Rap To Teach English As Second Language

Rap To Teach English As Second Language Introduction Music is part of popular culture. Language teachers have been integrated music and language learning in the classroom for many years. For example, using the song Yesterday from the Beatles to teach past tense. If music and songs can help learning English as a second language, English teachers in Hong Kong should be encouraged to use rap songs as a tool to teach English as a second language in the classroom. According to the Oxford English Dictionary, rap is a style of popular music developed by New York Blacks in the 1970s in which words are spoken rhythmically and often in rhyming sentences over an instrumental backing. In the early 1770s, Clive Campbell (Kool DJ Herc), a Jamaican immigrant, introduced the sound system from reggae music (Njubi, 2001). By combining the English sound system and other African-American linguistic features, rap has become a unique voice for the African Americans. When we talk about rap songs, we must mention hip-hop culture. Hip-hop is a cultural movement originated from the Bronx (a poor gang-oriented neighborhood) in New York City during the 1970s by African American. Njubi stated that hip-hop is clearly one of the most significant youth cultures as it has influenced what young people wear, how they talk and even the way they walk. It has also received significant attention from scholars and politicians. Hip-hop has been a major literacy force for over twenty years (Morris, 2002) because it has created rap as an important music genre. English teachers around the world are trying to use rap as an educational tool to promote English (Pennycook, 2003) because of its fast spoken lyrics. However, many teachers in Hong Kong are reluctant to use rap songs in the classroom because most of them think the lyrics either violent or sexual, and some think the materials are too black or Americanized (Low, 2009). In the following, we will discuss how rap songs can be an effective language learning tool to motivate students in learning English as well as increase their awareness of cultural differences. Why do we use rap songs for language teaching and learning? Music is accessible because of the technology such as iTunes and iPod. Since 1937, using folk, classical and pop music to teach English as a second language has been documented by educators in various professional journals (Sposet, 2008). Through music, students can improve their speaking skills, learning and understanding grammar, enhance their writing skills and increase their culture awareness (Peregoy and Boyle 2008; Saricoban and Metin 2000; Iwasaki, 2009). Woodall and Zeimbroski (2002) stated that music plays an important role in language and literacy development because students can learn grammatical structure and develop natural responses and speech through songs. According to Schoepp (2000), the repetitive nature of many rap songs can help English learners to get familiar with new words and phrases as they can rhyme and sing along. Many rap songs, just like folk songs, follow a repeated verse and rhyme, and that makes them easy to follow (Saricoban and Metin, 2000). For teenagers, it is important to improve their listening and speaking skills, as well as their attention span and memory (Hilll-Clarke and Robinson 2003). Mithen (2006) stated that all individuals have a capacity to acquire language and are born with a basic instinct to appreciate music. Iwasaki (2009) also agreed that music is a powerful medium to motivate students to learn a second or foreign language. When students listen to songs and sing along, the experience is enjoyable and stress-free, it can help second language learners to acquire the language more naturally and effectively. Perry (2004) also agreed with linguist Geneva Smitherman that rap lyrics are usually humorous, ironic, punning, teachy but not preachy. If according to Abbotts (2002) theory, repetition can help build language and fluency, then rap songs can definitely help stimulate second language learning because of its repetitive format. Also, by using the chorus in the rap songs, it can help students to learn syntax and lexical items easily and apply them in their daily conversations. Using music to enhance our memory and learning Mithen summed up three similarities between music and language : MUSIC LANGUAGE lyrics words singing speaking rhythm and melody intonation and stress time Lake (2002) found out language and music are closely tied together in the brain by pitch, rhythm and syntactical phrasing. When students understand the connections, they can acquire, process and produce English naturally. Neurologists have found musical and language processing in the same area of the brain (Maess Koelsch, 2001). To illustrate the strong connection between music and learning, Strickland (2005) conducted a very interesting and valid experiment. He asked a group of students if they could remember the words in ten poems. Then, he asked how many words they could remember in ten songs. Without much surprise, there were more hands go up the second time. It clearly proved that music has played a very important and memorable role in language learning. Medina (2002) agreed that we have good memory with music because all those repetitive words and rhythm stay in our head even after the English lesson. When we add rhythm and melody into language, it will help us to transfer words into long-term memory. Medina concluded that it is impossible to acquire language without memory. Using rap to teach poems and pronunciations According to Renegade (2002), the strongest poetic influence on rap is popular poems with four bears per line, for example, Eenie meenie, mynie moe, Catch a tiger by the toe. With all those rhyming, cross-rhyming, metaphor, symbolism and simile, rap can be a preferred literacy teaching tool to teach English as a second language. Renegade noticed rap lyrics are written according to highly structured rules. There are two forms of rap lyrics: Rhyme and rap song. A rhyme is a single long stanza, often a narrative and the writer can write as many as he / she wants, whereas a rap song borrows its structure from a popular song with repeating chorus