Q.1   Write a note on internal punctuations.


  • Punctuation: A Point of Order
  • Commas and Serial Commas
  • Colons and Semi-Colons
  • Dashes and Parenthesis
  • Bracketing and Ellipsis
  • Recreational Punctuation Use

This chapter is dedicated to the most commonly used—and, misused—forms of punctuation that go inside a sentence. If you’d like to learn about end punctuation—periods, question marks, and exclamation points—consult “Sentence Moods.” Answers to questions about markers—apostrophes, italics and quotation marks—can be found in “Showcased Nouns” as part of the discussion of quotations, titles, and other atypical noun phrases and clauses; bracketing and ellipsis are also part of that discussion.


If you’ve ever studied the movements of an orchestra conductor, then you know that the pointer means everything. A bad conductor can’t properly orchestrate the complex musical sounds, phrases, and movements unless she or he knows how to point. Different methods of pointing can signal changes and actions, and the precision of such signals translates into the exacting precision of the orchestration, itself. So it is with sentence punctuation. In fact, the verb “punctuate” derives from the Latin verb meaning “to point.” Words such as “puncture,” “punctual” and “punctilious” are related because they’re about being exact in the way they point—creating a specific point of entry, adhering to a specific point in time, following a specific point of law, and so on. I’ve been accused of being punctilious on occasion, but the point of punctuation is to point readers in the exact direction you want them to go. However, a change of “direction” in this sense could mean a lot of different things: a change of feeling, a change of idea, and change of tempo, and so on. Just as conductors need different techniques for pointing, writers need different marks of punctuation—different pointers—to direct readers correctly.


For that reason, we should begin with what students “point to” as the most common source of writing frustration and irritation, the damnable comma.




Let’s all pause to settle an important existential paradox: what came first, the chicken or the comma?

The Greek verb koptein means, “to smite” or “to cut off”; it comes from the Latin capo, the root word for the verb “caponize,” meaning “castrate”—which is how a poor, emasculated rooster running around with more than just its head cut off ends up on the menu as “capon.” At first glance, the word “comma” seems unrelated to any of this, except that it’s derived from the Greek komma, the process of stamping out and die-cutting coins. As a matter of fact, the Russian kopeck gets its name from koptein, the very action that snipped the rooster’s coin purse. Therefore, in a manner of speaking, the blade once used to stamp out the kopecks that paid the chef who butchered the capon that turned into lunch at a restaurant in Moscow, should make us pause to reflect the humble heritage of the comma.


Sketchy as this etymological journey may have seemed, it reinforces the most important role of the comma: to “cut off” and “stamp out.” You’ve already picked up this idea as you’ve refined your understanding of parts of speech and sentence mechanics over the course of the semester, for parts of speech gather into phrases and clauses that “cut off” other clauses and phrases to “stamp out” ideas, and they often do it by enclosing themselves in—yep!—commas.

While students often correctly interpret comma usage as a pause within the sentence, they frequently misinterpret what a pause actually is. For the record, then, a pause in a sentence happens when an idea is interrupted, not when, in your mind, you stop to take a breath. Pausing is a syntactical process, a way of cutting up a sentence to stamp out and arrange discrete ideas. Take, for example, the following random phrases:

an elegant woman
tossing topsy-turvy roses
into the fire
throws a fit
having a bad day


Each of these “stamps out” an individual idea; each contributes its kopeck’s worth of information. If you try to combine these into a sentence, however, some of them will link together to create more complete ideas, while others will still fit into the same sentence but interrupt the flow of those complete ideas:


Having a bad day, an elegant woman throws a fit, tossing topsy-turvy roses into the fire.
Tossing topsy-turvy roses into the fire, an elegant woman having a bad day throws a fit.
Having a bad day tossing topsy-turvy roses, an elegant woman, into the fire, throws a fit.
Into the fire, an elegant woman, tossing topsy-turvy roses, throws a fit, having a bad day.


Whatever arrangement you make, you’re forced to cut off one idea in order to stamp out another, and you need commas to let the reader know when to pause for that change of phrasing.

