Navigate using celestial aids

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

Books
Reference books for 'Navigate using celestial aids' on fishpond.com.au. This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to ntisthis.com for every purchase, so go nuts :)


Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

1. Establish cardinal points by day using the sun

1.1 Complete movement of the sun is recorded over a solar day using a sun compass constructed in an open and level area.

1.2 True north, associated cardinal points and the arc of the sun are annotated on the sun compass.

1.3 True north and associated cardinal points are notated using a quick shadow stickmethod and allowance is made for the deviation arising from early morning or late afternoon siting.

2. Establish cardinal points by night using celestial aids

2.1 Celestial bodies are identified in the sky and used to extrapolate the location of cardinal points directly.

2.2 Celestial bodies are identified in the sky and used to extrapolate the location of the celestial pole.

2.3 Celestial pole is used to extrapolate true south (or north) on the earth/sky horizon and a compass showing all cardinal points is established on the ground.

3. Employ improvised direction measuring techniques

3.1 An analysis is conducted, based upon the survival situation, and an appropriate direction of travel (if any) is selected to optimise survival or rescue.

3.2 An improvised protractor is made using a multifolded sheet of paper and the desired angle of direction is annotated.

3.3 Protractor is aligned with the established cardinal points of the compass, and the annotated angle is used to select a coincident recognisable feature in the distance.

3.4 Recognisable feature or interim waypoint is approached in a direct line from the startpoint.

4. Employ improvised time measuring techniques

4.1 Elapsed time is estimated by measuring the angle of a segment of the sun’s transit and applying an angle by rate calculation.

4.2 Elapsed time is estimated by measuring the rotation of a celestial body around the celestial pole, and applying an angle by rate calculation.

5. Employ improvised distance measuring techniques

5.1 Distance is estimated by counting number of paces taken and applying a paces by length of pace calculation.

5.2 Distance is estimated by travelling at constant estimated velocity and applying a velocity by time calculation.

6. Determine overall position relative to start point and navigate back

6.1 Grid system using a standard scale is plotted on a sheet of paper, and cardinal points and start point are annotated.

6.2 Physical navigation movements are plotted as scaled vectors from the start point.

6.3 Individual navigation vectors are aggregated to determine final position relative to the start point.

6.4 Return vector is determined in order to return to the start point.
