Validity and Reliability

          This week in our virtual class we started out with a game on Kahoot!  I had never seen this site before or used it but I really enjoyed it and believe that my future students would enjoy using it too.  I believe this would be a fun way to review material with students before an assessment.  We have learned that there are two types of assessments there are formative and summative assessments. This week we discussed that there are also two types of summative assessments.  The two types of summative exams are objective and subjective.  The objective assessment questions are the multiple choice questions, matching, true and false, and short answer.  The objective questions are either right or wrong.  The subjective questions are the essay questions or projects.  The subjective questions are not a right or wrong answer.  The student is able to explain their reasoning for their answers.  I remember when I was in school I feel like I learned more and remembered concepts longer when I was able to write essays or do projects on certain concepts.  I feel like I was able to accomplish this because I was able to spend more time with the concept and really research every aspect of it.
          In class we also discussed the fact that assessments need to be valid and reliable.  For an assessment to be valid it must measure what the teacher wants it to measure.  For instance it should measure what the teacher has taught.  This does not mean the teacher should  teach the test word for word.  The teacher should decide what objectives and standards they want the students to know.  Then, the teacher should develop an assessment, then a lesson, and then teach the students the information they need to know in order for them to be successful on their assessment.  Assessments are reliable if they are consistent.  For example, if the test is given to students this week and then the next week the scores should be the same or similar.  When I was in school I had many teachers who would teach us the test word for word and would give us a study guide the night before, where the assessment contained the same questions found on the study guide.  I also remember taking assessments where none of the students in the class knew the answers because the specific material was not discussed in class.  Those examples are how I related to the validity aspect.  The next example is how I was able to relate to the reliability aspect.  In school when the information was given to me in a study guide form, I remembered it just long enough to pass the test.  Although, when that particular information would appear on the end of grade exam I could not recall the information. On the other hand when the teacher would really teach the material and have us remember it in different ways, I would be able to recall the information on the assessments and the EOG's.  When a teacher is making sure the assessment is valid and reliable they are following some particular North Carolina Professional Teaching Standards.  I found two that I could relate this concept with under the standard four which is Teachers Plan Instruction.  The first one states that "Teachers use a variety of methods to assess what each student has learned," this includes their assessment processes.  The other one states that "Teachers plan instruction appropriate for their students."  The third standard I found is under standard five which is Teachers reflect on their Practice.  This standard states, "Teachers analyze student learning."  The assessments are analyzed to see student learning and progress.
           I found a resource that helps give teachers some helpful ways to make sure their assessments are reliable.  This article mentioned the act of giving longer assessments, giving more test, and giving clear directions.  If you would like to check out some of these helpful tips the article is linked below.
           I have learned for my future classroom, I want to make sure my assessments are valid and reliable for my students.  I will do this by teaching the information the students need to know that go along with the standards.  I will teach this information only after I have determined the standards and objectives, created an assessment, and created a lesson plan that coincides.  I will also make sure the assessments are reliable by giving the students clear directions, an assessment that has enough questions, and giving the students enough time to really learn and feel confident with the material.  I will also make sure the assessments contain objective and subjective questions.  I also believe in encouraging students to get a good nights sleep and to eat a good meal before any assessment and to take their time on the test.  I found the information this week to be very informative and helpful to understanding the assessment process and creation.  When an assessment follows these guidelines, I believe the students will have the skills and knowledge to be successful on all their assessments.
