Introduction
Introduction (LSI Quadrant I):
Use appropriate closure procedure as dictated by instructor’s district policy. Remind
students this information covers the basics of what they have learned in the first
semester of Welding I.
Outline
Outline (LSI Quadrant II):
Instructor Notes:
Prepare for semester exam by doing review and
showing PowerPoint. Students should engage with the
PowerPoint to pick up finer points of the discussion.
Be certain to review basic
safety procedures with
students.
Send students to the shop for a build experience using
the techniques discussed in the review.
All information should support topics included on the
semester exam.
Have students note those items in which they need
further Work or study. Give them time to practice those
items.
Application
Guided Practice (LSI Quadrant III):
Hold up or point to various pieces of equipment in the shop to do an oral discussion and
review with the students prior to doing the build portion of the final.
Independent Practice (LSI Quadrant III):
Build item on handout according to the specifications on the diagram.

Show the PowerPoint (students can take notes if the instructor feels it will help them).
Use individual slides during the presentation to call on individual students for answers.
Evaluation
Informal Assessment (LSI Quadrant III):
Answer any questions students may have as instructor feels comfortable during the
shop time. It is instructor preference as to how much help to give the students during
exam time.
Formal Assessment (LSI Quadrant III, IV):
Shop experience graded on rubric provided in addition to written exam grade.
