Procedure
	The actions of students and teachers and the interactions among and between students and teachers:

(See Student Work #1 and Student Work #2 and the Time Required section of this Learning Experience for further details.)

The following is the sequence of events for completing the Learning Experience:

• Web page design and basic HTML (students set up individual web pages and do initial project research for historical references, design ideas, ergonomic and material strength data (sites are bookmarked for later use)
• Anthropometric data collection (measurements are taken of all students within their own team and recorded on handout)
• ·Teams formed, assigning jobs of Structural Engineer, Ergonomics Engineer, and Product Design Engineer ( See Chair Design Instruction)
• Statistical analysis ( mean, median, mode and range)
• Data is recorded by ergonomic engineers on class chart . Ergonomic engineers meet as a group and statistical calculations are performed. They decide which statistical measure is best suited for each of the 8 chair dimensions on the anthropometric handouts. Ergonomic charts are posted in the classroom which describe each measurement and decisions made.
• Structural elements and forces using a video and interactive lesson: columns, beams, trusses, dead, live, and dynamic loads, concentrated & uniformly distributed loads, compression, tension, shear, bending, rotational forces, and corrugated cardboard as a building material.
• Sructural designs are created and tested by structural engineers as a group (3 designs minimum). Load capacity data on single, double and triple ply cardboard will also be included in the design and testing, and all findings will be recorded in structural journals (sketches must be included).
• A lesson on drawing circles/arcs and angles in isometric is given by the instructor to the entire class (3 thumbnail sketches and one isometric sketch on isometric graph paper by product engineer)
• Structural work, anthropometric data analysis and design sketches will be created during the same class periods.
• Trigonometry & Dimensions instruction (Teacher will review anthropometric data with class and demonstrate how to calculate true material lengths given angle and dimensional constraints.) All dimensions are put on isometric sketch. Sketch will need to be xeroxed for other team member use.
• Study models are created from corrugated cardboard in order to incorporate design with structure (all team members participate in modelmaking)
• Drawings of the top, front, side views, by hand or on CADD (ergonomic engineers), as well as section drawings: and/or other structural views (structural engineers)
• Final isometric drawing: inked and rendered (product engineer)
• Model making techniques demo lesson: safety and the proper use of cutting knives, and tips for cutting, scoring, laminating and temporary taping of cardboard while preserving the classroom desks and worktables. (all members of team will work on final, full-scale chair model)
• Chairs are tested (teams meet for discussion, evaluations and testing)
• Electronic Portfolios are completed and presentations are made.
• Assessments are completed as a cooperative effort. (See Assessment Plan section of this Learning Experience.)
