Evaluation is an important component of the teaching-learning process. It helps teachers and learners to improve teaching and learning. Evaluation is a continuous process not a periodic exercise. It helps in forming the values of judgment, educational status and achievements of students. It is desirable that mathematics teachers most acquire knowledge and understanding about various aspects of evaluation and its application in classroom.

3.1 Concept of Test, Examination, Measurement and Evaluation
Very often the terms Test, Examination, Measurement and Evaluations are assumed to be same and are used as through they are synonymous and mutually interchangeable. But they carry different functional meaning.
i. Test:
- A test usually presents a uniform ste of tasks to all members of the given group at a scheduled time with due prior notice.
- Sometimes unannounced tests are possible and useful in classroom.
- A test consists of a standard set of questions to be answered.
- A test is a systematic procedure for complaining comparing the behavior of two or more persons.
ii. Examination:
- Examinations are combinations of tests.
- Its scope is wider than the test.
- It may be defined as the assessment of a person’s performance.
- One is able to utilize the quality and effectiveness of the skills.
- The examination is intended only to focus on the tangible and easily measurable objectives of education like knowledge, understanding, skill and very little in the application.
- Examination is a procedure for measuring ability, achievement, interest etc.
- The test is an examination to reveal the relative standing of an individual in the group with respect to intelligence or personality or aptitude or achievement.
iii. Measurement:
- Measurement quantifies the data obtained through tests.
- It is simply a number or quantitative value which express the amount of characteristics possessed by an individual.
- This quantitative data is to be properly interpreted through evolution.
- Measurement is the process of assigning symbols to dimensions of phenomenal in order to characterize the status of phenomenon as precisely as possible.
- Test/Examination –> Measurement –> Evolution.
iv. Evaluation:
- Evaluation refers to both quantitative and qualitative aspects.
- It helps not only to measure educational achievement but also to improve it.
- It has a great influence on popular study habits and the Teacher’s methods of instruction.
- Evaluation is relative renew technical term introduced to design designate more comprehensive concept of measurement in fluid in conventional test and examination.
- Evaluation means a subjective judgement of the measurement.
Example: When Rani has secured 79 marks in a mathematics test, 79 is said to be a measurement of the test.
If we analyze in which objective she is good for test items are not do well is said to evaluation.
An evaluation provides a detailed analysis of the test.

Diffrentiate between examination and evaluation
Moreover these two are used inter rechargeable but in spite of the fact that both are the same thing or things that differ is no many ways evaluation is relative in Utah in the field of education it has more extensive scope and is definitely more valid objective and purpose cool then examination the relative difference can be summarised as under.
Examinations:
it refers to a system why are students are tested at the end of a definite period of instruction it limits itself to the testing of knowledge and skills of subject matter it is periodic process of assessment it measures only academic aspects of the child’s personality depends upon the date of achievement test.
Evolutions:
the changes brought in the behaviour of the students through education are continuous evaluation helps in the continuous appraisal of substances do evolution it is possible to test the overall changes brought in the behaviour and personality of the children it is a continuous process of assessment it measures academic and non academic aspects of child’s personality many tools of measurements like personality test interview objective test projective technique it is used.
3.2 Evaluation Meaning
Evolution in general is an act or a process that allows one to make a judgement about the desirability or value of a measure it is integrated with all task of education and its for post is to improve instruction and not Malli to measure its achievement some definitions are kholo evaluation is systematic continuous process of determining the extent to which specified educational objectives previously identified and define are 8 and the effectiveness of the learning experiences are provided in the classroom how will the goals of education have been accomplished the following are the important aspects of the definition evaluation implies a systematic process learning is more important than teaching it is a very comprehensive car it is continuous process objectives and learning experiences should direct the poles towards the accomplishment of educational goal it may be stated by showing interrelationship among objectives learning experiences and evaluation procedure definitions to measure means to observe or determine the magnitude of the ride evolution means assessment or africell encyclopaedia of educational research is an assessment of symbols to a phenomenon usually with reference to some social cultural and scientific standard Brazil and madrak the evolution process workability of learning experiences and change of behaviour of the students or objectives learning experiences and tense in our into Robin in the process of evolution evolution cannot be completed by neglecting any one of these…

Evolution procedure steps identifying the objectives visa to be validated to shutdown mathematical object is related to selected lesson for example to find out the formula for area of a sector the request knowledge of sector definition circle angle made by sector the people understand the relation between area of sector and area of circle the Google generalizing the formula they can solve the problems based on area of the sector defining the objectives in mathematics teacher teaching area of sector of the selected object it should be defined as are as follows the popular recall the formula xy 360 degree into Paya square the popular recognises the value of x the people sit is formula the fail substitute for the given values in the formula the popular establish relationship between area office sector and area of circle the Kapil journal-register formula the focal solve problems based on area of sector with accuracy and speed test selecting the teaching points on the objectives are set out the next step is to decide the content to help in achievement the objectives planning suitable learning activities teacher is completely to select two type of learning activities would like to provide to its feels so that the objectives maybe attend select suitable strategy to teach teacher mein select appropriate teaching uprose I analytical synthetic inductive educated or laboratory teaching construct the evolution devices tools in constructing evolution devices one should put in mind the actual objectives from form of questions level of importance of content easy to administrator etc it may oral written essay type or an objective type of test evolution admins administers the tool of evaluation selected or constructed to assess the selected objectives this will kill raw scores of the students interpret the scores which are obtained using various methods of interpretation use the results as feedback after testing who kills parents are the objectives are how far reject he will use the result in reconsidering the objectives and in every organising the learning activities this is known as feedback of the evolution.
