Literacy Strategies to Use in Lessons for Struggling Readers

Literacy Strategies to Use in Lessons for Struggling Readers In many districts, students with reading difficulties are identified in the primary grades so that remediation and support can be given as early as possible. But there are struggling students who may need support in reading throughout their academic careers. There may be struggling readers who have entered a district in the later grades when the texts are more complex and the support services less available. Extended remediation for these groups of struggling readers can be less effective if the strategies that are chosen limit a students creativity or choice. Remediation with structured lessons that repeat the same material will result in less content covered by the students. So what strategies can the classroom teacher use to teach these struggling students who cannot read to access the content? When a text is critically important, teachers need to be purposeful in selecting literacy strategies for a content lesson that prepares struggling readers for success. They need to weigh what they know about the students with the most important ideas in the text or content. For example, a teacher may determine that students need to make inferences from a fiction text to understand a character or that students need to understand how a map illustrates how rivers are important to settlement. The teacher needs to consider what all students in the class could use in order to be successful and then balance that decision with the needs of the struggling reader. The first step could be to use an opening activity where all students can be engaged successfully. Successful starters An anticipation guide is a lesson opening strategy meant to activate the students prior knowledge. Struggling students, however, may lack prior knowledge, particularly in the area of vocabulary. The anticipation guide as a starter for struggling readers is also meant to build interest and excitement about a topic and give all students an opportunity for success. Another literacy strategy starter could be a text that all students, regardless of ability, can access. The text must be related to the topic or objective and can be a picture, an audio recording or a video clip. For example, if inferences are the objective of a lesson, students may fill in thought bubbles on photos of people in response to What is this person thinking? Allowing all students access to a common text that has been selected for equal use by all students for the lessons objective is not a remediation activity or a modification.   Prepare vocabulary In designing any lesson, a teacher must select the vocabulary that is necessary for all students to meet the goal for the lessons objective rather than attempt to try to fill in all the gaps in prior knowledge or ability. For example, if the objective of a lesson is to have all students understand that a rivers location is important developing a settlement, then all students will need to become familiar with content specific terms such as port, mouth, and bank. As each of these words has multiple meanings, a teacher can  develop pre-reading activities to familiarize all students before reading. Activities can be developed for vocabulary such as these three different definitions for  bank: The land alongside or sloping down to a river or lakeAn institution for receiving, lendingTo  tip  or  incline  an  airplane Another literacy strategy comes from the research that suggests that older struggling readers can be more successful if high-frequency words are combined in phrases rather than isolated words.  The struggling readers  can practice words from Frys high-frequency words if they are purposefully placed for meaning placed into the phrases, such as a hundred ships  pulled  (from Frys 4th 100-word  list). Such phrases can be read aloud for accuracy and fluency as part of a vocabulary activity that is based in a disciplines content. In addition, a literacy strategy for struggling readers comes from Suzy Pepper Rollins book Learning in the Fast Lane.  She introduces the idea of TIP charts, used to introduce a lessons vocabulary. Students may have access to these charts that are set up in three columns: Terms (T) Information (I) and Pictures (P). Students can use these TIP charts to increase their ability to engage in accountable talk in expressing their understanding or summarizing the reading. Such talk can help develop the speaking and listening  skills of struggling readers.   Read aloud A text can be read aloud to students at any grade level. The sound of a human voice reading a text may be one of the best ways to help struggling readers develop an ear for language. Reading aloud is modeling, and students can make meaning from someones phrasing and intonation when reading a text. Modeling good reading helps all students while it provides access to the text being used. Reading aloud to students should also include think-aloud or interactive elements. Teachers should focus intentionally on the meaning â€Å"within the text,† â€Å"about the text,† and â€Å"beyond the text†   as they read. This kind of interactive read aloud means stopping to ask questions to check for understanding and allowing students to discuss meaning with partners. After listening to a read aloud, struggling readers can contribute the same as their peers in a read-aloud.   Illustrate understanding When possible, all students should have the opportunity to draw their understanding. Teachers can ask all students to summarize the lessons â€Å"big idea† or major concept can be summarized. Struggling students can share and explain their image with a partner, in a small group, or in a gallery walk.They may draw in different ways: To add to a pictureTo create an original pictureTo draw and label a pictureTo draw and to annotate a picture Literacy strategy matches objective Strategies used to support struggling readers should be tied to the lessons objective. If the lesson objective making inferences from a fiction text, then a repeated read aloud  of the text or selection of the text can help struggling readers to determine the best evidence to support their understanding. If the lesson objective is explaining the impact of rivers on developing a  settlement, then vocabulary strategies will provide struggling readers with the terms needed to explain their understanding.   Rather than try to address all of the needs of a struggling reader through modification of remediation, teachers can be purposeful in lesson design and selective in their choice of strategy,   using them individually or in a sequence:   starter activity, vocabulary prep, read-aloud, illustrate. Teachers can plan  each content lesson to offer access to a common text for all students. When struggling readers are given the chance to participate, their engagement and their motivation will increase, perhaps even more than when traditional remediation is used.

