Along with using a phonetic or traditional-motor approach during intervention‚ it may also be appropriate to use auditory input therapy. According to Bowen (2011)‚ this type of therapy can be used with very young children as long as their parents or caretakers are involved as well. It includes minimal meaningful contrast therapy and metalinguistic activities. For example‚ this therapy would contain interesting games and activities where the child is exposed to several repetitions of particular

will require an increase in the quantity of factor inputs which will lead to an increase in costs. The theory of cost is the study of how the cost of production changes as the output level changes. This chapter gives an exposition of the theory of cost. 2 2.1 SHORT-RUN THEORY OF COST Distinction between fixed costs and variable costs Fixed costs are costs that do not vary with the output level as they are associated with fixed factor inputs. In other words‚ an increase in the output level

is the most common and widely used input device.Using a keyboard for too long can lead to health problems such as repetitive strain injury (RSI).To try to overcome this‚ different styles of keyboard have been developed‚ for example‚ the ergonomic keyboard. They are supposed to put your hands into a much more natural position than a traditional keyboard. Advantages:- The advantages of keyboard are: 1. Keyboards have special key that preform specific functions. 2. Instead of using the mouse to

Input‚ Intake‚ and Output in One-Way Drawing Task By Yan Lin It is agreed that input plays a critical role in language acquisition thus researchers have done many studies on input. Without input the learner has nothing. But the question is what kind‚ form and amount of input is most useful for the language learners. Krashen (1980) has argued that the input given to the learners has to be comprehensible for acquisition to happen. He defined it as input which is slightly

Initial Assessment Assessment is the means by which decisions are made on the competency of a learner. The tasks for assessment can take many forms and it is important the assessor is able to make a quality decision and that the judgement they make is fair and comparable to those of other assessors in similar situations. An initial assessment should take place between the learner and the assessor to establish how the learner will benefit from the process of assessment and to enable him/her to
