Tips for Using the Science Formative Item Pools The Formative Item Pool is an integral part of QualityCore®. Each course has its own pool of 225 multiple-choice items and 25 constructed response items, each aligned to QualityCore course objectives. The items are intended to help teachers measure student progress and determine whether a student or group of students needs additional instruction on particular skills or concepts. The items are presented as a PDF to maintain the visual consistency of graphics, special characters, and symbols. Each item is on its own page and is “bookmarked” for easy navigation through the PDF. This allows the teacher to easily find and arrange items into a formative assessment, homework, or classroom assignment, without having to reformat any text. The multiple-choice items are grouped by QualityCore Instructional Units. (See the QualityCore Instructional Unit Plans or the Course Outline to see how various objectives are covered in each of the units.) Each set of items is introduced by a cover sheet displaying the item Identification Number (ID), the correct answer (Key), the cognitive level, and the alphanumeric code for each course objective covered by that item. For Chemistry a Reference Sheet of Formulas and Constants similar to the one students use on the QualityCore End-of-Course Assessment, and the Periodic Table are provided. For Physics, a Reference Sheet identical to the one students use on the QualityCore End-of- Course Assessment is provided. Each constructed-response item has a coversheet describing the item, the cognitive level, the alphanumeric code for the course objective(s) covered by the item, and the cognitive task type. The items are matched to the relevant unit in the QualityCore Course Outline. The scoring criteria and a scoring rubric follow each constructed-response item in the pool. Three items are designed to emulate the items on the End-of-Course constructed- response assessment. Taken together, these three items provide students with a practice End-of-Course Assessment. © 2008 by ACT, Inc. Permission granted to reproduce this page for QualityCore® educational purposes only. QualityCore™ Formative Item Pool Biology I – Unit 1 The following pages contain items that can be used for formative assessments. The items provided in this document are intended to aid the teacher in measuring student progress. The items correspond to specific objectives for this unit. Each page has one item and the Identification (ID) number for that item. Each item is on a separate page to allow the teacher to easily choose independent items for a formative assessment. The following table gives the ID number for each item, the correct answer (Key), the cognitive level, and the alphanumeric code for each objective measured by the item. The objective referenced by each code is found in the set of course objectives. The items are listed in order first by Objective and second by Cognitive Level, but may be presented to the students in any order. The items are in the PDF in the order presented in this table.

The students selected 4 different types of plants and planted 10 seeds of each type: 5 treated with fertilizer and 5 not treated with fertilizer. All other conditions were identical. The students recorded the collected data in this table. Which type of plant exhibited the greatest increase in height when treated with fertilizer? A. Castor bean B. Okra C. Radish D.
