Construct cast metal alloy removeable partial denture framework

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x

4.3 Melt alloy and cast using appropriate materials, equipment and technique

5. Devest, trim, finish and evaluate metallic structures for removable partial denture

5.1 Select and apply cooling cycle

5.2 Remove the cast alloy structure from the investment without damaging the integrity of the structure

5.3 Remove oxides using an appropriate abrasive or chemical treatment

5.4Visually examine the cast alloy structure, correctly identify any casting faults and assess the viability of the casting

5.5 Remove sprues and trim and shape the alloy structure

5.6 Treat the surface of the alloy using appropriate materials and equipment and finish using appropriate abrasives and polishes

5.7 Position the cast on the master model and check accuracy of major connection and clasps and adjust any metal occlusal contacts with antagonist

5.8 Decontaminate the denture framework according to infection control guidelines

5.9 Dry the denture framework, replace on model and place in a sealed container for dispatch
