• Using hand tools and following directions - Projects

  I begin the lesson with students split into groups of 2-4. Each group has a Briggs and Stratton OHV engine. If several OHV small engines are not available, the instructor will have to use whatever automotive components they have available. Other items that work well for this lesson are carburetors, starters, and alternators.

  For the small engines, students are also given a tool set which has either a 3/8 or 1/4 drive socket set, various slotted and phillips screwdrivers, combination wrench sets, pliers, side cutters and other miscellaneous hand tools necessary for the lesson.  Students are given a step-by-step handout that will walk them through the removal and re-installation of the engines cylinder head.
• Students model what they learned - Group Work

  Each group of students now picks one member of the group to be in charge of the tools. Each group has its own tool person. When a tool is needed they must ask for it using the correct name. When the task is completed they turn it back into the groups tool person. (This also helps to start getting the students used to keeping track of tools throughout a repair).
• Students follow along with instructor - Demo / Modeling

  Once the students have picked their tool person, and have their tools, engines and worksheets, the instructor begins a thorough step-by-step with the students on the removal of the cylinder head. One of the benefits of the Briggs and Stratton OHV engine is that the instructor can compare  and contrast the components on the small engines with those on an automobile.

  The instructor should take the time to discuss each tool, properly identifying it as well as explaining the proper usage and common misuse and danger. The instructor should take the time to discuss each component as they are removed, in particular how they should be inspected on a vehicle and what determines the need for repair or replacement of each component.
• Students follow along with the reassembly - Demo / Modeling

  The instructor now walks the students through the proper reinstallation of the cylinder head on the engine. The students should have already inspected the components. Students are still required to check tools in and out with their tool person. It is the tool person's responsibility to make sure that the tools are properly identified.

  Remember: get the students used to returning tools to the tool trays or carts or however you store them. This will begin to get the students out of the habit of leaving sockets, wrenches etc. on radiator supports, fenderwells or the ground as they are working on vehicles in the shop.
• Students model what they have learned - Demo / Modeling

  Now is the chance for the students to complete the repair without the direct instruction of the teacher. The group will have to perform all of the previous removal/inspection/re-installation of the engines while discussing with each other each aspect of the task. The instructor should walk around and guide each group asking questions of individuals to check for understanding.