3.3 Types of Evaluation
evolution is categorised into four types of types based on functions approaches and nature of preference formative evaluation summative evaluation diagnostic evaluation prognostic evaluation
Formative evaluation which is carried out to know the learning process during the instruction of teaching it helps both features and and Lana about their progress time to time it may be done orally or written in the class after completing the teaching class or at the end of a topic or unit or second chapter the teacher can you find the learning outcomes basing on which the which he can modify his methods techniques and device of teaching to provide better learning expenses it provides feedback to teacher sleep test unit test assignment seminar oral test quiz roleplay are come under formative evaluation this type of evaluation is based on teacher made test on the outcome of the init or crocin tort law of heart by the teacher himself.
Summative evaluation the term summative refers to assign a grade for students accident at the end of the term cause instructional program at the end of atom or course of instruction to known to what extent object is the Burj Khalifa have in accomplished and to what extend the instruction has been effective it has terminal nature quarterly half yearly annual are the examples of this type of evolution views evolution as a product it judges the efficiency of school programs or systems summative evaluation is employed for assigning great stupa kills as well as crediting certifying the level of achievement promoting to higher class selecting for different courses etc.
Diagnostic evaluationmanam of diagnostic evaluation is to identify the deficiencies and weakness of the people in particular concept unit branch etc so close during the course of instruction a teacher. Start in spite of adopting the standard corrective methods a purple faces recording learning facilities are that stills this type of evolution help to diagnose the difficulty.
Diagnostic test for students weakness difficulties in particular concept for chapter and helps to teach new teacher to the class at the time of admission of a student to school admission test is conducted whether the student have the actual knowledge about the complete class or not these are also an example for time stick test it can be made by employing observational techniques too.
Prognostic evolution prokinetic means forecast for product this type of evolution helps to forecast the probability of success in various area of particular subject assess the background skills and abilities which are prerequisite for success in a particular subject it may be used in beginning of acknowledge the aptitude and interest of the students in a particular field of their choice.
3.4 Tools of Evaluation
train is an instrument to write in this way different forms of tools are also required to measure and to evaluate the predetermined educational objectives they may be readily available or constructed by the teacher the ideas and principles underlying in the construction and administration of tools are treated as techniques tools and techniques are inseparable and both are accommodated in common words evolution device some common tools of evaluation are discussed here…
3.4.1 Types of Evaluation Tools
Basically into their testing devices non testing devices testing devices these are for the divided into moral written for practical test oral test this device is useful to test reading ability including pronunciation of Newton’s symbols formulae axioms and postulates etc these tests are supplement for the written exams on these are useful during the teaching after the teaching to test how far students are in the class and also in testing previous knowledge etc written test these test required the students who write the answers on the separate paper to the given questions so these are call the percentage this test may be either of the or of objective or of the both these types of test are useful in getting evidence on attainment of knowledge on ability to analyse a problem critically Oracle and organised a relative Lee large amount of material this may be standardized or teacher made test performance test used to evaluate different mathematical skills and focus of the students for example a teacher can affairs how will a student performs an experiment for handles geometrical instruments are over a medicine by the students goes does task on the particle is and sons all under this category non teaching devices records these are prepared by school for a student individually it includes informations about educational process attendance co-curricular activities and health it provides about students progress and to their teachers and parents on total records this type of maintenance the significance of the students their interest and provides guidance observation it may be defined as systematic methods of analysis and recording of behaviour of directly passing the individual or group there are certain trades like honesty punctuality persistence truthfulness etc one can be hardly measured objectively assessment of trades in the classroom in the playground in the school friends in the social functions etc can be observed.
