Weld plastic using extrusion techniques

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

Elements and Performance Criteria




Performance criteria describe the required performance needed to demonstrate achievement of the element. Assessment of performance is to be consistent with the evidence guide.

1. Identify materials as being compatible for welding.

1.1 Identify materials as PE, PP, ABS, HIPS and PVC from specifications and worksite instructions.

1.2 Identify plastic materials and components supplied as being compatible for welding from specifications and tests.

2. Identify appropriate plastics welding conditions.

2.1 Identify welding machine type and operating requirements.

2.2 Identify plastic component materials and dimensions.

2.3 Identify and select appropriate welding rods or granules.

2.4 Select welding conditions for individual welding machines and plastic components.

2.5 Prepare field operational sheets as per enterprise specification.

3. Maintain, and calibrate welding equipment.

3.1 Set up welding equipment and work area as per enterprise specification.

3.2 Ensure safety equipment available and operational as per enterprise procedures.

3.3 Identify non-conformance, report and rectify according to enterprise procedures.
