MSL914001A
Prepare practical science classes and demonstrations

This unit of competency covers the ability to manage the day-to-day running of science teaching laboratories and the preparation of practical experiments, demonstrations and field trips.

Application

This unit of competency is applicable to technical assistants and technical officers working in the secondary and tertiary education sectors. It also applies to zoos, aquariums and museums that run education programs. Personnel are required to assess and treat risks associated with practical activities. Some personnel may have the additional role of fire warden, first aid officer or occupational health and safety (OHS) representative. They may also have other skills, such as boating, SCUBA diving or trade qualifications. They may work autonomously but are required to liaise closely with teaching staff about the design and scheduling of practical activities.

Industry representatives have provided case studies to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting. These are found at the end of this unit of competency under the section 'This competency in practice'.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors should ensure that candidates can:

clarify/design practical activities and assess resource needs

work with teaching staff and students to assess risks, develop and implement controls and monitor their effectiveness

prepare laboratory experiments and demonstrations on time with the correct materials and equipment

work with teaching staff and students to ensure all practical activities are performed safely (through demonstrations and monitoring of practical activities)

manage contingencies and resources within level of responsibility

maintain the laboratory fit for purpose

liaise with suppliers to obtain stocks of materials and equipment using enterprise procedures

work effectively with students and staff who may have diverse work styles, cultures and perspectives.

Context of and specific resources for assessment

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

MSL944001A Maintain laboratory/field workplace safety

relevant MSL974000 series of units of competency

relevant MSL975000 series of units of competency.

Resources may include:

laboratory/field work environment, equipment and materials

personal protective equipment and safety equipment

enterprise OHS management system, policies and procedures.

Method of assessment

The following assessment methods are suggested:

review of operational plans, schedules and budgets prepared by the candidate

review of risk assessments and treatment strategies prepared by the candidate

review of job cards detailing completed tasks

feedback from students, teaching staff, suppliers and supervisor

observation of the candidate assisting teaching staff and students during practical activities

written or oral questions to partly assess the candidate's knowledge of relevant enterprise procedures, technical details of common practical activities and his/her ability to handle a range of contingencies.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Education (1)

A biology class returns from a short excursion where pond water samples have been collected. The teacher plans for the students to identify some of the common microscopic organisms present in the samples and conduct a range of tests for pH, electrical conductivity, turbidity and the presence of nitrates. The teaching assistant prepares, checks and calibrates the monitoring equipment and sets out ten microscopes with clean slides, cover slips and transfer pipettes together with waste buckets and bags for collection of biological material. A sharps container is set out for broken slides and cover slips. At the end of the class, the assistant cleans, checks and stows the microscopes and collects the waste material for disposal. The assistant disposes of the waste according to enterprise procedures.

Education (2)

A technical officer has responsibility for the technical support of practical classes in two laboratories. Every semester, he/she prepares a detailed schedule for all classes and field trips in collaboration with the teaching staff. This involves a careful assessment of risks and implementation of controls for each kind of activity to ensure that the institution meets its OHS and environmental management responsibilities. The schedule must also satisfy the science department budget constraints, seasonal variations and the availability of key staff and items of equipment. The officer's daily routine involves the preparation of all equipment, experiments and demonstrations for classes, the checking of equipment before and after its use, general cleaning and maintenance of equipment and work areas and the maintenance of stock levels.