Rating scale rating scales can be used to evaluate the various personality traits school courses school packages and various other programs it consists of some statements which can be created on 35 for 7 point scale for example to assess a particular we use a 5 point scale has very good good after delivery and poor the question is marked by the judges in any one of the five categories checklist the checklist is used for evaluating interest attitude and values of students it consists of a prepare list of items the presence or absence of an item may be indicated by yes or no against items interviews for obtaining information directly from an individual the oldest and the best known is that of the personal interview interview is is done in an Ariel atmosphere through a better personal report in interviews with students it is possible for teacher to secure evidence concerning the growth of interest changes in attitude etc.

3.5 Qualities of a Good Test
Reliability to the consistency of a measuring instrument it is his constitutes reliable it is consistent results in its successive administration test be trust third test it is accurate and consistent if test is conducted for different group of students for sem group by giving gap then the scores will differ very little or not all for their original values is said to be reliable example an achievement suppose an achievement test in method is is always start for the class IAS officer school in Hyderabad this code 97 test is always talk to them after a loss of time after 2 weeks for one month for the second or third time for score remains as resource the test is considered to be reliable the following are the methods of determining the reliability test retest method the split half method the method of rational equivalence the alternate or parallel for method.
Validity important characteristic of a good test it is said to be when it measures party intense to measure unless it is valid it’s ok no useful function the validity provides a direct check on how will the test fulfills is functions of a test refers to its truthfulness truthfulness does it refers to the very purpose of the test example a teacher wants to know whether the students have got success in a topic that is linear equation in one variable then teacher has to prepare a test in that only really measure of ability of solving linear equations in one variable the test is said to be valid objectivity it is most important factor that supports both the reliability and validity of a test test is objective when the scores of the test does not affect the original judgement in measuring instrument is said to be highly objective if the score are signed by different but equally important scores is not affected by the letters personal opinion or bias of the scores in another ways it is believed by different process or some other person at different timings in then there is little fairy in the scores that the test is said to be objective if test consist of multiple choice fill in blanks matching true false alternative response then the test is highly effective while easy type questions are highly subjective discriminating power a class can be divided into three categories based on their average and height measuring instrument should detect or measure small difference in the achievement of students and teachers discriminate between the good and the bad students should be classified the students then it is said to be a test has discriminating power comprehensiveness it should be as comprehensive as possible it should be competent and of to assess the knowledge skill interest and attitude as adequately as possible should include items measuring both the objectives and the content it should cover all the test items also for this a blueprint is needed practicability practicability is an important criterion for assessing the value of a test for this for both it should have the following characteristic in preparation 2 test not be too costly it’s so neither need too much time no labour in its preparation in for construction in administration it should be simple and easy in addition no opportunity for malpractice in scoring it should be provided to teacher simplicity as well as objectivity in scoring the responses of the students.

3.5.1 Types of Test
These are divided into Unit test, Diagnostic test, Achievement test.
Unit Test: Unit test is a short test to be given at the end of dating a name and it’s not a random assortment of questions it may be conducted for 15 or 20 or 25 marks instead of 100 marks it is understood by many teachers at present it is a teacher made test class room test.
Scholastic Achievement Test: This test measures the actual level of attainment achievement test assess the achievement of students regarding their learning about a particular fixed point in a test time it is drilling design to measure the instructional objectives this test are more comprehensive and their level of difficulty is also widely distributed the scholastic assessment can be categorised in teacher made and standardized test.
Different types of test items
Image
Essay Type Test:
The essay type test examination may be defined as a relative leaf return response to a problem situation or situations in which the written answer in mathematical test we use essay items to test analytical thinking logical ability communication skills drawing skills and reception in thinking in this items students are required to select organise and integrate information before writing about the answers.
Examples: If 60% people in a city like cricket 30% like football and the remaining life then what percent of the people like other games total number of people are 50 lakh find the exact number who like is type of game.
Merits:
- It is prepared easily.
- It test language ability of student.
- It develops good study habits.
- It eliminates guessing.
- Mathematical ability is like critical reasoning logical thinking analysis synthesis etc are to be tested.
- Systematic presentation can be developed.
- It can assess students ability to recognise and present his ideas.
- Students interpreting ideas are measured.
Limitations:
- It takes lot of time in testing.
- It has low validity law reliability and law usability.
- All objectives should not be tested.
- Scoring of some of these items objectively is so difficult because there are white Harrison’s in answers.
- It emphasis on rote memorization.