in between. Renegade also observed that rappers have been using rap as a poetic tool because it has a strong emphasis on assonance, consonance, and combinations with end rhyme. Rappers like to use simile, metaphor, invention and reinvention of words to spark off new interest in poetry. In other words, using low culture to teach high culture. In 2002 and 2004, Low worked with a creative writing teacher to develop and teach spoken word poetry curriculum. The initial curriculum was only a seven-week program but in 2004, it became a long-term course. Low concluded the success of the program as a literacy of LIVING experience because students were able to use rap as a platform to speak inside and outside the classroom. Strickland also agreed that students are natural poets, and poetry is meant to be performed. Lake observed a strong connection between intonation and music. He noticed students interested in symbols and images, and that means they are more likely to be stimulated by audio or visual. He compared words, feeling, pitch and stress with musical expression. He concluded that speech without music is like language without heart because both music and language express emotions and convey messages. Through rap songs, students can learn pronunciation, intonation, stress, accent, pitch, tone, melody, rhyme, rhythm and fluency. Students who enjoy singing, chanting, lip syncing or mouthing along can improve their pronunciation skills and practice linking and reduction when speaking English Using rap to enhance reading and writing skills To be a good rapper, one must be able to use his / her voice to write, have good memory and reinvent rhymes spontaneously. Rap music encourages teenagers to write because it reflected the writers inner speech and images in their mind. For example, in Lows spoken word poetry school project, students in the class were able to write powerful and thoughtful poetry for the first time because they were inspired by rap. A lot of students in Hong Kong hate writing because expressing themselves in a second language is already difficult, and writing in a second language is even more challenging. Students need to have a reason to write, and that reason will become their motivation. Alvermann, Hagood and Williams (2001) shared a case of a 14-year-old Grade 8 / F. 2) African American boy who scored the lowest on the districts standardized reading test. The school boy loves rap, so Williams asked him to write to him about his favorite rap artist. The boy wanted to have more factual information about his favorite rap artist. Williams agreed to help the boy with his project, and he asked the boy to e-mail him regularly and keep him informed of his findings. The boy demonstrated that he was a capable reader because he searched for specific information through different websites, and he was a capable writer because he used popular culture texts in his writing. Instead of just giving information to the school boy, Williams guided him throughout the project and made him an independent learner, and enhance both of his reading and writing skills, not to mention giving him a higher self-esteem and more self-confidence. Iwasaki (2009) stated that rap songs have natural language and it can help students to process the meaning of words under an authentic environment. In Weinsteins (2008) study, she found many teenaged students have demonstrated sophisticated understanding of literary features through rap, for example, figurative language. Rap can help students, especially the social marginalized ones to write lyrics that can reflect social, economic and racial problems. Teenagers enjoy writing lyrics for rap because it is a channel for them to prove and establish their identity, an outlet for them to express their anger and frustrations about school, community, social norms, confusion and desire. Lake suggested that students are already heavily exposed to popular culture and music of their first language, it is likely that they are going to be curious about the popular culture and music of their second or foreign language as well. The purpose of writing for teenagers should not be just classroom based, it should be included a great variety and popular culture related topics. Despite worrying about low test scores, teenagers will be more willing and eager to try because when they see the purpose, they can produce quality work and invest their time in it. Through rap songs, teachers can further illustrate and explain grammatical structures to students. Based on Schoepps observation, songs can help students to develop a natural ability to use the target language in the right situation. When students are exposed to repetitive phrases in the right context, they can remember the language and apply it automatically. Using rap to help student to communicate with the world Iwasaki noticed that while students are gaining linguistic knowledge through rap songs, they are gaining the cultural knowledge at the same time as well. The lyrics always tell us something about the history, culture, thinking and attitude of a society. As Pennycook concluded that rap is a global phenomenon involving language use. Pennycook noticed rap has always helped the spread of English globally, especially to countries where English is a foreign language, like Japan and Korea. Mitchell (2001:1-2) argued that hip-hop and rap only belong to African-American culture. In fact, it has brought youth from around the world closer. It is not about where one comes from or which social class one belongs to, but what one can do with the language. Iwasaki believes culture, like music and language, develops and changes. Therefore, popular culture is a channel for the mass to express themselves and for those who want to release pressure from the society. Allowing students to expose to both mass and popular culture will help them to develop cultural awareness of others and their own. Pennycook argues despite the lyrics in rap contains highly controversial topics and expressions, it also communicates meaning on a global scale. Rap is not just about the blacks in the U.S. but a common language shared by a lot of Asian countries like Japan, Korea and even Hong Kong. s we are all going global, our