Write about Phonology and Phonetics


Each and every language had its own unique sound and sound sequences. However, the number of possible sound distinctions which can be made in any language in quite limited. When we listen to any speakers, we can realize that they have a distinct set of sounds and certain ways to put the sounds together. So all languages share at least some sets of sounds.

Phonology is a branch of linguistics which studies the sound systems of a particular language. The word phonology is derived from Greek word “phone” which means sound and logos which means science or knowledge.

It is just one of several aspects of language which is related to other aspects such as phonetics, morphology. It is the study of how sounds are organized and sound in natural languages and description of the systems and patterns of language.

The aim of phonology is to demonstrate the pattern of distinctive sound found in a language and to make general statements as possible about the nature of sound systems in the language of the world. It is concerned with the range and function of sounds in specific languages and with the rules which can be written to show the types of phonetic relationships that relate and contrast words and other linguistic units.

Phonology is the basis for further work in Morphology, syntax, discourse and orthography design. Therefore, it analyzes the sound pattern of a language by determining which phonetic sounds are significant and explaining how these sounds are interpreted by native speakers. It studies the speech sounds only within the limited context or systems of a certain language. It is concerned only with distinctive sounds that can make differences in meaning within a language. Such distinctive sounds which become meaningful units in larger units in a given language are phonemes. It is the smallest distinctive unit in phonology of language systems, another being syntax and yet another semantics which draws upon the finding of phonetics but it doesn’t deal with the phonic medium as such.

Then it seeks to discern the sounds made in all human languages. The identification of universal and non-universal qualities of sounds is a crucial component in phonology as all languages use syllables and forms of vowels and consonants. 
Syllables are involved in the timing space of speaker language since speaking each word takes a position of time. Syllables are units of measurement in language. Vowels allow air to escape from the mouth and nose unblocked while consonants create more covering of the vocal tract by the tongue. The heard friction i.e. a consonant is made from the air that can not escape as the mouth utters the consonant.

Phonemes are units of sound are a language that conveys meaning. For instance, changing a syllable in a word will change its meaning such as changing the “a” in “mad” to an “o” to produce “mod”.

A phone can also achieve no meaning by creating non-existent. Word such as by changing the “m” in “mad” or “mod” to a “j” to produce “sad” or “jod”. Phonemes differ from morphemes and graphemes. A morpheme refers to main grammar units while grapheme is the main unit of written language.

The proper pronunciation used in a language is a practical application of phonology. For example:- Phonology uses symbols to differentiate the sounds of a particular vowel.

Vowels are classified into ‘front’ ‘central’ and ‘back’ depending on the positioning of the jaw and tongue when the vowel sounds are made.
 Phonology also note lip position such as if the lips are spread out or rounded as well as if the vowel sound is long or short. The symbol for the vowel sound in words such as ‘chilly’ or ‘fin’ in phonology is /I/ and refers to a front short vowel spoken with a tongue in high position and spread lips.

Contrasting the symbol for the vowel sound in words such as “moon” or “blue” in phonology is /u/ and refers to a back, long vowel spoken with a tongue in high position still, but with sounded lips.
                                                                Phonetics
Phonetics is derived from Greek word ‘phone’ means “sound, voice”, is the science which studies the characteristics of human sound making especially those sounds used in speech and provides methods for their description, classification and transcription of all speech sounds of human beings. It comprises the study of the sounds of human speech and is concerned with the physical properties of speech sounds (phones), and the processes of their physiology production, auditory reception and neurophysiological perception.

Thus phonetics is the study of the production, perception and transmission of speech sounds of human language in general. Phonetics deals with the ways speech sounds of human languages are produced the physical properties of transmission and the conditions of their perception.

In fact, phonetics is the basis for phonological analysis which analyzes the production of all human speech sounds regardless of language. It is the study of the phonic medium. Phonetics is categorizes into three branches which are given as below:-
1.     Articulator Phonetics: - It is the study of the way speech sounds are made or articulated by the vocal organs. It investigates and classifies speech-sounds in terms of the way they are produced by the speech organs. Thus it is concerned with the articulation of speech. The position, shape, and movement of articulators or speech organs, such as the lips, tongue, and vocal folds.  
2.     Acoustic phonetic: - It studies the physical properties of speech sound as transmitted between mouth and ear. In terms of the physical properties of the sound waves that are created by the activity of the speech organs and travel through the air from speaker to hearer. It is concerned with acoustics of speech: The properties of the sound, waves, such as their frequency and harmonics.
3.     Auditory phonetics: - It studies the perceptual response to speech sounds, as mediated by ear; auditory nerve and brain. In terms of the way the speech sounds are perceived and identified by the listener’s ear and brain. So it is concerned with speech perception. How sound is received by the inner ear and perceived by brain.
 
