All MC items are worth one point each. Multiple-select (MS) questions with five to seven answer options and more than one correct answer. For MS items, the question identifies the number of correct answers, unless it is part of a Two-part Dependent (TPD). In a TPD, the question in Part B will then be worded to “select all that apply.” All MS items are worth one point each. • Technology Enhanced Items (TEI): uses technology to capture student comprehension in authentic ways. TE items are worth up to two points and may include item types such as, but not limited to, drag and drop, dropdown menus, and hot spots. • Two-part Items: require students to answer two related questions, worth a total of two points. Two-part items may combine MC, MS, and/or TE item types. o Two-part Dependent (TPD): the first part must be correct in order to earn credit for the second part. TPDs are scored as follows: . If both parts are correct, score is 2. If Part A is correct and Part B is incorrect or partially correct, score is 1. If Part A is incorrect, score is 0 regardless of Part B. o Two-part Independent (TPI): each part is scored independently, with each part worth one point. • Constructed Response (CR): requires a brief response provided by the student and will be scored using a 2-point rubric. These items may require a brief paragraph, a few sentences, and/or completion of a chart. • Extended Response (ER): asks students to write an in-depth response that expresses the students’ ability to apply all three dimensions of the LSS for Science and will be scored using a 9-point rubric. BIOLOGY PRACTICE TEST ANSWER KEY – AUGUST 2021 5 Biology Practice Test Answer Key Session 1 Item 2 (TEI) Develop a model that can be used to explain the stages of growth and development that result in a salmon fry. Drag each statement into the correct box to show the stages in order. BIOLOGY PRACTICE TEST ANSWER KEY – AUGUST 2021 6 Biology Practice Test Answer Key Scoring for Session 1 Item 2 (TEI) Scoring Notes: This item is worth 2 points. Partial credit (1 point) will be awarded if half or more of the student responses are correct. For this item, the key contains 4 correct responses; therefore 1 point will be awarded if the student selects 2 or more correct responses.
