Teaching Learners Develop Their Students Oral...
The materials, activities, exercises, and digital tools in the project can help Chinese EFL teachers develop their studentsââ¬â¢ oral proficiency. In addition, with authentic learning materials and speaking practices, the project is designed to help English learners develop their communicative abilities. English teachers in China may refer to this curriculum in designing their own lessons for oral practice. English teachers in China can find some inspirations from this project when they want to use some speaking activities. This project may benefit EFL or ESL teachers who are teaching in a communicative classroom. EFL teachers, as well as ESL teachers, can use the activities in the project to practice studentsââ¬â¢ oral English. Also, English teachers can use some exercises in the project to assess studentsââ¬â¢ oral proficiency and design a curriculum for instruction based on the assessments. Stein (1999) said that oral proficiency refers to the ability that helps people to communicate effectively and accurately in the target language. English teachers in China, who want to create an authentic learning environment for the learners, can use the authentic materials in the curriculum or refer to the curriculum to design their own. By learning the curriculum in this project, EFL learners may develop their vocabulary, English skills and technology skills. If they are going to study in the U.S., the curriculum can help them increase their English comprehension skills and the skills ofShow MoreRelatedEnglish As A Second Or Foreign Language Essay1131 Words à |à 5 Pagesand teaching (Sun, 2013).

Worship of Nature Free Essays
The Worship of Nature John Greenleaf Whittier, famous poet in the ninetieth century, has shown throughout the poem, The Worship of Nature, a splendid explanation of how the natural world relates to us in both a physical and a spiritual sense. A spiritual sense that the word ââ¬Å"Worshipâ⬠deals with the ideal belief that there is or was something in which created all things. Also, society and order can be compared to nature in such a way that nature is everything that is, was, or will be created. We will write a custom essay sample on Worship of Nature or any similar topic only for you Order Now Within the rhyme scheme of the Shakespearian sonnet, John Greenleaf Whittier has focused this poem under the theme of Creator and his Creation. Beginning his first stanza with: ââ¬Å"HE harp at Natureââ¬â¢s advent strungâ⬠(Nature line 1), Whittier emphasizes ââ¬Å"HEâ⬠in which it represents God harp or sculpting ââ¬Å"Nature. â⬠In this sense, Nature represents Godââ¬â¢s creations. As you progress farther through the poem some common elements of nature for example: life, death, water, earth, fire, and air. The ocean looketh up to the heaven, / And mirrors every starâ⬠(Nature line 7-8). These lines implies that mimicking others is a waist because it impossible for a copy which mirrors another to become the original. Combining Godââ¬â¢s creations and mimicking others, John Greenleaf Whittier sets a tone of holy and sanctifying. John Greenleaf Whittier uses the Shakespearian sonnet to his advantage by staging the first two lines into a cause and the la tter into an effect. It may be easiest to relate this theory to the last stanza. Music is a reoccurring component of this poem that refers back to the first stanza about God being the creator playing a harp making a beautiful symphony for all of his creations. Whittier has a very strange order in his poem but it makes sense at the end when he relay all together by implying that everything takes it own course and continues to move forward since the beginning of time which is eternity when talking about God. To put it briefly, John Greenleaf Whittier wants us understand that we must not live others lives, be ourselves and prosperous. How to cite Worship of Nature, Papers

Benzene and Activating Group free essay sample
In the mechanism, the alkene in the benzene ring attacks the Br2 group leaving a carbocation intermediate and a bromine anion. The Br2 was in an HBr solution, which used as a catalyst similar to FeBr3. The bromine anion then deprotonated a beta hydrogen, forming HBr and a benzene ring with the activating substituent and bromine. This reaction could be repeated up to two more times based on the strength of the orthro/para directing group. As a result, there were many possible different products when the aromatic compounds underwent bromination. For aniline, the prediction was that the product would be 2,4,6-tribromoaniline because anime was a very strong activating group that reacted strongly with halogenations reactions in general. For phenol, the hydroxy group was also a ring activating and electron donating group. A disubstituted bromine product was predicted because the hydroxy group was not as powerful as the amide. Anisole also had an activating group in a methoxy group and the prediction was from the anisole bromination reaction would be a disubstituted product. We will write a custom essay sample on Benzene and Activating Group or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Lastly, for acetamide, the amide group was considered to be not a strong activating group compared to the anime, hydroxy, and methoxy groups because of the fact that the electrons were not localized in the amide due to resonance. As a result, this reduced the activation of the benzene ring and the predicted product was 4-bromoacetanilide. Mechanism (for acetanilide): Results: Compound| Melting Tempeature (degrees Celsius)| Product (g)| Anisole| N/A| oil| Aniline| 119-120; 116-117 | 0. 116g; 0. 010g| Phenol| N/A; 36-51| 0. 325; 0. 007| Acetanilide| 166-168; 156-162| 0. 140g; 0. 111g| Calculations are posted at the back Reaction| Limiting Reagant| Actual Yield| Percent Yield:| Acetanilide| Acetanilide| 0. 140g| 65. 4 %| Discussion:The reaction that was done in lab was the bromination of acetamide. Overall, the reaction was pretty efficient as the percent yield of the reaction was 65%. Due to using a 10% v/v bromine solution, there was 0. 15 ml (0. 02 mol) of bromine in 1. 5 ml of the solution. Compared about 0. 135 g of acetamide used (0. 01 mol), there was an excess of bromine to react with the acetamide. As a result, there may have been not enough acetamide to react with bromine. The product also appeared to be somewhat water soluable, which reduced the efficiency. Also, the reactions done by the other groups had similar results or inefficient reactions that had small yields. Based on the melting point measurements in lab, the rankings in terms of reactivity were aniline, phenol, anisole, and acetamide. As predicted before, aniline was ranked as the most reactive because the product was 2,4,6-tribromoaniline, which had a melting point of 119-120 Ã °C. The second most reactive aromatic compound was phenol with products 2,4 and 2,6 dibromophenol at 36 to 51 Ã °C. The hydroxy group was a good activating group, but not strong enough to activate the benzene ring for a third bromination due to the deactivating effects of the added benzylic bromine. The third most reactive compound was anisole with an oil and possible products for this reaction could be 2 or 4 or 2,6 bromoanisole. Based on this reactivity, the methoxy group had steric bulk and the oxygen in the methoxy preferred to stabilize adjacent bromines. The least reactive compound was acetamide, with a product of 4-bromoacetanilide. The amide group in acetanilide was bulky, so preferring the ortho position would mean a more stable product with less steric interaction. Overall, the predictions in the theory matched besides the anisole. The results make sense because as the reactivity decreases, it was down to factors such as electron delocalization due to resonance, steric bulk, and bromine being a deactivator to the benzene ring. Sources of Errors: Sources of errors may result from not crashing the reaction with enough water and sodium bisulfite and not rinsing the product with water during vacuum filtration. Conclusion: The product obtained in the reaction was 4-bromoacetanilide and the order of reactivity of bromination was determined. Calculations: Mol of Bromine: 10% v/v = (0. 15 mL Br2) x (3. 11 g/mL) x (159. 81 g/mol) = 0. 003 mol Br2 Mol of Acetanilide: (0. 135g acetanilide) x (1 mol/135. 17 g) = 0. 001 mol acetanilide Acetanilide is Limiting Reagant. Theoretical Yield: (0. 135g acetanilide) x (1 mol acetanilide/135. 17 g) x (1 mol 4-bromoacetanilide/1 acetanilide) x (215. 07 g/1 mol 4-bromoacetanilide) = 0. 215g Percent Yield: . 140g/ 0. 215g= 65. 1%
