricular and instructional reforms in elementary and junior high school education. One of the most significant changes is that English courses are officially introduced in grade 3 (age 9) with two 40-minute lessons per week (Ministry of Education, Republic of China, 2010). Since then, learning English has become a popular movement for young learners from the ages of 5 to 12 across the country. Butler (2004) points out that some Asian countries, such as Korea, Taiwan, and Japan, have introduced English language instruction at the elementary school level, with special focus on oral communication skills. Although the officially suggested starting age is 9, most parents want their children to learn English as soon as possible. The assumption of the younger the better in foreign language acquisition is supported by many Taiwanese parents, who believe an early start will help their children to achieve greater profici ency. These factors above contribute to the significant growth in the number of cram schools and private language schools across the country over the last decade. Cram school also known as abuxiban in Taiwan are very common and popular in competitive Asian countries, particularly in Taiwan and Japan. The aim of these schools is to help pupils to enhance their achievement scores (Harnisch, 1994; Oneil Fukumura, 1992; Stevenson Stigler, 1992). In 1999, a report from China Central News, on 6 April 1999, stated that at least more than one quarter of elementary pupils attend private language institutions after school to learn English. Tsai and Kuo (2008) report that there are more than 5,000 cram schools in Taiwan. Most English cram schools offer additional after-school teaching to enhance pupils English ability. In particular, numerous so-called ESL schools aim to help Taiwanese learners to learn English as a Second Language (ESL) through using American elementary textbooks and teaching all subjects, including handwriting, computer, music, social science, reading, math, science, grammar, phonics and writing, in English. They also offer an ESL p rogram to kindergarten children of 3 years old up to students in grade 6 (age 12). In general, kindergarten pupils and grade 1 to 2 learners receive an average of 4 to 5 lessons a day, each 30 minutes long. As for grade 3 to 6 learners, they receive approximately 2 to 3 lessons a day due to their longer elementary school hours. Such ESL schools provide a unique educational context to investigate these ESL English teachers perceptions of classroom assessment and their own classroom assessment practices.

Landscape in the Classic Western

The article â€Å"Landscape in the Western Classic text: Landscape in the Classic Hollywood Western† by Stanley Solomon focuses around the central claim that landscape is definitive to the film genre of Western, defining both plot and characterization. First, the severity of the barren landscape against which the plot of Western movies revolves suggests that the characters in the movie either have to be rugged or likely to fall prey to more rugged ones. Scarcely populated rural places allow for the clear-cut distinction between an honest group of citizens with local sheriff as their leader and a gang of immoral criminals. Since the landscape is clear-cut and straightforward, so are the characters and their moral traits. The same is true for sharply delineated codes of behavior that have to be grasped by both criminals and good guys. The severe natural and human environments, in which the characters of the Western have to act, develop skills crucial to survival, including â€Å"competence in the face of danger, courage, determination, and endurance† (Solomon 1976). The threat in most cases comes not from nature that, for all its mercilessness, is fair and predictable in its threats, but from human villains. The struggle between moral and immoral characters is the cornerstone of the plot. A peculiar environment often tells a lot about the women’s role. Most of female characters, exactly like men, should possess strength of character and survival skills that are looked up to by men. At the same time, women bring a humanizing effect to movies, supporting the value of human life. Western movies often call for insights into the past of the character, in contrast to urban movies where the emphasis is on the throbbing present of the city life. A Western character arrives at the scene a mature man, shaped by his past experiences, that often involve some indelible tragedy. Understanding a character’s past is essential, although information of it is often presented as a mere hint. â€Å"The interrelationships of landscape, characterization, and the past† form the central focus of the Western genre (Solomon 1976).