Income Elasticity of Demand

Income Elasticity of Demand A Beginners Guide to Elasticity: Price Elasticity of Demand  introduced the basic concept and illustrated it with a few examples of price elasticity of demand.   A Brief Review of Price Elasticity of Demand The formula for price elasticity of demand is:   Price Elasticity of Demand (PEoD) (% Change in Quantity Demanded) à ·Ã‚  (% Change in Price) The formula quantifies the demand for a given as the percentage change in the quantity of the good demanded divided by the percentage change in its price.   If the product, for example, is aspirin, which is widely available from many different manufacturers, a small change in one manufacturers price, lets say a 5 percent increase, might make a big difference in the demand for the product. Lets suppose that the decreased demand was a minus 20 percent, or -20%. Dividing the decreased demand (-20%) by the increased price (5 percent) gives a result of -4. The price elasticity of demand for aspirin is high a small difference in price produces a significant decrease in demand.   Generalizing the Formula You can generalize the formula by observing that it expresses the relationship between two variables, demand and price. A similar formula expresses another relationship, that between the demand for a given product  and consumer income Income Elasticity of Demand (% Change in Quantity Demanded)/(% Change in Income) In an economic recession, for example, U.S. household income might drop by 7 percent, but the household money spent on eating out might drop by 12 percent. In this case, the income elasticity of demand is calculated as 12 à · 7 or about 1.7. In other words, a moderate drop in income produces a greater drop in demand. In the same recession, on the other hand, we might discover that the 7 percent drop in household income produced only a 3 percent drop in baby formula sales. The calculation in this instance is 3 à · 7 or about 0.43.   what you can conclude from this is that eating out in restaurants is not an essential economic activity for U.S. households the elasticity of demand is 1.7, considerably great than 1.0 but that buying baby formula, with an income elasticity of demand of 0.43, is relatively essential and that demand will persist even when income drops.    Generalizing Income Elasticity of Demand Income elasticity of demand is used to see how sensitive the demand for a good is to an income change. The higher the income elasticity, the more sensitive demand for a good is to income changes. A very high-income elasticity suggests that when a consumers income goes up, consumers will buy a great deal more of that good and, conversely, that when income goes down consumers will cut back their purchases of that good to an even greater degree.   A very low price elasticity implies just the opposite, that changes in a consumers income have  little influence on demand. Often an assignment or a test will ask you the follow-up question Is the good a luxury good, a normal good, or an inferior good between the income range of $40,000 and $50,000? To answer that use the following rule of thumb: If IEoD 1 then the good is a Luxury Good and Income ElasticIf IEoD 1 and IEOD 0 then the good is a Normal Good and Income InelasticIf IEoD 0 then the good is an Inferior Good and Negative Income Inelastic The other side of the coin, of course, is supply.

International relations Essay Example | Topics and Well Written Essays - 750 words

International relations - Essay Example After all, since the adoption of the UN Charter in 1945, the world has seen plenty of wars that the world body failed to avert. At the same time, however, students of the UN are inclined to give it the credit for the decreasing intensity of the wars. Although realists see the laws of power politics as relatively timeless and unchanging, liberal theorists generally see the rules of IR as slowly, incrementally evolving through time and potentially becoming more and more peaceful. (Joshua S. Goldstein and Jon C. Pevehouse. â€Å"International Relations, 8/e†. 2008) This evolution results primarily from gradual buildup of international organization and mutual cooperation (reciprocity) and secondarily from changes in norms and public opinion (identity)†¦ â€Å"We are not doomed to a world of recurring war but can achieve a more peaceful world,† says Goldstein and Pevehouse. For example, in recent years a strong trend toward fewer warts has become evident (Human Security Centre. Human Security Report 2005: â€Å"War and Peace in the 21st Century; 2006). For instance, to many Americans the world seems more war-prone and violent than ever because the United States is at war on a scale not seen since Vietnam. Yet, for the world as a whole, the current period is one of the least warlike ever, with fewer and smaller wars than in the past. â€Å"In the first half of the 20th century, world wars â€Å"killed tens of millions and left whole contents in ruin; in the second half, during the Cold War, proxy wars killed millions, and the world feared a nuclear war that could have wiped out our species. Now, in the 21st century, wars like those in Iraq and Sudan kill hundreds of thousands.† (Goldstein and Pevehouse) The late 1990s and the early 21st century saw termination of vestigial remnants of Cold War era, such as in Angola, Northern Ireland, Guatemala, and southern Sudan, following South Africa and Mozambique earlier in the 1990s. Most wars that erupted after the end of