ability to communicate and knowing each others language and music will help us to understand each others customs and traditions much better and faster, thus, avoid conflicts and misunderstanding. Based on the evidence above, few would agree with Schumanns hypothesis in 1976 that the greater the social distance between two cultures, the more difficulty the learner would have in acquiring the target language. Negative impression towards rap A lot of English teachers are reluctant to incorporate rap in their class because when they think of rap, they will have all these negative images villains, gangsters, low culture, low education, guns, drugs, blood, violence, sex, materials and bling bling. They do not know how and where to find the GOOD rap songs with positive meaning. Weinstein (2006) criticized the highly sexual nature of many popular rap songs often gives damaging images of black men and women. The music videos always emphasizes on violence and drugs which also reinforce stereotypes of Blacks and Black youths where they are seen as dangerous, immoral and anti-social. However, Iwasaki argued that any music-based lesson could become a disaster without any thoughtful selection and preparation. Same for Kolozes argument, people wrote songs about drugs, life in the ghetto, rebellion and sex in popular songs since the 1950s. Iwasaki urged teachers to actually make use of those discussions to enhance students critical thinking while acquiring a second language. According to her theory, without general culture knowledge and some social and political awareness, one would find it difficult to participate in common and meaningful topics that a second or foreign language can offer. Some teachers may think some rap songs are inappropriate for classroom use, but the massive influence of rap and hip-hop music around the world has to be considered and noticed. Just like all other popular culture and media, it has its positive and negative influence. Lake also agreed that it would be a foolish if teachers do not use music to take advantage of the positive influence of music as a teaching tool. Selecting a rap with a positive message and the right attitude can enhance English learning as well as social awareness. English teachers need to realize that each rap has a message to spread out. As Music in a universal language, most raps are trying to solve race, class and religion problems that face by the youth (Njubi, 2001). For example, Where is the Love? by Black Eyed Peas. The rap is about the U.S. after the 911 tragedy and calling for U.S. army withdrawal from Iraq. The rap song was the longest-serving British No. 1 in five years and the best selling record of 2003 in the U.K. The group performed the song at the 2004 Grammy Awards, where it was nominated for The Record Of The Year (Wikipedia). This rap was so popular and moved so many people around the world because it is a social-conscious rap. It focused on upright and political awareness. Despite social and political implications, raps do give a voice to young people and inspire them. Teachers should involve their students in the selection process because when they hear something they can relate to, it will motivate them to learn. Challenges The arguments for incorporating popular culture into traditional curriculum are quite compelling and have generated a lot of noises and controversies. A lot of teachers and educators are filled with confusions and anxiety. Morrell (2002) understands teachers feeling daunting about using popular culture because of a lack of understanding. Rap has always been controversial because it is the rappers are expressing opposing views to the dominant culture. By helping students to understand the content can help them to make a meaningful connection between language and culture. Allowing students to be exposed to both mass and popular culture will allow them to think about their own cultural beliefs. School education should incorporate elements and materials from popular culture. Just like what Itoi and Inose (2008) mentioned that teachers should encourage students to think critically around their surroundings and become an independent thinkers. Students can gain insights about the songs by understanding or implying what they hear. Situations in songs are usually open to interpretation, so students can exercise their imagination and express their opinions freely. Conclusion It is the teachers ultimate goal to inspire students to develop their sills and interest in English DURING and AFTER class. Music is one way to create memorable lessons and spark curiosity beyond formal language lessons. Music is a highly relevant source of language outside the classroom. Integrating music into teenagers everyday activities promotes literacy development, particularly for English learners. It is a way for students to experience rich and complex language in a relaxing and entertaining way. A learning environment filled with music will generate interest, encourage creativity and positive learning attitude. Plato once said, Music is a moral law. It gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything. Activity 1 Where is the love? by Black Eyed Peas Total class time : 60 minutes Warm up (12 mins) Use the rap song Where is the Love?

Teacher will count the number of hip-hop caps and write the result on the whiteboard and see which group is the audiences favorite No formal assessment is needed at this stage as this practice is to help the slower and quiet / shy students to build up their confidence. However, teacher will ask students randomly and see what and why they like or do not like about certain groups performance. Post class activity : A group project Time given: 10 days Teacher will spend 10 to 15 minutes explaining this group project Students need to work in a group of 4 Students need to find a controversial social or political topic in Hong Kong through the South China Morning Post or other English news media on the internet Students need to express their opinions about that topic by writing new lyrics that will fit into the rap song of their choice The rap song must be either from the U.S. or Hong Kong Students need to perform and record their NEW RAP and post it on YouTube.