How Global Warming Effect the Environment

Charlotte Chiero Wk: 8 Assignment: Project 1-Research Project Global Warming Westwood College Global Warming is an increase in the Earth’s temperature that is caused by gases, chemicals, and heat trapped or introduced into the Earth’s atmosphere causing temperatures to increase. Everyone here on earth is responsible for Global Warming; it is something that we all are responsible for, instead of pointing the finger at each other we need to start working on a solution to slow down the warming effect in our country or world. If we do not become more educated on how we our destroying the world there will be nothing left.Global Warming has become so bad that we cannot tell the difference between seasons and this is because of the damage that we have done to our earth resources. To understand the Global Warming effect we need to comprehend what man has done to this world first we have destroyed our trees and not planting new ones exposing the earth to all kinds of unsafe elem ents. This is called deforestation. So why are we doing this. According to the National Geographic this is for agriculture farmers cut forests to provide more room for planting crops or grazing livestock.Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in a process known as â€Å"slash and burn† agriculture. Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Forests are also cut as a result of growing urban sprawl. Deforestation has many negative effects on the environment. The most dramatic impact is a loss of habitat for millions of species. Seventy percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes.In addition deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night. This disruption leads to more extreme temperatures swings that can be harmful to plants and animals.Further more trees also play a critical role in absorbing the greenhouse gases that fuel global warming. Fewer forests mean larger amounts of greenhouse gases entering the atmosphere and increased speed and severity of global warming. The quickest solution to deforestation would be to simply stop cutting down trees. A more workable solution is to carefully manage forest resources by eliminating clear-cutting to make sure that forest environments remain intact. The cutting that does occur should be balanced by the planting of enough young trees to replace the older ones felled i n any given forest.What we have to remember is that not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. We have also, introduced chemicals in the atmosphere that is destroying our ozone layers. Trying to find solutions to problems like this will take all of us to work together all over the world to slow down the hothouse effects. As I mentioned early this is why we need our trees to help filter out all these harmful chemicals that our world is exposed to.Some of these chemicals are electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. According to Planet Save 40% of U. S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry. Every day, more electric gadgets flood the market, and without widespread alternative energy sourc es, we are highly dependent on burning coal for our personal and commercial electrical supply.Another is in the last half of the 20th Century; the use of chemical fertilizers (as opposed to the historical use of animal manure) has risen dramatically. The high rate of application of nitrogen-rich fertilizers has effects on the heat storage of cropland (nitrogen oxides have 300 times more heat-trapping capacity per unit of volume than carbon dioxide) and the run-off of excess fertilizers creates ‘dead-zones’ in our oceans. In addition to these effects, high nitrate levels in groundwater due to over-fertilization are cause for concern for human health. References: Planet Save. (n. d. ).

Labor Unions in the Late 19th Century America - 1511 Words

During a time period of great advancement in technology, the late 19th century could appropriately dub itself as an industrial revolution. Rapid transformations of the work-place worsened working conditions and prompted the common laborer to join forces with others in order to create labor unions. Although these unions were fueled with excellent intentions and driven by exasperated motivation, these organizations did little to improve the working conditions during this particular time frame. It wasn’t until the 20th century that tangible changes in the workplace, stability in personal finance, and the public’s perception of their motivations that organized labor truly improved the position of workers from 1875 to 1900. Although†¦show more content†¦An observer of strikes established in order to promote such strong points as these higher wages were even viewed as irrational and hopeless. (Document B). If these public presences yielded no reward, then the uni ons obviously did not accomplish what they set out to do in the first place. In this way, the organized labor movements promoting higher wages did not result in the improvement of the position of workers. They were still trapped in those disgusting tenements for years to follow. Because of a lack of clear organization of these labor unions, a rather unfavorable notion stained the public perception of various groups. As depicted in Frank Leslie s Illustrated Newspaper, the label of â€Å"anarchist† was associated with labor unions, and specifically, the Knights of Labor. ( Document F) Quite obviously, this group was viewed as a bunch of rabble-rousers and very violent. This most certainly did not help the popularity and success of labor unions because this negative connotation lead to the downfall of this once very popular labor group. For example, in Chicago, a demonstration by the Knights of Labor turned into the Haymarket Square Riot and lead to the death of a group of poli ce officers. The term â€Å"riot† practically labels the group as destructive and uncivil and therefore made them looked down upon by the public. A non-existent group certainly can not make the changes they set out to do in the first place!
