KCTCS Course Title
This lesson will instruct the student on how to identify type of vehicle construction (space frame, unibody, body-over-frame), and recognize the different damage characteristics of space frame, unibody, and body-over-frame vehicles. Knowledge of these techniques and the skills required to correct problems associated with this task are necessary for a student to acquire if they wish to compete for high paying, high skilled jobs in a Collision Repair Facility. Entry level technicians need to be able to perform this task to 100% accuracy. Incorrectly performing this task can lead to an automobile accident or create customer satisfaction issues.
Identify type of vehicle construction (space frame, unibody, body-over-frame).
Recognize the different damage characteristics of space frame, unibody, and body-over-frame vehicles.
Given the proper tools and instruction, the student will be able to identify the type of vehicle construction (space frame, unibody, body-over-frame), recognize the different damage characteristics of space frame, unibody, and body-over-frame vehicles, and pass a written test covering the task with 100% accuracy.
Inform students that vehicle construction can be unibody, body-over-frame or space frame. Tell them that a unibody has no detachable frame. The vehicle is constructed of panels welded together. Most subcompact, compact, and intermediate-sized vehicles are unibody. Explain that a full-frame vehicle is constructed by bolting a body to a separate frame. Most pickup trucks, sport utility vehicles (SUVs), and some large passenger vehicles have a full frame. A space frame is similar to a unibody in that it is made of welded panels. However, tell them that in a space frame, outer body panels do not contribute to the strength of the unibody. Lumina-type vans and Saturn models are examples of space frames.
Instruct students that the unibody is designed to absorb the impact or crush during a crash. The energy of the collision is absorbed by convolutions in the structural members. Tell them the collision energy is gradually dissipated as it is transferred along the structural parts. In a body-over-frame vehicle, explain that the collision energy is not absorbed in the same manner as a unibody; the energy is transferred. Explain that a body-over-frame is stronger than a unibody, however. Inform them that a body-over-frame vehicle can have the following types of frame damage: diamond, twist, sag, mash, and sidesway, and a unibody vehicle may have these, types of damage: twist, sag, mash, and sidesway.
Objective 1. / Formative assessment / Instructor will observe students as they practice the procedure to assure correct procedure and safety practices are being followed. A checklist will be utilized to chart student progress on the task. Questioning techniques will be utilized as necessary to demonstrate student comprehension / Adaptations and/or accommodations for special needs students will be added if required.
STUDENT ASSESSMENT: (Assess student progress with performance criteria.)
Objective 1 / Summative assessment / written test questions on stated objective / adaptation and / or accommodations for special needs students will be added if required
IMPACT--Reflection/Analysis of Teaching and Learning: (How did students’ progress in relation to the state objectives? Was the instruction successful? Analyze samples of student work particularly that which is unsatisfactory, for the purpose of planning further instruction.)
REFINEMENT--Lesson Extension and Follow-up: (To be filled in as the lesson is modified during initial planning and/or during the teaching learning process.)