Phrasing and “clausing” are, not surprisingly, the main reasons to use commas. We set off direct address nouns and appositive phrases by commas, the phrasing of dates and addresses requires commas, placing of modifiers and modifying phrases before their subjects frequently resorts to commas, listing anything in a series of three or more expects commas, and the building of compound and complex sentences depends upon commas:


Direct Address:
“Janice, pass me the bread please.”
“I’ll ask Rex, the man with the answers, what we should do.”
Dates and Addresses:
“Max was born on December 18, 1954, in Mobile, Alabama, U.S.A.”
Modifying phrases:
“Running for his life, he turned down a dark alley.”
“He stopped to rest, exhausted by his ordeal.”
“To escape a fate worse than death, he kept to the shadows.”
“At the end of the alley, he found an unlocked door.”
Compound Clauses:
“Buy a man a fish, and he’ll eat for a day, but teach a man to fish, and he’ll eat for lifetime.”
Dependent Clauses:
“When the guest of honor arrives, let’s all shout!”
“They missed their connecting flight, which spells disaster.”
“I’ll finish this dessert for your sake, even though I don’t like sweets.”
Quotes and Dialogue:
“She took one taste and exclaimed, ‘Yuck!’”
Some Interjections:
“What, darn it all, are we going to do now?”
Items in a Series:
“Of faith, hope, and love, the greatest of these is love.”

For most of these, two factors, “pause” and “interruption,” determine the need for commas. Nowhere is this clearer than with modifying words, phrases, and clauses. Using commas to enclose or set apart dependent clauses and modifying words and phrases often relies on whether or not they come before the subjects they modify and whether or not they interrupt the flow of ideas. If so, this creates the syntactical interruption that you can “hear” as a pause followed by a change of thought. However, when these come after their subjects and an interruption is no longer there, a comma wouldn’t be necessary. Let’s take several examples from the list above to illustrate this:

“At the end of the alley, he found an unlocked door.”
“When the guest of honor arrives, let’s all shout!”


“He found an unlocked door at the end of the alley.”
“Let’s all shout when the guest of honor arrives!”


In these examples, moving the modifying parts after their subjects removes the interruption, and, as a result, no comma is needed. Some modifiers, however, are interruptive no matter where you put them, so they will always need commas to set them apart:

“Exhausted by his ordeal, he stopped to rest.”
“I’ll finish this dessert for your sake, even though I don’t like sweets.”
“He stopped to rest, exhausted by his ordeal.”
“Even though I don’t like sweets, I’ll finish this dessert for your sake.”

Once again, the factors of interruption and pause are at work, so commas are needed to enclose or set apart these ideas.


“Pause” and “interruption” are the rational side of comma use and, even if you can’t remember the rules of commas as they apply to specific phrases, you can at least deploy commas confidently if you follow these suggestions. At other times, though, comma use is strictly a matter of convention or tradition having nothing to do with reason—how we delimit information in dates and addresses, for example. Although the absence of logic in such cases might worry you, you can still take comfort in the fact that hard and fast rules still apply to these conventions, and rules can be used consistently and reliably once you memorize them. (Yes, that’s a strong hint.)


If you’d like to learn more about the conventional use of commas, see

    • “Noun Phrases and Clauses,”
    • “Showcased Nouns,”
    • “Conjunctions,” and
    • “Interjections.”


Serial Commas
“x, y, and z”

What do magazines, monogamists, and killing sprees have in common? Other than making you think of tabloid journalism, they all come as a series: serial publications include magazines, yearbooks, and many other periodicals, serial monogamy is the practice of having only one partner at a time, and a serial murderer kills again and again, and sometimes again. And, that last sentence has a heck of a lot of series in it, as well as a heck of a lot of commas. When a series is presented in writing, you need a system of commas to separate the items in a series. You’re already familiar with one of the major forms of serializing: compound sentences. Two or more independent clauses joined by coordinating conjunctions requires the use of a comma before each of those conjunctions. With compound sentences, though, two independent clauses are enough to imply a series. Inside a clause, however, we identify a series as three or more of—well, anything, really: three or more compound parts of speech, three or more items, phrases, even dependent clauses. Series, then, always implies three or more items arranged in a list.


The “serial comma,” also known as the “Oxford comma,” is the convention of putting a comma before the coordinating conjunction in the last item of the series:

Ben Franklin once wrote, “Early to bed and early to rise makes a man healthy, wealthy, and wise.”


