Examine and assess trees

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

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Determine tree survey program requirements

1.1 Identify scope of survey in accordance with client needs

1.2 Determine client’s risk threshold

1.3 Determine and document procedures for data capture

1.4 Identify, source and record all current data research relevant to survey requirements

1.5 Check equipment for assessing trees and prepare for use

1.6 Select, check and use personal protective equipment

2. Determine the tree dimensions and structure

2.1 Plot tree location on a device, drawing or plan of the site

2.2 Determine and record tree dimensions and structure

2.3 Measure tree height, spread and diameter-at-breast height (DBH)

2.4 Examine and record form of tree

2.5 Assess tree for asymmetry of canopy

2.6 Assess if tree has a lean and calculate the lean

2.7 Assess how form of crown relates to or is responsive to surrounding trees and structures

2.8 Determine the potential impact of wind loading of the tree

3. Record tree taxonomic features

3.1 Inspect tree and record fruit type and characteristics

4. Assess tree health issues

4.1 Examine and record the canopy density and distribution

4.2 Assess recorded leaf colour and size against a healthy specimen
