The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
The Competition Model is a psycholinguistic theory of language acquisition and sentence processing, developed by Elizabeth Bates and Brian MacWhinney (1982). [1] The claim in MacWhinney, Bates, and Kliegl (1984) [2] is that "the forms of natural languages are created, governed, constrained, acquired, and used in the service of communicative functions."
The diagram on the right shows a very simplified plot which shall be used to explain the general shape of the plot. The outer edges of the diagram, the envelope, show the possible conditions that the aircraft can reach in straight and level flight.
Skip-gram language model is an attempt at overcoming the data sparsity problem that the preceding model (i.e. word n-gram language model) faced. Words represented in an embedding vector were not necessarily consecutive anymore, but could leave gaps that are skipped over. [6]
The V-Model reflects a project management view of software development and fits the needs of project managers, accountants and lawyers rather than software developers or users. Although it is easily understood by novices, that early understanding is useful only if the novice goes on to acquire a deeper understanding of the development process ...
The Input Processing Theory has faced criticism. Opponents refuse the ‘acquisition-by-comprehension’ claim, as various processes may determine comprehension and production of language, [4] and there is disagreement regarding how to distinguish input and intake. [4] Some researchers claim that VanPatten's model ignores output. [4]
The acquisition–learning hypothesis claims that there is a strict separation between acquisition and learning; Krashen saw acquisition as a purely subconscious process and learning as a conscious process, and claimed that improvement in language ability was only dependent upon acquisition and never on learning.
This acquisition process takes place in natural contexts of majority language settings. The main suggestion of the theory is that the acquisition of a second language is directly linked to the acculturation process, and successes are determined by the extent to which they can orient themselves to the target language culture.