In the example above, the compound infinitive phrases that make up the subject of the sentence have no commas to separate them, because they’re a series of two, not three or more. However, “healthy, wealthy, and wise” are a triplet, so the last word in the series, “wise,” is set apart with a comma and a coordinating conjunction. (Yes, you could make a convincing argument that the verb should be “make,” not “makes,” but that’s how Franklin wrote it—let it go for now.)


A serial comma is not always needed, nor wanted. Sometimes, your intention is to put two or more things at the end of a series that go together as a single concept. For instance,

The applicant described himself as knowledgeable, experienced, ready and willing.


Even though “and” appears to come right before the fourth adjective in a series, the turn of phrase “ready and willing” is of apiece, so you wouldn’t want to break it up with a comma. You might, instead, put an additional conjunction in the series:

The applicant described himself as knowledgeable, experienced, and ready and willing.


Some, however, would contend that two conjunctions this close to each other make for clumsy writing. I’m of a similar mind on this point.

On the other hand, in some cases if you omit the serial comma, you cause a double entendre, or worse:

He invited to his birthday party his mentor, his best friend and his sworn enemy.


Does this sentence mean that his mentor is also his best friend and enemy? Or, are they three different people altogether? Sometimes, without the serial comma, it’s hard to know if we’re dealing with an actual series or just another appositive phrase.


As you can see, the need for a serial comma ultimately comes down to the context and the type of list you’re composing.




The word “colon” derives from the Latin word classifying a part of a poem, called a “strophe.” (Yes, it’s related to the word “apostrophe,” among other things. In fact, this is probably the first time you’ve thought of a bowel movement as poetry in motion.) A strophe is a unit measuring structure in Greek poetry. The equivalent of this in grammar is the sentence clause. Colons play a major role in introducing other clauses and phrases, such as quotations. A full discussion of this topic can be found in “Noun Phrases and Clauses” as well as “Showcased Nouns.”


Colons are sometimes used after salutations and other notations in formal and business- style letters, but even in this case the purpose is to spotlight and introduce:

·         Attn: Selection Committee
·         Re: mergers and acquisitions
·         To Whom It May Concern:
·         Hello:
·         cc:
·         Word count:

Frequently, though, a colon comes at the end of an independent clause for one of two noble purposes: 1) to spotlight one major thing; or 2) to introduce a series of things. To understand this, you simply have to think of colons as the emcees of punctuation. At the crucial moment, an emcee does the job of announcing and introducing, using remarks like, “Ladies and gentleman, please help me welcome…!” Sometimes the show has only one main guest, in which case the emcee relinquishes the spotlight so that the main act takes over—that’s that. Other times, though, an emcee has to play host to a series of guests and must introduce them as separate but related acts; then, the emcee is responsible for coordinating the parts of a show, and making sure each part follows the same format.


Colons do the job of announcing and introducing, too. Sometimes they spotlight just one main idea, building up a bit of anticipation for it:


Membership in our club has but one strict and non-negotiable rule: no drama. Most dictionaries readily point out that “irregardless” is not a legitimate word: it’s a mixed- up blend of “regardless” and “irrespective.”


At other times, colons introduce a series of ideas, in which case the colon is responsible for coordinating each item, and making sure each follows a parallel format:


Drag artists have a tradition of choosing stage names that are double entendres: Tequila Mockingbird, Courtney Act, Amanda Hugginkiss, and so on.
Contrasting colors are always one of the three primary colors and the blend of the remaining two: red contrasts green, a blend of blue and yellow; blue contrasts orange, a blend of yellow and red; yellow contrasts purple, a blend of red and blue.


By “coordinating” and “parallel format,” I’m obviously referring to arranging elements in a series with parallel structure, which uses the same grammatical template for all the elements in the series. In the last example, above, each element in the series is a brief clause consisting of a color as its subject, the transitive verb “contrasts,” another color as its object, and an appositive phrase renaming the object:

subj. noun [color] + trans. verb “contrasts” + obj. noun [color] + appos. phrase


Colons are not interchangeable with semi-colons, even though they’re closely related. This is a common point of confusion, and knowing how to navigate past it depends upon your understanding of the part each plays in a sentence that includes a series. To put it succinctly, a colon classifies, and a semi-colon divides.



