Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented.

Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes.

Make sure evidence is gathered across the range as expressed under the title. Specific range statements under individual outcomes or assessment criteria are illustrations, from which Learning Programme developers can select. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the learner is able to perform in the real situation.

Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria. The assessment criteria provide the specifications against which assessment judgements should be made.

In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques.

Where this is required, there will be assessment criteria to specify the standard required. The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the learner can achieve the outcomes again and again and again.

This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.

International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research. Learners credited with this unit standard are able to write/sign to suit a range of contexts. They use complex sentence structures and show/register some control of . Properties described are light weight, corrosion resistance, electrical and thermal conductivity, reflectivity, ductility, impermeability, odourlessness and recyclability. The advantages of .

All assessments should be conducted in line with the following well documented principles of assessment: Additive multilingualism A form of bilingual education in which the language of instruction is not the 1st language of the children, and is not intended to replace it.

In an additive bilingual education programme the first language is maintained and supported, but the language of learning and teaching is taught alongside it.

Coherence is to do with ideas and meanings. A paragraph see definition below is coherent if all its sentences see definition below are connected logically so that they are easy to follow.

Cohesion Linking ideas by means of language e. Collage A form of art in which a variety of materials, such as photographs, fabric, objects, hand-drawn pieces, and printed text, are attached to a surface.

Learners can demonstrate their understanding of many themes and issues through the choice of materials and design elements of a collage. Colloquialism A word or expression used in everyday conversation but not in formal language. Ways of doing this can include use of space, head movements, eye gaze, body orientation and movements, etc.

Controlling idea An important or central concept, theme, or argument that is used to unify a signed, written, oral, or media text. Conventions Accepted practices or rules in the use of language. Some conventions help convey meaning e. Creative thinking The process of thinking about ideas or situations in inventive and unusual ways in order to understand them better and respond to them in a new and constructive manner.

Learners think creatively in all subject areas when they imagine, invent, alter, or improve a concept or product. Diction The choice of words or phrases or signs in speech or writing or signing; the particular words or phrases or signs chosen to express an idea.

The SASL equivalent of this would be a signed narrative. Figurative language Words or signs or phrases used in a non-literal way to create a desired effect e.

Fluency The word comes from the flow of a river and suggests a coherence and cohesion that gives language use the quality of being natural, easy to use and easy to interpret.Find databases and other electronic resources to aid your research.

motor. Material testing equipment is generally used for destructive type of testing, which finds out the physical properties of materials before their intended usage. Testing of these materials is required to determine the type of material to be used for manufacturing a particular product.

The use of secondary steelmaking (ladle metallurgy) and degassing enhanced the inclusion control and morphology as well as bringing upon better accuracy on the final properties of steel and precise final composition of steel (Kor & Glasw, ).
