Unwrapping the Standards/Benchmarks

Understanding the EOC test item specifications

Ensure that teachers have a thorough understanding of standards and benchmarks as well as an understanding of how students will be assessed on summative assessments

Ensure that the lessons align to the complexity of the benchmarks, paying special attention to what the students will be expected to do on summative assessments

Ensure that all benchmarks are adequately addressed within the current scope and sequence and/or district/school pacing guide. Augment pacing guide to include any absent benchmarks.

ADDITIONAL INFORMATION

Webb’s DOK is a descriptive hierarchy that focuses on complexity, one aspect of rigor.

Each of the four Webb’s DOK levels describe the progression of rigor that is being taught and learned.

DOK 1 Recall and Reproduction DOK 2 Skills and Concepts/Basic Reasoning DOK 3 Strategic Thinking/Complex Reasoning DOK 4 Extended Thinking/Reasoning

Florida used Webb’s DOK/Cognitive Complexity Levels to align the cognitive demands of SSS to FCAT test items.

Low Complexity – Recall and recognition

Moderate Complexity – Flexible thinking and choice

High Complexity – Abstract reasoning and planning

DOK Level 1

Science low-complexity test items rely heavily on the recall and recognition or previously learned concepts and principles. Test items typically specify what the student is to do, which often is to carry out some procedure that can be performed mechanically. It is not left to the student to come up with an original method or solution.

Which of the following organisms is a consumer in this food web?

Moderate Complexity DOK Level 2

Science moderate-complexity test items involve more flexible thinking than low-complexity test items do. They require a response that goes beyond the habitual, is not specified, and ordinarily involves more than a single step or thought process. The student is expected to decide what to do—using informal methods of reasoning and problem-solving strategies—and to bring together skill and knowledge from various domains.

DOK Level 3

Science high-complexity test items make heavy demands on student thinking. Students must engage in abstract reasoning, planning, analysis, judgment, and creative thought. The test items require the student to think in an abstract and sophisticated way, often involving multiple steps.

SummativeWhat are my students expected to know,

understand, and do on national, state, and district common assessments?◦ SAT, ACT, Advanced Placement Exams, etc ◦ FCAT, End-of-Course Exams, etc.◦ Quarter Benchmarks, Semester Exams, etc.

FormativeWhat are my students expected to know,

understand, and do on school common assessments and teacher created or selected assessments?◦ Topic Quizzes, Unit Tests, etc.◦ quizzes, tests, presentations, projects, participation, etc.

• Each test item should be written to measure primarily one benchmark.

• Some benchmarks are combined for assessment, and the individual specification indicates which benchmarks are combined.

• Test items should be appropriate for students in terms of course content experience and difficulty, cognitive development, and reading level. The reading level of the test items should be Grade 9, except for science terms or concepts specifically addressed in the benchmarks.

• Test items should be written to the cognitive level of the benchmark unless otherwise noted in the individual specifications sections.

• Test items should assess the application of the concept rather than the memorization of science fact, law, or theory unless otherwise noted in the Individual Benchmark Specifications.

•Test items will not require the student to define terms.

•Test items that include a collection of data should require the student to analyze or interpret that data

•Test items will not require the creation of a chart, graph, or table.

•Biology 1 EOC Assessment items should not require use of a calculator.

•Test items may require the student to apply knowledge of the science concepts described in the prior knowledge benchmarks from lower grades; however, that knowledge should NOT be assessed in isolation.

•Test items will not require the memorization of equations or formulas unless otherwise noted in the Individual Benchmark Specifications. A reference sheet is not provided to students.

•Test items will not require memorization of the Periodic Table. A periodic table is provided to the students and is also found in Appendix D.

The context in which a test item is presented is called the item context or scenario. Test items should be placed in a context. 1.The item context should be designed to interest Biology 1 students. Scenarios should be appropriate for students in terms of Biology 1 content experience and difficulty, cognitive development, and reading level. 2.The context should be directly related to the question asked. The context should lead the student cognitively to the question. Every effort should be made to keep test items as concise as possible without losing cognitive flow or missing the overall idea or concept. 3.Biology 1 EOC Assessment scenarios are limited to those familiar to a Biology 1 student rather than global situations. 4.Item contexts should not refer to students using textbooks or the Internet as resources. Item contexts should focus on the students engaging in science learning rather than reading about science. Item contexts should avoid using a simple classroom scenario. 5.Item contexts and illustrations depicting individuals conducting laboratory investigations should include proper safety equipment and model safe laboratory procedures. 6.Scenarios describing scientific investigations should model current science methodology and adhere to the Intel International Science and Engineering Fair Rules and Guidelines unless otherwise noted in the benchmark clarification statements. 7.The item content should be timely but not likely to become dated.
