Creating a decison-making matrix!

So the first thing I needed to do was be clear on the criteria for success. This would greatly enhance my ability to guide marking decisions for the summative assessment piece. What criteria was I going to use?
From earlier planning I had said that:

• ·         The design must be a container that holds the egg
• ·         The design must be original and use a minimum of 4 types of materials
• ·         The egg must not be cracked or broken when dropped
• The design is secure and will not come apart

After more reading and looking the the resources available in Week three, I think I have to change/add to this to include some specifications about material use, quality of design and justifications of design and modifications after conferencing about a prototype. I think perhaps, that the design specifications might stay the same, but I have added much more detail in the assessment criteria and thus, the teaching sequence.

            Students must prepare working communication of design

            Students will create 2 designs and use a decision making matrix to find the most effective design solution

            Students will teacher conference and have small group conferences about chosen design and student will justify               their design choices

            Students will form a production plan with specific attention to materials and their uses, tools and equipment
                         
            Students will be able to test/trial a design and document understanding and judgements about any modifications               that need to be made

            Students will be assessed on the skills in application of materials and the process of visualising a                                           design, prototyping, testing, conferencing, explaining, modifying and justifying a design.

            Students will evaluate their final product and experiment results.
