Review electrical engineering plans to ensure adherence to design specifications and compliance with applicable electrical codes and standards. Compile and maintain records documenting engineering schematics, installed equipment, installation or operational problems, resources used, repairs, or corrective action performed. Review installation or quality assurance documentation. Review, develop, and prepare maintenance standards. Soft Skills: Realistic; Investigative; Conventional Teacher Preparation: Review the PowerPoint presentation, the quiz, and the definitions. You may want to focus your presentation on the PowerPoint and the quiz, but the major goal of this lesson is to have the students actually practice a design process. For this lesson we want students to go through the process of defining the problem, doing some background research on existing designs and solutions, then making some drawings of their design. They must practice the process before they apply these steps to a real robotic project, which will come a little later. Some ideas for a simple object to design are a gripper, a can crusher, an object sorter, a tennis ball kicker or shooter, or come up with your own idea. References: 1. The steps of the design process in the PowerPoint are based on those given in the educational video at teachersdomain.org http://www.teachersdomain.org/resource/phy03.sci.engin.design.desprocess/ 2.

Computer Learner Preparation: No learner preparation is required since this is a basic module and prepares students for a design project. The design project would use this module for learner preparation. Introduction Introduction (LSI Quadrant I): SAY: Today we are going to learn about the design process. The design process is important because no business or manufacturer wants to devote resources to a project until they can be assured that the idea is a real solution to a problem. ASK: How can you convince a manager that you have a good idea for a project? SHOW: Have some drawings like this (show drawings) that show the manager that you have thought about it, done some research, and have come up with something that might work. SAY: You cannot build something until you have a plan for it. ASK: Has anyone had any ideas for something you wished you could build? SHOW: This is what you need: a document, a plan, a drawing. Outline Outline (LSI Quadrant II): Instructors can use the PowerPoint presentation, slides, handouts, and note pages in conjunction with the following outline. MI Outline Notes to Instructor I. . Engineering Design Process PowerPoint presentation A. A process has steps, usually defined steps B. A series of actions, changes, or functions bringing about a result C. Overview and the purpose of design D. Comparison of Engineering Design to Scientific Method II. Watch the video referenced on slide 6 A. This video and the web site documentation form the basis for the presentation B. The presentation can be enhanced with personal knowledge or some example of alternate design processes (Slides 1-5) Begin PowerPoint presentation. Many of the central concepts are repeated over again. One of the main ideas is that students must have a plan of action before they can ever build something. Students need to take notes during this lesson. Distribute Design Process Definitions handout. (Slide 6) Use the links in the PPT presentation notes to add to the presentation.

Basic steps of the design process A. Give each step B. Later slides explain each step in more detail. (Slide 7) Make sure students write these steps down. IV. Each step explained in more detail A. Identify the challenge B. Research and brainstorm C. Design and solution D. Test ideas E. Evaluate F. Build (Slides 8-13) Add personal experience, or talk about how these steps might look different for different occupations V. Have students write out a plan A. The plan and the drawing are important to meet TEKS requirements (Slides 8-10) VI. Other considerations A. These are practical considerations B. Complicated designs either don’t work or break down C. What works best? (Slides 14-17) VII. The process is iterative! A. The grand finale B. Go from here into a practice design process C. The simplest design process example has a few sentences describing the problem and a possible solution, some details from topic research, and a drawing. (Slide 18) VIII. Students practice the design process (several times from simple, then to more detailed as needed) A. Define the problem B. Perform research of designs and solutions It is important that students practice the design process. They can start with some simple Copyright © Texas Education Agency, 2012. All rights reserved. 5 C. Start with a simple drawing D. Create detailed drawings with dimensions and specifications E. Will be able to apply steps to future robotic projects Note: Students should practice the design process at least twice, once with simple drawings (C); and again with more detailed drawings (D). More practice would be better. drawings, but then add research. Have several drawings ranging from simple to more detailed. Teacher provides examples of what the students should design. Distribute the rubric to evaluate the design process practice. The rubric is designed and worded for the full design project, and the simpler basic designs a student will do initially should be graded with leniency, or using a few simple criteria from the rubric. The rubric lets students know what is expected, but they should get a chance to start easy and build up to full expectations with practice. Verbal Linguistic Logical Mathematical Visual Spatial Musical Rhythmic Bodily Kinesthetic Intrapersonal Interpersonal Naturalist Existentialist Application Guided Practice (LSI Quadrant III): Show the students some samples of a simple drawing. Give the students some examples of what you want them to design. Independent Practice (LSI Quadrant III): Start with a simple drawing, perform independent research, and create more detailed drawings with dimensions and specifications. Summary Copyright © Texas Education Agency, 2012. All rights reserved. 6 Review (LSI Quadrants I and IV): Question: What are the steps to the design process? Answer: Identify the challenge; research and brainstorm; design a solution; test ideas; evaluate; build! Question: What is the most important step in the design process? Answer: The drawing (or drawings) that show the solution. Evaluation Informal Assessment (LSI Quadrant III): Attentiveness in class, note taking, questions, sample drawings. Option to use the design process rubric in a simplified form to assess preliminary drawings. Formal Assessment (LSI Quadrant III, IV): The Design Process Quiz, a formal evaluation of student design process practice using the rubric (first in a simplified form for simple sketch practice, then more completely as needed for more detailed drawings and student practice on the full design process). Extension Extension/Enrichment (LSI Quadrant IV): Have students do research and come up with designs for a more complicated project, using examples from robotic competition contest objectives.