Semi-colons are a cross between a colon and a serial comma. (We could have coined them “commons” or “colas” if those words weren’t already taken, so the less-than- imaginative “semi-colon” will have to do.) “Semi” implies that a semi-colon does part of the work of a colon: while colons measure the full clause, semi-colons measure the elements within that clause (such as words and phrases). The sort-of exception to this rule is the compound sentence: semi-colons can sometimes replace coordinating conjunctions and their commas, when two or more independent clauses are joined together into a compound sentence. Though it’s by no means a law, in most cases a conjunctive adverb follows the semi-colon, to reinforce the close connection between one clause and the next:


With women banned from participating in Elizabethan theater, William Shakespeare became one of the first to use the acronym D.R.A.G., “dressed to read as girl”; however, he was far from being the first to cast males in female roles.


Furthermore, like the serial comma, the primary job of a semi-colon is to coordinate elements in a series, but only if they are introduced by a colon:


RuPaul identifies four qualities contestants should have to win his drag reality competition: charisma; uniqueness; nerve; talent.


As with serial commas, serial semi-colons are used only when three or more listed elements need separating. This is why I say, a semi-colon divides while a colon classifies. The colon tells us that what’s to come on the list is a collection of separate elements all deserving the same classification, but the semi-colon does the job of breaking down that classification into constituent parts. You can still use commas after a colon if the list is short and simple, but, with a colon, you’re granted the permission to use semi-colons instead. In the example above, the semi-colons could just as well have been commas, because it’s pretty clear where one item on the list ends and the next one begins:

RuPaul identifies four qualities contestants should have to win his drag reality competition, charisma, uniqueness, nerve, and talent.


Simple lists like the one in the example above can, without much confusion, be included as appositive phrases. (The list above renames “four qualities.”) However, with four or more items in the series, it’s a courtesy and a practicality to use semi-colons instead of commas. When you’re arranging a list of complex phrases, for instance, often you’re already using commas in other ways, so you need a different punctuation mark to show readers where these items are segregated from one another. Consider the following example:


Drag entertainment comes with several stereotypical and largely false perceptions: many people, especially heterosexual males, think you have to be gay to do drag, people assume doing drag is the same as being a transvestite, which has actually very little to do with most drag performance, and, probably even more commonly, people assume drag performers are transsexuals who have completed sexual reassignment surgery, which is not only rare, but, in fact, most drag performers exit the stage door styled to look like ordinary men.


Because of how many commas are used in this long-ish example, the sentence is not only comma-spliced in places, it’s rambling and confusing. Semi-colons would be a practical way to sort this out, separating the individual elements from one another in the list and letting the commas do other jobs within those elements:


Drag entertainment comes with several stereotypical and largely false perceptions: many people, especially heterosexual males, think you have to be gay to do drag; people assume doing drag is the same as being a transvestite, which has actually very little to do with most drag performance; and, probably even more commonly, people assume drag performers are transsexuals who have completed sexual reassignment surgery, which is not only rare, but, in fact, most drag performers exit the stage door styled to look like ordinary men.



Q.2   What is meant by transfer of information? How it can be achieved in language classroom?      


Transfer of Information

Have you ever learned to play a musical instrument? Imagine that you took guitar lessons when you were a child. If you learned to play the guitar, and now you wanted to learn a different musical instrument, do you think your guitar skills would hurt you or help you? When previous knowledge or skills help or hurt your ability to learn something new, that’s called transfer of information, and that’s the topic of this lesson.

Transfer of information is how skills or knowledge that students have learned about one topic affect their learning of skills or knowledge in another topic or area. Sometimes transfer of information can help students learn more quickly or more easily. However, in other circumstances, transfer of information can hurt learning. Let’s talk about several different kinds of transfer of information.

Positive, Negative and Zero Transfer

Transfer of information has been broken down into three major types, which include positive, negative and zero transfer.

The first type is positive transfer. Positive transfer is when knowledge or skills about a previous topic help a student learn a new skill or learn about a new topic. I remember that when I was a little girl I learned to play the guitar. A key step to learning any musical instrument is to learn how to read sheet music, such as how the notes spell the word ‘FACE’ on the paper, indicating the order of notes. So I learned how to read the notes to play the guitar. When I was a little bit older, I started to learn how to play the piano and I realized that the order of notes on the sheet music for piano was the same as the order for guitar! This transfer of information was therefore positive, meaning that the knowledge I had about playing guitar had helped me learn how to play the piano as well.

