What Are The Potential Problems That May Arise From Using The Assessment Evidence

4. Discuss potential problems with validity and reliability that can arise from using different assessment evidence. What dangers must a teacher guard against when grouping students, planning instruction, grading and forming initial perceptions of student’s characteristics? How might teachers know when they have valid and reliable information?
A potential problem that can arise with validity and reliability when determining assessment evidence is insufficient or incorrect information to make such a valid decision. It is vital the information is interpreted accurately. It’s the job of the teacher to question whether they are collecting the right information needed to formulate a correct assessment about the student. Another potential problem is the teacher tests the students on material that
they have not yet been fully taught, and expect a certain result that may not be possible.
Some assessment dangers that teachers must guard against when lesson planning, is whether the information being gathered is relevant and appropriate to achieve a valid and reliable assessment. Validity is a key characteristic, without it the decision can be harmful and have a negative effect on the student or class. To create a reliability in the teacher’s assessment it must stand the test of time. If the assessment information gathered could not be used in a different learning situation then will be deemed as unreliable. Another danger is if the assessment information does not produce stabile and consistent data, the teacher should be cautious in using it to make a decision about the class or student. The criteria’s the teacher should look for to get valid and reliable assessment information is that I am collecting the right information to be able to make the correct decision. The collection of several pieces of information about the behavior or performance being assessed. Teachers must be aware that some assessment information may be unreliable because factors such as interruptions during testing, student attention span, clarity of instructions
and luck of student guessing. It is important for the teachers to realize that “Valid assessment must be reliable, but reliable assessment need not be valid” Once a teacher has the confidence and knowledge to be able to assess the validity and reliability of a student, they will be able to correctly process correctly valid and reliable information.

5. Discuss the ethical aspects of teaching and being a teacher. Why do we have ethical standards in teaching (to protect students)? What are examples of unethical teacher behavior related to assessment?

As there teacher provide the best instructions available for all students. Standard ethical aspects of teaching refers to the teachers’ fairness in dealing with all students. Some ethical standards are: inform students about teacher expectations and assessments before beginning teaching. Teach students what they are being tested on. No snap judgments, avoid stereotyping, and identify emotional students and slow learners. Avoid references that students from different genders, race, religion and cultures might find offensive No bias toward students with limited English. Some examples of unethical teachers behavior related to assessment are, not informing students of teaching expectations and assessments. Show favoritism to individual students. Show bias or prejudice toward limited English speaking students or students with different race, religion, or cultural backgrounds. Not looking out for students with special needs. Teachers acquire a great deal of personal information on their students, it is unethical to share this information indiscriminately. There is ethical responsibility associated with the collection and use of student assessment information.