Pretty Little Liars Essay

Are Pretty Little Liars good at keeping their dirty secretes? Pretty Little Liars a favorite ABC Family series is built around five teenage friends, until one goes missing and is found dead. It has a strong hint of supernatural force that mean no good. It makes most popular vampire romances look anemic. Because of a popular series of HarperTeen books by Sara Shepard, Pretty Little Liars follows the nervous lives of four girls in Rosewood, Pa. It’s a small town and these girls seem to have it all and that sets it up for an even better drama, when we start to see they also have secrets. The season premier starts with the disappearance and apparent death of the fifth girl in the circle, Alison DiLorentis. If the PLL series were traditional, Alison, Sasha Pieterse would have been the sweetest girl in school and no one could imagine anyone wanting to hurt her. If that’s what you’re expecting here, you’re wrong. Alison was a bitchy gossiper, backstabber and cruel practical joker. In any case, they were all together the night she disappeared and we join the story a year later, when free spirit Aria, Lucy Hale, nerdySpencer,TroianBellisario, crazy Hanna, Ashley Benson and jock Emily Shay Mitchell have drifted apart. Drug and alcohol use, foul language, scanty clothing, sexual innuendo and some passioate make-out scenes and homosexuality all make Pretty Little Liars a series that keeps viewers on their feet. Every episode leaves you with a cliffhanger. They run into each other in random chance encounters, however, that suggest each is harboring dark secrets, some related to Alison and some not. Since they apparently weren’t into deep sharing when they were all best friends then, they aren’t spilling now. Except they have two problems. A local cop is determined to find out what happened to Alison. Second, the girls all start getting mysterious messages that suggest some supernatural force knows all the secrets and could and sometimes do expose them to the public. Could the messages be coming from Alison? But isn’t that impossible? What kind of phone network lets you keep texting when you’re dead? I’d say that’s beyond 4g. It’s one thing to talk with your friends about lacrosse practice or the hot guy in the French class. It’s something else when you’re trying to figure out what happened to your disappeared friend, and how disappeared she really is. â€Å"Pretty Little Liars† is good at making us care about the girl’s lives. It keeps us thinking each week as to what might happen the next.

Reason for Seeking a College Degree

The purpose of this essay is to discuss why I chose to seek a college degree, my learning style as discovered by the results of questionnaires, and the fact that I feel the results are accurate for me personally. Everyone has their own individual reasons for pursuing a college degree. For me, it is the desire to become a state Game Warden after retiring from the military. Being a state Game Warden requires that I have a degree in the biological or wildlife sciences. In a profession like this, it is important that one has a clear and concise understanding of wildlife biology at a collegiate level.To be a viable candidate in this profession, a college degree is necessary to present myself as a competitive individual for the job I am seeking to fill. Whether or not I have on the job training or experience, the college degree will show that I have the knowledge base to help me succeed as a warden. The end goal in my pursuit of a college degree is to not only broaden my scope of knowledge and skills, but to unlock career aspirations that would otherwise be unattainable for me without a degree. But before I put the cart before the horse, graduating with degree in hand requires I truly know myself inside and out.Basically I need to understand what my personal learning style is. Learning styles are not exactly chosen, they are natural and inherent to each learner. According to Felder & Soloman (n. d. ) there are several different learning styles: Active, Reflective, Visual, Auditory, Tactile, Sensing, Intuitive, Verbal, Sequential and Global. To find out what kind of learner you are, a simple questionnaire or quiz can be taken to narrow these options down. In taking Felder & Soloman’s Index of Learning Styles Questionnaire (n. d. and the Learning Style Inventory (Penn State, 2010) questionnaire, I have discovered that I am an active learner and a visual learner. An active learner is one who gravitates toward interpreting, comprehending, and retaining information in a â€Å"hands on† or active fashion. In other words they discuss or apply and explain the information to others (Felder & Soloman, n. d. ). The degree program I am enrolled in is online; which presents me with challenges and difficulties in using the active learning style that I normally rely upon.An alternative to active learning for me is visual, which will serve me well because online course material is something I can see to interpret and retain. Visual learners are those who absorb and maintain information efficiently through methods such as charts, diagrams, pictures, films or demonstrations (Felder & Soloman, n. d. ). Suggestions for success as a visual learner include writing out ideas and information for memorization and fully utilizing all course materials, whether they are maps, flashcards, charts or filmstrips (Penn State, 2010).I am someone who always reads the directions prior to completing any task, therefore this fits me perfectly. I fully agree with the r esults of these questionnaires. I am a mechanic- someone who works day in and day out with my hands. The things I am trying to accomplish or figure out require me to read texts, diagrams and pictures and solve the problem using these resources. I also discuss and apply the information found with those who are masters of the mechanic profession. My reasons for seeking a college degree are simple.I need to hold at minimum at Bachelor’s in the wildlife or biological sciences to reach my goal of being a state Game Warden after retirement from the military. To be successful in this means that I understand I am a visual and active learner, as realized after taking the learning styles questionnaires. References Felder, R. M. , & Soloman, B. A. (n. d. ).