However, there can also be negative transfer. Negative transfer is when knowledge or skills about a previous topic hurt a student or interfere with learning about a new skill or topic. I have a personal story about negative transfer as well. When I was in college, I started to take martial arts classes in a particular art called Tae Kwon Do. When you learn Tae Kwon Do, you learn to point the toes of your front foot directly toward your opponent. However, a little later I started to take classes in a different martial art, called American Kenpo. In American Kenpo, you don’t point your front foot directly toward your opponent because it makes it easier for him or her to break your knee. But I had already formed the habit of pointing my toes, so the skills I had learned in my first martial art actually caused me problems in the second one. This is an example of negative transfer because the habits I had already formed caused me trouble in doing the second skill correctly.

The third and final type of information transfer is called zero transfer. Zero transfer just means that previous skills or information have zero effect on learning new skills or information. In other words, in this case the old information neither helps nor hurts the new information or skill. So, being able to play the piano would have no effect, good or bad, on your ability to learn the geography of Africa. Therefore, the information has zero effect.

Low-Road vs. High-Road

There’s a second way to think about different types of transfer of information in addition to the distinction of positive, negative and zero. This second way of thinking about it separates transfer into two groups, called low-road and high-road.



Q.3   Enlist the steps in planning a lesson. Further develop a lesson plan from English grade English tent book.         


A lesson plan is the instructor’s road map of what students need to learn and how it will be done effectively during the class time. Then, you can design appropriate learning activities and develop strategies to obtain feedback on student learning. Having a carefully constructed lesson plan for each 3-hour lesson allows you to enter the classroom with more confidence and maximizes your chance of having a meaningful learning experience with your students.

A successful lesson plan addresses and integrates three key components:

  • Learning Objectives
  • Learning activities
  • Assessment to check for student understanding

A lesson plan provides you with a general outline of your teaching goals, learning objectives, and means to accomplish them, and is by no means exhaustive. A productive lesson is not one in which everything goes exactly as planned, but one in which both students and instructor learn from each other.


Listed below are 6 steps for preparing your lesson plan before your class.


1. Identify the learning objectives

Before you plan your lesson, you will first need to identify the learning objectives for the lesson. A learning objective describes what the learner will know or be able to do after the learning experience rather than what the learner will be exposed to during the instruction (i.e. topics). Typically, it is written in a language that is easily understood by students and clearly related to the program learning outcomes. The table below contains the characteristics of clear learning objectives:

Characteristic Description
Clearly stated tasks Free from jargon and complex vocabulary; describe specific and achievable tasks (such as ‘describe’, ‘analyse’ or ‘evaluate’) NOT vague tasks (like ‘appreciate’, ‘understand’ or ‘explore’).
Important learning goals Describe the essential (rather than trivial) learning in the course which a student must achieve.
Achievable Can be achieved within the given period and sufficient resources are available.
Demonstrable and measurable Can be demonstrated in a tangible way; are assessable; achievement and quality of achievement can be observed.
Fair and equitable All students, including those with disabilities or constraints, have a fair chance of achieving them.
Linked to course and program objectives Consider the broader goals – i.e. course, program and institutional goals.

The Bloom’s Revised Taxonomy of Educational Objectives is a useful resource for crafting learning objectives that are demonstrable and measurable.


2. Plan the specific learning activities

When planning learning activities you should consider the types of activities students will need to engage in, in order to develop the skills and knowledge required to demonstrate effective learning in the course. Learning activities should be directly related to the learning objectives of the course, and provide experiences that will enable students to engage in, practice, and gain feedback on specific progress towards those objectives.

As you plan your learning activities, estimate how much time you will spend on each. Build in time for extended explanation or discussion, but also be prepared to move on quickly to different applications or problems, and to identify strategies that check for understanding. Some questions to think about as you design the learning activities you will use are:

  • What will I do to explain the topic?
  • What will I do to illustrate the topic in a different way?
  • How can I engage students in the topic?
  • What are some relevant real-life examples, analogies, or situations that can help students understand the topic?
  • What will students need to do to help them understand the topic better?

Many activities can be used to engage learners. The activity types (i.e. what the student is doing) and their examples provided below are by no means an exhaustive list, but will help you in thinking through how best to design and deliver high impact learning experiences for your students in a typical lesson.