Phonetics is the criterion with which we operate in the phonological analysis of languages. It is the study of the articulatory and acoustic properties of the sounds of human language. 
In contrast to phonetics, phonology,is the study of language-specific systems and patterns of sound and gesture, relating such concerns with other levels and aspects of language. While phonology is grounded in phonetics, it has emerged as a distinct area of linguistics, dealing with abstract systems of sounds and gestural units (e.g, phoneme, features, mora, etc.) and their variants e.g., allophones, the distinctive properties  which form the basis of meaningful contrast between these units, and their classification into natural classes based on shared behavior and phonological processes. Phonetics tends to deal more with the physical properties of sounds and the physiological aspects of speech production and perception. It deals less with how sounds are patterned to encode meaning in language (though overlap in theorizing, research and clinical applications are possible.

Introduction of Lesson Planning

Generally, the term Lesson planning refers to the plan for teaching. It is a systematic plan for teaching and preparation of the teacher before entering into the classroom. Harmer (1991) says that the lesson plan is the art of mixing techniques, activities and materials in such a way that an ideal balance is created for the class (p. 259).  A good lesson has two general principles as variety and flexibility. He further explains that variety means involving students in a number of different types of activity and where possible introducing them to a wide selection of materials. Similarly, according to Bhattarai (1986), “lesson plan is the teachers’ preparation of a particular teaching item to guide his pupils towards achieving a determined objective of language skill within a short class period” (p. 193). It enables the teachers to learn to organize and facilitate the learners in the classroom. Therefore, lesson plan is a plan which is planned for the classroom in such a way that helps the teachers to have balance in their teaching.
Ur (1991) says that various lesson, in addition being more interesting and pleasant for both teachers and learners is likely to endow for a wider range of learning style and strategies and may delay onset of fatigue by providing regular refreshing changes in the type of mental of physical activity demanded.
Components of a lesson plan
Rai (2002) says that lesson plan includes as many as twelve and as few as four. The most common among them are; teaching item, objectives, teaching materials, revision and warming up, presentation, practice activities and evaluation.
Generally the components of the lesson plan are:
Teaching items
Specific objectives
Instructional materials
Teaching learning activities
Evaluation
Homework
Importance of Lesson Planning for Language Teachers
Kitzlik (2008) states that lesson planning allow the teachers to explore multiple aspects of pedagogical content knowledge. While developing lesson plans, teachers get opportunities to think deeply about the subject matter, including the way the subject matter is represented in particular textbooks or in such aspects of the curriculum as standards and benchmarks. They also get enough time to develop pedagogical activities or methods that facilitate students to understand the subject matter. Finally, the teachers who develop lesson plan can contemplate what students know and how they may best understand the content. And then facilitate the students learning in different way according to the context and situation.
Doff (1988) thinks that writing a lesson plan aids the teachers to prepare the lesson; it helps them decide exactly what they will do and how they will do it. He also further explains that there is no ‘correct’ way to write a lesson plan, although a good lesson plan should give a clear picture of what the teacher intends to do in the lesson. The teachers write the lesson plan in the way they like. Therefore, the lesson plan lets the teachers know what kind of subject matter or content are they going to do and how they are going to do or what kind of activities they are going to use in the classroom to facilitate the students learning in the classroom. Without the lesson plan, there is less chance of teaching effectively and there is less chance of aiding the students in learning systematically.
Woodward (2001) focusing on the importance of a good lesson plan suggesting the following points:
a. Thinking things through before you teach helps to reduce feelings of uncertainty or panic and inspires you instead with a sense of confident and clarity.
b. It can inspire confidence in students who pick up a feeling of purpose, progression and coherence.
c. It helps you to understand what research you need to do.
d. It reminds you to marshal materials beforehand, and makes it easier for you to organize the time and activity flow in classed.
e. If at least some of the planning is shared with students, they too will be able to gather their thoughts before class.
f.Plans can be used in lessons to get things started, and prompt memory, and can help us to answer student questions.
g. Working on planning after lessons, as well as before, ensures that the class you are teaching gets a balanced mixture of different kinds of materials, content and interaction types throughout the course.
h. Lesson planning helps you to develop a personal style (p. 181)
Similarly, Stephens and Crawley (1994) says, “Lesson plans require teachers to plan, teach and assess the effectiveness of lessons, and have defined this requirement explicitly” (p. 52).  The further stated that lesson plans are useful to co-ordinate and teach courses of learning in
an engaging effective and appropriate manner, supported by selected resources including
information technology.
The Necessity of detailed Lesson Planning
Harmer (1991) explains, “Most experienced teachers do not write down what they are going to do in a detailed way” (p. 268). He further said that the detailed plan is necessary for two reasons. Firstly, the inexperienced teacher needs a clear framework of reference for the task of planning, and secondly the form of the plan forces the teacher to consider aspects of planning that are considered desirable.
Woodward (2001) describes that although you can make your lesson notes mentally, many teachers, whether novice or experienced do write them down. The act of writing or typing helps many to organize their thinking. The physical act and the slight of the page mean that you’ve usually partly memorized your lesson steps by the time you’ve finished writing. If you are a novice teacher, doing this a few times with the same instructional sequences will help you to remember them. Clarifying your thoughts by writing them down means students are less likely to get confusing or incoherent messages.
