Using Test Results to Refine Teaching Nikki Yee August 25, 2011
Outline Interpreting Test Results Stanines, Standard Scores & Percentile Ranks Whats wrong with using grade-equivalents and age-equivalents? Test Results in Your Lesson Plan In the classroom In the Response to Intervention Model
How do we know if the kids are on track? Classroom observation Allows us to observe different aspects of student behaviour Compares a person to other students the observer has known Classroom (curriculum-based) assessment Gives us the first indication of difficulties Compares a person to his classmates Standardized testing Shows trends that may be problematic in the long run Compares a person to the developmental norm
How do test-makers know what is normal (typically developing)? A large sample of students (N=1,000 – 5,000) is taken based on varied gender, geographic, racial, and SES factors. The test is administered to the students and it is determined that (for example) at age 9.1 most students will score 7. This will be the score for a typically developing student. A Bell curve can be established based on this data in order to convert raw scores into standardized scores.
Bell Curve - Grades
What are some kinds of scores we can get from standardized tests? Stanines Scale of 1-10 Gives a general idea of how the student is doing Percentile Ranks 50% is the average Shows that a student is doing as well or better than 50% of his peers Standard Scores Scale of Age or Grade-Equivalents Shows what level the student is functioning at
What kinds of scores am I looking for? CAT – 4 Woodcock-Johnson III (Achievement or Cognitive) WISC 4 **Without a standard score, percentile rank, or at least a stanine, we cannot know if a student is experiencing a serious challenge. Stanines Standard Scores, Percentile Ranks
What are typically developing scores? Stanines: 3 – 7 Standard Scores: 85 – 115 Percentile Ranks: 16 – 84 Age or Grade Equivalent: ???
Whats wrong with age- or grade- equivalents? There is no defined typically developing range. These scores will naturally increase with age so they are not a good indication of improvement. An improvement of one grade level means something different depending on the grade. They tend to be demeaning & disrespectful to the student and people who care about the student. BUT they give us some indication as to where we can begin instruction.
How does this fit with RtI? Tier 1 All students start off in Tier 1 – those in the typically developing range will stay in Tier 1 (68.2%) If students are struggling in Tier 1, test results can refine teaching. Tier 2 Students who are a struggling should be in Tier 2 (27.2%) Testing should point the way for intervention in Tier 2, and show whether or not improvements are taking place. Tier 3 Students who have major difficulties should be in Tier 3 (4.4%) If students need to be placed in Tier 3, testing should indicate precise areas of intensive intervention. The Educational Psychologist should be called in to determine whether or not there is a more severe cognitive impairment.
What kind of assessment do we use for RtI? Qualitative tests (e.g., Qualitative Reading Inventory) can be used yearly to see if improvements are occurring. Standardized tests can only be repeated every 3 years, so the results should be used to hone in on areas of need.
How can we use test results in the classroom? How can we use strengths to build up weaknesses? Note that despite a poor academic performance the student may have strengths that he is NOT ABLE to show
Specific Strategies for Specific Struggles Math fluency Math word problems Reading comprehension Decoding Memory Monopoly, cribbage, blackjack, any board game with 2 dice Community outings Questions & inferences, visualization Grapho-syllabic intervention Memory games, add-a-word sentences, memorize passages, add kinesthetic cues