Activity Type Learning Activity Description
Interaction with content

Students are more likely to retain information presented in these ways if they are asked to interact with the material in some way.

Drill and practice Problem/task is presented to students where they are asked to provide the answer; may be timed or untimed
Lecture Convey concepts verbally, often with visual aids (e.g. presentation slides)
Quiz Exercise to assess the level of student understanding and questions can take many forms, e.g. multiple-choice, short-structured, essay etc.
Student presentation Oral report where students share their research on a topic and take on a position and/or role
Interaction with digital content

Students experiment with decision making, and visualise the effects and/or consequences in virtual environments

Game Goal-oriented exercise that encourages collaboration and/or competition within a controlled virtual environment
Simulation Replica or representation of a real-world phenomenon that enables relationships, contexts, and concepts to be studied
Interaction with others

Peer relationships, informal support structures, and teacher-student interactions/relationships

Debate Verbal activity in which two or more differing viewpoints on a subject are presented and argued
Discussion Formal/informal conversation on a given topic/question where the instructor facilitates student sharing of responses to the questions, and building upon those responses
Feedback Information provided by the instructor and/or peer(s) regarding aspects of one’s performance or understanding
Guest Speaker Feelings, thoughts, ideas and experiences specific to a given topic are shared by an invited presenter
Problem solving and Critical thinking

Presenting students with a problem, scenario, case, challenge or design issue, which they are then asked to address or deal with provides students with opportunities to think about or use knowledge and information in new and different ways

Case Study Detailed story (true or fictional) that students analyse in detail to identify the underlying principles, practices, or lessons it contains
Concept Mapping Graphical representation of related information in which common or shared concepts are linked together
Real-world projects Planned set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations, either individually or collaboratively

The process of reflection starts with the student thinking about what they already know and have experienced in relation to the topic being explored/learnt. This is followed by analysis of why the student thinks about the topic in the way they do, and what assumptions, attitudes and beliefs they have about, and bring to learning about the topic.

Reflection journal Written records of students’ intellectual and emotional reactions to a given topic on a regular basis (e.g. weekly after each lesson)


It is important that each learning activity in the lesson must be (1) aligned to the lesson’s learning objectives, (2) meaningfully engage students in active, constructive, authentic, and collaborative ways, and (3) useful where the student is able to take what they have learnt from engaging with the activity and use it in another context, or for another purpose.


3. Plan to assess student understanding

Assessments (e.g., tests, papers, problem sets, performances) provide opportunities for students to demonstrate and practice the knowledge and skills articulated in the learning objectives, and for instructors to offer targeted feedback that can guide further learning.

Planning for assessment allows you to find out whether your students are learning. It involves making decisions about:

  • the number and type of assessment tasks that will best enable students to demonstrate learning objectives for the lesson
    • Examples of different assessments
    • Formative and/or summative
  • the criteria and standards that will be used to make assessment judgements
    • Rubrics
  • student roles in the assessment process
    • Self-assessment
    • Peer assessment
  • the weighting of individual assessment tasks and the method by which individual task judgements will be combined into a final grade for the course
    • information about how various tasks are to be weighted and combined into an overall grade must be provided to students
  • the provision of feedback
    • giving feedback to students on how to improve their learning, as well as giving feedback to instructors how to refine their teaching


4. Plan to sequence the lesson in an engaging and meaningful manner

Robert Gagne proposed a nine-step process called the events of instruction, which is useful for planning the sequence of your lesson. Using Gagne’s 9 events in conjunction with Bloom’s Revised Taxonomy of Educational Objectives aids in designing engaging and meaningful instruction.



Q.4   Why are Audio visual aids so important to teaching learning process? What points should be kept in mind while exhibiting an AV aid?


Audio Visual Materials is an techniques and which involves the sense of vision as well a s hearing. It is usually used in presentation prepared by the businessman to show graphs on the study of the company, college/university students to their reports and especially the teacher who use audio visual materials to clearly explain the lesson to the students.


Audio Visual Aids:

Audio visual aids are any device which can be used to make the learning experience more concrete, more realistic and more dynamic.