- There is a chance of grouping in this type examinations.
- It may have subjectively.
- There is no possibility to cover all the content.
Short Answer Type Tests:
Short answer questions generally required in short answer a question which can be answered in less than 4 steps may be called a short answer questions.
Merits:
- It improves the reliability and validity compared to easy questions preparation and administration easy content can be cover it takes less time it improves objectivity in scoring no provision for subjectivity all the objectives can be tested limitation there are significant limitation it has less chance to test language ability if test has all short answers Som of the ability belong to maths are left objective type test items or by taking or underlining on of the given choices this can only be one write objective answer to an objective question so this is test items are free from any subjective by other from the tester for the maker these test items are broadly divided into two categories Oracle type recognization types recall type test the test items are those in which the the the test items are those in which the answers are not given the examine has to provide the answer to the test item these are very short answer or one word answer and fill in the blanks for completion type very short answer one word answer that is given in question from form or statement then the exam in house to recall and write the answer it may be about it all formula symbol property etc example what is formula for volume of a cylinder in a triangle if one angle is 110 degree then what is the name of the triangle give an example for linear equation in one variable fill in the blanks composition type the test atom consists of a statement or sentence the blank has to be filled by the examine the item may contain one or two blanks it is better to avoid the sentence start with blank example sum of the internal angles is dash – dash in complex polygon if a b c are rational numbers then a + b equal to a b + AC is dash property if X + a is a factor of function then a power of minus A is equal to dash
Recognition types test items of answer the question the exam in notes to write on his or her own one has to select one stress among the given alternative so this test are also called fixed response test these are more objective general type test the main motors are discussed below the multiple choice type in this type or 5 possible answers question out of who is only one is correct exam in has to select only one as his response these items maybe in form of sentence statement fill in the blank or question other than the answer the remains alternators are cal destructors they may be complete with answer in selection as a response to the question example
Matching type test this type consists of two columns of items one column has questions and their answers each item of first column to be with the item in the second column answer column has two or three or more number of compare two questions in order to reduce gasing examples
True or false this time is question has two alternate is like or or yes or no the examine has to select any one from this as his response it is constructed easily example some sentence given mark with write in the sentence is true if the sentence false mark with a forex sign if in a triangle all sides are equal that is cal isosceles triangle to construct a rhombus two diagonal measurements are sufficient circle has four lines of symmetry.
Merits for Objective Type Questions:
- These are more reliable and valid.
- Contents should be covered.
- More instructional objectives have to be tested compared to essay questions.
- They are comparatively easy to construct.
- They are easily administered and scored.
- The items of the test ensure clarity.
- Very useful for competitive exams.
- It involves mental exercise.
- Higher learning outcomes like understanding application, analysis, judgement can be better tested through such questions.
- It reduces Rote memory.
- Little subjectivity is these type tests.
- These tests are very comprehensive being a very large number of items.
Limitations in Objective Type Tests:
- This type of test inadequately allows the opportunity for the people to organize and express his thoughts.
- There is a chance to examine to obtain correct answer by a random dressing.
- Test items are more in number compared to type so the cost of printing is increased.
- Preparing multiple choice is difficult why because locating a sufficient number of incorrect but good distracters is not an easy task.
- Guessing is encouraged.
- Higher learning outcomes like synthesis, interpretation, problem-solving skills, drawing skill etc. can not be tested.
- In True/False, a student who blindly answer all the items as true or false, a test may score 50% such tests have low reliability.
- These tests are unsuitable for diagnosing the weakness of the pupils.

3.7 Analysis and interpretation of Scores
After administering an achievement test it should be valid then we get scores by using this course statistical values like in measures of Central tendency measures of variability rank correlation calculated after that this statistical result compared to normal distribution curve characteristics and analysed analysis of test scores generally in normal class can be categorised into three types of cookies in a classroom they are below average average and above average in the class popular who scored around the approximate average score can be classified as other students those who secured below the average are below average students and above the average are up above average students analysis is done on the basis of marks scored with respect to objectives wise continent wise form of questions wise difficult level wise interpretation depending upon the results of the test the teacher can decide the level of class depending upon the type of the class teacher can make changes in his strategy of teaching used after 8 material and tries to bring the content to the student level in the classroom the teacher has to return back the answer scripts to the respective students after valuing the papers with the help of the open the teacher can make an analysis that how are the objectives are active at that concept they are good weather all form of questions are raised by the student or not etc after that teacher do the item wise analysis with variable available information the teacher can modified his teaching techniques select and use appropriate teaching learning material and take of remedial teaching.
