1. Reliability Comes by Default of Validity
LeBlanc (2009,) discusses an assessment may be reliable, but this does not mean it is valid, a valid assessment though does guarantee reliability. This concept is important to be mindful of when establishing the validity and reliability of an assessment and an action plan for student achievement. If enough reflection and review of the validity of an assessment/plan is taken into account, prior/post administration of the assessment/plan, then the level of reliability will be appropriate and sufficient. Educators need to have the flexibility and comprehension to ensure student achievement is occurring measuring up to a higher level of validity.
2. High Validity
LeBlanc (2009), also discussed the validity of high-stakes tests and their validity having a correlational coefficient of at least 0.8 (a high positive correlation). LeBlanc is implying a high level of validity must be established by these tests to ensure student achievement. Listed below are questions an educator must ask themselves and/or others concerning high validity for student achievement.
The questions a reflecting teacher should expect/review when determining high validity for an assessment:
1. Does this particular reading test meet the instructional objectives reflected on by the assessing teacher?
2. Does the reading content presented by the teacher reflect upon the content presented to the students?
3. Has the appropriate cognitive reading level been established by the assessing teacher and reflected upon?
4. What will be the proper scoring criteria (rubric, etc.) used for this reading test?
The questions a reflecting teacher should expect/review from their students' responses during and after the given assessment:
1. What observations will the teacher make during the assessment period?
2. (Reflection) After the assessment period, what observational changes need to be made during the assessment?
3. What questions should a teacher ask student(s) (interview) post-assessment time, for future consideration and reflection?
4. What are the potential consequences prior, during, and after the assessment, pluses and deltas?
3. Measurement of Error
Kizlik (2011), mentions we measure to obtain information about what is, and such information may or may not be useful, depending on the accuracy of the instruments we use, and our skill at using them. It is crucial to remember there is always a measurement in error regardless what is being measured (quantitative and/or qualitative gathered data). So even these established rules and standards we measure by, there maintains an error of measure. Educators need to remember, error is underestimated (McMilan 2000). To maximize a high level of student achievement we, as educators, must remember to minimize the measurement of error for our students through our assessments and action plans.
Teacher & Administrators Concepts:
1. Assessment is inherently a process of professional judgment.
Whether that judgment occurs in constructing test questions, scoring essays, creating rubrics, grading participation, combining scores, or interpreting standardized test scores, the essence of the process is making professional interpretations and decisions (McMilan 2000). We as educators, in our differing judgment(s), need to remember being objective is relative to the defining individual. Understanding this principle helps teachers and administrators realize the importance of their own judgments and those of others in evaluating the quality of assessment and the meaning of the results (McMilan 2000). The essence of wisdom is the action educators take to ensure a high quality of achievement for students and themselves professionally.
2. Assessment decision-making is influenced by a series of tensions.
Competing purposes, uses, and pressures result in tension for teachers and administrators as they make assessment-related decisions (McMilan 2000). Educators are consistently under pressure concerning critical assessment-related decisions. I assume, each school is different in their approach to the decisions made and the results discovered. We must remember, that we will try to accommodate all the tensions that exist, but in the end results to optimize our educational environments, trade-offs are inevitable (McMilan 2000).
3. Assessment influences student motivation and learning.
What is the nature of feedback, and when is it given to students (McMilan 2000)? According to LeBlanc (2009), student feedback should always be accomplished and presented immediately-to soon after the attempted assessment. How does assessment affect student effort (McMilan 2000)? In my observations, if the expectations were high initially prior to the student(s) attempting the assessment, then post-attempt, those students who felt they under achieved persevere (regardless of debate) as expected. Answers to such questions help teachers and administrators understand that assessment has powerful effects on motivation and learning (McMilan 2000). McMilan (2000), states for example, recent research summarized by Black & Wiliam (1998) shows that student self-assessment skills, learned and applied as part of formative assessment, enhances student achievement.
