Introduction
Introduction (LSI Quadrant I):

SAY: “We have explored various aspects of welding in class, but there are types
of welding that some of you may not have thought of”

ASK: “What do you think the benefits and risks would be of welding

underwater?" Discuss with students.
Outline
Outline (LSI Quadrant II):
Instructor Notes:
• Do Introduction.
• Show PowerPoint and discuss.
• Review material
• Assign students in groups to research and interview
someone who works in underwater welding.
• Students present what they have learned in class.
Students can present orally,
with handouts, or in any
other fashion, or invite the
person in as a guest
speaker.
Application
Students take notes during PowerPoint.
Independent Practice (LSI Quadrant III):
Students research independently.
Summary
Review (LSI Quadrants I and IV):
Group critiques each other’s presentations.
Evaluation
Informal Assessment (LSI Quadrant III):
Teacher monitors individual/group progress as students work on activities. Teacher
provides help/direction as needed.
Formal Assessment (LSI Quadrant III, IV):
Instructor will give a grade for participation and presentation (50%) each.

Extension/Enrichment (LSI Quadrant IV):
Knowledge of underwater welding will come in handy if the student is looking for a new
and different job in welding and is also interested in diving.