Audio visual aid is the combination of two media:

  • Auditory aids: Any instructional device that can be heard but not seen. E.g. Tape record, Microphones, Ear phones etc..
  • Visual aids: Any instructional device that can be seen, but not heard. Slide, film strips etc..

Purpose of Audio Visual Aids:

  • Best motivation.
  • Clear image.
  • Save energy and time.
  • Antidote of the disease of verbal instructions.
  • Capture attention.
  • reinforcement to learner.
  • Positive transfer of learning.
  • Gain & hold student interest.
  • Increase understanding and retention.
  • Stimulate the development of understanding and attitudes.

Functions of Audio visual aides:

  • They supply a concrete basis for conceptual thinking and hence, reduce meaningless word response of students.
  • They have high degree of interest for students.
  • They make learning more permanent.
  • They offer a reality of experience which stimulate self activity on the part of pupil.
  • Develop continuity of though; this is especially true of motion pictures.
  • They provide experience not easily obtained through other materials and contribute to the efficiency, depth and variety of learning.

Use of Audio Visual materials in education:

  • Students will gain knowledge of the latest in evolving theoretical and practical application in the communication field utilizing various resources and methods of inquiry.
  • Students will grow intellectually in their oral and written communication and critical thinking skills.
  • Student will become aware of the ethical and spiritual implications of communication on a diverse and global level.
  • Student will be knowledgeable of the latest in technology, software applications, and visual communication skills with the ability to demonstrate the skills in using technology.



    1. Q.5      Define validity of a lest. Further discuss the characteristics of a good test.

To be useful in determining a student’s current knowledge levels and predicting a student’s future success, educational assessment tools must have validity. Understand the concept of validity as it relates to assessments and learn about the three types of validity: content, construct, and predictive. Explore the internal and external factors associated with validity, review its relationship with reliability, and recognize the role of coefficients in measuring validity. Updated: 08/20/2021

Validity: Defined

The term validity has varied meanings depending on the context in which it is being used. Validity generally refers to how accurately a conclusion, measurement, or concept corresponds to what is being tested. For this lesson, we will focus on validity in assessments.

Validity is defined as the extent to which an assessment accurately measures what it is intended to measure. Let me explain this concept through a real-world example. If you weigh yourself on a scale, the scale should give you an accurate measurement of your weight. If the scale tells you you weigh 150 pounds and you actually weigh 135 pounds, then the scale is not valid.

The same can be said for assessments used in the classroom. If an assessment intends to measure achievement and ability in a particular subject area but then measures concepts that are completely unrelated, the assessment is not valid.

Factors That Impact Validity

Before discussing how validity is measured and differentiating between the different types of validity, it is important to understand how external and internal factors impact validity.

A student’s reading ability can have an impact on the validity of an assessment. For example, if a student has a hard time comprehending what a question is asking, a test will not be an accurate assessment of what the student truly knows about a subject. Educators should ensure that an assessment is at the correct reading level of the student.

Student self-efficacy can also impact validity of an assessment. If students have low self-efficacy, or beliefs about their abilities in the particular area they are being tested in, they will typically perform lower. Their own doubts hinder their ability to accurately demonstrate knowledge and comprehension.

Student test anxiety level is also a factor to be aware of. Students with high test anxiety will underperform due to emotional and physiological factors, such as upset stomach, sweating, and increased heart rate, which leads to a misrepresentation of student knowledge.

Measurement of Validity

Validity is measured using a coefficient. Typically, two scores from two assessments or measures are calculated to determine a number between 0 and 1. Higher coefficients indicate higher validity. Generally, assessments with a coefficient of .60 and above are considered acceptable or highly valid.

Types of Validity

There are three types of validity that we should consider: content, predictive, and construct validity. Content validity refers to the extent to which an assessment represents all facets of tasks within the domain being assessed. Content validity answers the question: Does the assessment cover a representative sample of the content that should be assessed?

For example, if you gave your students an end-of-the-year cumulative exam but the test only covered material presented in the last three weeks of class, the exam would have low content validity. The entire semester worth of material would not be represented on the exam.

Educators should strive for high content validity, especially for summative assessment purposes. Summative assessments are used to determine the knowledge students have gained during a specific time period.

Content validity is increased when assessments require students to make use of as much of their classroom learning as possible.

The next type of validity is predictive validity, which refers to the extent to which a score on an assessment predicts future performance.