Rai (2002) states that that every teacher needs some kind of lesson plan: it may be detailed in case of new teachers, it may be just some points in case of the experienced one; it may not be in black and white in case of some genius teacher.
Butt (2003) opines that experienced teachers who know their students well, who have built a rapport with them over time and who have a good understanding of the resources in their subject department may give the impression that they can successfully teach lesson that have barely been planned at all.
Pokhrel (2006) has expressed that many experienced teachers often reduce lesson plans to a mental map or short outline. On the other hand, new teachers usually find detailed lesson plans to be indispensable. He further presented that all details should be written down to assist the smooth delivery of the content. The extent of the detail will vary depending on the number of years of experience that the teacher has and the number of times he/she has taught the lesson.
Objectives of the study
The main objective of the study is to find out whether the prepared lesson plan is implemented in the real classroom situation or not. However, the study had the following specific objectives:
a. To find out whether teachers can implement their prepared lesson plan or not.
b. To find out the factors affecting in implementing in their classroom.
3.2 Methods of Data Collection
The methods of data collection in this study included classroom observations, and the pos-teaching interview with the teacher. We decided to focus the observation on classroom activity and instructional structure because these aspects were what the teacher was concerned for the implementation of the lesson plan. We decided to videotape the class because this would enable us easily to go back to the data we wanted. Also, we were afraid that our presence might have an inhibiting influence on the existing patterns of classroom interaction. But there was no such situation.
Data Collection Techniques
In order to gather data, we used the following techniques;
Interview
To collect information, we interview the teachers to know about their preparation of lesson plan and its implication in the classroom to enable the learner’s in learning process. “The puropose of interviewing is to find out what is in or on someone else’s mind. The purpose of open-ended interviewing not to put things in someone’s mind but to access the perspectives of the person being interviewed”(Patton, 1990 as cited in Best & Kahn, 1999, p. 199). It is simply a device of gathering inforamtion form the participants.
Interviews are particularly useful for gathering the story behind the participant’s experiences. We chose the in-depth interview by which we tried to take hold of the subjective facts of the participants as Siverman (2000) states that the choice of the open-ended interview as the gold-standard of quantitative research is widely spread (as cited in Richards, 2003, p. 47). So, we used open ended questions which allowed the participants express and share their ideas and perceptions with the greater flexibility on Lesson plan and its implication.
Classroom Observation
Observation is another technique which we used to collect data. “Observation offers a researcher or an investigator the opportunity to gather “live” data from naturally occurring social situations; researcher can look directly at what is taking place in situ rather than relying on second hand accounts. It has potential to yield more valid or authentic data” (Cohen et al., 2007, p. 396). Thus the research can look directly at what is taking place in situ and collect more valid and authentic data from the direct observation in the field.
Therefore, to understand the context of events or situation we went to schools to observe the participants and tried to discover things that participants might not freely talk about in interview situations to move beyond perceptions based on data and to access personal knowledge of the participants. It enables the researcher to enter and understand the real situation that is being described. We interpreted the reality on what we saw and what the participants said. Denzin and Lincoln (2005) states that qualitative observation is fundamentally naturalistic in essence, it occurs in the natural context of occurrence, among the actors who would naturally be participating in the interaction and follow the natural stream of everyday life. Therefore, to explore the reality, we observed the English teachers classes in the natural setting and took information in descriptive form in the field.
Findings and conclusion
Based on the information generated from the interview and observation it was found that the lesson plan is implemented in the class but not exact it is developed. As one of the teachers has said in interview that it is implemented 50% sometimes and about 90% sometimes which helps us to say that if teachers prepare lesson plan, it is implemented and it enables the teachers to save the time. Regarding the hindrances in implementation of the lesson is that sometimes the teachers fail to implement completely the prepared plan which she or he has to deal with it in the next class as well. Because of this, the teachers fail to implement another lesson plan for the next effectively as planned. The levels of the students sometimes create difficulty in implementing the lesson plan. Similarly, the current issues happening in the context of surrounding. For example, as one of the teachers has said that she was unable to implement her lesson plan in the classroom as the students were curious to talk about the earthquake that occurred the previous night. She tried to convince the students to focus on their study of the subject matter but they were not ready to give attention towards their teachers teaching. Therefore, she happened to ask the students to write an essay on the same topic earthquake and she failed to use her lesson plan on that day.
Similarly, based on the observation of the classroom, it was found that thought the teacher had written some certain objectives and ways to doing activities, however the classroom activities and practice was totally different. For instance, in Pre-observation, the teachers said that she would divide the class into five groups and let the students read poem “The Paper Boat” for discussion. She also further said that she would ask the students to interpret it in their own way. But she did it differently in the real situation. She just asked the students to open the book and started reading poem line by line herself and explained to the students. Later on, when we did post-observation, she tried to explain the reason that the number of the students was large and when she tried to divide the class into group, the students started making noise. Hence, she tried to control the class herself. Therefore, If the teacher try to prepare and use the lesson plan it is possible for implementation in the real classroom though there are some hindrances.
