1. Define parallel forms reliability and split-half reliability. Explain how they are assessed.
Parallel forms reliability is a type of measure of reliability that you can get by doing different types of assessment. They must both have same construct and knowledge system with the same group of people. You must make two parallel forms and create a questionnaire that will have the same system and by random divide the questionnaire into two different sets. Between the two parallel forms whatever correlation is recognized is the reliability. This can be very like split-half reliability. The biggest difference between parallel form reliability and split-half reliability is the way the two are constructed. Parallel forms are done so that both forms are independent of one another and are of equivalent measure. With split-half reliability the whole sample of all the people are calculated and the total score for each randomly divide half.

2. Define internal and external validity. Discuss the importance of each.
Internal validity is how well or to what degree in which your results likely to the independent variable and not of another explanation. You will use this to test your hypothesis. While external validity is the degree to which your results of the case can be concluded. Internal validity is important to show the cause and effect relationship. It shows if the conclusion is outstanding or lacking. If the study shows a higher degree of internal validity we know that a
In my point of view assessment is a testing tool by which a teacher or assessor can use to detect the outcomes of teaching, learning or assessment process with the learners by
Questioning is a method of testing knowledge by asking the learner a series of questions related to the performance criteria. It is important that the assessor plans the questions beforehand, ensuring that open questions are used, and identifies the means of recording them, whether it be written; voice recorded or videoed. Questioning can be a very useful assessment method used alongside other methods. With observation, in particular, ‘what if’ questions can be used for evidence that might be hard to obtain, for example.
Haydn (2009 cited in Capel et al 2009 page 329) defines assessment as "all those activities which are undertaken by teachers, and others, to measure the effectiveness of teaching and learning".
Aim: The aim of this unit is to assess the knowledge and understanding a learning and development practitioner requires for the internal quality assurance of assessment. “Practitioner‟ means anyone with a learning and development responsibility as the whole or a part of their role.
You must be clear of the E to P link (performance clarity) What constitutes good performance?
The function of assessment in learning and development is primarily to provide a measurable barometer for the students progress.
Internal validity is isolating certain variables to determine how well an experiment goes. In your example, we are determining the link between sleep and a decrease in grades. An internally valid conclusion would be that more sleep equals better grades and less sleep leads to a decrease in grades.
The reliability of an assessment in a perfect situation should produce the same results if marked by another tutor or if that examiner unknowingly receives the same paper again. If different marks are given the assessment is consequently unreliable and proves that this assessment is subjective.
Explain the purpose and benefits of letting other people know work plans need to be changed
The roles of the assessor may not be strictly that of a teacher but more of a mentor guiding a Learner to there eventual goal of gaining the qualification by giving appropriate feedback.
Initial assessment can be described as set of procedures we go through to determine what previous experience, skills and abilities a learner has. The process may include skills scan screening for numeracy, literacy and language as well as learning styles and skills abilities, and recognise any prior R.P.L .The results of initial assessment should form individual learning plans so that training and support are delivered that will meet the needs of each learner .Formative assessment is the on-going assessment made in order to adapt to learners needs and respond to learning. Formative assessment helps you keep record of learner’s progress and
You should make sure that all your records are legible, and keep them confidential unless you have permission otherwise.
b. Internal validity occurs when a researcher controls all extraneous variables and the only variable influencing the results of a study is the one being manipulated by the researcher. This means that the variable the researcher intended to study is indeed the one affecting the results and not some other,
Evidence needs to be authentic and actually related to the performance of the learner being assessed and not that of another learner instead.
Parallel and alternate forms—The parallel and the alternative forms of test reliability utilize multiple instances of the same test items at two different time with the same participants (Cohen & Swerdlik, 2010). These kinds of test of reliability measurement could be proper when a person is measuring traits over a lengthy period of time, but would not be proper if a person was to measure one’s emotional state.
