(3) A NOTE FOR TEACHERS We hope you will find this Applied Practice booklet helpful as you work to prepare your students for the Advanced Placement Exam in Biology. As your students read and use the biology textbook, lab manual, and other resources covered in your curriculum, they will have the opportunity to practice and to develop skills that will be tested on the exam. We offer a few suggestions and explanations to help you receive the maximum benefit from our materials. 1. Applied Practice booklets do not purport to duplicate exactly an Advanced Placement Examination. However, questions are modeled on those typically encountered on these exams. Thus, students using these materials will become familiar and comfortable with the format, question types, and terminology of Advanced Placement Examinations. 2. Because the multiple-choice sections vary in length, in some cases being longer or shorter than those typical of the Advanced Placement Exams, the multiple-choice sections of this booklet are not ideally administered in a timed situation. A teacher may certainly review the section and set a time he or she considers reasonable in his or her classroom. However, these sections were not written with specific time limits in mind. 3. A few multiple-choice questions assume a student’s familiarity with laboratory procedures not normally done as part of the required AP Biology labs. While such familiarity would not be assumed on an Advanced Placement Exam, it is appropriate for materials designed for use in a classroom setting, particularly where science as a process is emphasized. Students should be familiar with the procedures and results of the twelve required AP Biology labs, and several of the booklets in the AP Biology series will contain multiple-choice questions based on the required labs. 4. The free-response questions do lend themselves to timing. As on an Advanced Placement Exam, students should be allotted approximately 20 minutes per essay. The Advanced Placement AP Biology Exam has four free-response questions, while this booklet presents five free-response questions, so you may want to use the questions individually and not as a group. 5. The teacher should adapt this material to meet the needs of his or her own students and to suit his or her instructional strategies. Each section can be given on its own, or larger sections can be administered at intervals throughout the unit. Consecutive numbering of questions throughout the multiple-choice section allows for the use of mechanically scanned answer sheets. 6. Students should be given guidance in their early practices until they become familiar with terminology, format, and question types. Later, students can work more independently.. ©2008 by Applied Practice, Ltd., Dallas, TX. All rights reserved.. 5.

(4) 7. These materials are not designed to be used as tests of whether or not a student has read the textbook or performed the AP Biology labs. The questions are rather designed to help train students in carefully reading and analyzing multiple-choice and free-response questions. 8. The teacher might want to scan the terms used in the answer choices to make sure students are familiar with these terms. The glossary contains many of the biologyspecific and science-specific terms that appear in the questions. Thank you for using Applied Practice materials in your classroom. We always welcome comments and suggestions..
