IU 4 Instructional Strategy Introduction: IU 4 is a continuation of the Develop phase. In this phase, activities are created to help the student achieve the instructional goal. These activities are listed as beginning, middle, and end activities. After developing the activities, media and method of delivery are selected. Rough draft materials will also be included in IU4. Instructional Goal: Upon completion of the Instructional Unit, Forensic Science students will be able to correctly match unknown fingerprints from a mock crime scene to a suspects known fingerprints by 1) classifying fingerprint patterns, 2) sub-classifying fingerprint patterns and 3) locating, identifying, and matching fingerprint ridge characteristics (minutiae). Event Beginning Activities Instructional Strategy Gain Attention To engage students a picture of a crime scene will be shown. Objectives Questions: What type of evidence could a suspect leave behind unknowingly? How could the police match a suspect to a victim, crime scene, or other evidence? The purpose of this IU is to train students in the comparison and identification of fingerprints from a mock crime scene. Fingerprints are the most common type of evidence found at crime scenes. The performance objectives are: 1. Given fingerprint exemplars (12-15 fingerprints) (CN), students will classify prints as Loops, Arches, or Whorls (B) with 100% accuracy (CR). 2. Using fingerprint exemplars from previous step (CN), students will identify respective sub-classes (B) with 100% accuracy (CR). Teacher or Student Student: Students will look at a photo of the crime scene. Questions will be underneath the photo. Time: 2 minutes Students: Students will read the lesson objectives that they must complete in order to correctly solve the mock crime scene scenario. Time: 1 minute 3. Shown a variety of fingerprint exemplars (5 fingerprints) (CN), students will locate and identify 8 -12 minutiae on each fingerprint exemplar (B) with 100% accuracy (CR). Prerequisites 4. Given a mock crime scene with fingerprint evidence (CN), students will evaluate evidence and determine the correct suspect (B) with 100% accuracy (CR). The pre-requisite skills for this lesson are: 1. Students will recall vocabulary from previous chapters. 2. Students will understand differences between class evidence and individual evidence. 3. Students will take a pre-test covering forensic science vocabulary. Student (1): Will be asked to recall prior vocabulary related to Fingerprint Identification such as evidence, crime scene, class characteristics, and individual characteristics. Student(2): Student will take a pre-test on forensic science vocabulary. Time: 3 minutes Present the Content A PowerPoint presentation will be used to: 1. Define fingerprint. Student: View the PowerPoint. 2. List the 3 main classes and the Time: 10 minutes 8 subclasses of fingerprints. Middle Activities 3. Define minutiae and visually depict the types of minutiae used in Fingerprint identification. Guided The following activities will be Student (1): Practice completed by the students with assistance of the teacher: 1. Students will identify fingerprint class and subclass on exemplar fingerprints shown on screen. 2. Students will locate and identify fingerprint minutiae on sample fingerprint shown on screen. Student will view a self-assessment PowerPoint that shows various fingerprint patterns. Student (2): Student will label a sample fingerprint with correct minutiae. Time: 5 minutes Independent Practice Feedback Completion of an assignment that covers all concepts presented in this instructional unit. Give the students an opportunity to clarify any issues regarding fingerprint classes, subclasses and minutiae. Review the assignment and re-teach any areas that need attention. Student: Complete the assignment to show understanding of performance objectives. Time: 10 minutes Teacher: Answer questions students may have and use examples to better explain for understanding. Student: Ask questions to better understand concepts. Assessment A mock crime scene will be give to students to assess mastery of performance objectives. Time: 2 minutes Student: Read the crime scene details and assess the fingerprint evidence. Use knowledge of fingerprint classes, sub classes, and minutiae to correctly match the unknown fingerprint sample to one of the suspects. Closure Ending Activities Teacher will close by summarizing the main concepts covered: Fingerprint classes and subclasses and minutiae. Time: 10 minutes Student: Turn in exit ticket with one thing you learned today. Time: 2 minutes Media Selection and Delivery System This instructional unit is an E-Learning module. The students will be able to login, read content materials, complete activities, and take assessments without a direct teach from the instructor. The students will be able to access all instructional unit materials through the computers in the science computer lab or on mobile devices. Desktop computer with high-speed Internet connection – The computer will be used by the student to download and view course content, answer discussion questions, complete activities, and assess learned skills. It will be used throughout the entire instructional unit. Blackboard Course Site – This is the delivery system for the instructional unit. This learning management system will allow the instructor to develop and host the instructional unit for students. It is accessible to traditional computers and mobile devices. Students must create a free user account and be enrolled in the course to access all course materials. This will be used through out the instructional unit. PowerPoint – Course topics will be presented using PowerPoint. Students will download and view the key topics covered in the presentation. The student will use it during the presentation of the content and for a self-assessment covering fingerprint patterns. Electronic Handouts – Electronic handouts in the form of fillable PDFs will be used by students in the independent practice section. The students will download these handouts, complete them, and submit them to the instructor for grading. First Draft Materials 1. Gain Attention: (1) http://www.imagesource.com/stock-image/Crime-Scene-IDI21NQ.html Questions: What type of evidence could a suspect leave behind unknowingly? How could the police match a suspect to a victim, crime scene, or other evidence? 2. Goal and Objectives: This instructional unit will help teach forensic science students the basic concepts of fingerprint patterns and ridge details (minutiae). Instructional Goal: Upon completion of the Instructional Unit, Forensic Science students will be able to correctly match unknown fingerprints from a mock crime scene to a suspects known fingerprints by 1) classifying fingerprint patterns, 2) sub-classifying fingerprint patterns and 3) locating, identifying, and matching fingerprint ridge characteristics (minutiae). 3. Prerequisites: The prerequisite skills for this instructional unit are prior forensic science vocabulary. Students will take a pretest that will assess their understanding of prior vocabulary such as: Evidence, Crime Scene, Class characteristics, Individual Characteristics. 4. Content: Students will download and view a PowerPoint presentation that covers key topics such as 3 main fingerprint patterns, sub-classes of the main patterns, and minutiae. 5. Guided Practice: Students will view a PowerPoint that will show various fingerprints. The students will attempt to correctly identify the type and sub-class of each fingerprint shown. 6. Independent Practice: Students will be shown Electronic Handouts (PDFs) with various Fingerprint patterns. Students will attempt to correctly identify all fingerprint patterns on the handouts. Students will be shown a handout with an enlarged fingerprint. Students will attempt to identify minutiae that have been highlighted. 7. Feedback: Students will have an opportunity to post questions to the instructor or fellow students to help clear up any misconceptions via blackboard course site class page. 8. Assessment: Students will download a mock crime scene scenario. The students must read all pertinent information regarding the crime scene, evidence, and suspects. Students must utilized skill learned in prior activities to correctly identify the perpetrator. 9. Closure: On Blackboard, students will submit an exit ticket to the instructor with 1 thing they already knew about fingerprints, 1 thing they learned from the lesson, and 1 thing about fingerprints they would like more information about.
