Here I am going to wrote about the testing and Evaluation. This blog is my academic task given by Dr Dilip barad sir from Department of English Bhavnagar University. Here my task is upon to write given question.
1) write on Validity and reliability the test
2) wrote on practicality of the test
3) who do you understand by backwash?
4) difference between assessments and Evaluation
5) How do you define good assessment?
So here I am given answer of this question so let's see
1} Validity and reliability of the Test
Validity
Validity refers to how accurately a method measures what it is intended to measure. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world.
Reliability
Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable.
Different between validity and reliability
Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.
It’s important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research.
2} Practicality of the test
It refers to the economy of time, effort and money in testing. In other words, a test should be easy to design, easy to administer, easy to mark, and easy to interpret the results (Bachman and Palmer, 1996). Moreover, according to Brown (2004) said that the test that is practical it needs to be within the means of financial limitations, appropriate time constraints, easy to administrator, score, and interpret.
3} What do you understand by backwash?
Backwash is the effect that knowledge of the contents of a test may have on the course which precedes it. It may be positive or negative.
The backwash effect has tersely been referred to as 'the influence of testing on teaching, and learning.' (Gates 1995) This study ventured to examine the backwash phenomenon from teachers' perspective taking learners as the inducing factors of the backwash effect. The Qualitative approach was espoused. The data was collected by conducting semi-structured interviews with the HSC English language teachers of the government colleges in Hyderabad with a 'convenient sampling'. The participants numbering ten in total were equally taken from both the genders. The interview responses were thematically analyzed and coded to form a compact but summarized picture of the backwash teachers. The findings provided the breaking-through insights into the flip side of the backwash from teachers' vantage point. It established that the apathy/lack of interest by students brings an intense kind of backwash on teachers' teaching method, and content, and their overall morale.
4} Difference between assessment and Evaluation
Assessment is the systematic process of documenting and using empirical data to measure knowledge, skills, attitudes and beliefs. By taking the assessment, teachers try to improve the student's path towards learning. This is a short definition of assessment.
Assessment is feedback from the student to the instructor about the student's learning. Evaluation uses methods and measures to judge student learning and understanding of the material for purposes of grading and reporting. Evaluation is feedback from the instructor to the student about the student's learning.
Evaluation focuses on grades and might reflect classroom components other than course content and mastery level. An evaluation can be used as a final review to gauge the quality of instruction. It’s product-oriented. This means that the main question is: “What’s been learned?” In short, evaluation is judgmental.
5} How do you define good assessment?
Assessment literacy involves understanding how assessments are made, what type of assessments answer what questions, and how the data from assessments can be used to help teachers, students, parents, and other stakeholders make decisions about teaching and learning. Assessment designers strive to create assessments that show a high degree of fidelity to the following five traits:
1. Content validity
2. Reliability
3. Fairness
4. Student engagement and motivation
5. Consequential relevance
